By default, the Ubuntu installer has configured our system to get
its IP address and other network settings via DHCP. This is not what we
want so we have to change the server to have a static IP address. Edit /etc/network/interfaces and adjust it per your requirements. For this example we are using an IP address of 192.168.167.210 for this server.
Now,
there are a myriad of examples on the web and I am including a few
links to them for convenience sake in case they explain this better.
(they probably do) ;o)
vi /etc/network/interfaces
|
# This file describes the network interfaces available on your system auto lo # The primary network interface auto eth0 |
Now, restart your network:
/etc/init.d/networking restart
Then edit /etc/hosts.
We are telling the server what names it is going to answer to and to
which IP addresses those names belong. This is somewhat analogous to
the Windows hosts file if you are familiar with Windows:
vi /etc/hosts
|
127.0.0.1 localhost.localdomain localhost 192.168.0.100 server1.example.com server1 # The following lines are desirable for IPv6 capable hosts |
Now execute the following commands.
hostname
hostname -f
The results from both commands should show server1.example.com. If they do not, reboot the system:
shutdown -r now
Log back into your server and try the hostname commands again.
hostname
hostname -f
They should show server1.example.com.
