Intelelgent asterisk installation episode

i install asterisk just like is defined in web site. But after that

1- it did not ask any question for configuration
2- there is no db in mysql server for asterisk .

how can asterisk run without db ?

asterisk is completely file based by default. The realtime extensions require a DB, but they aren’t enabled by default.

Look in /etc/asterisk/ for all your configuration files.
