I want to bind the strapi DB with my existing MySQL DB

Hello there,
I’m implementing the strapi CMS using the Hendless CMS with Node.js, and I want to know about the following thing regarding the strapi DB, so would you please provide me the suggestions for that

  1. I want to bind the strapi DB with my existing MySQL DB, is it right why or not?
  2. Also, would you please let me know is there any disadvantage if I’ll bind my strapi DB with my existing MySQL DB?
  3. I’ve tried to bind strapi DB with my existing MySQL DB, but it is throwing the following error, and I guess it will throw this kind of error in the future if I’ll bind strapi DB with my existing DB, right?
