Ollama

Ollama is one of the tools that allows you to run large language models locally. There are other tools like Unsloth Studio, llama.cpp, LM Studio, but Ollama is the simplest.

Installation 
curl -fsSL https://ollama.com/install.sh | sh

By default, running the installation script will attempt to create a user ollama and systemd unit file to run the service when the machine starts.

Fedora 27 comes with Selinux enforced security policy by default this is OK for system or apps where you required a high security level, but for my case to serve a static blog and run a couple of services like OpenSSH and Nginx is ok to set the security policy on permissive mode.

changing the policy can be done via command or setup in permanent way on the selinux config in /etc/selinux/config
