This tutorial shows how to set up an Ubuntu Hardy Heron (Ubuntu 8.04 LTS) based server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Courier POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of Ubuntu 8.04 LTS, but should apply to the 64-bit version with very little modifications as well.

I will use the following software:
* Web Server: Apache 2.2 with PHP 5.2.4 and Ruby

  • Database Server: MySQL 5.0
  • Mail Server: Postfix
  • DNS Server: BIND9
  • FTP Server: proftpd
  • POP3/IMAP: I will use Maildir format and therefore install Courier-POP3/Courier-IMAP.
  • Webalizer for web site statistics


In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig (i.e., ISPConfig runs on it out of the box).

I want to say first that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!


1 Requirements


To install such a system you will need the following:
* the Ubuntu 8.04 LTS server CD, available here: ftp://releases.ubuntu.com/releases/hardy/ubuntu-8.04-server-i386.iso

  • 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:



Then select Install Ubuntu Server :



Choose your language again (?):



Then select your location:





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):







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







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



Now you have to partition your hard disk. For simplicity's sake I will create one big partition (with the mount point / ) and a little swap partition so I select Guided -use entire disk (of course, the partitioning is totally up to you - if you like, you can create more than just one big partition, and you can also use LVM):



Select the disk that you want to partition:



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



Afterwards, your new partitions are being created and formatted.

Now the base system is being installed:





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 8.04):









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:





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:



The installation continues:



The GRUB boot loader gets installed:



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



On to the next step…

4 Enable The root Account


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

Run

sudo passwd root


and give root a password. Afterwards we become 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 and Debian; 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


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  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.example.com > /etc/hostname
/etc/init.d/hostname.sh start


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-src http://security.ubuntu.com/ubuntu hardy-security multiverse


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 Change The Default Shell


/bin/sh is a symlink to /bin/dash , however we need /bin/bash , not /bin/dash . Therefore we do this:

ln -sf /bin/bash /bin/sh


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


Till told me that he also had to do this step (which was not necessary on my installation), so if you want to go sure, do this on your system as well:

apt-get remove apparmor apparmor-utils


11 Install Some Software


Now we install a few packages that are needed later on. Run

apt-get install binutils cpp fetchmail flex gcc libarchive-zip-perl libc6-dev libcompress-zlib-perl libdb4.3-dev libpcre3 libpopt-dev lynx m4 make ncftp nmap openssl perl perl-modules unzip zip zlib1g-dev autoconf automake1.9 libtool bison autotools-dev g++ build-essential


(This command must go into one line !)


12 Quota


(If you have chosen a different partitioning scheme than I did, you must adjust this chapter so that quota applies to the partitions where you need it.)

To install quota, run

apt-get install quota


Edit /etc/fstab . Mine looks like this (I added ,usrquota,grpquota to the partition with the mount point / ):

vi /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point>  <type>  <options>  <dump>  <pass>
proc  /proc  proc  defaults  00
# /dev/sda1
UUID=6af53069-0d51-49be-b275-aeaea8d780c5 /ext3  relatime,errors=remount-ro,usrquota,grpquota 01
# /dev/sda5
UUID=d8e1f66c-1442-423e-b442-8ae66eded9d7 none  swap  sw  00
/dev/scd0  /media/cdrom0  udf,iso9660 user,noauto,exec,utf8 00
/dev/fd0  /media/floppy0  auto  rw,user,noauto,exec,utf8 00


To enable quota, run these commands:

touch /quota.user /quota.group
chmod 600 /quota.*
mount -o remount /
quotacheck -avugm
quotaon -avug



13 DNS Server


Run

apt-get install bind9


For security reasons we want to run BIND chrooted so we have to do the following steps:

