This topic describes how to create a standalone instance in the ApsaraDB for MongoDB console.

Prerequisites

  • An Alibaba Cloud account is registered. For more information, see Sign up with Alibaba Cloud.
  • Your account balance is sufficient if you want to create a pay-as-you-go instance.

Billing

For more information, see Billing items and pricing.

Procedure

  1. Log on to the ApsaraDB for MongoDB console.
  2. In the upper-left corner of the page, select the resource group and the region of the target instance.
  3. In the left-side navigation pane, click Replica Set Instances.
  4. On the Replica Set Instances page that appears, click Create Instance.
  5. Click the Pay-As-You-Go(Replica Set) tab.
  6. Configure the instance. The following table describes related parameters.
    Section Parameter Description
    Basic Configuration Region

    The region where the ApsaraDB for MongoDB instance is deployed. Standalone instances can only created in the following regions: China (Hangzhou), China (Shanghai), China (Qingdao), China (Beijing), and China (Shenzhen).

    Note
    • After an instance is created, you cannot change its region. Use caution when you select the region.
    • Only instances in the same region (for example, an ECS instance and a standalone ApsaraDB for MongoDB instance) can communicate with each other inside an internal network.
    Zone

    Geographic areas in a region with independent power grids and networks. For more information, see Regions and zones.

    Note An ECS instance and a standalone ApsaraDB for MongoDB instance in the same zone can be interconnected over an internal network with the minimum network latency.
    Database Version

    Standalone instances support MongoDB 3.4. Select MongoDB 3.4.

    Storage Engine

    The storage engine is WiredTiger.

    Replication Factor Select Single Node.
    Network Type VPC A VPC is an isolated network with higher security and performance than a classic network.
    Note You must create a VPC in advance. For more information, see Create a VPC network.
    Specifications Specification
    • The CPU and memory occupied by the instance.
    • The maximum number of connections and maximum IOPS vary depending on different specifications. The maximum IOPS is measured for read and write operations separately, and the maximum sum of read and write operations can be twice the maximum IOPS. For more information, see Instance types.
    Storage Space The storage space of the instance.
    Note The storage space stores your data, system files, and log files.
    Set Password
    • Set Now
    • Set Later

    The password of the root user. You can set a password immediately or reset it during the running of the instance. For more information, see Set a password.

    • The password must contain at least three of the following character types: uppercase letters, lowercase letters, digits, and special characters. Special characters include #$%^&*()_+-=
    • The password must be 8 to 32 characters in length.
    Quantity Duration
    Pay-as-you-go: Select the quantity for pay-as-you-go instances to be purchased with the same configuration. You can select an integer in the range of 1 to 10.
    Note The billing method of standalone instances must be pay-as-you-go.
    Quantity
  7. Click Buy Now to go to the Confirm Order page.
  8. On the Confirm Order page that appears, read and select ApsaraDB for MongoDB Agreement of Service and follow the instructions to complete the payment process.

View the created instance

  1. Log on to the ApsaraDB for MongoDB console.
  2. In the upper-left corner of the page, select the resource group and the region of the target instance.
  3. In the left-side navigation pane, click Replica Set Instances.

Troubleshoot if you cannot find the instance

Possible causes Solution
You selected the wrong region in the console. Select the region where the instance is deployed. For more information, see View the created instance.
You opened the incorrect page. In the left-side navigation pane, click Replica Set Instances. For more information, see View the created instance.
The instance list in the ApsaraDB for MongoDB console is not updated or updated before the instance is created. Wait for several minutes and then update the instance list to check whether the instance is added to the list.
Resources are insufficient.

The system may fail to create the instance due to insufficient resources. In this case, your payment is refunded. You can check the refund on the Orders page.

After you confirm the refunded fees, you can try to create the instance in another zone. You can also submit a ticket.

What to do next

After you create an instance, you must configure a whitelist (for more information, see Configure a whitelist for a standalone ApsaraDB for MongoDB instance). If you want to connect to the instance over the Internet, you must apply for a public endpoint (for more information, see Apply for a public endpoint for a standalone ApsaraDB for MongoDB instance).
