:RDS secondary database creation on ECS instances

Last Updated:Sep 27, 2020

Introduction 

This article describes how to create an RDS secondary database on an ECS instance.

 

Background

You cannot build Secondary databases on ECS instances for the following reasons:

  • Apsaradb for RDS uses the primary-secondary HA architecture, so you do not open configuration information and permissions of database files to clients.
  • When an exception occurs on the primary database, the secondary database switches to the primary database within 30 seconds, which causes the serverid to change.

 

Application scope

  • ApsaraDB RDS for MySQL
