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 Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.xmission.com * epel: mirror.hmc.edu * extras: centos.s.uw.edu * updates: mirrors.syringanetworks.net Resolving Dependencies --> Running transaction check ---> Package net-tools.x86_64 0:2.0-0.22.20131004git.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved =============================================================================================================================================================== Package Arch Version Repository Size =============================================================================================================================================================== Installing: net-tools x86_64 2.0-0.22.20131004git.el7 base 305 k Transaction Summary =============================================================================================================================================================== Install 1 Package Total download size: 305 k Installed size: 917 k Is this ok [y/d/N]: y Downloading packages: net-tools-2.0-0.22.20131004git.el7.x86_64.rpm | 305 kB 00:00:04 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : net-tools-2.0-0.22.20131004git.el7.x86_64 1/1 Verifying : net-tools-2.0-0.22.20131004git.el7.x86_64 1/1 Installed: net-tools.x86_64 0:2.0-0.22.20131004git.el7 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。
