It depends, the running services should answer ... for a mysqld running system:
Delete the -x option above and add
--exclude /proc --exclude /sys --exclude /mnt --exclude /var/lib/mysql
and then
mysqldump --add-drop-table -c --create-options -x -u root -p -A > mysqldump-$(date +%s).sql
for example ...
--
