Loki on Kali Linux

How to Install Loki on Kali Linux

Loki is a horizontally scalable, highly available, multi-tenant log storage system from Grafana. This tutorial will guide you through the process of installing Loki on Kali Linux.

Prerequisites

Before proceeding with the installation, you need to make sure that you have the following prerequisites in place:

Kali Linux installed on your machine
Internet connectivity for downloading Loki and its dependencies
A user account with sudo privileges

Step 1: Install Dependencies

Loki requires a few dependencies that you need to install first. Open a terminal and run the following commands:

sudo apt-get update
sudo apt-get install -y docker.io docker-compose unzip
sudo usermod -aG docker $USER

The first command updates the package list, the second command installs Docker, Docker Compose and unzip packages, and the third command adds your user account to the docker group.

Step 2: Download and Extract Loki

Next, download the latest version of Loki from the Grafana website with the following command:

wget https://github.com/grafana/loki/releases/latest/download/loki-linux-amd64.zip

Once the download is complete, extract the Loki binary to /usr/local/bin with the following command:

sudo unzip loki-linux-amd64.zip -d /usr/local/bin/

Step 3: Create Loki Configuration File

Create a configuration file for Loki with the following command:

sudo nano /etc/loki/local-config.yaml

Copy and paste the following configuration into the file:

auth_enabled: false
server:
  http_listen_port: 3100
storage_config:
  boltdb:
    directory: /tmp/loki/index
  filesystem:
    directory: /tmp/loki/chunks
limits_config:
  enforce_metric_name: false
  reject_old_samples: true
  reject_old_samples_max_age: 168h
chunk_store_config:
  max_look_back_period: 0s
table_manager:
  retention_deletes_enabled: false
  retention_period: 0s

Save and close the file by pressing Ctrl+X and then Y.

Step 4: Start Loki

Start Loki using Docker Compose with the following command:

docker-compose up -d

This command starts Loki in the background.

Step 5: Verify Installation

Check if Loki is running on your system by opening a web browser and navigating to http://localhost:3100/metrics. If everything is working correctly, you should see a page displaying various system metrics.

Congratulations! You have successfully installed and configured Loki on Kali Linux. You can now use it to store and query your logs.
