我曾在一个小型 magento 2 开发团队担任行政职务。对于我即将分享的问题，您可以索取一个演示页面并查看，如果您发现共享的信息不足。所以。
他们已将所有 magento 1 安装设置为 nginx 和 php-fpm7.1
我在调试 Varnish 时遇到了很大的麻烦，因为它需要对标头字段和 Varnish 状态有很深入的了解。
因此他们决定开始使用 magento 2 进行演示，但我们注意到与 magento1（相同堆栈）相比，其性能非常糟糕。使用 magento1.9.2，Nginx 每秒可以处理 3k 个请求，而使用 magento1.9.2 时，每秒处理请求数下降到 50 个。当然，Magento 2.2.1 全页缓存无法正常工作，因此他们要求我按照建议设置 Varnish。
编辑： 标题已更改以反映问题。
这只是关于结帐和管理面板的问题。我错了。问题实际上不仅仅出现在这些地方。问题无处不在，在成功发出请求后几乎一秒钟就会出现。如果我连续 5 次加载登录页面，只有第一次会得到 200，其余时间会得到 502。
设置：
Nginx 在端口 80/443 提供服务，并将所有流量传递到端口 6081（def 端口）的 Varnish。
Varnish 与 Magento 生成的 VCL 一起工作，如果需要的话，重定向到 8080 的后端。
问题： 请参阅上面的编辑。
典型的后端作业，例如缓存刷新和 www.mymagento.com/Checkout/ 会导致 502。每当我尝试将某些东西添加到购物车并去结帐时，我都会收到 502。每当刷新缓存或重新索引数据时，我都会收到 502。
nginx 在事件发生时会报告什么？

问题隐藏在哪里？这是错误的配置还是可能与团队代码有关？我对 Varnish 完全陌生，试图弄清楚这一点让我非常头疼。
编辑：注意到当我以用户身份登录到该页面时，即使我登录/注销，购物车也会被填满。请注意，有一个页面可以让您查看购物车中的商品。即使顶部有一个显示要购买的商品和数量/价格的框，该页面的响应似乎也是“您的购物车是空的”。
笔记：这个问题只有在使用 varnish 之后才会出现。正如我之前所说，使用 Magento 2，服务器每秒最多只能处理约 100 个请求，这实际上是一个糟糕的数字。
非常感谢所有试图提供帮助的人。
