## HeartBeat Redundant Server

HeartBeat is a High Availability Linux solution designed to provide servers with hardware redundancy. HeartBeat provides a primary/hot standby server pairing which can share a single IP address to the external world. HeartBeat continually checks its partner server over a private link. In the event of failure, HeartBeat allows the “services” it supports to become active on the standby server until the primary server recovers.

HeartBeat is used in conjunction with MV_WatchDog, which provides application level monitoring.

Detailed information on HeartBeat setup is provided in Chapter 9: HeartBeat. The installation script provided does all the setup, provided the defaults are acceptable.

Tthe Linux-HA project provides HeartBeat. For more information, see:
