If you have a lot of static files to serve through Nginx then caching of the files' metadata (not the actual files' contents) can save some latency.# open_file_cache max=65535 inactive=20s; open_file_cache_valid 30s; open_file_cache_min_uses 2; open_file_cache_errors on;

服务器的配置 CPU: Intel Xeon E5-2650*2 硬盘: 525GB SSD 内存: 64GB DDR3 ECC#

PHP 线程：12000+的时候就挂了#

服务器就 504 gateway time-out#

求大神给个解决方法！ TAT 很难过。

只能说你的服务器配置好奢华。。。

[Mask0c]

@lzghades 有没有什么解决的办法？

[krisbai]

worker_processes auto; 不配置下？
