nginx与apacherizhi/ target=_blank class=infotextkey>apache日志分析脚本。
1,查看apache进程:
ps aux | grep httpd | grep -v grep | wc -l
2,查看80端口的tcp连接:
netstat -tan | grep "ESTABLISHED" | grep ":80" | wc -l
3,通过日志查看当天ip连接数，过滤重复:
cat access_log | grep "20/Oct/2008" |
linuxjishu/13830.html target=_blank class=infotextkey>awk '{print $2}' | sort | uniq -c | sort -nr
4,当天ip连接数最高的ip都在干些什么(原来是蜘蛛):
cat access_log | grep "20/Oct/2008:00" | grep "122.102.7.212" | awk '{print $8}' | sort | uniq -c | sort -nr | head -n 10
5,当天访问页面排前10的url:
cat access_log | grep "20/Oct/2008:00" | awk '{print $8}' | sort | uniq -c | sort -nr | head -n 10
6,用tcpdump嗅探80端口的访问看看谁最高
tcpdump -i
eth0 -tnn dst port 80 -c 1000 | awk -F"." '{print $1"."$2"."$3"."$4}' | sort | uniq -c | sort -nr
接着从日志里查看该ip在干嘛:
cat access_log | grep 122.102.7.212| awk '{print $1"t"$8}' | sort | uniq -c | sort -nr | less
7,查看某一时间段的ip连接数:
grep "2006:0[7-8]" www20060723.log | awk '{print $2}' | sort | uniq -c| sort -nr | wc -l

格式如下：

通过日志查看当天ip连接数，过滤重复
cat access.log | grep "20/Mar/2011" | awk '{print $3}' | sort | uniq -c | sort -nr

3 61.156.31.20
2 209.213.40.6
1 222.76.85.28
当天访问页面排前10的url:
cat access.log | grep "20/Mar/2011" | awk '{print $8}' | sort | uniq -c | sort -nr | head -n 10
