OS X Yosemite MAMP homebrew Development Setup

A quick update, this was originally written for Yosemite Beta 1, XCode 6 Beta, and PHP56 RC1. Now that the official versions of all those are out, a lot of this post is unnecessary because, well, stable software is much more… stable. Who knew? Anyways, here’s a tl;dr for the stable version:

Original Post:

It’s that time of the year again. Apple will soon release a "new" OS (10.10 Yosemite) and in celebration I’ll format my hard drive and reinstall from scratch and then slowly start reconfiguring my machine for development purposes. So I figured, if I’m going to do it- I might as well document it too. Because, to be honest, I kinda forget what I’ve done… Over a few posts we will look at every step of setting up a Moodle development machine from services configuration through installing Moodle and we’ll document all the tools and commands that are needed along the way. In part one we’ll go over installing Homebrew, git, Apache, MySQL, and PHP. In part two we’ll go over configuring Apache, MySQL, and git, as well as how to use the MDK, git, and JIRA to contribute your code. This post is good for any developer that’s using PHP- not just Moodle. So if you want to set up a Mac to develop in WordPress, Drupal, or whatever- this will get you started.

Starting Point

Sorry, we won’t be starting with the unboxing of a new Mac, because I didn’t have a $2,000 budget for this post. And in fact we won’t even be starting with the OS setup, which is OK because if you’re using 10.7 or newer, then you’re okay. If you’re still running 10.6 I’m going to assume that it’s because Apple locked you out of updates because your machine is too old, jerks. Do yourself a favor, buy a new PC.

Here’s what you’ll need: Internet access (how are you even reading this?), administrative privileges (the account doesn’t have to be admin), and accounts at a couple of websites (or the ability to sign up). I’ll also need your credit card number and the last four digits of your social security number, just leave them in the comments. Just kidding, don’t.

MAPP? MAMP? Meh.

If you spend any amount of time in the Moodle forums you’ll run across all kinds of cool acronyms. Usually the glossary auto-linker will fill your head with some cool new knowledge, but for the sake of thoroughness we’ll go over a few of them here. You may see people talk about their WAMP or MAMP or LAMP server. Generally this describes their server configuration.

If somebody says they’re using WAMP that means that their server is running on "Windows". Lamp would be "Linux" and MAMP – Mac. Though technically it should be "OS X" but OAMP is hard to say. Generally most web softwares don’t need a specific platform to run on, a website can run on any operating system. Generally. Stupid ASP.

The second letter, "A", which in the examples above is consistent means that the web service running on the server is "Apache". There are a variety of web service applications available including IIS, Nginx, lighttpd. Generally the software (i.e. Moodle) doesn’t mandate a specific web server software either. Now it could be that the software (i.e. Moodle) depends on some other software (i.e. PHP) that is not compatible or available on that web server. But again, this isn’t usually a problem.

The Third letter defines the database type. Moodle supports 4 different databases out of the box: MySQL, PostgreSQL, Oracle, and MSSQL. Because Moodle has a sweet database driver ($DB) the database that you use doesn’t really matter- in terms of developing on your machine. If you’re trying to pick a database for a large, live server, it probably does matter. So if you see LAMP, MySQL or LAPP, PostgreSQL. Users of other DB types aren’t so clever so they’ll just say boring stuff like "I’m using Windows Server 2008 RC2 with IIS 7 and MSSQL." instead of WS08RC2IIS7MSSQLFTW, which in my opinion is cooler AND easier to understand.

Finally, the last "P" stands for "PHP" which stands for "PHP Hypertext Preprocessor" which stands for "PHP Hypertext Preprocessor Hypertext Preprocessor" which stands for "All work and no play makes Jack a dull boy." Anyways… You’ll need this. Moodle won’t run with out it, and without a specific version as mentioned in the release notes of the Moodle version you download.

With so many options, how do you choose? Like I said in the title, "Meh". I’m going to assume you’re developing on a Mac, so that rules out Windows and Linux. Apache is by far the most popular web server and is included with OS X. MSSQL and Oracle don’t run on OS X. You need PHP.

So your only real options are MySQL or PostgreSQL, and we’ll cover that in a bit, but first let’s start with "M".

Macintosh (OS X)

We need to do a bit of configuring of our Mac before we dive into setting up services. Mostly this will involve downloading some applications.

