LogRotate

Add a service to logrotate

vi /etc/logrotate.d/name_of_file

/var/log/some_dir/somelog.log {
        su root root
        missingok
        notifempty
        compress
        size 5M
        daily
        create 0600 root root
}

• su - run a root user
• missingok - do not output error if logfile is missing
• notifempty - donot rotate log file if it is empty
• compress - Old versions of log files are compressed with gzip(1) by default
• size - Log file is rotated only if it grow bigger than 20k
• daily - ensures daily rotation
• create - creates a new log file wit permissions 600 where owner and group is root user

Force run a logrotate

logrotate -f /etc/logrotate.conf

Once it's all done no need to do anything else, log rotate already runs in /etc/cron.daily/logrotate
