Purchasing a FlexusL Instance
Scenarios
This section describes how to purchase a FlexusL instance on the FlexusL instance management console. You can configure the region, image, instance specifications, required duration, and other parameters for your FlexusL instances based on your service requirements.
Constraints
If you need to use a private image to create a FlexusL instance, understand the constraints on private images of the FlexusL instance in case the image cannot be used after the instance is created.
Preparations
- Before purchasing a FlexusL instance, sign up for a HUAWEI ID and enable Huawei Cloud services. For details, see Signing Up a HUAWEI ID and Enabling Huawei Cloud Services and Completing Real-Name Authentication.
If you have enabled Huawei Cloud services and completed real-name authentication, skip this step.
- Ensure that your account has sufficient balance. If not, top up your account.
- If you want to use a private image to create a FlexusL instance, create a private image on the Image Management Service (IMS) console. Private images can be used by FlexusL instances only after they are created on the IMS console. For more information, see Creating a FlexusL Instance from a Private Image or Using a Private Image to Change the OS.
Procedure
Follow the steps below to purchase a FlexusL instance.
- Log in to the FlexusL console and click Buy FlexusL.
- Specify parameters for the FlexusL instance.
Parameter
Description
Region
For low network latency and quick resource access, select the region nearest to your target users. After a FlexusL instance is created, the region cannot be changed. Exercise caution when selecting a region.
NOTE:
- By default, all FlexusL instances created by the same account in the same region are located in the same VPC. They can communicate with each other over a private network. FlexusL instances that are created by different accounts or located in different regions cannot communicate with each other over a private network.
- When instances in the regions outside the Chinese mainland access clients in the Chinese mainland across borders, there may be network latency and packet loss.
Image
FlexusL provides OS images, a rich variety of application images, and private images for you to select. Before using a private image, you need to learn about the constraints on private images first and then create a private image. For details, see Images Supported by FlexusL Instances.
Instance Specifications
You can select instance specifications based on your service requirements. Instance specifications include the vCPU/memory, system disk, monthly data package, and peak bandwidth.
NOTE:
- A FlexusL instance is actually a package of different resources. Resources in the package are created, unsubscribed, and renewed together. Resources in the instance specifications cannot be modified, disassociated, or unsubscribed from separately.
- The excess outbound traffic out of the package will be billed by traffic. For details, see Instance Specifications.
(Optional) Instance Name
You can customize your instance name.
If this parameter is left blank, the instance name is in the default format: image name-region-random number. In a batch creation, a hyphen followed by an incremental number is added to the end of each instance name by default.
(Optional) Associated Services
You can associate the following service resources with your FlexusL instance as needed: data disks (EVS), host security (HSS basic edition), and cloud backup vaults (CBR).
NOTE:
If you do not purchase a data disk during the purchase process, you can purchase it afterwards on the FlexusL console.
Required Duration
The minimum duration of a purchase is one month and the maximum duration is three years.
Auto-renew can be enabled, which means that the purchased FlexusL instances will be automatically renewed before they expire. If you do not enable auto-renew during the purchase process, you can still enable it later after the instances are created.- Monthly: Your subscription will be automatically renewed each month.
- Yearly: Your subscription will be automatically renewed each year.
For more information about auto-renewal rules, see Auto-Renewal Rules.
Quantity
Set the number of FlexusL instances to be purchased.
NOTE:
A FlexusL instance uses the default network configurations during the creation.
- Public network: By default, a fixed elastic IP address (EIP) is assigned to a FlexusL instance. It cannot be changed.
- Private network: By default, a fixed private IP address 172.31.x.x) and VPC (subnet-default-smb) are allocated to a FlexusL instance. They cannot be changed.
If the network segment of an existing FlexusL instance is 192.168.x.x, you need to unsubscribe from the FlexusL instance and delete the VPC (subnet-default-smb) and its associated subnets and security groups. Then, the network segment of the new FlexusL instance is 172.31.x.x.
- Click Buy Now.
On the displayed page, confirm the order details, read and select the agreement, and click Submit.
- Select a payment method and complete the payment.
- Go back to the FlexusL console and view the purchased FlexusL instance.
After a FlexusL instance is created using an application image, do not perform operations such as restarting or stopping the instance, or resetting the password before the image with the pre-installed application is up and running. Otherwise, the installation may fail and you cannot log in to the image application dashboard. For details, see How Do I Check that an Application Image Has Been Up and Running?
Follow-Up Operations
- When a FlexusL instance is being created, the initial password for logging in to the server is not set by default. Set a password by performing Resetting the Password for a FlexusL Instance first and then log in to a FlexusL instance by performing Logging In to a FlexusL Instance Using VNC.
- If you select an application image when creating a FlexusL instance, you can log in to the visual dashboard of the image application for quick configuration. For details, see Best Practices for FlexusL.
- If you select an OS image when creating a FlexusL instance, you need to set up an environment by yourself. You can see Creating an Nginx Server Using the CentOS Image or Setting Up Websites for reference.
NOTE:
When you set up the environment by referring to Setting Up Websites, ensure that the OS image version used by the FlexusL instance is the same as that in the tutorial to prevent command execution failures caused by version incompatibility.
FAQs
- If you use a Linux private image to create a FlexusL instance and the private image is created from a server on another cloud platform or downloaded from a third party, the image may not have the password reset plug-in installed. As a result, the password reset function is unavailable. To install the plug-in, refer to the following:
- What Should I Do If the Password Cannot Be Reset After I Use a Private Linux Image to Create a FlexusL Instance or Change the OS of an Existing Instance and I Forgot the Initial Password of the Private Image?
- What Should I Do If the Password Cannot Be Reset After I Use a Private Linux Image to Create a FlexusL Instance or Change the OS of an Existing Instance and I Know the Initial Password of the Private Image?
- If you use a private image to create a FlexusL instance, and the Host Security Service (HSS) is not protecting the instance, enable HSS by referring to What Do I Do If HSS Is Not Started After I Use a Private Image to Create an L Instance or Change the OS of an Instance?
