We assumed that 'nobody' is running Apache. First we must create a 'nobody' user in your Interbase Server (using gsec) and fills preferences at config/config.inc.php3 to setup your web and mail servers. Secondly, we are going to create our db and setup twig db configuration: 1) Run where you want to install the database: cd [my database path] isql -i [my twig path]/setup/twig.table.ibase Note: Database scheme "twig.table.ibase" is given from isql -x, so you should edit twig.table.ibase to change the path of your .gdb. Uncomment CREATE DATABASE lines. 2) cd [my twig path]/config 3) edit dbconfig.inc.php3 fills 'nobody' password $dbconfig["defaultdb"] = "[my database path]/twig.gdb" $dbconfig["sqltype"] = "ibase"
