Constraint

TaurusDB access

  • If TaurusDB instances are not bound with EIPs, the instances must be in the same VPC subnet as the ECSs associated with these instances.

  • Security group rules must be added to allow ECSs to access TaurusDB instances.

    By default, a TaurusDB instance cannot be accessed by an ECS in a different security group. To allow it, you must add an inbound rule to the TaurusDB security group.

  • The default TaurusDB instance port is 3306. You can change it if you want to access TaurusDB through another port.

Deployment

ECSs in which TaurusDB instances are deployed are not visible to users. You can access TaurusDB instances only over an IP address and a port.

Administrator root permission

Only the root user permissions are available on the instance creation page.

Database parameter modification

Most parameters can be modified on the TaurusDB console.

Data migration

The mysqldump tool is used to migrate data to TaurusDB.

TaurusDB instance reboot

TaurusDB instances cannot be rebooted through commands. They must be rebooted on the TaurusDB console.

TaurusDB backup files

TaurusDB backup files are stored in OBS buckets and are not visible to users.
