You have to install the system requirements for ISPConfig first as described in the perfect server guides. The installation instructions can be found here:
https://www.ispconfig.org/documentation/If you use Raspbian, then one of the Debian guides should probably work.
https://www.howtoforge.com/tutorial/perf...-and-ispconfig/https://www.howtoforge.com/tutorial/perf...-and-ispconfig/The Perfect Server - Ubuntu 18.04 (Bionic Beaver) with Apache, PHP, MySQL, PureFTPD, BIND, Postfix, Dovecot and ISPConfig 3.1
This tutorial shows the installation of an Ubuntu 18.04 (Bionic Beaver) web hosting server with Apache 2.4, Postfix, Dovecot, Bind and PureFTPD to prepare it for the installation of ISPConfig 3.1. The resulting system will provide a Web, Mail, Mailinglist, DNS and FTP Server.
ISPConfig is a web hosting 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).
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 18.04 as explained in the tutorial.
The commands in this tutorial have to be run with root permissions. To avoid adding sudo in front of each command, you'll have to become root user by running:
sudo -s
before you proceed.
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:
nano /etc/apt/sources.list
#
# deb cdrom:[Ubuntu-Server 18.04 LTS _Bionic Beaver_ - Release amd64 (20180425.1)]/ bionic main restricted

http://security.ubuntu.com/ubuntu bionic-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). 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:
dpkg-reconfigure dash
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 -y install ntp
and your system time will always be in sync.
6. Install Postfix, Dovecot, MariaDB, rkhunter, and 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 -y install postfix postfix-mysql postfix-doc mariadb-client mariadb-server openssl getmail4 rkhunter binutils dovecot-imapd dovecot-pop3d dovecot-mysql dovecot-sieve dovecot-lmtpd sudo
You will be asked the following questions:
General type of mail configuration: <-- Internet Site
System mail name: <-- server1.example.com
It is important that you use a subdomain as "system mail name" like server1.example.com or server1.yourdomain.com and not a domain that you want to use as email domain (e.g. yourdomain.tld) later.
Next, open the TLS/SSL and submission ports in Postfix:
nano /etc/postfix/master.cf
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 - y - - 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=$mua_sender_restrictions
# -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject
# -o milter_macro_daemon_name=ORIGINATING
smtps inet n - y - - smtpd
-o syslog_name=postfix/smtps
-o smtpd_tls_wrappermode=yes
-o smtpd_sasl_auth_enable=yes
-o smtpd_client_restrictions=permit_sasl_authenticated,reject
# -o smtpd_reject_unlisted_recipient=no
# -o smtpd_client_restrictions=$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
[...]
NOTE: The whitespaces in front of the "-o .... " lines are important!
Restart Postfix afterward:
service postfix restart
We want MySQL to listen on all interfaces, not just localhost. Therefore, we edit /etc/mysql/mariadb.conf.d/50-server.cnf and comment out the line bind-address = 127.0.0.1:
nano /etc/mysql/mariadb.conf.d/50-server.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
[...]
Now we set a root password in MariaDB. Run:
mysql_secure_installation
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
Set the password authentication method in MariaDB to native so we can use PHPMyAdmin later to connect as root user:
echo "update mysql.user set plugin = 'mysql_native_password' where user='root';" | mysql -u root
Edit the file /etc/mysql/debian.cnf and set the MYSQL / MariaDB root password there twice in the rows that start with password.
nano /etc/mysql/debian.cnf
The MySQL root password that needs to be added is shown in read, in this example the password is "howtoforge". Replace the word "howtoforge" with the password that you have set for the MySQL root user with the mysql_secure_installation command.
# Automatically generated for Debian scripts. DO NOT TOUCH!
[client]
host = localhost
user = root
password = howtoforge
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host = localhost
user = root
password = howtoforge
socket = /var/run/mysqld/mysqld.sock
basedir = /usr
Then we restart MariaDB:
service mysql restart
Now check that networking is enabled. Run
Advertisements
netstat -tap | grep mysql
The output should look like this:
root@server1:~# netstat -tap | grep mysql
tcp6 0 0 [::]:mysql [::]:* LISTEN 30591/mysqld
root@server1:~#
7. Install Amavisd-new, SpamAssassin, and Clamav
To install amavisd-new, SpamAssassin, and ClamAV, we run
apt-get -y install amavisd-new spamassassin clamav clamav-daemon 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 libdbd-mysql-perl postgrey
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
To start ClamAV use:
freshclam
service clamav-daemon start
The following error can be ignored on the first run of freshclam.
ERROR: /var/log/clamav/freshclam.log is locked by another process
ERROR: Problem with internal logger (UpdateLogFile = /var/log/clamav/freshclam.log).
