Rocky Linux 8 - Web Application Server Installation Guide

Notice

This cheatsheet assumes the user is knowledgeable about bare installations of virtual private servers on cloud providers and is looking for quick but comprehensive instructions.

Some trivial commands might be missed or skipped.
However, this document can also work as quick tutorial for newcomers to the RHEL eco-system.

Also, I would like to promote Rocky Linux as a solid alternative for enterprise systems. Machines with Rocky Linux are provided by DigitalOcean a great and super stable cloud provider I've been using for years. All the following servers/services can be installed and run stable on a 1CPU/2GB/50GB, 2CPU/2GB/50GB or 2CPU/4GB/50GB droplets (choose by your load).

Postgres (running on boot)

docker run -d --name postgres --restart always \
-e POSTGRES_USER=postgres \
-e POSTGRES_PASSWORD=mysecretpassword \
-e POSTGRES_DB=mydatabase \
-p 5432:5432 \
postgres:13-alpine
