Brief installation steps

Find the detailed installation steps on the wiki.

If you are upgrading, check the Release notes.

Steps in brief:

1. Extract to web root folder (eg: /var/www/html => Ubuntu)
2. Run composer install from there to get & check the dependencies.
3. Create the gammu smsd database.
   • Kalkun uses the database that is created by gammu with all the tables created by gammu. Kalkun then adds tables and some columns. So there is no such case where one has a gammu database separate from the kalkun database. Both software share the same database.
4. Import gammu database schema (it's included on gammu sources, eg. gammu/docs/sql/mysql.sql).
5. Configure Kalkun daemon & outbox_queue scripts (to manage inbox and autoreply)
6. Optionally: increase the security of your installation
7. Configure the connection to the database in application/config/database.php
8. Launch the install wizard of Kalkun, preferably by going to http://localhost/kalkun/index.php/install
9. Delete the installation file (the install wizard tell you where it is, if this step is needed)
10. Change the default encryption key in application/config/config.php
11. Launch Kalkun by browsing to http://localhost/kalkun. Default login and password are kalkun.