Get git

Moodle development is managed using git. git in a nutshell lets you track changes of code from lots of users. If you’re going to be doing Moodle development you MUST use git. Fortunately OS X comes with git included, but you can’t use it. Open up terminal and enter the following command:

which git; git -version

and you’ll end up with a return something like this

which git
/usr/bin/git
git -version
xcode-select: note: no developer tools were found at '/Applications/Xcode.app', requesting install. Choose an option in the dialog to download the command line developer tools.

with a prompt to download XCode command line tools:

Go ahead and download it. It’s also worth it to install Xcode as well. For this post you will need both Xcode 5 which you can download from the Apple Developer site and the Xcode 6 beta. I recommend that you rename Xcode 5 from "xcode.app" to "xcode5.app" and Xcode 6 from "Xcode-beta.app" to "Xcode.app" because most of our toolchain will be using the utilities in Xcode 6. Once Xcode and the command line tools are installed we can now use the version of git included with OS X- however it’s a little dated, and we’re going to install a newer version of git from somewhere else.

When it comes to installing the git binary we have a few different choices. First, we can install the official git version from git-scm.com, second we can install a bundled version of git with a different application like github for Mac or git-tower (both of which we’ll go over later), or third you can use a third-party package manager to install a copy of git for you. This last option is the one we will be using.

Homebrew

Homebrew is self-styled "The missing package manager for OS X" and they really deliver. If you’ve spent any amount of time working on an actual Unix or Linux machine you probably both appreciate OS X’s "Unix roots" and really dislike what Apple has chosen to trim back. Without a package manager like pac-man, apt, or the like, OS X is really limited. Homebrew solves that in a really elegant way, so let’s install it. Open up terminal and copy and paste this single command:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

This command has three requirements, one you need to have administrator access or you’ll not be able to install the program as the /usr/ directory is protected. Two you’ll need internet access as the command downloads the script from github and then passes it to ruby to run. If you don’t have internet access you’ll see an error like this:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)" 
curl: (6) Could not resolve host: raw.github.com

Three, you will need to have the XCode command line utilities installed. You should have already install them. If you don’t have the command line tools installed then you will be prompted to install them:

==> Installing the Command Line Tools (expect a GUI popup): 
==> /usr/bin/sudo /usr/bin/xcode-select --install 
xcode-select: note: install requested for command line developer tools Press any key when the installation has completed.

After that you should be good to go. Just run brew doctor as recommended to make sure everything’s okay.

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)" 
==> This script will install:

Your system is ready to brew.

If you see "Your system is ready to brew." then we can move on to the next step. At this point you do have OS X’s version of git installed. To see your specific version run git --version in terminal:

git --version git version 1.9.3 (Apple Git-50)

That’s the version on my system, which is the bleeding-edge version of git that Apple is shipping on a beta operating system and according to github releases, it was released (at time of this writing) about two and a half months ago. Not to mention it’s a full major release behind. git-scm.com has the latest version of git available as 2.0.3. I like to be a little more up to date than that. If we search the homebrew repository we can see the latest version available is 2.0.2:

brew search git 
bagit           git-extras      git-number      giter8
bash-git-prompt git-flow        git-open        gitfs
easy-git        git-flow-avh    git-review      github-release
geogit          git-flow-clone  git-sh          gitslave
git             git-ftp         git-ssh         legit
git-annex       git-gerrit      git-tf          libgit2
git-archive-all git-imerge      git-tf-2.0.2    libgit2-glib
git-cal         git-integration git-tig         magit
git-cola        git-latexdiff   git-tracker     stgit
git-crypt       git-multipush   git-url-sub     topgit
git-encrypt     git-now         gitbucket

At the time of this writing 2.0.2 is only 13 days old and 2.0.3 is only 5 days old. That’s a much better timeframe for updating. So let’s install the homebrew version of git using brew install git

brew install git 
==> Downloading https://www.kernel.org/pub/software/scm/git/git-2.0.3.tar.gz

zsh completion has been installed to: 
/usr/local/share/zsh/site-functions 
==> Summary /usr/local/Cellar/git/2.0.3: 1328 files, 31M, built in 69 seconds

So you’ll see a couple of things- first we actually installed 2.0.3 and that’s because homebrew isn’t a repository of binaries, it simply manages them, the install actually comes from the main git repository at git-scm (kernel.org). In addition to the vanilla git binary we also get bash completion and man pages. Sweet! Go ahead and check the version again, you may have to quit your terminal session and start a new one.

dannywahlmbp:~ dannywahl$ git --version git version 2.0.3

That’s pretty much it for git, now we can move on to github, where we’ll be managing our source code.

Github

Github is where all the cool kids are storing their code these days. Well, everybody except Moodle and Mahara. But at least they provide copies of their work at github- Moodle at least, I didn’t check Mahara (too lazy to open a new tab…).

