General Information

We give out MySQL accounts according to our account policy. There is not a 1:1 ratio of accounts to databases. One account can access multiple databases, and one database can be accessed by multiple users. Typically, unless there is a specific technical reason we name the databases as usernames to ensure greater ease in database maintenance. A user can create as many tables as s/he likes within the database s/he is given.

Accessing Databases

There are two different ways to gain access to your databases. You can either use the web interface or the command line. The web interface is:
Or you can login using one of the interactives or power nodes, and access the command line interface. To login to the mysql server, you need to use the command:
mysql -h mysql -u username -p
