#脚本给与 执行权限

[root@zabbix-agent2 ~]# chmod +x  /etc/zabbix/script/discovery.sh

使用netstat命令输出端口号；-tnlp=Tcp协议+不显示别名+listen状态+显示程序名称；$1~$9表示输出的第几个参数；awk {'print $4'}表示输出第4个参数（如0.0.0.0:80）；awk -F':' '{if ($NF~/^[0-9]*$/) print $NF}表示截取冒号后面的值，且只能是0~9的数字；|sort|uniq表示排序和去重。

脚本中注释掉的两行是用来监控服务的，只需替换掉其上的一行就是个扫描服务的脚本了。
