Understanding why modern teams chose containers over bare-metal deployments
If you're running a home server or any Linux machine that's accessible over the internet, password authentication is a ticking time bomb. Automated bots are constantly scanning for SSH servers and attempting brute-force attacks. The solution? SSH key...
If you've tried changing the SSH port on Ubuntu 24.04 and it didn't work, you're not alone. Ubuntu 24.04 handles SSH differently than older versions, and the usual method of editing the config file won't work by itself. In this guide, I'll show you t...
Introduction If you're running a home server and want to access it remotely, you've probably faced this frustrating problem: your ISP keeps changing your public IP address. Every time your router restarts or the IP lease expires, you lose access to y...
Kibana is a powerful visualization tool that integrates with Elasticsearch, offering insights into your data. This guide will help you install the latest versions of Elasticsearch and Kibana on Rocky Linux from scratch.
Start by updating your system to ensure all packages are up-to-date. Open a terminal and run the following command:
sudo dnf update -y
Elasticsearch requires Java to run. Install OpenJDK using the following command:
sudo dnf install java-11-openjdk-devel -y
Verify the Java installation:
java -version
You should see output confirming Java 11 is installed.
To install Elasticsearch, you need to add its official repository. First, import the Elasticsearch GPG key:
sudo rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
Then, create a repository file for Elasticsearch:
sudo tee /etc/yum.repos.d/elasticsearch.repo <<EOF
[elasticsearch-8.x]
name=Elasticsearch repository for 8.x packages
baseurl=https://artifacts.elastic.co/packages/8.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md
EOF
Now that the repository is configured, install the latest Elasticsearch:
sudo dnf install elasticsearch -y
Enable and start the Elasticsearch service:
sudo systemctl enable --now elasticsearch
Verify that Elasticsearch is running:
sudo systemctl status elasticsearch
Next, install Kibana using the following command:
sudo dnf install kibana -y
Once Kibana is installed, configure it by editing the kibana.yml configuration file:
sudo nano /etc/kibana/kibana.yml
Update the following lines:
server.port: 5601
server.host: "localhost"
elasticsearch.hosts: ["http://localhost:9200"]
This configuration sets Kibana to run on port 5601 and connects it to Elasticsearch.
Start and enable the Kibana service:
sudo systemctl enable --now kibana
Verify that Kibana is running:
sudo systemctl status kibana
Kibana should now be accessible at http://localhost:5601. If you are running Kibana on a remote server, replace localhost with your server’s IP address.
If you want to access Kibana from other machines, you need to open port 5601 in the firewall:
sudo firewall-cmd --add-port=5601/tcp --permanent
sudo firewall-cmd --reload
You’ve successfully installed the latest versions of Elasticsearch and Kibana on Rocky Linux. Kibana is now ready for use, allowing you to visualize your Elasticsearch data. Be sure to secure your setup if your instances are accessible over a network, especially for production environments.
