Edit the Host File

  1. Using a text editor, open the hosts file on every host in your cluster. For example:

    vi /etc/hosts

  2. Add a line for each host in your cluster. The line should consist of the IP address and the FQDN. For example: <fully.qualified.domain.name>


    Do not remove the following two lines from your hosts file. Removing or editing the following lines may cause various programs that require network functionality to fail. localhost.localdomain localhost

    ::1 localhost6.localdomain6 localhost6
