uWSGI +nginx 设置 - Dash（Plotly）部署

Question

我 \xe2\x80\x99m 是 Fl​​ask 和部署过程的新手\n我的 dash.py 设置如下

\n\n

server = flask.Flask(__name__)\napp = dash.Dash(__name__, server=server)\n

\n\n

和我的 nginx 文件

\n\n

server {\nlisten      80;\nserver_name localhost;\ncharset     utf-8;\nclient_max_body_size 75M;\n\nlocation / {try_files $uri @yourapplication; }\nlocation @yourapplication {\n    include uwsgi_params;\n    uwsgi_pass unix:/var/www/School-Dashboard/dash_clean.sock;\n}\n}\n

\n\n

\xe2\x80\xa6but i\xe2\x80\x99m 不确定我必须在 wsgi ini 文件中设置模块参数。

\n\n

[uwsgi]\n#application's base folder\nbase = /var/www/School-Dahboard\n\n#python module to import\nmodule = dash_clean:app #?????? WHAT DO I DO HERE\n\n#home = %(base)/venv\npythonpath = %(base)\n\n#socket file's location\nsocket = /var/www/School-Dashboard/dash_clean.sock\n\n#permissions for the socket file\nchmod-socket    = 660\n\n\n#location of log files\nlogto = /var/log/uwsgi/%n.log\n

\n\n

由于我的 uwsgi 文件，我不断收到错误的网关错误。

\n\n

这是来自 uwsgi 的日志。

所以我已经将 nginx 设置为这样......

server {
        server_name 0.0.0.0;
        listen 80;
        root /home/ubuntu/school_dashboard;
        client_max_body_size 200M;
        include /etc/nginx/default.d/*.conf;

location /dependencies {
   proxy_read_timeout 300;
    proxy_connect_timeout 300;
   proxy_pass http://0.0.0.0:5005;
        #index wsgi.py
        include uwsgi_params;
       uwsgi_pass unix:/home/ubuntu/school_dashboard/dependencies/urlgen.sock;
    }
}

我的 uwsgi 文件为......

[uwsgi]
module = dash_clean:server

master = true
processes = 5

socket = dashboard.sock
chmod-socket = 660
vacuum = true

die-on-term = true

我只需更改模块参数
