间歇性的nginx超时将jetty作为上游服务器

Question

我们确实有一个奇怪的nginx超时生产问题.超时说明如下:

"upstream timed out(110: Connection timed out)" 

这里,上游服务器正在jetty运行nginx的同一主机上运行.Jetty正在运行8080nginx的端口上运行443.

检查了上述错误后,我验证了jetty日志和nginx日志的日志.虽然jetty在不到一秒的时间内就会返回响应,但是发送给nginx的响应正在delayed接近60 secs.并且nginx正在使用http响应代码在60秒后触发timedout警报504.这种情况正在发生intermittently.

以下是jetty和nginx的日志,用于超时请求.

从上面的两个日志中,我们可以推断出码头返回了200响应2017-05-11T16:17:06.927Z,但它是由nginx收到的2017-05-11T17:18:09+01:00.这60多秒导致超时.它有点奇怪,因为nginx和jetty都托管在同一台主机上.

如果有人可以帮助我们调试问题或提供建议,那就太棒了.

提前谢谢了.

您需要进行设置proxy_http_version以使您的保活设置相关。此外，该keepalive设置应该位于您的上游块中。

例如将其添加到您的配置中

proxy_http_version 1.1;
proxy_set_header Connection "";
