When operating the database, it prompts ERROR 1819 (HY000): Your password does not satisfy the current policy requirements.
The reason is that Mysql has added a password strength verification plug-in: validate_password. The reason for checking on the Internet is that the password set is too simple, so this problem occurs, but I set it very complicated, which is inexplicable (｀・ω・´)
Solution:
Enter mysql and enter the following commands in order to solve the problem:
mysql> SHOW VARIABLES LIKE ‘validate_password%’;
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 '‘validate_password%’' at line 1
