Linux系统管理-yum源配置
一、本地光盘yum源配置1、创建挂载点
# mkdir /mnt/cdrom2、配置自动挂载本地光盘
# 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 03、配置yum源
#创建备份原有yum源文件的目录
# mkdir bak
#移动原有yum源文件到bak目录
# mv *.repo bak
#进入bak目录
# cd bak
#复制光盘yum源文件到/etc/yum.repos.d目录
# cp CentOS-Media.repo ..
#返回到/etc/yum.repos.d目录
# cd ..
#打开光盘yum源文件
# vim CentOS-Media.repo
# CentOS-Media.repo
……省略部分内容……
#yum --disablerepo=\* --enablerepo=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-64、清理并生成缓存
# yum clean all && yum makecache

1、备份系统原有的源配置文件
#进入yum源文件存放目录
# cd /etc/yum.repos.d/
#创建备份原yum源文件目录
# mkdir bak
#移动原yum源文件到备份目录
# mv *.repo bak2、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
