Modifying the GUI Server Port

By default, the GUI server listens for client connections on TCP port 5110. If necessary (e.g., if there is a conflict caused by a different process listening on the same port), this port number may be changed.

To change the port number, follow these steps:

1. On each LifeKeeper cluster node, open the /etc/default/LifeKeeper file using a text editor:

# vi /etc/default/LifeKeeper

and add an entry of the following form (or modify the entry if it already exists):

WEBUI_PORT=<GUI Server TCP Port>

For example, to set the GUI server port to TCP port 8000, the following entry would be added:

WEBUI_PORT=8000

*It is important to make this modification to /etc/default/LifeKeeper on all nodes in the LifeKeeper cluster.

2. In order to apply the changes, the systemd service that manages the GUI server (lifekeeper-wmc.service) must be restarted on all LifeKeeper nodes where it is running:

# systemctl restart lifekeeper-wmc
