Configure high available mysql inside my instances

asked 2014-07-15 20:58:16 -0500 gravatar image


I am planning to set-up high availability for my MySQL server using corosync and pacemaker via DRBD . For this, I need to set up a VIP (virtual IP ) in my instances. How can I configure a VIP in my openstack instance?

I have done this in Oracle ASM. There's nothing special in using VIP, you just need to reserve the IP from nova that will be use as VIP and make sure you have allowed the necessary ports in security group.

Hope that helps..

Please can you give more details? I am trying to do something similar: I have a VIP managed by pacemaker on my cluster of Openstack instances (using the IPaddr2 resource), which can't be pinged. Running nova fixed-ip-reserve <ip> just gives "ERROR: Fixed IP <ip> not found (HTTP 404)".
