Installing and Configuring Cloudbase-Init

Scenarios

To ensure that you can use the user data injection function to inject initial custom information into ECSs created from a private image (such as setting the ECS login password), install Cloudbase-Init on the ECS used to create the image.

• If Cloudbase-Init is not installed, you cannot configure an ECS. As a result, you can only use the password in the image file to log in to the ECS.
• By default, ECSs created from a public image have Cloudbase-Init installed. You do not need to install or configure Cloudbase-Init on such ECSs.
• For ECSs created from external image files, install and configure Cloudbase-Init by performing the operations in this section.

Prerequisites

• An EIP has been bound to the ECS.
• You have logged in to the ECS.
• The IP address obtaining mode of the ECS is DHCP.

Install Cloudbase-Init

1. On the Windows Start menu, choose Control Panel > Programs > Programs and Features and check whether Cloudbase-Init is installed.
   • If yes, go to Configure Cloudbase-Init.
   • If no, go to the next step.
2. Check whether the version of the OS is Windows desktop.
   • If yes, go to 3.
   • If the OS is Windows Server, go to 4.
3. Enable the administrator account (Windows 7 is used as an example).
   1. Click Start and choose Control Panel > System and Security > Administrative Tools.
   2. Double-click Computer Management.
   3. Choose System Tools > Local Users and Groups > Users.
   4. Right-click Administrator and select Properties.
   5. Deselect Account is disabled.
4. Download the Cloudbase-Init installation package.

   Download the Cloudbase-Init installation package of the appropriate version based on the OS architecture from the Cloudbase-Init official website (http://www.cloudbase.it/cloud-init-for-windows-instances/).

   Cloudbase-Init has two versions: stable and beta.

   To obtain the stable version, visit the following paths:

   • 64-bit: https://www.cloudbase.it/downloads/CloudbaseInitSetup_Stable_x64.msi
   • 32-bit: https://www.cloudbase.it/downloads/CloudbaseInitSetup_Stable_x86.msi

   To obtain the beta version, visit the following paths:

   • 64-bit: https://www.cloudbase.it/downloads/CloudbaseInitSetup_x64.msi
   • 32-bit: https://www.cloudbase.it/downloads/CloudbaseInitSetup_x86.msi
5. Double-click the Cloudbase-Init installation package.
6. Click Next.
7. Select I accept the terms in the License Agreement and click Next.
8. Retain the default path and click Next.
9. In the Configuration options window, enter Administrator for Username, select COM1 for Serial port for logging, and ensure that Run Cloudbase-Init service as LocalSystem is not selected.
   

   The version number shown in the figure is for reference only.

10. Click Next.
11. Click Install.
12. In the Files in Use dialog box, select Close the application and attempt to restart them and click OK.
13. Check whether the version of the OS is Windows desktop.
    • If yes, go to 15.
    • If no, go to 14.
14. In the Completed the Cloudbase-Init Setup Wizard window, ensure that neither option is selected.

15. Click Finish.

Configure Cloudbase-Init

1. Edit the configuration file C:\Program Files\Cloudbase Solutions\Cloudbase-Init\conf\cloudbase-init.conf in the Cloudbase-Init installation path.
   1. Add netbios_host_name_compatibility=false to the last line of the file so that the hostname supports a maximum of 63 characters.
      

      NetBIOS contains no more than 15 characters due to Windows system restrictions.

   2. Add metadata_services=cloudbaseinit.metadata.services.httpservice.HttpService to enable the agent to access the IaaS OpenStack data source.
   3. (Optional) Add the following configuration items to configure the number of retry times and interval for obtaining metadata:

      retry_count=40
      retry_count_interval=5

   4. (Optional) Add the following configuration item to prevent metadata network disconnections caused by the default route added by Windows:

      [openstack]
      add_metadata_private_ip_route=False

   5. (Optional) When the Cloudbase-Init version is 0.9.12 or later, you can customize the length of the password.

      Change the value of user_password_length to customize the password length.

2. Release the current DHCP address so that the created ECSs can obtain correct addresses.

   In the Windows command line, run the following command to release the current DHCP address:

   ipconfig /release

   

   This operation will interrupt network connection and adversely affect ECS use. The network will automatically recover after the ECSs are started again.

3. When creating an image using a Windows ECS, you need to change the SAN policy of the ECS to OnlineAll. Otherwise, EVS disks attached to the ECSs created from the image may be offline.

   Windows has three types of SAN policies: OnlineAll, OfflineShared, and OfflineInternal.

   Table 1 SAN policies

   Type	Description
   OnlineAll	All newly detected disks are automatically brought online.
   OfflineShared	All disks on sharable buses, such as iSCSI and FC, are left offline by default, while disks on non-sharable buses are kept online.
   OfflineInternal	All newly detected disks are left offline.

   1. Execute cmd.exe and run the following command to query the current SAN policy of the ECS using DiskPart:

      diskpart

   2. Run the following command to view the SAN policy of the ECS:
      san

      • If the SAN policy is OnlineAll, run the exit command to exit DiskPart.
      • If the SAN policy is not OnlineAll, go to 3.c.
   3. Run the following command to change the SAN policy of the ECS to OnlineAll:

      san policy=onlineall
