FAQ


What exactly does this script do?

First, the script will ask for your input on several options, depending on your environment. Then, it will install LiteSpeed. If you are running cPanel or Plesk, you'll be offered the option of running LiteSpeed alongside your current web server, so you can switch between them, with no downtime. Otherwise, LiteSpeed will replace your current server.

Will this work with my control panel?

We have tested this installer with cPanel, Plesk, DirectAdmin, Hsphere, Interworx, Lxadmin, and ISPManager.

Will this work with my operating system?

LiteSpeed should work with any modern Linux distribution.

Automation


In most situations, running the installer script manually is sufficient. However, it is possible to automate the process for bulk provisioning. If you want to include the installer in your own scripts, you can provide a `lsws.options` file in the same folder as the installer. This will keep the installer from asking for user input when it runs. We've included some sample option files for popular control panels below.

# This will register the server using the serial number specified and retrieve a license key. Inputting TRIAL will cause a trial key to be requested and installed.

# Available values are 0 (disable), 1 (enable), and 2 (user home directory only). Default value is 2.

# Controls the Apache port offset. This allows you to run LiteSpeed in parallel with Apache to test it out. For example, if you set port offset to 1000, Apache will continue running on port 80 and LiteSpeed will run on port 1080. If port_offset is set to 0, LiteSpeed will be installed and set to use the same port Apache is currently using, but will not be automatically started after installation unless set to do so in a later parameter. When you are ready to replace Apache with LSWS as your main web server, simply stop Apache and start LiteSpeed (or use the Switch to LiteSpeed button in the WHM plugin). Default value is 1000.
