Vultr设置浮动ip保留IP教程

2022-10-08 WEB 1.06k

在Vultr的后台Network中有个Reserved IPs功能用来保留ip，也就是DO中的浮动IP功能。

该功能会分配一个ip来保留你vps的IP地址，当IP ping不通的时候避免频繁申请新容器来更换IP。

只需重新分配保留IP来解析即可。

Vultr的保留IP功能是收费的，一个IP每月3美金。

使用方面没有DO方便，申请并挂靠容器成功后，需要在vps中修改配置才能生效，之后解析到域名即可。

申请并挂靠：

之后在容器设置中参考教程设置：

以下是官方关于设置的教程。

Important Information

  • In most cases, you should not need to adjust these files. Instances are normally configured using DHCP. You only really need to change these files if you are trying to enable additional IPs.
  • Changing to the examples below will cause problems if you take a snapshot of an instance and restore it. We recommend reverting back to DHCP before taking a snapshot.
  • You must restart your server via the control panel after adding extra IPs.

netplan apply

Windows Server 2012 R2, Windows Server 2016, Windows Server 2019

To configure the main IPv4 manually:

  1. Open the windows control panel. You can access it from the start menu.
  2. Click "Network and Internet".
  3. Click "Network and Sharing Center".
  4. Click "Change adapter settings".
  5. Right click on the primary ethernet adapter, and click "Properties". The "Ethernet Properties" window will open.
  6. Select "Internet Protocol Version 4 (TCP/IPv4)", then click the "Properties" button. The "Internet Protocol Version 4 (TCP/IPv4) Properties" window will open.
  7. Check the box that reads "Use the following IP address:". Populate the fields:
    • IP address: 139.180.207.244
    • Subnet mask: 255.255.254.0
    • Default gateway: 139.180.206.1
  8. Check the box that reads "Use the following DNS server addresses:". Populate the fields
    • Preferred DNS server: 108.61.10.10
    • Alternate DNS server: (blank)
  9. Click "OK". Then click "OK" on the "Ethernet Properties" window. The main IPv4 has been configured manually. Note that it is normal for the connection to hiccup after pressing "OK".

The main IPv4 address must be configured manually before adding more IPv4 addresses. To add your additional IPv4 addresses:

  1. Follow the steps above and navigate to the "Internet Protocol Version 4 (TCP/IPv4) Properties" window for the primary ethernet adapter.
  2. Click "Advanced...". The "Advanced TCP/IP Settings" window will open.
  3. In the "IP addresses" group, click "Add...". The "TCP/IP Address" window will open. Add addresses:
    • IP address: 108.61.161.107, Subnet mask: 255.255.255.255
  4. Click "OK" on the "Advanced TCP/IP Settings" window. This window will close.
  5. Click "OK" on the "Internet Protocol Version 4 (TCP/IPv4) Properties" window. This window will close.
  6. Click "OK" on the "Ethernet Properties" window. This window will close, and your additional IP addresses will be configured. Note that it is normal for the connection to hiccup after pressing "OK".
