How to Install Frab on Elementary OS Latest

Frab is a free and open-source conference management system which helps you to manage and organize conferences, lectures, and workshops. Here is a tutorial on how to install Frab on Elementary OS Latest.

Prerequisites

Before starting the installation process, you must have a few prerequisites in place:

• Elementary OS installed and running
• Access to the command line with root privileges
• A web browser

Step 1: Install dependencies

The first step is to install the dependencies required for Frab to work correctly:

sudo apt-get update
sudo apt-get install build-essential zlib1g-dev libssl-dev libreadline-dev libyaml-dev libxml2-dev libxslt-dev libcurl4-openssl-dev libffi-dev

Step 2: Install Ruby

The next step is to install Ruby, which is the programming language that Frab is built on:

sudo apt-get install ruby-full

Step 3: Install Bundler

Bundler is a tool that manages Ruby dependencies. Install Bundler with the following command:

sudo gem install bundler

Step 4: Download and Install Frab

Download the latest version of Frab from the official website:

wget https://github.com/frab/frab/archive/master.zip

Unzip the archive and move the files to a directory of your choice, for example, /opt/frab:

unzip master.zip
sudo mv frab-master /opt/frab

Change the directory to /opt/frab and install the dependencies using Bundler:

cd /opt/frab
sudo bundle install --without development test

Step 5: Configure the Database

Frab uses a PostgreSQL database to store data. Install PostgreSQL with the following command:

sudo apt-get install postgresql postgresql-contrib

Create a new database user and set the password:

sudo -u postgres createuser -P frab_user

Create a new database and grant permissions to the user:

sudo -u postgres createdb -O frab_user frab_production

Update the database configuration file with the credentials:

sudo nano /opt/frab/config/database.yml

Change the following lines:

  production:
    adapter: postgresql
    encoding: utf8
    database: frab_production
    pool: 5
    username: <%= ENV['FRAB_DATABASE_USERNAME'] %>
    password: <%= ENV['FRAB_DATABASE_PASSWORD'] %>
    host: <%= ENV.fetch('FRAB_DATABASE_HOST', 'localhost') %>

to:

  production:
    adapter: postgresql
    encoding: utf8
    database: frab_production
    pool: 5
    username: frab_user
    password: YOUR_PASSWORD
    host: localhost

Save and close the file.

Step 6: Start the Server

You are now ready to start the server:

cd /opt/frab
RAILS_ENV=production bundle exec rake db:migrate
RAILS_ENV=production bundle exec rake assets:precompile
RAILS_ENV=production bundle exec rails server

The Frab server is running and accessible at http://localhost:3000.
