This chapter provides an overview of configuring a Red Hat High Availability cluster with the
2.1. pcsd Web UI Setup
To set up your system to use the
pcsdWeb UI to configure a cluster, use the following procedure.
- Install the Pacemaker configuration tools, as described in Section 1.2, “Installing Pacemaker configuration tools”.
- On each node that will be part of the cluster, use the
passwdcommand to set the password for user
hacluster, using the same password on each node.
- Start and enable the
pcsddaemon on each node:
systemctl start pcsd.service#
systemctl enable pcsd.service
- On one node of the cluster, authenticate the nodes that will constitute the cluster with the following command. After executing this command, you will be prompted for a
pcs cluster auth node1 node2 ... nodeN
- On any system, open a browser to the following URL, specifying one of the nodes you have authorized (note that this uses the
httpsprotocol). This brings up the
pcsdWeb UI login screen.
- Log in as user
hacluster. This brings up the Manage Clusters page as shown in Figure 2.1, “Manage Clusters page”.
