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（页面浏览量）是指用户每次访问网站时所产生的点击量或页面浏览量，记录为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 &#39;$remote_addr - [$time_local] "$request" &#39;
            &#39; - $status "user_cookie:$guid" &#39;;
 #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

Copy after login

总pv量：

[root@localhost logs]# awk &#39;{print $6}&#39; host.access.log | wc -l

Copy after login

独立ip

[root@localhost logs]# awk &#39;{print $1}&#39; host.access.log | sort -r |uniq -c | wc -l

Copy after login

uv统计

[root@localhost logs]# awk &#39;{print $10}&#39; host.access.log | sort -r |uniq -c |wc -l

Copy after login

cookie 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>
