mysql8安装后如何修改root密码

Posted 2022-03-16 saysmy

mysql5.7.9之后，就没有了password函数，所以，使用传统的password()函数修改root密码的话，就会提示sql错误

 

 UPDATE user SET authentication_string = password(‘123456‘) WHERE User=‘root‘;

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 ‘(‘123456‘) WHERE User=‘root‘‘ at line 1

 

 

正确设置密码的方法是：

ALTER USER ‘root‘@‘localhost‘ IDENTIFIED WITH mysql_native_password BY ‘123456‘;

此时提示修改成功，退出mysql再次登陆即需要输入刚刚设置的密码。
