Linux系统优化yum源

Linux系统优化yum源

一、推荐的yum源:

  1. 阿里yum源:https://developer.aliyun.com/mirror/centos
  2. 清华yum源:https://mirrors.tuna.tsinghua.edu.cn/help/centos/
  3. 网易yum源:http://mirrors.163.com/.help/centos.html

二、以阿里yum源为例进行设置(系统Centos7)

2.1 配置基础的yum源

第一步:备份原有的 CentOS-Base.repo 文件

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

第二步:下载阿里提供的 CentOS-Base.repo 文件到 /etc/yum.repos.d/ 目录下

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

2.2 配置扩展的yum源

https://developer.aliyun.com/mirror/epel

第一步:备份(如果配置过其他epel源)

mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.backup
mv /etc/yum.repos.d/epel-testing.repo /etc/yum.repos.d/epel-testing.repo.backup

第二步:下载阿里提供的epel yun源文件到 /etc/yum.repos.d/ 目录下

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

没有wget命令的需要安装 yum install -y wget

2.3 重建yum缓存

yum clean all
yum makecache

三、代码复制

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
yum install -y wget
mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.backup
mv /etc/yum.repos.d/epel-testing.repo /etc/yum.repos.d/epel-testing.repo.backup
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum clean all
yum makecache
