shell脚本快速配置yum源

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 
   #!/bin/bash

   cd /etc/yum.repos.d

   cat >>rhel7.repo<<OK
   [rhel7]
   name=rhel7
   baseurl=file:///media/cdrom
   enabled=
  gpgcheck=
  OK

  mkdir -p /media/cdrom
  mount /dev/cdrom /media/cdrom
  echo "/dev/cdrom /media/cdrom iso9660 defaults 0 0" >> /etc/fstab

  yum clean all
  yum makecache

写完脚本后记得赋予脚本执行权限：

[root@linuxprobe ~]# chmod  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。
