Nginx regularly splits the log

It has been a headache for nginx logs to grow over time, but we can actually send a signal USR1 to the nginx main process to generate new log files, and then archive the old log files. Here is the script I used to split the logs.

[root@master ~] # cat / HomeAccord TestCharger binbinqqinxpostreloadlogfile.shandhelplash Bash # log_pathbase_path='/usr/local/nginx-1.12.1/logs'# get year and monthyear_month=$ (date-d yesterday + "% Y% m") # get yesterdayday=$ (date-d yesterday + "% d") # create backup directorymkdir-p $base_path/$year_month# copy logfile to backupmv $base_path/access.log $base_path/$year_month/access_$day .log # echo $base_path/$year_month/access_$day.log# reload logfilekill-USR1 `cat / usr/local/nginx-1.12.1/logs/ nginx.pid`

Add a scheduled task to crontab and execute the script to split the log at 23:59 every day

# nginx access log backup59 23 * sh / home/ysyf/bin/nginx_reload_logfile.sh

The effect of slicing is as follows, of course, you can also customize the path you like and modify the script.