Basically Github is "the cloud" for source code versioning. You create a repository there, "clone" it to your machine, edit, and push your changes back to the server. If you’re new to git there are lots of resources available to you. We’ll cover a few basics in this post but mastering it is beyond the scope. I suggest you check out:

• Learn Version Control With Git
• Git –local-branching-on-the-cheap
• Code School – Try Git
• Git Tutorials

Sorry, that list isn’t nearly as fun as anything Buzzfeed has put together, and full disclosure- I learned git just by Moodle development so I can’t vouch for any of the above resources… (then why did I even recommend them? Stupid!) Anyways…

If you do not already have an account at github you will need to go sign up. Once you’ve cleared the hoops of verifying email, etc… log in. Github should provide you with a nice step-by-step tutorial of setting up you Mac. But we’ll do it again, just to be sure!

Log in and head over to your profile, fill in any info you want and then click on the SSH Keys tab on the left. SSH basically lets you securely communicate with the server where you are storing your code. Right now we’ll go through the process of generating an SSH key and storing it on github.

Check for existing SSH Keys

Open Terminal again, now if you’re on a fresh OS install you won’t have to do this but you can. Type the following command:

ls -lsa ~/.ssh

ls is the command to ‘list’ everything in a directory. ~ is short code for your home folder, on a Mac that’s /Users/UserName (by default). / is a folder inside of your home folder. .ssh is the name of the folder. On Unix systems a folder that starts with a ‘.’ will be hidden- no need for chflags! So we’ve put together a command that says "show the contents of the hidden folder ‘.ssh’ inside of my home folder". And that is probably shockingly similar to the AppleScript that you would use to do that too.

If terminal gives you this return:

ls -lsa ~/.ssh ls: /Users/dannywahl/.ssh: No such file or directory

then we need to create the directory with another command (just copy and paste):

mkdir ~/.ssh; chmod 700 ~/.ssh

This will do two things, create the ssh directory, and then make sure only you can access it. You can learn more about Unix permissions here.

If terminal gives you this return:

ls -lsa ~/.ssh/ 
total 16 
0 drwx------ 4 dannywahl staff 136 Jul 31 16:41 . 
0 drwxr-xr-x+ 18 dannywahl staff 612 Jul 31 16:36 .. 
8 -rw------- 1 dannywahl staff 1766 Jul 31 16:41 id_rsa 
8 -rw-r--r-- 1 dannywahl staff 398 Jul 31 16:41 id_rsa.pub

Then you already have an SSH Key. IF you created this key and are sure of its security you can use it with github, skip to the "Adding your SSH Key to Github" section below. Otherwise you can create a new one.

Creating an SSH Key Pair

When you create an SSH key you actually create two keys, a private key and a public key. You keep the private key and you can share the public key with others. This allows them to receive messages and ensure it is from you, but they can’t pretend to be you and send out messages on your behalf. Back in terminal we’re going to create a new RSA SSH key set. Run the command:

ssh-keygen -t rsa -C "email@address.invalid"

This will kick off a "Wizard" of sorts and walk you through creating your key pair. First you need to specify where to save the new keys, the default is your ~/.ssh folder, so just push enter.

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/dannywahl/.ssh/id_rsa):

Note that you can specify a different name, as you can have multiple SSH key pairs. Though for most instances a single pair is all that is necessary.

Next it will ask you for a key passphrase, which is optional. I strongly suggest that you add a passphrase for both added security and the fact that other SSH applications (not github) require a passphrase to function properly and if you want to reuse your key pair you will need a passphrase. Type your passphrase press Enter and type it again to make sure it matches.

Enter passphrase (empty for no passphrase): 
Enter same passphrase again:

After that your key pair will be save and you will be given some information about it. It will look something like this:

Your identification has been saved in /Users/dannywahl/.ssh/id_rsa. 
Your public key has been saved in /Users/dannywahl/.ssh/id_rsa.pub. 
The key fingerprint is:
fa:e7:5c:f2:60:d8:ad:44:3c:a4:07:0d:b5:09:77:9f
danny@iyware.com 
The key's randomart image is:
+--[ RSA 2048]----+ 
| =A+ . | | *=* . |
| +.=oE . | | . o= 
= | | .S . | | . | 
| | | | | | 
+-----------------+

The finger print and randomart allow you to verify that a public key copy is a real copy. Please note that these are NOT my real public key credentials. On that note you should NEVER share your private key with anyone.

