# ---------------- FIREWALL STEPS ----------------

# Check if firewalld is installed and running
sudo systemctl status firewalld

# If it's not running, you can start and enable it
sudo systemctl start firewalld
sudo systemctl enable firewalld

# Add a rule to allow traffic on port 6006. Port 6006 is the default port that storybook runs on.
sudo firewall-cmd --permanent --add-port=6006/tcp

# Reload the firewall for the changes to take effect
sudo firewall-cmd --reload

# Check the list of allowed ports
sudo firewall-cmd --list-ports

# ---------------- NGINX STEPS ----------------

# Install Nginx (if not already installed)
sudo yum install nginx

# Start and enable Nginx
sudo systemctl start nginx
sudo systemctl enable nginx

# Copy your storybook-static directory to a location that Nginx can serve from.
# The default web root directory for Nginx is /usr/share/nginx/html.
sudo cp -r /path/to/storybook-static /usr/share/nginx/html/

# Adjust file permissions if needed to ensure that Nginx can read the files
sudo chown -R nginx:nginx /usr/share/nginx/html/storybook-static

# Put the following server block in /etc/nginx/conf.d/storybook.conf
server {
    listen 6006;
    server_name your_domain.com;

    location / {
        root /usr/share/nginx/html/storybook-static;
        index index.html;
    }
}

# Test the Nginx configuration for syntax errors
sudo nginx -t

# If there are no errors, reload Nginx to apply the changes
sudo systemctl reload nginx
