Maintaining the Manageability of Your Database Deployments

The following best practices will ensure that your database deployments on MySQL Cloud Service stay manageable.

To keep your database deployments manageable, follow these guidelines:

• Do not disable or close access to the SSH port (port 22).

  You can open other ports and protocols. See About Network Access to MySQL Cloud Service for information about the available options.

• Do not detach, change file access permissions for, or change the mount point of any storage volume attached to a compute node during the creation of your database deployment. In particular, do not unmount or change the file access permissions of /u01 through /u05.
• Do not change compute node OS users and SSH key settings that were configured during the creation of your database deployment.
• Apply only patches that are available through MySQL Cloud Service. Do not apply patches from any other source unless directed to by Oracle Support.
