How To Deploy ISPConfig 3 on an Ubuntu 18.04 Server


ISPConfig is an open source web hosting control panel let's you configure the following services through its browser based interface:


  • Manage multiple servers from one control panel
  • Web server management (Apache2 and nginx)
  • Mail server management (with virtual mail users)
  • DNS server management (BIND and MyDNS)
  • Virtualization (OpenVZ)
  • Administrator, reseller and client login
  • Configuration mirroring and clusters
  • Open Source software (BSD license)
In this tutorial, we'll walk you through the steps to install and configure ispconfig 3.1 on an Ubuntu 18.04 server. You will need to replace some of the highlighted information while performing these steps to meet your environment needs.

Prerequisites
To follow this tutorial, you will need one Ubuntu 18.04 server installed either on a (Physical or Virtual) machine with a non-root user having sudo privileges.

Setting Timezone and Hostname

sudo timedatectl set-timezone Asia/Karachi
sudo hostnamectl set-hostname labserver.layloyar.com

Set Up Default Shell

sudo dpkg-reconfigure dash


Uninstall Apparmor

sudo service apparmor stop

sudo apt autoremove apparmor apparmor-utils

Installing Postfix and Database
sudo apt -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

During installation postfix will present you following screen, choose Internet Site and press OK


Enter you FQDN on this screen and press OK


Edit master.cf file and add or replace the following contents:

sudo nano /etc/postfix/master.cf

Change this:

#submission inet n       -       y       -       -       smtpd
#  -o syslog_name=postfix/submission
#  -o smtpd_tls_security_level=encrypt
#  -o smtpd_sasl_auth_enable=yes

#  -o smtpd_recipient_restrictions=
#  -o smtpd_relay_restrictions=permit_sasl_authenticated,reject
#  -o milter_macro_daemon_name=ORIGINATING

to this:

#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=$mua_client_restrictions
#  -o smtpd_helo_restrictions=$mua_helo_restrictions
#  -o smtpd_sender_restrictions=$mua_sender_restrictions
#  -o smtpd_recipient_restrictions=
#  -o smtpd_relay_restrictions=permit_sasl_authenticated,reject
#  -o milter_macro_daemon_name=ORIGINATING

#  -o smtpd_recipient_restrictions=
#  -o smtpd_relay_restrictions=permit_sasl_authenticated,reject
#  -o milter_macro_daemon_name=ORIGINATING



Save and close.

This will look smiliar to like below.


Now restart postfix service to take changes into effect  

sudo systemctl restart postfix

Output:

Now edit 50-server.cnf file and replace the following

sudo nano /etc/mysql/mariadb.conf.d/50-server.cnf

Change this:

bind-address           = 127.0.0.1

to this:

#bind-address           = 127.0.0.1

Save and close.

Securing MySQL

sudo mysql_secure_installation

Output:
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

You already have a root password set, so you can safely answer 'n'.

Change the root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

Login to mysql prompt and execute the following.

sudo mysql -u root -p

Edit debian.cnf file and update the following.

socket   = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host     = localhost
user     = root
password =
socket   = /var/run/mysqld/mysqld.sock
basedir  = /usr

to this:

# Automatically generated for Debian scripts. DO NOT TOUCH!
[client]
host     = localhost
user     = root
password = TypePasswordHere
socket   = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host     = localhost
user     = root
password = TypePasswordHere
socket   = /var/run/mysqld/mysqld.sock
basedir  = /usr

Save and close.

This will look smiliar to like below.
