I've set up Kerberos in my workplace running on Centos 6 boxes, and successfully propagated the master server database to the slave and also set up a cron job to update it automatically every 5 minutes.
I was wondering if there was a way to automate the process of switching the Master to the Slave in case the Master unexpectedly goes down?.
The only information I can find is having to manually switch the CNAMEs of the two servers.
