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… 10, 0, 2, 0 and 2313.86

APC Cache Considerations for Virtual Hosting Environments

…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 host, and so to set an individual configuration for APC per virtual server. However with 200+ v… 6, 0, 2, 0 and 1364.91

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

…sible to give a configuration which will cover all applications. Firewall Unnecessary Traffic from Affecting the Server Before you begin performance tuning, please consider using a stateful packet inspection (SPI) firewall & login failure daemon (LFD) for your server: ConfigServer Firewall is an excellent free firewall & LFD. This will help prevent brute force probes, port flooding, DDOS, etc. If you have 600 virtual hosts running on a se… 10, 0, 1, 0 and 1364.91

WordPress with W3 Total Cache on Nginx with APC (Virtualmin)

Virtualmin now includes support for Nginx web server. I deploy many WordPress sites with W3 Total Cache and APC Alternative PHP Cache, so I was very interested to see how Nginx performance compares to Apache for WordPress, and whether APC and W3TC would play nice with Nginx. I prefer to install WordPress in public_html/wordpress for ease of development, compatibility with other scripts, etc. Accordingly, the suggested configuration is for WordPr… 8, 0, 0, 0 and 1091.93

Apache config for Worker MPM vs Prefork MPM

…ecompile Apache and PHP, then you should do more research. Recompiling is not a trivial process. I found that my server had much better memory usage under Worker 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 pe… 6, 0, 1, 0 and 753.95

Apache and MySql Performance Tuning for High Traffic WordPress Website on Cpanel

…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 Cpanel server. Haphazardly implementing randomly suggested “solutionsR… 9, 0, 1, 0 and 506.96
