If you want to be able to upgrade to a Plesk version other than the latest stable release, you can upgrade using the interactive console. To begin, connect to the server via SSH and run the following commands:

  1. wget https://autoinstall.plesk.com/plesk-installer
  2. chmod +x plesk-installer
  3. ./plesk-installer

This will launch the console in the shell. If you want to upgrade to the latest preview of the upcoming release, run the installer with the --tier testing option:

./plesk-installer --tier testing

If you want to change the directory to which the installer will download files (./parallels by default), run the installer with the --target <path to the desired directory> option:

./plesk-installer --target /tmp/plesk_download

By default, they are downloaded from Plesk servers. However, you may want to install from a different server (for example, if you have set up a local mirror), or from the local disk (if you have downloaded the installation files beforehand). To install from a different source, run the installer with the --source <URL or local path> option:

./plesk-installer --source http://local.example.com/plesk_download
./plesk-installer --source /tmp/plesk_download

If you are upgrading Plesk on a server behind an HTTP proxy, you can configure the proxy server address by adding the --proxy-host <IP address or hostname> and --proxy-port <port> options. If authentication is required, you can set the username and password via the --proxy-user <username> and --proxy-password <password> options:

./plesk-installer --proxy-host http://proxy.example.com --proxy-port 8080 --proxy-user john_doe --proxy-password MySecurePass#123

If you prefer to use a graphical interface during the upgrade, see the Upgrading Plesk for Linux Using Installer GUI topic.
