The Shell script separates Nginx logs and regularly cleans them.

: This article mainly introduces how to split Nginx logs using Shell scripts and regularly clean up Nginx logs. For more information about PHP tutorials, see. By default, nginx generates only one access log. during daily accumulation, the log file will become very large. if you need to analyze the log, whether it is using script analysis, it is not convenient to download logs for local analysis. Splitting Nginx access logs every day facilitates log analysis.

I. create a script file

Vim cut_nginx_log.sh

 
 

  
  
#! /Bin/bash
  
  
# Nginx access log segmentation shell script
  
  
# Www.webyang.net
  
  
# Log Directory
  
  
Log_dir = "/usr/local/nginx/logs /"
  
  
Cd $ log_dir
  
  
Time = 'date + % Y % m % d -- date = "-1 day "'
  
  
# Nginx Startup directory
  
  
Nginx_dir = "/etc/init. d/nginx"
  
  
# Log Retention days
  
  
Save_days = 15
  
  
# Location where the log file name is located '/', key (number of '/' + 1)
  
  
Num = 6;
  
  
 
  
  
# Here to be optimized (get the file name without a suffix)
  
  
Website = 'ls $ log_dir *. log | xargs-n 1 | cut-f 1-d "." | cut-f $ num-d "/"'
  
  
# All log files in the log directory are folders, and corresponding time files are created cyclically.
  
  
For I in $ website
  
  
Do
  
  
# Determine whether a directory exists
  
  
If [! -D $ log_dir $ I]; then
  
  
Mkdir "$ I"
  
  
Fi
  
  
Mv $ log_dir $ I. log $ log_dir $ I/$ I-$ time. log
  
  
Done
  
  
 
  
  
# Delete data before the specified number of days
  
  
Find $ log_dir/-mtime + $ save_days-exec rm-rf {}\;
  
  
 
  
  
# Enable nginx smoothly
  
  
$ Nginx_dir reload
 
 

2. set crontab and cut regularly every day
If not, run yum-y install crontabs.
Enter the crontab-e command (for details, refer to: http://www.webyang.net/Html/web/article_232.html ),
Enter the following content:
00 00 ***/bin/bash/usr/local/nginx/cut_nginx_log.sh
1. 00 means 00: 00, that is, A.M.. you do not need to define "***" as "day, month, and year ".
2. "/usr/local/nginx/cut_nginx_log.sh" is your shell path.

OK! At every day, the log is automatically cut and stored in a directory named after the website log file.

Web1.log => web1/web1-20160322.log web1/web1-20160323.log
Web2.log => web2/web2-20160322.log web2/web2-20160323.log
