用Nginx*Node.js

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!
`
  next()
}, (req, res) => {
  res.send(`
  ${hi}
  ${req.method}

  ${req.originalUrl}

  ${req.query.id}

  `)
})

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。
