ELK Stack

How to Install Elastic Stack (ELK) on Red Hat Enterprise Linux (RHEL)

Sometimes, software just goes together. Linux, the Apache Web server, MySQL, and PHP, the four ingredients of the LAMP stack, which revolutionized data centers and made open source a big deal two decades ago, are probably the most famous example. But there are lots of others.

Here’s another open source software stack you should know about in our present age of cloud and big data: the Elastic Stack, or ELK. Based on Elasticsearch, Logstash and Kibana, ELK is a fully open source solution for searching, analyzing and visualizing data in any format, at any scale.
