How to install ISPConfig 3 on CentOS 7

How to Install ISPConfig 3 on CentOS 7

In this article, we will show you how to install ISPConfig 3 on a CentOS 7 VPS, as well as go through the initial configuration.

ISPConfig is an open-source hosting control panel for Linux which has a user-friendly web interface – with it, users can manage their websites, email addresses, FTP accounts, DNS records, databases, and shell accounts.

How to Install ISPConfig 3 on a CentOS 7 VPSThe ISPConfig has four different levels of user access, which are as follows: Administrator, Reseller, Client, and Email-user. Each of these has varying levels of access to ISPConfig’s menus.


  • A Server running CentOS 7
  • Access to the root user, or access to a user with sudo privileges.

Step 1: Connect to your server

Before we begin, you need to connect to your server via SSH as the root user, or as a user with sudo privileges. To do this, use the following command:

ssh root@IP_address -p Port_number

Of course, you will need to replace IP_address and Port_number with your actual server IP address and SSH port number.

Once you are logged in to the server, you can type the following commands to update all of your currently installed packages to their latest available versions. After that, you’ll enable the required packages for the ISPConfig by installing the “Development Tools” bundle:

yum install yum-priorities
yum update
yum groupinstall 'Development Tools'

Enable the EPEL repository if it is not already done so:

yum install epel-release

Install the following packages:

yum install NetworkManager-tui awstats bzip2 getmail quota mailman nano net-tools openssl perl-DateTime-Format-Builder perl-DateTime-Format-HTTP postgrey re2c rkhunter unzip yum-utils webalizer wget
rpm -Uvh

Restart the server for the changes to take effect.

Step 2: Install LAMP Stack

Once the system is up to date, we can continue installing the LAMP stack with Apache, MariaDB, PHP, NTP, and phpMyAdmin:

cd opt/
rpm -Uvh remi-release-7.rpm
yum-config-manager --enable remi-php72
yum install ntp httpd mod_ssl mariadb-server php php-mysql php-mbstring phpmyadmin

In order to log in to phpMyAdmin from any IP address, edit the phpMyAdmin configuration file (/etc/httpd/conf.d/phpMyAdmin.conf) and remove the following lines:

Require ip
Require ip ::1

Also, edit the /etc/phpMyAdmin/ file and change the authentication, i.e replace:

$cfg['Servers'][$i]['auth_type'] = 'cookie';


$cfg['Servers'][$i]['auth_type'] = 'http';

Edit the /etc/httpd/conf.d/awstats.conf Awstats configuration file and replace ‘Require local’ to ‘Require all granted’.
Restart the Apache service for the changes to take effect:

service httpd restart

After the LAMP stack has been successfully installed on your server, you can use the commands below to start and enable the MariaDB service on the server.

systemctl start mariadb.service
systemctl enable mariadb.service

The next command is optional but recommended by us. You can run this command if you want to secure your MariaDB server by disallowing remote root access, removing the test database, and creating a root password.


When prompted, answer the questions below by following the guide.

Enter current password for root (enter for none): Press the [Enter] key - we do not have a password currently set.
Set root password? [Y/n]: Y
New password: Enter your password
Re-enter new password: Repeat your password
Remove anonymous users? [Y/n]: Y
Disallow root login remotely? [Y/n]: Y
Remove test database and access to it? [Y/n]: Y
Reload privilege tables now? [Y/n]: Y

Restart the MariaDB server so that the changes take effect.

