Linux Enterprise Cluster: Build a Highly Available Cluster with Commodity Hardware and Free Software
Heartbeat uses three configuration files:
/etc/ha.d/ha.cf
Specifies how the heartbeat daemons on each system communicate with each other.
/etc/ha.d/haresources
Specifies which server should normally act as the primary server for a particular resource and which server should own the IP address that client computers will use to access the resource.
/etc/ha.d/authkeys
Specifies how the Heartbeat packets should be encrypted.
| Note | The ha in these scripts stands for high availability. (The name "haresources" is not related to bunny rabbits.) |
