Problems solved by technology

At present, the method of using the CephFS file system for the virtual machine in the virtual environment either has a huge security risk, or the network topology is complex, or the integration level is not high, which is inconvenient for management and maintenance.

Embodiment Construction

[0031] The core of the present invention is to provide a system for safely mounting a distributed file system. In the prior art, at present, there are three main methods for virtual machines in a virtualized environment to use the CephFS file system: the first method is to use the CephFS file system directly. The Guest system, as a client of CephFS, can be directly accessed through Ceph-fuse or Ceph kernel module CephFS cluster, this method of use directly exposes the underlying Ceph cluster authentication information to tenant access, and requires tenant virtual machines to communicate with the Ceph network, which poses a huge security risk. Therefore, cloud platform manufacturers cannot use this method. The second is the indirect use of NFS protocol conversion. NFS-Ganesha is an NFS-based open source file server that supports multiple storage backends. Export CephFS to NFS through NFS-ganesha, use the NFS client to mount the NFS exported by NFS-ganesha inside the virtual mac...

Abstract

The invention discloses a system for safely mounting a distributed file system. The system comprises a VFS layer, a driving layer and a virtual machine monitor layer, the driver layer comprises a front-end driver and a rear-end driver which are in communication connection with each other, and the virtual machine monitor layer is provided with a client; the VFS layer and the front-end driver are located at a guest end, a file system of a distributed cluster corresponding to a client is mounted on the VFS layer, and the front-end driver is used for driving the VFS layer; the back-end driver and the virtual machine monitor layer are located at the host end, the back-end driver is used for driving the client, the client is in direct communication connection with the distributed cluster, and the virtual machine monitor layer shields authentication information of the distributed cluster from the client at the guest end. The system has the advantages of high security and simple structure, can realize the read-write function of data only by using fewer resources, and is convenient to manage and maintain. The invention also provides a method which also has the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a system for safely mounting a distributed file system and a method for safely mounting a distributed file system. Background technique [0002] A hypervisor is an intermediate software layer that runs between the underlying physical server and the operating system, allowing multiple operating systems and applications to share hardware. It can also be called VMM (virtual machine monitor), that is, a virtual machine monitor. Hypervisor is the core of all virtualization technologies. According to different hypervisors, virtualization is divided into type I virtualization and type II virtualization. Among them, type I virtualization means that the virtual machine runs directly on the system hardware and creates a full hardware simulation instance, which is called "bare metal" type; type II virtualization means that the virtual machine runs on the traditional operating syste...
