Logrotate Example for Custom Logs

By | March 25, 2016

You will need this if you are using custom location for log files.

Below is example for Nginx where log files are directly created in /var/www/example.com/logs

You can put following in /etc/logrotate.d/nginx

/var/www/example.com/logs/*.log {
        daily
        missingok
        rotate 52
        compress
        delaycompress
        notifempty
        create 0640 www-data adm
        sharedscripts
        prerotate
                if [ -d /etc/logrotate.d/httpd-prerotate ]; then \
                        run-parts /etc/logrotate.d/httpd-prerotate; \
                fi; \
        endscript
        postrotate
                [ ! -f /var/run/nginx.pid ] || kill -USR1 `cat /var/run/nginx.pid`
        endscript
}

Verify

Its always better to verify if logrotate script is correct.

Just run command

logrotate -d

It will produce debug output.

Restart/Force Update

Remember, logrotate is not service which can be restarted. In case you need your logrotate script to run immediately, use:

logrotate -f -v /etc/logrotate.d/nginx

Rotating log is very important. Otherwise some day your harddisk may get full and then mysql will be the first process which will refuse to start!
