In the process of building Zabbix Monitoring for the first time. Everything is going pretty good, but the Red Hat & CentOS Installation from Packages documentation for proxy configuration seems off. Below "Configure Database for Zabbix Proxy", it says to edit zabbix_proxy.conf. However, the code following that statement is a vi command to edit zabbix_server.conf. Also have found this to occur other than just Red Hat / CentOS. Probably am getting it right on my own, but taking considerable extra time to sort this out.
