javascript - Openshift不会运行nodejs应用程序

Question

我试图在我的 openshift 服务器上使用 socket.io 运行我的聊天程序，但是每当我尝试重新加载它给我的链接时，它只是一直说:“503 服务错误”。我已经正确设置了我的存储库，并使用 rhc 客户端将我的 ssh key 输入到 openshift 中，但无济于事，我使用端口 3000，我也尝试了端口 80，但它们都不起作用。

这是我的服务器代码和我的 package.json:

var express = require("express"),
    app = express(),
    http = require("http").Server(app),
    io = require("socket.io")(http),
         require("./index.js");

app.use(express.static("static"));

io.on("connection", function(socket) {
    console.log("a user connnected");
    socket.on("disconnect", function() {
        console.log("user disconnected");
    });

    socket.on("chat message", function(msg) {
        console.log("message " + msg);
        io.emit("chat message", {m: msg.m, u: msg.u});
    });
});


var port;

if(process.argv[2]) {port = process.argv[2]} else {port = 3000}

http.listen(port, function() {
    console.log("chat listening on port " + port + ".");
});

还有我的 package.json:

{
  "name": "ChatterBox",
  "version": "1.0.0",
  "description": ".",
  "main": "index.js",
  "dependencies": {
  "express": "^4.12.3",
  "socket.io": "^1.3.5"
},
  "devDependencies": {},
"scripts": {
  "test": "echo \"Error: no test specified\" && exit 1"
