Note that during the installation process, MySQL has defaulted that the password of user root is no longer root, but a temporary password dynamically generated (eg root@localhost: yltGn*gPH9t,).
During the installation process, a pop-up window will appear to tell you the dynamic password. Be sure to remember this or copy the password, which is related to whether you can enter the database.
