About

n8n can be used to make AI workflows and execute them.

Install nodejs via below as root user:

curl -fsSL https://rpm.nodesource.com/setup_22.x -o nodesource_setup.sh
sudo -E bash nodesource_setup.sh
sudo dnf install -y nodejs
node -v
npm -v

To install N8n on local system we can use npn and install via root user using:

sudo npm install n8n -g

Then we can start n8n service as root user via:

n8n start

Then open http://locahost:5678/ and create account to work with n8n workflows.

Create a new workflow
Add first step "Basic LLM chain". Use "<-" from top left to go back to canvas
Select model and select desired ollama model. If required add a credential with base URL "http://localhost:11434" to connect to local ollama
Add "Convert to file" with "Convert to html" node
Add "Read/Write files to disk" with "Write file to disk"
Give file path. Since we started n8n as root we can write almost anywhere but file will get created with root privileges. Eg /home/user/Desktop/output.html
Save and execute workflow to see query output saved on Desktop in html file
