Create an ISPConfig3 Web Server in Linux


ISPConfig 3 is a Linux based hosting system to allow for multi host multi client systems on a single web server. This batch of commands to walk through means you can create this type of server very quickly and have a webserver in the cloud in under an hour. You can then add multiple websites across multiple clients. The end result is a console that looks like this….

To create the server, you need to either have one already in the cloud to use. Or maybe inside your company network, but if you don’t have one, either purchase one from Blue Host, or OVH. Links are below.


Once you have the server built and configured with console access, then follow this instructions to create the implementation.

yum -y install net-tools nano
systemctl stop firewalld.service
systemctl disable firewalld.service
nano /etc/hostname

Update the hostname with the FQDN for your external facing internet presence.

nano /etc/selinux/config

Add the line


The Reboot the server. The run the following code

rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*
yum -y install epel-release
yum -y update
yum -y groupinstall 'Development Tools'

yum install

yum-config-manager --enable remi-php72
yum -y install ntp httpd mod_ssl mariadb-server php php-mysql php-mbstring phpmyadmin
echo "RequestHeader unset Proxy early" >> /etc/httpd/conf/httpd.conf
service httpd restart
yum -y install dovecot dovecot-mysql dovecot-pigeonhole
touch /etc/dovecot/dovecot-sql.conf
ln -s /etc/dovecot/dovecot-sql.conf /etc/dovecot-sql.conf
ln -s /etc/dovecot/dovecot.conf /etc/dovecot.conf
systemctl enable dovecot
systemctl start dovecot
yum -y install postfix
systemctl enable mariadb.service
systemctl start mariadb.service
systemctl stop sendmail.service
systemctl disable sendmail.service
systemctl enable postfix.service
systemctl restart postfix.service
yum -y install getmail

Perform the MySQL installation with this line.

nano /etc/httpd/conf.d/phpMyAdmin.conf

Enter the following block in the the phpMyAdmin.conf file. There are 5 lines that need commenting out with the #.

<Directory /usr/share/phpMyAdmin/>
   <IfModule mod_authz_core.c>
     # Apache 2.4
  #  <RequireAny>
     #  Require ip
     #  Require ip ::1

     # Apache 2.2
     Order Deny,Allow
     Deny from All

nano /etc/phpMyAdmin/

Edit this file and place in the following items.

/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'http';

Then run the following lines.

Run this command

nano /etc/php.ini

And add the line – CGI.FIX_PATHINFO=1 as below

;error_reporting = E_ALL & ~E_DEPRECATED
error_reporting = E_ALL & ~E_NOTICE & ~E_DEPRECATED & ~E_STRICT
; cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for CGI.  PHP's
; previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and to not grok
; what PATH_INFO is.  For more information on PAppp.tldTH_INFO, see the cgi specs.  Setting
; this to 1 will cause PHP CGI to fix its paths to conform to the spec.  A setting
; of zero causes PHP to behave as before.  Default is 1.  You should fix your scripts

yum install openssl
nano /etc/pure-ftpd/pure-ftpd.conf

Inside the pure-ftpd.conf file add the TLS line

# This option can accept three values :
# 0 : disable SSL/TLS encryption layer (default).
# 1 : accept both traditional and encrypted sessions.
# 2 : refuse connections that don't use SSL/TLS security mechanisms,
#     including anonymous sessions.
# Do _not_ uncomment this blindly. Be sure that :
# 1) Your server has been compiled with SSL/TLS support (--with-tls),
# 2) A valid certificate is in place,
# 3) Only compatible clients will log in.
