Prerequisites

Xcode

Go to http://developer.apple.com/downloads, log in with your Apple ID (free) and download the newest version of either Command Line Tools (OS X Lion) for Xcode or Command Line Tools (OS X Mountain Lion) for Xcode. Run the installer in the dmg and you'll have the LLVM compiler, make, and other build tools.

XQuartz

Install XQuarts to satisfy a library dependency for PHP.

Install Homebrew

Open terminal and run the following steps in the command prompt to install brew and bring it up to date:

ruby <(curl -fsSkL raw.github.com/mxcl/homebrew/go)

brew doctor

brew update

PATH variable

Edit ~/.bash_profile and put /usr/local/bin at the beginning. This command attempts to do this automatically:

echo "PATH=\$(echo \$PATH | sed 's|/usr/local/bin||; s|/usr/local/sbin||; s|::|:|; s|^:||; s|\(.*\)|/usr/local/bin:/usr/local/sbin:\1|')" >> ~/.bash_profile && source ~/.bash_profile

MariaDB

brew install mariadb

MariaDB may use cmake as part of its compilation process, and cmake has java as a dependency. If this pops up during the MariaDB build, choose to Install:

Install Java on OS X popup dialog

Set up MariaDB, set to start on boot, and start now:

unset TMPDIR

mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mariadb)" --datadir=$(brew --prefix)/var/mysql --tmpdir=/tmp

cp -v $(brew --prefix mariadb)/support-files/my-small.cnf $(brew --prefix mariadb)/my.cnf

sed -i "" 's/max_allowed_packet = 1.*M/max_allowed_packet = 2G/g' $(brew --prefix mariadb)/my.cnf

egrep "^# Uncomment the following if you are using InnoDB tables$" $(brew --prefix mariadb)/my.cnf &>/dev/null && sed -i '' "s/^\(# Uncomment the following if you are using InnoDB tables\)$/\1@innodb_file_per_table/; y/@/\n/; s/^#\(innodb_.*\)/\1/g" $(brew --prefix mariadb)/my.cnf

[ ! -d ~/Library/LaunchAgents ] && mkdir -v ~/Library/LaunchAgents

[ -f $(brew --prefix mariadb)/homebrew.mxcl.mariadb.plist ] && cp -v $(brew --prefix mariadb)/homebrew.mxcl.mariadb.plist ~/Library/LaunchAgents/

[ -f ~/Library/LaunchAgents/homebrew.mxcl.mariadb.plist ] && launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mariadb.plist

$(brew --prefix mariadb)/bin/mysql_secure_installation

PHP

NOTE: These instructions are for PHP 5.3. If you want PHP 5.4, change all instances of php53 to php54, and 5.3 to 5.4. If you want to later switch from php53 to php54, you would need to run brew unlink php53 && brew link php54 for brew to symlink the appropriate files in /usr/local/bin.

Add the dupes and php taps:

brew tap homebrew/dupes
brew tap josegonzalez/php

Install PHP:

brew install php53 --with-mariadb --with-intl --with-imap --with-fpm

Set timezone, and increase timeouts and memory values (this is a single command):

sed -i '-default' "s|^;\(date\.timezone[[:space:]]*=\).*|\1 \"`systemsetup -gettimezone|awk -F"\: " '{print $2}'`\"|; s|^\(memory_limit[[:space:]]*=\).*|\1 256M|; s|^\(post_max_size[[:space:]]*=\).*|\1 200M|; s|^\(upload_max_filesize[[:space:]]*=\).*|\1 100M|; s|^\(default_socket_timeout[[:space:]]*=\).*|\1 600|; s|^\(max_execution_time[[:space:]]*=\).*|\1 300|; s|^\(max_input_time[[:space:]]*=\).*|\1 600|;" $(brew --prefix)/etc/php/5.3/php.ini

Add a PHP error log; without this, you may get Internal Server Errors if PHP has errors to write and no logs to write to (be sure to copy and paste the lines containing USERHOME through the last EOF as a single command):

USERHOME=$(dscl . -read /Users/`whoami` NFSHomeDirectory | awk -F"\: " '{print $2}') cat >> $(brew --prefix)/etc/php/5.3/php.ini <<EOF

; PHP Error log
error_log = ${USERHOME}/Sites/logs/php_error_log
EOF

Install PHP extensions and add configuration to php53:

brew install php53-uploadprogress php53-apc php53-memcache php53-xdebug php53-xhprof

sed -i '' "s|^\(apc\.shm_size=\)[0-9]*M$|\1256M|; s|^\(apc.num_files_hint=\)[0-9]*|\10|;" $(brew --prefix)/etc/php/5.43/conf.d/ext-apc.ini

echo "memcache.hash_strategy=\"consistent\"" >> $(brew --prefix)/etc/php/5.3/conf.d/ext-memcache.ini

Start PHP-FPM and start on boot:

[ ! -d ~/Library/LaunchAgents ] && mkdir -p ~/Library/LaunchAgents

cp -v $(brew --prefix php53)/homebrew-php.josegonzalez.php53.plist ~/Library/LaunchAgents/

launchctl load -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php53.plist

Note that even though php-fpm.conf has _www as the user and group, it will run as your user because you're not loading the plist as root.

Also, php-fpm.conf is pre-configured to have min-servers, kind of like Apache, which are unnecessary on a laptop where you should never be loading more than 2 pages at a time. Consider changing pm = dynamic to pm = ondemand. The comments around that section will explain how to lower the maximum number of FPM processes, which I'd recommend setting to 2, and the timeout value to 5s. PHP-FPM will have to start processes more often, but it'll also kill idle processes when they're no longer needed, saving RAM.

Apache

Add the apache tap:

brew tap homebrew/apache

Due to a bug in OS X's apr-1-config tool, this will create symlinks for the non-existent OSX10.8.xctoolchain directory. You're welcome to try the following brew command without this, but you'll need to run this if it fails to install:

[ "$(sw_vers -productVersion | sed 's/^\(10\.[0-9]\).*/\1/')" = "10.8" ] && bash -c "[ -d /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain ] && sudo bash -c 'cd /Applications/Xcode.app/Contents/Developer/Toolchains/ && ln -vs XcodeDefault.xctoolchain OSX10.8.xctoolchain' || sudo bash -c 'mkdir -vp /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain/usr && cd /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain/usr && ln -vs /usr/bin'"

We'll use mod_fastcgi to run PHP with PHP-FPM:

brew install mod_fastcgi

Create the logs directory:

[ ! -d ~/Sites/logs ] && mkdir -pv ~/Sites/logs

VirtualHosts (be sure to copy and paste the lines containing USERHOME through the last EOF as a single command):

touch ~/Sites/httpd-vhosts.conf

sudo ln -s ~/Sites/httpd-vhosts.conf /etc/apache2/other/httpd-vhosts.conf

USERHOME=$(dscl . -read /Users/`whoami` NFSHomeDirectory | awk -F"\: " '{print $2}') cat > ~/Sites/httpd-vhosts.conf <<EOF
#

#

# For http://localhost in the OS X default location
<VirtualHost _default_:80>
    ServerName localhost
    DocumentRoot /Library/WebServer/Documents

</VirtualHost>
EOF

If you read that closely, you'll see that it's set up to do MassVirtualHosts using the *.dev tld. For example, set up a web root at $HOME/Sites/project and you will be able to view it at http://project.dev without needing to create a separate VirtualHost. A custom log format is used, putting the domain name at the beginning of the line, so you can easily see the output as it related to a project.

Restart Apache (if it was running) and set to start on boot:

sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist

sudo launchctl load -w /System/Library/LaunchDaemons/org.apache.httpd.plist
