Start mysql with mysqld_safe and --skip-grant-tables to skip permission auditing.

[root@localhost ~]# mysqld_safe --skip-grant-tables &   

Log in

[root@localhost ~]# mysql --user=root mysql

In this way, you can enter the mysql environment and change the user password. Set the root user password to 111111

mysql> update user set authentication_string=PASSWORD('111111') WHERE User='root';

refresh permissions

mysql> flush privileges;
Query OK, 0 rows affected (0.06 sec)

mysql> QUIT;

Then log in with the new password to enter

[root@localhost ~]# mysql -uroot -p111111
