check the manual that corresponds to your MySQL server version for the right syntax to use near 'IDENTIFIED BY 'xsw123456' WITH GRANT OPTION' at line 1

错误如图：

场景，mysql8.0.17修改mysql用户权限，开启所有ip可访问
使用：GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘密码‘ WITH GRANT OPTION;
报错，所以我使用如下方法
使用mysql
use mysql
修改密码：
ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘密码‘;
修改ip为所有可访问
update user set host=‘%‘ where user=‘root‘;
查看
select host,user from user;
刷新
flush privileges;

或者可以使用
ALTER USER ‘root‘@‘%‘ IDENTIFIED WITH mysql_native_password BY ‘密码‘;
flush privileges;
navicat连接，ok
