瓶，Nginx等uwsgi

Question

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的并运行此：

sudo uwsgi -s /tmp/uwsgi.sock --module myapp --callable app 这是输出

但尚未我得到的是一个502错误...任何我怎样才能解决这一问题？

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

您正在运行uWSGI为根（为什么???），所以/tmp/uwsgi.sock将属于root而nginx通常作为nobody或www-data运行。

如果你不想考虑使用TCP套接字的权限，但显然不要以root身份运行你的应用程序。
