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。
