僅新建一個newuser用戶?
方法一：

MariaDB [(none)]> create user newuser@localhost identified by '123456'; Query OK, 0 rows affected (0.22 sec) MariaDB [(none)]> select user from mysql.user; +---------+ | user | +---------+ | aa | | root | | root | | | | aa | | bb | | lcz | | my | | mytest | | newuser | | nome | | root | | | | root | +---------+ 14 rows in set (0.00 sec) MariaDB [(none)]>

方法二：

MariaDB [(none)]> insert into mysql.user(user,host,password) values('ggo','localhost',password('1234')); Query OK, 1 row affected, 4 warnings (0.24 sec) MariaDB [(none)]> flush privileges; Query OK, 0 rows affected (0.25 sec)

效果

[root@localhost ~]# mysql -uggo -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g.

新建一個my用戶并且授權全部操作權限

MariaDB [(none)]> grant all privileges on *.* to my@localhost identified by '123456'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> select user from mysql.user; +--------+ | user | +--------+ | aa | | root | | root | | | | aa | | bb | | lcz | | my | | mytest | | nome | | root | | | | root | +--------+ 13 rows in set (0.14 sec) MariaDB [(none)]>

查看用戶權限

MariaDB [(none)]> show grants for my@localhost; +--------------------------------------------------------------------------------------------------------------------+ | Grants for my@localhost | +--------------------------------------------------------------------------------------------------------------------+ | GRANT ALL PRIVILEGES ON *.* TO 'my'@'localhost' IDENTIFIED BY PASSWORD '*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9' | +--------------------------------------------------------------------------------------------------------------------+ 1 row in set (0.00 sec)MariaDB [(none)]>
