HomeBackend DevelopmentPython Tutorial在DigitalOcean的服务器上部署flaskblog应用

在DigitalOcean上部署了flaskblog,项目虽小,部署中也学到了很多东西。
操作系统选择的是Ubuntu14.04,原因就是平时自己主要使用这个版本,顺手而已,所以你自己可以根据需要选择合适的linux版本。
部署方案:

Virtualenv+Gunicorn+Nginx+Supervisor

从这里下载项目的代码flaskblog, 工程中带有简单的配置文件参考。
可以先访问flaskblog看一下。
注意

本文中使用Ubuntu14.04 64位主机, 创建一个名为xin的用户,进行部署。
本文重点部署,所有linux的相关操作不做详细介绍。
部署目录是(/home/xin/www/flaskblog),所以请注意配置文件中的目录。
环境

系统:Ubuntu 14.04 64
Web Server: Nginx
虚拟环境: Virtualenv
WSGI Server: Gunicorn
数据库: MySQL
Monitor: Supervisor
使用supervisor主要是监控gunicorn的运行,保证服务器的可以持续运行。

安装

安装软件

$ sudo apt-get install python-pip 
$ sudo apt-get install python-dev    
$ sudo pip install virtualenv    
$ sudo apt-get install mysql-server  
$ sudo apt-get install libmysqlclient-dev 
$ sudo apt-get install nginx  
$ sudo apt-get install supervisor 

 
下载工程并开启虚拟环境

使用git下载代码到(/home/xin/www/flaskblog)

$ git clone https://github.com/defshine/flaskblog.git 
$ cd flaskblog   

 
启动虚拟环境,安装工程依赖

$ virtualenv venv  
$ source venv/bin/activate  
(venv)$ pip install -r requirements.txt  

如何退出虚拟环境

(venv)$ deactivate 

数据库

在MySQL数据库中创建数据库(flaskblog),修改 config.py中的数据库的配置
初始化数据库并创建管理员用户

(venv)$ python manage.py create_db 
(venv)$ python manage.py create_user -u admin -p 123456 

开启监控

根据自己的情况,编辑工程下的supervisor配置文件(flaskblog.conf),然后复制到系统目录中

$ sudo cp flaskblog.conf /etc/supervisor/conf.d/ 

重新载入配置文件,并启动flaskblog

$ sudo supervisorctl reload 
$ sudo supervisorctl start flaskblog 

查看运行状态

$ sudo supervisorctl status 

Nginx

修改nginx的配置文件(flaskblog),然后复制到系统目录中去,并创建软链接。重启nignx。

$ sudo cp flaskblog /etc/nginx/site-available/ 
$ cd /etc/nginx/site-enabled 
$ sudo ln -s /etc/nginx/site-avalaible/flaskblog . 
$ sudo service nginx reload 
$ sudo service nginx restart 

查看nginx状态

$ sudo service nginx status 

然后,就可以通过ip地址访问了。当然,配置好域名,访问起来更好。
flaskblog这个小项目,刚刚有个小雏形,后续还可以开发一些小特性。
