    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 -gln -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 savepm2 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/*.confupstream 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。
