如何创建具有有限权限的 MySQL 用户?
mysqlmysqli database
要创建具有有限权限的 MySQL 用户，以下是语法 −
CREATE USER 'yourUserName'@'yourHostName' IDENTIFIED BY 'yourPassword';
以下是为用户 − 设置有限权限的语法
GRANT SELECT、INSERT、UPDATE 等 REFERENCES ON yourDatabaseName.* TO 'yourUserName'@'yourHostName';
让我们实现上述语法，以便创建一个具有有限权限 − 的 MySQL 用户
mysql> CREATE USER 'David'@'localhost' IDENTIFIED BY 'david'; Query OK, 0 rows affected (0.20 sec) mysql> GRANT SELECT, INSERT, UPDATE, DELETE, ALTER, CREATE, REFERENCES ON test.* TO 'David'@'localhost'; Query OK, 0 rows affected (0.21 sec)
让我们检查是否已使用名称 ‘David’ 创建用户。
mysql> select user, host from MySQL.user;
这将产生以下输出 −
+------------------+-----------+ | user | host | +------------------+-----------+ | Bob | % | | User2 | % | | mysql.infoschema | % | | mysql.session | % | | mysql.sys | % | | root | % | | @UserName@ | localhost | | Adam Smith | localhost | | David | localhost | | James | localhost | | John | localhost | | John Doe | localhost | | User1 | localhost | | am | localhost | | hbstudent | localhost | | mysql.infoschema | localhost | | mysql.session | localhost | +------------------+-----------+ 17 rows in set (0.00 sec)
