Shell script splits Nginx logs and cleans them regularly [without restarting nginx]

I wrote an article about shell script splitting Nginx logs and cleaning them regularly, link: http://www.webyang.net/Html/web/article_255.html but need to reload nginx, some people have a psychological shadow on restarting nginx , so I changed it again:

 

1. #!/bin/bash
2. #nginx access log segmentation shell script
3. #log directory
4. log_dir="/usr/local/nginx/logs/"
5. cd $ log_dir
6. time=`date +%Y%m%d --date="-1 day"`
7. #Hisashi preservation heaven number
8. save_days=15
9. #The position of the log file name is divided by '/', key('/' number + 1)
10. num = 6 ;
11.  
12. #To be optimized here (get the file name without a suffix)
13. website=`ls $log_dir*.log | xargs -n 1 | cut -f 1 -d "." | cut -f $num -d "/"`
14. #All log files in the log directory are folders, and the corresponding time files will be created cyclically
15. for i in $website
16. do
17. #Check if the directory exists
18. if[!-d $log_dir$i ];then
19. mkdir "$i"
20. be
21.  
22. cp $log_dir$i.log $log_dir$i/$i-$time.log
23. true>$log_dir$i.log
24. done
25.  
26. find $log_dir -mtime +$save_days -exec rm -rf {} \;

Set up crontab to run once every morning.

展示: web1.log => web1/web1-20160322.log web1/web1-20160323.log web2.log => web2/web2-20160322.log web2/web2-20160323.log

 

There are other methods such as cronolog, logrotate, etc., you can refer to: http://www.tuicool.com/articles/BF36rq
