[fix]-MySQL ERROR 1045 (28000) Access denied for user bill@localhost (using password YES)
Scenario:
ERROR 1045(28000): Access denied for user 'root@localhost' (using password: no)
Error:
MySQL ERROR 1045 (28000): Access denied for user @'localhost' (using password: YES)
Fix 1:
Login with root and then change the user password with the below command:
update user set password=PASSWORD("YOURPASSWORDHERE") where User=’[Enter the UserName here]';Fix 2:
In Linux, the configuration files can be analyzed to find the password. In case
- If the password is not available or
- The root login as well is not working.
Use the below commands to stop and re-start the server:
sudo /etc/init.d/mysql stop
Now start MySQL in safe mode to skip the privileges table as:
sudo mysqld_safe --skip-grant-tables &
Login with root:
mysql -uroot
And assign the DB that needs to be used:
use mysql;
Now all you have to do is reset your root password of the MySQL user and restart the MySQL service:
update user set password=PASSWORD(‘[Enter the password here]’) where User='root';
flush privileges;
Now quit from the database and restart MySQL server with below commands:
quit
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start
Now the root password should be working. Use the below command to test it:
mysql -u root -p
Fix 3:
Follow the steps below.
1. Start the MySQL server instance or daemon with the
--skip-grant-tables option as follows.
$ mysqld --skip-grant-tables
2. Execute the below commands:
$ mysql -u root mysql
$mysql> UPDATE user SET Password=PASSWORD('Enter password here') where USER='root';
$mysql> FLUSH PRIVILEGES;
3. If the password error still occurs:
update user set authentication_string=password('Enter password here') where user='root';
4. Finally, restart the instance without the --skip-grant-tables option as:
$ /etc/init.d/mysql restart
5. Now login with the new password.
Fixes are applicable to the following versions of MySql:
1. MySQL 3.23
2. MySQL 4.0
3. MySQL 4.1
