2.Creating a Windows System Disk Image from an ECS
Show less
If you have created and configured a Windows ECS based on your service requirements (for
example, by installing software and setting up an application environment), you can create a
system disk image based on this configured ECS. Then, all new ECSs created from this image
will have the same software and environment preinstalled.
To create a Windows system disk image using an ECS, you need to configure a Windows ECS
and then use it to create a system disk image.
2.1 Configuring a Windows ECS
Take the ecs-windows ECS you created as an example.
Step 1 Remotely log in to the ECS.
Step 2 Check whether DHCP is configured for the ECS NICs. If it is not, configure it.
1. Choose Start > Control Panel. (The GUI varies somewhat depending on the OS version.)
2. Click Network and Sharing Center.
3. Click a network connection, for example, Ethernet 2.
4. Click Properties, select Internet Protocol Version 4 (TCP/IPv4), and click Properties.
5. If Obtain an IP address automatically and Obtain DNS server address automatically are sel
ected, DHCP has been configured. Otherwise, select the two check boxes and click OK.
Step 3 Click Start, right-click This PC, and choose Properties.In the navigation pane to the left of
the System page, click Remote settings. Select Allow remote connections to this computer. Cli
ck OK. (The GUI varies somewhat depending on the OS version.)
Step 4 Go to Start > Control Panel and navigate to Windows Firewall.In the left pane, select All
ow an app or feature through Windows Firewall. Select apps that are allowed by Windows Fire
wall for Remote Desktop based on your network requirements and click OK.
In this exercise, both the private and public networks are allowed by the firewall.
Step 5 Check whether Cloudbase-Init is installed on the ECS. If it is not, install it.
Go to Start > Control Panel > Programs and Features to check whether Cloudbase-Init has b
een installed on the ECS.
Note:
If Cloudbase-Init is not installed on the ECS, custom information cannot be injected into the ne
w ECSs created from the private image. You will only be able to log in to the ECSs with the passw
ord specified in the image.
For an ECS created from a public image, Cloudbase-Init has been installed on it by default. You
do not need to manually install Cloudbase-Init for it.
For an ECS created using an external image file, you need to install Cloudbase-Init for the ECS
before you use it to create a private image. For details, see Installing and Configuring Cloudbase-I
nit (https://support.huaweicloud.com/intl/en-us/usermanual-ims/en-us_topic_0030730602.html).
In this exercise, the ECS is created from the public image windows2012 R2, which has Cloudb
ase-Init installed by default.
2.2 Creating a Windows Private Image
Step 1 Go back to the management console and in Service List choose Compute > Image Mana
gement Service.
Step 2 On the Image Management Service page, click Create Image.
Step 3 On the Create Image page, set the following parameters and click Next.(Retain the defaul
ts for the rest of the parameters.)
Region: AP-Singapore
Type: System disk image
Source: Select a Windows ECS, for example, ecs-windows.
Name: Enter a name, for example, image-windows2012.
Step 4 Confirm the settings. Then, select I have read and agree to the Image Disclaimer and clic
k Submit.
Step 5 Switch back to the Private Images tab page to view the image status.
The time required for creating an image depends on the image size. Generally, it takes about
10 to 20 minutes. When the image creation completes, its status changes to Normal.
2.3 Modifying Image Information
Step 1 Locate the row that contains the image to be modified and click Modify in the Operatio
n column.
Step 2 You can modify the image name, memory, and other details.
2.4 Replicating an Image Within a Region
Step 1 On the Image Management Service page, click Private Image to display the image list.
Step 2 Locate the row that contains the image to be replicated and in the Operation column cho
ose More > Replicate.
Step 3 In the displayed Replicate Image dialog box, enter a new name for the image and click O
K. (Do not select KMS encryption.)
2.5 Applying for an ECS Using a Private Image
Step 1 On the Private Images tab page, locate the image and click Apply for Server in the Oper
ation column.
Step 2 On the ECS purchase page, ensure that the private image is selected.
Step 3 Go back to the ECS list to view the ECS created using the private image.
If you have created and configured a Linux ECS based on your service requirements (for exa
mple, by installing software and setting up an application environment), you can create a sys
tem disk image based on this configured ECS. Then, all new ECSs created from this image wil
l have the same software and environment preinstalled.
To create a Linux system disk image using an ECS, you need to configure a Linux ECS and then us
e it to create a system disk image.
3.1 Configuring a Linux ECS
Take the ecs-linux ECS you created as an example.
Step 1 Remotely log in to the ECS.
Step 2 Check whether DHCP is configured for the ECS NICs. If it is not, configure it.
For CentOS, you can configure DHCP by adding PERSISTENT_DHCLIENT="y" to the /etc/sysc
onfig/network-scripts/ifcfg-ethX configuration file using the vi editor.
vi /etc/sysconfig/network-scripts/ifcfg-
eth0
Step 3 Check whether the one-click password reset plug-in has been installed on the ECS. If it is n
ot, install it.
Note: To ensure that you can reset the passwords of the new ECSs created from a private im
age, you are advised to install the one-click password reset plug-in (CloudResetPwdAgent) o
n the ECS used to create the image. For details, see Installing the One-Click Password Reset
Plug-In (https://support.huaweicloud.com/intl/en-us/usermanual-ims/ims_01_0408.html).
In this exercise, the ECS is created from a public image. Therefore, the one-click password reset
plug-in has been installed on it by default. You do not need to manually install it. You can run the
following command to check whether CloudResetPwdAgent has been installed:
ls -lh /Cloud*
If the following information is displayed, the plug-in has been installed:
Step 4 Check whether Cloud-Init is installed. If it is not, install it.
Note:
If Cloud-Init is not installed on the ECS, custom information cannot be injected into the new EC
Ss created from the private image and you can only log in to the ECSs with the password specifie
d in the image.
For an ECS created from a public image, Cloud-Init has been installed on it by default. You do
not need to manually install Cloud-Init for it.
For an ECS created using an external image file, you need to install Cloud-Init for the ECS befor
e you use it to create a private image. For details, see Installing Cloud-Init (https://support.huawei
cloud.com/intl/en-us/usermanual-ims/en-us_topic_0030730603.html) and Configuring Cloud-Init
(https://support.huaweicloud.com/intl/en-us/usermanual-ims/ims_01_0407.html).
In this exercise, the ECS is created from the public image CentOS 7.6 64bit(40GB). Cloud-Init
has been installed on it by default. You can run the following command to check whether Cl
oud-Init has been installed:
rpm -qa |grep cloud-init
If information similar to the following is displayed, Cloud-Init has been installed:
If no command output is displayed, Cloud-Init is not installed. Run the following commands to
install it (before the installation, make sure an EIP is bound to the ECS so that the ECS can access
the Internet):
Yum install
https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum install cloud-init
Step 5 Delete files from the network rule directory.
Note: To prevent NIC name drift on the new ECSs created from a private image, you need to
delete network rule files of the ECS used to create the image.
Run the following command to check if there is a network rule file on the ESC:
ls -l /etc/udev/rules.d
If information similar to the following is displayed, no network rule files exist:
Note:
An ECS created from a public image does not have network rule files by default.
An ECS created using an external image file may have network rule files, delete the files by foll
owing the instructions provided in Deleting Files from the Network Rule Directory (https://suppor
t.huaweicloud.com/intl/en-us/usermanual-imss/ims_01_0406.html).
3.2 Creating a Linux Private Image
