The Perfect Server – Ubuntu 10.10 [ISPConfig 3]


This tutorial shows how to prepare an Ubuntu 10.10 (Maverick Meerkat) server for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more.

Please note that this setup does not work for ISPConfig 2! It is valid for ISPConfig 3 only!

I do not issue any guarantee that this tutorial will work for you!

 

1 Requirements

To install such a system you will need the following:

  • the Ubuntu 10.10 server CD, available here: http://releases.ubuntu.com/releases/10.10/ubuntu-10.10-server-i386.iso (i386) or http://releases.ubuntu.com/releases/10.10/ubuntu-10.10-server-amd64.iso (x86_64)
  • a fast Internet connection.

 

2 Preliminary Note

In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100 and the gateway 192.168.0.1. These settings might differ for you, so you have to replace them where appropriate.

 

3 The Base System

Insert your Ubuntu install CD into your system and boot from it. Select your language:

1

 

Then select Install Ubuntu Server:

2

Choose your language again (?):

3

Then select your location:

4

5

6

Choose a keyboard layout (you will be asked to press a few keys, and the installer will try to detect your keyboard layout based on the keys you pressed):

7

8

The installer checks the installation CD, your hardware, and configures the network with DHCP if there is a DHCP server in the network:

9

10

Enter the hostname. In this example, my system is called server1.example.com, so I enter server1:

11

Please check if the installer detected your time zone correctly. If so, select Yes, otherwise No:

12

Now you have to partition your hard disk. For simplicity’s sake I select Guided – use entire disk and set up LVM – this will create one volume group with two logical volumes, one for the / file system and another one for swap (of course, the partitioning is totally up to you – if you know what you’re doing, you can also set up your partitions manually).

13

Select the disk that you want to partition:

14

When you’re asked Write the changes to disks and configure LVM?, select Yes:

15

If you have selected Guided – use entire disk and set up LVM, the partitioner will create one big volume group that uses all the disk space. You can now specify how much of that disk space should be used by the logical volumes for / and swap. It makes sense to leave some space unused so that you can later on expand your existing logical volumes or create new ones – this gives you more flexibility.

16

When you’re finished, hit Yes when you’re asked Write the changes to disks?:

17

Afterwards, your new partitions are being created and formatted:

18

Now the base system is being installed:

19

Create a user, for example the user Administrator with the user name administrator (don’t use the user name admin as it is a reserved name on Ubuntu 10.10):

20

21

22

23

I don’t need an encrypted private directory, so I choose No here:

24

Next the package manager apt gets configured. Leave the HTTP proxy line empty unless you’re using a proxy server to connect to the Internet:

26

27

I’m a little bit old-fashioned and like to update my servers manually to have more control, therefore I select No automatic updates. Of course, it’s up to you what you select here:

29

We need a DNS, mail, and LAMP server, but nevertheless I don’t select any of them now because I like to have full control over what gets installed on my system. We will install the needed packages manually later on. The only item I select here is OpenSSH server so that I can immediately connect to the system with an SSH client such as PuTTY after the installation has finished:

30

The installation continues:

31

The GRUB boot loader gets installed:

32

Select Yes when you are asked Install the GRUB boot loader to the master boot record?:

33

The base system installation is now finished. Remove the installation CD from the CD drive and hit Continue to reboot the system:

34

On to the next step…

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-src http://security.ubuntu.com/ubuntu maverick-security universe
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.

12 Install Postfix, Courier, Saslauthd, MySQL, rkhunter, binutils

We can install Postfix, Courier, Saslauthd, MySQL, rkhunter, and binutils with a single command:

aptitude install postfix postfix-mysql postfix-doc mysql-client mysql-server courier-authdaemon courier-authlib-mysql courier-pop courier-pop-ssl courier-imap courier-imap-ssl libsasl2-2 libsasl2-modules libsasl2-modules-sql sasl2-bin libpam-mysql openssl getmail4 rkhunter binutils maildrop

You will be asked the following questions:

New password for the MySQL “root” user: <– yourrootsqlpassword
Repeat password for the MySQL “root” user: <– yourrootsqlpassword
Create directories for web-based administration? <– No
General type of mail configuration: <– Internet Site
System mail name: <– server1.example.com
SSL certificate required <– Ok

We want MySQL to listen on all interfaces, not just localhost, therefore we edit /etc/mysql/my.cnf and comment out the line bind-address = 127.0.0.1:

vi /etc/mysql/my.cnf

[...]
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address           = 127.0.0.1
[...]

