So, you went through the one time setup and all is working. But now there is an update. What do you do?
First, get the update of course. It will be a file called "root.war". Download it to your server, to let's say /tmp/root.war.
Now perform the following steps:
- /etc/init.d/jetty stop
- mv /usr/local/jetty/webapps/root.war somewhere else as a backup in case Things Go Wrong
- cp /tmp/root.war /usr/local/jetty/webapps/root.war
- /etc/init.d/jetty start
- /etc/init.d/apache2 restart
Step 5 forces Apache to reconnect right away to Jetty - it may take 5-010 seconds otherwise. So if you do 5) really depends on the load/maintenance window etc. And that's all it takes to upgrade!
