This tutorial shows the installation of an Ubuntu 15.04 (Vivid Vervet) web hosting server server with Apache2, Postfix, Dovecot, Bind and PureFTPD to prepare it for the installation of ISPConfig 3. The resulting system will provide a Web, Mail, Mailinglist, DNS and FTP Server.
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 the installation of Apache (instead of nginx), BIND (instead of MyDNS), and Dovecot (instead of Courier).
ISPConfig 3 Manual
In order to learn how to use ISPConfig 3, I strongly recommend to download the ISPConfig 3 Manual.
On more than 300 pages, it covers the concept behind ISPConfig (admin, resellers, clients), explains how to install and update ISPConfig 3, includes a reference for all forms and form fields in ISPConfig together with examples of valid inputs, and provides tutorials for the most common tasks in ISPConfig 3. It also lines out how to make your server more secure and comes with a troubleshooting section at the end.
1. Preliminary Note
In this tutorial I use the hostname server1.example.com with the IP address 192.168.1.100 and the gateway 192.168.1.1 . These settings might differ for you, so you have to replace them where appropriate. Before proceeding further you need to have a basic minimal installation of Ubuntu 15.04 as explained in tutorial.
2. 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 afterwards:

to update the apt package database and
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:
3. Change The Default Shell
/bin/sh is a symlink to /bin/dash, however we need /bin/bash, not /bin/dash. Therefore we do this:
Use dash as the default system shell (/bin/sh)? <-- No
If you don't do this, the ISPConfig installation will fail.
4. 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:
service apparmor stop
update-rc.d -f apparmor remove
apt-get remove apparmor apparmor-utils
5. Synchronize the System Clock
It is a good idea to synchronize the system clock with an NTP (network time protocol) server over the Internet when you run a physical server. In case you run a virtual server then you should skip this step. Just run
apt-get install ntp ntpdate
and your system time will always be in sync.
6. Install Postfix, Dovecot, MariaDB, phpMyAdmin, rkhunter, binutils
For installing postfix we need to ensure that sendmail is not installed and running. To stop and remove sendmail run this command:
service sendmail stop; update-rc.d -f sendmail remove
The error message:
Failed to stop sendmail.service: Unit sendmail.service not loaded.
Is ok, it just means that sendmail was not installed, so there was nothing to be removed.
Now we can install Postfix, Dovecot, MariaDB (as MySQL replacement), rkhunter, and binutils with a single command:
apt-get install postfix postfix-mysql postfix-doc mariadb-client mariadb-server openssl getmail4 rkhunter binutils dovecot-imapd dovecot-pop3d dovecot-mysql dovecot-sieve sudo
You will be asked the following questions:
Create a self-signed SSL certificate? <-- yes
Host name: <-- server1.example.com
General type of mail configuration: <-- Internet Site
System mail name: <-- server1.example.com
Next open the TLS/SSL and submission ports in Postfix:
Uncomment the submission and smtps sections as follows - add the line -o smtpd_client_restrictions=permit_sasl_authenticated,reject to both sections and leave everything thereafter commented:
[...] 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 smtpd_reject_unlisted_recipient=no # -o smtpd_client_restrictions=$mua_client_restrictions # -o smtpd_helo_restrictions=$mua_helo_restrictions # -o smtpd_sender_restrictions=$mua_sender_restrictions # -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject # -o milter_macro_daemon_name=ORIGINATING smtps inet n - - - - smtpd -o syslog_name=postfix/smtps -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject # -o smtpd_reject_unlisted_recipient=no # -o smtpd_client_restrictions=$mua_client_restrictions # -o smtpd_helo_restrictions=$mua_helo_restrictions # -o smtpd_sender_restrictions=$mua_sender_restrictions # -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject # -o milter_macro_daemon_name=ORIGINATING [...]
Restart Postfix afterwards:
service 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:
[...] # 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 [...]
Now we set a root password in MariaDB. Run:
You will be asked these questions:
Enter current password for root (enter for none): <-- press enter
Set root password? [Y/n] <-- y
New password: <-- Enter the new MariaDB root password here
Re-enter new password: <-- Repeat the password
Remove anonymous users? [Y/n] <-- y
Disallow root login remotely? [Y/n] <-- y
Reload privilege tables now? [Y/n] <-- y
Then we restart MariaDB:
service mysql restart
Now check that networking is enabled. Run
netstat -tap | grep mysql
The output should look like this:
7. 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:
service spamassassin stop
update-rc.d -f spamassassin remove
Edit the clamd configuration file:
and change the line:
And save the file. To start clamav use
service clamav-daemon start
