Prerequisites

Before connecting to the LKWMC, the REST API server must be running on every node in the LifeKeeper cluster, and the GUI server must be running on the node that the client will connect to.

The GUI server may be running on multiple nodes in the cluster at the same time, but the use of concurrent GUI sessions to perform multiple simultaneous administrative operations is not supported.

The REST API server and GUI server processes are managed by the lifekeeper-api and lifekeeper-wmc systemd services, respectively. The status of each service may be obtained using the systemctl status command:

[root@node1 ~]# systemctl status lifekeeper-api
● lifekeeper-api.service - SIOS LifeKeeper REST API Server Loaded: loaded (/usr/lib/systemd/system/lifekeeper-api.service; static; vendor preset: disabled)
Active: active (running)

[root@node1 ~]# systemctl status lifekeeper-wmc
● lifekeeper-wmc.service - LifeKeeper Web Management Console Service Loaded: loaded (/usr/lib/systemd/system/lifekeeper-wmc.service; enabled; vendor preset: disabled)
Active: active (running)
