My system is ubuntu6.06, recently installed good MySQL in the MySQL tool, always have the error tip:
# mysql-uroot-p
Enter Password:
ERROR 1045 (28000): Access denied for user ' root ' @ ' localhost ' (using Password:no)
use the method described on the web to modify the password of the root user:
# mysqladmin-uroot-p password ' newpassword '
Enter Password:
Mysqladmin:connect to server at ' localhost ' failed
Error: ' Access denied for user ' root ' localhost ' (using Password:yes) '
Now finally I found the solution, as follows (please test method three, thank you!) ):
method One:
#/etc/init.d/mysql 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
#/etc/init.d/mysql Restart
# mysql-uroot-p
Enter Password: < Enter the new password newpassword>
Mysql>

Method Two:
Use the username and password provided directly in the [client] section of the/etc/mysql/debian.cnf file:
# mysql-udebian-sys-maint-p
Enter Password: < Enter the password for [client] section >
mysql> UPDATE user SET Password=password (' NewPassword ') where user= ' root ';
mysql> FLUSH privileges;
Mysql> quit
# mysql-uroot-p
Enter Password: < Enter the new password newpassword>
Mysql>

Method Three:
This method I did not have to test, because my root user default password has been modified by me, that a free test, tell me the results, thank you!!
# mysql-uroot-p
Enter Password: < Enter the password provided in the [Client] section of/ETC/MYSQL/DEBIAN.CNF file >
At this point, puzzled over the problem solved!
