It's a lot, and there's a role. The default corresponding global privileges
In fact, there is no need to remember (I feel no need to remember), about the global privileges also know a super, because these days have been engaged in this, other role, today for the first time know that MySQL has role.
After you have installed MySQL and Workbench, you can see in Workbench's users and privileges that role and global privileges default correspondence, directly below two images
And the inclusion relationship between roles and so on, I just found out when I checked DBA role.
Roles and Global privileges are all here (I guess), and the reason for this is to install X.
