网上搜了下说是系统最大文件数和php-fpm.conf中rlimit_files不匹配的原因

一、我的配置
centos5.2 64bit
nginx0.7.61+php5.2.10+php-5.2.10-fpm-0.5.13

/etc/rc.local

ulimit -Shn 51200

/opt/nginx/etc/nginx.conf

worker_rlimit_nofile 51200;
events
{
use epoll;

worker_connections 51200;
}

/opt/php/etc/php-fpm.conf

51200

ulimit -n

1024

cat /proc/sys/fs/file-max

765985

cat /proc/sys/fs/file-nr

3060 0 765985

二、修改
1.
/etc/security/limits.conf
文件尾部增加

* soft nofile 51200
* hard nofile 51200

设置为星号代表全局
这个当中的硬限制是实际的限制，而软限制，是warnning限制，只会做出warning。

2.
退出控制台重新登录

ulimit -n

51200

3.
php-fpm reload不会生效，所以用 php-fpm restart

4.
检查一下
tail /opt/php/logs/php-fpm.log
ok,收工
