Bare-metal deployment method, apparatus, equipment, and media based on three-layer network

Abstract

This application relates to the field of software development technology, specifically disclosing a bare metal deployment method, apparatus, device, and medium based on a three-tiered network. By implementing a three-tiered deployment network for bare metal, this application goes beyond the traditional two-tiered network architecture, improving the large-scale support capability of the cluster at the network layer. This solves the problem of limited bare metal cluster size, significantly increasing the size of bare metal servers and enhancing support capabilities in ultra-large cluster scenarios. Furthermore, dividing the three-tiered network into layers using LEAFs (Levels of Af) provides greater flexibility in cluster deployment. Each LEAF is independent, and subsequent expansion only requires expanding the corresponding bare metal cluster by LEAF, ensuring scalability and ease of expansion. On the other hand, customized DHCP enables cross-collision domain communication for bare metal in ultra-large clusters; only one DHCP service is needed per cluster, reducing maintenance costs and resource overhead.

Description

Technical Field

[0001] This application relates to the field of software development technology, and in particular to a bare metal deployment method, apparatus, computer equipment, and storage medium based on a three-tier network. Background Technology

[0002] In traditional bare metal application scenarios, bare metal components are typically deployed within the same Layer 2 network, communicating with each other through this network. Layer 2 networks can achieve communication using only MAC addressing, but this is only suitable for applications within the same collision domain. Due to the inherent limitations of Layer 2 networks, a single cluster can only support a maximum of around 10,000 server nodes, thus restricting the scalability of bare metal clusters. Therefore, improving the scalability of bare metal clusters has become a pressing issue. Summary of the Invention

[0003] This application provides a bare metal deployment method, apparatus, computer equipment, and storage medium based on a three-layer network to improve the scale of bare metal clusters.

[0004] In a first aspect, this application provides a bare-metal deployment method based on a three-layer network, the method comprising:

[0005] Upon receiving the deployment instruction for the bare metal service, the system initiates the first Dynamic Host Configuration Protocol (DHCP) request based on the bare metal server in the bare metal service deployment system.

[0006] The first DHCP request is received by the uplink switch, and the response result of the first DHCP request is obtained by the DHCP server.

[0007] Based on the bare metal server and the response result, configure the IP address and cross-network segment routing;

[0008] Based on the IP address, cross-network segment routing, and the image file address in the response result, the image file is requested from the image server, and the image file is installed to complete the bare metal deployment.

[0009] Furthermore, before initiating the first Dynamic Host Configuration Protocol (DHCP) request based on the bare metal server in the bare metal service deployment system upon receiving the bare metal service deployment instruction, the process further includes:

[0010] Based on the aggregation switch, uplink switch, DHCP server, and bare metal server, a bare metal service deployment system based on a three-tier network structure is generated.

[0011] Furthermore, the aggregation switch is used to enable communication between the uplink switch, the DHCP server, and the bare metal server.

[0012] Further, the step of receiving the first DHCP request based on the uplink switch and obtaining the response result of the first DHCP request based on the DHCP server includes:

[0013] Based on the uplink switch receiving the first DHCP request, and adding the target gateway address to the first DHCP request, a second DHCP request is obtained;

[0014] Based on the second DHCP request, obtain a usable IP address to be used;

[0015] Based on the image file address and the IP address to be used, generate the response result of the first DHCP request;

[0016] The DHCP server returns the response result of the first DHCP request to the bare metal server.

[0017] Further, obtaining an available IP address based on the second DHCP request includes:

[0018] Based on the uplink switch, the second DHCP request is forwarded to the DHCP server;

[0019] Based on the DHCP server parsing the second DHCP request, the target gateway address is obtained, and the database is queried to see if there is an address pool corresponding to the target gateway address;

[0020] When an address pool corresponding to the target gateway address exists, the IP address to be used is obtained from the address pool.

[0021] Furthermore, after querying the database to see if an address pool corresponding to the target gateway address exists, the process further includes:

[0022] If the database does not contain an address pool corresponding to the target gateway address, obtain the configuration file;

[0023] Based on the configuration file, obtain the total classless inter-domain route (cidr) and the address segment division length corresponding to the target deployment network;

[0024] Based on the total CIDR and the partition length, an address pool corresponding to the target gateway address is obtained, so that the IP address to be used can be obtained from the address pool.

