Why deploy ELK on Rocky Linux 9 instead of Elastic Cloud — what you get, what the official docs miss, and what you'll have when done.
Understand the ELK stack deployment architecture on Rocky Linux 9, size your VMs for the workload, and confirm all prerequisites.
Install Elasticsearch on all three nodes on Rocky Linux 9: cluster TLS, data path relocation, system tuning, and cluster verification.
Install Kibana, put it behind an Apache reverse proxy with SSL, configure the Elasticsearch connection with authentication, and verify dashboard access.
Install Logstash, tune the JVM for your available RAM, configure a pipeline that accepts Beats and syslog input, and verify data flows into Elasticsearch.
Install Filebeat on your hosts, configure it to ship system logs to Logstash, work around the 9.x fileset trap, and verify logs flow into Elasticsearch.
Configure ILM policies, index templates, and log pipeline on Rocky Linux 9 — then verify your first logs appear in Kibana.
Know where to look when things break, recognize the most common ELK failure modes, and fix them without spending hours on Stack Overflow.
File paths, ports, essential commands, Ansible variables, and vault variables for the entire ELK stack deployment — all in one place.
