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.

Install MySQL

Use port to install MySQL:

You'll need to create the databases:

Let launchd know it should start MySQL at startup.

Secure the server and set a new admin password:

Create a configuration file:

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

• Change the maximum packet size to 16M:
  
  max_allowed_packet = 16M
• Enable network access by ensuring the first line is commented out but add the second to limit access to the localhost with the second line:
  
  #skip-networking
bind-address = 127.0.0.1

Restart MySQL to have the settings changes take effect:

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

PHP

You need to create a php.ini file:

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

And changing it to:

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:

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

• Uncomment this line:
  
  #LoadModule php5_module        libexec/apache2/libphp5.so
• Find and change this one:
  
      DirectoryIndex index.html

  To this:
  

      DirectoryIndex index.php index.html

Then restart Apache:

Install PEAR / PECL

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

Then add this line to your php.ini:

Now you can update the channels and upgrade the packages:

Drush

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

Memcache

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:

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:

Then we can install the module:

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:

XDebug

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:

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

Then add this one:

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:

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

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

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