Furthermore, we can configure the LVS by using Keeplived and ipvsadm commands. Keepalived informs the LVS about the server states periodically for automatic load distribution configuration. For example, if Keepalived detects the accidental failure of servers, the LVS changes the weight of the load distribution to the servers to 0. Moreover, it also senses the participation of new servers, which is useful for energy-proportional control because the number of active servers varies frequently.
