Installing Kibana on Ubuntu 20.04

Kibana is an open-source analytics and visualization platform designed to work with Elasticsearch. It allows you to explore, analyze, and visualize data stored in Elasticsearch indices. Kibana provides powerful features such as real-time dashboards, data exploration, machine learning capabilities, and more, making it a popular choice for monitoring and analyzing data.

Step 1: Update System Packages

Before installing any new software, it is recommended to update the system packages to the latest versions:

sudo apt update
sudo apt upgrade -y

Step 2: Install Java Development Kit (JDK)

Kibana requires Java to run. Install OpenJDK using the following commands:

sudo apt install openjdk-11-jdk

Step 3: Install Kibana

Download the Kibana package using one of the following methods:

wget https://artifacts.elastic.co/downloads/kibana/kibana-7.15.1-linux-x86_64.tar.gz

curl -L -O https://artifacts.elastic.co/downloads/kibana/kibana-7.15.1-linux-x86_64.tar.gz

• Option 1: Download the .tar.gz file from the official Elastic website
• Option 2: Use curl command to download the package

Extract the downloaded package:

tar xzf kibana-7.15.1-linux-x86_64.tar.gz

Move the extracted directory to /opt:

sudo mv kibana-7.15.1-linux-x86_64 /opt/kibana

Step 4: Configure Kibana

Open the Kibana configuration file using a text editor:

sudo nano /opt/kibana/config/kibana.yml

Find the following line:

# server.host: "localhost"

Uncomment it and replace "localhost" with the server's IP address or hostname:

server.host: "your_server_ip_or_hostname"

Save the file and exit the text editor.

Step 5: Start and Enable Kibana

Start the Kibana service:

sudo systemctl start kibana

Enable the Kibana service to start on boot:

sudo systemctl enable kibana

Step 6: Access Kibana

Open a web browser and enter "http://your_server_ip_or_hostname:5601" in the address bar. You should see the Kibana login page.

Log in to Kibana using the default username and password: username = "elastic", password = "password". It is highly recommended to change the default password after the initial login.

That's it! You have successfully installed and configured Kibana on Ubuntu 20.04.
