1.1. How to change hostname on SLES 11 server

Assume you have configured testing environment with WebSphere Application Server V8.0 on SuSE Linux Enterprise Server 11 (SLES 11), and you want to change hostname for some reason - like use cloned VM to test CIM.

Edit /etc/HOSTNAME file (as root):

ilcbuild@example:~> su -
Password:
example:~ # vi /etc/HOSTNAME
					

Delete old name and set new value, for example test317.java.boot.by. Save and close the file.

example:~ # cat /etc/HOSTNAME
test317.java.boot.by
example:~ #
					

Type the following commands:

example:~ # hostname test317.java.boot.by
example:~ # hostname
test317.java.boot.by
example:~ #
					

Now, you need to edit /etc/hosts file.

example:~ # vi /etc/hosts
					

Change all old hostnames with newer one.

example:~ # cat /etc/hosts
#
# 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
#

127.0.0.1       localhost

# special IPv6 addresses
::1             localhost ipv6-localhost ipv6-loopback

fe00::0         ipv6-localnet

ff00::0         ipv6-mcastprefix
ff02::1         ipv6-allnodes
ff02::2         ipv6-allrouters
ff02::3         ipv6-allhosts

192.168.87.128 test317.java.boot.by test317

					

Re-login with SSH - shell prompt will have the new hostname now:
