做网站的都知道，平常经常要查询下网站PV、UV等网站的访问数据，当然如果网站做了CDN的话，nginx本地的日志就没什么意义了，下面就对nginx网站的日志访问数据做下统计；
概念：
- UV(Unique Visitor)：独立访客，将每个独立上网电脑（以cookie为依据）视为一位访客，一天之内（00:00-24:00），访问您网站的访客数量。一天之内相同cookie的访问只被计算1次
- PV（Page View）：访问量,即页面浏览量或者点击量,用户每次对网站的访问均被记录1次。用户对同一页面的多次访问，访问量值累计
- 统计独立IP：00:00-24:00内相同IP地址只被计算一次,做网站优化的朋友最关心这个
先声明下环境，此次运行的nginx版本1.7，后端Tomcat运行的是动态交互程序（需进行用户认证，如果是静态页面则抓不到cache值，$http_cookie是空值），就是这样；
nginx日志文件配置
http { ???include ??????mime.types; ???default_type ?application/octet-stream; ???log_format ?main ?‘$remote_addr - [$time_local] ?"$request" ‘ ???????????????????????‘ - $status "User_Cookie:$guid" ‘; #User_Cookie为日志显示字符，$guid为变量，具体内容在下面定义，也可在日志格式里写入$http_cookie 显示完整的cookie内容<br> ???sendfile ???????on; ???keepalive_timeout ?65; ???????upstream backserver { ???????ip_hash; ???????server 1.1.2.2:8080; ???????server ?1.1.2.3:8080;}server { ???????listen ??????80; ???????server_name ?localhost; ??????#if ( $http_cookie ~* "(.*)$") ?匹配所有内容 ??????if ( $http_cookie ~* "CSID=([A-Z0-9]*)"){ ???????????????set $guid $1; ???????} ???#只匹配CSID字符信息，此处为正则表达式<br> ???????access_log ?logs/host.access.log ?main; ????????location ~* ^(.*)$ { ????????????#limit_req zone=allips burst=1 nodelay; ??????????????proxy_pass ?http://backserver; ????????????proxy_set_header Host $host; ????????????proxy_set_header X-Real-IP $remote_addr; ????????????proxy_set_header REMOTE-HOST $remote_addr; ????????????proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; ????????????client_max_body_size 8m; ????????????} ???????error_page ??500 502 503 504 ?/50x.html; ???????location = /50x.html { ???????????root ??html; ???????}}注：$http_cookie这个里面的值是一个一个cookie的值，中间以“;”分隔

PV统计可统计单个链接地址访问量：[root@localhost logs]# grep index.shtml host.access.log | wc -l总PV量：[root@localhost logs]# awk ‘{print $6}‘ host.access.log | wc -l独立IP [root@localhost logs]# awk ‘{print $1}‘ host.access.log | sort -r |uniq -c | wc -lUV统计[root@localhost logs]# awk ‘{print $10}‘ host.access.log | sort -r |uniq -c |wc -lCookie 测试页面
关于种cookie，可以使用下面的html代码，编辑，添加需要种的cookie
#index.html <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=gbk"><meta http-equiv="Refresh" content="10"> //为了方便测试，每10秒刷新一次页面</head><body><h1>test.test.com域测试</h1>下面列出了该域的cookie<br><p><script>document.cookie="guid=A1UD8E5512451111111111"; //种cookie，追加document.cookie="city=beijing"; //种cookie，追加document.write(document.cookie); //列出已经存在的</script></p></body></html>
