CentOS7 ifconfig Command not found

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: Command not found

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

[root@chaoge ~]# yum install net-tools

Nothing to do

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
