Connecting to Redis Instances (over Private Network)

Last updated: 2021-03-17 15:10:52

    You can connect to a TencentDB for Redis instance using a client tool, the data management console (DMC), and SDKs supporting various programing languages.

    Connecting Using a Client Tool

    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 in the same VPC in the same region, or both in the classic network.


    • CVM and TencentDB instances in different VPCs (under the same or different accounts in the same or different regions) can be interconnected over private network through Peering Connection.
    • To connect to TencentDB for Redis instances over public network, please see iptables Forwarding.

    Step 1. Prepare the environment

    1. Log in to the Linux CVM instance. For more information, please see Customizing Linux CVM Configurations.
    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, the client is installed successfully.

    Step 2. Connect to the instance

    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, the connection command should be as follows:

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


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

    Connecting Using DMC

    You can use Tencent Cloud DMC to access TencentDB for Redis instances, manipulate databases and tables, manage instance sessions, monitor instances in real time, view InnoDB lock waits, and use the SQL window.

    Connecting Using SDKs

    For more information, please see SDK Connection.
