How To Set Up a Complete Web Hosting Server on an Ubuntu 16.04

Update Source List

You need to 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:

nano /etc/apt/sources.list

It should look like this when changes done:

# deb-src http://security.ubuntu.com/ubuntu xenial-security multiverse

Now, you need to run the following:

apt-get update
apt-get upgrade

If you see that a new kernel gets installed as part of the updates, you should reboot the system afterwards:

reboot

Change the Default Shell

By default in Ubuntu 16.04 /bin/sh is a symlink to /bin/dash, however we need /bin/bash, not /bin/dash. Therefore, we do this:

dpkg-reconfigure dash

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

Disable AppArmor

AppArmor is a security extension (similar to SELinux) that should provide extended security. You must disable it if you want to install ISPConfig.

service apparmor stop
update-rc.d -f apparmor remove 
apt-get remove apparmor apparmor-utils

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.

apt-get -y install ntp ntpdate

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.

This 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 dovecot-lmtpd sudo

You will be asked the following questions:

General type of mail configuration: example.com
System mail name: labsrv.example.com

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       -       -       -       -       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
[...]

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

Then we restart MariaDB:

service mysql restart

Now check that networking is enabled. Run

netstat -tap | grep mysql

The output should look like this:
tcp6 0 0 [::]:mysql [::]:* LISTEN 5230/mysqld

Install Amavisd-new, SpamAssassin, and Clamav

To install amavisd-new, SpamAssassin, and ClamAV, run the following:

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 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

Edit the clamd configuration file:

nano /etc/clamav/clamd.conf

and change the line:

AllowSupplementaryGroups false

to:

AllowSupplementaryGroups true 

And save the file. To start ClamAV use:

freshclam
service clamav-daemon start

The following warning can be ignored on the first run of freshclam as we start the ClamAV daemn after we updated the database.

WARNING: Clamd was NOT notified: Can't connect to clamd through /var/run/clamav/clamd.ctl: No such file or directory

Install Metronome XMPP Server

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 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.

Install Apache, PHP, phpMyAdmin, FCGI, SuExec, Pear, and mcrypt

To install these packages, run the following:

apt-get install apache2 apache2-doc apache2-utils libapache2-mod-php php7.0 php7.0-common php7.0-gd php7.0-mysql php7.0-imap phpmyadmin php7.0-cli php7.0-cgi libapache2-mod-fcgid apache2-suexec-pristine php-pear php-auth php7.0-mcrypt mcrypt  imagemagick libruby libapache2-mod-python php7.0-curl php7.0-intl php7.0-pspell php7.0-recode php7.0-sqlite3 php7.0-tidy php7.0-xmlrpc php7.0-xsl memcached php-memcache php-imagick php-gettext php7.0-zip php7.0-mbstring

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 can not be attacked trough the HTTPOXY vulnerability, I will disable the HTTP_PROXY header in apache globally.

sudo nano /etc/apache2/conf-available/httpoxy.conf

Paste this content to the file:

RequestHeader unset Proxy early

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 web sites 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

PHP Opcode cache

APCu is a free PHP opcode cacher for caching and optimizing PHP intermediate code. It is strongly recommended to have one of these installed to speed up your PHP page.

APCu can be installed as follows:

apt-get install php7.0-opcache php-apcu

Now restart Apache:

service apache2 restart

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 php7.0-fpm

Make sure you enable the module and restart Apache:

a2enmod actions fastcgi alias 
service apache2 restart

Install HHVM (HipHop Virtual Machine)

In this step we will install HHVM with apt. HHVM is a fast PHP engine developed by Facebook.

apt-get -y install software-properties-common
apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0x5a16e7281be7a449
add-apt-repository "deb http://dl.hhvm.com/ubuntu xenial main"
apt-get update
apt-get -y install hhvm

Install Let's Encrypt

ISPConfig 3.1  has builtin 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 letsencrypt

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 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

Enter the email of the person running the list: admin@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

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"

Now run following:

newaliases

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:///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:

service apache2 restart

Then start the Mailman daemon:

service mailman start

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

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]:US
State or Province Name (full name) [Some-State]:Boston
Locality Name (eg, city) []:Boston
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Example
Organizational Unit Name (eg, section) []:IT
Common Name (eg, YOUR name) []:labsrv.example.com
Email Address []:admin@example.com

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).
#
#
/dev/mapper/labsrv--vg-root / ext4 errors=remount-ro,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 0 1


To enable quota, run these commands:

mount -o remount /

quotacheck -avugm

Which will show the following output:

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 11642 directories and 81307 files
quotacheck: Old file not found.
quotacheck: Old file not found.

Now run the following command

quotaon -avug

Output of above command
---
/dev/mapper/labsrv--vg-root [/]: group quotas turned on
/dev/mapper/labsrv--vg-root [/]: user quotas turned on

Install BIND DNS Server

BIND can be installed as follows:

apt-get install bind9 dnsutils haveged

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

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

Install Jailkit

Jailkit is needed only if you want to chroot SSH users. It can be installed as follows:

apt-get install build-essential autoconf automake1.11 libtool flex bison debhelper binutils

cd /tmp

wget http://olivier.sessink.nl/jailkit/jailkit-2.19.tar.gz

tar xvfz jailkit-2.19.tar.gz

cd jailkit-2.19

./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*

Install fail2ban and UFW

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:

nano /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

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

Then create the following two filter files:

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

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

nano /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\S*),.*
ignoreregex =

Add the missing ignoreregex line in the postfix-sasl file:

echo "ignoreregex =">> /etc/fail2ban/filter.d/postfix-sasl.conf

Restart fail2ban afterwards:

service fail2ban restart

To install the UFW firewall, run this apt command:

apt-get install ufw

Install Roundcube Webmail

To install Roundcube Webmail, run:

apt-get install roundcube roundcube-core roundcube-mysql roundcube-plugins roundcube-plugins-extra 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 first 2 alias lines, add the two other "Alias" statements and add the line "AddType application/x-httpd-php .php" right after the "" 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
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.

Install ISPConfig 3

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-3.1
tar 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.
