Openshift不會運行Node.js應用程序

Question

我試圖在openshift服務器上使用socket.io運行我的聊天程序，但是每當我嘗試重新加載它給我的鏈接時，它總是說：“ 503服務錯誤”。 我已經正確設置了我的存儲庫，並使用rhc客戶端將ssh密鑰輸入到openshift中，但無濟於事，我使用的是端口3000，我也嘗試了端口80，但它們都不起作用。

這是服務器和package.json的代碼：

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 + ".");
});

還有我的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"

請參閱OPENSHIFT_NODEJS_PORT環境變量（以及頁面底部的示例用法）： https : //developers.openshift.com/en/node-js-environment-variables.html

使用$ OPENSHIFT_REPO_DIR代替$ relative_path_from_repo_dir
