Nginx错误"1024个worker_connections不够". [英] Nginx error "1024 worker_connections are not enough"
问题描述
我的网站正在使用带有反向代理的Nginx在Docker映像中运行. 站点在繁忙的流量下可以正常工作多个小时,但最终它会停止工作,并且没有任何响应,并显示5 **超时错误. 在AWS Elastic Beanstalks Nginx日志中,我发现了此错误消息:
My website is running in a Docker Image using Nginx with reverse proxy. Site is working prefectly for many hours under heavy traffic, but eventually it stops working and giving no response with 5** time out error. In AWS Elastic Beanstalks Nginx-log I found this error-message:
[警告] 18037#0:1024个worker_connections不够
[alert] 18037#0: 1024 worker_connections are not enough
恐怕我的自定义Nginx配置有问题, 但是我不明白那是什么. 随附来自https-redirect-docker-sc.config的代码.
I am afraid something is wrong with my custom Nginx-config, but I do not understand what it is. Code from https-redirect-docker-sc.config is attached.
我试图调试代码以查找任何内存泄漏或循环,但找不到任何解决方案.
I have tried to debug code to find any memory leaks or loops, but I can not find any solution.

推荐答案
Nginx worker_connections的默认值为1024,这对于您来说还不够.
Default value for Nginx worker_connections is 1024, which is not enough for you.
在nginx.conf中的http前面添加事件块,因此看起来像这样:
Add events block before http in your nginx.conf, so it looks like this:
events {
worker_connections 4096; ## Default: 1024
}
http {
include conf/mime.types;
.....
}
您还可以增加worker_processes的数量(默认= 1),因此服务器可以处理的连接总数为worker_processes * worker_connections
You can also increase number of worker_processes(default = 1), so the total amount of connections your server can handle would be worker_processes * worker_connections
