Rubycas-server配置

There appears to be a database problem. Your application's database configuration file might be written incorrectly. Please check it and fix any errors. The database server may not be running. Please check whether it's running, and start it if it isn't. Error message: ActiveRecord::AdapterNotSpecified (ActiveRecord::AdapterNotSpecified) Exception class: ActiveRecord::AdapterNotSpecified

原因如下：

RubyCAS-Server still needs a database for storage of various internals (session and login tickets, etc.)

若不想用mysql，则配置为用sqlite即可
