h1. Introduction Once Petals ESB is installed through the Debian package, it can be started or stopped with two different ways:
* at system level: the Petals ESB containers are running with a dedicated system user '{{petals}}'. To use in production mode,
* at user level: the Petals ESB containers are running as a process of the user that launches them. To use in a development mode.
...h2. Starting Petals ESB at system level
h3. Automatic start
The Petals ESB package comes with an automatic startup script based on System V ({{initd}}) to automatically launch Petals ESB containers as system services when the host boots.
To start the Petals containers, for example, launch the following command on a Ubuntu box:
{code}
cdeneux@sph-latitude-D630:~$ sudo service petals start
{code}
Two natures of containers are identified:
* the "available containers" that are configured. These containers are to configure into the directory {{/etc/petals-esb/container-available}}. One sub-directory by container.
* and, the "enable containers" that are automatically started. These containers are to configure into the directory {{/etc/petals-esb/container-enable}}. One sub-directory by container.
As "Enable containers" are a subset of "Available containers", we recommend to put the configuration of a container into a sub-directory of {{/etc/petals-esb/container-available}}, and create a symbolic link on this sub-directory into {{/etc/petals-esb/container-enable}} to "enable" it.
{info}It's not possible to automatically start a container in debug mode. Use a manual startup.{info}
{note}Caution: The automatic startup starts all Petals ESB containers declared in the directory {{/etc/petals-esb/container-enable}}. So if you add a new Petals ESB container in the sirectory, and use the command "{{service petals-esb start}}", all other Petals ESB containers will be also started, and as they are already started, errors will occurs.{note}
