Unlike simple mirroring or backup utilities, it updates both replicas of a distributed directory structure. When you want to activate a firewall on the master or slave server, ensure that you open port 3306 for MySQL, 22 for SSH and 4711 for Dovecot on both servers.Is a free, cross platform file synchronization tool that enables us to keep two set of file replicas (instances) on two different systems or on different disks of the same system.

You must use the same port ( 4711) and the same password ( replication_password) on both servers. If you have already mailвЂ™s on server1, they will be replicated to server2 without any further interaction. Since Dovecot 2 it`s possible to use DovectвЂ™s dsync to keep the main base in sync.

Install ISPConfig on the Master-Server according to The Perfect Server вЂ“ Debian 8.4 Jessie (Apache2, BIND, Dovecot, ISPConfig 3.1).ДЄdd the Slave Server to the /etc/hosts fileДЎ92.168.0.105 server1 If you have already installed ISPConfig on this Server, you can skip the installation ( ensure, that the existing installation is up-to-date). Mysql -u root -p 2 Install the Master ServerДЇirst we need to install ISPConfig on the Master-Server. If you need to make changes in MySQL login into MySQL with the root-password for MySQL: Wherever these hostnames or IP addresses occur in the next installation steps you will have to change them to match the IPвЂ™s and hostnames of your servers.ДЄll commands must be run as the root user. In my example I use the following hostnames and IP addresses for the two servers: To install the clustered setup, we need two servers with a Debian 8.4 minimal installВ and the same ISPConfig version.

In this setup, there will be one master server (which runs the ISPConfig control panel interface) and one slave server which mirrors the web (apache), email (postfix and dovecot), dns (bind) and database (MySQL or MariaDB) services of the master server. MySQL Master/Master replication will be used to replicate the MySQL client databases between the servers, Unison will be used to Sync the /var/www (websites) and the Mails will be synced with Dovecot. This tutorial describes the installation of a clustered web, email, database and DNS server to be used for redundancy, high availability and load balancing on Debian 8 with the ISPConfig 3 control panel.
