Modify the /etc/hosts file to ensure that the loopback address is specified.

1. Navigate to the /etc directory and make a backup of the hosts file
2. Edit the hosts file and if the loopback address is commented, then uncomment it by removing the # and save the file.


3. If the loopback address is not in the hosts file, add it to the beginning of the file but at the end of the initial comments section, as in the following example:
# hosts This file describes a number of hostname-to-address
# mappings for the TCP/IP subsystem. It is mostly
# used at boot time, when no name servers are running.
# On small systems, this file can be used instead of a
# “named” name server.
# Syntax:
# IP-Address Full-Qualified-Hostname Short-Hostname
# localhost
4. Save the hosts file
5. Reboot the server.
6. Upgrade Sentinel.


The loopback address is either not specified or commented in the /etc/hosts file.