/etc/init.d/bind9 stop


Edit the file /etc/default/bind9 so that the daemon will run as the unprivileged user bind , chrooted to /var/lib/named . Modify the line: OPTIONS=“-u bind” so that it reads OPTIONS=“-u bind -t /var/lib/named” :

vi /etc/default/bind9
OPTIONS="-u bind -t /var/lib/named"
# Set RESOLVCONF=no to not run resolvconf
RESOLVCONF=yes


Create the necessary directories under /var/lib :

mkdir -p /var/lib/named/etc
mkdir /var/lib/named/dev
mkdir -p /var/lib/named/var/cache/bind
mkdir -p /var/lib/named/var/run/bind/run


Then move the config directory from /etc to /var/lib/named/etc :

mv /etc/bind /var/lib/named/etc


Create a symlink to the new config directory from the old location (to avoid problems when bind gets updated in the future):

ln -s /var/lib/named/etc/bind /etc/bind


Make null and random devices, and fix permissions of the directories:

mknod /var/lib/named/dev/null c1 3
mknod /var/lib/named/dev/random c1 8
chmod 666 /var/lib/named/dev/null /var/lib/named/dev/random
chown -R bind:bind /var/lib/named/var/*
chown -R bind:bind /var/lib/named/etc/bind


We need to modify /etc/default/syslogd so that we can still get important messages logged to the system logs. Modify the line: SYSLOGD=“” so that it reads: SYSLOGD=“-a /var/lib/named/dev/log” :

vi /etc/default/syslogd
#
# Top configuration file for syslogd
#

#
# Full documentation of possible arguments are found in the manpage
# syslogd(8).
#

#
# For remote UDP logging use SYSLOGD="-r"
#
SYSLOGD="-a /var/lib/named/dev/log"


Restart the logging daemon:

/etc/init.d/sysklogd restart


Start up BIND, and check /var/log/syslog for errors:

/etc/init.d/bind9 start



14 MySQL


In order to install MySQL, we run

apt-get install mysql-server mysql-client libmysqlclient15-dev


You will be asked to provide a password for the MySQL root user -this password is valid for the user root@localhost as well as root@server1.example.com , so we don't have to specify aMySQL root password manually later on (as was the case with previous Ubuntu versions):

New password for the MySQL “root” user: ←- yourrootsqlpassword
Repeat password for the MySQL “root” user: ←- yourrootsqlpassword

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      5869/mysqld
 root@server1:~#

15 Postfix With SMTP-AUTH And TLS


In order to install Postfix with SMTP-AUTH and TLS do the following steps:

apt-get install postfix libsasl2-2 sasl2-bin libsasl2-modules procmail


You will be asked two questions. Answer as follows:

General type of mail configuration: ←- Internet Site
System mail name: ←- server1.example.com

Then run

dpkg-reconfigure postfix


Again, you'll be asked some questions:

General type of mail configuration: ←- Internet Site
System mail name: ←- server1.example.com
Root and postmaster mail recipient: ←- [blank]
Other destinations to accept mail for (blank for none): ←- server1.example.com, localhost.example.com, localhost.localdomain, localhost
Force synchronous updates on mail queue? ←- No
Local networks: ←- 127.0.0.0/8
Use procmail for local delivery? ←- Yes
Mailbox size limit (bytes): ←- 0
Local address extension character: ←- +
Internet protocols to use: ←- all

Next, do this:

postconf -e 'smtpd_sasl_local_domain ='
postconf -e 'smtpd_sasl_auth_enable =yes'
postconf -e 'smtpd_sasl_security_options =noanonymous'
postconf -e 'broken_sasl_auth_clients =yes'
postconf -e 'smtpd_sasl_authenticated_header =yes'
postconf -e 'smtpd_recipient_restrictions =permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination'
postconf -e 'inet_interfaces =all'
echo 'pwcheck_method: saslauthd' >> /etc/postfix/sasl/smtpd.conf
echo 'mech_list: plain login' >> /etc/postfix/sasl/smtpd.conf