Then we restart MySQL:

/etc/init.d/mysql restart

Now check that networking is enabled. Run

netstat -tap | grep mysql

The output should look like this:

root@server1:~# netstat -tap | grep mysql
tcp        0      0 *:mysql                 *:*                     LISTEN      9815/mysqld
root@server1:~#

During the installation, the SSL certificates for IMAP-SSL and POP3-SSL are created with the hostname localhost. To change this to the correct hostname (server1.example.com in this tutorial), delete the certificates…

cd /etc/courier
rm -f /etc/courier/imapd.pem
rm -f /etc/courier/pop3d.pem

… and modify the following two files; replace CN=localhost with CN=server1.example.com (you can also modify the other values, if necessary):

vi /etc/courier/imapd.cnf

[...]
CN=server1.example.com
[...]

vi /etc/courier/pop3d.cnf

[...]
CN=server1.example.com
[...]

Then recreate the certificates…

mkimapdcert
mkpop3dcert

… and restart Courier-IMAP-SSL and Courier-POP3-SSL:

/etc/init.d/courier-imap-ssl restart
/etc/init.d/courier-pop-ssl restart

 

13 Install Amavisd-new, SpamAssassin, And Clamav

To install amavisd-new, SpamAssassin, and ClamAV, we run

aptitude install amavisd-new spamassassin clamav clamav-daemon zoo unzip bzip2 arj nomarch lzop cabextract apt-listchanges libnet-ldap-perl libauthen-sasl-perl clamav-docs daemon libio-string-perl libio-socket-ssl-perl libnet-ident-perl zip libnet-dns-perl

 

14 Install Apache2, PHP5, phpMyAdmin, FCGI, suExec, Pear, And mcrypt

Apache2, PHP5, phpMyAdmin, FCGI, suExec, Pear, and mcrypt can be installed as follows:

aptitude install apache2 apache2.2-common apache2-doc apache2-mpm-prefork apache2-utils libexpat1 ssl-cert libapache2-mod-php5 php5 php5-common php5-gd php5-mysql php5-imap phpmyadmin php5-cli php5-cgi libapache2-mod-fcgid apache2-suexec php-pear php-auth php5-mcrypt mcrypt php5-imagick imagemagick libapache2-mod-suphp libopenssl-ruby libapache2-mod-ruby

You will see the following question:

Web server to reconfigure automatically: <– apache2
Configure database for phpmyadmin with dbconfig-common? <– No

Then run the following command to enable the Apache modules suexec, rewrite, ssl, actions, and include (plus dav, dav_fs, and auth_digest if you want to use WebDAV):

a2enmod suexec rewrite ssl actions include

a2enmod dav_fs dav auth_digest

Restart Apache afterwards:

/etc/init.d/apache2 restart

 

15 Install PureFTPd And Quota

PureFTPd and quota can be installed with the following command:

aptitude install pure-ftpd-common pure-ftpd-mysql quota quotatool

Edit the file /etc/default/pure-ftpd-common

vi /etc/default/pure-ftpd-common

… and make sure that the start mode is set to standalone and set VIRTUALCHROOT=true:

[...]
STANDALONE_OR_INETD=standalone
[...]
VIRTUALCHROOT=true
[...]

Now we configure PureFTPd to allow FTP and TLS sessions. FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure.

