passenger 5.1.11更新，节点socket.io错误

Question

从 passenger 1:5.1.5-1~jessie1 更新到这个新版本后。我们在浏览器中收到以下错误：

Failed to load https://aaa.bbb.com/socket.io/?hash=1735f35ec0ad4e4d91618861288467ed&EIO=3&transport=polling&t=LzIr1i8: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://aaa.bbb.com' is therefore not allowed access. The response had HTTP status code 404.

nginx 错误日志：

2017/10/25 11:42:24 [error] 638#638: *20 "/export/home/aaa.bbb.com/public/socket.io/index.html" is not found (2: No such file or directory), client: 111.111.111.111, server: aaa.bbb.com, request: "GET /socket.io/?hash=1735f35ec0ad4e4d91618861288467ed&EIO=3&transport=polling&t=LzIwLNC HTTP/1.1", host: "aaa.bbb.com", referrer: "https://ccc.bbb.com/mmmm/zzzz/"

如您所见，我们正在使用 socket.io (1.5.1)。我们的 socket.io 服务器安装了 node.js (v6.11.5) 和 passenger (5.1.11)。

我们以前从未需要设置原点。 Web 服务器和套接字服务器都在同一个域中，只是不同的子域。

但 nginx 日志中的错误可能才是真正的问题。

编辑

我已将客户端和服务器端的 socket.io 更新到版本 2.0.4。但是我运行还是陷入同样的错误

乘客在启动时坠毁。可能是权限问题。

Answer 1

在更新之前，我将 passenger_user_switching 设置为关闭。这使得乘客进程自动运行为 nobody:noboby

passenger_user_switching off;

更新后，我将 passenger_user 和 passenger_group 明确设置为运行作为 nobody:noboby（默认 passenger_user_switching 开启）

# passenger_user_switching off;
passenger_user nobody;
passenger_group nobody;
