Create a VPS on Proxmox server using almalinux 9? OS image boot or minimal?

[Helposoft Staff]

Creating a VPS on your Proxmox server using AlmaLinux 9 involves several steps. Here is a detailed guide on how to do it, including information on which OS image to use.

Step 1: Download AlmaLinux 9 ISO​

1. Download the AlmaLinux 9 ISO:
   • Visit the AlmaLinux official website and download the AlmaLinux 9 ISO image.
   • For a VPS setup, the minimal ISO is usually sufficient, but if you need more tools or a graphical interface, you might opt for the boot ISO. The minimal ISO is recommended for a server environment as it is lightweight and includes only the necessary packages.

Step 2: Upload ISO to Proxmox​

1. Log into Proxmox Web Interface:
   • Open your browser and navigate to https://your_server_ip:8006 and log in.
2. Upload ISO Image:
   • Navigate to Datacenter > your node > local (storage) > ISO Images.
   • Click Upload, select the AlmaLinux 9 ISO you downloaded, and upload it to Proxmox.

Step 3: Create a New Virtual Machine​

1. Create a VM:
   • In the Proxmox web interface, click on Create VM.
   • Follow the VM creation wizard:
     • General: Assign a VM ID and name (e.g., almalinux9-vm).
     • OS: Select the AlmaLinux 9 ISO from the list.
     • System: Default settings are typically fine, but ensure you choose UEFI if required.
     • Hard Disk: Allocate storage for your VM (e.g., 20GB or more, depending on your needs).
     • CPU: Allocate CPU cores and set the socket count (e.g., 2 cores).
     • Memory: Allocate RAM (e.g., 2048MB or more).
     • Network: Use the default vmbr0 bridge and set up network settings.
2. Confirm and Finish:
   • Review the settings and click Finish to create the VM.

Step 4: Install AlmaLinux 9 on the VM​

1. Start the VM:
   • Go to Datacenter > your node > your VM.
   • Click Start.
2. Access the Console:
   • Once the VM is running, click on the Console tab to access the VM console.
3. Install AlmaLinux:
   • Follow the installation steps in the console. This will include:
     • Selecting the language.
     • Configuring the disk partitions (use the automatic partitioning for simplicity).
     • Setting up the root password and creating a user.
     • Configuring the network if needed (you may need to set up the static IP here).
4. Complete Installation:
   • Finish the installation process and reboot the VM.

Step 5: Configure Networking​

1. Set Up Networking in AlmaLinux:
   • Log into the VM via the console or SSH (if network configured) and set up the network interfaces.
   • Configure the network settings to match your Proxmox bridge settings, ensuring the VM can access the internet and be reachable.
2. Edit Network Configuration Files:
   • Typically, you will need to edit the network configuration file:
     

     sudo nano /etc/sysconfig/network-scripts/ifcfg-eth0

   • Ensure it looks something like this:
     

     TYPE=Ethernet
     BOOTPROTO=static
     NAME=eth0
     DEVICE=eth0
     ONBOOT=yes
     IPADDR=your_vm_ip
     NETMASK=255.255.255.0
     GATEWAY=your_gateway_ip
     DNS1=8.8.8.8

     Restart Network Service:

3. sudo systemctl restart network

Step 6: Verify Access​

1. Access the VPS:
   • You should now be able to access the VPS via SSH using the IP address you configured.

Additional Tips​

• Snapshots: Consider taking snapshots of your VM at various stages to easily roll back if something goes wrong.
• Firewall: Ensure your firewall settings on Proxmox and within AlmaLinux are correctly configured to allow the necessary traffic.
• Updates: Regularly update both Proxmox and AlmaLinux for security and stability.

By following these steps, you should have a fully functional AlmaLinux 9 VPS running on your Proxmox server.
