使用 gunicorn 和 Nginx 服务多个套接字会导致 NotFound 错误

772

我正在尝试使用 Nginx 作为反向代理来提供两个 Flask 应用程序。在我default.conf 重新加载的sudo service nginx restart我有：

    location /app2loc/ {
            include proxy_params;
            proxy_pass http://unix:/var/www/html/app2/app.sock;
    }
    location / {
            include proxy_params;
            proxy_pass http://unix:/var/www/html/app1/app.sock;
    }

当app1我在www.mydomain.com. 第二个应用程序app2似乎运行有任何错误作为证据，这是输出sudo systemctl status app2.service：

● app2.service - Gunicorn instance to serve Flask app2.
   Loaded: loaded (/etc/systemd/system/capitcatalog.service; enabled; vendor preset: enabled)

但是，当我尝试使用它访问它时，www.mydomain.com/app2loc我有一个

Not Found
The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.

我想知道可能是什么错误。为什么第二个套接字似乎无法访问？

第二个是可访问的，并且该套接字上的应用服务器返回“未找到”错误。

最有可能发生这种情况是因为 nginx 会将请求转发/app2loc到您的第二个应用程序服务器。

将 app2 的更改proxy_pass为：

location /app2loc/ {
    proxy_pass http://app2/;
}

upstream app2 {
    server unix:/var/www/html/app2/app.sock;
}

/末尾的额外内容proxy_pass使 nginxapp2loc从传递给上游的 URI 中剥离前缀。

还要记住配置应用程序的基本 URL 以包含app2loc前缀。
