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]pippip.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 = http://pypi.douban.com/simple
[install]
trusted-host = pypi.douban.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
cd ~ &&mkdir .pip &&cd .pip &&vim 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
