This situation appears as shown in the figure:
Reason 1 : The password is entered incorrectly!
Think carefully about what your password is and try a few more times. If you can’t get up first, re-run the MySQL repair tool and reset the password
Reason 2 : The root account does not open remote access permissions by default
. You need to modify the relevant permissions.
解决方案：
1. Open the my.ini file under the MySQL directory (mine is C:\Program Files (x86)\MySQL\MySQL Server 5.5), edit it, add a line "skip-grant-tables" at the end of the file, save and Close the file. Some put the my.ini file in the hidden Program data file for safety.
2. Open the service and restart the MySQL service.
Reason three : mysql server stops
Restart the MySQL service:
net start mysql
My question: Forgot password
It’s very normal to forget your password if you don’t use MySQL for a long time. So, any study and work must be backed up and recorded. Maybe one day your database will fall.