Activating Your Key

Now that you have created your key you need to tell the operating system to use it. We will use the ssh-add command to load your key. Enter this command, and then type your key passphrase. If you didn’t enter a passphrase, simply press Enter.

ssh-add ~/.ssh/id_rsa 
Enter passphrase for /Users/dannywahl/.ssh/id_rsa:
Identity added: /Users/dannywahl/.ssh/id_rsa (/Users/dannywahl/.ssh/id_rsa)

Copy Your Public Key to Github

The final step is to give github a copy of your public key. If you don’t have the SSH Keys page open you will need to navigate there and click "Add SSH Keys". You can store more than one key with github, which is useful if you have multiple devices that you do development from.

Back in terminal you have one more command to run, simply copy and paste (unless you renamed your key):

pbcopy < ~/.ssh/id_rsa.pub

This command copies the contents of your public key to your clipboard. You can also open your key in a text editor and copy the contents but this command prevents both omitting a character and accidentally editing the key. Switch back to github and paste in the "Key" field. If there’s a blank line at the end, that’s ok- don’t erase it. Remember we want the contents of the key exactly.

You’ll want to give you key a title so that if you ever have a security issue at github you can see exactly which machine accessed or changed which repositories. Your page should look something like this:

Click the "Add key" button and you’ll be taken back to the SSH Keys page, where your new key will be listed. If you look at terminal you’ll notice that the fingerprints match.

For now we’re done with github. So far we’ve set up homebrew, installed git, created an SSH key pair, and added a copy of our public key to github. Next we’ll start setting up the "server" side of our development machine, starting with Apache.

Apache

The Apache HTTPD server is the most popular web server in the world. And in fact Apache is included with OS X by default. Just copy and paste this command into terminal:

apachectl -v

Mine says:

Server version: Apache/2.4.9 (Unix) Server built: Jun 28 2014 12:11:10

Which is actually not that bad. Apache is one of those softwares that updates rather slowly, 2.4.10 was released on July 10th. Since Apache is included in OS X we can just use that right? Sure, just visit this link: http://localhost. Oops, does your screen look something like this?

That’s because even though Apache is included in OS X it’s off by default. We have a few options available that we’ll look at to enabling Apache.

The Apple Way

Even though Apple includes Apache as a part of OS X, and they used to include an option to enable it in the "Sharing" pane of System preferences, the preferred way to enable Apache on OS X since 10.7 is to buy the Server app from the App Store. That’s right, for only $19 Apple will sell you a button that starts Apache.

The Poor Man’s Way

The second option is to simply start Apache ourselves. Go to terminal and type this command:

sudo apachectl start

After you type your password head back to http://localhost and it should look more like this:

$20 bucks for that. To be fair to Apple, Server does give you lots of other functionality but for our purposes they’re not really necessary. Kind of like installing XCode to use git. Now, I’m going to recommend that you actually stop the Apache service because we are not going to use the built in version that Apple ships with.

sudo apachectl stop

The Homebrew Way

The reason we’re not going to use the version that ships with Apple is because they do a TON of customization to the Apache configurations and it makes it really difficult to simply add a vhost or edit a config. You even have to mess with groups to allow yourself to change files in your ~/Sites folder. Instead we’re going to install Apache via Homebrew and it will run entirely within your home folder.

First we need to unload the OS X version of Apache which is loaded on the machine at startup, but "stopped". Copy and paste this into terminal.

sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/null

Next we need to do is add the Apache repository to the list of repositories that Homebrew tracks, as it is not included by default.

brew tap homebrew/apache

and you’ll see that the repository is downloaded and 9 new forumlae are available for install.

brew tap homebrew/apache

Tapped 9 formulae

The new repository gives us two versions of Apache: 2.2 and 2.4. For our development we will be installing Apache 2.4, however when we try we end up with an error:

brew install httpd24 
Error: No available formula for apr (dependency of httpd24) 
Searching taps... 
homebrew/dupes/apr-util homebrew/dupes/apr homebrew/science/reapr

it seems that Apache 2.4 requires another app called ‘apr’ that isn’t on our system. Fortunately Homebrew does us a favor and tells us where to find it and it’s available in another repository, so we need to add that to our list of available repositories like before:

brew tap homebrew/dupes

According to the ‘dupes’ repository,

These formulae duplicate software provided by OS X, though may provide more recent or bugfix versions.

Now what’s nice is that homebrew will resolve dependencies for us now that it knows where the files are, so let’s try again:

brew install httpd24 –with-privileged-ports

httpd24 will get us the current version of Apache 2.4. The ‘with-privileged-ports’ parameter tells Apache to run on port 80/443 instead of 8080/8443. Essentially this means you can visit http://localhost instead of having to type http://localhost:8080. 80 and 443 are the default ports that all websites run on and for our development purposes are preferable.

