How to Install Fluentd on Linux Mint

This tutorial will guide you through the process of installing Fluentd on the latest version of Linux Mint. Fluentd is an open-source log collector that allows you to unify data collection and ingestion from different sources. It supports various input and output plugins, making it suitable for different use cases.

Prerequisites

• Linux Mint Operating System
• A user account with sudo privileges
• Basic knowledge of Linux command-line interface

Step 1: Install Required Dependencies

Before installing Fluentd, we need to install some dependencies required by Fluentd. To do this, open the terminal by pressing Ctrl+Alt+T and run the following command:

sudo apt update
sudo apt install -y ruby ruby-dev build-essential

This command will update the package list and install Ruby, Ruby development headers, and build-essential package.

Step 2: Install Fluentd

We can install Fluentd by running the following command:

sudo gem install fluentd -v 1.13.3

This command will install Fluentd version 1.13.3. You can check the latest version of Fluentd from their official website.

Step 3: Verify Fluentd Installation

After the installation is completed, we can verify it by running the following command:

Step 4: Create a Fluentd Configuration File

Create a new configuration file for Fluentd by running the following command:

sudo nano /etc/fluentd/fluent.conf

This command will open a new file in nano editor. Copy and paste the following configuration to this file:

<source>
  @type forward
  port 24224
  bind 0.0.0.0
</source>

<match **>
  @type stdout

This configuration sets up a source that listens on port 24224 and binds to 0.0.0.0. The match directive sends all messages to stdout plugin in JSON format.
