About the Pacemaker Web User Interface

The Pacemaker service provides a web user interface tool (web UI) that enables you to configure and manage clusters in graphical mode. Use this tool as an alternative to typing pcs commands to perform those tasks.

This chapter assumes that you have completed the tasks that are described in Installing and Enabling the Pacemaker and Corosync Service and that the nodes have been authenticated for the hacluster user.

For information about authentication and configuring hacluster credentials, see Step 1 of Creating the Cluster.

To access the web UI, log in as user hacluster at https://node:2224, where node refers to a node authenticated for hacluster. Specify the node either by its node name or IP address.

Note:

The rest of this chapter assumes that you have configured resolvable names for all the nodes.

After you log in, the home page's Manage Clusters page is displayed. This page lists clusters that are under the web UI's management.

Figure 7-1 Manage Clusters


The image partially shows the Manage Clusters page where an administrator can remove, add existing clusters, destroy clusters, or create new ones. Clusters that are created and managed by the web UI would be listed on the page, and corresponding information about a selected cluster would also be displayed, such as its nodes, and so on.
