Nginx Too many open files 问题

之前晚上直播出现 Too many open files, 很多接口 access_log 出现500报错

查了下资料,更改步骤如下:

/etc/sysctl.conf
	fs.file-max = 70000 (这个数值应当大于等于下面的硬限制)

/etc/security/limits.conf
	nginx       soft    nofile  10000
	nginx       hard    nofile  30000

让上面的配置生效
	sysctl -p

设置nginx应用层面的限制
vim /etc/nginx/nginx.conf
	
	# set open fd limit to 30000
	worker_rlimit_nofile 30000;

测试:

ab -r -k -n200 -c30 -H "User-Agent: Test By George" "http://api.ltwen.com/test/ab"
