Drupal on Mountain Lion (OS X 10.8)   26 July 2012

The instructions still need some work. I’d did some updating but haven’t tried using it with a clean install yet. After reading this it sounds like there’s some bigger changes. I’ve also been trying to switch from macports to homebrew so that’ll also mean some changes to this.

Install XCode

Install XCode from the App Store. Run Xcode and open its Preferences (⌘+,) select the Downloads tab and then the Components sub-tab. Click the Install button on the Command Line Tools component.

Install MacPorts

Follow the directions to install Mac Ports.

Become root

To follow these instructions you need to be running as the root user using the default sh shell. If you’ve got administrator permissions you can open up a Terminal window and switch users using the sudo command then provide your password.

amorton@minivac:~% sudo su

Install MySQL

Use port to install MySQL:

/opt/local/bin/port install mysql55-server

You’ll need to create the databases:

sudo -u _mysql /opt/local/lib/mysql55/bin/mysql_install_db

Let launchd know it should start MySQL at startup.

/opt/local/bin/port load mysql55-server

Secure the server and set a new admin password:


Create a configuration file:

cp /opt/local/share/mysql55/support-files/my-large.cnf /etc/my.cnf

Edit /etc/my.cnf using your editor of choice and make the following changes to the [mysqld]:

max_allowed_packet = 16M
bind-address =

Restart MySQL to have the settings changes take effect:

port unload mysql55-server
port load mysql55-server

A last, optional, step is to create some symlinks for the executables so they’re in the path:

ln -s /opt/local/lib/mysql55/bin/mysql /opt/local/bin/mysql
ln -s /opt/local/lib/mysql55/bin/mysqldump /opt/local/bin/mysqldump
ln -s /opt/local/lib/mysql55/bin/mysqlimport /opt/local/bin/mysqlimport


You need to create a php.ini file:

if ( ! test -e /private/etc/php.ini ) ; then cp /private/etc/php.ini.default /private/etc/php.ini; fi

Now open /private/etc/php.ini and set the correct location for MySQL’s socket by finding:

mysqli.default_socket = /var/mysql/mysql.sock

And changing it to:

mysqli.default_socket = /opt/local/var/run/mysql5/mysqld.sock

Repeat for both mysql.default_socket and pdo_mysql.default_socket.

While you’re editing php.ini you might as well set the timezone to avoid warnings. Locate the date.timezone setting uncomment it (by removing the semi-colon at the beginning of the line) and fill in the appropriate timezone:

date.timezone = America/New_York

Enable PHP by opening /private/etc/apache2/httpd.conf in the editor of your choice and making the following changes.

Then restart Apache:

apachectl graceful

Install PEAR / PECL

I scratched my head for a while on this one before finding this setup guide.

php /usr/lib/php/install-pear-nozlib.phar

Then add this line to your php.ini:

include_path = ".:/usr/lib/php/pear"

Now you can update the channels and upgrade the packages:

pear channel-update pear.php.net
pecl channel-update pecl.php.net
pear upgrade-all


If you’re doing anything with Drupal you’ll find Drush to be indispensable.

pear channel-discover pear.drush.org
pear install drush/drush


You don’t need this to run Drupal but I use it on production servers and I want to try to match the setup.

Use port to install and start memcached:

/opt/local/bin/port install memcached
/opt/local/bin/port load memcached

Since pecl won’t let us pass --with-libmemcached-dir=/opt/local to the configure script, a simple work around is to just add some symlinks:

ln -s /opt/local/include/libmemcached /usr/include/
ln -s /opt/local/include/libmemcached-1.0 /usr/include/
ln -s /opt/local/include/libhashkit /usr/include/
ln -s /opt/local/include/libhashkit-1.0 /usr/include/
ln -s /opt/local/lib/libmemcached.dylib /usr/lib/
ln -s /opt/local/lib/libhashkit.dylib /usr/lib/

Then we can install the module:

pecl install memcached

You’ll need to edit your /etc/php.ini and add the following line:


If you want to clean up the symlinks (which will prevent pecl upgrade from being able to upgrade the module) here’s how you do it:

unlink /usr/include/libmemcached
unlink /usr/include/libmemcached-1.0
unlink /usr/include/libhashkit
unlink /usr/include/libhashkit-1.0
unlink /usr/lib/libmemcached.dylib
unlink /usr/lib/libhashkit.dylib


This is also optional, but I find it’s very hand to use with MacGDBp to debug those tricky issues. It’s also nice to use with webgrind for profiling.

Use pecl to install XDebug:

pecl install xdebug

You’ll need to edit your /etc/php.ini uncomment the following line:


Then add this one:

xdebug.profiler_enable_trigger = 1

Which lets you enable the profiler by appending XDEBUG_PROFILE=1 in the query of a URL.

My VirtualHost Setup

I like being able to have multiple Drupal sites a few keystrokes away so I create virtual hosts for d5, d6 and d7 using the following procedure.

Edit /etc/apache2/users/amorton.conf and add a VirtualHost to the Apache config:

# This should really be in httpd.conf but i'm keeping it simple by doing it here:
NameVirtualHost *:80

<VirtualHost *:80>
    ServerName d7
    DocumentRoot /Users/amorton/Sites/d7
    <Directory /Users/amorton/Sites/d7>
        AllowOverride All
        Allow from all

<VirtualHost *:80>
    ServerName d8
    DocumentRoot /Users/amorton/Sites/d8
    <Directory /Users/amorton/Sites/d8>
        AllowOverride All
        Allow from all

Obviously you’d want to replace amorton with your username.

Add an entries to the /private/etc/hosts file:       d7       d8

Now you can view your sites at http://d7/ and http://d8/
