本节内容：
mysql中创建用户、mysql用户授权、mysql删除用户、mysql修改暗码实例详解.MYSQL应用
一,mysql创建用户:
命令:CREATE USER ' IDENTIFIED BY 'password';
说明:username - 你将创建的用户名, host - 指定该用户在哪个主机上可以登陆,如果是本地用户可用localhost, 如果想让该用户可以从任意远程主机登陆,可以使用通配符%. password - 该用户的登陆暗码,暗码可以为空,如果为空则该用户可以不需要暗码登陆服务器.
例子:
MYSQL应用
CREATE USER ' IDENTIFIED BY '123456';
CREATE USER _' IDENDIFIED BY '123456';
CREATE USER ' IDENTIFIED BY '123456';
CREATE USER IDENTIFIED BY '';
CREATE USER ;
二,mysql用户授权:
命令:GRANT privileges ON databasename.tablename TO
说明: privileges - 用户的操作权限,如SELECT , INSERT , UPDATE 等(详细列表见该文最后面).如果要授予所的权限则使用ALL.;databasename - 数据库名,tablename-表名,如果要授予该用户对所有数据库和表的相应操作权限则可用*表现, 如*.*.MYSQL应用
例子:
MYSQL利用
GRANT SELECT, INSERT ON test.user TO ;
GRANT ALL ON *.* TO ;
注意：以上命令授权的用户不克不及给其它用户授权,如果使该用户可以授权,使用命令:
MYSQL应用
GRANT privileges ON databasename.tablename TO WITH GRANT OPTION;
三,设置与更改用户暗码
命令：SET PASSWORD FOR = PASSWORD('newpassword');如果是当前登陆用户用SET PASSWORD = PASSWORD("newpassword");
例子：
MYSQL应用
SET PASSWORD FOR = PASSWORD("123456");
四,撤销用户权限
命令: REVOKE privilege ON databasename.tablename FROM ;
说明: privilege, databasename, tablename - 同授权部门.MYSQL应用
例子:
MYSQL利用
REVOKE SELECT ON *.* FROM ;
注意：MYSQL利用
假如在给用户授权的时候是这样的(或类似的):GRANT SELECT ON test.user TO ,则在使用REVOKE SELECT ON *.* FROM ;命令并不克不及撤销该用户对test数据库中user表的SELECT 操作.
相反,如果授权使用的是GRANT SELECT ON *.* TO ;则REVOKE SELECT ON test.user FROM ;命令也不克不及撤销该用户对test数据库中user表的Select 权限.
具体信息可以用命令SHOW GRANTS FOR ; 查看.
五,删除用户
命令: DROP USER ;MYSQL应用
