国内服务器加速安装的方法？换源和镜像站的使用？

国内服务器软件加速的典型方案：

系统级换源
- Ubuntu用sed -i 's/archive.ubuntu.com/mirrors.aliyun.com/g' /etc/apt/sources.list
- CentOS替换baseurl=http://mirrors.tencentyun.com/centos/$releasever
容器镜像加速
- Docker配置"registry-mirrors": ["https://[阿里云镜像ID].mirror.aliyuncs.com"]

加速场景	推荐镜像源	配置检测
Python PIP	`-i https://pypi.tuna.tsinghua.edu.cn/simple`	`pip config list`
NPM	`npm config set registry https://registry.npmmirror.com`	`npm get registry`
Composer	`composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/`	`composer config -gl`
Maven	修改`settings.xml`中的`<mirror>`标签	`mvn help:effective-settings`
