在uwsgi / nginx上运行烧瓶应用程序时出现问题

Question

我已经创建了一个flask应用，到目前为止，已经使用默认的flask服务器来创建/测试它。现在，我想将其部署到服务器上。我正在使用uwsgi和nginx，尽管我对两者都相当陌生。我知道有很多关于类似事物的指南和问题，但是经过我的理解后，我找不到解决方案

以下是我的uwsgi日志中的内容：

我假设uwsgi至少正在运行？我对此很陌生，所以我不太确定问题出在哪里。

我的nginx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;
    }
}

我的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

并且uwsgi ini正在运行的文件是我的烧瓶应用程序：

from app import app


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

我的uwsgi ini或nginx配置中可能有一些无关紧要的东西，但是我不确定这些是否一定是问题所在。谁能看到任何原因导致它不起作用？我目前在localhost：8080上收到502错误的网关错误，所以我猜想它与我的烧瓶uwsgi ini / socket有关。

我非常感谢您的帮助。

Answer 1

事实证明，我的nginx用户无权访问套接字，因为/和/ home /目录归root组和root用户所有。我最终从/目录到套接字一直对所有者和组具有完全访问权限（这可能不是最安全的解决方案安全性，但是在一切正常之后，我可以进一步完善它。）

Answer 2

我有同样的问题：

1. 总是使用ls -lhtr检查套接字权限
2. 尝试将套接字放入/run/myapp/mysock.sock文件夹中>
3. 在此文件夹vi mysock.sock中创建一个空的袜子文件
4. 设置此空文件的权限，以使您的用户和组具有完全访问权限在服务中。 chown user:group /run/myapp/mysock.sock
