[Unit]
Description=Caddy Web Server
After=network.target
[Service]
User=caddy
Group=caddy

Understanding the Caddyfile
The Caddyfile is where you define how your server behaves. It uses a simple syntax that makes it easy to configure various aspects of your web server.
Creating Your First Site
The next step is to create a site that Caddy will serve. Follow these instructions:
-
- Create a directory for your site’s files:
sudo mkdir -p /var/www/example.com/html-
- Set permissions for this directory:
sudo chown -R caddy:caddy /var/www/example.com/html-
- Create an index.html file as a test page:
echo '<!doctype html><html><head><title>Hello World</title></head><body><h1>Hello, World!</h1></body></html>' | sudo tee /var/www/example.com/html/index.html-
- Edit the Caddyfile to serve your site:
sudo nano /etc/caddy/CaddyfileAdd the following configuration (replace example.com with your domain):
example.com {
root * /var/www/example.com/html
file_server
}-
- Validate your configuration to check for errors:
caddy validate --config /etc/caddy/Caddyfile-
- If validation passes, restart Caddy to apply changes:
sudo systemctl restart caddy- Your website should now be accessible via your browser at
http://example.com.
Testing Your Installation
Accessing Your Website
You can access your newly created site by navigating to http://example.com in your web browser. If everything is set up correctly, you should see “Hello, World!” displayed.
Troubleshooting Common Issues
If you encounter issues accessing your site, consider the following troubleshooting steps:
- Caddy Service Status: Check if the Caddy service is running properly by executing:
sudo systemctl status caddyLook for any error messages in the output.
- Curl Test: Use curl to test if Caddy is responding:
curl http://localhost:80You should receive a response with “Hello, World!” if everything is configured correctly.
- Caddy Logs: Check logs for additional error messages:
sud journalctl -u caddy --no-pager | tail -n 50This command will show you the last 50 lines of logs related to the Caddy service.
- Cors Issues:If you’re using a domain name, ensure DNS records are pointing correctly to your server’s IP address.
Advanced Configuration Options
Enabling HTTPS with Automatic Certificates
Caddy automatically provisions HTTPS certificates using Let’s Encrypt when you specify a domain name in your configuration. Ensure that your domain points to your server’s IP address before enabling HTTPS.
Add this line in your existing site block in the Caddyfile:
{
auto_https on
}Setting Up Reverse Proxy (Optional)
If you want to use Caddy as a reverse proxy for another application running on your server, you can modify your Caddyfile like this:
example.com {
reverse_proxy localhost:8080
