当服务器未安装 netstat 工具时，查看端口监听状态会提示如下报错 “command not found”。
[root@VM_0_15_linux ~]# netstat -an|grep 9200
-bash: netstat: command not found
如果要使用 netstat 命令，需要先安装工具，安装步骤如下所示。
一、首先配置好本机的 yum 源
[root@VM_0_15_linux ~]# yum repolist all
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
repo id repo name status
base/1.1/x86_64 UPEL-1.1 – Base enabled: 7,695
!extras/1.1/x86_64 UPEL-1.1 – Extras disabled
updates/1.1/x86_64 UPEL-1.1 – Updates enabled: 208
upel-media UPEL-1.1 – Media disabled
repolist: 7,903
二、查看提供命令的工具包
执行如下命令 yum provides */netstat 可以看到提供命令的工具包：
net-tools-2.0-0.22.20131004git.el7.x86_64。
[root@VM_0_15_linux ~]# yum provides */netstat
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
updates/1.1/x86_64/filelists_db | 1.1 MB 00:00:00

Matched from:
Filename : /bin/netstat
三、安装工具包
执行 yum install net-tools 安装命令。
[root@VM_0_15_linux ~]# yum install net-tools
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile

四、验证测试
利用本地监听的端口 9200 验证工具安装是否正常。
可以正常使用命令，说明安装正常。
[root@VM_0_15_linux ~]# netstat -an|grep 9200
tcp6 0 0 :::9200 :::* LISTEN
