Can I Customize or Change the Port for Accessing a DCS Instance?

Updated on 2024-09-24 GMT+08:00

You cannot customize or change the port for accessing a DCS Redis 3.0, 6.0 professional, or Memcached instance. You can customize and change the port for accessing a DCS Redis 4.0, 5.0, or 6.0 basic instance.

  • Redis 3.0

    Intra-VPC access: port 6379; public access without SSL: port 6379; public access with SSL: port 36379.

  • Memcached

    Use port 11211 for intra-VPC access. Public access is not supported.

  • Redis 4.0/5.0/6.0

    You can specify a port (ranging from 1 to 65535) or use the default port (6379) for accessing a DCS Redis 4.0/5.0/6.0 basic edition instance. If no port is specified, the default port will be used.

    For Redis 6.0 professional edition, you cannot customize a port. The default port 6379 will be used.

If the instance and the client are in different security groups, you must configure access rules for the security groups, allowing access through the specified port. For details, see How Do I Configure a Security Group?

Customizing a Port

When creating a DCS Redis 4.0, 5.0, or 6.0 basic edition instance, you can enter a port number for IP Address. If you do not specify a port, the default port 6379 is used.

Changing the Port

After a DCS Redis 4.0, 5.0, or 6.0 basic instance is created, you can change its port.

  1. In the navigation pane of the DCS console, choose Cache Manager.
  2. Click a DCS Redis instance.
  3. In the Connection area, click next to Connection Address.
    NOTICE:

    After the port is changed, all connections to the Redis instance are interrupted, and services are connected to the new port.
