node.js – 哪个最有效：通过nginx或节点通过nginx反向代理直接

它通常是最优化的解决方案,可以减少node.js服务器上的请求数量,该服务器对服务器静态文件的速度比nginx慢,例如：

如果您已经为nodejs app设置了反向代理,那么实现这一目标的配置非常简单.

nd nginx配置可能是

   root /home/myapp;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    server_name _;

    location /public/ {
            alias /home/myapp/public/;
    }

    location / {
            proxy_pass http://IPADRESSOFNODEJSSERVER:8080;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
            # First attempt to serve request as file,then
            # as directory,then fall back to displaying a 404.
            #try_files $uri $uri/ =404;
    }

每个请求/ public /在url的第一部分都将由nginx处理,其他所有请求都将代理到你的IP地址：IPADRESSOFNODEJSSERVER：nODEJSPORT通常IPADRESSOFNODEJSSERVER是localhost

快递的doc部分告诉http://expressjs.com/en/advanced/best-practice-performance.html#proxy

An even better option is to use a reverse proxy to serve static files;
see Use a reverse proxy for more information.

此外,nginx将允许您轻松定义缓存规则,因此对于不更改它的静态资产,也可以使用一行加速您的应用程序.

location /public/ {
            expires 10d;
            alias /home/myapp/public/;
        }
