有个需求要分析Nginx日志，也懒得去研究logstach之类的开源工具，干脆直接写一个脚本，自己根据需求来实现：
先看日志格式：我们跟别人的不太一样，所以没办法了：
12.195.166.35 [10/May/2015:14:38:09 +0800] "list.xxxx.com" "GET /new/10:00/9.html?cat=0,0&sort=price_asc HTTP/1.0" 200 42164 "http://list.linuxidc.com/new/10:00/8.html?cat=0,0&sort=price_asc" "Mozilla/5.0 (Linux; U; Android 4.4.2; zh-CN; H60-L02 Build/HDH60-L02) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 UCBrowser/10.4.0.558 U3/0.8.0 Mobile Safari/534.30"
上面是我的日志格式：
脚本如下：
