SSH and SSH Tunnel Instructions

The secure and correct way to communicate with non-public services on a virtual server machine is via ssh tunnel (services like managment console or a database).

To create a simple ssh tunnel from your host machine to the server on the same port number:

ssh -L 9090:localhost:9090 god@kewldomain.com

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.

Server install instructions (Rocky Linux 9) for enthusiastic people who wish to run or train LLaMA models.

Rocky Linux 9 | Chatbot Edition

The following was tested on Google GCP utilizing an a2-highgpu-1g instance and Rocky Linux 9 image.
It has 80GB of RAM, 12 CPU cores, and a single NVIDIA A100 40GB GPU attached.
I also recommand taking 500GB SSD hard drive, it's somewhat more than required, but you might need it.

NOTICE: Make sure you have positive bank balance before trying.

Update the 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).
