How to accelerate cPanel web hosting server with nginx?

You can find  a lot of answers  through the Internet, like this:

cPanel forums
24x7servermanagement

All methods  are good, but there is one big problem with script  (postwwwacct) which was suggested by somebody. It is useless if you are using Addon and Sub domains. This script set wrong homedir for sub- and addon- domains in config.

I wouldn’t rewrite all solution, you can find it easily. But I wrote my own script which generate vhosts.cfg

I think it  will put on in right place.

You can get it simply:

wget http://lanselot.me/scripts/postwwwacct

In variable VHOSTFILE set destination of your vhost config file.

#!/bin/bash
#Lanselot 2011
VHOSTFILE=”/opt/nginx/conf/vhosts.cfg”
/bin/cp /dev/null $VHOSTFILE

function writevhosts {
for DOMAIN in $@ ; do
ROOT=`cat /var/cpanel/userdata/$USER/”$DOMAIN” | grep documentroot | awk ‘{print $2}’`
ALIASES=`cat /var/cpanel/userdata/$USER/”$DOMAIN” | grep serveralias | sed “s/serveralias: //g” | sed “s/www\.\*\.$DOMAIN//g”`
cat >> “$VHOSTFILE” < server {
access_log /dev/null;
error_log /dev/null;
listen 80;
server_name $DOMAIN $ALIASES;
