Shell script splits Nginx logs and cleans up regularly

The default nginx will only generate an access log, in the accumulation of daily, log files will become very large, if you need to do a log analysis, whether it is using script analysis, or the log download local analysis, is not very convenient. The daily partition of Nginx access logs facilitates the analysis of logs.

A: Create a new script file

Vim cut_nginx_log.sh

 
 

  
  

  
#!/bin/bash
  
  

  
#nginx Access Log Segmentation shell script
  
  

  
#www. webyang.net
  
  

  
#日志目录
  
  

  
Log_dir = "/usr/local/nginx/logs/"
  
  

  
CD $log _dir
  
  

  
 Time = ' Date +%y%m%d--date= '-1 Day '
  
  

  
#nginx启动目录
  
  

  
Nginx_dir = "/etc/init.d/nginx"
  
  

  
#日志保存天数
  
  

  
save_days =  the
  
  

  
#日志文件名所处 '/' Split position, key ('/' number +1)
  
  

  
Num = 6 ;
  
  

  

  
  

  
#此处待优化 (get file name without suffix)
  
  

  
website = ' ls $log _dir*.log | xargs-n 1 | cut-f 1-d "." | cut-f $num-D "/" '
  
  

  
#日志目录下所有的日志文件为文件夹, cycle the new time file
  
  

  
 for I inch $website
  
  

  
Do
  
  

  
#判断目录是否存在
  
  

  
if [! - d $log _dir$i ];  Then
  
  

  
mkdir "$i"
  
  

  
Fi
  
  

  
MV $log _dir$i . Log $log _dir$i / $i - $time . Log
  
  

  
Done
  
  

  

  
  

  
#删除设置天数前的数据
  
  

  
Find $log _dir / - Mtime + $save _days - exec RM - RF {} \;
  
  

  

  
  

  
#平滑启动nginx
  
  

  
$nginx _dir Reload
 
 

Second, set crontab, daily cutting
If it is not installed, run the Yum-y install Crontabs installation.
Enter the CRONTAB-E command (detail reference: http://www.webyang.net/Html/web/article_232.html),
Enter the following content:
XX * * * */bin/bash/usr/local/nginx/cut_nginx_log.sh
1, 00 00 means 00 Points 00 points, that is, 0 o'clock in the morning, the back "* * *" for "Sun and Moon Year" does not need to define
2. "/usr/local/nginx/cut_nginx_log.sh" is the path of your shell.

Ok! When you're done, the log is automatically cut at 0 o'clock every day and the corresponding directory is named after the site log file.

Third, display
Web1.log = Web1/web1-20160322.log web1/web1-20160323.log
Web2.log = Web2/web2-20160322.log web2/web2-20160323.log

The above describes the shell script to split the Nginx log, and regularly clean up, including the content, I hope that the PHP tutorial interested in a friend helpful.
