Modifying the GUI Server Port

!Due to a defect of LKWMC v1.1.0 and LKWMC v1.2.0, the GUI Server Port cannot be changed in /etc/default/LifeKeeper.
As a workaround, use the following command for step 1 below.
# systemctl set-environment WEBUI_PORT=<TCP port number of the GUI server>

*This documentation section describes the LifeKeeper Web Management Console (LKWMC). Refer to the LifeKeeper Web Management Console for an overview.

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
