About this task
To manually map hostnames to IP addresses without a DNS, you need
to edit the /etc/hosts file on the planned primary EPM server so that it includes an entry for each of the
servers in the Experience Portal system.
Procedure
- Log into Linux on the
planned primary EPM server.
- Back up the original
file prior to editing it by entering the cp /etc/hosts /etc/hosts.bak command.
- With the ASCII text
editor of your choice, open the /etc/hosts file.
- Make sure that the
first line contains
127.0.0.1 localhost
localhost.localdomain, with the IP address and hostnames
separated by spaces or tabs. - Create a new line for
each server in the Experience Portal system using the format
IP_address hostname1
hostname2... where:
IP_address is the IP address of a server in the Experience Portal system and hostname1 hostname2... is one or more hostnames, separated by tabs or spaces,
to associate with the IP address.
You should have one entry for each of the following components
used in your Experience Portal system:
All MPP servers.
The auxiliary EPM server, if one is planned for this Experience Portal system.
All PBX servers.
All application
servers.
All speech servers.
Communication Manager.
Avaya Aura® Session Manager.
- Save and close the file.
Example
The following shows a properly-formatted /etc/hosts file with two MPP servers:
127.0.0.1 localhost localhost.localdomain #Required first line
10.10.10.120 primary-epm primary-epm.samplecompany.com #Primary EPM server IP address
10.10.10.121 first-mpp first-mpp.samplecompany.com #First MPP server
10.10.10.122 second-mpp second-mpp.samplecompany.com #Second MPP server
