How to install Plesk updates?
Note: For upgrading Plesk to the next release, see this KB article.
Note: During Plesk update:
- Plesk may go offline for several minutes, if updates require a Plesk restart
- Websites will stay online
If a service component is going to be updated, its service will be restarted.
Note: Make sure that port 8447 is opened in a firewall. If it is closed and cannot be opened for some reason, use the command-line instructions.
In Plesk, go to Tools & Settings and click Updates and Upgrades.
On the Updates and Upgrades page, click Update Components.
Click Continue to begin the update procedure.
Connect to a Plesk server via SSH (Linux) / RDP (Windows Server).
Run Plesk Installer Update (on Windows Server, start a command prompt as an Administrator):
MYSQL_LIN: plesk installer update
By default, Plesk installs updates automatically by means of the Plesk daily task (executed every night), if the option Automatically install Plesk updates is enabled at Tools & Settings > Update Settings.
To find out what Plesk update is currently installed on the system, go to the Home page > System Overview.
Alternatively, execute the following command in a command-line interface:
MYSQL_LIN: plesk version
