Key Concepts of Virtualmin Sub-servers:
- Isolation: Each sub-server gets its own administration user, databases, email accounts, and FTP users, providing strong separation from the parent.
- Shared Foundation: They still run under the parent’s core Unix user and group, which helps with system resource management and permissions.
- Management: You manage them like any other Virtualmin server, but they appear nested under the parent in the server list.
- Use Cases: Perfect for hosting different WordPress sites on
blog.example.com,shop.example.com, or even completely different domains likemy-other-site.comunder the same parent account.
