Setting up an old Windows computer as a Linux server and then adding Virtual Private Server (VPS) capabilities involves several steps. Below is a
comprehensive guide to help you through the process.
Step 1: Prepare Your Old Windows Computer
1. Backup Data: Ensure that any important data on the Windows computer is backed up, as the installation of Linux will likely overwrite the existing
data.
2. Check Hardware Requirements: Verify that the computer meets the minimum hardware requirements for the Linux distribution you plan to use.
Common lightweight distributions include:
- Ubuntu Server
- Debian
- CentOS
- AlmaLinux
- Arch Linux
3. Create a Bootable USB Drive:
- Download the ISO file for your chosen Linux distribution.
- Use a tool like Rufus (for Windows) to create a bootable USB drive with the downloaded ISO.
Step 2: Install Linux
1. Boot from USB:
- Insert the bootable USB into the old computer and restart it.
- Access the BIOS/UEFI settings (usually by pressing F2, F10, DEL, or ESC during startup) to set the USB drive as the primary boot device.
2. Install Linux:
- Follow the installation prompts to install Linux on the computer. You can choose to erase the existing Windows installation or set up a dual boot if
you want to keep Windows.
3. Configure Basic Settings:
- Set up your user account, hostname, and network settings during installation.
Step 3: Set Up SSH Access
1. Install SSH Server:
- After installation, open the terminal and install the OpenSSH server to enable remote access:
bash
sudo apt update
sudo apt install openssh-server
1. Start and Enable SSH:
- Ensure the SSH service is running:
bash
sudo systemctl start ssh
sudo systemctl enable ssh
1. Access Your Server Remotely:
- Use an SSH client (like PuTTY or the terminal) to connect to your server using its IP address.
Step 4: Set Up a VPS Environment
To set up VPS capabilities, you can use virtualization software. Here are two popular options:
Option 1: Using KVM (Kernel-based Virtual Machine)
1. Install KVM and Required Packages:
bash
sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils
1. Verify Installation:
- Check if KVM is installed correctly:
bash
sudo kvm-ok
1. Manage Virtual Machines:
- You can use virt-manager for a graphical interface or virsh for command-line management.
- Install virt-manager :
bash

sudo apt install virt-manager
1. Create Virtual Machines:
- Launch virt-manager from the terminal or applications menu to create and manage your virtual machines.
Option 2: Using Docker
1. Install Docker:
bash
sudo apt update
sudo apt install docker.io
sudo systemctl start docker
sudo systemctl enable docker
1. Run Containers:
- Use Docker to create lightweight containers that can act similarly to VPS instances.
- Example command to run a basic Ubuntu container:
bash
docker run -it ubuntu
Step 5: Configure Networking
1. Set Up Network Bridge (for KVM):
- Configure a bridge network to allow VMs to communicate with the outside world. Edit your network configuration file (e.g., /etc/netplan/01-
netcfg.yaml for Ubuntu) to include bridge settings.
2. Firewall Configuration:
- Ensure your firewall settings allow SSH and any other necessary ports for your VMs.
Step 6: Maintain Your Server
1. Regular Updates: Regularly update your Linux server to keep it secure:
bash
sudo apt update
sudo apt upgrade
1. Monitor Performance: Use tools like htop or glances to monitor system performance and resource usage.
2. Backup VMs: Implement a backup strategy for your virtual machines to prevent data loss.
Conclusion
By following these steps, you can successfully set up an old Windows computer as a Linux server and manage VPS instances on it. The choice between KVM
and Docker will depend on your specific needs and the resources available on your hardware.
