This document describes how to purchase and configure a TencentDB for Redis instance.
To register a Tencent Cloud account:
To verify your identity:
|Billing Mode||Pay-as-you-go is supported. For more information, see Billing Overview.|
|Region||Select a region where your instance resides. You should select a region closest to you to reduce access latency.|
|Instance Edition||Select the Memory Edition. The CKV Edition is unavailable currently.|
|Compatible Version||Select a high-performance version based on the open-source Redis engine, which is compatible with Redis 6.0, 5.0, 4.0, and 2.8. v2.8 is unavailable currently, and v4.0 or later is recommended. To purchase an instance of Redis 2.8 or 6.0, submit a ticket for application.|
|Architecture||v4.0 or later supports the standard architecture and cluster architecture, while v2.8 only supports the standard architecture. For more information on the product architecture, see Memory Edition (Standard Architecture) and Memory Edition (Cluster Architecture).|
|Memory||Configure the required memory size (0.25–64 GB) if you select Standard Architecture for Architecture.|
|Replica Quantity||Select the number of database replicas. Multiple replicas can provide master/replica high availability, thus improving the data security. Replicas can also be used to enhance the read-only performance. The replica quantity may vary by region or edition as configured in the console by default.|
|Shard Quantity||Set the number of shards as needed if you select Cluster Architecture for Architecture. The more the shards, the larger the cluster storage capacity.|
|Shard Capacity||Set the capacity of each shard if you select Cluster Architecture for Architecture.|
|Specs Preview||Preview the selected specification and the supported maximum number of connections and maximum network throughput to verify whether they meet your expectations.|
|Read-Only Replica||Specify whether to enable read/write separation. For more information, see Read/Write Separation.|
|Network||Both VPC and classic network are supported. |
|AZ||Specify whether to enable multi-AZ deployment. Both single-AZ deployment and multi-AZ deployment are supported. A multi-AZ deployed instance has higher availability and disaster recovery capabilities than a single-AZ deployed instance. For more information, see Multi-AZ Deployment. |
|IPv4 Network||Network: Select VPC. You should select a specific VPC and subnet, preferably the same VPC in the same region as the CVM instance. VPCs are region-specific (e.g., Guangzhou), while subnets are AZ-specific (e.g., Guangzhou Zone 1). One VPC can be divided into one or multiple subnets, which are interconnected over the private network by default. Different VPCs are isolated over the private network by default, no matter whether they are in the same or different regions. You can switch the VPC after instance purchase as instructed in Configuring Network. You can also click Create VPCs and Create Subnets to create a required network environment as instructed in Creating VPCs.|
|Port||Custom port. The default port is 6379. Value range: 1024–65535.|
|Parameter Template||Apply a parameter template to configure parameters in batches for the instance. For more information, see Applying Parameter Templates.|
|Project||Assign your instance to a project for easy management.|
|Tag||Add tags to your instance for easy classification and management. Click Add to select tag keys and values.|
|Security Group||Set security group rules to control the inbound traffic to your database. You can either select a security group from the Existing Security Groups drop-down list or click Custom Security Groups to create one and set inbound rules. For more information, see Configuring Security Group.|
|Instance Name||Enter up to 60 letters, digits, hyphens, and underscores.|
|Set Password||Password Authentication is selected by default.|
|Password||Set an access password for the instance, which must meet the following requirements:|
|Confirm Password||Enter the access password for the instance again.|
|Quantity||You can purchase up to 100 instances in each region and up to 30 instances each time.|
Use a CVM instance to directly access the private IP of the TencentDB instance. For more information, see Connecting to TencentDB for Redis Instance (over Private Network).
You can elastically adjust the specification of your TencentDB for Redis instance based on your actual business needs to optimize resource utilization and costs in real time. For detailed directions, see Changing Instance Specification.
Assigned instances can be reassigned to other projects. For detailed directions, see Assigning Instances to Projects.
You can edit the tag key and value assigned to an instance. For detailed directions, see Editing Instance Tag.
If the current instance name is difficult to identify and makes instance management inconvenient, you can click in the Instance ID/Name column in the Instance List to rename the instance.
If you forgot or want to change the default account password, you can directly reset it. For detailed directions, see Resetting Password.
After activating TencentDB for Redis, make sure that your account balance is sufficient. An insufficient balance may cause overdue payments or even instance repossession. For more information, see Payment Overdue.
