The Perfect Server - Ubuntu 10.10 [ISPConfig 3] - Page 3

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

sudo su

(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 10.10 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):

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

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.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

Now run

echo server1.example.com > /etc/hostname
/etc/init.d/hostname restart

Afterwards, run

hostname
hostname -f

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:

vi /etc/apt/sources.list

#
# deb cdrom:[Ubuntu-Server 10.10 _Maverick Meerkat_ - Release i386 (20101007)]/ maverick main restricted

#deb cdrom:[Ubuntu-Server 10.10 _Maverick Meerkat_ - Release i386 (20101007)]/ maverick main restricted

deb http://security.ubuntu.com/ubuntu maverick-security multiverse
deb-src http://security.ubuntu.com/ubuntu maverick-security multiverse

Then run

aptitude update

to update the apt package database and

aptitude safe-upgrade

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:

reboot

 

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:

dpkg-reconfigure dash

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:

/etc/init.d/apparmor stop
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.

Hi, and thanks for the well-detailed tutorial.

Just one (trivial?) question: is aptitude installed in an Ubuntu 10.10 server default install [I found that there was no aptitude on a 10.10-rc desktop default install]. If so, before the first aptitude command you should enter an

apt-get install aptitude

Thanks again, and keep up the good work!

apt(APTitude)-get you can´t install a package with itself.

From: vinyll at: 2011-05-30 22:26:12

yes, you can install aptitude.

From: Kevin at: 2010-10-22 14:50:34

When you are installing the sever from disc you can manual config the IP address and gateway plus add the nameservers.

If you are not sure how to do that just wait till it find the dhcp setting the yuse the tab button to go back.

Or just unplug the network cable and you will get the option screen come up

From: George at: 2010-10-27 07:47:25

Yeah! I have the exact same problem, and i cant figure it out??

From: Alex at: 2010-11-01 07:49:47

Hi, I had same problem at first so had a look around and realised that the gateway and network didn't match. I had to change mine to 192.168.80.1 and 192.168.80.0 respectively. Hope this helps

From: Carlos R. Moreira at: 2011-04-04 22:51:52

I had the same problem here...

What i did was returning the network config to dhcp, run aptitude update and made a safe-upgrade, reboot, uninstalled apparmor then reconfigured the network to static...

All working now, hope it helps...

Hi, I'm a noob.  I've been following this tutorial to get a ubuntu server up and running.  I got my eth0 setup for a static IP fine but I had problems with the - sudo aptitude update.  Since I was able to ssh into the server I knew the interface worked.  I was receiving a 'Temporary failure resolving 'us.archive.ubuntu.com'' error.

Just wanted to make a note that you should check your - resolv.conf to be sure your DNS nameserver is setup right.  The command is - sudo vi /etc/resolv.conf.  I set this to my gateway IP.  You can google to find more info as I know you can add several nameservers.

The only reason I started getting this error is because I had to switch networks.  Hope this helps someone.  Thanks, Luke.

18 Install Jailkit

Jailkit is needed only if you want to chroot SSH users. It can be installed as follows (important: Jailkit must be installed before ISPConfig - it cannot be installed afterwards!):

aptitude install build-essential autoconf automake1.9 libtool flex bison debhelper

cd /tmp
wget http://olivier.sessink.nl/jailkit/jailkit-2.12.tar.gz
tar xvfz jailkit-2.12.tar.gz
cd jailkit-2.12
./debian/rules binary
cd ..
dpkg -i jailkit_2.12-1_*.deb
rm -rf jailkit-2.12*

Can someone tell me what  './debian/rules binary' is suppose to do here? I type it in and it says, its not a directory.  I'm stuck here. :(

From: Anonymous at: 2011-02-28 01:23:56

same problem here. bash returns "No such file or directory"

From: Adam at: 2010-10-29 07:55:24

From: Gerry at: 2011-04-04 11:15:59

echo1 > /etc/pure-ftd/conf/TLS

the respose is then:

echo1: command not found...

 

Anyone...?

Jailkit has released anew version 2.13 and with slightly changes to step 18 you can install latest version of Jailkit.

cd /tmp
wget http://olivier.sessink.nl/jailkit/jailkit-2.13.tar.gz
tar xvfz jailkit-2.13.tar.gz
cd jailkit-2.13
./debian/rules binary
cd ..
dpkg -i ../jailkit_2.13-1_*.deb
rm -rf jailkit-2.13*

 Just a little update and I hope this is of any help for whom want to follow this great tutorial!

Cheers All

From: at: 2011-01-03 05:04:45

Just a quick note:

dpkg -i ../jailkit_2.13-1_*.deb

 should be

dpkg -i jailkit_2.13-1_*.deb

Hello,

Could someone tell me wich packages I don't install if I don't want an email server?

 Would it cause problems to ISPconfig?

 

 Thanks!

After following this guide I can not log into ISPCONFIG3.

I tried reinstalling, changing the password directly via phpmyadmin, but nothing seems to work.

FYI: The installation didn't give me any errors.

I get the following message.

I used the above instructions as detailed in 22.2 Squirrelmail above. When I attempt to access http://mydomain.net/squirrelmail the browser attempts to download a file called 'squirrelmail' to my local hd. The file is a copy of the /usr/share/squirrelmail/index.php file.

Any suggestions on how to correct this?

Hello there!
I always post about problems but today I am happy to say that this manual worked perfect for me!
at once!

I am testing it in my server at home Ubuntu 10.10 ( btw I don't have a static IP and the installation worked perfect)

I am system administrator and at work I use CentOs and Ubuntu Server in few different servers.

I have to say that this is exactly what I was looking for.
Thank you!
