Linux下安装ifconfig命令（Centos找不到ifconfig命令）

很多时候，最下化安装Linux ，会发现很多基础的命令都没有 。

这个时候，只能自己安装了 。

比如，

想查看刚安装的Linux服务器 ，IP地址是多少 。

很多同学，会用ifconfig 查看 。

如果找不到此命令 ，怎么安装呢 ？

直接用 yum install ifconfig  吗 ？

会发现，并不是 。

怎么找到是啥命令呢 ？

试试命令

yum whatprovides ifconfig

[root@idoxu-istester ~]# yum whatprovides ifconfig

你会发现，原来在net-tools下 。

执行命令 yum install net-tools 搞定 。

[root@idoxu-istester ~]# yum install net-tools
