Step #01: At first download rpm package from Zabbix official page.

Step #02: Configure iptables for allow Zabbix port. Open iptables file.

[[email protected] ~]#   vi /etc/sysconfig/iptables

Then insert below line into iptables file.

# Zabbix-Agent
-A RH-Firewall-1-INPUT -p tcp –dport 10050 -j ACCEPT

Now restart your iptable service via systemctl.

[[email protected] ~]#   systemctl restart iptables

Step #03: Now configure Zabbix agent. So at first enable Zabbix agent.

[[email protected] ~]#  systemctl enable zabbix-agent

Then start Zabbix service via command.

ServerActive=20.50.10.10
Hostname=XEN-SERVER

Server=Your Zabbix Server IP address

ServerActive=Your Zabbix Server IP address

Hostname=Your XEN Server Host Name

Then save and exit command below.

Troubleshooting : when you add new rule and can’t start iptables service 

Error : 

Job for iptables.service failed because the control process exited with error code. See “systemctl status iptables.service” and “journalctl –xe” for details.

when you add new rule and can’t start iptables service

Solution : First save iptables new rule

[[email protected]~]# /sbin/service iptables save

Second : iptable service start

[[email protected]~]# service iptables start

3rd : iptable service status

[[email protected]~]# service iptables status

Remember it! When you add new rule then first save and then start iptables service. But many people without save and restart iptables service.