The amavisd-new program has currently a bug in Ubuntu 18.04 which prevents that emails get signed with Dkim correctly. Run the following commands to patch amavisd-new.
cd /tmp
wget
https://git.ispconfig.org/ispconfig/ispc...-new-2.11.patchcd /usr/sbin
cp -pf amavisd-new amavisd-new_bak
patch < /tmp/ubuntu-amavisd-new-2.11.patch
In case you get an error for thelast 'patch' command, then Ubuntu has probably fixed the issue in the meantime, so it should be safe to ignore that error then.
7.1 Install Metronome XMPP Server (optional)
The Metronome XMPP Server provides an XMPP chat server. This step is optional, if you do not need a chat server, then you can skip this step. No other ISPConfig functions depend on this software.
Install the following packages with apt.
apt-get -y install git lua5.1 liblua5.1-0-dev lua-filesystem libidn11-dev libssl-dev lua-zlib lua-expat lua-event lua-bitop lua-socket lua-sec luarocks luarocks
luarocks install lpc
Add a shell user for Metronome.
adduser --no-create-home --disabled-login --gecos 'Metronome' metronome
Download Metronome to the /opt directory and compile it.
cd /opt; git clone
https://github.com/maranda/metronome.git metronome
cd ./metronome; ./configure --ostype=debian --prefix=/usr
make
make install
Metronome has now be installed to /opt/metronome.
8. Install Apache, PHP, phpMyAdmin, FCGI, SuExec, Pear, and mcrypt
Apache 2.4, PHP 7.2, phpMyAdmin, FCGI, suExec, and Pear can be installed as follows:
apt-get -y install apache2 apache2-doc apache2-utils libapache2-mod-php php7.2 php7.2-common php7.2-gd php7.2-mysql php7.2-imap phpmyadmin php7.2-cli php7.2-cgi libapache2-mod-fcgid apache2-suexec-pristine php-pear mcrypt imagemagick libruby libapache2-mod-python php7.2-curl php7.2-intl php7.2-pspell php7.2-recode php7.2-sqlite3 php7.2-tidy php7.2-xmlrpc php7.2-xsl memcached php-memcache php-imagick php-gettext php7.2-zip php7.2-mbstring php-soap php7.2-soap
You will see the following question:
Web server to reconfigure automatically: <-- apache2
Configure database for phpmyadmin with dbconfig-common? <-- Yes
MySQL application password for phpmyadmin: <-- Press enter
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 cgi
a2enmod dav_fs dav auth_digest headers
To ensure that the server cannot be attacked through the HTTPOXY vulnerability, I will disable the HTTP_PROXY header in apache globally. Create a new httpoxy.conf file with nano:
nano /etc/apache2/conf-available/httpoxy.conf
Paste this content into the file:
<IfModule mod_headers.c>
RequestHeader unset Proxy early
</IfModule>
Enable the config file by running:
a2enconf httpoxy
Restart Apache afterward:
service apache2 restart
If you want to host Ruby files with the extension .rb on your websites created through ISPConfig, you must comment out the line application/x-ruby rb in /etc/mime.types:
nano /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:
service apache2 restart
8.1 PHP Opcode cache (optional)
Opcache is a free PHP opcode cacher for caching and optimizing PHP intermediate code. APCu is a compatibility module which provides APC compatible functions for Opcache which is used by many CMS caching systems. It is recommended to have these PHP extensions installed to speed up your PHP page.
APCu can be installed as follows:
apt-get -y install php7.2-opcache php-apcu
Now restart Apache:
service apache2 restart
8.2 PHP-FPM
To use PHP-FPM with Apache, we need the mod_proxy_fcgi Apache module, which is installed by default and needs just be enabled. We can install PHP-FPM and as follows:
apt-get -y install php7.2-fpm
Make sure you enable the modules and restart Apache:
a2enmod actions proxy_fcgi alias
service apache2 restart
10.1 Install HHVM (HipHop Virtual Machine), optional
In this step, we will install HHVM with apt. HHVM is a fast PHP engine developed by Facebook.
apt-get -y install hhvm
9. Install Let's Encrypt
ISPConfig 3.1 has built-in support for the free SSL Certificate Authority Let's encrypt. The Let's Encrypt function allows you to create free SSL Certificates for your website in ISPConfig.
Now we will add support for Let's encrypt.
apt-get -y install certbot
10. Install Mailman
ISPConfig 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 -y install mailman
Select at least one language, e.g.:
Languages to support: <-- en (English)
Missing site list <-- Ok
The error 'Job for mailman.service failed because the control process exited with error code.' can be ignored for now.
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...
nano /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
afterward and restart Postfix:
service postfix restart
Finally, we must enable the Mailman Apache configuration:
ln -s /etc/mailman/apache.conf /etc/apache2/conf-available/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://<vhost>/cgi-bin/mailman/admin/<listname>, and the web page for users of a mailing list can be found at http://<vhost>/cgi-bin/mailman/listinfo/<listname>.
Under http://<vhost>/pipermail you can find the mailing list archives.
