MySQL accounts are available upon request to all students and faculty in the EECS department. If you do not already have an account and would like to start one submit a request for an account by submitting a help ticket. Read the follow sections for more information about and restrictions on EECS MySQL Accounts.

Class accounts are created for EECS users enrolled in EECS courses that require database usage (for example EECS 647). Class accounts are temporary, and are purged after the course is completed.

Persistent accounts are created upon request and persist as long as the user's EECS account is active. A class account can be converted into a persistent account by following the procedure described in the section above.

Each EECS MySQL Account begins with a 10MB quota placed upon it. If at anytime the size of a user's database exceeds that of their quota their ability to run INSERT, CREATE, and UPDATE queries is automatically revoked. If this happens it may cause errors in programs connected to the MySQL database. It is the users responsibility to keep track of the size and status of their MySQL database to prevent such errors from occurring. Database privileges that have been revoked in this fashion will automatically be returned once the size of the database is beneath its designated quota. Each time permissions are revoked or granted a notification email is generated and sent to the user's EECS email address.

To view the current status of your MySQL Account visit https://www.eecs.ku.edu/account/mysql.

If you have a compelling reason why the quota on you MySQL Account should be increased, submit a request using the EECS help ticket system.

1. Each EECS user is limited to a single MySQL database of the same name as the user's EECS username.
2. Access to the MySQL server is limited to computers on the EECS network. You will not be able to connect directly to your MySQL database from you home computer.
3. You may not use your EECS MySQL Account for business purposes (an e-commerce website), or to store sensitive information (such as credit card numbers, social security numbers, etc.).
4. EECS MySQL Accounts are NOT backed up! For more information see MySQL Backups.

To access the MySQL command line client log into mysql.eecs.ku.edu using your EECS username and password and enter the command below. You will then be prompted to enter your MySQL account password (which you will find on your EECS MySQL Database Account Handout).

mysql -u username -p

To access the MySQL command line client while logged into another Cycle Server or an EECS Linux workstation user the following command:

mysql -h mysql.eecs.ku.edu -u username -p

For help with MySQL commands type help, to exit the client type exit.

To change your MySQL account password login to the MySQL command line client, as described above, and execute the following command:

SET PASSWORD = PASSWORD('new_password');

If you would like to make a connection to your MySQL database from a program located on an EECS computer use the following information:

• hostname: mysql.eecs.ku.edu
• username: your_username
• password: your_password
• database: your_database (same as your username)

EECS MySQL Databases are NOT backed up! EECS users are responsible for backing up their own MySQL databases. To backup your MySQL database use the following command:

mysqldump -u username -p username > backup.sql

If it is important that your database be backed up regularly use crontab to automate your backups.

You can also access your EECS MySQL database using the PHPMyAdmin web client from any web browser at https://mysql.eecs.ku.edu. Use your MySQL account username and password to access.
