mysqladmin -u root password 'root'

As an AI language model, I cannot execute commands on your device. However, assuming that you are trying to set the password for the MySQL root user using the command line interface, the correct syntax would be:

mysqladmin -u root password 'newpassword'

Replace 'newpassword' with the desired password for the root user. Note that it is recommended to use a strong password that is at least 8 characters long and includes a mix of uppercase and lowercase letters, numbers, and special characters.

若用户名root密码password,则查看mysql服务是否正常的指令是（）。 A. mysql -uroot -ppassword ping B. mysqladmin -uroot -ppassword ping C. mysqladmin -uroot -ppassword D.mysqladmin -u -p ping

B. mysqladmin -uroot -ppassword ping

解析：查看MySQL服务是否正常，可以使用mysqladmin命令行工具中的ping子命令。正确的命令是：

mysqladmin -uroot -ppassword ping

其中，-u选项指定用户名为root，-p选项指定密码为password，ping是mysqladmin的子命令，用于检测MySQL服务是否正常。如果MySQL服务正常，会返回一个类似于“mysqld is alive”的消息。因此，选项B是正确的。选项A中，mysql命令行工具没有ping子命令；选项C中，多了一个空格，不正确；选项D中，-u和-p选项后面没有指定用户名和密码，不正确。

mysqladmin -u root -p shutdown

This command is used to shut down the MySQL server using the mysqladmin utility. "-u root" specifies the username as root, "-p" prompts for the password, and "shutdown" is the command to be executed. Once executed, the MySQL server will be shut down. It is important to note that this command should only be used if necessary, as shutting down the server will interrupt any active connections or processes.
