The Perfect Server - Debian Squeeze (Debian 6.0) With BIND, Dovecot & Nginx [ISPConfig 3] - Page 3
4 Install The SSH Server
If you didn't install an SSH server during the basic system installation, you can do it now:
apt-get install ssh openssh-server
Note: The commands in this tutorial assume that you are logged in as root. You might also want to delete the CD-ROM line in your /etc/apt/sources.list:
and press d twice in quick succession to delete a single line until all the CD-ROM entries are deleted. If you delete a line too many enter :q! to quit without saving and try again.
You should be able to use a terminal or SSH client such as PuTTY and connect from your workstation to your Debian Squeeze server and follow the remaining steps from this tutorial.
5 Install vim-nox (Recommended)
If you use vi as the in-terminal text editor you should install the following package. The default vi program on Debian and Ubuntu has some serious bugs that make editing impossible at times, so to fix this we install vim-nox:
apt-get install vim-nox
(You may skip that step and install a different text editor such as joe or nano instead if you prefer it to vi.)
6 Configure The Network
Because the Debian Squeeze installer has configured our system to get its network settings via DHCP, you have to change that configuration now because a server should have a static IP address. Edit /etc/network/interfaces with a text editor and adjust it to suit your needs (in this example setup the IP address 192.168.0.100 is used). Please note that allow-hotplug eth0 should be replaced with auto eth0 otherwise restarting the network interfaces does not work, and would require a system reboot. To edit with vi enter:
# 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 #allow-hotplug eth0 #iface eth0 inet dhcp 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 edit /etc/hosts. It should look similar to 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 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
and edit the hostname that way.
After both commands server1.example.com must appear! If you already set the hostname and domain name during the installation process it should probably be correct although the IP address and the fully qualified domain name (FQDN) must be inserted in the /etc/hosts file. In a local installation you could use the .local as the top-level domain (TLD) but in this scenario you need a DNS server that is configured properly to resolve local IP addresses.
7 Add the Dotdeb Repository And Update Your Debian System
This step is critical for getting nginx to work with ISPConfig 3 and your Debian 6 system. Add the Dotdeb repository by editing the /etc/apt/sources.list file and inserting the 2 lines and optional comment and download and add the GPG key:
[...] # Dotdeb repository deb http://packages.dotdeb.org squeeze all deb-src http://packages.dotdeb.org squeeze all [...]
Then fetch the appropriate GnuPG key:
cat dotdeb.gpg | apt-key add -
Also make sure that your /etc/apt/sources.list contains the squeeze-updates repository (this makes sure you always get the newest updates for the ClamAV virus scanner - this project publishes releases very often, and sometimes old versions stop working).
[...] deb http://ftp.de.debian.org/debian/ squeeze-updates main [...]
to update the apt package repository database and if any upgrades are available they will be available to install when you:
8 Change The Default Shell
/bin/sh is a symlink to /bin/dash, however /bin/bash is necessary not /bin/dash. Therefore do this:
Use dash as the default system shell (/bin/sh)? <-- No
9 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:
apt-get install ntp ntpdate
to keep your system time in sync.
