.. _cubicweb-ctl:

``cubicweb-ctl`` tool

=====================

`cubicweb-ctl` is the swiss knife to manage `CubicWeb` instances.

The general syntax is ::

  cubicweb-ctl <command> [options command] <arguments commands>

To view available commands ::

  cubicweb-ctl

  cubicweb-ctl --help

Please note that the commands available depends on the `CubicWeb` packages

and cubes that have been installed.

To view the help menu on specific command ::

  cubicweb-ctl <command> --help

Command to create a cube

------------------------

* ``newcube``, create a new cube on the file system based on the name

  given in the parameters. This command create a cube from an application

  skeleton that includes default files required for debian packaging.

Command to create an instance

-----------------------------

* ``create``, creates the files for the instance configuration

* ``db-create``, creates the system database of an instance (tables and

  extensions only)

* ``db-init``, initializes the system database of an instance

  (schema, groups, users, workflows...)

By default, those three commandes are encapsulated in ``create`` so

that they can be executed consecutively.

Command to create an instance for Google AppEngine datastore source

-------------------------------------------------------------------

* ``newgapp``, creates the configuration files for an instance

This command needs to be followed by the commands responsible for

the database initialization. As those are specific to the `datastore`,

specific Google AppEgine database, they are not available for now

in cubicweb-ctl, but they are available in the instance created.

For more details, please see :ref:`gaecontents` .

Commands to control instances

-----------------------------

* ``start``, starts one or more or all instances

* ``stop``, stops one or more or all instances

* ``restart``, restarts one or more or all instances

* ``status``, returns the status of the instance

Commands to maintain instances

------------------------------

* ``upgrade``, launches the existing instances migration when a new version

  of `CubicWeb` or the cubes installed is available

* ``shell``, opens a migration shell for manual maintenance of the instance

* ``db-dump``, creates a dump of the system database

* ``db-restore``, restores a dump of the system database

* ``db-check``, checks data integrity of an instance. If the automatic correction

  is activated, it is recommanded to create a dump before this operation.

* ``schema-sync``, synchronizes the persistent schema of an instance with

  the application schema. It is recommanded to create a dump before this operation.

Commands to maintain i18n catalogs

----------------------------------

* ``i18ncubicweb``, regenerates messages catalogs of the `CubicWeb` library

* ``i18ncube``, regenerates the messages catalogs of a cube

  This is automatically done while upgrading.

See also chapter :ref:`internationalisation`.

Other commands

--------------

* ``list``, provides a list of the available configuration, cubes

  and instances.

* ``delete``, deletes an instance (configuration files and database)

Create an instance from an existing cube

````````````````````````````````````````

To create an instance from an existing cube, execute the following

command ::

   cubicweb-ctl create <cube_name> <instance_name>

This command will create the configuration files of an instance in

``~/etc/cubicweb.d/<instance_name>``.

The tool ``cubicweb-ctl`` allows you to execute the command ``db-create``

and ``db-init`` when you run ``create`` so that you can complete an

instance creation in a single command.

If you decide not to execut those commands while ``cubicweb-ctl create``,

then you will have to execute them seperately(``cubicweb-ctl db-create``,

``cubicweb-ctl db-init`` ) otherwise your installation will not be complete

and you will not be able to launch your instance.

Creation of an instance from a new cube

```````````````````````````````````````

Create first your new cube cube ::

   cubicweb-ctl newcube <mycube>

This will create a new cube in ``/path/to/forest/cubicweb/cubes/<mycube>``

for a Mercurial forest installation, or in ``/usr/share/cubicweb/cubes``

explained just above.
