centos Nginx -收到许多请求时服务器死机

我们有一个大型的Woocommerce网站托管在谷歌VM服务器（E2 4vCPU +16 GB RAM +100 GB SSD存储），最近我们创建了一个使用flutter和WordPress的移动应用程序-Woocommerce-API，但我们面临着三个问题
1.如果两个用户同时打开应用程序，数据加载同步而非并行，似乎服务器在同一时间只能处理单个请求
1.获取数据非常慢，加载产品可能需要5秒以上的高速互联网连接
1.如果用户使用应用程序的网站将需要更多的时间来加载，似乎服务器只处理一个单一的请求在同一时间
环境详细信息

  • 服务器NGINX + MySQL + PHP-FPM
  • PHP 7.4语言
  • 操作系统：Centos 8
  • 所有表格Engin-InnoDB

我们执行了以下操作

  • 将PHP.ini内存限制增加到15GB
  • 将PHP.ini超时限制增加到3000秒
  • 与cloudflare链接的网站。-已安装的缓存插件W3总缓存
  • 将NGINX MAX客户端增加到150

我正在寻找一个关于如何允许服务器/MySQL处理大量请求的建议？
PHP-FPM配置

pm.max_children = 200
pm.start_servers = 50
pm.min_spare_servers = 50
pm.max_spare_servers = 150
;pm.max_requests = 500
;php_admin_value[memory_limit] = 128M
;request_terminate_timeout = 0
;rlimit_core = 0
;rlimit_files = 1024
;pm.process_idle_timeout = 10s;
;pm.max_requests = 500
pm = dynamic
; process.priority = -19

PHP初始化

;user_ini.cache_ttl = 300
implicit_flush = Off
;unserialize_max_depth = 4096
;realpath_cache_size = 4096k
;realpath_cache_ttl = 120
zend.exception_ignore_args = On
max_input_time = 6000
max_execution_time = 3000
;max_input_nesting_level = 64
memory_limit = 15000M
post_max_size = 800M
;mysqlnd.mempool_default_size = 16000
;mysqlnd.net_read_timeout = 31536000
;mysqlnd.net_cmd_buffer_size = 2048
soap.wsdl_cache_enabled=1
soap.wsdl_cache_ttl=86400

首先，确保您的FPM-CONFIG已被实际读取
您已将pm.max_children设置为200，并且memory_limit为15 GB
要有这样的配置，你最好有超过3000 GB的RAM（200 x 15 GB/15000 M）-你没有。
我的建议是-
减少最大内存使用到512 MB php.ini

memory_limit = 512M

fpm配置
将PM设置为按需

pm=ondemand
pm.max_children = 20
pm.start_servers = 4
pm.min_spare_servers = 5
pm.max_spare_servers = 10
pm.process_idle_timeout = 10

进一步调试
将此添加到fpm-config

pm.status_path = /www-status

nginx conf -（您可能需要调整它以适合您的配置）

location ~ ^/(www-status)$ {
                fastcgi_pass 127.0.0.1:9000; # replace this or use the unix socket
                fastcgi_param SCRIPT_FILENAME 
                $document_root$fastcgi_script_name;
                fastcgi_param SCRIPT_NAME $fastcgi_script_name;
                fastcgi_index index.php;
                include fastcgi_params;
        }

进入site.com/www-status，你会看到fpm的使用信息，通过这个你可以知道你实际需要多少。
我也尝试使用Nginx缓存，这将是一个巨大的帮助您的服务器使用NGINX缓存-https://docs.nginx.com/nginx/admin-guide/content-cache/content-caching