If you get an error during compiling please follow the instructions of the output. If you have installed a beta version of Xcode on your machine please do NOT open an issue with the Homebrew people (like this one). Instead head over to the App Store and redownload the old version. If the app store won’t let you download you can go to the Apple Developer Downloads page and download the latest stable version of Xcode to your machine. You don’t have to remove the beta version, but the stable needs to be named ‘Xcode.app’.

Error: Homebrew doesn't know what compiler versions ship with your version of Xcode (6.0). 
Please `brew update` and if that doesn't help, file an issue with the output of `brew --config`:

Note that we only track stable, released versions of Xcode. Thanks!

Another issue I ran into was a configure failure because zlib couldn’t be found:

This is probably a result of using a beta version of the Xcode command line tools, but there’s a simple fix that’s been reported. First you need to install zlib in Homebrew from the dupes repository.

brew install zlib

Homebrew will give you this caveat:

This formula is keg-only, so it was not symlinked into /usr/local. 
Mac OS X already provides this software and installing another version in parallel can cause all kinds of trouble. 
Generally there are no consequences of this for you. 
If you build your own software and it requires this formula, you'll need to add to your build variables:

CPPFLAGS: -I/usr/local/opt/zlib/include

Which basically means that you need to manually use that version of zlib, which is what we’ll tell our Apache build script to do now. Go back to terminal and enter the following command:

brew edit httpd24

This will open the config in your default text editor. Enter this line:

args << "--with-z=/usr/local/Cellar/zlib/1.2.8"

After this section:

if build.with? "privileged-ports"
  args << "--with-port=80"
  args << "--with-sslport=443"
else
  args << "--with-port=8080"
  args << "--with-sslport=8443"
end

That will add a new argument that forces it to use our Homebrew version of zlib. Save the file and run the build again:

brew install httpd24 --with-privileged-ports

If you don't have any errors then your output should look something like this:

brew install httpd24 --with-privileged-ports 
==> Downloading https://archive.apache.org/dist/httpd/httpd-2.4.10.tar.bz2 
Already downloaded: /Library/Caches/Homebrew/httpd24-2.4.10.tar.bz2 
==> ./configure --enable-layout=Homebrew --enable-mods-shared=all --with-mpm=pre 
==> make 
==> make install 
==> Caveats 
To have launchd start httpd24 at login: 
ln -sfv /usr/local/opt/httpd24/*.plist ~/Library/LaunchAgents 
Then to load httpd24 now: 
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.httpd24.plist 
==> Summary /usr/local/Cellar/httpd24/2.4.10: 199 files, 4.4M, built in 86 seconds

Finally it's important that we look at the caveats as they will tell us how to make sure that Apache starts when we log in to the system. Since we used the --with-privileged-ports parameter we will have to make some adjustments to the recommendations that Homebrew provides. Their recommendation is to create a symlink to your user LaunchAgents folder. That folder contains plists that do certain things when you log in. However, on a Unix system lower ports like 80 require root to run. Since this launch agent is launching Apache under your username it will quietly fail. Instead we will have the system (root) load it for us. The biggest difference is that Apache will be loaded at system start instead of when you log in. So go ahead and copy and paste this modified command into terminal.

sudo ln -sfv /usr/local/opt/httpd24/*.plist /Library/LaunchDaemons;
sudo launchctl load /Library/LaunchDaemons/homebrew.mxcl.httpd24.plist

Now the next time you reboot Apache will load. But the beautiful thing about a service is that you can start, stop, or reload it at any time- we don't need to log out and log in again to start. Now, since we're running Apache as root we will need to use sudo. So it's not necessary now, because we just loaded it, but for the future you can use:

sudo httpd -k start 
sudo httpd -k restart 
sudo httpd -k stop

for more info you can check the manual man entry that's included with our Apache install.

man httpd

Now Apache is installed (by you) and running (as root). Go ahead and go back to http://localhost and you should see this:

By default the Apache configuration files are stored in /usr/local/etc/apache2/2.4 and the web root is at /usr/local/var/www/htdocs. We'll revisit further Apache configuration when we get to Moodle setup, but for now enjoy your shiny new site!

