Why are you looking at this wiki page?

Are you looking at this page because you cannot access the mysql server installed on your pc/server when you were trying to see if it works well? Or do you receive error messages like the following? :

 

ERROR 1045: Access denied for user: 'root@localhost' (Using 
password: NO)

or

 

ERROR 1045: Access denied for user: 'root@localhost' (Using 
password: YES)

To resolve this problem ,a fast and always working way is the „Password Resetting“ .

 

How can I reset my MySQL password?

IconsPage/IconWarning3.png Following this procedure, you will disable access control on the MySQL server. All connexions will have a root access. It is a good thing to unplug your server from the network or at least disable remote access.

To reset your mysqld password just follow these instructions :

  • Stop the mysql demon process using this command :
    •    sudo /etc/init.d/mysql stop
  • Start the mysqld demon process using the –skip-grant-tables option with this command
    •    sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking &

Because you are not checking user privs at this point, it’s safest to disable networking. In Dapper, /usr/bin/mysgld… did not work. However, mysqld --skip-grant-tables did.

  • start the mysql client process using this command
    •    mysql -u root
  • from the mysql prompt execute this command to be able to change any password
    •    FLUSH PRIVILEGES;
  • Then reset/update your password
    •    SET PASSWORD FOR root@'localhost' = PASSWORD('password');
  • If you have a mysql root account that can connect from everywhere, you should also do:
    •    UPDATE mysql.user SET Password=PASSWORD('newpwd') WHERE User='root';
