Change IP

You can change the Virtual Server’s IP and add a network port to the Virtual Server to configure the IP.

Change IP

You can change the IP of the Virtual Server.

Caution
  • If you proceed with changing the IP, you will no longer be able to communicate using that IP, and you cannot cancel the IP change while it is in progress.
  • The server is rebooted to apply the changed IP.
  • If the server is running the Load Balancer service, you must delete the old IP from the LB server group and directly add the new IP as a member of the LB server group.
  • Servers using Public NAT/Private NAT must disable and reconfigure Public NAT/Private NAT after changing the IP.
    • If you are using Public NAT/Private NAT, first disable the use of Public NAT/Private NAT, complete the IP change, and then reconfigure.
    • You can change the usage of Public NAT/Private NAT by clicking the Edit button of Public NAT IP/Private NAT IP on the Virtual Server Details page.
  • Public NAT IP can only be modified when there is one server, the VPC is connected to an Internet Gateway, and the regular subnet is public.

To change the IP, follow these steps.

  1. All Services > Compute > Virtual Server Click the menu. 1. Go to the Service Home page of the Virtual Server.
  2. Click the Virtual Server menu on the Service Home page. 2. Go to the Virtual Server List page.

Configure IP on the server after adding a network port

If you create a Virtual Server with Ubuntu Linux, after adding a network port in Samsung Cloud Platform, you also need to configure the IP on the server.

  1. As the root user on the Virtual Server’s OS, use the ip command to verify the assigned network interface name.

    • If an added interface is present, the following result is displayed.

    [root@scp-test-vm-01 ~] # ip a

  2. Open the /etc/netplan/50-cloud-init.yaml file using a text editor (e.g., vim).

  3. Add the following content to the /etc/netplan/50-cloud-init.yaml file and save it.

    Color mode

Reference
Indentation is important in YAML files that configure netplan. When modifying a YAML file, please refer to the existing settings and be careful.

  1. Use the netplan command to set an IP on the added network DEVICE.

  2. Use the ip command to verify that the IP is set correctly.
