语法

mysql> CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';

mysql> GRANT ALL ON [dbname].[table] TO 'username'@'localhost';

实现

首先登录到mysql的root帐户和使用下面的命令在mysql中创建拥有全部权限的新用户Hyman。
但是该用户只能从本地主机访问数据库服务器。

mysql> CREATE USER 'Hyman'@'localhost' IDENTIFIED BY 'password';
mysql> GRANT ALL ON *.* TO 'Hyman'@'localhost' IDENTIFIED BY 'secret_password';
mysql> FLUSH PRIVILEGES;

现在，尝试使用新密码登录

# mysql -u Hyman -p'password'
