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，$http_cookie是空值），就是这样；
nginx日志文件配置
http {
include mime.types;
default_type application/octet-stream;
log_format main '$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=a1ud8e5512412451111111111"; //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>
