用脚本配置yum源

首先把系统镜像挂载过来：

在右下角的光盘标志这里右键，然后点击连接，桌面就会出现镜像图标。

然后再执行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容：

#!/bin/bash

cd /etc/yum.repos.d

cat >>rhel7.repo<<OK
[rhel7]
name=rhel7
baseurl=file:///media/cdrom
enabled=1
gpgcheck=0
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：

chmod 755 rhel7.repo.sh或者chmod +x rhel7.repo.sh

赋予脚本执行权限后再运行脚本：

bash rhel7.repo.sh 或者./rhel7.repo.sh

测试：

[root@localhost Desktop]# yum install -y httpd

Complete!

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RedHat7，用其他Linux系统的话只需要改yum仓库名称即可。
