Setup SQL references non-existant variables and incorrect service

[wingzero54]

  mysql_db: "name={{ global_mysql_database }} 

global_mysql_database is not defined anywhere

  mysql_user: "name={{ global_mysql_user }} password={{ global_mysql_password }} login_password={{ mysql_root_pass }} login_unix_socket={{ mysql_socket_location }} priv={{ global_mysql_database }}.*

global_mysql_user and global_mysql_password is not defined anywhere

My assumption is these variables are all supposed to be in either variables/all.yml or variables/passwords.yml

  service:
    name: mariadb

Per the MariaDB documentation the service is called mysql, mariadb is not a recognized service