[0025] Further, obtaining the address pool corresponding to the target gateway address based on the total CIDR and the partition length includes:

[0026] Based on the partition length, the total CIDR is divided into at least one sub-address segment;

[0027] The last sub-address segment in at least one of the sub-address segments is used as the address pool corresponding to the target gateway address, and the correspondence between the target gateway address and the last sub-address segment in the sub-address segments is stored in the database.

[0028] Secondly, this application also provides a bare metal deployment device based on a three-layer network, the device comprising:

[0029] The first DHCP request initiation module is used to initiate a first Dynamic Host Configuration Protocol (DHCP) request based on the bare metal server in the bare metal service deployment system when a deployment instruction for the bare metal service is received.

[0030] The response result acquisition module is used to receive the first DHCP request based on the uplink switch and obtain the response result of the first DHCP request based on the DHCP server;

[0031] The configuration module is used to configure the IP address and cross-network segment routing based on the bare metal server and the response result;

[0032] The image file installation module is used to request an image file from the image server based on the IP address, cross-network segment routing, and the image file address in the response result, and to install the image file to complete the bare metal deployment.

[0033] Thirdly, this application also provides a computer device, the computer device including a memory and a processor; the memory is used to store a computer program; the processor is used to execute the computer program and, when executing the computer program, implement the bare metal deployment method based on a three-layer network as described above.

[0034] Fourthly, this application also provides a computer-readable storage medium storing a computer program that, when executed by a processor, causes the processor to implement the bare metal deployment method based on a three-layer network as described above.

[0035] This application discloses a bare metal deployment method, apparatus, computer equipment, and storage medium based on a three-tier network. Upon receiving a bare metal service deployment instruction, the system initiates a first Dynamic Host Configuration Protocol (DHCP) request based on the bare metal server in the bare metal service deployment system. The system receives the first DHCP request via an uplink switch and obtains the response result from the DHCP server. Based on the bare metal server and the response result, it configures IP addresses and cross-network segment routes. Based on the IP addresses, cross-network segment routes, and the image file address in the response result, it requests an image file from an image server and installs the image file to complete the bare metal deployment. The bare metal service deployment system of this application is based on a three-tier network. By making the bare metal deployment network three-tiered, the three-tier network requires cross-network segment communication via IP routing, thus enabling communication across multiple collision domains. This improves the large-scale cluster support capability at the network level, solving the problem of limited bare metal cluster size and significantly increasing the size of bare metal servers, enhancing support capabilities in ultra-large cluster scenarios. On the other hand, customized DHCP enables bare metal cross-collision domain communication in ultra-large clusters; only one DHCP service needs to be used in a cluster, reducing maintenance costs and resource overhead.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0047] It should also be understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0048] This application provides a method, apparatus, computer device, and storage medium for bare metal deployment based on a three-tier network. The bare metal deployment method based on a three-tier network can be applied to servers, deploying bare metal services through a three-tier network structure, thereby increasing the scale of the bare metal cluster. The server can be a standalone server or a server cluster.

[0049] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0050] Please see Figure 1 , Figure 1This is a schematic flowchart illustrating a bare metal deployment method based on a three-tier network, provided in an embodiment of this application. This bare metal deployment method based on a three-tier network can be applied to servers to deploy bare metal services through a three-tier network structure, thereby increasing the scalability of bare metal clusters.

[0051] like Figure 1 As shown, the bare metal deployment method based on a three-layer network specifically includes steps S101 to S104.

[0052] S101. Upon receiving the deployment instruction for the bare metal service, initiate the first Dynamic Host Configuration Protocol (DHCP) request based on the bare metal server in the bare metal service deployment system.

[0053] In specific embodiments, such as Figure 2 As shown, when a bare metal server initiates a DHCP request through port 67, the request will have the gateway address added to it when it passes through the uplink leaf, and the request will be forwarded to the DHCP service address.

[0054] Furthermore, before initiating the first Dynamic Host Configuration Protocol (DHCP) request based on the bare metal server in the bare metal service deployment system upon receiving the bare metal service deployment instruction, the process further includes: generating a bare metal service deployment system based on a three-tier network structure, based on the aggregation switch, uplink switch, DHCP server, and the bare metal server.

