Key Features

Master the concepts of high performance and high availability to eliminate performance bottlenecks
Maximize the uptime of services running in a CentOS 7 cluster
A step-by-step guide that will provide knowledge of methods and approaches to optimize the performance of CentOS clusters

Book Description

CentOS is the enterprise level Linux OS, which is 100% binary compatible to Red Hat Enterprise Linux (RHEL). It acts as a free alternative to RedHat's commercial Linux offering, with only a change in the branding. A high performance cluster consists in a group of computers that work together as one set parallel, hence minimizing or eliminating the downtime of critical services and enhancing the performance of the application.

Starting with the basic principles of clustering, you will learn the necessary steps to install a cluster with two CentOS 7 servers. We will then set up and configure the basic required network infrastructure and clustering services. Further, you will learn how to take a proactive approach to the split-brain issue by configuring the failover and fencing of the cluster as a whole and the quorum of each node individually. Further, we will be setting up HAC and HPC clusters as a web server and a database server. You will also master the art of monitoring performance and availability, identifying bottlenecks, and exploring troubleshooting techniques.

At the end of the book, you'll review performance-tuning techniques for the recently installed cluster, test performance using a payload simulation, and learn the necessary skills to ensure that the systems, and the corresponding resources and services, are being utilized to their best capacity.

What you will learn

Install a CentOS 7 cluster and network infrastructure
Configure firewall, networking, and clustering services and settings
Set up and test a HAC (high-availability cluster) to host an Apache web server and a MariaDB database server
Monitor performance and availability
Identify bottlenecks and troubleshoot issues
Improve performance and ensure high availability

主要特點

掌握高性能和高可用性的概念，消除性能瓶頸

最大化 CentOS 7 集群中運行服務的正常運行時間

提供逐步指南，了解優化 CentOS 集群性能的方法和途徑

書籍描述

CentOS 是企業級 Linux 作業系統，與 Red Hat Enterprise Linux (RHEL) 完全二進制兼容。它作為 RedHat 商業 Linux 提供的免費替代品，只有品牌有所不同。高性能集群是一組計算機作為一個並行集合工作，從而最小化或消除關鍵服務的停機時間，提升應用程序的性能。

從集群的基本原理開始，您將學習安裝兩個 CentOS 7 服務器的集群所需的步驟。然後，我們將設置和配置基本的網絡基礎設施和集群服務。此外，您將學習如何通過配置整個集群的故障轉移和隔離以及每個節點的仲裁，以積極應對分裂腦問題。此外，我們將設置 HAC 和 HPC 集群作為 Web 服務器和數據庫服務器。您還將掌握監控性能和可用性、識別瓶頸和探索故障排除技術的技巧。

在本書結尾，您將回顧最近安裝的集群的性能調優技巧，使用負載模擬測試性能，並學習確保系統及相應資源和服務充分利用的必要技能。

您將學到什麼

安裝 CentOS 7 集群和網絡基礎設施

配置防火牆、網絡和集群服務和設置

設置並測試 HAC（高可用性集群），用於托管 Apache Web 服務器和 MariaDB 數據庫服務器

監控性能和可用性

識別瓶頸並解決問題

提升性能並確保高可用性
