VIP

VIP is an abbreviation for Virtual IP. On other systems it is also called floating IP. A virtual IP address is an IP address that does not correspond to an actual physical network interface (port). Uses for VIPs include fault-tolerance, and mobility [Wikipedia].

VIP overview

The VIP overview of a new (= empty) Ops Center looks as follows:

Add or edit VIP

When you click the Add VIP button you get a mask where you can specify a VIP:

In the mask to add or edit a VIP you have to enter:

• The replication cluster the VIP belongs to.
• The IP address itself of the VIP.
• A DNS service name if you have defined one for this VIP. DNS names make your application independent from the IP address (VIP).
• The physical interface where the VIP should be located. This must be the same physical interface on all nodes.
• The alias number of the physical interface if you use old style configuration (ifconfig).
• The VIP configuration style (old = ifconfig, new = ip addr).
• The primary location of the VIP.
• The secondary location of the VIP.
• How the failover should be done:
  • Failover only when sync - Only failover VIP if primary and secondary are in sync (Seconds_Behind_Master = 0)
  • Start VIP only when sync - Wait with starting VIP on secondary until secondary is Seconds_Behind_Master = 0.
