Configure the VIP

You must select and assign a virtual IP address (VIP) that can freely float between cluster nodes.

This configuration creates vip, a virtual IP address for use by the API node (10.0.0.11):

For crmsh:

primitive vip ocf:heartbeat:IPaddr2 \
  params ip="10.0.0.11" cidr_netmask="24" op monitor interval="30s"

For pcs:

# pcs resource create vip ocf:heartbeat:IPaddr2 \
  params ip="10.0.0.11" cidr_netmask="24" op monitor interval="30s"
