In this article, we'll show you how to install Plesk on a Linux VPS.

To set up Plesk for Linux with the default configuration, follow the steps below:

Enabling the Required Ports in the Cloud Panel

To install Plesk, incoming traffic must be allowed on TCP 8443 and TCP 8447 ports. These ports are enabled by default in the firewall when you purchase a VPS. If you want to use other Plesk services, you need to create additional rules in the firewall to enable these ports.

A list of ports and protocols used by Plesk can be found here:

To create a new rule in the firewall, do the following:

  • Log in to your IONOS account.
  • In the title bar, click Menu > Server & Cloud. If you have multiple contracts, select the desired Server & Cloud contract.

  • In the navigation bar on the left, click Network > Firewall Policies.

  • Select the firewall.

 

  • Create a new rule in the Configuration area. To do this, enter the desired port.

  • Click the green check mark to add the rule.
