Question

Locked out of MySQL

Posted October 16, 2019 1k views

Hi guys,

So, I’ve just tried to secure my mysql connection and put a password which I read was the right thing to do.

Having said that, now I can’t actually connect to MySQL using the following command

mysql

It says I don’t have access. I’m at a loss, what to do?

The good thing is, my applications are running

Hi @Remdore,

Don’t worry, you can still enter your mysql like that

mysql -u root -p

That will connect you with your root user once you provide your password.

Having said that, if you don’t want to type in your password every single time, there is a solution to the problem as well. Create a file at the following location

touch ~/.my.cnf

In the file put the following

vi ~/.my.cnf

[mysql]
user=root
password=YourPAsswordHere

That should be enough for you to be able to enter your MySQL service just by typing mysql.

    Thank you, that worked like a charm.

    Despite this, I noticed other issues. I now can’t access my mysqladmin options. I tried with and without providing a password but the end result was the same.

      Glad to hear it’s working.

      To resolve the issue you are facing now, in the same file 

      ~/.my.cnf

      You can add the following 

      [mysqladmin]
user=root
password=YourPAsswordHere

      The principle is the same for every other command you’ll want to execute.

        Thank you!

        So you are saying that in theory if my mysqldump command doesn’t work(haven’t tested it out yet) with the same error for needing a password, I can just add it to the file .my.cnf like this

        [mysqldump]
user=root
password=

        It will be fine?

        What If I want to use another user than root, will I be able to?

          Hi @Remdore, you are getting the hang of it!

          Yes, setting that in your ~/.my.cnf file will work and you’ll be able to use mysqldump just the way you described it.

          As for your second question, you’ll still be able to connect or dump a database using another user. The lines you’ve added to your file don’t in anyway prevent you from doing so.

          Regards,