MySQL, uhh.. PostgreSQL

The next step on setting up our MA*P server is the database. In the old, olden days of 3 years ago OS X included MySQL in OS X server. Then Apple switched to Postgres. Then Apple bundled Postgres with the OS and added an 'enable' button in the Server app (a la Apache). And now starting with OS 10.9 it's back to being bundled exclusively with the Server App. tl;dr: you need to install a database, and I figure if it's so trivial for Apple to switch databases then it doesn't really matter which one we're using, right? ;)

Ok, here's the exception, if you're planning on developing some sort of Moodle plugin, or fixing bugs that are database oriented, then you'll probably want to install multiple database drivers. But for simpler development where Moodle $DB handled the transactions, pick your poison. I'm going to use MySQL. So let's head back to the Homebrew app in terminal and get started:

brew install mysql

Ok, caveat. If you happen to be on an as-of-yet-unreleased OS and have both Xcode 5 and Xcode 6 beta installed on your system you will need to use Xcode 6 to install MySQL otherwise this will happen:

It's nice that they give you a log to inspect, but it's also kind of annoying that the /tmp dir gets cleaned up one it's done failing... Basically if you can capture the log in Console while it's failing you'll see that something in the Xcode tool is causing the failure. I guessed that it was because of Xcode 5 - and hey, lucky guess! So if you have that error drop into terminal and use this command:

mv /Applications/Xcode.app /Applications/Xcode5.app;
mv /Applications/Xcode6-beta4.app /Applications/Xcode.app

Or just go to the /Applications folder and rename them, your choice. Then run the install command again. When the build is done you can move your Xcode apps back to their original names. If all goes well you should end up with some terminal output like this:

A "/etc/my.cnf" from another install may interfere with a Homebrew-built server starting up correctly. 
To connect: 
mysql -uroot 
To have launchd start mysql at login: 
ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents 
Then to load mysql now: 
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist 
Or, if you don't want/need launchctl, you can just run:
mysql.server start 
==> /usr/local/Cellar/mysql/5.6.20/bin/mysql_install_db --verbose --user=dannywa 
==> Summary /usr/local/Cellar/mysql/5.6.20: 9578 files, 339M, built in 7.2 minutes

Now that's pretty amazing to me, and where homebrew is really worth its salt. All of those dependencies managed, auto downloaded, configured, and installed: cmake, pkg-config, makedepend, openssl, and finally mysql. There's no way I could have done that in 7.2 minutes manually.

Generally MySQL runs at a high enough port that it can run in user space, so you don't need to sudo it into the /Library/LaunchAgents folder, it's ok to run it from your home folder, so go ahead and follow the instruction on screen:

ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents; 
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

That will load MySQL. Now we'll test it and make some configuration changes. In shell we will connect to the mysql server:

mysql -u root

You will now drop into a MySQL prompt that should look something like this:

Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 3 
Server version: 5.6.20 Homebrew 

Copyright (c) 2000, 2014, Oracle and/or its affiliates. All rights reserved. 

Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. 

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. 

mysql>

Notice that we have version 5.6.20 Homebrew - helpful in identifying that we are connected to the correct database. Now at the prompt (mysql >) we will set a password for the root account. It's not only good practice, it's required by some software. Obviously in a production server you would worry about security- but for a dev server using root is A-OK in my book. To set the root password enter this command:

exit;

No, that didn't really change the root password. That simply disconnected from the MySQL server and dropped us back into our standard shell. You see, there's a simple command called mysqladmin that's been installed for us as well which makes it much easier to change the password. Now we will use this command:

mysqladmin -u root password "newpwd"

Please substitute "newpwd" for the password you want to use for the root account. I use "root" (no quotes). Again- it's a dev. server. Remember that the MySQL docs recommend only alphanumeric characters for MySQL passwords. If you run into log in issues later it might be because of special characters. Now, let's try to connect to mysql again as above and you should get an error:

mysql -u root ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

If you want to connect via terminal in the future you will have to use the -p flag like so:

mysql -u root -p

After which you will be prompted for the password which you just set.

For now that's the basic configuration of MySQL, we'll cover creating databases later when we go into Moodle setup.

PHP

PHP is one of the most popular dynamic languages out there. It's robust, it's solid, and it's what Moodle uses. So let's install it. Once again, OS X ships with PHP installed, but we're going to disable it and replace with the Homebrew version. My shipped version is 5.5.9 (cli) which was released on Feb 4, 2014. The latest stable version is 5.5.15:

php -v 
PHP 5.5.9 (cli) (built: Jun 28 2014 15:59:38) 
Copyright (c) 1997-2014 The PHP Group 
Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies

Now, before we install PHP we need to remember that Moodle requires and recommends a lot of submodules:

• php
• pcreunicode
• php_extension iconv
• php_extension mbstring
• php_extension curl
• php_extension openssl
• php_extension tokenizer
• php_extension xmlrpc
• php_extension soap
• php_extension ctype
• php_extension zip
• php_extension zlib
• php_extension gd
• php_extension simplexml
• php_extension spl
• php_extension pcre
• php_extension dom
• php_extension xml
• php_extension intl
• php_extension json
• php_extension hash

Man that's a lot of requirements/recommendations, fortunately Homebrew is going to provide us a lot of flexibility in getting everything installed. First we're going to need to tap two new repositories 'versions' and 'homebrew-php':

brew tap homebrew/versions;
brew tap homebrew/homebrew-php

If everything goes well your output should look something like this:

brew tap homebrew/versions 
Cloning into '/usr/local/Library/Taps/homebrew/homebrew-versions'...

