This configuration opens Coolify’s web interface port (8000), WebSocket port (6001), terminal port (6002), and ensures SSH access remains available.

Coolify Installation Methods

Coolify offers two distinct installation approaches: quick installation using an automated script, and manual installation for users requiring granular control over the process.

Quick Installation (Recommended)

The automated installation script provides the most straightforward path to getting Coolify operational on Fedora 42. This method handles dependency verification, service configuration, and initial setup automatically.

Execute Installation Script:

curl -fsSL https://cdn.coollabs.io/coolify/install.sh | bash

For non-root users, prefix the command with sudo:

curl -fsSL https://cdn.coollabs.io/coolify/install.sh | sudo bash

The installation script performs several critical operations:

Verifies system compatibility and requirements
Installs missing dependencies automatically
Configures Docker if not properly set up
Creates necessary directory structures
Generates SSH keys for server management
Initializes Coolify services and containers

During installation, you’ll see progress indicators showing package installations, Docker configuration, and service initialization. The process typically completes within 5-10 minutes, depending on your server’s performance and internet connection speed.

Installation Verification:
Upon successful completion, the script displays your Coolify access URL:

Your instance is ready to use!
You can access Coolify through your Public IP: http://YOUR_SERVER_IP:8000

Manual Installation Process

Advanced users may prefer manual installation for greater control over each configuration step. This approach requires more technical expertise but offers customization opportunities not available through automated installation.

Create Directory Structure:

sudo mkdir -p /data/coolify/{source,ssh,applications,databases,backups,services,proxy,webhooks-during-maintenance}
sudo mkdir -p /data/coolify/ssh/{keys,mux}
sudo mkdir -p /data/coolify/proxy/dynamic

Generate SSH Keys:

sudo ssh-keygen -f /data/coolify/ssh/keys/id.root@host.docker.internal -t ed25519 -N '' -C root@coolify
sudo cat /data/coolify/ssh/keys/id.root@host.docker.internal.pub >> ~/.ssh/authorized_keys
sudo chmod 600 ~/.ssh/authorized_keys

Set Proper Permissions:

sudo chown -R 9999:root /data/coolify
sudo chmod -R 700 /data/coolify

Manual installation requires downloading and configuring Docker Compose files, environment variables, and service definitions. While more complex, this approach allows for custom network configurations and advanced security settings.

Post-Installation Configuration

Once Coolify installation completes, several configuration steps ensure optimal functionality and security. Initial setup involves creating administrator accounts, configuring server connections, and establishing basic security measures.
