LiteSpeed Web Server Plugin for cPanel®/WHM® in 4 Step

Run the following commands from ssh as root

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

Note: To uninstall WHM LiteSpeed plugin, run command at

/usr/local/cpanel/whostmgr/docroot/cgi/lsws/lsws_whm_plugin_uninstall.sh

1. Click “LiteSpeed Web Server Plugin for WHM” in “Plugins” section of WHM.
    
2. Click “Install LiteSpeed Web Server”
    
3. Fill in the form to sepecify
    
   • Trial license key or serial number
   • 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.
      
4. 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.

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.

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”.

Peace Out!
