[WARNING] fpm_children_bury()

最近接手nginx+php的WEB环境维护，发现PHP-cgiCPU很好，也造成负载很高，于是在网上找了些资料，并且针对自己的错误，将问题收集再次，并且网上还给了解决方案，所以放在这里留作以后查询

以上是php日志的警告信息

解决方法

1、提升服务器的文件句柄打开打开[/b]
/etc/security/limits.conf : (增加)
* soft nofile 51200
* hard nofile 51200
# vi /etc/security/limits.conf 加上

* soft nofile 51200

* hard nofile 51200

2、提升nginx的进程文件打开数[/b]

nginx.conf : worker_rlimit_nofile 51200;

3、修改php-fpm.conf文件，主要需要修改2处[/b]。

命令 ulimit -n 查看限制的打开文件数，php-fpm.conf 中的选项rlimit_files 确保和此数值一致。

<value name="max_requests">10240</value>

<value name="rlimit_files">51200</value>

4、修改系统内核
# vi /etc/sysctl.conf

底部添加

fs.file-max=51200

到此结束.
