        <title>Starting Toaster for Local Development</title>

        <para>
            Once you have set up the Yocto Project and installed the
            Toaster system dependencies as described in
            "<link linkend='toaster-manual-start'>Preparing to Use Toaster</link>",
            you are ready to start Toaster.
        </para>

        <para>
            If you want to configure and start your builds using the
            Toaster web interface
            (i.e. "<link linkend='toaster-build-mode'>Build Mode</link>"),
            navigate to the root of your
            <ulink url='&YOCTO_DOCS_DEV_URL;#source-directory'>Source Directory</ulink>
            (e.g. <filename>poky</filename>):
            <literallayout class='monospaced'>
     $ cd poky
            </literallayout>
            Next, start Toaster:
            <literallayout class='monospaced'>
     $ bitbake/bin/toaster
            </literallayout>
            Open your favourite browser and enter the following:
            <literallayout class='monospaced'>
     http://127.0.0.1:8000
            </literallayout>
            If you would rather configure and start your builds
            using the command line
            (i.e. <link linkend='toaster-analysis-mode'>Analysis Mode</link>),
            you can get Toaster to "listen"
            to your builds and collect information about them.
            To do that, navigate to the root of your Source Directory:
            <literallayout class='monospaced'>
     $ cd poky
            </literallayout>
            Once in that directory, source the build environment script:
            <literallayout class='monospaced'>
     $ source oe-init-build-env
            </literallayout>
            Next, from the build directory (e.g.
            <filename>poky/build</filename>), start Toaster using this
            command:
            <literallayout class='monospaced'>
     $ source ../bitbake/bin/toaster
            </literallayout>
            You can now run builds normally.
        </para>

        <para>
            To see the build information provided by Toaster, open your
            favorite browser and enter the following:
            <literallayout class='monospaced'>
     http://127.0.0.1:8000
            </literallayout>
        </para>

    <section id='setting-a-different-port'>
        <title>Setting a Different Port</title>

        <para>
            By default, Toaster starts on port 8000.
            You can use the <filename>WEBPORT</filename> parameter to
            set a different port.
            For example, either of the following commands sets the
            port to "8400":
            <literallayout class='monospaced'>
     $ bitbake/bin/toaster webport=8400
            </literallayout>
            or
            <literallayout class='monospaced'>
     $ source ../bitbake/bin/toaster webport=8400
            </literallayout>
        </para>
    </section>

    <section id='the-directory-for-cloning-layers'>
        <title>The Directory for Cloning Layers</title>

        <para>
            If you are running Toaster in
            <link linkend='toaster-build-mode'>Build Mode</link>,
            Toaster creates a <filename>_toaster_clones</filename>
            directory inside your Source Directory
            (i.e. <filename>poky</filename>).
            For example, suppose you use this command to start Toaster:
            <literallayout class='monospaced'>
     poky/bitbake/bin/toaster
            </literallayout>
            In this example, Toaster creates and uses the
            <filename>poky/_toaster_clones</filename>
            directory to clone any layers needed for your builds.
        </para>

        <para>
            Alternatively, if you would like all of your Toaster related
            files and directories to be in a particular location other than
            the default, you can set the <filename>TOASTER_DIR</filename>
            environment variable, which takes precedence over your current
            working directory.
            Setting this environment variable causes Toaster to create and use
            <filename>$TOASTER_DIR./_toaster_clones</filename>.
        </para>
    </section>

    <section id='toaster-the-build-directory'>
        <title>The Build Directory</title>

        <para>
            If you are running Toaster in
            <link linkend='toaster-build-mode'>Build Mode</link>,
            Toaster creates a build directory within your Source
            Directory (e.g. <filename>poky</filename>).
            For example, suppose you use this command to start Toaster:
            <literallayout class='monospaced'>
     poky/bitbake/bin/toaster
            </literallayout>
            In this example, Toaster creates and uses the
            <filename>poky/build</filename>
            directory to execute the builds.
        </para>

        <para>
            Alternatively, if you would like all of your Toaster related files
            and directories to be in a particular location, you can set
            the <filename>TOASTER_DIR</filename> environment variable,
            which takes precedence over your current working directory.
            Setting this environment variable causes Toaster to use
            <filename>$TOASTER_DIR./build</filename> as the build directory.
        </para>

    <section id='toaster-creating-a-django-super-user'>
        <title>Creating a Django Superuser</title>

        <para>
            Toaster is built on the
            <ulink url='https://www.djangoproject.com/'>Django framework</ulink>.
            Django provides an administration interface you can use
            to edit Toaster configuration parameters.
        </para>

