Creating new MySQL databases
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:
- SSH into any CSC machine.
- Run ceo.
- Select "Create MySQL database" and follow the instructions.
- Login info will be stored in ceo-mysql-info in your home directory.
- You can now connect to the MySQL database (from caffeine only).
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.
See the history of this page for information on the previous replication setup.
Deleting MySQL databases
Users can delete their own MySQL databases.
SSH into caffeine.
mysql -u yourusernamehere -p Enter password: ****** DROP DATABASE database name goes here
Login info and database name was created on database creation in ceo-mysql-info in your home directory.
