3. CentOS 7 zabbix-agent root 실행

## zabbix_agentd.conf 에 AllowRoot 옵션이 있으나 옵션 설정을 하고 데몬 시작을 하여도 zabbix user로 실행 되는 경우가 있음.
[root@ZABBIX-AGENT zabbix]# cat zabbix_agentd.conf | grep AllowRoot=
AllowRoot=1
 
 
## zabbix user로 zabbix-agent가 실행됨
[root@ZABBIX-AGENT zabbix]# ps aux | grep zabbix

## 이경우 systemd service 설정에서 user와 group을 지정해 준다.
[root@ZABBIX-AGENT zabbix]# cat /usr/lib/systemd/system/zabbix-agent.service
...
 
[Service]

User=root
Group=root
...
 
 
## daemon reload
[root@ZABBIX-AGENT zabbix]# systemctl daemon-reload
 
 
## zabbix-agent 재시작후 확인
[root@ZABBIX-AGENT zabbix]# systemctl restart zabbix-agent
[root@ZABBIX-AGENT zabbix]# ps aux | grep zabbix
