I used scripts to install ZABBIX. After the successful installation, I found that there was no ZABBIX process. And there is no ZABBIX process file. So I need to create file ,such as
(1)mkdir -p /var/run/zabbix/
(2)chown zabbix.zabbix /var/run/zabbix/
(3)systemctl restart zabbix-agent
After that ,zabbix is OK
