Hi,  I am trying to create a simple database for class and do not have permission when entering commands in MySQL monitor.  Sure this is simple but having a difficult time.  Can someone assist?  I am using a WAMP localhost on my Win 7 64 bit machine.

Are you logged into MySQL with the username/password? If this is a default install then it would be root and empty password.

Deanna Andru:

After you create the database, you have to grant permissions to the tables, and the user(s).  the GRANT command tells it which tables the user has credentials for.  The 'ALL' after the GRANT says the user all privileges on the tables specified after the ON clause.  The <database name>.* indicates the user has these privileges on all tables in the database.

The SET PASSWORD line assigns the password to the username specified.  The term after the @ says from what hostname or IP address the user would be logging in from.  This enables you to allow a user to log in only from certain hostnames or IP addresses.  The '%' in the example below says to let the user log in from any host.

CREATE DATABASE
<database name>;

GRANT ALL ON <database name>.* TO <username> IDENTIFIED BY '<password>';

SET PASSWORD FOR '<username>'@'%' = OLD_PASSWORD('<password>');

Hope this helps.  Best regards,

AielloJ

I reinstalled WAMP.  When accessing the phpMyAdmin panel I see the following error:
Your configuration file contains settings (root with no password) that correspond to the default MySQL privileged account. Your MySQL server is running with this default, is open to intrusion, and you really should fix this security hole by setting a password for user 'root'.
At this point, I cant create a database. and I don't know where to find the terminal.

For local development it's fine to just use root.
If you installed WAMP then it will have installed PHPMyAdmin which you will normally access with
http://localhost/phpmyadmin
(easier than using a terminal)

Thank you for the assist, I was able to locate the mysql terminal.  The instructions say to begin by typing at the mysql> prompt: mysql -h host -u user -p.  With this I am able to use it.  I am still unsure of the permissions with the error at phpMyAdmin panel:  

"Your configuration file contains settings (root with no password) that correspond to the default MySQL privileged account. Your MySQL server is running with this default, is open to intrusion, and you really should fix this security hole by setting a password for user 'root'."

Working on the assignment and will update with any issues or errors.

It's just a warning, to get rid of it set a password on the root account.

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

You can only have one root account, once you set the password then you will need that to login to MySQL

You don't need to reinstall, just log in using root and the password you set

Hi again,  I installed XAMP with an admin account on my win 7 64 bit machine this time.   The instructions for the initial setup at the beginning of class was for WAMP, the instructor now shows an example for XAMPP  when accessing phpMyAdmin.  I am a total newbe.   How do I log in using root and the password if I never set a password on the local machine exactly?   I now have XAMPP v3.2.1 installed and am able to follow class instructions precisely - hopefully.  Will check back.

If you never set a password during the installation then there is no password - it's blank

I am able to follow the instructions in XAMPP administrator window for mysql with this setup.  I was able to create a database without any permission issues so far.  :-)
