Good Night Personal,
I just installed wampserver, later I was able to access phpmyadmin, but I found something strange in user accounts.
As users only had mysql.sys and root, being the root that I created.
Can anyone tell me about this? And something from the phpmyadmin version?
Since MySQL 5.7.7 a Schema is created to facilitate the performance statistics managed by engine PERFORMANCE_SCHEMA , and it is just the sys .
This user was also created (called DEFINER in this context):
'mysql.sys'@'localhost'
This was done to avoid problems, because before DEFINER was
'root'@'localhost'
and this created a lot of problems when the user root was renamed, which is a very common security procedure.
Creating a dedicated, local-only user was the solution found.
More details in the manual:
