            <title>Setting Up a Hosted Service and Running in Analysis Mode</title>

            <para>
                A hosted service resides on a shared server and allows
                multiple users to take advantage of Toaster.
            </para>

            <para>
                In a production environment, you might want to have multiple
                local instances of the Toaster Logging Interface running on
                various remote build machines, and have those local instances
                access and use a single web server.
                To do this, you need to do the following:
                <itemizedlist>
                    <listitem><para>
                        Maintain a common SQL database.

                        Set up separate instances of BitBake servers
                        and Toaster Logging Interfaces for each of those
                        separate BitBake servers.

            </para>

            <para>
                The common SQL database allows the Web server to show data from
                all the various BitBake builds.
                Setting the SQL database outside of any

                maintains a separation between the various builds.
                The BitBake servers, the SQL server, and the Web server or
                servers can be run on separate machines.
            </para>

                    <listitem><para><emphasis>Install and Set up the Database Server:</emphasis>
                        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> CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';
     mysql> GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost';
     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:
                        <literallayout class='monospaced'>
     $ cat /opt/bitbake/lib/toaster/toastermain/settings.py

                    <listitem><para><emphasis>Install and Set Up the Web Server:</emphasis>
                        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
     $ a2enmod wsgi

     # the WSGIPythonPath is global
     WSGIPythonPath /opt/bitbake/lib/toaster/

     &lt;/Directory&gt;

        ...
                        </literallayout>
                        You need to collect static media from Toaster and
                        continue configuring Apache to serve that static
                        media:
                        <literallayout class='monospaced'>

                        Synchronize the databases for toaster, and then start
                        up the web server.
                        Here is an example that continues with the assumed

                        You can use any SQL server out of the box.

                        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>
                        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'>

                        In the separately cloned tree for the Database Server,
                        edit the

                        Use the username and password established
                        earlier.

                        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
                        100 Gbytes.

                        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
     $ a2enmod wsgi

                        </literallayout>
                        You need to collect static media from Toaster and
                        continue configuring Apache to serve that static
                        media:
                        <literallayout class='monospaced'>
     $ mkdir /var/www.html/static &amp;&amp; cd /var/www.html/static
