1 install vue/django/npm

安装了npm之后（使用淘宝的镜像）http://www.jianshu.com/p/6e65d8cad6d4
安装vue 和 django ，直接运行命令行
环境：Ubuntu （阿里云）
虚拟环境： workon dv

1. vue安装

cnpm install -g vue-cli

2. django安装

pip install django

3. mysql安装
   使用mysql替换django原来的数据库sqlite3

(1) sudo apt-get install mysql-server mysql-client  #全局
(2) sudo apt-get install libmysqlclient-dev  #全局 ubuntu
      yum install python-devel mysql-devel#全局 centos
(3) pip install MySQL-python  #dv 环境

查看状态，是否安装成功。

sudo service mysql status

连接报错：

root@JoJo:~# sudo mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

如果不执行第二条语句，ubuntu安装MySQL-python就会报以下错误：

如果第二条centos中，没有安装python-devel，会有如下报错： (yum install python-devel 就ok了)
