Embodiment 1

[0063] This example discloses a specific implementation of a method for building a computing cluster based on a diskless system (hereinafter referred to as "method").

[0064] Please refer to Figure 5 and Image 6 , Figure 5 is an application flowchart of an embodiment of the present invention; Image 6 It is a structural schematic diagram of the computing cluster of the present invention. like Figure 5 and Image 6 As shown, in the implementation of the construction method of the present invention, the kernel and the initramfs are loaded into the memory through the Boot loader, and the initramfs is decompressed and simulated as a file system in the memory, and the kernel can load init and switch to the real rootfs.

[0065] Running GNU / Linux systems on dedicated embedded boards has become increasingly popular. An embedded Linux system can usually be divided into four levels from the software point of view: [2]

[0066] 1. Bootloader. Including the boot code (option...

Embodiment 2

[0087] Please refer to image 3 , image 3 It is a structural schematic diagram of the building system of the computing cluster of the present invention. like image 3 As shown, a computing cluster building system of the present invention, wherein, based on the diskless system, the building system includes:

[0088] Starting module, described starting module loads kernel and initramfs in memory by Boot loader;

[0089] Loading module, the loading module simulates a file system in the memory after decompressing the initramfs, and switches the kernel loading init to rootfs;

[0090] A running module, after the network is started, the running module loads the system image into the memory through the node to run;

[0091] A building module. After the new server is powered on, the building module enters the memory operating system. After the nodes are started, they communicate according to the assigned IP to form a computing cluster.

[0092] Further, the loading module includ...

Embodiment 3

[0099] combine Figure 4 As shown, this embodiment discloses a specific implementation manner of a computer device. The computer device may comprise a processor 81 and a memory 82 storing computer program instructions.

[0100] Specifically, the processor 81 may include a central processing unit (CPU), or an Application Specific Integrated Circuit (ASIC for short), or may be configured to implement one or more integrated circuits in the embodiments of the present application.

[0101] Among them, the memory 82 may include mass storage for data or instructions. For example without limitation, the memory 82 may include a hard disk drive (Hard Disk Drive, referred to as HDD), a floppy disk drive, a solid state drive (SolidState Drive, referred to as SSD), flash memory, optical disk, magneto-optical disk, magnetic tape or universal serial bus (Universal Serial Bus, referred to as USB) drive or a combination of two or more of the above. Storage 82 may comprise removable or non-rem...

Abstract

The invention discloses a computing cluster building method and system, computer equipment and a storage medium. The building method is based on a diskless system and comprises the following steps: a starting step: kernel and initramfs are loaded into a memory through a Boot loader; a loading step: after the initramfs is decompressed, the initramfs is simulated into a file system in the memory, and the kernel is loaded with init and switched into rootfs; a running step: after the network is started, the system mirror image is loaded into the memory for running through the node; and a building step: after the new server is electrified, the new server enters a memory operating system, and after the nodes are started, communication is carried out according to the distributed IP to form a computing cluster. According to the invention, hardware cost is saved, and later management and maintenance are facilitated.

Description

technical field [0001] The invention belongs to the field of methods for building computing clusters, and in particular relates to a method, system, computer equipment and storage medium for building a computing cluster based on a diskless system. Background technique [0002] A diskless system (diskless) means that there is no need to install a physical hard disk on the server, and its file system image is uniformly maintained by the network server. When starting up, you only need to load the remote file system image to the local through HTTP or NFS (Network File System). use. [0003] With the development of 10 Gigabit networks and the reduction of CPU memory costs, hard disk reading and writing has become the most important factor affecting computing speed. [0004] The computing cluster based on the diskless system does not depend on the hard disk, all the data is transmitted through the network, and the system is loaded into the memory to run, which can greatly improve...
