Drupal on Lion (OS X 10.7)   15 February 2012

I was half way done adding some info how to setup pecl/pear to my guide to running Drupal 6 on OS X 10.6 before I realized I’d been running Lion for almost nine months. So it seemed like a good excuse to update it for Lion. These might be a little wonky since I did an upgrade rather than a clean install so if you notice anything please drop me a line.

Note:I’ll save you the trouble of commenting, I am familiar with MAMP but would rather punch myself myself in the face than use it. If you’d like to, go right, but I’m going to continue to compile my own so I know where everything ends up.

Install XCode

Install XCode from the App Store.

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
Password:
sh-3.2#

Install MySQL

Use port to install MySQL:

/opt/local/bin/port install mysql5-server

You’ll need to create the databases:

/opt/local/bin/mysql_install_db5 --user=mysql

Let launchd know it should start MySQL at startup.

/opt/local/bin/port load mysql5-server

Secure the server and set a new admin password:

/opt/local/bin/mysql_secure_installation5

Create a configuration file:

cp /opt/local/share/mysql5/mysql/my-large.cnf /etc/my.cnf

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:

/opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper restart

A last, optional, step is to create a symlink for the mysql5 executable so can be invoked as mysql and mysqldump5 as mysqldump:

ln -s /opt/local/bin/mysql5 /opt/local/bin/mysql
ln -s /opt/local/bin/mysqldump5 /opt/local/bin/mysqldump

PHP

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.

- 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:

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

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:

/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:

extension=memcached.so

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

XDebug

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

Use pecl to install XDebug:

pecl install xdebug

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

zend_extension="/usr/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so"
xdebug.profiler_enable_trigger = 1

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 d6
    DocumentRoot /Users/amorton/Sites/d6
    <Directory /Users/amorton/Sites/d6>
        AllowOverride All
    </Directory>
</VirtualHost>

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

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

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

127.0.0.1       d6
127.0.0.1       d7

Now you can view your sites at http://d6/ and http://d7/
