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 wi… 138, 2, 6, 0 and 244.58
WordPress with W3 Total Cache on Nginx with APC (Virtualmin)
for WordPress pretty URL Permalinks The nginx Compatibility plugin has support for pretty URLs, but you must configure Nginx to use them. You should add or edit the following URL path locations to nginx.conf for your virtual domain… either by direct edit, or via URL Path Locations in Virtualmin > Services > Configure Nginx Website (see attached image…). This config is for WP installed in /public_html/wordpress, so you will need… 71, 1, 1, 0 and 120.53
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… 20, 1, 2, 0 and 37.36
Apache and MySql Performance Tuning for High Traffic Website
…ter responding to a plea for assistance in a WordPress.org support forum. Though the site was running on a dedicated server with 8GB RAM, it was crashing frequently under load. The developer tried implementing APC Alternative PHP Cache and W3 Total Cache, but these measures turned out to be incompatible with some of the custom PHP code and the software architecture of the server. Haphazardly implementing randomly suggested “solutions”… 8, 0, 1, 0 and 12.86

Apache config for Worker MPM vs Prefork MPM
however: some scripts (squirrelmail, phpmyadmin) do not work on a per-domain basis and must be run direct to the actual server process with symlinked directories. This is much more efficient but less convenient for virtual domain owners some /dev processes took on strange group permissions, getting the gid of the first user in the apache group. browser caching was not well supported… the dreaded “blank screen between page loadsR… 4, 0, 1, 0 and 7.71

Tuning Apache and MySQL for Best Performance in a Shared Virtual Hosting Environment
Web hosting has changed dramatically in the last few years. The majority of accounts are now running PHP scripts and MySQL, whereas in the past most accounts were only serving static HTML files. This presents challenges in security as well as performance tuning. It is impossible to predict whether a certain configuration will work properly for a given server, unless the hardware, software, accounts, network and traffic are identical to a previou… 4, 0, 1, 0 and 6.77
