How to Install OSEM on Ubuntu Server Latest

In this tutorial, we will cover the steps to install Open Source Event Manager (OSEM) on Ubuntu Server.

Prerequisites

• A server running Ubuntu 19.04, 18.04 or 16.04
• A user with sudo privileges
• Updated system packages

Step 1: Update the system

Before starting with the installation of OSEM, update your system by running the following command:

sudo apt-get update

sudo apt-get upgrade

Step 2: Install Dependencies

OSEM requires several packages to be installed before starting the installation process. To install them, run the following command:

sudo apt-get install -y build-essential libsqlite3-dev libmysqlclient-dev libpostgresql-dev libsasl2-dev libxml2-dev libxslt-dev libffi-dev libyaml-dev zlib1g-dev

Step 3: Install Git

We will use Git to clone the OSEM repository from Github. To install Git, run:

sudo apt-get install -y git

Step 4: Clone the OSEM Repository

Clone the OSEM repository from Github using the following command:

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

Navigate to the cloned directory by running:

cd osem

Step 5: Install Ruby

OSEM is written in Ruby, and therefore, we need to install Ruby to run OSEM. By default, Ubuntu has Ruby preinstalled. You can confirm the version of Ruby installed on your system by running:

ruby -v

If Ruby is not installed already, run the following command:

sudo apt-get install ruby-full

Step 6: Install Bundler

Bundler is a Ruby gem that manages the applications' dependencies. To install Bundler, run:

sudo gem install bundler

Step 7: Install OSEM Dependencies

OSEM has some dependencies that need to be installed before running the server. Install these dependencies by running:

bundle install

Step 8: Configure the Database

Create a database for OSEM using MySQL or PostgreSQL.

For MySQL, run:

sudo apt-get install mysql-server

mysql -u root -p

CREATE DATABASE osem CHARACTER SET utf8 COLLATE utf8_general_ci;

CREATE USER 'osem'@'localhost' IDENTIFIED BY 'password';

GRANT ALL ON osem.* TO 'osem'@'localhost';

For PostgreSQL, run:

sudo apt-get install postgresql

sudo su - postgres

psql

create database osem;

create user osem with password 'password';

grant all privileges on database osem to osem;

Step 9: Setup Environment Variables

We need to set up some environment variables before running OSEM. Run the following commands to set up environment variables:

export RAILS_ENV=production

export OSEM_SECRET_TOKEN=$(openssl rand -hex 64)

export OSEM_DB_ADAPTER=mysql2 #(For MySQL)

export OSEM_DB_ADAPTER=postgresql #(For PostgreSQL)

export OSEM_DB_DATABASE=osem

export OSEM_DB_USERNAME=osem

export OSEM_DB_PASSWORD=password

Step 10: Run Migrations

To create the database schema, execute the following command:

bundle exec rake db:migrate

Step 11: Start the OSEM Server

Finally, we can start the OSEM server using the following command:

bundle exec rails server -b 0.0.0.0 -e production

You can now access OSEM by visiting http://your_server_ip:3000

Congratulations, you have successfully installed OSEM on Ubuntu Server.