If you want to allow FTP and TLS sessions, run

echo 1 > /etc/pure-ftpd/conf/TLS

In order to use TLS, we must create an SSL certificate. I create it in /etc/ssl/private/, therefore I create that directory first:

mkdir -p /etc/ssl/private/

Afterwards, we can generate the SSL certificate as follows:

openssl req -x509 -nodes -days 7300 -newkey rsa:2048 -keyout /etc/ssl/private/pure-ftpd.pem -out /etc/ssl/private/pure-ftpd.pem

Country Name (2 letter code) [AU]: <– Enter your Country Name (e.g., “DE”).
State or Province Name (full name) [Some-State]:
<– Enter your State or Province Name.
Locality Name (eg, city) []:
<– Enter your City.
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
<– Enter your Organization Name (e.g., the name of your company).
Organizational Unit Name (eg, section) []:
<– Enter your Organizational Unit Name (e.g. “IT Department”).
Common Name (eg, YOUR name) []:
<– Enter the Fully Qualified Domain Name of the system (e.g. “server1.example.com”).
Email Address []:
<– Enter your Email Address.

Change the permissions of the SSL certificate:

chmod 600 /etc/ssl/private/pure-ftpd.pem

Then restart PureFTPd:

/etc/init.d/pure-ftpd-mysql restart

Edit /etc/fstab. Mine looks like this (I added ,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 to the partition with the mount point /):

vi /etc/fstab

# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    nodev,noexec,nosuid 0       0
/dev/mapper/server1-root /               ext4    errors=remount-ro,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 0       1
# /boot was on /dev/sda1 during installation
UUID=a8f37dcf-5836-485c-a451-3ae2f0f47720 /boot           ext2    defaults        0       2
/dev/mapper/server1-swap_1 none            swap    sw              0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0

To enable quota, run these commands:

mount -o remount /

quotacheck -avugm
quotaon -avug

 

16 Install BIND DNS Server

BIND can be installed as follows:

aptitude install bind9 dnsutils

 

17 Install Vlogger, Webalizer, And AWstats

Vlogger, webalizer, and AWstats can be installed as follows:

aptitude install vlogger webalizer awstats geoip-database

 

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-2.13.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*

 

19 Install fail2ban

This is optional but recommended, because the ISPConfig monitor tries to show the fail2ban log:

aptitude install fail2ban

20 Install SquirrelMail

To install the SquirrelMail webmail client, run

aptitude install squirrelmail

Then create the following symlink…

ln -s /usr/share/squirrelmail/ /var/www/webmail

… and configure SquirrelMail:

squirrelmail-configure

We must tell SquirrelMail that we are using Courier-IMAP/-POP3:

21 Install ISPConfig 3

To install ISPConfig 3 from the latest released version, do this:

cd /tmp
wget http://www.ispconfig.org/downloads/ISPConfig-3-stable.tar.gz
tar xfz ISPConfig-3-stable.tar.gz
cd ispconfig3_install/install/

he next step is to run

php -q install.php

This will start the ISPConfig 3 installer. The installer will configure all services like Postfix, SASL, Courier, etc. for you. A manual setup as required for ISPConfig 2 (perfect setup guides) is not necessary.

root@server1:/tmp/ispconfig3_install/install# php -q install.php

The installer automatically configures all underlying services, so no manual configuration is needed.

Afterwards you can access ISPConfig 3 under http://server1.example.com:8080/ or http://192.168.0.100:8080/. Log in with the username admin and the password admin (you should change the default password after your first login):

The system is now ready to be used.

22 Additional Notes

22.1 OpenVZ

If the Ubuntu server that you’ve just set up in this tutorial is an OpenVZ container (virtual machine), you should do this on the host system (I’m assuming that the ID of the OpenVZ container is 101 – replace it with the correct VPSID on your system):

VPSID=101
for CAP in CHOWN DAC_READ_SEARCH SETGID SETUID NET_BIND_SERVICE NET_ADMIN SYS_CHROOT SYS_NICE CHOWN DAC_READ_SEARCH SETGID SETUID NET_BIND_SERVICE NET_ADMIN SYS_CHROOT SYS_NICE
do
vzctl set $VPSID –capability ${CAP}:on –save
done

 

22.2 SquirrelMail

Lots of people have reported problems (such as getting 404 Not Found errors) using the SquirrelMail webmail package in their web sites created through ISPConfig 3. This guide explains how to configure SquirrelMail on an Ubuntu 10.10 server so that you can use it from within your web sites (created through ISPConfig).

