故障排除：CentOS 7 – 找不到netstat命令

最近，我在CentOS 7上进行一项工作，并想要验证它是否在监听端口80，使用netstat命令。

你猜怎么着？当我执行netstat时，我得到了下面的错误。

[root@instance-1 init.d]# netstat -anlp |grep 80
-bash: netstat: command not found
[root@instance-1 init.d]#

解决方法：-

使用yum命令安装net-tools

yum install net-tools

例如：

[root@instance-1 init.d]# yum install net-tools

Complete!
[root@instance-1 init.d]#

然后我就能够使用netstat了。

[root@instance-1 init.d]# netstat -anlp |grep 80
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      1818/nginx: master
[root@instance-1 init.d]#

我希望这能帮助你解决CentOS 7上的netstat未找到错误。
