Next, we will see how to install the Zabbix server in a distributed way. This means that we will install all three components on different servers. In big setups, this can be a win as the frontend, Zabbix server, and database will have their own hardware.
For this setup to work, we need three machines, all with the latest version from Red Hat 6.x or CentOS 6.x with proper host name resolution, either by Domain Name System (DNS) or by host file. In this setup, I will talk about the setup of the server, db, and frontend. This time, we will disable SELinux on all machines as it is slightly more complicated and out of the scope of this book.
First thing to do is add on every host the Zabbix repository from Zabbix like we have done with our server installation. Remember the repository can be found in the Zabbix installation manual under installation from package.
On the DB server we install, of course, the MySQLserver:
# yum...
