The Perfect Server – Debian Wheezy (Apache2, BIND, Dovecot, ISPConfig 3)


This tutorial shows how to prepare a Debian Wheezy server (with Apache2, BIND, Dovecot) 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 or nginx web server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This setup covers Apache (instead of nginx), BIND (instead of MyDNS), and Dovecot (instead of Courier).

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 will work for you!

 

1 Requirements

To install such a system you will need the following:

  • the Debian Wheezy network installation CD, available here: http://cdimage.debian.org/debian-cd/7.0.0/i386/iso-cd/debian-7.0.0-i386-netinst.iso (i386) or http://cdimage.debian.org/debian-cd/7.0.0/amd64/iso-cd/debian-7.0.0-amd64-netinst.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 Debian Wheezy network installation CD into your system and boot from it. Select Install (this will start the text installer – if you prefer a graphical installer, select Graphical install):

1

Choose your language:

2

Then select your location:

3

4

5

If you’ve selected an uncommon combination of language and location (like English as the language and Germany as the location, as in my case), the installer might tell you that there is no locale defined for this combination; in this case you have to select the locale manually. I select en_US.UTF-8 here:

6

Choose a keyboard layout:

7

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

8

9

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

10

Enter your domain name. In this example, this is example.com:

11

Afterwards, give the root user a password:

12

Confirm that password to avoid typos:

13

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

14

15

16

17

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).

19

Select the disk that you want to partition:

20

Then select the partitioning scheme. As mentioned before, I select All files in one partition (recommended for new users) for simplicity’s sake – it’s up to your likings what you choose here:

21

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

22

When you’re finished, select Finish partitioning and write changes to disk:

23

Select Yes when you’re asked Write changes to disks?:

24

Afterwards, your new partitions are created and formatted.

Now the base system is installed:

25

Next you must configure apt. Because you are using the Debian Wheezy Netinstall CD which contains only a minimal set of packages, you must use a network mirror. Select the country where the network mirror that you want to use is located (usually this is the country where your Debian Wheezy system is located):

26

Then select the mirror you want to use (e.g. ftp.de.debian.org):

27

Unless you use an HTTP proxy, leave the following field empty and hit Continue:

28

Apt is now updating its packages database:

29

You can skip the package usage survey by selecting No:

31

We need a web server, DNS server, mail server, and a MySQL database, 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. Therefore we just select Standard system utilities and SSH server (so that I can immediately connect to the system with an SSH client such as PuTTY after the installation has finished) and hit Continue:

32

The required packages are downloaded and installed on the system:

33

34

When you’re asked Install the GRUB boot loader to the master boot record?, select Yes:

35

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

36

On to the next step…

4 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 Debian Wheezy server and follow the remaining steps from this tutorial.

 

5 Install vim-nox (Optional)

I’ll use vi as my text editor in this tutorial. The default vi program has some strange behaviour on Debian and Ubuntu; to fix this, we install vim-nox:

apt-get install vim-nox

(You don’t have to do this if you use a different text editor such as joe or nano.)

 

6 Configure The Network

Because the Debian Wheezy 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) (please note that I replace allow-hotplug eth0 with auto eth0; otherwise restarting the network doesn’t work, and we’d have to reboot the whole system):

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
#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 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
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Now run

echo server1.example.com > /etc/hostname
/etc/init.d/hostname.sh start

Afterwards, run

hostname
hostname -f

It is important that both show server1.example.com now!

 

7 Update Your Debian Installation

First make sure that your /etc/apt/sources.list contains the wheezy-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), and that the contrib and non-free repositories are enabled (some packages such as libapache2-mod-fastcgi are not in the main repository).

vi /etc/apt/sources.list

deb http://ftp.de.debian.org/debian/ wheezy main contrib non-free
deb-src http://ftp.de.debian.org/debian/ wheezy main contrib non-free

deb http://security.debian.org/ wheezy/updates main contrib non-free
deb-src http://security.debian.org/ wheezy/updates main contrib non-free

# wheezy-updates, previously known as 'volatile'
deb http://ftp.de.debian.org/debian/ wheezy-updates main contrib non-free
deb-src http://ftp.de.debian.org/debian/ wheezy-updates main contrib non-free

Run

apt-get update

to update the apt package database and

apt-get upgrade

to install the latest updates (if there are any).

 

8 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

Use dash as the default system shell (/bin/sh)? <- no

If you don’t do this, the ISPConfig installation will fail.

 

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

and your system time will always be in sync.

