本文来为各位介绍一下CentOS7执行ifconfig Command not found 未找到命令错误问题的解决办法，希望能帮助到大家。
CentOS7刚发布，我忍不住把DELL T410从CentOS6升级到CentOS7。好不容易等安装结束后，立即配置网络，然后在yum源上安装环境。可是执行ifconfig的时候系统提示让我傻了眼：
[root@chaoge ~]# ifconfig
-bash: ifconfig: 未找到命令
这可是新安装的系统，怎么会没找到熟悉ifconfig命令呢？网上搜一下，一大堆人都在说是环境变量问题，但我确信我的/etc/profile设置是对的，于是终于找到一篇文章说是安装下net-tools就好
| 代码如下 |
|
| [root@chaoge ~]# yum install net-tools |
已加载插件：fastestmirror
| 代码如下 |

软件包 net-tools-2.0-0.17.20131004git.el7.x86_64 已安装并且是最新版本
无须任何处理
因为我已安装过net-tools所以提示我已经安装，现在熟悉的ifconfig又回来了
