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, first connect to the database as root:
$ mysql -uroot -p Enter password: ******
Then run the following SQL statements:
CREATE USER 'someuser'@'localhost' IDENTIFIED VIA unix_socket; CREATE USER 'someuser'@'%' IDENTIFIED BY 'longrandompassword'; CREATE DATABASE someuser; GRANT ALL PRIVILEGES ON someusername.* to 'someuser'@'localhost' IDENTIFIED VIA unix_socket; GRANT ALL PRIVILEGES ON someusername.* to 'someuser'@'%';
This will allow users to connect locally without a password, and connect remotely with a password.
For random passwords run
pwgen -s 20 1. For the administrative passwords 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.
