| This guide assumes you set up the four appliance following the instructions in the Appliance Installation guide. For easy failover of the application in case of a database failover, you must assign a virtual IP address for the database servers. This will mean that you can change the primary DB server without changing the configuration on the application servers. There are many ways in Linux to configure automatic failover of the VIP, but this guide will configure the DB servers requiring manual failover. This is often preferred in our scenario of master - slave replication. | This guide assumes you set up the four appliances following the instructions in the Appliance Installation guide.
