I'm not sure what you (or your tutor) tries to accomplish but first things first. I guess your tutor is not knowing what he is talking about or you didn't explain it in such a way he really meant it. Anyway, you can NOT have more than 1 Zabbix Server running at the same time. Zabbix Server is not able to do so called 'High Availability'.

That said, Zabbix runs on a DB backend like MySQL. And yes you could setup a master/slave MySQL setup over multiple CentOS nodes and let Zabbix put his data into that DB.

Keep in mind, the Proxy method is not meant for failover. The Zabbix proxy is meant for monitoring hosts that are located in other networks and/or vlans.

My suggestion to you would be this:

- run 1 Zabbix Server instance
- run (at least) 2 MySQL instances with master/slave replication enabled
- run (at least) 2 Zabbix Web Front-Ends
- run 1 Load Balancer pointed to the 2 Zabbix Web Front-Ends
- run 1 Zabbix Proxy and keep in mind that the Zabbix Proxy needs his own database (you could of course put the database in the same MySQL master/slave setup)
- run (at least) multiple hosts with Zabbix Agent installed on it and put them in your Zabbix Proxy

If you need help, just ask :-)
