Linux binary packages

Supported distributions

Binary installation packages are available for the following Linux distributions:

  1. Fedora 22 and higher
    FrePPLe is included in the official repositories.
    ../_images/fedorainstall.png
  2. Ubuntu LTS
    A 64-bit binary package for Ubuntu 14 is available.

Other Linux distributions aren’t really a problem, but you’ll need to build the frePPLe package from the source .deb or .rpm files, as described on the next page. The build process is completely standardized.

Installation and configuration

The binary package installs the solver engine executables as well as the user interface. The user interface is installed as a WSGI application deployed on the Apache web server with the mod_wsgi module.

Here are the steps to get a fully working environment.

  1. Install and tune the PostgreSQL database

    Install postgreSQL 9.0 or higher, the world’s most advanced open source database.

    FrePPLe assumes that the database uses UTF-8 encoding.

    FrePPLe needs the following settings for its database connections. If these values are configured as default for the database (in the file postgresql.conf) or the database role (using the ‘alter role’ command), a small performance optimization is achieved:

    client_encoding: 'UTF8',
    default_transaction_isolation: 'read committed',
    timezone: 'UTC' when USE_TZ is True, value of TIME_ZONE otherwise.
    

    See the Django documentation at http://docs.djangoproject.com/en/dev/ref/databases/ for more details.

  2. Tune the database

    The default installation of PostgreSQL is not configured right for intensive use. We highly recommend using the pgtune utility (or its online version at http://pgtune.leopard.in.ua/) to optimize the configuration for your hardware.

  3. Create the database and database user

    A database needs to be created for the default database, and one for each of the what-if scenarios you want to configure.

    The same user is normally used as the owner of these databases.

    The typical SQL statements are shown below. Replace USR, PWD, DB with the suitable values.

    create user USR with password 'PWD';
    create database DB encoding 'utf-8' owner USR;
    
  4. Install Python3 and pip3

    You’ll need to install the Python 3.4 or higher and ensure the pip3 command is available. Most Linux distributions provide python2 by default, and you’ll need python3 in parallel with it.

    On RPM based distributions:

    yum install python3 python3-pip
    

    On Debian based distributions:

    apt-get install python3 python3-pip
    
  5. Install the Python modules

    The python3 modules used by frePPLe are listed in the file “requirements.txt”. You can download it from https://raw.githubusercontent.com/frepple/frepple/3.0/contrib/django/requirements.txt (make sure to replace 3.0 with the appropriate version number!)

    Alternatively you can create the file yourself with the following content:

    CherryPy >= 3.2.2
    djangorestframework >= 3.3.1
    djangorestframework-bulk >= 0.2.1
    djangorestframework-filters >= 0.6.0
    et-xmlfile >= 1.0.0
    html5lib >= 0.999
    jdcal >= 1.0
    Markdown >= 2.6.4
    openpyxl >= 2.3.0-b2
    https://github.com/frePPLe/django/tarball/frepple_3.0
    

    Next, install these modules with a pip3 command:

    pip3 install -r requirements.txt
    
  6. Install the frepple binary package

    On Fedora:

    yum install frepple
    

    On Debian based distributions:

    dpkg -i frepple_*.deb
    apt-get -f -y -q install
    

    On RHEL:

    yum --nogpgcheck localinstall  *.rpm
    
  7. Configure frePPLe

    The previous step installed a number of configuration files, which you now need to review and edit:

    1. /etc/frepple/djangosettings.py
      Edit the “TIMEZONE” variable to your local setting.
      Edit the “DATABASES” with your database parameters.
      Change “SECRET_KEY” to some arbitrary value - important for security reasons.
      Optionally, you can define custom attributes in this file: see below.
    2. /etc/frepple/license.xml
      No license file is required for the Community Edition.
      If you are using the Enterprise Edition, replace this file with the
      license file you received from us.
    3. /etc/frepple/init.xml
      For a standard deployment this file doesn’t need modification.
      Comment out the lines loading modules you are not using for a small
      performance improvement.
    4. /etc/httpd/conf.d/z_frepple.conf
      For a standard deployment this file doesn’t need modification.
      It only needs review if you have specific requirements for the setup of
      the Apache web server.
  8. Optionally, define custom attributes

    It is pretty common to add customized attributes on items, locations, operations, etc to reflect the specifics of your business. They can be edited in the property ATTRIBUTES in the file /etc/frepple/djangosettings.py.

    ATTRIBUTES = [
      ('freppledb.input.models.Item', [
        ('attribute1', ugettext('attribute_1'), 'string'),
        ('attribute2', ugettext('attribute_2'), 'boolean'),
        ('attribute3', ugettext('attribute_3'), 'date'),
        ('attribute4', ugettext('attribute_4'), 'datetime'),
        ('attribute5', ugettext('attribute_5'), 'duration'),
        ('attribute6', ugettext('attribute_6'), 'number'),
        ('attribute7', ugettext('attribute_7'), 'integer'),
        ]),
      ('freppledb.input.models.Operation', [
        ('attribute1', ugettext('attribute_1'), 'string'),
        ])
      ]
    

    After editing the file, a script needs to be executed to generate a migration script for the database schema:

    frepplectl makemigrations
    

    Attributes can be added, changed and deleted at any later time as well, but it’s most convenient to define them upfront before the database schema is created in the next step. When you later edit attributes you need to run the following commands to apply the changes to the database schema:

    frepplectl makemigrations
    frepplectl migrate
    
  9. Create the database schema

    Your database is still empty now. The command below will create all objects in the database schema and load some standard parameters.

    frepplectl migrate
    
  10. Optionally, load the demo dataset

    On a first installation, you may choose to install the demo dataset.

    frepplectl loaddata demo
    
  11. Update apache web server (Ubuntu only)

On Ubuntu the following statements are required to complete the deployment on the Apache web server.

sudo a2enmod expires
sudo a2enmod wsgi
sudo a2enmod ssl
sudo a2ensite default-ssl
sudo a2ensite frepple
sudo service apache2 restart
  1. Verify the installation

    If all went well you can now point your browser to http://localhost.

    An administrative user account is created by default: admin, with password admin.

    Try the following as a mini-test of the installation:

    1. Open the screen “input/demand” to see demand inputs.
    2. Open the screen “admin/execute” and generate a plan.
    3. Use the same “admin/execute” screen to copy the default data in a new scenario.
    4. Open the screen “output/resource report” to see the planned load on the resources.

    If these steps all give the expected results, you’re up and running!

Tip

For security reasons it is recommended to change the password of the admin user. Until it is changed, a message is displayed on the login page.
