Chapter 5. Identify the Virtual IP Address

For the purposes of a restoring a high availability cluster, Red Hat assumes at least three cluster nodes. For example, overcloud nodes overcloud-controller-0, overcloud-controller-1 and overcloud-controller-2: 

overcloud-controller-0.example.com 192.168.1.1
overcloud-controller-1.example.com 192.168.1.2
overcloud-controller-2.example.com 192.168.1.3

Procedure

Identify the virtual IP address that OpenStack services use to access the database.

Run the following command: 

[root@overcloud-controller-0]# grep -A1 mysql /etc/haproxy/haproxy.cfg
Copy to Clipboard Toggle word wrap

It should retrieve the virtual IP address and port. For example: 

listen mysql
  bind 192.168.1.10::3306 transparent
Copy to Clipboard Toggle word wrap

In the foregoing example, the virtual IP address is 192.168.1.10.
