一、本地光盘yum源配置
1、创建挂载点
[root@localhost ~]# mkdir /mnt/cdrom
2、配置自动挂载本地光盘
[root@localhost ~]# vim /etc/fstab
#
# /etc/fstab
# Created by anaconda on Sun Oct 20 16:02:54 2024
……省略部分内容……
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
#添加开机自动挂载系统光盘
/dev/cdrom /mnt/cdrom iso9660 defaults 0 0
3、配置yum源
#创建备份原有yum源文件的目录
[root@localhost yum.repos.d]# mkdir bak
#移动原有yum源文件到bak目录
[root@localhost yum.repos.d]# mv *.repo bak
#进入bak目录
[root@localhost yum.repos.d]# cd bak
#复制光盘yum源文件到/etc/yum.repos.d目录
[root@localhost bak]# cp CentOS-Media.repo ..
#返回到/etc/yum.repos.d目录
[root@localhost bak]# cd ..
#打开光盘yum源文件
[root@localhost yum.repos.d]# vim CentOS-Media.repo
# CentOS-Media.repo
……省略部分内容……
# yum --disablerepo=\* --enablerepo=c6-media [command]
[c6-media]
name=CentOS-$releasever - Media
baseurl=file:///mnt/cdrom/ #配置挂载点目录
# file:///media/cdrom/
# file:///media/cdrecorder/
gpgcheck=1
enabled=1 #开启。把默认值0修改为1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
4、清理并生成缓存
[root@localhost ~]# yum clean all && yum makecache
已加载插件：fastestmirror, security
Cleaning repos: c6-media
清理一切

c6-media/primary_db | 4.7 MB 00:00 ...
c6-media/other_db | 2.8 MB 00:00 ...
元数据缓存已建立
5.查看yum源
[root@localhost ~]# yum repolist

二、阿里云yum源配置
1、备份系统原有的源配置文件
#进入yum源文件存放目录
[root@localhost ~]# cd /etc/yum.repos.d/
#创建备份原yum源文件目录
[root@localhost yum.repos.d]# mkdir bak
#移动原yum源文件到备份目录
[root@localhost yum.repos.d]# mv *.repo bak
2、下载阿里云yum源配置文件
#CentOS6
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-6.10.repo
#CentOS7
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
#CentOS8
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
使用CentOS6为例演示
#下载CentOS6的阿里云yum配置文件
[root@localhost yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-6.10.repo
