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 pm2VPS云主机
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 $proxy_add_x_forwarded_for; proxy_set_header Host KaTeX parse error: Expected 'EOF', got '}' at position 107: …http://nodejs; }̲ location ~ .*\… { expires 30d; } location ~ ..(js|css)?$ { 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。
