Trying to install
php-pecl-apc fails because of a dependency error.
You need to use Pear to install this, which can be done through a simple RightScript or Chef Recipe.
The PECL Demo ServerTemplate has Chef recipes which can be used to install PEAR and PECL packages.
Another option is creating a RightScript. Add the following to the 'Packages' line, to install the necessary resources for APC installation:
php-pear php-devel httpd-devel
And paste this as the body of the script. You can enter custom configuration options in the file apc.ini created by the script:
#!/bin/bash echo no | pear install pecl/apc echo extension=apc.so > /etc/php.d/apc.ini service httpd graceful
