本文主要使用的是grep,awk,cut等工具来对nginx日志进行统计和分析，具体如下：


1，列出当天访问最多次数的ip地址

cut -d- -f 1 /usr/local/nginx/logs/20160329/access_2016032913.log |uniq -c | sort -rn | head -20

2，查看某一个页面被访问的次数

[root@httpservera 20160329]#grep "/index.php" log_file | wc -l


3，查看每一个IP访问了多少页面并排序

awk '{++S[$1]} END {for (a in S) print a,S[a]}' access_2016032913.log |uniq|sort -rn|more

223.64.237.37 187
223.64.209.247 2
223.64.158.4 15

其中，sort -rn 按照数字从大到小排序，uniq 将重复行去除。


4，查看某一个ip访问了那些页面：grep ^xx.xx.xx.xx log_file |awk '{print $1,$7}'

access_2016032913.log:223.147.39.194 //remind/redDot/checkRedDot.json

5,去掉搜索引擎统计当天的页面：awk '{print $12,$1}' access_2016032913.log | grep ^\"Mozilla | awk '{print $2}' |sort | uniq | wc -l

[root@httpservera 20160329]# awk '{print $12,$1}' access_2016032913.log | grep ^\"Mozilla | awk '{print $2}' |sort | uniq | wc -l      
35


6，查看一个小时内有多少ip访问：

1
2
[root@httpservera 20160329]# awk '{print $4,$1}' access_2016032913.log | grep 29/Mar/2016:13 | awk '{print $2}'| sort | uniq | wc -l   
1926


2.访问量统计


1.根据访问IP统计UV

awk '{print $1}'  access.log|sort | uniq -c |wc -l


2.统计访问URL统计PV

awk '{print $7}' access.log|wc -l


3.查询访问最频繁的URL

awk '{print $7}' access.log|sort | uniq -c |sort -n -k 1 -r|more


4.查询访问最频繁的IP

awk '{print $1}' access.log|sort | uniq -c |sort -n -k 1 -r|more


5.根据时间段统计查看日志

 cat  access.log| sed -n '/14\/Mar\/2015:21/,/14\/Mar\/2015:22/p'|more
