How to Install Openshift on Arch Linux

Openshift is a free, open-source cloud computing platform for hosting your applications. It allows you to easily deploy and manage diverse applications using a variety of languages, frameworks, and database technologies. In this tutorial, we will guide you on how to install Openshift on Arch Linux.

Prerequisite

Before we start with the installation, ensure that your system is updated to the latest version. To update your system in Arch Linux, use the following command:

sudo pacman -Syu

Step 1: Install Required Dependencies

To install Openshift on Arch Linux, you need to install some dependencies first. Use the following command to install the dependencies:

sudo pacman -S ruby rubygems npm postgresql

Step 2: Install RVM (Ruby Version Manager)

Next, we need to install RVM (Ruby Version Manager), which is required to install and manage different versions of Ruby.

First, we need to install the GnuPG package and add the GnuPG key:

sudo pacman -S gnupg
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

Now, install RVM:

\curl -sSL https://get.rvm.io | bash -s stable

Once the installation is complete, you need to add RVM to your shell's startup files.

Add the following lines at the end of your ~/.zshrc or ~/.bashrc file:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

Step 3: Install OpenShift Origin

Now, we can proceed to install OpenShift Origin. Use the following command to install OpenShift:

gem install rhc openshift-origin-client-tools

To check if the installation is successful, run the following command to verify the installation:

rhc --version

Step 4: Configure PostgreSQL

OpenShift requires a PostgreSQL database to function correctly. To set up and configure PostgreSQL, follow these steps:

1. Install PostgreSQL:

sudo pacman -S postgresql

2. Initialize the PostgreSQL Database:

sudo su - postgres -c "initdb --locale en_US.UTF-8 -D '/var/lib/postgres/data'"

3. Start the PostgreSQL Service:

sudo systemctl start postgresql.service

4. Create a New PostgreSQL User:

sudo -u postgres createuser -s -P openshift

When prompted, enter a password for the new user.

5. Create a New PostgreSQL Database:

sudo -u postgres createdb -O openshift openshift

Step 5: Run OpenShift

Now, we can start OpenShift on Arch Linux with the following command:

sudo systemctl start openshift.service

Once the service is started successfully, you can use OpenShift by entering the following command:

rhc setup

This will prompt you to enter your OpenShift username and password.

Conclusion

That’s it! We have successfully installed OpenShift on Arch Linux. You can now start building and deploying your applications using OpenShift.
