DirectAdmin

Today, I got a problem with one of my website. Suddenly, I could access my website using Nginx but all themes were gone. I, then, switched back to Apache. It became worse. I can't access my website at all. The error when access my website using Apache is below :

1. Download RPMForge Package. Check your system with uname -a command to get the suitable package. Below is the current one I got :

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm

Yesterday, I've tried to setup Nginx as a Reverse Proxy for Apache - Worker MPM base webserver. I found that it doesn't help my server performance as I expected. So, I decided to try to set up Nginx to be a Webserver to see if Nginx can give me a better performance or not.

When you do a reverse proxy in which Nginx will be the one who listen the traffic and forward anything needs to be process through PHP to Apache. With this, Apache will always receive an IP from Nginx server (or I should say localhost / 127.0.0.1 / local IP), not the real IP that user uses. In order to let Apache knows what is real user IP, we need to install mod_rpaf.

Just copy and paste code below into SSH :

I try to use Nginx as a reverse proxy to see if there is any improvement over Apache Worker MPM or not. I found an instruction from DirectAdmin webboard but it's quite old. So, I just tried to follow their steps and do some modification to match what I have read. Below is what I did

1. You need to compile Nginx. Nginx version 0.8.54 is the lastest stable release as of today. So, just copy and paste below code into your SSH

I have read about mod_fastcgi_handler which I think it will help me to write less code to work on PHP-FPM. Checked their website, even they say it's beta quality and there are a couple bugs. I still think I should try it. So, below is what I did to replace mod_fastcgi with mod_fastcgi_handler.

1. Put the command below into the SSH.

This guide [ Run Apache with "mod_fcgid on PHP 5.2 / 5.3" and "mod_fastcgi + PHP-FPM on PHP 5.3" on the same server in different Virtualhosts ] has 3 parts altogether. So, you may need to take a look at 2 other parts as well :

1. [HOW-TO] DirectAdmin with mod_fcgid
2. [HOW-TO] Enable and setup PHP-FPM in DirectAdmin (PHP 5.3)

I've heard about PHP-FPM about a month ago from DirectAdmin webboard. Then, a few weeks ago, I had a couple websites that I need to make it run faster. After tried to do many things with it like ... to use mod_fcgid / XCache / Memcached, I feel like there was something in XCache since "Page execution time" is quite high. Then, I remember that I've read from many websites that XCache doesn't really work with mod_fcgid. From the technical point, all of them explained it clearly to understand.

All steps below should be done with a new clean install of DirectAdmin. It is possible to make it work on the server that already have users on it. I did that and it works perfectly fine. However, the steps will be a bit different and it won't work if you just follow instruction below.

1. Copy and paste below command into your SSH

For some reason, under CentOS, Custombuild in DirectAdmin use "MySQL - Generic Linux (glibc 2.3) (x86, 64-bit) RPM file" instead of MySQL RPM files for Redhat. The different for these 2 packages are that, RPM for Redhat contain "ha_innodb_plugin.so" but not in Generic RPM package.

Compare files in Plugin folder on two different RPM.
