mysql 8.0.12 创建并授权出现的问题

实际代码

mysql> grant all privileges on database.* to 'user'@'localhost' identified by 'password';

异常信息

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'identified by 'password'' at line 1

解决方案

将用户创建过程和授权过程分开

mysql> create user 'luffy'@'localhost' identified by  'luffy';
Query OK, 0 rows affected (0.04 sec)

mysql> grant all privileges on luffy.* to 'luffy'@'localhost' with grant option;
Query OK, 0 rows affected (0.09 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

flush privileges 命令本质上的作用是将当前user和privilige表中的用户信息/权限设置从mysql库(MySQL数据库的内置库)中提取到内存里

创建用户::create user ‘用户名’@‘访问主机’ identified by ‘密码’;
授予权限:grant 权限列表 on 数据库 to ‘用户名’@‘访问主机’ ;
with grant option这个选项表示该用户可以将自己拥有的权限授权给别人