Step 3: Install Dovecot

You can execute the following command to install Dovecot on your server:

yum -y install dovecot dovecot-mysql dovecot-pigeonhole

When the installation is complete, create a dovecot-sql.conf file using the command below, after which you’ll make a symbolic link pointing back to the file you just created:

touch /etc/dovecot/dovecot-sql.conf
ln -s /etc/dovecot/dovecot-sql.conf /etc/dovecot-sql.conf

Now use the following commands to restart and enable the Dovecot service on the server.

systemctl restart dovecot.service
systemctl enable dovecot.service

Step 4: Install Amavisd-new, ClamAV, and SpamAssassin

By using the next command you will install ClamAV, Amavisd, and SpamAssassin, along with all of these additionally required packages, all in one go.

yum -y install amavisd-new spamassassin clamav clamd clamav-data clamav-devel clamav-update perl-DBD-mysql

Step 5: Install PHP and Apache2 Modules

In this step, we will install some required Apache and PHP modules, such as mod_php, mod_fcgid, php-mysql, and so on. To proceed with the installation of the modules, use the command below:

yum -y install php-ldap php-mysql php-odbc php-pear php php-devel php-gd php-imap php-xml php-xmlrpc php-pecl-apc php-mbstring php-mcrypt php-mssql php-snmp php-soap php-tidy curl curl-devel mod_fcgid php-cli httpd-devel php-fpm perl-libwww-perl ImageMagick libxml2 libxml2-devel python-devel

Step 6: Install PureFTPd

The most popular method for transferring files from one server to another or from one place to other is through the FTP protocol. In order to use this protocol, you’ll need to install an FTP server first. We will install PureFTP server because it is simple to install and easy-to-use. To install it on your server you only need to execute the following command:

yum -y install pure-ftpd

Step 7: Install BIND

BIND, or named, is one of the most commonly used Domain Name System software packages available on the Internet. In order for ISPConfig to be able to manage and configure the DNS settings, you need to install the following packages on the server:

yum -y install bind bind-utils

Edit the /etc/named.conf file, remove all the lines and add the following lines:

options {
        listen-on port 53 { any; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        allow-query     { any; };
				allow-recursion {"none";};
        recursion no;
logging {
        channel default_debug {
                file "data/";
                severity dynamic;
zone "." IN {
        type hint;
        file "";
include "/etc/named.conf.local";

Create a new ‘named.conf.local’ file in the /etc directory on your server:

touch /etc/named.conf.local

Restart the named service for the changes to take effect:

service named restart

Step 8: Install Let’s encrypt

We can easily add support for Let’s Encrypt in Apache using:

yum -y install certbot-apache

Add a cronjob so the Let’s Encrypt SSL certificates can be renewed automatically:

* 4 * * * /usr/bin/certbot renew >/dev/null 2>&1

Step 9: Install fail2ban

Stop and disable the firewalld service:

systemctl stop firewalld.service
systemctl disable firewalld.service

Then, install fail2ban:

yum install iptables-services fail2ban fail2ban-systemd

Step 10: Install ISPConfig

After we finish all previous steps, it’s time to download and install ISPConfing 3 on the server. We will use the wget command to make a copy of the official web link on the ISPConfig website. To change the directory to /opt/ and download the ISPConfig packages, run the next two commands:

cd /opt/

Once the package has been downloaded, we’ll need to unpack it in order to use it. Unpack it with the command:

tar -zxvf ISPConfig-3-stable.tar.gz

Then use the following command to change the directory where the install script is placed.

cd ispconfig3_install/install/

To start the installation, you need to run this command:

    PHP Warning: date(): It is not safe to rely on the system’s timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone _set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected t he timezone ‘UTC’ for now, but please set date.timezone to select your timezone. in /opt/ispconfig3_install/install/install.php on line 628
    Installation completed.

    • You should be able to fix this warning by defining a default timezone in your php.ini file.

      As an example, you can do this by adding the following line:

      date.timezone = America/New_York

      Don’t forget to restart your Apache web server after this change.

    • If you want to allow access only from specific IPs, you can simply add them to the configuration. For example if you want to allow access only from IP ( you can set the following in /etc/httpd/conf.d/phpMyAdmin.conf:

      Require ip
      Require ip
      Require ip ::1

  2. I follow all steps when I execute the command php -q install.php, ispconfig configuration didn’t complete :
    > Initial configuration
    Operating System: CentOS 7.9
    sh: which: command not found
    ISPConfig requires which

  3. Installation completed. But still cannot access to http://myip:8080. And yes, the port is open. I also tried with another open port (8000), still don’t work. Help please.
