使用 uwsgi + nginx 将 Flask 应用程序与 Django 应用程序一起部署

Question

我正在尝试在当前部署了 django 应用程序的服务器中部署一个简单的 flask 应用程序。

django 应用程序工作正常，但 flask 应用程序显示 404 错误，尽管我已经完成了正确的设置并且我没有在日志中看到任何错误。

目前，这是我的 app2.ini 文件

我的app.py:

from flask import Flask
app = Flask(__name__)

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

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

wsgi.py

from flaskapp.app import app

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

nginx 配置文件：

server {
    listen *:80;
    listen [::]:80;

    server_name mysite.com;

    # Let's Encrypt
    location /.well-known/acme-challenge/ {
        root /var/www/html;
    }

    # Everything else -> SSL
    location / {
        return 301 https://$host$request_uri;
    }
}


server {
    listen 443;
    listen [::]:443;

    server_name mysite.com;

    access_log  /var/log/nginx/access.log;

    ssl on;
    ssl_certificate      /etc/letsencrypt/live/mysite.com/fullchain.pem;
    ssl_certificate_key  /etc/letsencrypt/live/mysite.com/privkey.pem;

    client_max_body_size 256m;

    location / {
        try_files $uri @uwsgi;
    }

    location @uwsgi {
        include uwsgi_params;
        uwsgi_pass unix:/home/app/app/uwsgi.sock;
    }

    location /flask/ {
        include uwsgi_params;
        uwsgi_pass unix:/home/app2/app/flaskapp/uwsgi.sock;
    }
}

我的app2.ini文件：

[uwsgi]
socket = /home/app2/app/flaskapp/uwsgi.sock
chdir = /home/app2/app
wsgi-file = flaskapp/wsgi.py
touch-reload = flaskapp/wsgi.py
venv = /home/app2/pyvenv
processes = 4
threads = 2
chmod-socket = 666
daemonize=true
vacuum = true
uid = app2
gid = app2
callable = app

树：

flaskapp
├── app.py
├── __init__.py
├── __pycache__
│   ├── app.cpython-35.pyc
│   └── __init__.cpython-35.pyc
├── uwsgi.sock
└── wsgi.py

当我尝试访问我的站点时，一切似乎都正常。com/flask这是 uwsgi 日志文件的输出

当我尝试访问我的网站时 nginx.log 文件。com/flask:

如果您看到什么请告诉我，我一直在努力解决它，但不知道我还能做什么。

好吧，如果其他人遇到这个问题，我设法通过在 /flask 位置包含这个 conf 来做到这一点：

location /flask {
    rewrite ^/flask(.*)  break; # IMPORTANT!
    include uwsgi_params;
    uwsgi_pass unix:/home/app2/app/flaskapp/uwsgi.sock;
}
