Setup NOW Learning Management System in EL9

Update: 2025-05-24 Host: Rocky Linux 9.3

Update your server

Keep your server up to date:

dnf update -y

Enable the web console

With Cockpit you can administer the server with out a SSH daemon.

sudo dnf install cockpit firewalld -y
sudo systemctl enable --now cockpit.socket
sudo systemctl enable firewalld --now
sudo firewall-cmd --add-service=cockpit
sudo firewall-cmd --add-service=cockpit --permanent

Create a sudo user

Do not use the root user:

adduser serveradmin # User a custom user to make it more secure and hard to guest
passwd serveradmin
usermod -aG wheel serveradmin

Now you can admin your server from the web console and there is no need of the SSH daemon, be sure you can loggin with the sudo user at: your_ip:9090

Secure the server

Block access to the root user:

sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config_backup
# No root access
sudo vi /etc/ssh/sshd_config # Set: PermitRootLogin no
systemctl restart sshd

Or disable the SSHD service and use the web console to admin the server [recomended]

systemctl disable --now sshd

Only disable the SSHD server after you have logedin in the web console and verified you can perform administrative tasks.

Install the Caddy Server:

Nginx is another good option:

sudo dnf install -y epel-release
sudo dnf install -y caddy
sudo firewall-cmd --permanent --zone=public --add-service=http
sudo firewall-cmd --permanent --zone=public --add-service=https

Configure the Caddy Server:

mkdir /etc/caddy/
touch /etc/caddy/Caddyfile
vi /etc/caddy/Caddyfile

Set the Caddy Server to act as a reverse proxy: 

:443 {
    reverse_proxy localhost:8080
}

Start the Caddy Server

systemctl enable --now caddy
