gunicorn+flask使用与配置

gun.conf的内容

import os
bind = '10.1.240.222:5000'
workers = 4
backlog = 2048
worker_class = "sync"
debug = True
proc_name = 'gunicorn.proc'
pidfile = '/tmp/gunicorn.pid'
logfile = '/var/log/gunicorn/debug.log'
loglevel = 'debug'

tests.py 的内容

rom flask import Flask
from flask import render_template_string
import os
from werkzeug.contrib.fixers import ProxyFix
app = Flask(__name__)
@app.route('/')
def index():
    return "worked!"
app.wsgi_app = ProxyFix(app.wsgi_app)
if __name__ == '__main__':
    app.run()

注意要在nginx.conf中配置一个反向代理，监听5000端口，内容如下：

启动脚本：gunicorn -c gun.conf  run_test:app
