Last Updated: Jun 07, 2019

This section describes the configuration of security groups in DMS.

Prerequisites

  • You have access permissions to DMS and you have logged on to the DMS console.

Procedure: Global settings

  1. Log on to the DMS console and click Security Group Settings in the upper-right corner.

  2. Click Global Settings, select Allow or Not Allow based on your needs, and click OK to save the settings.

    Notes

    • AllowWhen Allow is selected, DMS can automatically configure security groups for ECS instances. You need to activate AliyunDMSDefaultRole first.

    • Not AllowWhen Not Allow is selected, DMS may be rejected when attempting to log on to ECS instances or databases that are deployed on ECS instances, and you will need to manually configure security groups and specify access rules.

Procedure: Access rule settings

  1. Log on to the DMS console and click Security Group Settings in the upper-right corner.

  2. On the Access Rule Settings page, change access rules based on your needs and click OK to save the settings.

    Notes

    The Access Rule Settings page contains the following parameters:

    • Region: For example, China (Shenzhen), China (Qingdao), and China (Beijing).

    • Security Group ID/Name: Existing security groups.

    • Add Access Rule: Private Network/Public Network. If selected, the CIDR block of DMS is added to the specified security group, which allows DMS to access ECS instances.