Afterwards we create the certificates for TLS:

mkdir /etc/postfix/ssl
cd /etc/postfix/ssl/
openssl genrsa -des3 -rand /etc/hosts -out smtpd.key 1024
chmod 600 smtpd.key
openssl req -new -key smtpd.key -out smtpd.csr
openssl x509 -req -days 3650 -in smtpd.csr -signkey smtpd.key -out smtpd.crt
openssl rsa -in smtpd.key -out smtpd.key.unencrypted
mv -f smtpd.key.unencrypted smtpd.key
openssl req -new -x509 -extensions v3_ca -keyout cakey.pem -out cacert.pem -days 3650


Next we configure Postfix for TLS (make sure that you use the correct hostname for myhostname ):

postconf -e 'myhostname =server1.example.com'
postconf -e 'smtpd_tls_auth_only =no'
postconf -e 'smtp_use_tls =yes'
postconf -e 'smtpd_use_tls =yes'
postconf -e 'smtp_tls_note_starttls_offer =yes'
postconf -e 'smtpd_tls_key_file =/etc/postfix/ssl/smtpd.key'
postconf -e 'smtpd_tls_cert_file =/etc/postfix/ssl/smtpd.crt'
postconf -e 'smtpd_tls_CAfile =/etc/postfix/ssl/cacert.pem'
postconf -e 'smtpd_tls_loglevel =1'
postconf -e 'smtpd_tls_received_header =yes'
postconf -e 'smtpd_tls_session_cache_timeout =3600s'
postconf -e 'tls_random_source =dev:/dev/urandom'


The file /etc/postfix/main.cf should now look like this:

cat /etc/postfix/main.cf
# See /usr/share/postfix/main.cf.dist for acommented, more complete version


# Debian specific:  Specifying afile name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin =/etc/mailname

smtpd_banner =$myhostname ESMTP $mail_name (Ubuntu)
biff =no

# appending .domain is the MUA's job.
append_dot_mydomain =no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time =4h

readme_directory =no

# TLS parameters
smtpd_tls_cert_file =/etc/postfix/ssl/smtpd.crt
smtpd_tls_key_file =/etc/postfix/ssl/smtpd.key
smtpd_use_tls =yes
smtpd_tls_session_cache_database =btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database =btree:${data_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

myhostname =server1.example.com
alias_maps =hash:/etc/aliases
alias_database =hash:/etc/aliases
myorigin =/etc/mailname
mydestination =server1.example.com, localhost.example.com, localhost.localdomain, localhost
relayhost =mynetworks =127.0.0.0/8
mailbox_command =procmail -a "$EXTENSION"
mailbox_size_limit =0
recipient_delimiter =+
inet_interfaces =all
inet_protocols =all
smtpd_sasl_local_domain =smtpd_sasl_auth_enable =yes
smtpd_sasl_security_options =noanonymous
broken_sasl_auth_clients =yes
smtpd_sasl_authenticated_header =yes
smtpd_recipient_restrictions =permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination
smtpd_tls_auth_only =no
smtp_use_tls =yes
smtp_tls_note_starttls_offer =yes
smtpd_tls_CAfile =/etc/postfix/ssl/cacert.pem
smtpd_tls_loglevel =1
smtpd_tls_received_header =yes
smtpd_tls_session_cache_timeout =3600s
tls_random_source =dev:/dev/urandom


Authentication will be done by saslauthd . We have to change afew things to make it work properly. Because Postfix runs chrooted in /var/spool/postfix we have to do the following:

mkdir -p /var/spool/postfix/var/run/saslauthd


Now we have to edit /etc/default/saslauthd in order to activate saslauthd . Set START to yes and change the line OPTIONS=“-c -m /var/run/saslauthd” to OPTIONS=“-c -m /var/spool/postfix/var/run/saslauthd -r” :

vi /etc/default/saslauthd
#
# Settings for saslauthd daemon
# Please read /usr/share/doc/sasl2-bin/README.Debian for details.
#

