4. Click Save and wait for the installation to complete.

The installation may take several minutes depending on the server performance and the number of sites. During the installation of the web server, the sites will be unavailable.

Changing the web server

Some web server settings are incompatible with each other. If a web server is already installed on the ispmanager server and some sites are created, we recommend creating a backup copy of the site configuration files before switching to another web server. This will allow you to return the sites to their original state if they do not work correctly with the new web server.

When switching to another web server, issues may occur if the site:

• Uses a .htaccess file. Nginx does not use .htaccess, and OpenLiteSpeed ​​will ignore all directives except those described in the Apache mod_rewrite module documentation.
• Uses custom configuration file templates. The templates will have to be re-created.
• Uses configuration files that were altered manually. The changes will need to be adapted to the new web server and re-entered.

For more information on changes when switching to a specific web server, please see articles about web servers:

• Apache
• Nginx
• OpenLiteSpeed
