A CVM instance can be used to access the private address that is automatically assigned to a TencentDB instance. This connection method relies on the high-speed private network of Tencent Cloud and features low delay. Both instances should be under the same account and reside in the same VPC in the same region or reside in the basic network.

Note：

CVM and TencentDB instances in different VPCs (under the same or different accounts in the same or different regions) can be interconnected over the private network through Peering Connection.

Environment Preparations

1. Log in to a Linux CVM instance. For more information, please see Configuring Linux CVM.
2. Taking a CVM instance on CentOS as an example, Install the Redis client by running the following command:

   yum install redis -y

   If Complete! is displayed, it means the Redis client is installed successfully.

Instance Connection

Password-free instance

If your instance is password-free, the connection command should be as follows:

redis-cli -h IP address -p port

Password-protected instance

If your instance is password-protected, the following open-source connection format is supported:

redis-cli -h IP address -p port -a password

For example, if the password you set is abcd1234, then the connection command should be as follows:

redis-cli -h IP address -p port -a abcd1234

Note：

For instances purchased before January 2018, you need to replace the "password" with "instance ID:password" to access it. For example:
redis-cli -h IP address -p port -a crs-bkuza6i3:abcd1234

Connection Sample

For examples of each connection format, please see Connecting to Instances.
