Backup MYSQL Databases (no PHPAdmin or Plesk)

Hello everyone; For some strange reason my PLESK Licence is not valid. I most likely moved some files around in ROOT and need to do a clean install and need my MYSQL databases backed up. But the problem for me is, I do not have 'myphpadmin' access or access anywhere in plesk. You would need to SSH in and dump all databases into individual dump files so i can import later. This is a very small project, so please do not try to charge me an arm and a leg. I can do it i just do not have time in the next few days,
