Hello,
Today We will learn how to install litespeed webserver on the cpanel
Step 1: Install LiteSpeed WHM plugin
Run the following commands from ssh as root
- Code:
cd /usr/src
wget http://www.litespeedtech.com/packages/cpanel/lsws_whm_plugin_install.sh
sh ./lsws_whm_plugin_install.sh
rm -f lsws_whm_plugin_install.sh
Step 2: Install LiteSpeed Speed Web Server from within WHM
click “LiteSpeed Web Server Plugin for WHM” in “Plugins” section of WHM.
click “Install LiteSpeed Web Server”
Fill in the form to specify your:
serial number/license key above
LiteSpeed target installation directory
Port Offset ( set to 0 to replace Apache otherwise set a number like “2000” to try LiteSpeed on port 2080 )
Whether to enable PHP SuEXEC
Assign user name and password for LWSW web admin console
Your email address as the Administrators email.
Click “Next” to install LiteSpeed
If you set Port Offset to “0”, it may stop Apache and start LiteSpeed after a successful installation, you may want to switch back to Apache temporarily as we still need to build PHP binary for LiteSpeed.
Step 3: Build matching PHP binary
There is a pre-built PHP 4 binary coming with LSWS, however, you should build your own PHP binary using matching configuration options used by Apache mod_php.
If LiteSpeed is running, you should switch back to Apache temporarily by clicking “switch to Apache” link. Then, click “Build Matching PHP binary” link. It is going take a while.
Step 4: Start LiteSpeed again
Just click “Restart LiteSpeed” Then you can verify if everything works as expected. It should! 
If “Port Offset” is set to non-zero, you can now replace Apache with LiteSpeed Web Server. Just click “Switch to LiteSpeed”.
That’s it. DONE
WARNING: Do NOT uncheck “httpd” service under WHM service manager, otherwise WHM wont restart LiteSpeed automatically when configuration has been changed.
Thank you . Hope the tutorial was easy to learn
