Start MYSQL error
I searched a lot on the Internet, saying that it was to configure a certain file or delete a certain file. The following pro test is valid, PS: MYSQL installation tutorial
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
It means that the password was entered, but an error was reported.
Solution:
re-enter:
mysql -u root -p
Now let you enter the password:
Enter password:
Press Enter directly at this time, do not enter the password! ! !
Press Enter directly at this time, do not enter the password! ! !
Press Enter directly at this time, do not enter the password! ! !
Say the important thing three times!
You will find that MYSQL is successfully started: (It's so weird...)

If you want to enter the password to start, you need to reset the password:
Input: mysql> ALTER user'root'@'localhost' IDENTIFIED BY '123456';
set the password to 123456. ( I still don’t know why I can enter without a password, and I need to reset my password. But it works)
mysql> ALTER user 'root'@'localhost' IDENTIFIED BY '123456';
