本文介绍了用Nginx反向代理Node.js的方法，分享给大家，具体如下：
安装pm2

"test": "echo \"Error: no test specified\" && exit 1",
"pm2": "/home/download/node-v8.11.1-linux-x64/lib/node_modules/pm2/bin/pm2 start /web/mazey.cn/server/app.js"
}

"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"pm2": "pm2 start app.js"
}
|
启动pm2
|

|
npm run pm2
|
开机启动pm2

注意
若 pm2 startup centos 失败，可尝试 pm2 startup 。

PM2 detected systemv but you precised centos
Please verify that your choice is indeed your init system
If you arent sure, just run : pm2 startup

const express = require('express')
const app = express()
let hi = 'hi'
app.get('/server', (req, res, next) => {
hi = `Hello Mazey!\n`
next()
}, (req, res) => {
res.send(`
${hi}
${req.method}\n
${req.originalUrl}\n
${req.query.id}\n
`)
})
const server = app.listen(3000, function () {
let host = server.address().address
let port = server.address().port
console.log('Example app listening at http://%s:%s', host, port)
})

注意
若报错 Cannot GET /xxx 说明 Express 的路由没配好。
