我正在使用ROR + Nginx +乘客和亚马逊网络服务开发Android服务。
服务器运行良好,但昨天服务器突然被击落。
我试图解决这个问题,但我无法解决。
这是我的问题。
首先,EC2实例的log / production.log不会写任何日志。 我可以在我的Android应用程序日志中收到502错误的网关错误消息。
其次,包括http,https在内的所有请求都由502 badgateway响应。
第三,我的AWS负载均衡器记录了50X错误。
我想这个问题与ELB有关,但我不知道如何解决。
我有ssl证书,而且我只有一个EC2实例。
任何帮助将不胜感激。

答案 0 :(得分:0)
如果你看到你添加的日志,它说&#34;请求队列已满&#34;,基本上你有一些长时间运行的api,因为队列之后被抛出了50x充分。
重新启动nginx可能暂时解决了这个问题,但是你需要查看你的api的响应时间,看看哪些性能很慢并修复它们,否则它将是一个反复出现的问题,你必须每天重启nginx。
