## Database
|
|
|
|
|
SYZOJ 2 uses [Sequelize](http://sequelizejs.com), which supports many database systems, including MySQL and Sqlite.
|
|
|
|
|
|
|
|
|
|
By default it use the Sqlite database `syzoj.db`, you can change it in `config.json`
|
|

|
|
|
|
You should change the `session_secret` and `judge_token` in `config.json`.
|
|
|
|
|
|
|
|
|
|
# Administration
|
|
|
|
|
In the database, the `is_admin` field in `user` table describes whether a user is admin or not.
|
|
|
|
|
|
|
|
|
|
To make a user be an admin, the only way is via database.
