centos安装ifconfig

前言

自从用来云服务器，虚拟机已经很久没碰了，近期想学习搭建邮件服务器，无奈云服务器商家都禁用了25端口，于是笔者想通过虚拟机的形式来搭建邮件服务器，所以安装了一台centos7，用过虚拟机的同学应该清楚在虚拟机了直接操作命令实在是不方便，那就通过xshell来连接吧，但当笔者输入ifconfig来查看ip是却发现命令未找到，这是咋回事呢，下面我们就来看看如何解决这个问题。

[root@192 /]# ifconfig
-bash: ifconfig: 未找到命令

1 用search命令查看一下ifconfig在哪个包里

[root@192 /]# yum search ifconfig
已加载插件：fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirror.jdcloud.com
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com
================================ 匹配：ifconfig =========================================
net-tools.x86_64 : Basic networking tools

2 yum安装依赖包net-tools.x86_64

[root@192 /]# yum install -y net-tools.x86_64
已加载插件：fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirror.jdcloud.com
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com

3 测试是否正确安装ifconfig

[root@192 /]# ifconfig
