mysql权限管理，用户管理

1 创建用户

mysql> truncate table user; //先删除所有用户

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

此命令创建一个未授权的用户

2 删除用户 

mysql> DROP USER 'username'@'domain';

3 GRANT和REVOKE语句允许系统管理员创建MySQL用户账户,授予权限和撤销权限。 

以上参考MySQL5.5手册13.5.1

4 也可以直接授权同时创建用户

mysql > GRANT ALL PRIVILEGES ON *.* TO 'monty'@'localhost' IDENTIFIED BY 'some_pass' WITH GRANT OPTION; 

mysql> GRANT SELECT,INSERT,DELETE,UPDATE ON *.* TO 'paris'@'localhost' IDENTIFIED BY '123456' WITH GRANT OPTION;

5 改完权限 或者用户 必须刷新授权表 

mysql > FLUSH PRIVILEGES;

6 改密码

mysql>SET PASSWORD FOR 'admin'@'127.0.0.1' = PASSWORD('123456');