SquirrelMail’s Apache configuration is in the file /etc/squirrelmail/apache.conf, but this file isn’t loaded by Apache because it is not in the /etc/apache2/conf.d/ directory. Therefore we create a symlink called squirrelmail.conf in the /etc/apache2/conf.d/ directory that points to /etc/squirrelmail/apache.conf and reload Apache afterwards:

cd /etc/apache2/conf.d/
ln -s ../../squirrelmail/apache.conf squirrelmail.conf
/etc/init.d/apache2 reload

That’s it already – /etc/apache2/conf.d/squirrelmail.conf defines an alias called /squirrelmail that points to SquirrelMail’s installation directory /usr/share/squirrelmail.

Now go to the PHP open_basedir field on the Options tab of your web site in ISPConfig and add the directories /usr/share/squirrelmail and /etc/squirrelmail (that’s the directory where SquirrelMail’s configuration is stored) to the line, e.g. as follows:

50

Wait two or three minutes until ISPConfig has updated the site configuration. You can now access SquirrelMail from your web site as follows:

http://www.example.com/squirrelmail

You can also access it from the ISPConfig control panel vhost as follows (this doesn’t need any configuration in ISPConfig):

http://server1.example.com:8080/squirrelmail

If you’d like to use the alias /webmail instead of /squirrelmail, simply open /etc/apache2/conf.d/squirrelmail.conf

vi /etc/apache2/conf.d/squirrelmail.conf

… and add the line Alias /webmail /usr/share/squirrelmail:

Alias /squirrelmail /usr/share/squirrelmail
Alias /webmail /usr/share/squirrelmail

<Directory /usr/share/squirrelmail>
  Options FollowSymLinks
  <IfModule mod_php5.c>
    php_flag register_globals off
  </IfModule>
  <IfModule mod_dir.c>
    DirectoryIndex index.php
  </IfModule>

  # access to configtest is limited by default to prevent information leak
  <Files configtest.php>
    order deny,allow
    deny from all
    allow from 127.0.0.1
  </Files>
</Directory>

# users will prefer a simple URL like http://webmail.example.com
#<VirtualHost 1.2.3.4>
#  DocumentRoot /usr/share/squirrelmail
#  ServerName webmail.example.com
#</VirtualHost>

# redirect to https when available (thanks omen@descolada.dartmouth.edu)
#
#  Note: There are multiple ways to do this, and which one is suitable for
#  your site's configuration depends. Consult the apache documentation if
#  you're unsure, as this example might not work everywhere.
#
#<IfModule mod_rewrite.c>
#  <IfModule mod_ssl.c>
#    <Location /squirrelmail>
#      RewriteEngine on
#      RewriteCond %{HTTPS} !^on$ [NC]
#      RewriteRule . https://%{HTTP_HOST}%{REQUEST_URI}  [L]
#    </Location>
#  </IfModule>
#</IfModule>

Then reload Apache:

/etc/init.d/apache2 reload

Now you can access Squirrelmail as follows:

http://www.example.com/webmail
http://server1.example.com:8080/webmail

If you’d like to define a vhost like webmail.example.com where your users can access SquirrelMail, you’d have to add the following vhost configuration to /etc/apache2/conf.d/squirrelmail.conf:

vi /etc/apache2/conf.d/squirrelmail.conf

[...]
<VirtualHost 1.2.3.4:80>
  DocumentRoot /usr/share/squirrelmail
  ServerName webmail.example.com
</VirtualHost>

Make sure you replace 1.2.3.4 with the correct IP address of your server. Of course, there must be a DNS record for webmail.example.com that points to the IP address that you use in the vhost configuration. Also make sure that the vhost webmail.example.com does not exist in ISPConfig (otherwise both vhosts will interfere with each other!).

Now reload Apache…

/etc/init.d/apache2 reload

… and you can access SquirrelMail under http://webmail.example.com!
