注意:(mysql数据库不区分大小写,但符号一定要用英文格式)
**查看用户命令:**select user,authentication_string,host from user;
** 创建用户命令一,直接创建:**create user 'zhangsan'@'localhost' identified by 'abc123';
**创建用户命令二,权限创建:**grant all on . to 'lisi'@'localhost' identified by 'abc123';
**更改密码命令:**set password for 'zhangsan'@'localhost' = password('123abc');
**更改用户名:**rename user 'lisi'@'localhost' to 'wangwu'@'localhost';
密码忘记时解决办法(mysql5.7版本)
在【mysqld】下面插入
skip-grant-tables
