How to Install Loki on OpenSUSE Latest

In this tutorial, we will guide you through the installation process of Loki, which is a horizontally-scalable, highly-available, multi-tenant log aggregation system.

Prerequisites

To get started with Loki installation, you must have:

  • An OpenSUSE Latest installed machine
  • Access to the terminal with root privileges

Step 1: Update the system

Before installing any package on your system, it's always a good practice to update the package manager. In OpenSUSE, you can do that by running:

sudo zypper update

Step 2: Add Loki repository to your system

Loki offers official rpm packages for OpenSUSE on their website. To add the Loki repository to your system, run the following command in your terminal:

sudo zypper ar --no-gpgcheck https://download.opensuse.org/repositories/home:/grafana-oss:/loki/openSUSE_Tumbleweed/ loki

This command will add the Loki repository link to your system's repo directory.

Step 3: Install Loki

To install Loki, we will use the zypper package manager. Run the following command in your terminal:

sudo zypper install loki

This command will download and install all the necessary packages required for Loki.

Step 4: Start Loki and enable at boot

Once the installation is complete, you need to start the Loki service and enable it to start automatically at boot time. Run the following commands in your terminal:

sudo systemctl start loki
sudo systemctl enable loki

These commands will start the Loki service and also enable it to start at boot time.

Step 5: Verify installation

To check if Loki is running on your system, you can run the following command:

sudo systemctl status loki

If the service is running correctly, you will see an output message like this:

● loki.service - Grafana Loki
