Linux 系统操作简记 -- 修改Ubuntu apt-get 与 pip更新源，提高安装速度

另外由于默认安装时的源大都是外国的更新源，速度相对国内会慢很多，接下来主要介绍在ubuntu系统中更新系统源的方法，以Ubuntu 14.04 为例
1. 修改apt-get 更新源

 sudo vim /etc/apt/sources.list

清空，输入阿里巴巴的更新源

deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

然后更新

sudo apt-get update

2 . 更改pip更新源
在主目录下创建.pip文件夹

mkdir ~/.pip

在.pip文件夹下新建一个pip.conf文件,编辑

vim pip.conf

输入 豆瓣源
