Embodiment 1

[0045] An embodiment of the present invention provides a method for configuring an IP address. The execution subject of the method may be a server, that is, a physical node in a cloud computing system, or it may be understood as a physical server or a virtual machine, such as figure 1 As shown, the method includes:

[0046] Step 101, the server sends a DHCP request message to a Dynamic host configuration protocol (DHCP) server, where the DHCP request message is used to request an IP address;

[0047]In this embodiment, the server includes multiple network interface cards. When the server is started, the multiple network interface cards in the server will send DHCP messages to the DHCP server in order to obtain an Internet Protocol (Internet Protocol, IP) address for communication. DHCP is a LAN network protocol that uses the User Datagram Protocol (UDP) protocol to automatically assign IP addresses to internal networks or network service providers. UDP is a connectionless tra...

Embodiment 2

[0059] An embodiment of the present invention provides a server, which can also be understood as a physical server or a virtual server, such as Figure 2a As shown, including: sending unit 201, receiving unit 202

[0060] A sending unit 201, configured to send a DHCP request message to a Dynamic Host Configuration Protocol DHCP server, where the DHCP request message is used to request an IP address;

[0061] The receiving unit 202 is configured to receive the IP address and the attribute identifier of the IP address sent by the DHCP server; wherein the attribute identifier is used to identify that the IP address is a fixed IP address or a temporary IP address.

[0062] In this embodiment, the server includes multiple network interface cards. When the server is started, the multiple network interface cards in the server will send DHCP messages to the DHCP server in order to obtain an Internet Protocol (Internet Protocol, IP) address for communication. DHCP is a LAN network pro...

Embodiment 3

[0073] The invention provides a dynamic host configuration protocol DHCP server, such as image 3 As shown, it includes a receiving unit 301 and a sending unit 302; wherein, the receiving unit 301 is used as a receiving unit for receiving a DHCP request message sent by a server, and the DHCP request message is used for requesting to obtain an IP address;

[0074] The sending unit 302 is configured to send the IP address and the attribute identifier of the IP address to the server; wherein the attribute identifier is used to identify that the IP address is a fixed IP address or a temporary IP address. Wherein, the attribute identifier is used to identify that the IP address is a fixed IP address or a temporary IP address, specifically including:

[0075] When the attribute identifier includes the server information, the IP address is a fixed IP address; when the attribute identifier does not include the server information, the IP address is a temporary IP address; wherein, the ...

Abstract

The invention discloses an IP address configuration method, device and system, relating to the field of computer information technology, which can save temporary IP addresses, improve node loading efficiency, and ensure successful communication by releasing unused temporary IP addresses in time. In the embodiment of the present invention, the DHCP request message is sent to the DHCP server, and the DHCP message is used to request an IP address; the IP address and the attribute identification of the IP address sent by the DHCP server are received, and the IP attribute identification is used for the IP address. The address is a fixed IP address or a temporary IP address; the type of the IP address identified according to the attribute identifier is a temporary IP address, and the temporary IP address is released. The embodiment of the present invention is applicable to the configuration of the IP address during the loading process of the network interface card in the server.

Description

technical field [0001] The invention relates to the field of computer information technology, in particular to a method, device and system for configuring an Internet protocol IP address. Background technique [0002] In a cloud computing system, a large number of servers need to be deployed, for example, sometimes thousands of servers need to be deployed, wherein the server deployment includes installing operating systems and business software on nodes. When loading the server, the server may be loaded through different network interface cards according to different functions of the server. [0003] For example, the server includes n network interface cards, where n is greater than or equal to 1, and each network interface card supports loading. After the server 1 is started, all network interface cards started by the server 1 need to be assigned Internet Protocol IP addresses. The Dynamic host configuration protocol (DHCP) server assigns IP addresses to different network...
