Use a customized script-ApsaraDB for MyBase(MyBase)-阿里云帮助中心

A MyBase dedicated cluster grants you specific OS permissions on the host, which lets you upload and download files, and install software. This topic shows you how to install and use a customized script.

Background

Unlike a traditional cloud database, which does not provide backend access to your own management center, a MyBase dedicated cluster lets you log on to the host with OS permissions. You can connect the host to your management center for centralized administration. You can use a bastion host to log on to and manage the database instance host. This lets you install a customized script on the host to collect system information and meet specific requirements.

Note

For details on available host permissions, see Host permissions.
To learn how to create and use a bastion host, see Create a bastion host and Connect to a host from a bastion host (Linux).

Procedure
