MySQL8.0 retrieve password
1. The MySQL8.0 service is deployed on the Windows server, and the password needs to be retrieved. But according to the conventional method, my.iniadding skip-grant-tablesparameters to the file and restarting MySQL did not take effect
C:\Users\EDZ>mysql -uroot -p
Enter password:
ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost:3306' (10061)
2. After data search, the following methods are adopted:
Tried mysqld --skip-grant-tablesthe command, but still can't log in without password
mysqld --console --skip-grant-tables --shared-memory
D:\software\MySQL\mysql-8.0.27-winx64\bin>mysqld --console --skip-grant-tables --shared-memory