 

10 Install Postfix, Dovecot, MySQL, phpMyAdmin, rkhunter, binutils

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

apt-get install postfix postfix-mysql postfix-doc mysql-client mysql-server openssl getmail4 rkhunter binutils dovecot-imapd dovecot-pop3d dovecot-mysql dovecot-sieve sudo

You will be asked the following questions:

General type of mail configuration: <– Internet Site
System mail name: <– server1.example.com
New password for the MySQL “root” user: <– yourrootsqlpassword
Repeat password for the MySQL “root” user: <– yourrootsqlpassword

Next open the TLS/SSL and submission ports in Postfix:

vi /etc/postfix/master.cf

Uncomment the submission and smtps sections as follows (leave -o milter_macro_daemon_name=ORIGINATING as we don’t need it):

[...]
submission inet n       -       -       -       -       smtpd
  -o syslog_name=postfix/submission
  -o smtpd_tls_security_level=encrypt
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
#  -o milter_macro_daemon_name=ORIGINATING
smtps     inet  n       -       -       -       -       smtpd
  -o syslog_name=postfix/smtps
  -o smtpd_tls_wrappermode=yes
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
#  -o milter_macro_daemon_name=ORIGINATING
[...]

Restart Postfix afterwards:

/etc/init.d/postfix restart

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      26757/mysqld
root@server1:~#

 

11 Install Amavisd-new, SpamAssassin, And Clamav

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

apt-get 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

The ISPConfig 3 setup uses amavisd which loads the SpamAssassin filter library internally, so we can stop SpamAssassin to free up some RAM:

/etc/init.d/spamassassin stop
update-rc.d -f spamassassin remove

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

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

apt-get 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 libruby libapache2-mod-ruby libapache2-mod-python php5-curl php5-intl php5-memcache php5-memcached php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl memcached

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

Next open /etc/apache2/mods-available/suphp.conf

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

… and comment out the <FilesMatch “\.ph(p3?|tml)$”> section and add the line AddType application/x-httpd-suphp .php .php3 .php4 .php5 .phtml – otherwise all PHP files will be run by SuPHP:

<IfModule mod_suphp.c>
    #<FilesMatch "\.ph(p3?|tml)$">
    #    SetHandler application/x-httpd-suphp
    #</FilesMatch>
        AddType application/x-httpd-suphp .php .php3 .php4 .php5 .phtml
        suPHP_AddHandler application/x-httpd-suphp

    <Directory />
        suPHP_Engine on
    </Directory>

    # By default, disable suPHP for debian packaged web applications as files
    # are owned by root and cannot be executed by suPHP because of min_uid.
    <Directory /usr/share>
        suPHP_Engine off
    </Directory>

# # Use a specific php config file (a dir which contains a php.ini file)
#       suPHP_ConfigPath /etc/php5/cgi/suphp/
# # Tells mod_suphp NOT to handle requests with the type <mime-type>.
#       suPHP_RemoveHandler <mime-type>
</IfModule>

Restart Apache afterwards:

/etc/init.d/apache2 restart

If you want to host Ruby files with the extension .rb on your web sites created through ISPConfig, you must comment out the line application/x-ruby rb in /etc/mime.types:

vi /etc/mime.types

[...]
#application/x-ruby                             rb
[...]

(This is needed only for .rb files; Ruby files with the extension .rbx work out of the box.)

Restart Apache afterwards:

/etc/init.d/apache2 restart

 

12.1 Xcache

Xcache is a free and open PHP opcode cacher for caching and optimizing PHP intermediate code. It’s similar to other PHP opcode cachers, such as eAccelerator and APC. It is strongly recommended to have one of these installed to speed up your PHP page.

Xcache can be installed as follows:

apt-get install php5-xcache

Now restart Apache:

/etc/init.d/apache2 restart

 

12.2 PHP-FPM

Starting with ISPConfig 3.0.5, there is an additional PHP mode that you can select for usage with Apache: PHP-FPM.

To use PHP-FPM with Apache, we need the mod_fastcgi Apache module (please don’t mix this up with mod_fcgid – they are very similar, but you cannot use PHP-FPM with mod_fcgid). We can install PHP-FPM and mod_fastcgi as follows:

apt-get install libapache2-mod-fastcgi php5-fpm

Make sure you enable the module and restart Apache:

a2enmod actions fastcgi alias
/etc/init.d/apache2 restart

 

12.3 Additional PHP Versions

Starting with ISPConfig 3.0.5, it is possible to have multiple PHP versions on one server (selectable through ISPConfig) which can be run through FastCGI and PHP-FPM. To learn how to build additional PHP versions (PHP-FPM and FastCGI) and how to configure ISPConfig, please check this tutorial: How To Use Multiple PHP Versions (PHP-FPM & FastCGI) With ISPConfig 3 (Debian Wheezy).

 

13 Install Mailman

Since version 3.0.4, ISPConfig also allows you to manage (create/modify/delete) Mailman mailing lists. If you want to make use of this feature, install Mailman as follows:

apt-get install mailman

Select at least one language, e.g.:

Languages to support: <– en (English)
Missing site list <– Ok

Before we can start Mailman, a first mailing list called mailman must be created:

newlist mailman

root@server1:~# newlist mailman
Enter the email of the person running the list: <– admin email address, e.g. listadmin@example.com
Initial mailman password: <– admin password for the mailman list
To finish creating your mailing list, you must edit your /etc/aliases (or
equivalent) file by adding the following lines, and possibly running the
`newaliases’ program:

## mailman mailing list
mailman:              “|/var/lib/mailman/mail/mailman post mailman”
mailman-admin:        “|/var/lib/mailman/mail/mailman admin mailman”
mailman-bounces:      “|/var/lib/mailman/mail/mailman bounces mailman”
mailman-confirm:      “|/var/lib/mailman/mail/mailman confirm mailman”
mailman-join:         “|/var/lib/mailman/mail/mailman join mailman”
mailman-leave:        “|/var/lib/mailman/mail/mailman leave mailman”
mailman-owner:        “|/var/lib/mailman/mail/mailman owner mailman”
mailman-request:      “|/var/lib/mailman/mail/mailman request mailman”
mailman-subscribe:    “|/var/lib/mailman/mail/mailman subscribe mailman”
mailman-unsubscribe:  “|/var/lib/mailman/mail/mailman unsubscribe mailman”

Hit enter to notify mailman owner… <– ENTER

root@server1:~#

Open /etc/aliases afterwards…

vi /etc/aliases

… and add the following lines:

[...]
## mailman mailing list
mailman:              "|/var/lib/mailman/mail/mailman post mailman"
mailman-admin:        "|/var/lib/mailman/mail/mailman admin mailman"
mailman-bounces:      "|/var/lib/mailman/mail/mailman bounces mailman"
mailman-confirm:      "|/var/lib/mailman/mail/mailman confirm mailman"
mailman-join:         "|/var/lib/mailman/mail/mailman join mailman"
mailman-leave:        "|/var/lib/mailman/mail/mailman leave mailman"
mailman-owner:        "|/var/lib/mailman/mail/mailman owner mailman"
mailman-request:      "|/var/lib/mailman/mail/mailman request mailman"
mailman-subscribe:    "|/var/lib/mailman/mail/mailman subscribe mailman"
mailman-unsubscribe:  "|/var/lib/mailman/mail/mailman unsubscribe mailman"

Run

newaliases

afterwards and restart Postfix:

/etc/init.d/postfix restart

Finally we must enable the Mailman Apache configuration:

ln -s /etc/mailman/apache.conf /etc/apache2/conf.d/mailman.conf

This defines the alias /cgi-bin/mailman/ for all Apache vhosts, which means you can access the Mailman admin interface for a list at http:///cgi-bin/mailman/admin/, and the web page for users of a mailing list can be found at http:///cgi-bin/mailman/listinfo/.

Under http:///pipermail you can find the mailing list archives.

Restart Apache afterwards:

/etc/init.d/apache2 restart

Then start the Mailman daemon:

/etc/init.d/mailman start

 

14 Install PureFTPd And Quota

PureFTPd and quota can be installed with the following command:

apt-get 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' 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).
#
#                
/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=46d1bd79-d761-4b23-80b8-ad20cb18e049 /boot           ext2    defaults        0       2
/dev/mapper/server1-swap_1 none            swap    sw              0       0
/dev/sr0        /media/cdrom0   udf,iso9660 user,noauto     0       0

To enable quota, run these commands:

mount -o remount /

quotacheck -avugm
quotaon -avug

 

15 Install BIND DNS Server

BIND can be installed as follows:

apt-get install bind9 dnsutils

 

16 Install Vlogger, Webalizer, And AWstats

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

apt-get install vlogger webalizer awstats geoip-database libclass-dbi-mysql-perl

Open /etc/cron.d/awstats afterwards…

vi /etc/cron.d/awstats

… and comment out everything in that file:

#MAILTO=root

#*/10 * * * * www-data [ -x /usr/share/awstats/tools/update.sh ] && /usr/share/awstats/tools/update.sh

# Generate static reports:
#10 03 * * * www-data [ -x /usr/share/awstats/tools/buildstatic.sh ] && /usr/share/awstats/tools/buildstatic.sh

 

17 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!):

apt-get install build-essential autoconf automake1.9 libtool flex bison debhelper binutils-gold

cd /tmp
wget http://olivier.sessink.nl/jailkit/jailkit-2.17.tar.gz
tar xvfz jailkit-2.17.tar.gz
cd jailkit-2.17
./debian/rules binary

You can now install the Jailkit .deb package as follows:

cd ..
dpkg -i jailkit_2.17-1_*.deb
rm -rf jailkit-2.17*

 

18 Install fail2ban

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

apt-get install fail2ban

To make fail2ban monitor PureFTPd and Dovecot, create the file /etc/fail2ban/jail.local:

vi /etc/fail2ban/jail.local

 

[pureftpd]
enabled  = true
port     = ftp
filter   = pureftpd
logpath  = /var/log/syslog
maxretry = 3

[dovecot-pop3imap]
enabled = true
filter = dovecot-pop3imap
action = iptables-multiport[name=dovecot-pop3imap, port="pop3,pop3s,imap,imaps", protocol=tcp]
logpath = /var/log/mail.log
maxretry = 5

[sasl]
enabled  = true
port     = smtp
filter   = sasl
logpath  = /var/log/mail.log
maxretry = 3

Then create the following two filter files:

vi /etc/fail2ban/filter.d/pureftpd.conf

[Definition]
failregex = .*pure-ftpd: \(.*@<HOST>\) \[WARNING\] Authentication failed for user.*
ignoreregex =

vi /etc/fail2ban/filter.d/dovecot-pop3imap.conf

[Definition]
failregex = (?: pop3-login|imap-login): .*(?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed|Aborted login \(\d+ authentication attempts).*rip=(?P<host>\S*),.*
ignoreregex =

Restart fail2ban afterwards:

/etc/init.d/fail2ban restart

19 Install SquirrelMail

To install the SquirrelMail webmail client, run

apt-get install squirrelmail

Then configure SquirrelMail:

squirrelmail-configure

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

SquirrelMail Configuration : Read: config.php (1.4.0)

While we have been building SquirrelMail, we have discovered some
preferences that work better with some servers that don’t work so
well with others.  If you select your IMAP server, this option will
set some pre-defined settings for that server.

Please note that you will still need to go through and make sure

SquirrelMail Configuration : Read: config.php
———————————————————
While we have been building SquirrelMail, we have discovered some
preferences that work better with some servers that don’t work so
well with others.  If you select your IMAP server, this option will
set some pre-defined settings for that server.

Please note that you will still need to go through and make sure
everything is correct.  This does not change everything.  There are
only a few settings that this will change.

Now we will configure SquirrelMail so that you can use it from within your web sites (created through ISPConfig) by using the /squirrelmail or /webmail aliases. So if your website is www.example.com, you will be able to access SquirrelMail using www.example.com/squirrelmail or www.example.com/webmail.

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

Now open /etc/apache2/conf.d/squirrelmail.conf

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

… and add the following lines to the container that make sure that mod_php is used for accessing SquirrelMail, regardless of what PHP mode you select for your website in ISPConfig:

 

[...]
<Directory /usr/share/squirrelmail>
  Options FollowSymLinks
  <IfModule mod_php5.c>
    AddType application/x-httpd-php .php
    php_flag magic_quotes_gpc Off
    php_flag track_vars On
    php_admin_flag allow_url_fopen Off
    php_value include_path .
    php_admin_value upload_tmp_dir /var/lib/squirrelmail/tmp
    php_admin_value open_basedir /usr/share/squirrelmail:/etc/squirrelmail:/var/lib/squirrelmail:/etc/hostname:/etc/mailname
    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>
[...]

mkdir /var/lib/squirrelmail/tmpCreate the directory /var/lib/squirrelmail/tmp

… and make it owned by the user www-data:

chown www-data /var/lib/squirrelmail/tmp

Reload Apache again:

/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.

You can now access SquirrelMail from your web site as follows:

http://192.168.0.100/squirrelmail
http://www.example.com/squirrelmail

You can also access it from the ISPConfig control panel vhost (after you have installed ISPConfig, see the next chapter) 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
[...]

Then reload Apache:

/etc/init.d/apache2 reload

Now you can access Squirrelmail as follows:

http://192.168.0.100/webmail
http://www.example.com/webmail
http://server1.example.com:8080/webmail
(after you have installed ISPConfig, see the next chapter)

37

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 *:80>
  DocumentRoot /usr/share/squirrelmail
  ServerName webmail.example.com
</VirtualHost>

/etc/init.d/apache2 reload Now reload Apache… 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!).

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

 

20 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/

The next step is to run

php -q install.php

This will start the ISPConfig 3 installer. The installer will configure all services like Postfix, Dovecot, 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
PHP Deprecated:  Comments starting with ‘#’ are deprecated in /etc/php5/cli/conf.d/ming.ini on line 1 in Unknown on line 0

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

You now also have the possibility to let the installer create an SSL vhost for the ISPConfig control panel, so that ISPConfig can be accessed using https:// instead of http://. To achieve this, just press ENTER when you see this question: Do you want a secure (SSL) connection to the ISPConfig web interface (y,n) [y]:.

Afterwards you can access ISPConfig 3 under http(s)://server1.example.com:8080/ or http(s)://192.168.0.100:8080/ ( http or https depends on what you chose during installation). 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.

 

 

21 Additional Notes

21.1 OpenVZ

If the Debian 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
