After installing a new mysql in red hat 6.3, I found that the initial password root could not log in, and an error occurred
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
The solution is as follows:
#service mysqld stop
#mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
#mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
mysql> FLUSH PRIVILEGES;
mysql> quit
service mysqld restart
# mysql -uroot -p
Enter password: <Enter the new password newpassword>
mysql> quit
Bye
[root@localhost Desktop]# mysql -u root -p;
Enter password:
