MySQL server login and exit
through the built-in MySQL client: the "MySQL 5.6 Command Line Client"

Login: Enter the root account password to login

Exit way: Enter the ctrl + c (directly enter, no semicolon)

Cons: This is fine for the root user login, other users can not, and therefore not flexible enough

Through Windows Client: Enter the start options bar "command prompt" -> right-click "Run as administrator" to open a command input box

Login: mysql -h host name -P port number -u user name -p Enter password to log in

For example: mysql -hlocalhost -P3306 -uroot -p password (behind the statement does not directly enter a semicolon)

If you log on the machine can be abbreviated as: mysq -u user name -p Enter password to log in

Exit way: exit (directly enter, no semicolon)

MySQL configuration environment variable
If you enter the login command in the above windows built-in client when prompted " 'mysql' is not an internal or external command, operable program
or batch file"; then the time is your environment variables not configured; look down:

Navigate to the bin directory where you installed MySQL installation, and path copy
computer - right click Properties - Advanced System Settings - Environment Variables - looking at the system environment variables inside Path- select and edit
pasted in front of the bin path just copied and state in English under the ";" at the back of the contents separated - OK - OK - OK
Note: the value of the Path is the front to back to find, you configure the command you want to open the window to turn off the rewriting to take effect
