How to Install Frab on OpenSUSE Latest

Frab is an open-source conference management system developed with Ruby on Rails. In this tutorial, we are going to walk through the installation process of Frab on OpenSUSE Latest.

Prerequisites

Before we can start the installation, make sure that OpenSUSE Latest is installed, and you have root or sudo access to the server.

You'll also need to have the following packages installed on your system:

• Ruby (version 2.0 or higher)
• PostgreSQL
• Node.js

Step 1: Install Required Packages

Open the terminal and login with your root or sudo account. Then, run the following commands to install Ruby, PostgreSQL, and Node.js:

zypper install ruby postgresql postgresql-server nodejs

Step 2: Install Frab

Download Frab by running the following command:

git clone https://github.com/frab/frab.git

Next, move to the newly created frab directory:

cd frab

Now, we need to install the required Ruby gems. Run the following command:

bundle install --path vendor/bundle

This will install all the required gems in the vendor/bundle directory.

Step 3: Configure Database

Start the PostgreSQL service and login as the postgres user:

systemctl start postgresql
sudo -i -u postgres

Create a new PostgreSQL user for Frab:

createuser -P frab

Enter a secure password for the user when prompted.

Create a new database for Frab:

createdb -O frab frab_production

Exit the Postgres shell by typing exit.

Initialize the database tables by running the following command:

bundle exec rake db:migrate RAILS_ENV=production

Step 4: Configure Frab

Frab configuration is done through environment variables. Create a new file called local_env.yml in the config directory:

cd config
cp example.env.yml local_env.yml

Open the local_env.yml file and configure the following environment variables:

RAILS_ENV: "production"
SECRET_KEY_BASE: "<use rake secret to generate a secure key>"
DATABASE_URL: "postgres://frab:<password>@localhost/frab_production"
FRAB_ADMIN_PASSWORD: "<enter a secure password for the admin user>"

Save and exit the file.

Step 5: Start Frab

Start Frab using the following command:

bin/rails server -e production

Now, open your web browser and navigate to http://localhost:3000. You should see the Frab login page.

Use the admin user account credentials you specified in Step 4 to log in.

That's it! You've successfully installed and configured Frab on OpenSUSE Latest.
