Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to an IP address allocation method, binding method, device, equipment, and medium. Background Technology

[0002] In the field of computer technology, the most basic step in using a bare-metal server is to complete the operating system installation and assign IP addresses to achieve device reachability. A Preboot Execute Environment (PXE) can be used for unattended system installation scenarios. After system installation is complete, PXE's built-in Dynamic Host Configuration Protocol (DHCP) service assigns a dynamic IP address to each client, thus achieving device reachability.

[0003] Current technical solutions use DHCP to dynamically allocate IP addresses to the operating system. This automatic allocation method is done in batches and automatically, and cannot obtain an accurate correspondence between servers and IP addresses. It is necessary to manually log in to the operating system of a specified server and modify it to a specified IP address in order to achieve a one-to-one correspondence between servers and IP addresses.

[0045] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0046] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0047] See Figure 1 The embodiments of this application provide an IP address allocation method, which is applied to an IP address allocation device, and the specific steps include: step 101, step 102 and step 103.

[0048] Step 101: Assign an IP address to each device based on its location information and / or its switch connection information;

[0049] The device in this embodiment can also be called a PXE client, and the IP address can be a static IP address.

[0050] Step 102: Based on the first identification information of each device in the out-of-band network and the IP address of each device, generate the first correspondence information between the first identification information of the device in the out-of-band network and the IP address;

[0051] In this embodiment, the identification information includes at least one of the following: device serial number, motherboard serial number, and MAC address.

[0052] If the identification information is a MAC address, then in step 102, a first correspondence information between the MAC address and IP address of the target device is generated. This first correspondence information may be a first MAC-IP list.

[0053] Step 103: Send the first correspondence information to the target device. The first correspondence information is used to determine the static IP address of the target device by combining the identification information of the target device in the in-band network, so as to obtain the second correspondence between the target device and the static IP address.

[0054] That is, the IP address allocation device sends the first correspondence (e.g., the first MAC-IP list) to the target device, the target device's operating system determines the target device's static IP address based on the first correspondence and the target device's identification information in the in-band network, and the target device's operating system binds the target device to the static IP address.

[0055] In this embodiment, the binding of the target device to a static IP address is completed by using the relevant information of the target device in the in-band network and out-of-band network, which can achieve a one-to-one correspondence between the device and the IP address.

[0056] In one embodiment of this application, sending the first correspondence to the target device includes:

[0057] Obtain the dynamic IP address assigned to the target device by the DHCP server;

[0058] The first correspondence is sent to the target device via the dynamic IP address.

[0059] The aforementioned dynamic IP address can also be called a temporary IP address.

[0060] In one embodiment of this application, obtaining the dynamic IP address assigned to the target device by the DHCP server includes:

[0061] Obtain the first IP address of the target device when the operating system is installed and the third identification information of the device corresponding to the first IP address;

[0062] Based on the first correspondence information, a first identification information related to the third identification information is determined as the unique identification information of the target device;

[0063] Obtain the second IP address in the in-band network assigned by the DHCP server to the operating system of each device, and the fourth identification information of the device corresponding to the second IP address;

[0064] The unique identifier information is compared with the fourth identifier information, and the target IP address is determined to be the dynamic IP address assigned to the target device by the DHCP server. The target IP address is the second IP address corresponding to the fourth identifier information related to the unique identifier information.

[0065] For example, obtain the first IP address of the target device when the operating system is installed and the MAC address corresponding to the first IP address, generate a second MAC-IP list, compare the second MAC-IP list with the first MAC-IP list, and use a MAC address of the target device (first identification information) as the unique identification information of the target device.

[0066] It should be noted that the first IP address and the second IP address can be the same, or they can be different.

[0067] Optionally, after the operating system installation on one or more devices is completed, the step of obtaining the second IP address in the in-band network assigned by the DHCP server to the operating system of each device and the fourth identification information of the device corresponding to the second IP address is executed. It is understood that this embodiment performs initial IP address configuration after the operating system is installed.

[0068] In one embodiment of this application, prior to step 102, the method further includes:

[0069] The device's first identification information in the out-of-band network is obtained through the out-of-band management interface. The first identification information includes at least one of the following: device serial number, motherboard serial number, and MAC address.

[0070] For example, the number of devices can be n. The MAC address of the network card of device 1 can include MAC_1-1, MAC_1-2, ..., MAC_1-m, and the MAC address of the network card of device n can include MAC_n-1, MAC_n-2, ..., MAC_n-m, where m is the number of network cards.

[0071] In this embodiment, an IP address is assigned to each device based on its location information and / or its switch connection information; a first correspondence between the first identification information and the IP address of each device in the out-of-band network is generated based on the first identification information of each device in the out-of-band network and the IP address of each device; the first correspondence is sent to the target device, and the first correspondence is used to determine the static IP address of the target device by combining it with the second identification information of the target device in the in-band network, so as to obtain the second correspondence between the target device and the static IP address, thereby binding the target device and the static IP address.

[0072] See Figure 2 The embodiments of this application provide an IP address binding method applied to a target device, the specific steps of which include:

[0073] Step 201: Obtain the first correspondence information between the identification information and IP address of at least some devices in the out-of-band network, wherein the IP address is related to the device's location information and / or the device's switch connection information;

[0074] Step 202: Compare the first correspondence information with the second identification information of the target device in the in-band network, and determine the IP address corresponding to the first identification information related to the second identification information as the static IP address of the target device;

[0075] Step 203: Establish a second correspondence between the target device and the static IP address.