        <para>
            To access the Django administration interface, you must
            create a superuser by following these steps:
            <orderedlist>
                <listitem><para>
                    If you used <filename>virtualenv</filename>, which is
                    recommended, to set up the Toaster system dependencies,
                    you need be sure the virtual environment is activated.
                    To activate this environment, use the following:
                    <literallayout class='monospaced'>
     $ source venv/bin/activate
                    </literallayout>
                    </para></listitem>
                <listitem><para>
                    From the root of your checkout directory, invoke the
                    following command from <filename>manage.py</filename>:
                    <literallayout class='monospaced'>
     $ ./bitbake/lib/toaster/manage.py createsuperuser
                    </literallayout>
                    </para></listitem>
                <listitem><para>
                    Django prompts you for the username, which you need to
                    provide.
                    </para></listitem>
                <listitem><para>
                    Django prompts you for an email address, which is
                    optional.
                    </para></listitem>
                <listitem><para>
                    Django prompts you for a password, which you must provide.
                    </para></listitem>
                <listitem><para>
                    Django prompts you to re-enter your password for verification.
                    </para></listitem>
            </orderedlist>
            After completing these steps, the following confirmation message
            appears:
            <literallayout class='monospaced'>
     Superuser created successfully.
            </literallayout>
        </para>

        <para>
            Creating a superuser allows you to access the Django administration
            interface through a browser.
            The URL for this interface is the same as the URL used for the
            Toaster instance with "/admin" on the end.
            For example, if you are running Toaster locally, use the
            following URL:
            <literallayout class='monospaced'>
     http://127.0.0.1:8000/admin
            </literallayout>
            You can use the Django administration interface to set Toaster
            configuration parameters such as the build directory, layer sources,
            default variable values, and BitBake versions.

        <title>Setting Up a Production Instance of Toaster</title>

        <para>
            You can use a production instance of Toaster to share the
            Toaster instance with remote users, multiple users, or both.
            The production instance is also the setup that can cope with
            heavier loads on the web service.
            Use the instructions in the following sections to set up
            Toaster in
            <link linkend='toaster-build-mode'>Build Mode</link>
            where builds and projects are run,
            viewed, and defined through the Toaster web interface.

                            Alternatively, you can use your operating system's

                        You can use any SQL server out of the box.
                        It is recommended that you use
                        <filename>mysql-server</filename> because it has
                        the advantages of advanced SQL features along with a
                        fast and reliable database.
                        However, setting up <filename>mysql-server</filename>
                        is more complex and might require a Database
                        Administrator to tune it.</para>
                        <para>Another supported database backend is
                        <filename>sqlite3</filename>.
                        With <filename>sqlite3</filename>, you have the
                        advantage of no configuration and an easy installation.
                        However, Toaster still requires direct access to the
                        backend.
                        The <filename>sqlite</filename> backend is also slower
                        as compared to <filename>mysql-server</filename>, and
                        has no transactional support.</para>
                        <para>You should set up proper username and password
                        access on the shared database for everyone that will
                        be using Toaster.
                        You need administrator rights for the root account,
                        which is not the same thing as root access on the
                        machine.
                        Here is an example that installs
                        <filename>mysql-server</filename> and sets up
                        some user accounts and the database.
                        <literallayout class='monospaced'>
     $ apt-get install mysql-server
     $ mysql -u root

                        </literallayout>
                        You need a separate clone of the
                        <ulink url='&YOCTO_DOCS_DEV_URL;#source-repositories'>Source Repositories</ulink>
                        for the Database Server.

     # Create the user under which the builds will run
     $ adduser poky

     # Bring up the administration interface

     # Login with the admin user previously created

     # Go to the BuildEnvironment object in Build Environments and
     # set address to local host, sourcedir to /home/poky, and

     # Go to Home, Bitbake Versions, Add bitbake version;
     # Take version information from: http://git.openembedded.org/bitbake/refs/heads,
     # This example assumes "master" version.

                        You also need to configure the project releases, the

                        You can use any SQL server out of the box.
                        It is recommended that you use
                        <filename>mysql-server</filename> because it has
                        the advantages of advanced SQL features along with a
                        fast and reliable database.
                        However, setting up <filename>mysql-server</filename>
                        is more complex and might require a Database
                        Administrator to tune it.</para>
                        <para>Another supported database backend is
                        <filename>sqlite3</filename>.
                        With <filename>sqlite3</filename>, you have the
                        advantage of no configuration and an easy installation.
                        However, Toaster still requires direct access to the
                        backend.
                        The <filename>sqlite</filename> backend is also slower
                        as compared to <filename>mysql-server</filename>, and
                        has no transactional support.</para>
                        <para>You should set up proper username and password
                        access on the shared database for everyone that will
                        be using Toaster.
                        You need administrator rights for the root account,
                        which is not the same thing as root access on the
                        machine.
                        Here is an example that installs
                        <filename>mysql-server</filename> and sets up
                        some user accounts and the database.
                        <literallayout class='monospaced'>
     $ apt-get install mysql-server
     $ mysql -u root

