MySQL

Creating new MySQL databases

Using ceo

Users can create their own MySQL databases through ceo. Users emailing syscom asking for a MySQL database should be directed to do so. The process is as follows:

1. SSH into any CSC machine.
2. Run ceo.
3. Select "Create MySQL database" and follow the instructions.
4. Login info will be stored in ceo-mysql-info in your home directory.
5. You can now connect to the MySQL database (from caffeine only).

Manually

To create a MySQL database manually:

$ mysql -uroot -p
Enter password: ******

mysql> CREATE DATABASE someusername;
Query OK, 1 row affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON someusername.* to someusername@localhost IDENTIFIED BY 'longrandompassword';
Query OK, 0 rows affected (0.06 sec)

For random passwords run 'makepasswd --chars 20'. For the administrative password for the cluster see /users/sysadmin/passwords/mysql.

Write a file (usually ~club/mysql) to the club's homedir readable only by them containing the following:

Username: clubuserid
Password: longrandompassword
Hostname: localhost

Try not to send passwords via plaintext email.
