flask tornado nginx 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()

修改nginx配置文件，nginx.conf：

server {
listen 9900; #默认是80,我改成了9900
server_name localhost;

    #charset koi8-r;

    #access_log  logs/host.access.log  main;

    location / {
        root   html;
        index  index.html index.htm;
        proxy_pass http://localhost:5000; #添加这句，指向flask
    }

启动 run.py 和 nginx，打开浏览器：

输入nginx的IP和端口指向了flask项目
