如果你不知道在哪里可以找到ifconfig命令，請按照以下簡單的步驟來找到它。首先，讓我們找出哪個包提供了ifconfig命令。要完成這項任務，輸入以下命令：
[root@jrserver app_files]# yum provides ifconfig Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.163.com * epel: mirrors.tuna.tsinghua.edu.cn * extras: mirrors.aliyun.com * updates: mirrors.163.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
就像你在上面的輸出中所看到的，net-tools包提供了ifconfig命令。因此，讓我們安裝net-tools包來使用ifconfig命令：
yum install net-tools
