I can't use mysql

Asked by pdo100 on 2007-09-02

Recently I installed Apache2, php and mysql... I configured apache2 and the www folder is now in my user folder and I can access easily and do some stuff... now I am due to use mysql and when I go to terminal and try to start mysql or do anything with it I get message: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
How can I make it working? how can I start doing something with mysql? I need to use GUI option for other apache work, so how is it possible to use terminal while logged on as user?

BTW I am the only user on the machine...

to acces the terminal :applications->accesories->terminal
the so called error is not related to ubuntu
try to use "-u root" option when working with mysql
try to connect from inside a php script

Mysql has it's own users which are different from the system users. At some point the mysql root user was assigned a password and expects that password to be provided when using mysql.
(i.e. mysql -u root -prootpassword databasename) (no space after -p)

You might need to reset the mysql root password for this to work. Details are here:

As far as I read from mysql site once it was install root username was given and password was not setup... so why I still have the same problem when typing ~mysql - root

I managed to change the root password but the same message appears on screen: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

I tried to type:
:~$ mysql -u root -p
:~$ password: *****

and still the same...

and also when I type ~: mysqld
following message comes on the screen:

pdo100, you're receiving permission errors because the mysql daemon needs to be started with root privs:

sudo /etc/init.d/mysql start

Thanks Sean Sosik-Hamor, that solved my question.
