Setting Up Caddy 2.7.3 on Linux
After installing the caddy
binary, you can configure and launch your Caddy server. The following sections outline key setup steps.
1. Basic Configuration
Caddy uses a configuration file called Caddyfile
. Create this file in your project directory or /etc/caddy/
for system-wide configuration.
Here’s a simple example:
localhost
file_server browse
This configuration sets up a file server on localhost
and enables directory browsing.
2. Starting the Server
Run the following command to start Caddy with your configuration:
sudo caddy run --config /etc/caddy/Caddyfile
You can also use caddy start
to run it as a background process.
3. Automatic HTTPS
One of the standout features of Caddy is its automatic HTTPS provisioning. By default, Caddy will request and install an SSL certificate for your domain using Let’s Encrypt. Ensure that:
- Your domain points to the server’s IP address.
- Port 443 is open for HTTPS traffic.
For example:
example.com
file_server
This configuration enables HTTPS for example.com
with minimal effort.
4. Running Caddy as a Systemd Service
To run Caddy as a service, create a systemd
unit file:
sudo nano /etc/systemd/system/caddy.service
Add the following content:
[Unit]
Description=Caddy Web Server
After=network.target
[Service]ExecStart=/usr/local/bin/caddy run –config /etc/caddy/Caddyfile
Restart=always
User=www-data
Group=www-data
[Install]
WantedBy=multi-user.target
Enable and start the service:
sudo systemctl enable caddy
sudo systemctl start caddy

Caddy’s file server functionality makes it perfect for hosting static websites. Simply point the file_server
directive to the directory containing your HTML, CSS, and JavaScript files.
2. Reverse Proxy
Caddy can act as a reverse proxy for backend services, simplifying load balancing and HTTPS management.
Example configuration:
example.com {
reverse_proxy localhost:8080
}
3. API Gateway
