我的php-fpm-pool-settings在下面，我相信这个正在产生错误，可能是我错了
listen.backlog = 65535 ;[php-fpm-pool-settings] pm = dynamic pm.max_children = 5000 pm.start_servers = 50 pm.min_spare_servers = 20 pm.max_spare_servers = 70 pm.max_requests = 2000
我的nginx conf在下面
user nginx; worker_processes 8; # number of file descriptors used for nginx # the limit for the maximum FDs on the server is usually set by the OS. # if you don't set FD's then OS settings will be used which is by default 2000 worker_rlimit_nofile 99999; error_log /var/log/nginx/error.log crit; include /etc/nginx/modules.conf.d/*.conf; events { worker_connections 16192; use epoll; multi_accept on; } http { include mime.types; default_type application/octet-stream; open_file_cache max=2048 inactive=20s; open_file_cache_valid 30s; open_file_cache_min_uses 5; open_file_cache_errors off; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_requests 100000; reset_timedout_connection on; client_body_timeout 30; send_timeout 15; client_header_timeout 12; proxy_connect_timeout 600s; proxy_send_timeout 600s; proxy_read_timeout 600s; fastcgi_buffers 8 128k; fastcgi_buffer_size 256k; fastcgi_send_timeout 600s; fastcgi_read_timeout 600s; types_hash_max_size 2048; gzip on; gzip_min_length 1000; gzip_proxied expired no-cache no-store private auth; gzip_types application/x-javascript text/css application/javascript text/javascript text/plain text/xml application/json application/v$ gzip_disable "MSIE [1-6]\.(?!.*SV1)"; server_tokens off; include /etc/nginx/conf.d/*.conf; }
