Configuring DCS Redis ACL Users

Prerequisites

By default, this function is supported by DCS Redis 4.0/5.0 instances. To use this function for DCS Redis 6.0 instances, contact customer service to enable the whitelist and upgrade the instance engine.

This function can only be enabled for DCS Redis professional instances with a password and is not supported for DCS Redis professional instances with Password Protected disabled.

Configuring DCS Redis ACL Users

1. Log in to the DCS console.
2. Click in the upper left corner of the management console and select the region where your instance is located.
3. In the navigation pane, choose Cache Manager.
4. Click an instance.
5. Choose User Management in the navigation pane.

   The user whose username is default is the instance's default user. The default user has read and write permissions and their password is the instance's password.

6. Click Create User.
   

   • A maximum of 18 users can be created for an instance.
   • If Password Protected is enabled for a DCS Redis instance, only the default user can be used.
   • To use a normal user, click Reset Password in the row that contains the default user to disable Password Protected for the default user.

7. Specify the Username and Description. Select Read-only or Read/Write. Specify the Password and confirm it.
8. Click OK.
   

   A normal ACL user connects to an instance with password {username:password}.

   • When using redis-cli to connect to an instance, the default user runs the following command:

     ./redis-cli -h {dcs_instance_address} -p 6379 -a {password}

   • A normal ACL user runs the following command:

     ./redis-cli -h {dcs_instance_address} -p 6379 -a {username:password}
