Cloud terminal processing method and system based on read-write separation

Abstract

The invention specifically relates to a cloud terminal processing method and system based on read-write separation. The technical problem to be solved is to provide the cloud terminal processing method and system which can realize the read-write separation at an operating system level, do not need to change the configuration of a read-write area, cannot affect the operation of a cloud terminal, and are based on the read-write separation. The adopted technical scheme includes the following steps: partitioning a storage device to obtain a rootfs image and a boot partition image; establishing anOverlay partition; re-combining the rootfs image subjected to mirroring by the system with the Overlay partition to obtain a file system with read-write separation; and mounting the file system with read-write separation. The invention is applicable to the field of computers.

Description

technical field [0001] The invention belongs to the technical field of cloud terminal processing, and in particular relates to a cloud terminal processing method and system based on read-write separation. Background technique [0002] The current cloud computing field is developing rapidly. The cloud desktop field centralizes the management of computer desktops, improves the management and maintenance efficiency of computing equipment, and greatly reduces the cost of operation and maintenance. As a user-oriented cloud terminal, it has the advantages of low hardware cost, low energy consumption, and convenient centralized management. Cloud desktop is a computer desktop environment under centralized management. Users access the computer desktop environment through cloud terminals, and managers manage cloud desktops through the cloud desktop management platform. [0003] The local operating system of the cloud terminal is called the host operating system, and the user's access...

Problems solved by technology

The operation process is complicated, which will affect the normal operation of the system, and in the read-only state, it will affect the normal writing requirements of the system

[0008] In the existing technology, Squashfs can also be used to build a Linux read-write file system, based on the squashfs read-only image, create a writable file, and mount it as a loop device during initrd loading, and use the snapshot mechanism of device-mapper to realize On the basis of the original read-only image, the system is writable. Through the snapshot mechanism of device-mapper, the loop file is established as its writable part. The implementation of this solution is relatively complicated, because the writable area is a single file Limited by the size of the file, the part of the writable area is limited, and it is mounted through the loop device, which increases the number of layers loaded by the device and affects the writing performance
