This allows you to set a recovery password that you can use to reset the passwords for your regular adminsirators if their passwords are forgotten (or if they rely on SSO which is broken for some reason).

cp /opt/atlassian/jira-servicedesk/current/bin/setenv.sh /opt/atlassian/jira-servicedesk/current/bin/setenv.shO

vi /opt/atlassian/jira-servicedesk/current/bin/setenv.sh

Add the following argument to the JVM_SUPPORT_RECOMMENDED_ARGS parameter...

-Datlassian.recovery.password=<your-password>

For example...

JVM_SUPPORT_RECOMMENDED_ARGS="-XX:+ExplicitGCInvokesConcurrent -XX:ReservedCodeCacheSize=512M -Datlassian.recovery.password=mypassword"

Restart Jira

systemctl restart jira

Repeat for all nodes in your cluster.
