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 6979.18

I was recently searching for a form template that uses Twitter’s Bootstrap framework. PFBC, the PHP Form Builder Class, was recently refactored with Bootstrap, and it also supports validation and reCAPTCHA. PFBC does not include a form handler, but it does take the difficult and redundant work out of creating self-validating forms. Adding an auto-mailer to PFBC is very simple, however. You just need a simple PHP if/else and all is well. If… 11, 0, 0, 0 and 1193.46
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 713.48

Search no longer works, nor does pagination, etc. Plus, it’s out of date and vulnerable to an XSS exploit. I have solved this by changing to the EPEL repo, which maintains the latest version of phpMyAdmin. This post will teach you how to install phpMyAdmin on CentOS, Amazon Linux, or Redhat.

…ted 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 “solutions” had actually made the problems worse, resulting in an “own goal” that brought down the server… 0, 0, 1, 0 and 389.17
