Install Zabbix Agent 4.0.x¶

Preliminary note¶

also check back on zabbix-wiki http://www.zabbix.com/wiki/howto/monitor/os/linux/agentinstallonlinux (this is still for CentOS 5.x but may be of help)

Requirements¶

• EPEL

Agent-Install¶

yum update
yum --enablerepo=epel install zabbix40-agent

vim /etc/zabbix/zabbix_agentd.conf

# line 82: change to your Zabbix-server
Server=192.168.56.1

# line 105: change to your hostname
Hostname=application.server.example.com

vim /etc/zabbix/zabbix_agent.conf

# line 13: change to your Zabbix-server
Server=192.168.56.1

systemctl start zabbix-agent
systemctl enable zabbix-agent

Firewall¶

you have to open port 10050 tcp

firewall-cmd --permanent --add-port=10050/tcp --zone=public
firewall-cmd --reload

Troubleshoot¶

The agent failed to start ... see status
see also https://www.zabbix.com/forum/showthread.php?t=46796

tried to set PID to PIDFile=/tmp/zabbix_agentd.pid

vim /etc/zabbix/agentd.conf
vim /usr/lib/systemd/system/zabbix-agent.service

systemctl daemon-reload
systemctl start zabbix-agent

didn't work either.

double checked that /run/zabbix/ was existing and had right owner/rights
everything seemed to be ok.

After another restart and reset the PID back to PIDFile=/run/zabbix/zabbix-agentd.pid and another daemon-reload everything worked out ok.
