When the daemon running at MASTER device detects failure of at least one described features it
immediately automatically switches cluster's IP assignment to the BACKUP device (node) providing
continuous usage of the SMSEagle HA-cluster for the user.
HOW TO CONFIGURE FAILOVER (HA-CLUSTER):
Failover cluster can be easily configured using web-gui. Configuration can be done in menu “Settings” > tab
“Failover”. For each device in failover cluster:
• enter virtual IP address in the field “Virtual IP Address”
• set “Enable Failover cluster” to “Yes”.
Save configuration. Reboot each device after saving.
Screenshot from “General settings-Failover”
A device that boots first becomes MASTER in failover cluster, second and next devices are BACKUPs. In the
cluster you have one MASTER device and at least one BACKUP device (depending of number of nodes). The
HA-cluster will automatically switch between physical devices depending on the node health-check.
After correct configuration of the HA-cluster you should access the cluster via its Virtual IP address.
Alternatively configuration may be also made using Linux command line:
