MySQL8.x使用GRANT为用户赋权时报错的解决

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
ERROR 1064 (42000): 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 '123456' WITH GRANT OPTION' at line 1

# 创建账户
CREATE USER '用户名'@'访问主机' IDENTIFIED BY '密码';
# 为创建的账户赋权
GRANT '权限列表' ON '数据库' TO '用户名'@'访问主机';
GRANT ALL ON *.* TO 'root'@'%';
# 刷新
FLUSH PRIVILEGES;

grant all privileges on *.* to 'root'@'172.16.10.203' identified by  'password' with grant option

#创建账户
create user 'root'@'172.16.10.203' identified by  'password'
#赋予权限，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
grant all privileges on *.* to 'root'@'172.16.10.203' with grant option
#改密码&授权超用户，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
flush privileges;

创建账户::create user ‘用户名'@‘访问主机' identified by ‘密码';
赋予权限: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
