Setting up a Next.js application on DirectAdmin

[farhadnabi]

I developed an application using Next.js and deployed it on my own hosting, which utilizes the DirectAdmin panel. I run my application through NGINX Unit as described in this link: https://nextjs.org/docs/pages/building-your-application/configuring/custom-server. However, it's giving me a 503 error. I would appreciate your guidance to resolve the issue.

i try run my application

when you running with nginx unit, you must create app with pure standalone wkthout running on port or unix socket .... something like this

#!/usr/bin/env node
var unit = require('unit-http');
var server = unit.createServer(function(request, response) {
    response.writeHead(200, {"Content-Type": "text/html"});
    response.end("Read more at unit.nginx.org");

});
server.listen();

i use this code :

const { createServer } = require('http')
const { parse } = require('url')
const next = require('next')

const dev = process.env.NODE_ENV !== 'production'
const hostname = 'localhost'
const port = process.env.port || 3000
// when using middleware `hostname` and `port` must be provided below
const app = next({ dev, hostname, port })
const handle = app.getRequestHandler()

app.prepare().then(() => {
    createServer(async (req, res) => {
        try {
            // Be sure to pass `true` as the second argument to `url.parse`.
            // This tells it to parse the query portion of the URL.
            const parsedUrl = parse(req.url, true)
            const { pathname, query } = parsedUrl

            if (pathname === '/a') {
                await app.render(req, res, '/a', query)
            } else if (pathname === '/b') {
                await app.render(req, res, '/b', query)
            } else {
                await handle(req, res, parsedUrl)
            }
        } catch (err) {
            console.error('Error occurred handling', req.url, err)
            res.statusCode = 500
            res.end('internal server error')
        }
    })
        .once('error', (err) => {
            console.error(err)
            process.exit(1)
        })
        .listen(port, () => {
            console.log(`> Ready on http://${hostname}:${port}`)
        })
})

If I have missed something, please help me

change "require('http')" to "require('unit-http')"

and set "port=null"
maybe it should work. otherwise if I have time to playing, I will test for you.

I never use next.js, only pure standalone http.
