Pre-upgrade/Post-upgrade scripts

The pre-upgrade and post-upgrade script feature allows you to execute a user defined script before and after a software system upgrade.

The scripts run only when there are packages to install, they will not run when “showing” packages that could be installed.

During a real upgrade, the router will try and download the scripts from the same location as is configured by the Change Repository Server page. The router will attempt to download a file named “pre-upgrade” and execute it before the upgrade starts. After the upgrade completes (including webmin) the router will attempt to download a file named “post-upgrade” and execute it.

The scripts start with #!/bin/bash or #!/usr/bin/perl and be designed to produce consistent results in the event they are subsequent run a second time. It is possible that the upgrade can be interrupted after the preupgrade script runs, and re-started at a later date.

The result of running the pre-upgrade script is included in the upgrade output. If ran through the automatic upgrade, the scripts output can be viewed by through the “View Log File of Last Upgrade” button on the Software Upgrade System page.

Example of a post-upgrade script: The following post-upgrade script will send an email notification when upgrade completes (assuming ssmtp is configured properly).

#!/bin/bash

echo "Subject: Software upgrade for Release rr1.9.0 on `hostname` completed" > /tmp/mail

echo "To: controlcenter@ruggedcom.com" >> /tmp/mail

echo "Software upgrade for Release rr1.9.0 on `hostname` completed at `date`" >> /tmp/mail echo >> /tmp/mail

cat /tmp/mail ssmtp controlcenter@ruggedcom.com rm ­f /tmp/mail