Next you'll need to decide which version of PHP you want. I'm going to use PHP 5.6 even though it's only at RC1 as of this writing because I really want to try phpdbg. If nobody tests release versions of software then how will the bugs be found? Let's take a look at what options are available to us by running this command:

brew options php56

and we get quite a few options:

brew options php56 
--disable-opcache 
  Build without Opcache extension 
--homebrew-apxs 
  Build against apxs in Homebrew prefix
--with-apache 
  Enable building of shared Apache 2.0 Handler module, overriding any options which disable apache 
--with-cgi 
  Enable building of the CGI executable (implies --without-apache) 
--with-debug 
  Compile with debugging symbols 
--with-fpm 
  Enable building of the fpm SAPI executable (implies --without-apache) 
--with-gmp 
  Build with gmp support 
--with-homebrew-curl 
  Include Curl support via Homebrew 
--with-homebrew-libxslt 
  Include LibXSLT support via Homebrew 
--with-homebrew-openssl 
  Include OpenSSL support via Homebrew 
--with-imap Include 
  IMAP extension 
--with-intl 
  Include internationalization support 
--with-libmysql 
  Include (old-style) libmysql support instead of mysqlnd 
--with-mssql 
  Include MSSQL-DB support 
--with-pdo-oci 
  Include Oracle databases (requries ORACLE_HOME be set) 
--with-pgsql 
  Include PostgreSQL support 
--with-phpdbg 
  Enable building of the phpdbg SAPI executable (PHP 5.4 and above) 
--with-thread-safety 
  Build with thread safety 
--with-tidy 
  Include Tidy support 
--without-bz2 
  Build without bz2 support 
--without-mysql 
  Remove MySQL/MariaDB support 
--without-pcntl 
  Build without Process Control support 
--without-pear 
  Build without PEAR --HEAD install HEAD version

Even though it's probably not required for php56 I'm going to use the --with-phpdbg flag just to be safe. In addition I'm going to use a few other options for homebrew versions of software. Since we've already installed Homebrew OpenSSL we'll use that, as well as APXS and Curl. Apxs is a tool for building Apache modules (like PHP) - since we're using a newer version of Apache than shipped with OS X we should probably use a newer version of APXS too. Curl is another one of those tools that's slightly outdated and we may as well use the latest stable version. The version on my system is 7.30.0, and at the time of this writing the version shipping with Homebrew is 7.37.1. I've also used --with-tidy because if I recall correctly Moodle text editors can leverage it for WYSIWYG input. Finally, notice that we're not using the --with-intl flag, that's because currently intl is broken and we'll have to install a separate package after PHP builds. Here's my full install command (copy and paste):

brew install php56 --homebrew-apxs --with-apache --with-homebrew-curl --with-homebrew-openssl --with-phpdbg --with-tidy

If you get an error about missing bzip2 like this:

Then you will need to edit the formula to set the path of your bzip2 binary manually. First, find where your bzip2 binary is located with the following command:

which bzip2

Then edit the forumula for php:

brew edit php56

and add this line:

args << "--with-bz2=/usr/bin/bzip2"

after these lines:

def install_args args = super

Another common error that seems to be occuring, and has been reported (here) is a compilation error while building phar. The basic error is:

make: *** [ext/phar/phar.phar] Illegal instruction: 4

or

/Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_require.rb:55:in require': Class is not a module (TypeError)

I found this to be an error of trying to use Homebrew's OpenSSL, either by setting it as the default on the system or using the --with-homebrew-ssl flag. So for now my build is using the system version of OpenSSL. If the build goes correctly then your total output should look something like this:

Warning: Backing up all known pear.conf and .pearrc files
Warning: If you have a pre-existing pear install outside
         of homebrew-php, or you are using a non-standard
         pear.conf location, installation may fail.
==> ./configure --prefix=/usr/local/Cellar/php56/5.6.0-rc.3 --localstatedir=/usr

==> Caveats
To enable PHP in Apache add the following to httpd.conf and restart Apache:
    LoadModule php5_module    /usr/local/opt/php56/libexec/apache2/libphp5.so

