This tutorial shows how to install an Ubuntu 14.10 (Utopic Unicorn) 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 the installation of Apache (instead of nginx), BIND (instead of MyDNS), and Dovecot (instead of Courier).if(typeof __ez_fad_position != ‘undefined’){__ez_fad_position(‘div-gpt-ad-howtoforge_com-medrectangle-3-0’)};
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 192.168.0.100 and the gateway 192.168.0.1 . 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 14.10 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:
nano /etc/apt/sources.list# # deb cdrom:[Ubuntu-Server 14.10 _Utopic Unicorn_ - Release amd64 (20141022.2)]/ utopic main restricted #deb cdrom:[Ubuntu-Server 14.10 _Utopic Unicorn_ - Release amd64 (20141022.2)]/ utopic main restricted # See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to # newer versions of the distribution. deb http://de.archive.ubuntu.com/ubuntu/ utopic main restricted deb-src http://de.archive.ubuntu.com/ubuntu/ utopic main restricted ## Major bug fix updates produced after the final release of the ## distribution. deb http://de.archive.ubuntu.com/ubuntu/ utopic-updates main restricted deb-src http://de.archive.ubuntu.com/ubuntu/ utopic-updates main restricted ## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu ## team.

Then run
apt-get updateto update the apt package database and
apt-get upgradeto 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
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:if(typeof __ez_fad_position != ‘undefined’){__ez_fad_position(‘div-gpt-ad-howtoforge_com-medrectangle-4-0’)};
dpkg-reconfigure dashUse 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. Simply run
apt-get install ntp ntpdateand your system time will always be in sync.
6. Install Postfix, Dovecot, MySQL, phpMyAdmin, rkhunter, binutils
For installing postfix we need to stop and remove sendmail
service sendmail stop; update-rc.d -f sendmail removeNow we can install Postfix, Dovecot, MySQL, 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 sudoYou will be asked the following questions:
New password for the MySQL “root” user: <– yourrootsqlpassword
Repeat password for the MySQL “root” user: <– yourrootsqlpassword
Create a self-signed SSL certificate?: <– Yes
Host name: <– server1.example.com
Local only: <– OK
General type of mail configuration: <– Internet Site
System mail name: <– server1.example.com
Next open the TLS/SSL and submission ports in Postfix:
nano /etc/postfix/master.cfUncomment 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 restartWe 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:
nano /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:
service mysql restartNow check that networking is enabled. Run
netstat -tap | grep mysqlThe output should look like this:
[email protected]:~# netstat -tap | grep mysql
tcp 0 0 *:mysql *:* LISTEN 24603/mysqld
[email protected]:~# 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-perlThe 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 removeTo Run clamav use
freshclam
service clamav-daemon start
