CentOS iso本地源配置

1.查看centos版本，下载对应iso文件

[root@data-service media]# cat /etc/issue
CentOS release 6.6 (Final)
Kernel \r on an \m

2.把iso文件传到服务器,可使用ftp工具,服务器之间传可用scp命令
3.挂载iso文件

#mkdir /media/centos-6.6 如果文件夹不存在则创建一个
 mount -o loop CentOS-6.6-x86_64-bin-DVD1.iso /media/centos-6.6/

开机自动挂载需要单独配置
4.编辑repo文件
首先把原来存在的repo文件移除备份

mkdir /etc/yum.repo.d/bk
mv /etc/yum.repo.d/*.repo /etc/yum.repo.d/bk

编写自己的repo文件
vim /etc/yum.repo.d/local.repo
内容如下

[c6-media]
name=CentOS-$releasever - Media

baseurl=file:///media/centos-6.6
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

enable表示是否启用，baseurl为路径

5.更新缓存

yum clean all
yum makecache
