The CS Dept has a MySQL server available. Point your MySQL client to mysql.cs.jhu.edu

You will need a CS MySQL account for access.

Please read the following Notes...

Note 1: The 315/415/615 Databases courses use a completely different MySQL server called dbase.cs.jhu.edu. If you are taking the Databases class, you will need to get account info and instructions from your TA.

warning

Note 2: Only those with CS Linux accounts will be able to apply for a MySQL account for our mysql.cs.jhu.edu server.

warning

Note 3: You cannot ssh into mysql.cs.jhu.edu. You must connect to the MySQL server using MySQL commands or a MySQL client program, using the MySQL account we would provide you.

warning

Note 4: When your MySQL account is created, you will receive a database whose name is the same as your MySQL account.

warning

Note 5: Later, if you need an additional database set up at some point for your MySQL account, send an email to support@cs.jhu.edu letting us know your MySQL username and the proposed name of your database.

warning

Connecting to our MySQL server

Once you have your CS Department MySQL account, you can connect to the mysql.cs.jhu.edu server with:

mysql -u your-mysql-username -p -h mysql.cs.jhu.edu

You will be prompted for your MySQL password.

Changing Your MySQL Password

MySQL passwords are separate from the passwords for our Linux clients; changing your Linux password will not change your MySQL password (and vice versa).

To change your MySQL password, connect to mysql.cs.jhu.edu with a MySQL client, and run the following command: 

SET PASSWORD = PASSWORD('your-new-password');

Replace your-new-password with what you want your password to be.

Please be aware that many MySQL clients keep a record of SQL queries. You should clear that record to keep your MySQL password safe. On Linux systems, the command line MySQL client keeps its statement log in ~/.mysql_history; we recommend removing that file after changing your MySQL password. Other clients may store their history in other places.
