After Zabbix Agent has been successfully installed, we need to add the IP of the Zabbix monitoring server in the Zabbix Agent configuration file /etc/zabbix/zabbix_agentd.conf

[root@webserver02 ~]# vi /etc/zabbix/zabbix_agentd.conf

 

### Option: Server
#       List of comma delimited IP addresses (or hostnames) of Zabbix servers.
#       Incoming connections will be accepted only from the hosts listed here.
#       If IPv6 support is enabled then '127.0.0.1', '::127.0.0.1', '::ffff:127.0.0.1' are treated equally.
#
# Mandatory: no
# Default:
# Server=
Server=192.168.1.201 # Add here the IP of your Zabbix Server
#
### Option: ServerActive
# ServerActive=
#
ServerActive=192.168.1.201 # Add here the IP of your Zabbix Server

 

Step 4 – Enable/Start Zabbix Agent

[root@webserver02 ~]# Systemctl enable zabbix-agent
[root@webserver02 ~]# Systemctl start zabbix-agent
