Purchasing a FlexusL Instance

Procedure

1. Log in to the FlexusL console and click Buy FlexusL.
2. 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. For details, see Resource Configuration for FlexusL Instances.
   Image	FlexusL provides OS images, application images, and private images for you to choose from. You need to learn about the constraints and usage of private images by referring to Managing Private Images before using them. NOTICE: The purchased FlexusL instance and the selected private image must be in the same region. For example, if you intend to purchase an instance in the AP-Singapore region, you can only select private images in the AP-Singapore region. To use an image in another region, replicate that image to the current region first by referring to Replicating Images Across Regions. If the message "This image has no password reset plug-in installed or onekey_resetpasswd tagged." is displayed when you use a private image to create a FlexusL instance or change the OS, resolve this issue by referring to What Should I Do If a Private Image Cannot Be Used to Create a FlexusL Instance or Change the OS of an Instance Because the Password Reset Plug-in Is Not Installed on the Image or the Image's onekey_resetpasswd Tag Is Missing?
   Instance specifications	You can select instance specifications based on your service requirements. Outbound traffic exceeding the traffic package is billed. For billing details, see Billing. NOTE: If you use a private image, ensure that the image specifications are appropriate for creating this instance, or the instance creation or start may fail.
   (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 service resources	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 select Data Disk (EVS) during the purchase process, you can purchase it afterwards at the same price.
   Required duration	The minimum duration of a purchase is one month and the maximum duration is three years. Auto-renew is enabled by default, which means 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 subscription: auto-renews for 1 month every time Yearly subscription: auto-renews for 1 year every time For details about auto-renewal, see Auto-Renewal Rules.
   Quantity	Set the number of FlexusL instances to be purchased.

4. Select a payment method and complete the payment.
5. Go back to the FlexusL console and view the purchased FlexusL instance.

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 first and then log in to the FlexusL instance.
• 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.
  

  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.