The php.ini file can be found in:
    /usr/local/etc/php/5.6/php.ini

✩✩✩✩ PEAR ✩✩✩✩

If PEAR complains about permissions, 'fix' the default PEAR permissions and config:
    chmod -R ug+w /usr/local/Cellar/php56/5.6.0-rc.3/lib/php
    pear config-set php_ini /usr/local/etc/php/5.6/php.ini

✩✩✩✩ Extensions ✩✩✩✩

If you are having issues with custom extension compiling, ensure that
you are using the brew version, by placing /usr/local/bin before /usr/sbin in your PATH:

      PATH="/usr/local/bin:$PATH"

PHP56 Extensions will always be compiled against this PHP. Please install them
using --without-homebrew-php to enable compiling against system PHP.

✩✩✩✩ PHP CLI ✩✩✩✩

If you wish to swap the PHP you use on the command line, you should add the following to ~/.bashrc,
~/.zshrc, ~/.profile or your shell's equivalent configuration file:

      export PATH="$(brew --prefix homebrew/php/php56)/bin:$PATH"

To have launchd start php56 at login:
    ln -sfv /usr/local/opt/php56/*.plist ~/Library/LaunchAgents
Then to load php56 now:
    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.php56.plist
==> Summary
  /usr/local/Cellar/php56/5.6.0-rc.3: 497 files, 50M, built in 5.9 minutes

As you can see looking at the caveats there are still a few steps we need to do. First we will fix the PEAR permissions, this might not be necessary, but it won't hurt anything so go ahead and copy and paste these commands into the terminal:

chmod -R ug+w /usr/local/Cellar/php56/5.6.0-rc.3/lib/php
pear config-set php_ini /usr/local/etc/php/5.6/php.ini

Next we'll make sure that PHP gets loaded at login by the launchd and load it now, too:

ln -sfv /usr/local/opt/php56/*.plist ~/Library/LaunchAgents 
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.php56.plist

Then we'll check our command line version. First, exit or Quit Terminal and reopen it, then run this command in terminal:

php -v

The output should have 5.6 listed as the version, like this:

php -v 
PHP 5.6.0RC3 (cli) (built: Aug 7 2014 10:21:55) 
Copyright (c) 1997-2014 The PHP Group 
Zend Engine v2.6.0-dev, Copyright (c) 1998-2014 Zend Technologies

If it lists 5.5 as the version then you need to update you $PATH variable. Depending on the version of shell your're running you need to add the following line to your terminal config (default ~/.profile). The following commands should add it for you:

touch ~/.profile
cat >> ~/.profile <<EOF
export PATH="$(brew --prefix homebrew/php/php56)/bin:$PATH"
EOF

Now you can exit Terminal and reopen it and run php -v again.

Finally you need to add the php handlers to the httpd.conf. Open up /usr/local/etc/apache2/2.4/httpd.conf and add the following three lines to the document:

LoadModule php5_module /usr/local/opt/php56/libexec/apache2/libphp5.so 
AddHandler php5-script .php 
AddType text/html .php

and find the line that starts with DirectoryIndex and change it to read:

DirectoryIndex index.php

Save the document and then restart the httpd service with the following command:

sudo httpd -k restart

Now we having functioning PHP on our server, but remember we need to install intl separately, so go back to terminal and run the following command:

brew install php56-intl

When it finishes building you should have output similar to this:

brew install php56-intl

This formula is keg-only, so it was not symlinked into /usr/local.

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/icu4c/lib
    CPPFLAGS: -I/usr/local/opt/icu4c/include

    do not forget to remove it upon extension removal.
  * Validate installation via one of the following methods:
  *
  * Using PHP from a webserver:
  * - Restart your webserver.
  * - Write a PHP page that calls "phpinfo();"
  * - Load it in a browser and look for the info on the intl module.
  * - If you see it, you have been successful!
  *
  * Using PHP from the command line:
  * - Run "php -i" (command-line "phpinfo()")
  * - Look for the info on the intl module.
  * - If you see it, you have been successful!

And there we have it! That will give us every required Moodle php extension, except for opcache, which at the time of this writing is not compatible with PHP 5.6. When it does become available you can simply run brew install php56-opcache and you're done.

Wrapping Up

That's the end of the first part of this extensive walk through of setting up a Moodle development server. This first part should really help anyone doing any sort of PHP development on a Mac whether it's WordPress, Drupal, or whatever. In part two we'll dive into configuring Apache and MySQL for Moodle development as well how to use the MDK, git, and JIRA to contribute your code and bug fixes back to the community.
