在uwsgi/nginx上運行燒瓶應用程序的問題

我已經創建了燒瓶應用程序，並且到目前爲止，已經使用默認燒瓶服務器來創建/測試它。現在我想將其部署到服務器。我正在使用uwsgi和nginx，但我對兩者都很新穎。我知道有很多的指南以及有關類似的事情的問題，但是我無法找到通過儘可能多的尋找後的解決方案，我可以理解在uwsgi/nginx上運行燒瓶應用程序的問題

以下是從我的uwsgi日誌：

*** uWSGI is running in multiple interpreter mode ***

我假設uwsgi至少運行？我對此很新，所以我不太確定問題所在。

我的nginx的配置是：

server{ 

    listen 8080; 
    charset utf-8; 

    location/{try_files $uri @app; } 
    location @app { 
     include uwsgi_params; 
     uwsgi_pass unix:/home/ben/flask/MLS-Flask/mls_uwsgi.sock; 
    } 
}

我uwsgi INI是：

[uwsgi] 

uid = nginx 
gid = nginx 

base = /home/ben/flask/MLS-Flask 

home = %(base)/mls-flask-ve 
pythonpath = %(base) 

chdir = /home/ben/flask/MLS-Flask 

module = runp 

#socket file's location 
socket = /home/ben/flask/MLS-Flask/mls_uwsgi.sock 

#permissions for the socket file 
chmod-socket = 666 

#variable that holds a flask application inside the module imported 
callable = app 

#location of log file 
logto = /var/log/uwsgi/%n.log

和uwsgi INI運行該文件是我的瓶的應用程序：

from app import app 


if __name__ == "__main__": 
    app.run(debug = False, port = 8080)

我可能在我的uwsgi ini或nginx配置中有一些無關的東西，但我不確定這些是否會成爲問題。任何人都可以看到任何原因，爲什麼這可能不工作？我目前在localhost：8080上得到了一個502錯誤的網關錯誤，所以我猜測它與我的燒瓶uwsgi ini/socket有關。

我很感激任何幫助。

我發佈了這個問題前一陣子，看看你是否能從中得到一些東西。 http://stackoverflow.com/questions/17112805/deploying-a-flask-app-to-hosting-at-godaddy – zee

事實證明，我的nginx用戶沒有權限訪問套接字，因爲/和/ home /目錄屬於根組和root用戶。我最終完全訪問了所有者並將其從/目錄中全部路由到套接字（這可能不是最安全的解決方案安全方面的明智之舉，但是在我使所有工作後我可以進一步優化它）。
