Set a Unique Hostname for the Data Collector Host

Set a unique hostname for the computer where you plan to install Data Collector.

Follow these steps:

1. As the root user, log in to the computer where you are going to install Data Collector and verify the unique hostname on the computer.

   The hostname for the computer must be associated with the IP address and not the loopback address of 127.0.0.1.

2. Verify that the following lines appear in the /etc/hosts file on the computer:

   Do not remove the following line, or various programs
   # that require network functionality will fail.
   127.0.0.1 localhost.localdomain localhost
   ::1 localhost6.localdomain6 localhost6
   IP address of your host YourHostName YourHostName.ca.com
   

3. If the hostname required any changes, type the following command after you make the changes:

   service network restart
   

   The /etc/hosts file is configured correctly.

   The unique host name is set.
