瓶，Nginx等uwsgi(Flask, nginx, and uwsgi)

我的瓶的应用程序看起来像这样...
myapp.py

from flask import Flask  
app = Flask(__name__) 

@app.route("/")  
def hello():  
   return "Hello World!"  

if __name__ == "__main__":  
   app.run('0.0.0.0')

我的nginx的设置

server {
         root /home/admin.jeremylspencer.com;
         server_name admin.jeremylspencer.com;

         location / { try_files $uri @yourapplication; } 
         location @yourapplication {
                 include uwsgi_params;
                 uwsgi_pass unix:/tmp/uwsgi.sock;
         }       

         #error_page 404 /404.html;
         #error_page 500 502 503 504 /50x.html;
         location = /50x.html {
                 root /usr/share/nginx/www;
         }        
         location ~ /\.ht {
                 allow all;
         }
}

于是最后我重启nginx的和运行这个：

须藤uwsgi -s /tmp/uwsgi.sock --module MYAPP --callable应用程序，这是输出

但是，还没有我得到的是一个502错误...任何我怎样才能解决这一问题？

Answer 1:

Unix套接字文件系统对象，所以nginx的需要写入权限/tmp/uwsgi.sock

您正在运行uWSGI为根（为什么???），所以/tmp/uwsgi.sock将根而nginx的一般以nobody运行或www数据所拥有。

如果你不想参加的帐户权限只使用TCP套接字，但显然不运行你的应用程序的根目录。

你可以在此看： nginx的和uWSGI的Python瓶为回购提供了有关如何在生产模式下使用瓶的确切情况/场景。
