No previous knowledge of high-availability systems is needed, though the reader is expected to have at least some degree of familiarity with any spin-off of the Fedora family of Linux distributions, preferably CentOS.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhat You Will Learn\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eInstall a CentOS 7 cluster and network infrastructure\u003c\/li\u003e\n\u003cli\u003eConfigure firewall, networking, and clustering services and settings\u003c\/li\u003e\n\u003cli\u003eSet up and test a HAC (high-availability cluster) to host an Apache web server and a MariaDB database server\u003c\/li\u003e\n\u003cli\u003eMonitor performance and availability\u003c\/li\u003e\n\u003cli\u003eIdentify bottlenecks and troubleshoot issues\u003c\/li\u003e\n\u003cli\u003eImprove performance and ensure high availability\u003c\/li\u003e\n\u003c\/ul\u003e\u003cb\u003eIn Detail\u003c\/b\u003e\u003cp\u003eCentOS 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.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eStarting 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.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eAt 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.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStyle and approach\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eAn easy-to-follow and step-by-step guide with hands-on instructions to set up real-world simple cluster scenarios that will start you on the path to building more complex applications on your own.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Packt Publishing","offers":[{"title":"Default Title","offer_id":47135694815472,"sku":"9781785284342","price":22.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781785284342_p0.jpg?v=1763728199","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781785284342","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
