<name>Human Readable Name for this Mirror.</name>
<url>https://repo.spring.io/libs-snapshot/</url>
</mirror>
具体操作
打开 ${maven_home}/conf/settings.xml
在<mirrors>上面配置上面的国内源（一般阿里源）
注意：idea使用的时候将Maven选择正确再使用
pip换源
首先列出常见的国内源
阿里云 http://mirrors.aliyun.com/pypi/simple/
中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/
豆瓣(douban) http://pypi.douban.com/simple/
清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/
中国科学技术大学 http://pypi.mirrors.ustc.edu.cn/simple/
注意：pip源貌似豆瓣的还不错，不一定厂大就香。
临时使用
可以使用pip install 包名 -i 源地址 的方式临时加速下载pip包
长期使用
windows建议在user目录（一般是C:\Users\xxx（用户名）目录）下新建pip目录，cd后新建pip.ini文件，写添加如下命令
[global]
index-url=http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host=mirrors.aliyun.com
Linux建议立~/.pip/pip.conf文件，添加如下命令
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
npm换源
国内镜像
淘宝npm：http://registry.npm.taobao.org/
cnpmjs镜像：http://r.cnpmjs.org/
临时使用
npm --registry 镜像地址 install 包名
持续使用
通过npm config set registry 镜像地址设置源
通过cnpm
通过npm install -g cnpm --registry=[https://registry.npm.taobao.org]来安装cnpm
cnpm -v 来测试是否成功安装
通过nrm
安装
npm install -g nrm
使用
nrm ls //可以列出所有源，前面带 * 号的表示正在使用的源
nrm use npm //切换使用的源
nrm add <registry> <url> //添加一个源
nrm del <registry> //删除一个源
nrm test <源名> //测试速度
docker换源
登陆阿里云控制台，获得专属加速通道
修改daemon配置文件/etc/docker/daemon.json来使用阿里加速器，代码如下
{
"registry-mirrors": ["您的加速码"]
}
命令打出sudo systemctl daemon-reload
命令打出sudo systemctl restart docker
yum换源
CentOS7的yum源的替换大致分为三步：备份，替换，更新
备份
首先备份 CentOS-Base.repo
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
替换
将国内镜像仓库信息写入 /etc/yum.repos.d/CentOS-Base.repo
vim /etc/yum.repos.d/CentOS-Base.repo
以下为国内源
- sohu的源：
http://mirrors.sohu.com/help/CentOS-Base-sohu.repo - 163的源：
http://mirrors.163.com/.help/CentOS6-Base-163.repo - 阿里云的源：
http://mirrors.aliyun.com/repo/Centos-7.repo
更新
yum clean all # 清除系统所有的yum缓存
yum makecache # 生成yum缓存
apt-get换源
备份
sudo cp /etc/apt/sources.list /etc/apt/sources.list.back
更换
编辑/etc/apt/sources.list文件
sudo vi /etc/apt/sources.list
在文件最前面添加国内源，知名的国内源如下
