  • nginx 的 upstream timed out 问题

    nginx 作为负载服务,表现为网站访问很慢,有些文件或页面要等待到60s才会返回,我注意到60s就是超时时间,但是超时后返回状态是正常值200,网站可以正常打开,就是会一直等待到超时才打开,而且问题出现不定时,不定文件,静态文件也会出现这个问题。貌似很奇葩是吧,最终查看错误信息没有注意到 IPv6,导致饶了不少弯。

    错误信息:

    [error] 5292#5912: *3059 upstream timed out (10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond) while connecting to upstream, client: 66.249.69.219, server: xxx.com, request: "GET /shop/view.jhtml HTTP/1.1", upstream: "http://[::1]:12002/shop/view.jhtml", host: "www.xxx.com"

    配置如下:

        upstream zcun_pool {
            server localhost:12001 max_fails=1 fail_timeout=30s;
            server localhost:12002 max_fails=1 fail_timeout=30s;
            server localhost:12003 max_fails=1 fail_timeout=30s;
        }

    发现可能是 IPv6 的问题后,改 localhost 为本地 IPv4 即可解决.....这错误说起来还真是低级~

        upstream zcun_pool {
            server 127.0.0.1:12001 max_fails=1 fail_timeout=30s;
            server 127.0.0.1:12002 max_fails=1 fail_timeout=30s;
            server 127.0.0.1:12003 max_fails=1 fail_timeout=30s;
        }

    网站访问回复正常。
