Directions

1. Log in and go to the Redis purchase page, configure the following instance information, confirm that everything is correct, and click Buy Now.
   • Billing Mode: pay-as-you-go
   • Region: select the region that you want your TencentDB for Redis instance to be deployed in. We recommend that you use the same region as the CVM instance to be connected to. Tencent Cloud products in different regions cannot communicate with each other over the private network. The region cannot be modified after purchase.
   • Instance Edition: Memory Edition is supported. It is a high-performance edition based on the open-source Redis engine, which is compatible with Redis v2.8, v4.0, and v5.0.
   • Compatible Version: TencentDB for Redis is compatible with Redis v2.8, v4.0, and v5.0. v2.8 is unavailable currently, and v4.0 or later is recommended. To purchase v2.8, please submit a ticket.
   • Architecture: standard architecture or cluster architecture
   • Replica Count: TencentDB for Redis v2.8 (standard architecture) supports 0 or 1 replica; v4.0 or v5.0 (standard or cluster architecture) supports 1 to 5 replicas.
   • Network: select the network where the TencentDB for Redis instance resides. We recommend that you select the same VPC in the same region as the CVM instance to be connected to. After an instance is purchased, you can switch the instance from classic network to VPC, but you cannot switch it from VPC to classic network.
   • Availability Zone: select availability zones for the master node and replica nodes. Multi-AZ deployed instances have higher availability and better disaster recovery capability than single-AZ deployed instances. For more information, please see Multi-AZ Deployment.
   • Port: the custom port number ranging from 1024 to 65535.
   • Project and Security Group: specify the project and security group for the instance.
   • Instance Name and Set Password: you can set the instance name and password here or set them in the instance list after creation.
2. After the purchase is completed, you will be redirected to the instance list. After the status of the instance becomes Running, it can be used normally.
3. (Optional) Click the Edit icon in the Instance ID/Name column in the instance list to rename the instance.
   

Subsequent Operations

• Use a CVM instance to directly access the private IP of the TencentDB instance. For more information, please see Connecting to TencentDB for Redis Instances.
• Use a CVM instance with a public IP to connect to the TencentDB instance over the public network through port forwarding. For more information, please see iptables Forwarding.
