我对subj有一些错误.服务器没有高负载:~15%的CPU,有几个Gb的内存,硬盘不是buisy.但是错误502大约在3%的情况下抛出.
程序:Debian 6,nginx/0.7.62,php5-fpm(5.3.3-1).
在nginx的error.log中是这个错误:
connect() to unix:/var/run/php5-fpm.sock failed

php5-fpm的状态通常是这样的:
accepted conn: 41680
pool: www
process manager: dynamic
idle processes: 258
active processes: 1
total processes: 259

我认为,这意味着负载不高.
我增加了积压参数:在sysctl中 - net.core.somaxconn = 5000,在php-fpm池中 - listen.backlog = 5000.没有效果.
我引用一个配置:
/etc/nginx/nginx.conf
user www-data;
worker_processes 8;
timer_resolution 100ms;
worker_rlimit_nofile 20240;
worker_priority -5;
