I want to have OpenLiteSpeed server on a server with DirectAdmin. How can I do it?


OpenLiteSpeed is the Open Source edition of LiteSpeed Web Server Enterprise with fewer processes, less overhead, and enormous scalability in comparison with other popular web-servers. 

OpenLiteSpeed is mod_rewrite compatible, with no new syntax to learn. Built-in full-page cache module is highly-customizable and efficient for an exceptional user experience.

Experience a measurable performance boost with OpenLiteSpeed and LSCache for WordPress.

OLS comes with a built-in WebAdmin GUI as shown below:

OpenLiteSpeed is the Open Source edition of LiteSpeed Web Server Enterprise.

So if you decided to use it, here is a guide on how to install it.

Installation Guide

At the moment of writing this article CustomBuild 2.0 does not support OpenLiteSpeed yet, support is coming soon though! They announced DirectAdmin 1.56.2 1.56.4 will support it.

Anyway here is how can you get it installed with the help of CustomBuild once they introduce the full support of it.

On a CentOS server, first run this as root (it's a requirement): 

yum -y install udns-devel GeoIP-devel

Then do the following (commands were discovered through reading code of CustomBuild script rev: 2033 available at the moment):

cd /usr/local/directadmin/custombuild
./build update && ./build clean
./build set webserver openlitespeed

for i in 1 2 3 4; do ./build set php${i}_mode php-fpm; done;

./build openlitespeed
./build php
./build rewrite_confs

That's it for now.
