How to Install Logstash on MXLinux Latest

Logstash is an open-source data processing pipeline tool that helps you collect, transform, and output data from various sources. It is part of the Elastic Stack or ELK stack, which is used for centralized logging.

In this tutorial, we will guide you through the process of installing Logstash on MXLinux Latest, step-by-step.

Prerequisites

Before we start installing Logstash, you need to make sure you have the following:

• A computer running MXLinux Latest with root privileges
• A stable and reliable internet connection

Step 1 – Install Java

Logstash is written in Java, so you need to have Java installed on your system. To check if you already have Java installed, run the following command:

java -version

If it shows a Java version, you can skip this step. If not, you can install Java by running the following command:

sudo apt-get update
sudo apt-get install default-jre -y

Step 2 – Download and Install Logstash

Here are the steps to download and install Logstash from the official Elastic repository:

1. Import the Elastic GPG key into your system:

   sudo rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
   

2. Create a new repository file called elastic.repo:

   sudo nano /etc/yum.repos.d/elastic.repo
   

3. Copy and paste the following content into the file:

   [elastic-7.x]
   name=Elastic repository 7.x
   baseurl=https://artifacts.elastic.co/packages/7.x/yum
   gpgcheck=1
   gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
   enabled=1
   autorefresh=1
   type=rpm-md
   

4. Save and close the file.

5. Update the system and install Logstash package:

   sudo apt-get update
   sudo apt-get install logstash -y
   

6. Once the installation is complete, you can check the Logstash version:

   logstash -version
   

   This should show you the installed version of Logstash.

Step 3 – Configure Logstash

Before we can start using Logstash, we need to configure it to match our requirements. The Logstash configuration file is located at /etc/logstash/conf.d/.

You can create a new configuration file called myconfig.conf by running the following command:

sudo nano /etc/logstash/conf.d/myconfig.conf

Add the following input and output configuration to the file:

input {
  stdin {}
}

output {
  stdout {}
}

This configuration simply takes input from the standard input and outputs it to the standard output. You can change it to match your specific use case.

Step 4 – Start Logstash

You can start Logstash in the foreground by running the following command:

sudo service logstash start

This will start Logstash and show the output on the screen. You can test the configuration by entering some input in the console and hitting enter.

Conclusion

In this tutorial, you learned how to install Logstash on MXLinux Latest and configure it to match your use case. With Logstash, you can easily collect, transform, and output data from various sources.
