由于即将举办活动，我们预计在几周内，运行在 Ubuntu、NGINX 和 PHP7.1-fpm 上的 Magento2 电子商务网站上的流量会很高（大约 2000 个同时用户）。由于我们的目录很大，我们将 Digitalocean droplet 升级到最高规格，即 192 GB 内存和 32 个 vCPU。
该网站的运行速度非常快，但是，一旦达到 800 个用户，它就会开始变得非常慢，一段时间后，它最终会显示 502 Bad Gateway 错误，在这种临时事件期间我们确实无法承受这种错误。
我们最近的错误现在与 pm.start_servers 或 pm.min/max_spare_servers 有关，它们是：
[16-Mar-2020 21:50:35] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 8 children, there are 0 idle$
[16-Mar-2020 21:50:36] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 16 children, there are 0 idl$
我们尝试了几种设置，但似乎都无法可靠地工作。以下是几种设置：
/etc/php/7.1/fpm/pool.d/www.conf：
pm = dynamic
pm.start_servers = 20
pm.min_spare_servers = 20
pm.max_spare_servers = 50
;pm.process_idle_timeout = 10s;
pm.max_requests = 0
所以现在我们正在寻找解决方案或方法来精确计算这些值？还有其他注意事项或设置需要我们更改吗？

非常感谢一些专家的帮助，谢谢

运行以下命令并尝试根据 www.conf 中的结果设置值
ps --no-headers -o "rss,cmd" -C php-fpm7.3 | awk '{ sum+=$1 } END { printf ("%d%s\n", sum/NR/1024,"Mb") }'
计算值
min_spare_servers + (max_spare_servers - min_spare_servers) / 2
例子
pm.max_children = 120
pm.start_servers = 45
pm.min_spare_servers = 10
pm.max_spare_servers = 80
pm.max_requests = 500

与您的问题无关，但请记住，在 2020 年 3 月，PHP 7.1 根本没有维护，并且包含永远不会修补的漏洞。其中一些漏洞允许黑客控制您的 Web 服务器...
