CentOS 挂载iso文件配置yum源

1.挂载iso

准备好centos的光盘镜像

挂载前的准备;

mkdir -p /dev/centos

mkdir -p  /mnt/local_yum

挂载

mount -o loop /opt/software/CentOS-6.5-x86_64-bin-DVD1.iso /dev/centos/

拷贝文件

cp -r /dev/centos/* /mnt/local_yum/(大概4.2g,等待即可)

进入/mnt/local_yum/查看

2.配置yum文件

cd /etc/yum.repos.d/

(建议先对该目录下的repo文件进行备份)

cp CentOS-Media.repo local_yum.repo

vi  local_yum.repo,把baseurl换成我们上面拷贝文件的/mnt/local_yum,enabled设置为1

更改好了之后

yum clean all

yum makecache(可省)

yum repolist all

卸载镜像umount /dev/centos
