How to Configure APC Cache on Virtual Servers with PHP running under FCGId

APC INFO Monitor My Virtualmin CentOS 5.6 Virtual Private Server runs several virtual domains with PHP under FCGId using APC for opcode caching: Joomla, PHPbb, WordPress, etc . APC is somewhat challenging to configure properly with fcgid-enabled virtual domains, but it is quite helpful to optimize system resources and prevent traffic surges on one site from affecting overall server performance. Joomla and PHPbb have code that is pre-optimized w… 15, 0, 1, 0 and 7627.84

Tuning Apache and MySQL for Best Performance in a Shared Virtual Hosting Environment

…with max_connections set slightly higher than Apache’s maxclients. If you are running database caching via APC, you may lower max_connections, because APC will serve the busiest queries directly from cache. Take Time to Get a Realistic Assessment of MySQL Performance If you have a PHP opcode and database caching strategy (such as APC) implemented on your web server and for your PHP script packages, you will be able to lower maxconnections,… 16, 0, 1, 0 and 2101.56

APC Cache Considerations for Virtual Hosting Environments

APC cache does not work well in a virtual hosting environment unless PHP is running as FCGID, and every individual virtual host has a unique PHP.ini and a unique fcgiwrapper. This is not the case with many virtual hosting environments because the memory and CPU requirements are too great. I suggest using Virtualmin for a shared hosting environment with APC cache, because it does allow to set php.ini and fcgiwrapper for every individual virtual h… 2, 0, 0, 0 and 1336.17

Apache config for Worker MPM vs Prefork MPM

Some installations of Apache will have been compiled to work with either Prefork or Worker MPM, but most by default are compiled only to work with Prefork. Changing to Worker MPM may allow your server to handle much higher traffic, more user sessions, with less RAM use. Your site or server will not scale well if it is running Prefork MPM. Worker is a bit more difficult to set up properly, and has some restrictions regarding functionality of PHP… 1, 0, 1, 0 and 90.81