Activate the configuration with:
a2enconf mailman
Restart Apache afterward:
service apache2 restart
Then start the Mailman daemon:
service mailman start
11. Install PureFTPd and Quota
PureFTPd and quota can be installed with the following command:
Advertisements
apt-get -y install pure-ftpd-common pure-ftpd-mysql quota quotatool
Edit the file /etc/default/pure-ftpd-common...
nano /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:
service 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 /):
nano /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).
#
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/mapper/server1--vg-root / ext4 errors=remount-ro,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 0 1
/dev/mapper/server1--vg-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
Which will show the following output:
root@server1:/opt/metronome# quotacheck -avugm
quotacheck: Scanning /dev/mapper/server1--vg-root [/] done
quotacheck: Cannot stat old user quota file //quota.user: No such file or directory. Usage will not be subtracted.
quotacheck: Cannot stat old group quota file //quota.group: No such file or directory. Usage will not be subtracted.
quotacheck: Cannot stat old user quota file //quota.user: No such file or directory. Usage will not be subtracted.
quotacheck: Cannot stat old group quota file //quota.group: No such file or directory. Usage will not be subtracted.
quotacheck: Checked 13602 directories and 96597 files
quotacheck: Old file not found.
quotacheck: Old file not found.
root@server1:/opt/metronome# quotaon -avug
/dev/mapper/server1--vg-root [/]: group quotas turned on
/dev/mapper/server1--vg-root [/]: user quotas turned on
12. Install BIND DNS Server
BIND can be installed as follows:
apt-get -y install bind9 dnsutils haveged
Enable and start the haveged Daemon:
systemctl enable haveged
systemctl start haveged
13. Install Vlogger, Webalizer, and AWStats
Vlogger, Webalizer, and AWStats can be installed as follows:
apt-get -y install vlogger webalizer awstats geoip-database libclass-dbi-mysql-perl
Open /etc/cron.d/awstats afterwards...
nano /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
14. 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 -y install build-essential autoconf automake1.11 libtool flex bison debhelper binutils
cd /tmp
wget
http://olivier.sessink.nl/jailkit/jailkit-2.19.tar.gztar xvfz jailkit-2.19.tar.gz
cd jailkit-2.19
echo 5 > debian/compat
Then build the jailkit package by running this command:
./debian/rules binary
You can now install the Jailkit .deb package as follows:
cd ..
dpkg -i jailkit_2.19-1_*.deb
rm -rf jailkit-2.19*
15. Install fail2ban and UFW
This is optional but recommended, because the ISPConfig monitor tries to show the log:
apt-get -y install fail2ban
To make fail2ban monitor PureFTPd and Dovecot, create the file /etc/fail2ban/jail.local:
nano /etc/fail2ban/jail.local
[pure-ftpd]
enabled = true
port = ftp
filter = pure-ftpd
logpath = /var/log/syslog
maxretry = 3
[dovecot]
enabled = true
filter = dovecot
action = iptables-multiport[name=dovecot-pop3imap, port="pop3,pop3s,imap,imaps", protocol=tcp]
logpath = /var/log/mail.log
maxretry = 5
[postfix]
enabled = true
port = smtp
filter = postfix
logpath = /var/log/mail.log
maxretry = 3
Restart fail2ban afterwards:
service fail2ban restart
To install the UFW firewall, run this apt command:
apt-get install ufw
16. Install Roundcube Webmail
To install Roundcube Webmail, run:
apt-get -y install roundcube roundcube-core roundcube-mysql roundcube-plugins javascript-common libjs-jquery-mousewheel php-net-sieve tinymce
The installer will ask the following questions:
Configure database for roundcube with dbconfig-common? <-- Yes
MySQL application password for roundcube: <-- Press enter
Then edit the RoundCube apache configuration file.
nano /etc/apache2/conf-enabled/roundcube.conf
and remove the # in front of the Alias line, then add the second Alias line for /webmail and add the line "AddType application/x-httpd-php .php" right after the "<Directory /var/lib/roundcube>" line:
# Those aliases do not work properly with several hosts on your apache server
# Uncomment them to use it or adapt them to your configuration
Alias /roundcube /var/lib/roundcube
Alias /webmail /var/lib/roundcube
[...]
<Directory /var/lib/roundcube>
AddType application/x-httpd-php .php
[...]
And restart apache
service apache2 restart
Then edit the RoundCube config.inc.php configuration file:
nano /etc/roundcube/config.inc.php
and change the default host to localhost:
$config['default_host'] = 'localhost';
This prevents that Roundcube will show server name input field in the login form.
17. Install ISPConfig 3.1
To install ISPConfig 3 from the latest released version, do this:
cd /tmp
wget -O ispconfig.tar.gz
https://git.ispconfig.org/ispconfig/ispconfig3/repository/archive.tar.gz?ref=stable-3.1tar xfz ispconfig.tar.gz
cd ispconfig3*/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.
# php -q install.php