# Should saslauthd run automatically on startup? (default: no)
START=yes

# Description of this saslauthd instance. Recommended.
# (suggestion: SASL Authentication Daemon)
DESC="SASL Authentication Daemon"

# Short name of this saslauthd instance. Strongly recommended.
# (suggestion: saslauthd)
NAME="saslauthd"

# Which authentication mechanisms should saslauthd use? (default: pam)
#
# Available options in this Debian package:
# getpwent  -- use the getpwent() library function
# kerberos5 -- use Kerberos 5# pam  -- use PAM
# rimap  -- use aremote IMAP server
# shadow  -- use the local shadow password file
# sasldb  -- use the local sasldb database file
# ldap  -- use LDAP (configuration is in /etc/saslauthd.conf)
#
# Only one option may be used at atime. See the saslauthd man page
# for more information.
#
# Example: MECHANISMS="pam"
MECHANISMS="pam"

# Additional options for this mechanism. (default: none)
# See the saslauthd man page for information about mech-specific options.
MECH_OPTIONS=""

# How many saslauthd processes should we run? (default: 5)
# Avalue of 0will fork anew process for each connection.
THREADS=5

# Other options (default: -c -m /var/run/saslauthd)
# Note: You MUST specify the -m option or saslauthd won't run!
#
# See /usr/share/doc/sasl2-bin/README.Debian for Debian-specific information.
# See the saslauthd man page for general information about these options.
#
# Example for postfix users: "-c -m /var/spool/postfix/var/run/saslauthd"
#OPTIONS="-c -m /var/run/saslauthd"
OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd -r"


Next add the postfix user to the sasl group (this makes sure that Postfix has the permission to access saslauthd):

adduser postfix sasl 


Now restart Postfix and start saslauthd :

/etc/init.d/postfix restart
/etc/init.d/saslauthd start


To see if SMTP-AUTH and TLS work properly now run the following command:

telnet localhost 25


After you have established the connection to your Postfix mail server type

ehlo localhost


If you see the lines

250-STARTTLS

and

250-AUTH LOGIN PLAIN

everything is fine.

The output on my system looks like this:

root@server1:/etc/postfix/ssl# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 server1.example.com ESMTP Postfix (Ubuntu)
ehlo localhost

250-8BITMIME
250 DSN
quit
221 2.0.0 Bye
Connection closed by foreign host.
root@server1:/etc/postfix/ssl#


Type

quit


to return to the system's shell.


16 Courier-IMAP/Courier-POP3


Run this to install Courier-IMAP/Courier-IMAP-SSL (for IMAPs on port 993) and Courier-POP3/Courier-POP3-SSL (for POP3s on port 995):

apt-get install courier-authdaemon courier-base courier-imap courier-imap-ssl courier-pop courier-pop-ssl courier-ssl gamin libgamin0 libglib2.0-0 


You will be asked two questions:

Create directories for web-based administration? ←- No
SSL certificate required ←- Ok

If you do not want to use ISPConfig, configure Postfix to deliver emails to auser's Maildir*:

postconf -e 'home_mailbox =Maildir/'
postconf -e 'mailbox_command ='
/etc/init.d/postfix restart


*Please note: You do not have to do this if you intend to use ISPConfig on your system as ISPConfig does the necessary configuration using procmail recipes. But please go sure to enable Maildir under Management → Server → Settings → EMail in the ISPConfig web interface.

17 Apache/PHP5/Ruby


Now we install Apache:

apt-get install apache2 apache2-doc apache2-mpm-prefork apache2-utils libexpat1 ssl-cert


Next we install PHP5 and Ruby (both as Apache modules):

apt-get install libapache2-mod-php5 libapache2-mod-ruby php5 php5-common php5-curl php5-dev php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-mhash php5-ming php5-mysql php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl


Next we edit /etc/apache2/mods-available/dir.conf :

vi /etc/apache2/mods-available/dir.conf


and change the DirectoryIndex line:

<IfModule mod_dir.c>
 
  #DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm
  DirectoryIndex index.html index.htm index.shtml index.cgi index.php index.php3 index.pl index.xhtml
 
</IfModule>


Now we have to enable some Apache modules ( SSL , rewrite , suexec , and include ):

a2enmod ssl
a2enmod rewrite
a2enmod suexec
a2enmod include


Reload the Apache configuration:

/etc/init.d/apache2 force-reload


In the next chapter (17.1) we are going to disable PHP (this is necessary only if you want to install ISPConfig on this server). Unlike PHP, Ruby is disabled by default, therefore we don't have to do it.


17.1 Disable PHP Globally


(If you do not plan to install ISPConfig on this server, please skip this section!)

In ISPConfig you will configure PHP on aper-website basis, i.e. you can specify which website can run PHP scripts and which one cannot. This can only work if PHP is disabled globally because otherwise all websites would be able to run PHP scripts, no matter what you specify in ISPConfig.

To disable PHP globally, we edit /etc/mime.types and comment out the application/x-httpd-php lines:

vi /etc/mime.types
[...]
#application/x-httpd-php  phtml pht php
#application/x-httpd-php-source  phps
#application/x-httpd-php3  php3
#application/x-httpd-php3-preprocessed  php3p
#application/x-httpd-php4  php4
[...]


Edit /etc/apache2/mods-enabled/php5.conf and comment out the following lines:

vi /etc/apache2/mods-enabled/php5.conf
<IfModule mod_php5.c>

18 Proftpd


In order to install Proftpd, run

apt-get install proftpd ucf


You will be asked aquestion:

Run proftpd: ←- standalone

For security reasons add the following lines to /etc/proftpd/proftpd.conf (thanks to Reinaldo Carvalho; more information can be found here: http://proftpd.org/localsite/Userguide/linked/userguide.html ):

vi /etc/proftpd/proftpd.conf
[...]
DefaultRoot ~IdentLookups off
ServerIdent on "FTP Server ready."
[...]


ISPConfig expects the configuration to be in /etc/proftpd.conf instead of /etc/proftpd/proftpd.conf , therefore we create asymlink (you can skip this command if you don't want to install ISPConfig):

ln -s /etc/proftpd/proftpd.conf /etc/proftpd.conf


Then restart Proftpd:

/etc/init.d/proftpd restart


19 Webalizer


To install webalizer , just run

apt-get install webalizer



20 Synchronize the System Clock


It is agood idea to synchronize the system clock with an NTP (network time protocol) server over the internet. Simply run

apt-get install ntp ntpdate


and your system time will always be in sync.


21 Install Some Perl Modules Needed By SpamAssassin (Comes With ISPConfig)

22 ISPConfig


The configuration of the server is now finished, and if you wish you can now install ISPConfig on it. Please check out the ISPConfig installation manual: http://www.ispconfig.org/manual_installation.htm


22.1 A Note On SuExec


If you want to run CGI scripts under suExec, you should specify /var/www as the home directory for websites created by ISPConfig as Ubuntu's suExec is compiled with /var/www as Doc_Root . Run

/usr/lib/apache2/suexec -V


and the output should look like this:

root@server1:~# /usr/lib/apache2/suexec -V
 -D AP_DOC_ROOT="/var/www"
 -D AP_GID_MIN=100
 -D AP_HTTPD_USER="www-data"
 -D AP_LOG_EXEC="/var/log/apache2/suexec.log"
 -D AP_SAFE_PATH="/usr/local/bin:/usr/bin:/bin"
 -D AP_UID_MIN=100
 -D AP_USERDIR_SUFFIX="public_html"
root@server1:~#


So if you want to use suExec with ISPconfig, don't change the default web root (which is /var/www ) if you use expert mode during the ISPConfig installation (in standard mode you can't change the web root anyway so you'll be able to use suExec in any case).
