122 Chapter 10. Configuring the LVS Routers with Piranha Configuration Tool
Redundant server private IP
Enter the backup node’s private real IP address in this text field.
If you do not see the field called
Redundant server private IP , go back to the
GLOBAL SETTINGS
panel and enter a
Primary server private IP
address and
click
ACCEPT
.
The rest of the panel is devoted to configuring the heartbeat channel, which is used by the
backup node to monitor the primary node for failure.
Heartbeat Interval (seconds)
This field sets the number of seconds between heartbeats — the interval that the
backup node will check the functional status of the primary LVS node.
Assume dead after (seconds)
If the primary LVS node does not respond after this number of seconds, then the
backup LVS router node will initiate failover.
Heartbeat runs on port
This field sets the port at which the heartbeat communicates with the primary LVS
node. The default is set to 539 if this field is left blank.
Warning
Remember to click the ACCEPT button after making any changes in this panel to make
sure you do not lose any changes when selecting a new panel.
10.6. VIRTUAL SERVERS
The VIRTUAL SERVERS panel displays information for each currently defined virtual
server. Each table entry shows the status of the virtual server, the server name, the virtual
IP assigned to the server, the netmask of the virtual IP, the port number to which the service
communicates, the protocol used, and the virtual device interface.
