4 Enable The root Account

After the reboot you can login with your previously created username (e.g. administrator). Because we have to run all the steps from this tutorial as root user, so we will enable the root account.

Run

sudo passwd root

and give root a password. Afterwards we can switch root by running

su

 

5 Install The SSH Server (Optional)

If you did not install the OpenSSH server during the system installation, you can do it now:

apt-get install ssh openssh-server

From now on you can use an SSH client such as PuTTY and connect from your workstation to your Ubuntu 8.04 LTS server and follow the remaining steps from this tutorial.

 

6 Install vim-full (Optional)

I'll use vi as my text editor in this tutorial. The default vi program has some strange behavior on Ubuntu; to fix this, we install vim-full:

apt-get install vim-full

(You don't have to do this if you use a different text editor such as joe or nano.)

 

7 Configure The Network

Because the Ubuntu installer has configured our system to get its network settings via DHCP, we have to change that now because a server should have a static IP address. Edit /etc/network/interfaces and adjust it to your needs (in this example setup I will use the IP address 192.168.0.100):

vi /etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.0.100
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1

Please make sure your network configuration are set correctly, feel free to change that based on your network configuration.

Then restart your network:

/etc/init.d/networking restart

Then edit /etc/hosts. Make it look like this:

vi /etc/hosts

127.0.0.1     localhost.localdomain localhost
192.168.0.100 server1.tm.local server1

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Now run

echo server1.tm.local > /etc/hostname
/etc/init.d/hostname.sh start

Afterwards, run

hostname
hostname -f

Both should show server1.tm.local now.

 

8 Edit /etc/apt/sources.list And Update Your Linux Installation

Edit /etc/apt/sources.list. Comment out or remove the installation CD from the file and make sure that the universe and multiverse repositories are enabled. It should look like this:

vi /etc/apt/sources.list

#
# deb cdrom:[Ubuntu-Server 8.04 _Hardy Heron_ - Release i386 (20080423.2)]/ hardy main restricted

Then run

apt-get update

to update the apt package database and

apt-get upgrade

to install the latest updates (if there are any).

 

9 Disable AppArmor (This is a must for things to go well here)

AppArmor is a security extension (similar to SELinux) that should provide extended security, which usually causes more problems than advantages. Therefore I disable it.

We can disable it like this:

/etc/init.d/apparmor stop
update-rc.d -f apparmor remove
