Hands-On Linux for Architects

Overview of this book

It is very important to understand the ?exibility of an infrastructure when designing an efficient environment. In this book, you will cover everything from Linux components and functionalities through to hardware and software support, which will help you to implement and tune effective Linux-based solutions. This book gets started with an overview of Linux design methodology. Next, you will focus on the core concepts of designing a solution. As you progress, you will gain insights into the kinds of decisions you need to make when deploying a high-performance solution using Gluster File System (GlusterFS). In the next set of chapters, the book will guide you through the technique of using Kubernetes as an orchestrator for deploying and managing containerized applications. In addition to this, you will learn how to apply and configure Kubernetes for your NGINX application. You’ll then learn how to implement an ELK stack, which is composed of Elasticsearch, Logstash, and Kibana. In the concluding chapters, you will focus on installing and configuring a Saltstack solution to manage different Linux distributions, and explore a variety of design best practices. By the end of this book, you will be well-versed with designing a high-performing computing environment for complex applications to run on. By the end of the book, you will have delved inside the most detailed technical conditions of designing a solution, and you will have also dissected every aspect in detail in order to implement and tune open source Linux-based solutions

Chapter 12: Using Elasticsearch, Logstash, and Kibana to Manage Logs

  1. Elasticsearch can be installed through the package manager.
  2. This is done through parted.
  3. Adding the UUID of the disks to /etc/fstab.
  4. /etc/elasticsearch/elasticsearch.yml
  5. This gives the name to the cluster, the name should be consistent across nodes so each join the same cluster.
  1. The number is dictated by (N/2)+1.
  2. By using the same cluster.name setting, the second node will join to the same cluster.
  3. Add the repo, install through yum, partition the disk for logstash.
  4. This is a storage location where logstash will persistently store queues in the scenario of a crash.
  5. A coordinating node is an Elasticsearch node that does not accept inputs, does not store data or takes part in master/slave elections.
  6. Beats are the lightweight data shippers from Elastic.co.
  7. Filebeat function is to collect logs from sources like...
