Logrotate is a log-cutting tool for most Linux systems, with a configuration file of/etc/logrotate.conf that simply defines an instance of the Apache log cut:

Vim/etc/logrotate.d/apache

How many logs can rotate keep

Notifempty if it's an empty file, don't dump it.

Daily Daily Dump

Missingok if the specified directory does not exist, Logrotate will error, which is used to close the error

A size file is dumped at 50M

Sharedscripts All log files are rotated once the script is executed uniformly

Postrotate/endscript: Commands that need to be executed after the dump can be placed in this pair, these two keywords must be taken separately

Delaycompress: When used with compress, the dump log file is compressed until the next dump

-f/var/run/nginx/nginx.pid confirm that Nginx is started

KILL-USR1 ' Cat/var/run/nginx/nginx.pid ' is not a process that aborts nginx, but is passed to it to generate a signal to regenerate the log
