How to Install Caddy Web Server on Rocky Linux 10

---

Caddy is a modern, open-source web server written in Go. It features automatic HTTPS, robust performance, and ease of configuration. Caddy is especially popular for developers and sysadmins looking to simplify TLS and reverse proxy setups.

Prerequisites

---

• Rocky Linux 10 system with root or sudo access
• Basic knowledge of command line operations

Update System Packages

---

Ensure your system is fully up to date before proceeding.

dnf update -y

Install DNF COPR Plugin

---

The COPR plugin is required to enable third-party repositories like the one used for Caddy.

dnf install dnf-plugins-core -y

Enable the Caddy Repository

---

Enable the official Caddy COPR repository to allow package installation.

dnf copr enable @caddy/caddy -y

Install Caddy Web Server

---

Once the repository is enabled, install the Caddy package.

dnf install caddy -y

Start and Enable Caddy

---

Start the Caddy service and enable it to start automatically on boot.

systemctl start caddy
systemctl enable caddy

Configure the Firewall

---

Allow HTTP and HTTPS traffic through the firewall to ensure Caddy can serve content.

firewall-cmd --add-service=http --permanent
firewall-cmd --add-service=https --permanent
firewall-cmd --reload

Verify the Installation

Check if Caddy is installed and running correctly.

After installation, Caddy should be serving content on your server’s IP address.

Open a web browser and navigate to:

http://<your-server-ip>

Or if DNS is configured:

http://your-domain.com

Replace <your-server-ip> and your-domain.com with your actual server IP address or domain name.
