How to Assign a static IP to a VPS?

[Helposoft Staff]

To assign a static IP address to a VM in Proxmox VE, you'll need to configure the network settings inside the VM's operating system. Here’s a step-by-step guide on how to do this, assuming you're using AlmaLinux (or a similar Linux distribution):

1. Access the VM Console​

1. Open Proxmox VE Web Interface:
   • Navigate to your Proxmox VE web interface.
2. Select Your VM:
   • Click on the VM you want to configure.
3. Open the Console:
   • Go to the "Console" tab to access the VM’s console.

2. Configure Network Settings Inside the VM​

You need to configure the network settings inside the VM's operating system to assign the static IP address. Here’s how to do it for AlmaLinux and similar Linux distributions:

For AlmaLinux 8 (or CentOS/RHEL 8)​

1. Log into the VM:
   • Log in using your root or a user with sudo privileges.
2. Edit the Network Configuration File:
   • The network configuration files are located in /etc/sysconfig/network-scripts/. Find the appropriate file, usually named ifcfg-eth0 or ifcfg-enp0s3 (the name might differ based on your network interface).

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

or

vi /etc/sysconfig/network-scripts/ifcfg-eth0

1. Modify the Configuration File:
   • Change the file to configure the static IP. Here’s an example configuration for a static IP:
     
     

     TYPE=Ethernet
     BOOTPROTO=static
     NAME=eth0
     DEVICE=eth0
     ONBOOT=yes
     IPADDR=31.172.XX.XXX
     NETMASK=255.255.255.0
     GATEWAY=31.172.XX.X
     DNS1=8.8.8.8
     DNS2=8.8.4.4

   • Replace eth0 with your network interface name if it's different, and set the IPADDR, NETMASK, GATEWAY, DNS1, and DNS2 values according to your network configuration.
2. Restart the Network Service:
   • Apply the changes by restarting the network service:
     
     

     systemctl restart network

   • Alternatively, you can reboot the VM:
     
     

     reboot

For AlmaLinux 9 (or CentOS/RHEL 9)​

1. Log into the VM:
   • Log in using your root or a user with sudo privileges.
2. Use nmcli to Configure Network:
   • For newer systems using NetworkManager, you can configure the static IP using nmcli:
     
     

     nmcli con show

     Identify the connection name, then set the static IP:
     
     

     nmcli con mod "YourConnectionName" ipv4.addresses 31.172.XX.XXX/24
     nmcli con mod "YourConnectionName" ipv4.gateway 31.172.XX.X
     nmcli con mod "YourConnectionName" ipv4.dns "8.8.8.8 8.8.4.4"
     nmcli con mod "YourConnectionName" ipv4.method manual
     nmcli con up "YourConnectionName"

   • Replace "YourConnectionName" with the actual name of your network connection.

3. Verify the Static IP Configuration​

1. Check the IP Address:
   • Use the ip command to verify the IP address:
     
     

     ip a

   • Ensure the interface has the correct static IP assigned.
2. Test Connectivity:
   • Test network connectivity to ensure the VM can reach external networks:
     
     

     ping -c 4 google.com

   • Test connectivity to other devices on your network.

4. Proxmox VE Network Configuration (Optional)​

If you need to ensure that your VM is properly connected to the Proxmox network bridge:

1. Check Network Configuration:
   • Verify that the VM's network adapter is connected to the correct bridge (e.g., vmbr0):
     • Go to the "Hardware" tab of your VM in the Proxmox web interface.
     • Ensure the network device is set to the correct bridge.
2. Apply and Save Changes:
   • Make sure any changes are applied and saved.

Summary​

• Configure the VM's network interface inside the OS to use a static IP address.
• Restart the network service or reboot the VM to apply the changes.
• Verify the IP address and network connectivity.

By following these steps, you can assign a static IP address to your VM and ensure that it is properly configured within Proxmox VE. If you encounter issues or need additional assistance, feel free to ask!
