:Use a public endpoint to connect to a Tair instance

Usage notes

• You are not charged traffic fees when you connect to your Tair instance over the Internet. However, this increases network latency, compromises service performance, and results in security risks. We recommend that you connect to instances by using Virtual Private Cloud (VPC) for lower network latency and higher security.

  Note

  The Service Level Agreement (SLA) does not apply to client exceptions caused by the Internet conditions.

• Public endpoints are not supported for Tair cloud-native cluster instances that run in direct connection mode. You can connect to these instances over a VPC.

Procedure

1. Obtain the public IP address of your on-premises device.

   • Linux: Open the CLI, enter the curl ifconfig.me command, and then press Enter.

   • Windows: Open Command Prompt, enter the curl ip.me command, and then press Enter.

   • macOS: Start Terminal, enter the curl ifconfig.me command, and then press Enter.

2. Add the public IP address of your on-premises device to a whitelist of the Tair instance. For more information, see Configure whitelists.

   Note

   If your on-premises device uses dynamic IP addresses, you can add the CIDR block to a whitelist of the Tair instance to prevent access failures caused by IP address changes. This may compromise the security of the instance. Proceed with caution.

3. Apply for a public endpoint for the Tair instance. For more information, see Apply for a public endpoint for an instance.

4. Use the redis-cli tool or a client program to connect to the Tair instance based on the obtained public endpoint.

   • Use redis-cli to connect to a Tair instance

   • Use a client to connect to a Tair instance

   Note

   When you use a public endpoint to connect to your instance, you must specify the database account and the corresponding password. For more information, see Connect to a Tair instance.
