- 2. First, you need to set the verification strength level of the password, and set the global parameter of validate_password_policy to LOW.
Enter the setting statement set global validate_password_policy=LOW; to set the value,
- 3. The current password length is 8. If you don’t mind, you don’t need to modify it. Generally speaking, set it to a 6-digit password, and set the global parameter of validate_password_length to 6.
Enter the setting statement set global validate_password_length=6; to set the value,
- 4. Now you can set a simple password for mysql, as long as it meets the length of six digits,
Enter the modification statement ALTER USER 'root'@'localhost' IDENTIFIED BY '123456'; You can see that the modification is successful, indicating that the password policy modification is successful! ! !
Note: The minimum length of the default password is 4, consisting of one uppercase/lowercase letter + one Arabic numeral + one special character,
As long as the length of the set password is less than 3, it will be automatically set to 4,
