将Flask应用程序部署在nginx,tornado的简单方法

前言

这不是一个好方法.但是可以用\简单\性能将就\Windows支持.大神可以参考官方文档进行部署.

flask代码:main.py

from flask import Flask  
app = Flask(__name__)  
 
@app.route('/')  
def hello_world():  
    return 'Hello World!'  
  
if __name__ == '__main__':  
    app.run(debug=True)  

tornado 代码:run.py

from tornado.wsgi import WSGIContainer  
from tornado.httpserver import HTTPServer  
from tornado.ioloop import IOLoop  
#导入flask项目  
from main import app  
  
http_server = HTTPServer(WSGIContainer(app))  
http_server.listen(5000)#对应flask的端口  
IOLoop.instance().start()  
  
#如果要开启多进程模式用下面的代码，不过仅在linux下 
# http_server = HTTPServer(WSGIContainer(app))  
# http_server.bind(8888)  
# http_server.start(0)  
# IOLoop.instance().start()  

Windows 不支持多进程解决方案(重复启动,监听多端口)

from tornado.wsgi import WSGIContainer  
from tornado.httpserver import HTTPServer  
from tornado.ioloop import IOLoop  
from tornado.options import define, options
import tornado.options
#导入flask项目  
from main import app  

define("port", default=5000, help="run on the given port", type=int)
  
http_server = HTTPServer(WSGIContainer(app))  
http_server.listen(options.port)#对应flask的端口  
IOLoop.instance().start()  

windows 启动脚本

python run.py --port=5001
python run.py --port=5002
python run.py --port=5003

修改nginx配置文件：

server {  
        listen       80; 
        server_name  localhost;  
   
        location / {   
            proxy_pass http://localhost:5000; #添加这句，指向flask  
        } 
        }

window 解决方案

upstream run {
        server localhost:5001;
        server localhost:5002;
		server localhost:5003;

    }
server {  
        listen       80; 
        server_name  localhost;  
  
        location / {  
            proxy_pass  http://run #添加这句，指向flask  
        } 
    }

启动 run.py 和 nginx

搞定收工,可以打开浏览器看一下效果,也可以用apache-jmeter 测试一下.
