next.js + pm2

创建ecosystem.config.js

module.exports = {
  apps: [{
    name: 'wangyu',
    script: './server.js',
    instances: 4,
    max_restarts: 7,
    env: {
      NODE_ENV: 'production',
      NODE_PORT: 8080,
      REACT_APP_ENV: 'test',
    },
    watch: false,
    merge_logs: true,
    exec_mode: 'cluster',
    max_memory_restart: '600M',
    instance_var: 'NODE_APP_INSTANCE',
  }]
}

创建server.js
https://nextjs.org/docs/advanced-features/custom-server

const { parse } = require('url');
const next = require('next');
const express = require('express');
const server = express();
const NODE_PORT = process.env.NODE_PORT;

const dev = process.env.NODE_ENV !== 'production';
const app = next({ dev });

app.prepare().then(() => {
  server.get('*', (req, res) => {

    const parsedUrl = parse(req.url, true);
    const { pathname, query } = parsedUrl;

    // 主页
    if (pathname === '/wangyu/index') {
      return app.render(req, res, '/', query);
    }
   // ... 其它页面
    app.render(req, res, '/404', query);
  })

  server.listen(NODE_PORT, () => console.log('Example app listening on port ' + NODE_PORT));
})

修改npm script

"server_start": "pm2 start ecosystem.config.js",
"server_reload": "pm2 reload ecosystem.config.js",
"server_stop": "pm2 stop ecosystem.config.js"
