Generally the VRRP protocol take care that one of nodes is master in pool of the servers where the keepalived is running. vrrp_instance VI_1 {state MASTER. Each keepalived instance can keep track of multiple VRRP clusters, where with some clusters the node will be master but in other clusters merely a backup for a different VIP. To avoid having to frequently run a track_script to monitor the existance of processes (often haproxy or nginx), vrrp_track_process can monitor whether other processes are running.
