node.js - 为 bluehost 服务器设置 Node.js 端口

Question

我正在尝试通过 cpanel 在我的 bluehost VPS 上部署 node.js 和 express 网站，但是尽管部署了 git repo，并且应用程序是通过应用程序管理器注册的，并且在访问唯一的 URL 时确保了 npm 依赖项您可以看到我的 public_html node_modules 和视图中的 2 个文件——但 git repo 的其余部分没有显示。

我觉得我的 app.js 中没有设置正确的端口，因为我认为 cpanel.yml 文件是正确的。我在想它仍然只是试图连接到 3000 也许？任何帮助都会很棒。

app.js 如下：

// //jshint eversion:6

const http = require('http')
const express = require("express");
const bodyParser = require("body-parser")

const ejs = require('ejs');
const nodemailer = require('nodemailer');
const hostname = '127.0.0.1';
const path = require('path');
const port = 3000;


const app = express();


app.set("view engine", "ejs");
app.use(bodyParser.urlencoded({
    extended: false
}));
app.use(express.json());



// custom middleware to log data access
const log = function (request, response, next) {
    console.log(`${new Date()}: ${request.protocol}://${request.get('host')}${request.originalUrl}`);
    console.log(request.body); // make sure JSON middleware is loaded first
    next();
}
app.use(log);
// end custom middleware


app.use(express.static('public'));
app.use(express.static('images'));



app.get("/", function (req, res) {
    res.render("index");
});

app.get("/prices", function (req, res, ) {
    res.render("prices");
});

app.get("/about", function (req, res, ) {
    res.render("about");
});
app.get("/contact", function (req, res, ) {
    res.render("contact");
});

module.exports = function () {
    this.Categories = require('tools.js');
}



// HTTP POST
app.post("/ajax/email", function (request, response) {
    // create reusable transporter object using the default SMTP transport
    const transporter = nodemailer.createTransport({
        host: "smtp.gmail.com",
        port: 465,
        secure: true,
        auth: {
            user: "[e-mail]", // this should be YOUR GMAIL account
            pass: "xxxx" // this should be your password
        }
    });

    var textBody = `FROM: ${request.body.fname}  EMAIL: ${request.body.email} MESSAGE: ${request.body.comment}`;
    var htmlBody = `<h2>Mail From Contact Form</h2> <p>From: ${request.body.fname} ${request.body.lname} </p> <p> Email: ${request.body.email}</p> <p> Phone Number: ${request.body.phone}</p> <p> Company: ${request.body.company}</p><p>Comment: ${request.body.comment}</p>`;
    var mail = {
        from: "xxx", // sender address
        to: "XXX", // list of receivers (THIS COULD BE A DIFFERENT ADDRESS or ADDRESSES SEPARATED BY COMMAS)
        subject: "Mail From Contact Form", // Subject line
        text: textBody,
        html: htmlBody
    };

    // send mail with defined transport object
    transporter.sendMail(mail, function (err, info) {
        if (err) {
            console.log(err);
            response.json({
                message: "message not sent: an error occured; check the server's console log"
            });
        } 
    });
});


const PORT = process.env || port;


const server = http.createServer((req, res) => {
    res.statusCode = 200;
    res.setHeader('Content-Type', 'text/plain');
    res.end('Hello World! NodeJS \n');
});

app.listen(port, hostname, () => {
    console.log(`Server running at http://${hostname}:${port}/`);
});

您const port = 3000;默认使用。

所以用

const PORT = process.env.PORT || port;

并使用PORT而不是port这样做

app.listen(PORT, hostname, () => {
    console.log(`Server running at http://${hostname}:${PORT }/`);
});
