In linux, Shell scripts split Nginx logs and regularly clean up examples

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,
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
