故障排除（netstat: command not found）

最近, 我在CentOS 7上安装了Nginx Plus, 想验证它是否使用netstat在端口80上侦听。
【故障排除（netstat: command not found）】你猜怎么着？执行netstat时出现以下错误。

[[email protected] init.d]# netstat -anlp |grep 80-bash: netstat: command not found[[email protected] init.d]#

解：-
使用yum命令安装net-tools

yum install net-tools

例如：

[[email protected] init.d]# yum install net-toolsLoaded plugins: fastestmirrorLoading mirror speeds from cached hostfile * base: mirrors.xmission.com * epel: mirror.hmc.edu * extras: centos.s.uw.edu * updates: mirrors.syringanetworks.netResolving Dependencies--> Running transaction check---> Package net-tools.x86_64 0:2.0-0.22.20131004git.el7 will be installed--> Finished Dependency ResolutionDependencies Resolved=============================================================================================================================================================== Package Arch Version Repository Size===============================================================================================================================================================Installing: net-tools x86_64 2.0-0.22.20131004git.el7 base 305 kTransaction Summary===============================================================================================================================================================Install 1 PackageTotal download size: 305 kInstalled size: 917 kIs this ok [y/d/N]: yDownloading packages:net-tools-2.0-0.22.20131004git.el7.x86_64.rpm | 305 kB 00:00:04 Running transaction checkRunning transaction testTransaction test succeededRunning 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![[email protected] init.d]#

然后我可以使用netstat。
