Note : I'm using zabbix server 1.8,for another version it should be same.

·         Add zabbix repository to linux host

rpm -Uvh http://repo.zabbix.com/zabbix/1.8/rhel/5/x86_64/zabbix-release-1.8-1.el5.noarch.rpm for Rhel5
rpm -Uvh http://repo.zabbix.com/zabbix/1.8/rhel/6/x86_64/zabbix-release-1.8-1.el6.noarch.rpm for Rhel6

·         Install zabbix agent

yum install zabbix zabbix-agent

·         Configure zabbix-agent.conf (Active check)

Edit file with nano /etc/zabbix/zabbix_agent.conf
Our zabbix server use active check configuration (server doesn’t request data,but agent),so set this :
Server=yourzabbixserverip
ServerActive=yourzabbixserverip

·         Start zabbix-agent service

/etc/init.d/zabbix-agent start

·         set zabbix-agent as startup

chkconfigzabbix-agent on

·        Make sure zabbix server are open port 10051 to agent’s ip,if not we need to allow it first by adding below rule to zabbix server’s iptables

-A INPUT -s agent-ip -p tcp -m state --state NEW -m tcp --dport 10051 -m comment --comment "linux-host" -j ACCEPT
·         New host need to be enabled via zabbix web interface.

It can be done via Configuration – host –Groups (Discovered hosts) – click status to activate it


Voila its done !
