4 Get root Privileges
After the reboot you can login with your previously created username (e.g. administrator). Because we must run all the steps from this tutorial with root privileges, we can either prepend all commands in this tutorial with the string sudo, or we become root right now by typing
(You can as well enable the root login by running
sudo passwd root
and giving root a password. You can then directly log in as root, but this is frowned upon by the Ubuntu developers and community for various reasons. See http://ubuntuforums.org/showthread.php?t=765414.)
5 Install The SSH Server (Optional)
If you did not install the OpenSSH server during the system installation, you can do it now:
aptitude install ssh openssh-server
From now on you can use an SSH client such as PuTTY and connect from your workstation to your Ubuntu 10.04 server and follow the remaining steps from this tutorial.
6 Install vim-nox (Optional)
I'll use vi as my text editor in this tutorial. The default vi program has some strange behaviour on Ubuntu and Debian; to fix this, we install vim-nox:
aptitude install vim-nox
(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):
# 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
Then restart your network:
Then edit /etc/hosts. Make it look like this:
127.0.0.1 localhost.localdomain localhost 192.168.0.100 server1.example.com server1 # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters
echo server1.example.com > /etc/hostname
Both should show server1.example.com 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:
# deb cdrom:[Ubuntu-Server 10.04 LTS _Lucid Lynx_ - Release amd64 (20100427)]/ lucid main restricted #deb cdrom:[Ubuntu-Server 10.04 LTS _Lucid Lynx_ - Release amd64 (20100427)]/ lucid main restricted # See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to # newer versions of the distribution. deb http://de.archive.ubuntu.com/ubuntu/ lucid main restricted deb-src http://de.archive.ubuntu.com/ubuntu/ lucid main restricted ## Major bug fix updates produced after the final release of the ## distribution. deb http://de.archive.ubuntu.com/ubuntu/ lucid-updates main restricted deb-src http://de.archive.ubuntu.com/ubuntu/ lucid-updates main restricted ## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu ## team.

to update the apt package database and
to install the latest updates (if there are any). If you see that a new kernel gets installed as part of the updates, you should reboot the system afterwards:
9 Change The Default Shell
/bin/sh is a symlink to /bin/dash, however we need /bin/bash, not /bin/dash. Therefore we do this:
Install dash as /bin/sh? <-- No
If you don't do this, the ISPConfig installation will fail.
10 Disable AppArmor
AppArmor is a security extension (similar to SELinux) that should provide extended security. In my opinion you don't need it to configure a secure system, and it usually causes more problems than advantages (think of it after you have done a week of trouble-shooting because some service wasn't working as expected, and then you find out that everything was ok, only AppArmor was causing the problem). Therefore I disable it (this is a must if you want to install ISPConfig later on).
We can disable it like this:
update-rc.d -f apparmor remove
aptitude remove apparmor apparmor-utils
11 Synchronize the System Clock
It is a good idea to synchronize the system clock with an NTP (network time protocol) server over the Internet. Simply run
aptitude install ntp ntpdate
and your system time will always be in sync.
