How to Install OSEM on Fedora Server

OSEM is an event management platform, which is based on Ruby on Rails. It is used to organize conferences and events online. In this tutorial, we will see how to install OSEM on Fedora Server.

Prerequisites

Before proceeding with the installation, make sure that the following prerequisites are met:

• You have a Fedora Server machine set up with root access.
• You have a basic understanding of the command line.

Step 1: Install Dependencies

OSEM requires some dependencies to be installed on the system. To install them, run the following command:

sudo dnf install git gcc ruby rubygem-bundler rubygem-rake libxml2-devel libxslt-devel libffi-devel sqlite-devel nodejs postgresql-devel

Step 2: Clone OSEM Repository

To clone the OSEM repository, run the following command:

git clone https://github.com/openSUSE/osem.git

This will clone the OSEM repository to the current directory.

Step 3: Install Gems

Once the repository is cloned, navigate to the osem directory and run the following command to install the required gems:

bundle install

This command will install all the necessary gems required for running OSEM.

Step 4: Configure Database

OSEM requires a database to store event and user information. For this tutorial, we will use PostgreSQL. To install PostgreSQL, run the following command:

sudo dnf install postgresql-server postgresql-contrib

Next, initialize the PostgreSQL database:

sudo postgresql-setup initdb

Start the PostgreSQL service and enable it at startup:

sudo systemctl start postgresql
sudo systemctl enable postgresql

Create a new PostgreSQL user and database for OSEM:

sudo su - postgres
createuser -P osem
createdb -O osem osem_development

Update the config/database.yml file with the new database details.

development:
  adapter: postgresql
  database: osem_development
  username: osem
  password: <password>
  host: localhost
  port: 5432

Step 5: Initialize Database

To create tables in the database and initialize the database with seed data, run the following command:

bundle exec rake db:create db:migrate db:seed

Step 6: Start OSEM

Finally, start the OSEM server by running the following command:

bundle exec rails server

This will start the OSEM server on port 3000. To access OSEM, open a web browser and go to http://<server-ip>:3000.

Conclusion

In this tutorial, we installed OSEM on Fedora Server by installing the necessary dependencies, cloning the repository, installing gems, configuring the database, initializing the database, and starting the OSEM server. You can now use OSEM to organize your events and conferences online.
