MySQL log in and log out

1.

I found on the official web download link, but the download speed is relatively slow, with the Thunderbolt 7, some parts from the mirror, etc., but should also be OK ...
Download the free install version of Mysql-noinstall-5.1.73-win32.zip

In Baidu Cloud (jeehuanjing)---mysql_in_windows inside, there is backup to save.

2.

Directory "... \mysql-noinstall-5.1.73-win32\bin", cmd command:

2.1, open MySQL:mysqld--console;
Close MySQL:mysqladmin-uroot shutdown;
2.2, log in:mysql-u root;
Logout:exit; / quit;
