详解NGINX如何统计网站的PV、UV、独立IP

Nginx: PV、UV、独立IP

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

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：

1	[root@localhost logs]# grep index.shtml host.access.log | wc -l

总PV量：

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

独立IP

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

UV统计

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