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

…o use APC and other opcode caches. Apparently, Gallery3 now also supports opcode caching. More advice: turn on apc.stat (documentation says, “not for production servers”, but W3TC requires stat polling to monitor file status, post revisions, plugin upgrades, etc.) turn off apc.optimization (experimental and unstable, may cache user session info, fubaring items which should not be cached, such as admin pages and logged-in site pages)… 2, 1, 0, 0 and 12557.21

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

…configuration is for WordPress installed in a subfolder. This info also assumes you have successfully installed APC Cache on your server, and set up a clean install of Virtualmin with Nginx as the Alternative Web Server. Switching from Apache to Nginx later is difficult, as is transferring apache virtual server backups. Best to start fresh and build from scratch. Testing the Virtualmin Nginx Modules Virtualmin does not support Nginx and Apache t… 1, 0, 0, 0 and 6044.62

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

…g scripts. The apache tuning will give you the number of maxclients, and from this you will know the appropriate beginning value for [mysqld] max_connections. Begin with max_connections set slightly higher than Apache’s maxclients.

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… 3, 0, 0, 0 and 2365.85

Varnish VCL and Config for WordPress with W3 Total Cache

I have been working on a Varnish front-end for Apache, to be used with WordPress sites. I described the architecture in Load Balancing Virtualmin WordPress Hosting Server with Varnish on AWS. I now have a configuration that seems to work for all WordPress features, including logged-out commenting. This configuration also works well with W3 Total Cache. This configuration is for Varnish on a separate server, but should also work on a single serve… 1, 0, 0, 0 and 1286.92

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

…he site will definitely see a huge amount of users. Future plans include changing the architecture of the server to simplify the background processes and implement APC Alternative PHP Cache, or a caching web server front end. Results?

Apache config for Worker MPM vs Prefork MPM

…he first user in the apache group. browser caching was not well supported… the dreaded “blank screen between page loads” occurred more frequently under Worker MPM than Prefork MPM… also login/logout was sketchy on some sites… not sure why but my guess is that sessions may not be quite persistent using Worker vs Prefork due to cookie confusion… possible that multi-threading does not track cookies well.

Install phpMyAdmin with SSL on CentOS, Amazon Linux, RedHat (Apache or NginX)

…I recently ran into a problem with the upgraded 3.5.2 phpMyAdmin package provided via the rpmforge.repo.
