Upgrade Script Examples (Linux)
This section provides notes on implementation and execution of an upgrade script, and also presents a couple of script samples.
Implementation and Executions Notes
- To avoid being prompted for password each time you connect via SSH to the servers where Plesk should be installed, place your public key to the list of authorized keys of a user on whose behalf the script is run on each server (see SSH documentation for details on the procedure).
- If you have a local mirror of the Plesk updates server (as described in the chapter Appendix C: Mirroring Plesk updates Server), use the following option:
--source <mirror URL>
This script upgrades Plesk installed on the specified servers to the latest available version.
#!/bin/sh SERVERS_LIST="node1.example.com node2.example.com" for current_server in $SERVERS_LIST; do ssh -f root@$current_server 'plesk installer --select-release-latest --upgrade-installed-components --notify-email firstname.lastname@example.org' done
