esac

以上的两个文件，添加后，需要修改权限，

chown zabbix:zabbix -R /usr/local/zabbix

chmod 755 /usr/local/zabbix/etc/zabbix_agentd.conf.d/zabbix_tcp_conn_status.sh

zabbix agent启动

/usr/local/zabbix/sbin/zabbix_agentd

检查进程
1. 查看日志 tail -20 /usr/local/zabbix/zabbix_agentd.log
2. 查看进程 ps aux |grep zabbix
3. 查看端口 netstat -lpntu |grep zabbix
