How to start MySQL as root?
Use the following command to begin a MySQL session as the root MySQL user. This command includes the -p option, which instructs mysql to prompt you for a password in order to log in.

This will force the client to connect with TCP instead of using the local socket file. MySQL attempts to make connections through a Unix socket file by default. This is generally faster and more secure, since these connections can only be made locally and don’t have to go through all the checks and routing operations that TCP connections must perform. Connecting with TCP, however, allows us to check the SSL status of the connection:
