Summary
Highlights
The video introduces the Elastic Stack, consisting of Elasticsearch, Logstash, and Kibana, along with Filebeat for shipping logs. It highlights the stack's importance for centralized logging, data visualization, and real-time analysis.
The tutorial outlines the prerequisites, including an AWS account with a running Ubuntu 24.04 EC2 instance, at least two CPU cores, and 4 GB of RAM.
The first step involves installing Java, required for Elastic Stack components. The tutorial details updating the package index, installing the `apt-transport-https` package, installing OpenJDK, and verifying the Java version. It also cover setting the JAVA_HOME environment variable.
The video explains how to install Elasticsearch, the core component for search and analytics. This includes importing the public signing key, adding the Elasticsearch APT repository, updating the package list, and installing the Elasticsearch package.
The tutorial details configuring Elasticsearch to allow external access by modifying the `elasticsearch.yml` file. Changes include setting the network host, discovery seed hosts, and disabling security features (not recommended for production environments).
The video guides through the installation of Logstash, used for processing and forwarding log data to Elasticsearch. The steps include installing, starting, and enabling the Logstash service and checking its status.
The tutorial covers the installation of Kibana, used for data visualization. The steps include installing, starting, and enabling the Kibana service and checking its status.
The video explains how to configure Kibana by modifying the `kibana.yml` file. This includes setting the server port, server host, and elasticsearch.hosts for external access.
The tutorial details the installation of Filebeat, a lightweight shipper used to forward and centralize log data. It includes installing the Filebeat package.
The video describes configuring Filebeat by modifying the `filebeat.yml` file. It include commenting out the elasticsearch output and enabling and configuring the lockstash output.
The tutorial explains further steps to load the index template into Elastic search.
The video guides how to start and enable the Filebeat service. Also explains how to verify that Elasticsearch is receiving data from Filebeat by checking the indexes.
The tutorial describes how to access the Kibana interface via a web browser using the EC2 instance's public IP address and port 5601.
The video concludes by summarizing the steps to install and configure the Elastic Stack with Filebeat and highlighting the value of the Elastic Stack for centralized logging and data analysis.
