Simple Install
Go to "System"->"Administration"->"Synaptic Package Manager"->"Settings"->"Repositories"->"Other Software"->"Add..."
- Add the following APT Line For Maverick Meerkat (10.10) :
deb http://ppa.launchpad.net/chris-lea/php-pecl-extras/ubuntu maverick main
- Add the following APT Line For For Lucid Lynx (10.04)
deb http://ppa.launchpad.net/chris-lea/php-pecl-extras/ubuntu lucid main
Now "Close" and "Reload" and you can install the php5-apc package.
Manual Install
To compile pecl packages yourself you'll need these packages installed. They may already be installed. <source lang="bash"> sudo apt-get install php5-dev apache2-prefork-dev </source>
The version of APC that ships with 10.4 and 10.10 causes problems. You'll need to downgrade it for it to work. When it asks if you want to use the spin locks type in yes. Run the following commands in a terminal:
For Lucid (10.04)
<source lang="bash"> sudo apt-get remove php-apc sudo pecl config-set preferred_state beta sudo pecl install APC-3.1.5 sudo pecl config-set preferred_state stable </source> You may also want to try the steps for Meerkat (below)
For Meerkat (10.10)
This seems to work as of Dec 20, 2010. <source lang="bash"> sudo apt-get remove php-apc sudo pecl install APC </source>
Now you need to set the configuration options for APC. Create or edit the ini file by typing: <source lang="bash"> sudo gedit /etc/php5/conf.d/apc.ini </source>
The contents should be: <source lang="ini"> extension=apc.so apc.shm_size=100M apc.write_lock=1 apc.slam_defense=0 </source>
Restart
Now restart apache and memcached (if you're using it) and try to access your site again. <source lang="bash"> sudo /etc/init.d/apache2 restart sudo /etc/init.d/memcached restart </source>
Version Stuff
Updated Dec 20, 2010:
PECL
- Stable is 3.1.6 Released Nov 20, 2010 -- I think it is OK here