     mysql> GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost';
     mysql> CREATE DATABASE 'toaster';
                        </literallayout>
                        You need a separate clone of the
                        <ulink url='&YOCTO_DOCS_DEV_URL;#source-repositories'>Source Repositories</ulink>
                        for the Database Server.
                        This clone is only used for getting the latest Toaster
                        files.
                        You can set this up using the following Git command.
                        Be sure to set up the directory outside of any
                        Build Directories.
                        <literallayout class='monospaced'>
     $ git clone git://git.yoctoproject.org/poky
                        </literallayout>
                        In the separately cloned tree for the Database Server,
                        edit the
                        <filename>bitbake/lib/toaster/toastermain/settings.py</filename>
                        file so that the <filename>DATABASES</filename> value
                        points to the previously created database server.
                        Use the username and password established
                        earlier.
                        Here is an example:

                        The interface asks you if you want to create a
                        superuser.
                        Do not skip this step.
                        You will use the superuser account to access the

                        You need to create three directories for storing
                        build artifacts, downloading sources, and running
                        builds.
                        All three directories need to be writable by
                        the user, which is "poky" in this example.
                        The build artifacts directory needs to readable by the
                        apache user.
                        You also need free disk space in the range of

                        For a production environment, it is recommended that
                        you install and set up a front-end web server.
                        This server allows for load balancing and
                        multi-threading over Toaster and
                        <ulink url='https://docs.djangoproject.com/en/1.7/howto/deployment/wsgi/'><filename>django</filename> WSGI</ulink>.
                        Here is an example that uses Apache web server:
                        <literallayout class='monospaced'>
     $ apt-get install apache2 libapache2-mod-wsgi

                        You need to collect static media from Toaster and
                        continue configuring Apache to serve that static
                        media:

                        You need to run the build control manager.
                        You can do this as shown in the following example:
                        <literallayout class='monospaced'>
     # as the "poky" user, start the runbuilds command in a loop (or put it in crontab!)

     # open up the web interface
     $ xdg-open http://[server-address]/toastergui/
                        </literallayout>
                        It is suggested that you enable build control by
                        setting <filename>runbuilds</filename> in the
                        <filename>crontab</filename> as follows:

                        Once the Apache server is running, connect to it with

            <title>Building a Specific Recipe Given Multiple Versions</title>

            <para>
                Occasionally, a layer might provide more than one version of
                the same recipe.
                For example, the <filename>openembedded-core</filename> layer
                provides two versions of the <filename>bash</filename> recipe
                (i.e. 3.2.48 and 4.3.30-r0) and two versions of the
                <filename>which</filename> recipe (i.e. 2.21 and 2.18).
                The following figure shows this exact scenario:
                <imagedata fileref="figures/bash-oecore.png" align="center" width="9in" depth="6in" />
            </para>

            <para>
                By default, the OpenEmbedded build system builds one of the
                two recipes.
                For the <filename>bash</filename> case, version 4.3.30-r0 is
                built by default.
                Unfortunately, Toaster as it exists, is not able to override
                the default recipe version.
                If you would like to build bash 3.2.48, you need to set the
                <ulink url='&YOCTO_DOCS_REF_URL;#var-PREFERRED_VERSION'><filename>PREFERRED_VERSION</filename></ulink>
                variable.
                You can do so from Toaster, using the "Add variable" form,
                which is available in the "BitBake variables" page of the
                project configuration section as shown in the following screen:
                <imagedata fileref="figures/add-variable.png" align="center" width="9in" depth="6in" />
            </para>

            <para>
                To specify <filename>bash</filename> 3.2.48 as the version to build,
                enter "PREFERRED_VERSION_bash" in the "Variable" field, and "3.2.48"
                in the "Value" field.
                Next, click the "Add variable" button:
                <imagedata fileref="figures/set-variable.png" align="center" width="9in" depth="6in" />
            </para>

            <para>
                After clicking the "Add variable" button, the settings for
                <filename>PREFERRED_VERSION</filename> are added to the bottom
                of the BitBake variables list.
                With these settings, the OpenEmbedded build system builds the
                desired version of the recipe rather than the default version:
                <imagedata fileref="figures/variable-added.png" align="center" width="9in" depth="6in" />
            </para>
