Initial Configuration

Overview

After installing Proxmox VE, several important configuration steps are needed to ensure your environment is properly set up. This guide will cover some essential post-installation tasks.

Repository Configuration

One of the most important initial tasks is configuring your Proxmox VE repositories correctly. This ensures:

• Proper package management
• Access to security updates
• Removal of subscription warnings
• System stability

Post-Installation Script

We'll use the ProxmoxVE post-installation script to handle repository configuration automatically:

bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/misc/post-pve-install.sh)"

What This Script Does

The script will help you:

• Configure appropriate package repositories
• Disable the Enterprise repository if not needed
• Enable the No-Subscription repository
• Remove subscription notifications
• Update the system packages

Important

After running the script:

1. Review the changes it suggests carefully
2. Only apply the changes that make sense for your environment
3. When prompted about updates, it's recommended to apply them

System Updates

After configuring repositories:

1. Ensure all system packages are up to date
2. Apply any pending security updates
3. Reboot if required by kernel updates

apt update && apt upgrade -y

Next Steps

With the basic system configuration complete, proceed to:

1. Network Configuration - Set up network bridges for VM connectivity
2. Firewall VM Setup - Create and configure your OPNsense firewall
