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 https://static.lty.fun/%E5%85%B6%E4%BB%96%E8%B5%84%E6%BA%90/SourcesList/Centos-6-Vault-Aliyun.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 的源

wget -O /etc/yum.repos.d/CentOS-Base.repo https://www.xmpan.com/Centos-6-Vault-Aliyun.repo

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.
#

更新软件包缓存

yum makecache

4、EPEL镜像源

[root@localhost ~]#
yum -y install epel-release

# set [priority=5]
sed -i -e “s/]$/]npriority=5/g” /etc/yum.repos.d/epel.repo

# for another way, change to [enabled=0] and use it only when needed
[root@localhost ~]#
sed -i -e “s/enabled=1/enabled=0/g” /etc/yum.repos.d/epel.repo
# if [enabled=0], input a command to use the repository
[root@localhost ~]# yum –enablerepo=epel install [Package]
