Centos

提供CentOs 7与8，架构仅为x86_64。
建议先备份/etc/yum.repos.d/内的文件。
然后编辑/etc/yum.repos.d/中的响应文件，在mirrorlist=开头行前面加#注释掉；并将baseurl=开头行取消注释。
对于CentOS 7，请把改行内的域名（例如mirror.centos.org）替换为mirrors.tuna.tsinghua.edu.cn。
对于CentOS 8，请把mirror.centos.org/$contentdir替换为mirrors.tuna.tsinghua.edu.cn/centos。

通过该命令亦可一步完成

# 对于 CentOS 7
sudo sed -e 's|^mirrorlist=|#mirrorlist=|g' \
         -e 's|^#baseurl=http://mirror.centos.org|baseurl=https://mirrors.tuna.tsinghua.edu.cn|g' \
         -i.bak \
         /etc/yum.repos.d/CentOS-*.repo

# 对于 CentOS 8
sudo sed -e 's|^mirrorlist=|#mirrorlist=|g' \
         -e 's|^#baseurl=http://mirror.centos.org/$contentdir|baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos|g' \
         -i.bak \
         /etc/yum.repos.d/CentOS-*.repo

其中*通配符，人工只需要替换一些文件中的源，请自行增删。
注意，如果需要启用一些repo，需要将其中的enabled=0改为enabled=1。
最后更新软件包缓存

sudo yum makecache
