Steps to install Caddy on Almalinux or Rocky Linux 8 server
The given steps and commands will also work for other RHEL or RPM based Linux operating systems such as CentOS / RedHat 8 / Oracle Linux…
What do you need to complete this guide?
A user with
Almalinux or Rocky
Of course, Internet connection.
1. Run the DNF update
If you are using a new server or if you have not updated your server for a while, run the system update command first. This will rebuild the DNF repository cache.
sudo dnf update
2. Install the Copr repository on Almalinux or Rocky 8
Unlike Apache or Nginx, the packages we needed to install the Web Caddy server are not available through the default base repository of Almalinux 8 or Rocky Linux. Therefore, we need to add a Fedora managed repository called Copr. It hosts over 17,000 projects and is intended to automatically deliver installation packages for those projects to Fedora and other Linux RPM users whenever users call them up. However, before that, we need to add it manually to our system using the given command.
sudo dnf install 'dnf-command(copr)'
3. Activate the Caddy server repository
Now, activate which package repository you want to activate, this is Caddy.
sudo dnf copr enable @caddy/caddy
Run the system update again
sudo dnf update
4. Command to install Caddy on Rocky or AlmaLinux 8
Finally, we can use the DNF package manager to install the Caddy web server just like HTTPd or any other application from the command terminal.
sudo dnf install caddy
5. Start and activate the Caddy service
After installation is complete, the caddy server service might not work by default on your system. Therefore, start it and activate it manually. And to confirm use the status command:
sudo systemctl start caddy
To allow, so that it can start automatically:
sudo systemctl enable caddy
systemctl status caddy
6. Open ports 80 and 443 in the firewall
If you are using the built-in firewall from Almalinux, Rocky, or any other RHEL based system, use the given command to open ports 80/443. However, those that are in the cloud such as Google, AWS, etc. must allow public access to these ports or HTTP / HTTPS in their service provider’s firewall.
For port 80 or HTTP
sudo firewall-cmd --permanent --add-service=http
For port 443 or HTTPS:
sudo firewall-cmd --permanent --add-service=https
Reload the system firewall:
sudo systemctl reload firewalld
7. Access the web server demo page
To confirm that the server is operational to serve our web pages without generating an error, let’s access it using the web browser. On your system, open the browser and enter this
ip-address or the domain name of the server on which you are running Caddy.
server-ip should be replaced with the actual address of your server which can be found using the command
ip a Likewise, if you have transferred a domain to your server, you can also access the Caddy using it.
To modify the Caddy host configuration file:
sudo nano /etc/caddy/Caddyfile
You can change the root path to any web page server you want.
