解决mysql的赋权操作之GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘123456‘ WITH GRANT OPTION问题

一种情况

mysql的赋权操作:GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘123456‘ WITH GRANT OPTION;

mysql赋权操作:

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

flush privileges;
GRANT:赋权命令
ALL PRIVILEGES:当前用户的所有权限
ON:介词
*.*:当前用户对所有数据库和表的相应操作权限
TO:介词
‘root’@’%’:权限赋给root用户,所有ip都能连接
IDENTIFIED BY ‘123456’:连接时输入密码,密码为123456
WITH GRANT OPTION:允许级联赋权

20200901:
将GRANT语句通过代码块包起来

二种情况

mysql中远程连接权限语句grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘123456‘ with grant optio报错

grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘123456‘ with grant optio

原因: mysql的版本问题,这条语句适用于MySQL8.0之前

解决: mysql8.0及以上版本需要使用以下语句:

create user root@
