This will install OpenLiteSpeed and the PHP 7.4 module for OpenLiteSpeed on your system.

During the installation process, you will be prompted to set the password for the admin user of OpenLiteSpeed. Enter a password and press <Enter> to continue.

Configuring OpenLiteSpeed

After installing OpenLiteSpeed, you need to configure the web server to use PHP 7.4.

To do this, open the /usr/local/lsws/conf/httpd_config.conf file in a text editor and find the php1_* settings. Modify the settings to match the following:

Accessing the OpenLiteSpeed Web Interface

After configuring OpenLiteSpeed, you can access the web interface of the web server by visiting the following URL in your web browser:
