Unable to log in next door.
What should I do?

$sudo systemctl stop mysqld.service

The initial password appears in the log file, so please check it and try logging in.

How to verify the initial password for AWS EC2 AmazonLinux2 MySQL root users - Qiita

$sudoless/var/log/mysqld.log

YYYY-MM-DDTHH:MM:SS.260490Z6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost:XXXXXXXXX

The last part of XXXXXXXXXXXXXX is the password

$mysql-u root-p
 > Enter the password you just checked

also changes specifications depending on the version upgrade. In MySQL8, you may have a hard time looking at the MySQL 5 era description page.mysql.comYou may want to see the explanation of your home.

The Home Manual page automatically generates the initial password for root and logs it to the log file immediately after installing MySQL 8.Therefore, in this case, I think it is a legitimate way to find the password in the log file by looking for the MySQL log file itself.If you know the log file is /var/log/mysqld.log, open it in the editor and search for it, or grep'temporary password'/var/log/mysqld.log.If you know the initial password, you should be able to log in by giving it to the mysql command.
# sudoabbreviated

The initial password appears to be generated by a pseudo-random number.It is up to your administrator to decide whether it is appropriate to continue using the initial password in a production environment.You can change it or not.

Rebooting MySQL with mysqld --skip-grant-table in the body of the question should not be done immediately after a new installation, as it is intended to force a reset of the password for reasons such as forgetting the root password.Forget it.
