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。
