 yum install zabbix-agent
After this open:
 nano /etc/zabbix/zabbix_agentd.conf
And insert:
 Server=myzabbixserverdomain.com   # IP-address or DNS of your zabbix-server
 Hostname=Zabbix server            # Host name must be similar with Configuration -> Hosts in GUI
Add autostarting and start the agent:
 chkconfig zabbix-agent on
 service zabbix-agent start
Now you need to add this node in zabbix GUI. How to do this, you can see in official zabbix documentation:
