492rt-setup-database - Set up RT's database
493
494=head1 SYNOPSIS
495
496 rt-setup-database --action ...
497
498=head1 OPTIONS
499
500=over
501
502=item action
503
504Several actions can be combined using comma separated list.
505
506=over
507
508=item init
509
510Initialize the database. This is combination of multiple actions listed below.
511Create DB, schema, setup acl, insert core data and initial data.
512
513=item upgrade
514
515Apply all needed schema/acl/content updates (will ask for version to upgrade
516from)
517
518=item create
519
520Create the database.
521
522=item drop
523
524Drop the database. This will B<ERASE ALL YOUR DATA>.
525
526=item schema
527
528Initialize only the database schema
529
530To use a local or supplementary datafile, specify it using the '--datadir'
531option below.
532
533=item acl
534
535Initialize only the database ACLs
536
537To use a local or supplementary datafile, specify it using the '--datadir'
538option below.
539
540=item coredata
541
542Insert data into RT's database. This data is required for normal functioning of
543any RT instance.
544
545=item insert
546
547Insert data into RT's database. By default, will use RT's installation data.
548To use a local or supplementary datafile, specify it using the '--datafile'
549option below.
550
551=back
552
553=item datafile
554
555file path of the data you want to action on
556
557e.g. C<--datafile /path/to/datafile>
558
559=item datadir
560
561Used to specify a path to find the local database schema and acls to be
562installed.
563
564e.g. C<--datadir /path/to/>
565
566=item dba
567
568dba's username
569
570=item dba-password
571
572dba's password
573
574=item prompt-for-dba-password
575
576Ask for the database administrator's password interactively
577
578=item skip-create
579
580for 'init': skip creating the database and the user account, so we don't need
581administrator privileges
582
583=item root-password-file
584
585for 'init' and 'insert': rather than using the default administrative password
586for RT's "root" user, use the password in this file.
587
588=back
