Task 1. Change the host name to lowercase on each node

A distributed deployment of Service Manager Service Manager Service Portal requires each node in the cluster to have a lowercase host name. In this example, each of the nodes (one load balancer node, two application nodes, and two database nodes) must have a lowercase host name.

On each of the nodes in the cluster, perform the following operations:

  1. Run the following commands:

    # hostname
    # hostname -f
    
  2. If the host name is not in lowercase, change the host name in the following files to lowercase:

    # vi /etc/hostname
    # vi /etc/hosts
