我们在使用Red Hat系列与CentOS系列的Linux系统时经常要配置yum源，本文档提出一个快速配置yum源的方法，就是用shell脚本来实现。
首先确保系统已挂载好镜像文件，然后执行vim rhel7.repo.sh命令，这个命令是创建一个脚本。
在打开的文件中添加以下内
[root@linuxprobe ~]# vim rhel7.repo.sh 1 #!/bin/bash 2 3 cd /etc/yum.repos.d 4 5 cat >>rhel7.repo<<OK 6 [rhel7] 7 name=rhel7 8 baseurl=file:///media/cdrom 9 enabled=1 10 gpgcheck=0 11 OK 12 13 mkdir -p /media/cdrom 14 mount /dev/cdrom /media/cdrom 15 echo "/dev/cdrom /media/cdrom iso9660 defaults 0 0" >> /etc/fstab 16 17 yum clean all 18 yum makecache
写完脚本后记得赋予脚本执行权限：
[root@linuxprobe ~]# chmod 755 rhel7.repo.sh 或 [root@linuxprobe ~]# chmod +x rhel7.repo.sh
赋予脚本执行权限后再运行脚本：
[root@linuxprobe ~]# base rhel7.repo.sh 或 [root@linuxprobe ~]# ./rhel7.repo.sh
测试：
[root@linuxprobe ~]# yum instll httpd
Loaded plugins: fastestmirror, langpacks
No such command: instll. Please use /usr/bin/yum --help
[root@linuxprobe ~]# yum install httpd
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile

最后出现Complete!说明httpd安装成功，同时也说明了yum仓库配置成功！
注：我用的系统是RHEL/CentOS 7，用其他Linux系统的话只需要改yum仓库名称即可。
