Nginx Upstream timed out (110: Connection timed out)

Nginx Upstream timed out (110: Connection timed out) – 运维生存时间 http://www.ttlsa.com/nginx/nginx-upstream-timed-out-110-connection-timed-out/

在Nginx错误日志中，有大量的下列信息：

Upstream timed out (110: Connection timed out) while reading response header from upstream

这种情况主要在厦门两种情况下发生:

1. nginx proxy

需要适当的调整proxy_read_timeout值。

 

1 2 3 4 5

location / {         ...         proxy_read_timeout 150;         ...     }

2. Nginx作为php-fpm等等其他的有上游服务

【php-fpm作为nginx的upstream  php-fpm作为nginx的上游服务】

在这种情况下，适当的调整fastcgi_read_timeout选项值

Module ngx_http_core_module https://nginx.org/en/docs/http/ngx_http_core_module.html#keepalive_timeout

Syntax:	keepalive_timeout timeout [header_timeout];
Default:	keepalive_timeout 75s;
Context:	http, server, location

The first parameter sets a timeout during which a keep-alive client connection will stay open on the server side. The zero value disables keep-alive client connections. The optional second parameter sets a value in the “Keep-Alive: timeout=time” response header field. Two parameters may differ.

The “Keep-Alive: timeout=time” header field is recognized by Mozilla and Konqueror. MSIE closes keep-alive connections by itself in about 60 seconds.
