Conda和Python的国内安装源

Windows系统：

更换python国内源的方法。
在“C:\Users[xxxx]\pip\pip.ini”文件中配置如下内容（没有则新建，xxx代表当前用户目录）：

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host=mirrors.aliyun.com

更换conda的国内源的方法，终端命令输入如下：

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --set show_channel_urls yes

在windows下可以修改“C:\Users[xxxx].condarc”文件如下内容：
channels:

• - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
  - defaults
    show_channel_urls: true
    ssl_verify: true

换回默认源：

conda config --remove-key channels

linux系统：

更换python国内源的方法。
在“~/.pip/pip.conf”文件中配置如下内容（没有则新建）.执行以下命令

vim  ~/.pip/pip.conf

输入如下内容：

[global]
index-url = http://pypi.douban.com/simple
trusted-host = pypi.douban.com

更换conda的国内源的方法（同Windows系统设置）。
修改apt-get源的方法。
（1）执行如下命令，先备份，再修改“/etc/apt/sources.list”的文件：

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
sudo vi /etc/apt/sources.list

（2）复制对应版本的源地址：https://mirror.tuna.tsinghua.edu.cn/help/ubuntu/

（3）最后执行更新：

sudo apt-get update

Centos的yum源跟换为国内的阿里云源
（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 5

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo

CentOS 6

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

CentOS 7

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

3、运行生成缓存

yum makecache
