Nginx with CPanel

http://cpxstack.sysally.net/

Cpxstack is a plugin to cPanel that completely replaces Apache with nginx (other plugins keeps apache and configure nginx as a reverse proxy).

To install cpxstack, you need Incron. For this you need to enable the EPEL repository (see previous article for this).

You also need to install php-devel. Cpanel prevents installing any php related packages through an "exclude" entry in yum.conf. Open yum.conf and remove "php*".

After upgrading to the latest stable PHP version, you should enable the Remi repository and the php55 remi repository. You can now install php-devel.

You can run the cpxstack.sh script as per instructions here: http://cpxstack.sysally.net/documentation.htm

For incron and php-devel you can alternatively directly run the cpxstack.sh script to see if it installs these packages automatically.

After the script has run, you should go to WHM, when you click on the cpxstack icon in the sidebar, it will ask you to change a setting in the Tweak Settings area.
You also need to go to cPanel and manually enable nginx for your site. Also in WHM change the default number of worker processes to a lower number (default is 15).

cPanel: Install php-devel

CPanel disables installation of php related packages using yum. To enable it:

nano /etc/yum.conf

Remove php* from the "exclude" line.

EPEL repositories for Fedora and Cent OS

Certain applications such as incron can't be found in the default repositories of Cent OS. To get this software, you need to enable the EPEL (Extra Packages for Enterprise Linux) repository:
