Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
At present, the technical scheme for automatically deploying the operating system by the ARM server generally adopts a network card PXE (preboot execution environment) to start, and in combination with some other services and configurations, installation and deployment of the operating system can be completed without human intervention. IT architecture in the financial industry is usually based on stability, and therefore, in a network architecture, a group of TORs (Top of Rack, a data center wiring manner) is usually adopted to correspond to an independent small network segment to achieve the purpose of reducing the fault influence range.
For a web server, when allocating an IP to an ARM (Advanced RISC Machine, low power consumption and low cost processor using a reduced instruction set) client server that needs to deploy an operating system, each group of TORs has a limited disposable IP pool of a dynamic host configuration protocol, and when there is a deployment demand for the operating system for a large number of ARM servers at the same time, a queuing and current limiting situation occurs, which affects the deployment efficiency of the servers. In an actual application scenario, the data center has many TORs corresponding to the TORs, each group of token buckets is set with a timer, and deployment efficiency may be affected in a high concurrency scenario.
For the ARM client itself, after the IP is allocated, an operating system is usually deployed locally in a ks + ISO manner, and since a source ISO file contains all contents, which is usually large, the file transmission speed is slow, which results in a long IP resource occupation time of a dynamic host configuration protocol DHCP, even if a mainstream P2V (migration of a physical machine to a virtual machine) migration principle is adopted, since the image file only supports a Boot manner of MBR (Master Boot Record), the image file must contain a root partition and MBR. Therefore, when the system disk of the target operating system usually needs to be copied in the whole disk, it is still not beneficial to compress the size of the image file, and further the deployment efficiency of the whole machine is affected.
All the situations reflect that the existing deployment efficiency of operating system deployment modes for large-scale ARM servers is low.
In order to solve the above problems, the present invention provides a method for deploying an operating system, that is, for an ARM client, the method provides conditions for getting rid of the source installation mode of the client by installing a boot tool before a server generates a mirror package of a target operating system; the method has the advantages that the size of the mirror image file is effectively reduced by removing unnecessary files and then packaging the unnecessary files to generate a mirror image packet to be sent to the client, so that large files do not need to be transmitted in the mirror image cloning process, the target operating system can be more quickly deployed by means of the starting guide tool and the mirror image cloning mode when the subsequent client deploys a local system, the source generation installation mode and the limited MBR guide mode of the client can be thoroughly eliminated, the time for occupying DHCP IP resources is reduced compared with the source generation installation mode, and the deployment efficiency of the whole machine is improved; for a web server, the invention confirms whether to pass through the system deployment request of each client through a token bucket algorithm which can dynamically record the time interval generated by the token, and can realize the flexible and configurable queuing current-limiting function without a timer, so that the batch deployment task of the operating systems of a plurality of clients can be efficiently completed under the condition of limited IP pool; in conclusion, the invention solves the technical problem of low deployment efficiency of operating system deployment modes of large-scale ARM servers.
As shown in fig. 1, fig. 1 is a schematic device structure diagram of a hardware operating environment according to an embodiment of the present invention.

The network interface 1004 may optionally include a standard wired interface, a wireless interface (e.g., WI-FI interface). The memory 1005 may be a high-speed RAM memory or a non-volatile memory (e.g., a magnetic disk memory). The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration of the apparatus shown in fig. 1 is not intended to be limiting of the apparatus and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a kind of computer storage medium, may include therein an operating system, a network communication module, a user interface module, and an operating system deployment program.
In the device shown in fig. 1, the network interface 1004 is mainly used for connecting to a backend server and performing data communication with the backend server; the user interface 1003 is mainly used for connecting a client (programmer's end) and performing data communication with the client; and processor 1001 may be configured to call an operating system deployment program stored in memory 1005 and perform the operations of the operating system deployment method described below.
Based on the above hardware structure, an embodiment of the operating system deployment method of the present invention is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of the method for deploying an operating system according to the present invention, where the method is applied to a web server, and the method includes:
step S10, after installing a preset boot tool in a target operating system, acquiring a system key file of the target operating system;
step S20, excluding unnecessary files in the system key files, and compressing and packaging the system key files except the unnecessary files to obtain a system mirror image package;
in the embodiment, the method is applied to the web server. The start-up guidance tool includes grub2-efi tools. The target operating system (target OS) refers to an operating system that an ARM client requests to deploy. The system key file refers to a key file of the target operating system. Unnecessary files may be pre-specified by the relevant personnel.
It should be noted that, the existing mainstream P2V (physical machine migration to virtual machine) migration principle relates to packed migration of a system, and a simple system image installation process thereof is as follows:
firstly, verifying that the position and the authority of a system key file of a target OS are correct and can be read and written normally;
second, a system command tool dd is used to make a partition copy of the system disk sda, and an image file is exported, such as:
ddif=/dev/sdaof=/mnt/kylin_os.imagebs=1Kcount=$count
the number of partitions to be copied is represented by the number of the $ count, or full disk copying may be selected, the system command tool fdisk may be used to check specific partition information of the system disk sda, the derived mirror image at least needs to include a root partition and an MBR, and a lack of the MBR may cause the system to be unable to be started normally;
thirdly, the client deploys a slave network card to start to enter the PXE environment for the first time;
fourthly, in the PXE environment, the client downloads the image file from the server, such as: image;
fifthly, in the PXE environment, the client reads the content of the image file through a system command tool dd and restores the content of the image file to the sda disk;
and sixthly, the client rebot is restarted to enter a new system, and the whole deployment process is completed.
The present invention considers that the partition copy is performed by using the system command tool dd, and only supports the boot mode of the MBR, and the image file must include the root partition and the MBR. Therefore, when the first hard disk sda of the target OS has no specific partition, the entire disk copy is usually required, which is not favorable for compressing the size of the image file, and only supports the boot mode of the MBR, which is poor in flexibility. A boot toolkit based on a mainstream Extensible Firmware Interface (EFI) mode is installed in a target OS through a server, all system key files of the target OS are obtained, unnecessary files in the system key files are eliminated, then the rest files are compressed and packaged, and the packaged file package is used as a system image package of the target OS. When the ARM client needs to deploy the target OS, the tool can be used for booting in a mainstream EFI mode, and a traditional MBR boot mode is not relied on; and only necessary directories are compressed and packed, so that the size of the mirror image file is effectively reduced.
In addition, before step S10, the server may check whether the key file location and the authority of the target operating system are correct, and may read and write normally, if yes, step S10 is performed; if not, generating and outputting corresponding error notification information.
Step S30, when a system deployment request sent by an ARM client is received, the request is confirmed to pass through based on a preset token bucket algorithm, wherein the token bucket algorithm dynamically records the time interval of token generation;
in the present embodiment, for the token bucket algorithm, as shown in fig. 3. Assuming that there are 10 IP pools for which TOR1 is available to be dominated by DHCP, the upper token limit b of token BUCKET group BUCKET1 is set to 10. Assuming that the DHCP sets an IP lease time of 1800s (which depends on the time required for a single server deployment), the token generation speed r is 1/1800toekn/s, and the time interval t for token generation waiting is 1800 s. When the TOR1 has n servers requesting deployment at the same time, when n < ═ BUCKET1 has the remaining number of tokens, directly entering deployment and deleting n tokens; when n > BUCKET1 has the remaining token number, the exceeding part is in a token generation waiting token wait state, and the others enter deployment; the server in token wait state keeps trying at a time interval t until deployment is entered.
Because the data center has a plurality of TORs corresponding to the TORs, and each group of token buckets is provided with a timer, the performance of the system may be reduced in a high-concurrency scene; the token is put at a certain token production speed and works by depending on the timer, so that the dependence on the time timer is further increased; in addition, under a distributed architecture, consistency is kept among multiple nodes, higher requirements are placed on time accuracy, and program logic is prone to defects due to time errors. Therefore, the embodiment improves the original token bucket algorithm, cancels the setting of the timer, and dynamically records the next token generation time of each group of token buckets, thereby realizing the flexible and configurable queuing current-limiting function, reasonably utilizing the limited resources and realizing the batch concurrent deployment.
Step S40, sending the system image package to the client, so that the client completes the deployment of the target operating system according to the deployment manner of image clone and based on the boot tool.
In this embodiment, the server sends the system image package and other required files to the client, and after acquiring the image package of the target OS, the client decompresses and copies the image package to the designated file system partition, and then executes a subsequent installation process by using a boot startup tool grub2-efi preinstalled in the image package, so as to complete the target OS deployment on the client.
The embodiment provides an operating system deployment method. For the ARM client, a boot starting tool is installed before a mirror image package of a target operating system is generated at a server, so that a condition is provided for getting rid of a source installation mode of the client; the method has the advantages that the size of the mirror image file is effectively reduced by removing unnecessary files and then packaging the unnecessary files to generate a mirror image packet to be sent to the client, so that the larger files do not need to be transmitted in the mirror image cloning process, the subsequent client can complete the deployment of the target operating system more quickly by means of the starting guide tool and according to the mirror image cloning mode when deploying the local system, the source generation installation mode and the limited MBR guide mode of the client can be thoroughly eliminated, the restarting times in the deployment process can be shortened compared with the source generation installation mode, and the time for occupying DHCP IP resources is reduced, so that the deployment efficiency of the whole machine is improved; for a web server, the invention confirms whether to pass through the system deployment request of each client through a token bucket algorithm which can dynamically record the time interval generated by the token, and can realize the flexible and configurable queuing current-limiting function without a timer, so that the batch deployment task of the operating systems of a plurality of clients can be efficiently completed under the condition of limited IP pool; in conclusion, the invention solves the technical problem of low deployment efficiency of operating system deployment modes of large-scale ARM servers.
Further, a second embodiment of the operating system deployment method of the present invention is proposed based on the first embodiment shown in fig. 2. In the present embodiment, step S30 includes:
step S31, when a system deployment request sent by the client is received, querying the residual token number stored in a Redis database of remote dictionary service based on the token bucket algorithm, wherein the Redis database stores the residual token number of the token bucket group and the next token generation time;
step S32, judging whether the number of the remaining tokens meets a preset number condition;
step S33, if yes, passing the request and consuming a specified number of tokens;
and step S34, updating the residual token number stored in the Redis database to the residual token number after the request is consumed, and updating the next token generation time according to the current time and the preset token production rate.
In this embodiment, the server instead uses the redis database record to dynamically record the next token generation time for each group of token buckets. The preset number condition may be that the number of remaining tokens is greater than or equal to a preset number of tokens. The designated number can be flexibly set according to actual conditions.
As an embodiment, a schematic diagram of a distributed architecture is shown in fig. 4. The method comprises the steps that a request sent by a PC end is transmitted to a server end comprising a plurality of service servers through a load balancing strategy, and the server end centrally stores the residual token quantity of each token bucket group and the next token generation time through a Redis database. For example:
Key | Value |
TOKEN_BUCKET1_NEXT_AVAILABLE_TIME | 2021-9-15 10:22:30 |
TOKEN_BUCKET2_NEXT_AVAILABLE_TIME | 2021-9-15 10:32:30 |
|
10 |
TOKEN_BUCKET2_COUNT | 8 |
the server first queries the number of TOKENs TOKEN _ TOKEN 1_ COUNT remaining in the first TOKEN BUCKET group TOKEN 1 when receiving the request:
if TOKEN _ TOKEN 1_ COUNT >1, the request passes, consuming one TOKEN, -the number of remaining TOKENs of TOKEN 1 is decremented by 1(TOKEN _ TOKEN 1_ COUNT-1);
if TOKEN _ TOKEN 1_ COUNT is equal to 1, the request is passed, one TOKEN is consumed, the number of remaining TOKENs of TOKEN 1 is decreased by 1, and the NEXT TOKEN generation TIME of TOKEN 1(TOKEN _ TOKEN 1_ NEXT _ AVAILABLE _ TIME) is updated to the CURRENT TIME CURRENT _ TIME + r (TOKEN/s). Wherein r is a preset token production rate and can be flexibly adjusted according to actual requirements.
Further, after step S32, the method further includes:
step S35, if not, suspending the request and inquiring the next token generation time stored in the Redis database;
step S36, determining whether the current time is greater than the next token generation time;
step S37, if yes, passing the request and consuming a specified number of tokens;
