How to connect to mysql? Normally, this would be enough:

$ mysql -uroot -p this is simplest way. If your user is not root, than check your user name and substitute root with this username.

If you want to connect to database after login, do $ mysql -uroot -p mydbname

To apply dump, do:

$ mysql -uroot -p mydbname < dumpfile.sql
