Can I Customize or Change the Port for Accessing a DCS Instance?
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.
Public access is not supported by DCS Redis 4.0/5.0/6.0 instances.
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.
- In the navigation pane of the DCS console, choose Cache Manager.
- Click a DCS Redis instance.
- In the Connection area, click
next to Connection Address.
After the port is changed, all connections to the Redis instance are interrupted, and services are connected to the new port.
