### 结束进程 ###
mariadb10.6的服务不叫"mariadb"
C:\Users\Administrator>tasklist |findstr mariadb
查看服务名"mysql"的进程号（PID号是5636，因每次都不同，所以用一次查看一次)
C:\Users\Administrator>tasklist |findstr mysql
mysqld.exe 5636 Services 0 47,116 K
结束该进程号
C:\Users\Administrator>taskkill /pid 5636
ERROR: The process with PID 5636 could not be terminated.
Reason: This process can only be terminated forcefully (with /F option).
这里要加参数（/f），强制执行
C:\Users\Administrator>taskkill /pid 5636 /f
SUCCESS: The process with PID 5636 has been terminated.
### 跳过验证 ###
我的安装目录是默认的在C盘
下面这条命令不适合我这个版本
C:\Program Files\MariaDB 10.6\bin>mysqld_safe --defaults-file=/etc/my.cnf --skip-grant-tables &
'mysqld_safe' is not recognized as an internal or external command,
operable program or batch file.
mariadb用这条命令跳过验证
C:\Program Files\MariaDB 10.6\bin>mysqld --defaults-file="c:\Program Files\MariaDB 10.6\data\my.ini" --console --skip-grant-tables

使用"mysql"数据库

更新root密码，不成功
MariaDB [mysql]> update user set password=password('123456789') where user='root';
ERROR 1348 (HY000): Column 'Password' is not updatable
换一种方式，提示正在运行前面的跳过"--skip-grant-tables"。需要刷新一下先
MariaDB [mysql]> alter user 'root'@'localhost' identified by '123456789';
ERROR 1290 (HY000): The MariaDB server is running with the --skip-grant-tables option so it cannot execute this statement
刷新
MariaDB [mysql]> flush privileges;

再试一次更新密码，成功
MariaDB [mysql]> alter user 'root'@'127.0.0.1' identified by '123456789';
