如果你不知道在哪里可以找到ifconfig命令，请按照以下简单的步骤来找到它。首先，让我们找出哪个包提供了ifconfig命令。要完成这项任务，输入以下命令：
[root@jrserver app_files]# yum provides ifconfig
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors..com
* epel: mirrors.tuna.tsinghua.edu.cn
* extras: mirrors.aliyun.com
* updates: mirrors..com
net-tools-2.0-0.17.20131004git.el7.x86_64 : Basic networking tools
Repo : @base
Matched from:
Filename : /usr/sbin/ifconfig
或者你也可以使用以下命令：
yum whatprovides ifconfig
就像你在上面的输出中所看到的，net-tools包提供了ifconfig命令。因此，让我们安装net-tools包来使用ifconfig命令：
yum install net-tools
[root@jrserver app_files]# ifconfig
