Installing Loki on Fedora Server

Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system inspired by Prometheus. In this tutorial, we will guide you on how to install Loki on Fedora Server Latest.

Prerequisites

Before we start, ensure that the following prerequisites are met:

• You have root access to the Fedora Server
• A working internet connection
• Docker and Docker Compose are installed on your Fedora Server. If not, you can install them using the following command:

sudo dnf install docker docker-compose

Step 1: Create a directory for Loki

We need to create a directory where we can store the Loki configuration file and data.

sudo mkdir -p /etc/loki /var/lib/loki

Step 2: Download Loki docker-compose file

Download the Loki docker-compose file from the official GitHub repository.

sudo curl -L https://raw.githubusercontent.com/grafana/loki/main/production/docker-compose.yaml -o /etc/loki/docker-compose.yaml

Step 3: Adjust Loki configuration

Open the /etc/loki/docker-compose.yaml file with your preferred text editor and adjust the following settings:

Replace 127.0.0.1 in the loki service section under command: with the IP address of the machine that will run the Loki service.

      command:
        - "-config.file=/etc/loki/local-config.yaml"
        - "-target=127.0.0.1:9090"

Step 4: Start Loki

You can start Loki by running the following command:

sudo docker-compose -f /etc/loki/docker-compose.yaml up -d

Step 5: Verify Loki installation

To verify that Loki is running correctly, open http://<ip address of the machine running Loki>:3100/metrics in your web browser. You should see a page with Prometheus-style metrics.

Congratulations! You have successfully installed Loki on Fedora Server Latest. You can now start configuring the tool to suit your needs.
