this is tutorial from:

i have added just few small things to it.

- Run SSH console

Code:

cd /usr/src
wget http://sysoev.ru/nginx/nginx-0.7.63.tar.gz
wget http://stderr.net/apache/rpaf/download/mod_rpaf-0.6.tar.gz
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.9.tar.gz
tar xvzf mod_rpaf-0.6.tar.gz
cd mod_rpaf-0.6
/usr/local/apache/bin/apxs -i -c -n mod_rpaf-2.0.so mod_rpaf-2.0.c
cd /usr/src
tar xvzf pcre-7.9.tar.gz
cd pcre-7.9
./configure
make
make install
cd /usr/src
tar xvzf nginx-0.7.63.tar.gz
cd nginx-0.7.63
./configure --with-http_ssl_module --with-http_realip_module --with-http_dav_module --with-http_flv_module --with-http_gzip_static_module
make
make install

-Login to WHM and look for the following route:

Main >> Service Configuration >> Apache Setup > Include Editor > Pre Main Include

- Add the following configuration and save, LIST_OF_YOUR_IPS changing the IP you occupy in your site:

Code:

LoadModule rpaf_module modules/mod_rpaf-2.0.so
RPAFenable On
# Enable reverse proxy add forward
RPAFproxy_ips 127.0.0.1 LIST_OF_YOUR_IPS
# which ips are forwarding requests to us
RPAFsethostname On
# let rpaf update vhost settings
# allows to have the same hostnames as in the "real"
# configuration for the forwarding Apache
RPAFheader X-Real-IP
# Allows you to change which header mod_rpaf looks
# for when trying to find the ip the that is forwarding
# our requests

go to whm > tweak settings and change the apache port from 80 to 81 (find 0.0.0.0:80 and change it to 0.0.0.0.:81)

- Run SSH console

Code:

/usr/local/cpanel/whostmgr/bin/whostmgr2 --updatetweaksettings
/scripts/rebuildhttpdconf
httpd restart

Code:

nano nginx.sh

and add this code to it:

Code:

- save the file and chmod and run it:

Code:

chmod 755 nginx.sh
./nginx.sh

-Check the configuration

Code:

/usr/local/nginx/sbin/nginx -t

-Start nginx

Code:

/usr/local/nginx/sbin/nginx

- create init script [Only registered and activated users can see links. Click Here To Register...]

Code:

nano /etc/init.d/nginx

put this code into the file

Code:

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemin
# Taken from http://www.hikaro.com
# chkconfig:   - 85 15

        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2
esac

save the code and execute

Code:

chmod +x /etc/init.d/nginx

make it start when the server run

Code:

/sbin/chkconfig nginx on

to check it

Code:

/sbin/chkconfig --list nginx

check the function if it works

Code:

service nginx start
service nginx stop
service nginx restart
service nginx reload
service nginx configtest
service nginx status

Done!

is it better than normal apache & normal nignx?
will it make website faster ?
will it reduce server load ?
