最近安装了一个最小化版本的CentOS 7，发现不能使用 ifconfig命令，界面提示：
shellifconfig command not found.
解决办法
从yum找出哪个包括ifconfig 命令
[root@tangym ~]# yum provides ifconfig Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
base: mirrors.zju.edu.cn
extras: mirrors.163.com
updates: mirrors.163.com
net-tools-2.0-0.22.20131004git.el7.x86_64 : Basic networking tools
Repo : @base
Matched from:
Filename : /usr/sbin/ifconfig
从上面可以看到 net-tools 包中可以找到ifconfig命令 安装net-tools
[root@tangym ~]# yum provides ifconfig
安装完成之后，将可以使用ifconfig 命令了
[root@tangym ~]# ifconfig
