CentOS6国内常用yum源站点

1、腾讯云镜像站

https://mirrors.cloud.tencent.com/

1)替换之前先备份旧配置

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

2)wget下载仓库配置文件

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos6_base.repo

3)然后更新缓存

yum clean all

yum makecache

2、阿里云镜像站

https://opsx.alibaba.com/mirror

CentOS6为例

1)、备份

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

2)、下载新的CentOS-Base.repo 到/etc/yum.repos.d/

CentOS 6

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

或者

3)、之后运行yum makecache生成缓存

3、清华大学镜像站

CentOS 镜像使用帮助

首先备份 CentOS-Base.repo sudo mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

之后启用 TUNA 软件仓库，将以下内容写入 /etc/yum.repos.d/CentOS-Base.repo

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
