[shell]Nginx/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" | 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
<pre>
接着从日志里查看该ip在干嘛:
<pre lang="php">
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" www20060723.log | awk '{print $2}' | sort | uniq -c| sort -nr | wc -l
　　==============================nginx
　　log_format main '[$time_local] $remote_addr $status $request_time $body_bytes_sent "$request" "$http_referer"';
access_log      /data0/logs/access.log  main;
　　格式如下：
58.60.188.61 200 0.265 28 "POST /event/time HTTP/1.1" "http://host/loupan/207846/feature"
　　
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
38 112.97.192.16
     20 117.136.31.145
     19 112.97.192.31
      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
　　找出访问次数最多的10个IP
awk '{print $3}' access.log |sort |uniq -c|sort -nr|head
  10680 10.0.21.17
   1702 10.0.20.167
    823 10.0.20.51
    504 10.0.20.255
    215 58.60.188.61
    192 183.17.161.216
     38 112.97.192.16
     20 117.136.31.145
     19 112.97.192.31
      6 113.106.88.10
　　找出某天访问次数最多的10个IP
　　cat /tmp/access.log | grep "20/Mar/2011" |awk '{print $3}'|sort |uniq -c|sort -nr|head
     38 112.97.192.16
     20 117.136.31.145
     19 112.97.192.31
      3 61.156.31.20
      2 209.213.40.6
      1 222.76.85.28
　　
当天ip连接数最高的ip都在干些什么:
cat access.log | grep "10.0.21.17" | awk '{print $8}' | sort | uniq -c | sort -nr | head -n 10

找出访问次数最多的几个分钟
 awk '{print $1}' access.log | grep "20/Mar/2011" |cut -c 14-18|sort|uniq -c|sort -nr|head
