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,并且没有响应,出现5 **超时错误。 在AWS Elastic Beanstalks Nginx日志中,我发现了此错误消息:
[警告] 18037#0:1024个worker_connections不够
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。
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。

Nginx worker_connections的默认值为1024,这对于您来说还不够。
在nginx.conf中的http前面添加事件块,因此看起来像这样:
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
