Installing ELK Stack (Elasticsearch, Logstash, Kibana) on Ubuntu 22.04

The ELK Stack is a powerful combination of Elasticsearch, Logstash, and Kibana that is used for log analysis and visualization. It provides a centralized platform to collect, store, and analyze logs, making it easier to troubleshoot issues, detect anomalies, and gain insights from your data.

Here are the steps to install ELK Stack on Ubuntu 22.04:

Step 1: Install Java

ELK Stack requires Java, so let's begin by installing it:

$ sudo apt update
$ sudo apt install openjdk-11-jdk

Step 2: Install Elasticsearch

Next, let's install Elasticsearch, which is a distributed search and analytics engine:

$ wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
$ echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee /etc/apt/sources.list.d/elastic-7.x.list
$ sudo apt update
$ sudo apt install elasticsearch

After installation, start and enable Elasticsearch:

$ sudo systemctl start elasticsearch
$ sudo systemctl enable elasticsearch

Step 3: Install Logstash

Logstash is used to collect, transform, and send logs to Elasticsearch. Let's install it:

$ sudo apt install logstash

Start and enable Logstash:

$ sudo systemctl start logstash
$ sudo systemctl enable logstash

Step 4: Install Kibana

Kibana is a web interface for Elasticsearch that provides visualization and management capabilities:

$ sudo apt install kibana

Start and enable Kibana:

$ sudo systemctl start kibana
$ sudo systemctl enable kibana

Step 5: Accessing Kibana

By default, Kibana listens on port 5601. Open your web browser and navigate to http://localhost:5601 to access the Kibana interface.

That's it! You have successfully installed the ELK Stack on Ubuntu 22.04. You can now start collecting and analyzing your logs using Elasticsearch, Logstash, and Kibana.
