Creating a GeminiDB Influx Instance

This section describes how to create a GeminiDB Influx instance on the GeminiDB console.

Procedure

1. Log in to the GeminiDB console.
2. On the Instances page, click Create DB Instance.
3. On the displayed page, select your DB instance specifications, and click Create Now.

   Table 1 Basic information

   Parameter	Description
   Region	The region where the tenant is located. It can be changed in the upper left corner. NOTICE: Select the region nearest where you will be accessing the DB from so latency can be kept to a minimum and response time will be faster. Also, products deployed in different regions cannot communicate with each other through a private network and you cannot change the region of an instance after creating the instance.
   DB Instance Name	The new name can be the same as an existing instance name. It must start with a letter and consist of 4 to 64 characters. Only letters, digits, hyphens (-), and underscores (_) are allowed.
   Compatible API	InfluxDB
   Storage Type	Cloud native: more flexible, new-gen version with support for more AZs NOTE: Cloud native storage is only available to cluster (performance-enhanced) instances.
   DB Instance Type	Performance-enhanced cluster instances can be created. Cluster: One cluster consists of at least three nodes. A cluster is easy to scale out to meet increasing data growth needs. Compared with cluster instances, instances in a performance-enhanced cluster support a larger scale and higher read/write performance.
   DB Engine Version	1.7
   AZ	An AZ is a part of a region with its own independent power supplies and networks. AZs are physically isolated but can communicate through an internal network connection.

   Table 2 Specifications and storage

   Parameter	Description
   Instance Specifications	Performance specifications vary depending on the connections and maximum IOPS.
   Nodes	The number of nodes ranges from 2 to 9. After an instance is created, you can add nodes. For details, see Adding Nodes.
   Storage Space	The storage is an integer, and the minimum storage is 100 GB. You can add at least 10 GB each time.

   Table 3 Network

   Parameter	Description
   VPC	The virtual network where your DB instances are located. A VPC isolates networks for different services. You can select an existing VPC or create a VPC. If there are no VPCs available, the system allocates resources to you by default. For details on how to create a subnet, see the "Creating a VPC" section in the Virtual Private Cloud User Guide. NOTE: After the GeminiDB Influx instance is created, the VPC where the instance resides cannot be changed.
   Subnet	A subnet provides dedicated network resources that are logically isolated from other networks for network security.
   Security Group	A security group controls access between GeminiDB Influx instances and other services. When you select a security group, you must ensure that it allows the client to access DB instances. If no security group is available, the system creates one for you.
   SSL	Secure Sockets Layer (SSL) encrypts connections between clients and servers, preventing data from being tampered with or stolen during transmission.

   Table 4 Database configuration

   Parameter	Description
   Administrator	The default administrator account is rwuser.
   Administrator Password	Set a password for the administrator. The password: Must be 8 to 32 characters long. Must contain uppercase letters, lowercase letters, digits, and any of the following special characters: ~!@#%^*-_=+? For security reasons, you must select a strong password. The system will verify the password strength. Keep this password secure. If you lose it, the system cannot retrieve it.
   Confirm Password	Enter the administrator password again.
   Parameter Template	A parameter template contains engine configuration values that can be applied to one or more instances. After a DB instance is created, you can modify parameters to better meet your service requirements. For details, see Modifying a Parameter Template.
   Enterprise Project	This parameter is provided for enterprise users. An enterprise project groups cloud resources, so you can manage resources and members by project. The default project is default.

   Table 5 Tags

   Parameter

   Description

   Tags

   The setting is optional. Adding tags helps you better identify and manage your DB instances. You can add a maximum of 20 tags for each instance. A tag is composed of a key-value pair. A tag key is mandatory if the instance will be tagged. Each tag key is unique for each instance. The key can contain 1 to 36 characters, including digits, letters, underscores (_), and hyphens (-). A tag value is optional if the instance will be tagged. The value can contain up to 43 characters, including digits, letters, underscores (_), periods (.), and hyphens (-).

4. On the displayed page, confirm the DB instance details.
   • If you need to modify the specifications, click Previous to return to the previous page.
   • If you do not need to modify the specifications, click Submit to start creating the instance.

5. On the Instances page, view and manage your DB instances.
   • Creating a DB instance takes about 5 to 9 minutes. During the process, the instance status displayed in the DB instance list is Creating.
   • After the creation is complete, the status changes to Available.

     You can click in the upper right corner of the page to refresh the DB instance statuses.

   • During creation, an automated backup policy is enabled by default. A full backup is automatically triggered after a DB instance is created.
   • After a DB instance is created, the default database port is 8635 and cannot be changed.
