1.- How do I get mysql prompt in linux terminal?

mysql -u root -p

At the Enter password: prompt, well, enter root's password :)

You can find further reference by typing mysql --help or at the online manual.

It depends. Red Hat based distros have the service command:

service mysqld stop

Other distros require to call the init script directly:

/etc/init.d/mysqld stop
