下面是这个过程的概要：
步骤1：开始设置一个自定义的Next.js服务器。您需要在项目的根目录中创建一个server.js文件，并填充所需的代码。查找官方Next.js指南以获得帮助。

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

const dev = process.env.NODE_ENV !== 'production'
const hostname = 'localhost'
const 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}`)
})
})

第2步：调整package.json文件。此步骤使环境“生产就绪”并激活server.js文件。

{
"scripts": {
"start": "NODE_ENV=production node server.js"
}
}