[0055] Furthermore, the aggregation switch is used to enable communication between the uplink switch, the DHCP server, and the bare metal server.

[0056] In one embodiment, such as Figure 3 As shown, the deployment system architecture for bare metal services is roughly as follows:

[0057] 1. Each leaf is connected to a set of switches, and each switch is connected to a corresponding bare metal server.

[0058] 2. Machines in different leaves need to communicate through a convergence switch.

[0059] 3. Each leaf switch is configured with a corresponding gateway address that has already opened a set of deployment network IPs, such as 192.168.64.0 / 26. At the same time, the corresponding DHCP (Dynamic Host Configuration Protocol) server addresses are configured on the switches, such as 192.168.0.1 and 192.168.0.2.

[0060] In one embodiment, a group of bare metal servers is placed under a single leaf, with bare metal servers within the same leaf belonging to the same Layer 2 network. Then, bare metal servers from different leaves are grouped into a Layer 3 network. This Layer 3 network scheme addresses the issue that bare metal servers cannot support large-scale application scenarios.

[0061] S102. Receive the first DHCP request based on the uplink switch, and obtain the response result of the first DHCP request based on the DHCP server;

[0062] In one embodiment, after receiving a request, the uplink switch first modifies the corresponding request packet by adding the target gateway address. Then, it forwards the request to the corresponding DHCP server according to the switch's configuration.

[0063] In one embodiment, such as Figure 2 As shown, when the DHCP server receives the first DHCP request, it parses the DHCP packet to obtain the corresponding gateway address. Simultaneously, it queries the database to check if the relay IP for the corresponding gateway address exists in the corresponding IP address pool. If it does, it retrieves the available IP address from the pool. After obtaining the IP address, it adds the corresponding gateway address to the routing information in the DHCP return result, along with the mirror path to be returned. Finally, it returns the response result of the first DHCP request to the bare metal server.

[0064] S103. Based on the bare metal server and the response result, configure the IP address and cross-network segment routing;

[0065] In one embodiment, after receiving the response to the first DHCP request, the bare metal server configures the IP address and cross-network segment routing.

[0066] In a specific embodiment, when the switch connected to the bare metal server receives the DHCP return result, it forwards the corresponding request to port 68 of the bare metal server. After receiving the DHCP return result, the bare metal server configures its IP address and configures cross-network segment routing.

[0067] S104. Based on the IP address, cross-network segment routing, and the image file address in the response result, request the image file from the image server and install the image file to complete the bare metal deployment.

[0068] In one embodiment, the image file is requested using the image file address returned by the first DHCP request, thus completing the bare metal deployment initialization process.

[0069] Please see Figure 4 , Figure 4This is a schematic flowchart illustrating a bare metal deployment method based on a three-tier network, provided in an embodiment of this application. This bare metal deployment method based on a three-tier network can be applied to servers to deploy bare metal services through a three-tier network structure, thereby increasing the scalability of bare metal clusters.

[0070] like Figure 4 As shown, the bare metal deployment method based on a three-layer network specifically includes steps S201 to S204.

[0071] S201. Based on the uplink switch receiving the first DHCP request, and adding the target gateway address to the first DHCP request, a second DHCP request is obtained;

[0072] S202. Based on the second DHCP request, obtain an available IP address to be used;

[0073] Further, obtaining an available IP address based on the second DHCP request includes: forwarding the second DHCP request to a DHCP server via the uplink switch; parsing the second DHCP request on the DHCP server to obtain the target gateway address, and querying the database to see if an address pool corresponding to the target gateway address exists; and if an address pool corresponding to the target gateway address exists, obtaining the IP address to be used from the address pool.

[0074] Furthermore, after querying the database to see if an address pool corresponding to the target gateway address exists, the process further includes: when no address pool corresponding to the target gateway address exists in the database, obtaining a configuration file; based on the configuration file, obtaining the total classless inter-domain route (CIDR) and the segment length of the address range corresponding to the target deployment network; and based on the total CIDR and the segment length, obtaining the address pool corresponding to the target gateway address, so as to obtain the IP address to be used from the address pool.

