什么会减慢我的系统nginx、php和fpm？

9使用nginx和php fpm

在这一天之前，一切都很顺利。请注意，这非常非常缓慢，与php有关的一切

有时我会出错

“504 Gateway Time-Out”

我想知道是否有一种方法可以进行扫描，这就是造成这种情况的原因

多谢各位

我已经完成了以下操作：操作缓存设置：

opcache.enable=1
opcache.enable_cli=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1

Nginx如下所示：

    worker_processes  6;

    events {
        worker_connections  8096;
        multi_accept        on;
        use                 kqueue;
    }
    worker_rlimit_nofile 40000;
http {
.....
      proxy_connect_timeout       600;
      proxy_send_timeout          600;
      proxy_read_timeout          600;
      send_timeout                600;
    client_body_buffer_size 10K;
    client_header_buffer_size 1k;
    client_max_body_size 8m;
    large_client_header_buffers 2 1k;

    gzip  on;
    gzip_comp_level  2;
    gzip_min_length  1000;
    gzip_proxied     expired no-cache no-store private auth;
    gzip_types       text/plain application/x-javascript text/xml text/css application/xml;
    server_tokens off;
......
}

php fpm如下所示：

pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
request_terminate_timeout = 30s
request_slowlog_timeout = 10s
slowlog = /var/log/php-fpm/default/slow.log
php_admin_flag[log_errors] = on

max_execution_time = 300
request_terminate_timeout = 300

php.ini是这样的：

pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
request_terminate_timeout = 30s
request_slowlog_timeout = 10s
slowlog = /var/log/php-fpm/default/slow.log
php_admin_flag[log_errors] = on

max_execution_time = 300
request_terminate_timeout = 300

谢谢大家

您是否尝试重新启动或重置？如果你跑了怎么说？