[0076] Optionally, the target device's operating system uses scripts or commands to perform static IP address binding based on the first correspondence information and the target device's second identification information in the in-band network.

[0077] In one embodiment of this application, obtaining a first correspondence between the identification information and IP address of at least some devices in an out-of-band network includes:

[0078] The PXE server's POST process is used to obtain at least some of the devices' out-of-band network identification information and the first correspondence between their IP addresses.

[0079] or,

[0080] The device receives a first correspondence information between the identification information of at least a portion of the devices in the out-of-band network and the IP address sent by the IP address allocation device via a dynamic IP address, wherein the dynamic IP address is allocated by a DHCP server.

[0081] In this embodiment, a first correspondence between first identification information and IP address of at least some devices in an out-of-band network is obtained, wherein the IP address is related to the device's location information and / or the device's switch connection information; the first correspondence is compared with the second identification information of the target device in an in-band network, and the IP address corresponding to the first identification information related to the second identification information is determined as the static IP address of the target device; a second correspondence is established between the target device and the static IP address to achieve binding between the target device and the static IP address.

[0082] See Figure 3 This embodiment provides an IP address allocation and binding process, with the following specific steps:

[0083] Step 301: Obtain the first identification information of the device in the out-of-band network;

[0084] For example, the first identification information of a device in an external network can be obtained through an out-of-band management interface. The list of first identification information includes at least one of the following: device serial number, motherboard serial number, and MAC address.

[0085] For example, the number of devices can be n. The MAC address of the network card of device 1 can include MAC_1-1, MAC_1-2, ..., MAC_1-m, and the MAC address of the network card of device n can include MAC_n-1, MAC_n-2, ..., MAC_n-m, where m is the number of network cards.

[0086] Step 302: Assign an IP address to each device based on at least one of the device's location information and the device's switch connection information, and generate a first correspondence between the device's first identification information and the IP address based on the device's identification information list and the IP address;

[0087] It is understandable that the first correspondence information records the correspondence between the first identifier information and the IP address.

[0088] For example, the network configuration of device 1 is performed based on at least one of the first identification information list of device 1, the location information of device 1, and the switch connection information of device 1.

[0089] Step 303: Install the operating system on n devices via the PXE server;

[0090] Step 304: Obtain the first IP address (temporary IP1) of the target device and the third identification information of the device corresponding to the first IP address when installing the operating system;

[0091] For example, device 1 can send a request to the PXE server through a certain port, and the request can carry the device's third identification information (such as a second MAC address).

[0092] Step 305: Compare the third identification information with the first correspondence information, and determine a first identification information related to the third identification information as the unique identification information of the target device;

[0093] For example, a MAC address of the target device can be used as the unique identifier of the target device.

[0094] Step 306: Determine if the operating system installation is complete;

[0095] Step 307: After the operating system installation is complete, obtain the second IP address (temporary IP2) and the corresponding fourth identification information (e.g., the first MAC address) in the in-band network assigned by the DHCP server to the operating system of each device.

[0096] The second IP address mentioned above can be the same as the first IP address, or it can be different.

[0097] It is understandable that PXE servers and DHCP servers can be configured together, meaning they can be on the same server, or they can be configured independently.

[0098] For example, a device can send a request to a DHCP server, which can include the device's first MAC address.

[0099] Step 308: Compare the unique identifier information of the target device with the second IP address and the fourth identifier information of the device corresponding to the second IP address, and determine the target IP address as the dynamic IP address assigned to the target device by the DHCP server. The target IP address is the second IP address corresponding to the fourth identifier information related to the unique identifier information.

[0100] For example, the target device's dynamic IP address (or temporary IP address) is the second IP address.

[0101] Step 309: Send the first mapping relationship to the target device based on the target device's dynamic IP address;

[0102] Step 310: Obtain the second identification information of the target device in the in-band network through the operating system;

[0103] Step 311: Compare the first correspondence information with the second identification information of the target device in the in-band network, determine the IP address corresponding to the first identification information related to the second identification information as the static IP address of the target device, and establish the second correspondence information between the target device and the static IP address.

[0104] For example, the target device's operating system obtains the target device's second identification information in the in-band network, and uses a script or command to complete the static IP binding based on the target device's first correspondence information.

[0105] See Figure 4 This application provides a network topology diagram, which includes: an IP address allocation device, a control module, and a PXE server. The IP address allocation device is used to allocate an IP address to each device based on the device's location information and / or the device's switch connection information; generate a first correspondence between the first identification information of each device in the out-of-band network and the IP address of each device based on the first identification information of each device in the out-of-band network and the IP address of each device; send the first correspondence information to a target device, wherein the first correspondence information is used to determine the static IP address of the target device in combination with the identification information of the target device in the in-band network, so as to obtain a second correspondence between the target device and the static IP address; the control module is responsible for configuration, and the control module and the IP address allocation device can be set together or set separately; the PXE server and / or DHCP server are responsible for initial DHCP allocation, providing system image files, etc.

[0109] The sending module 503 is used to send the first correspondence information to the target device.
