I have a server set up on CentOS and I need to change the API from CGI to FCGI (Someone else set this up initially) for x-cache to work (we need this as we have a TV appearance on monday and are expecting high-load).
The server is a dedicated Dell R210 with Intel Xeon L3426 (8M Cache 1.86GHz) and 2GB RAM - but it craps out with 244 concurrent clients (through loadimpact.com).
The plan is to install nginx as a reverse proxy for apache and config apache to listen on port 81 localhost and have nginx forward requests to apache.
At the moment what is killing our processor is php rendering as we are running Joomla 1.5 and as such I want to run x-cache as an op-code cacher to RAM. But x-cache doesn't work with CGI - only FCGI and so ends my explanation as why this needs to be done.
Is this a safe change for a Joomla site?
How can this be done through CLI - we have cpanel but I hate it.
