1、rlimit介绍在Linux系统中，Resoucelimit指在一个进程的执行过程中，它所能得到的资源的限制，比如进程的corefile的最大值，虚拟内存的最大值等。 

在做Nginx高压力测试时，偶尔某台WEB的logs抛出TooManyOpenFiles，一般从以下3方面调优：第一：nginx.conf参数规划与设置worker_rlimit_nofile：限制单个工作进程打开的最大文件数

1userwww-data;2pid/var/run/nginx.pid;3worker_processesauto;4worker_rlimit_nofile100000; user和pid应该按默认设置

logs/nginx_error.log    crit; pid                /usr/local/nginx/logs/nginx.pid;//nginx进程id worker_rlimit_nofile

linux使用structrlimit结构体来实现的，rlimit是resourcelimit的缩写。