[0075] Further, obtaining the address pool corresponding to the target gateway address based on the total CIDR and the partition length includes: dividing the total CIDR into at least one sub-address segment based on the partition length; using the last sub-address segment among the at least one sub-address segment as the address pool corresponding to the target gateway address; and storing the correspondence between the target gateway address and the last sub-address segment among the sub-address segments in the database.

[0076] In one embodiment, such as Figure 5As shown, the process checks if the database contains IP address pool information corresponding to the target gateway. If it does, the service starts directly; otherwise, it initializes the IP pool, retrieves the configuration file, obtains the deployment network IP CIDR (e.g., 192.168.0.0 / 18), and the required segment length (e.g., 26 bits). Based on the configured total CIDR and address segment length, the IP address pool can be split into pools like 192.168.0.0 / 26 and 192.168.0.63 / 26, etc. The last segment is then set as the relay IP (i.e., the address pool corresponding to the target gateway address), for example, 192.168.0.62. The remaining available IPs are stored in the database as an allocable IP address pool.

[0077] S203. Based on the image file address and the IP address to be used, generate the response result of the first DHCP request;

[0078] S204. The response result of the first DHCP request is returned to the bare metal server based on the DHCP server.

[0079] In one embodiment, when DHCP receives a second DHCP request, it parses the DHCP packet to obtain the corresponding gateway address. Simultaneously, it queries the database to check if the relay IP for the corresponding gateway address exists in the corresponding IP address pool. If it does, it retrieves the available IP address from the pool. After obtaining the IP address, it adds the corresponding gateway address to the routing information in the DHCP response result, along with the mirror path to be returned. Finally, it returns the corresponding DHCP request result to the bare metal server.

[0080] In a specific embodiment, after the bare metal server receives the first DHCP request, the connected switch modifies the corresponding request packet, adds the trunk gateway address (i.e., the target gateway address) to the first DHCP request, generates a second DHCP request, and queries the DHCP service configuration address configured on the switch to forward the DHCP request to port 67 of the corresponding DHCP server.

[0081] In one embodiment, when the DHCP service receives a second DHCP request, it parses the corresponding request packet to obtain the corresponding relay gateway address, queries the database to see if there is a pool of IP addresses corresponding to the gateway, and retrieves a suitable IP address from the corresponding IP address pool.

[0082] If the network fails at a certain time, the corresponding relay gateway will be configured with cross-network segment routing. The IP address and image file address will be encapsulated into a DHCP request return packet and then returned via port 67.

[0083] In one embodiment, when the switch connected to the bare metal server receives the DHCP return result, it forwards the corresponding request to port 68 of the bare metal server.

[0084] In one embodiment, after the bare metal server receives the DHCP return result, it configures the IP address and configures cross-network segment routing.

[0085] Please see Figure 6 , Figure 6 This application provides a schematic block diagram of a bare metal deployment apparatus based on a three-tier network, which is used to execute the aforementioned bare metal deployment method based on a three-tier network.

[0092] The bare metal service deployment system generation module is used to generate a bare metal service deployment system based on a three-tier network structure, based on the aggregation switch, uplink switch, DHCP server, and the bare metal server.

[0101] The address pool query unit is used to parse the second DHCP request based on the DHCP server, obtain the target gateway address, and query the database to see if there is an address pool corresponding to the target gateway address.

[0102] The unit for obtaining the IP address to be used is used to obtain the IP address to be used from the address pool when the address pool corresponding to the target gateway address exists.

[0103] Furthermore, after the submodule for obtaining the IP address to be used, it also includes:

[0104] The configuration file acquisition unit is used to acquire the configuration file when the database does not contain an address pool corresponding to the target gateway address;

[0105] The partition length acquisition unit is used to acquire the total classless inter-domain route (CIDR) and the partition length of the address segment corresponding to the target deployment network based on the configuration file.

[0106] The address pool acquisition unit is used to obtain the address pool corresponding to the target gateway address based on the total CIDR and the partition length, so as to obtain the IP address to be used from the address pool.

[0107] Furthermore, the address pool acquisition unit includes:

[0108] A sub-unit is used to divide the total CIDR into at least one sub-address segment based on the division length;

[0109] The address pool determination unit is used to select the last sub-address segment among at least one of the sub-address segments as the address pool corresponding to the target gateway address, and to store the correspondence between the target gateway address and the last sub-address segment among the sub-address segments in the database.
