OpenLiteSpeed doesn’t require any control panel to service the website. However, control panel such as Free CyberPanel can make your life much easier than using OLS alone since Cyberpanel will do a lot of stuff for you including shared hosting file/folder permission and much more. We strongly recommend you to install OpenLiteSpeed with Cyberpanel together especially you are new to OLS, otherwise, you will need to do a lot of stuff manually such as :what file/folder permission should be for a user? How to create a virtual host on OLS? How to do domain mapping to a virtual host? How to create and use PHP SuEXEC to make the server secure for shared hosting service? etc.
Please refer to this guide for OLS and Cyberpanel installation
