概念：
-
uv(unique visitor)：獨(dú)立訪客，將每個(gè)獨(dú)立上網(wǎng)電腦（以cookie為依據(jù)）視為一位訪客，一天之內(nèi)（00:00-24:00），訪問您網(wǎng)站的訪客數(shù)量。一天之內(nèi)相同cookie的訪問只被計(jì)算1次
-
PV（頁(yè)面瀏覽量）是指用戶每次訪問網(wǎng)站時(shí)所產(chǎn)生的點(diǎn)擊量或頁(yè)面瀏覽量，記錄為1次。用戶對(duì)同一頁(yè)面的多次訪問，訪問量值累計(jì)
-
統(tǒng)計(jì)獨(dú)立ip：00:00-24:00內(nèi)相同ip地址只被計(jì)算一次,做網(wǎng)站優(yōu)化的朋友最關(guān)心這個(gè)
先聲明下環(huán)境，此次運(yùn)行的nginx版本1.7，后端tomcat運(yùn)行的是動(dòng)態(tài)交互程序（需進(jìn)行用戶認(rèn)證，如果是靜態(tài)頁(yè)面則抓不到cache值，$http_cookie是空值），就是這樣；
nginx日志文件配置
http?{ ??include????mime.types; ??default_type?application/octet-stream; ??log_format?main?'$remote_addr?-?[$time_local]?"$request"?' ????????????'?-?$status?"user_cookie:$guid"?'; ?#user_cookie為日志顯示字符，$guid為變量，具體內(nèi)容在下面定義，也可在日志格式里寫入$http_cookie?顯示完整的cookie內(nèi)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?(?$http_cookie?~*?"(.*)$")?匹配所有內(nèi)容 ????if?(?$http_cookie?~*?"csid=([a-z0-9]*)"){ ????????set?$guid?$1; ????}??#只匹配csid字符信息，此處為正則表達(dá)式<br> ????access_log?logs/host.access.log?main; ?????location?~*?^(.*)$?{ ???????#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這個(gè)里面的值是一個(gè)一個(gè)cookie的值，中間以“;”分隔
