解析配置阶段最后所说,nginx根据peer的init和data的处理计算。让request有了upstream,upstream有了peer,peer的socketaddr, socketlen有了值,这样nginx可以连接到具体的某台服务器了吧。 本来想针对这块写一大篇篇幅的,但是阅读源码的乐趣在于体会细节,写作一向只是梳理流程,除了这些结构体,其它都是根据这思路写下来,可能...
keeps time spent on receiving the response header from the upstream server (1.7.10); the time is kept in seconds with millisecond resolution. Times of several responses are separated by commas and colons like addresses in the $upstream_addr variable. 接收后端server响应头的时间。 地址 NGINX provi...

作为一个web服务器,我们已经习惯了nginx的类apache日志,即$status。其实nginx的upstream模块下,带有几个变量,却是类squid日志的。他们是: $upstream_addr $upstream_cache_status $upstream_status 当log_format main ‘$msec ‘‘$remote_addr ‘‘$upstream_cache_status/$upstream_status ‘‘$body_bytes_sent ...
