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.
Before proceeding with the installation, make sure that the following prerequisites are met:
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
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.
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.
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
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
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.
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.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
