本篇文章主要介绍了用Nginx反向代理Node.js的方法,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧

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

npm install pm2 -g

ln -s /home/download/node-v8.11.1-linux-x64/lib/node_modules/pm2/bin/pm2 /usr/local/bin/pm2

修改package.json

"scripts": {
  "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"
}

or

"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

pm2 save

pm2 startup centos

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

修改Nginx配置

vim /etc/nginx/conf.d/*.conf

upstream nodejs {
  server 127.0.0.1:3000;
  keepalive 64;
}
server {
  listen 80;
  server_name domain.cn;
  root /web/mazey.cn;
  index index.html index.htm;
  # 网站切到/server下时走nodejs
  location /server {
    proxy_set_header  X-Real-IP $remote_addr;
    proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header  Host $http_host;
    proxy_set_header  X-Nginx-Proxy true;
    proxy_set_header  Connection "";
    proxy_pass http://nodejs;
  }
  location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ {
    expires 30d;
  }
  location ~ .*\.(js|css)?$ {
    expires 1h;
  }
}

相应的 app.js :

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。
