Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
In order that those skilled in the art will better understand the disclosure, reference will now be made in detail to the embodiments of the disclosure as illustrated in the accompanying drawings.
Next, a method for allocating an IP address based on multiple architectures according to an embodiment of the present invention will be described in detail. Fig. 1 is a flowchart of a method for allocating an IP address based on multiple architectures according to an embodiment of the present invention, where the method includes:
s101: and when the reserved IP address is obtained, setting a corresponding network and a subnet network for the reserved IP address.
In the embodiment of the invention, a certain IP address or IP address field can be appointed as a reserved IP address according to the requirement of a user.
To ensure availability of the reserved IP address, it is necessary to ensure that the reserved IP address has its corresponding network and subnet network. Therefore, in practical application, whether the acquired reserved IP address belongs to the existing subnet section can be judged. When the reserved IP address does not belong to the existing subnet section, a network of the reserved IP address and a subnet network need to be created. The subnet section of the subnet network comprises a reserved IP address.
When a network is created, attribute information required by the network, such as a network type, a management state, and an associated physical network card device, needs to be set. After the creation of the network is completed, a subnet network to which the IP address needs to be reserved and attribute information of the subnet, such as information of a subnet segment, a gateway, an address pool, etc., may be created under the created network view.
S102: and binding the reserved IP address with the reserved virtual port, and setting the port state of the virtual port as unavailable.
In the embodiment of the present invention, in order to manage the reserved IP address, a virtual port (Vport) may be reserved, and the reserved IP address is bound to the reserved virtual port.
To ensure that the reserved IP address is not called by other application services, the port state of the virtual port may be set to unavailable. In a specific implementation, relevant information such as the management state of the virtual port and the port security may be set to false.
S103: and when a high-availability service configuration instruction of the virtual cloud host is received, the target reserved IP address bound by the virtual port is used as the high-availability IP address of the virtual cloud host.
In practical application, a virtual cloud host can be established in a created subnet network, and when a high-availability service configuration instruction of the virtual cloud host is received, a reserved IP address matched with the subnet network to which the virtual cloud host belongs can be selected from the reserved IP addresses to serve as the high-availability IP address of the virtual cloud host.
In order to facilitate distinguishing from other reserved IP addresses, in the embodiment of the present invention, a reserved IP address that matches with a subnet network to which the virtual cloud host belongs may be referred to as a target reserved IP address.
S104: and generating a floating IP address corresponding to the high available IP address according to a preset access rule so as to facilitate a user to call the high available service of the virtual cloud host according to the floating IP address.
For a user, the high available IP address of the virtual cloud host cannot be known, so that the user can call the high available service of the virtual cloud host, a floating IP address for the user to use can be generated, and the floating IP address is bound with the high available IP address of the virtual cloud host, so that the user can access the high available virtual cloud host through the floating IP address.
An access rule refers to a rule on which a floating IP address is generated. The access rule may be set according to the address generation manner in the prior art, and is not limited herein.
According to the technical scheme, when the reserved IP address is obtained, in order to ensure the availability of the reserved IP address, a corresponding network and a subnet network need to be set for the reserved IP address; the subnet section of the subnet network comprises a reserved IP address. And binding the reserved IP address with the reserved virtual port, and setting the port state of the virtual port as unavailable. By setting the state of the virtual port to be unavailable, the condition that the reserved IP address is randomly called by other services can be effectively avoided. When a high-availability service configuration instruction of the virtual cloud host is received, the target reserved IP address bound by the virtual port is used as the high-availability IP address of the virtual cloud host; the target reserved IP address is a reserved IP address matched with the subnet network to which the virtual cloud host belongs. In order to enable a user to call a high-availability service of a virtual cloud host, a floating IP address corresponding to a high-availability IP address needs to be generated according to a preset access rule. The floating IP address refers to an address presented to a user, and the user can call the high-availability service of the virtual cloud host according to the floating IP address. In the technical scheme, the high-availability IP addresses required to be used for the virtual cloud host are reserved in advance, and unified management of all the reserved IP addresses is realized through one reserved virtual port, so that resource waste of the IP addresses and the port addresses is reduced, and the management of the high-availability IP addresses is simpler and more efficient.
In the embodiment of the present invention, in order to further verify whether the reservation of the reserved IP address is successful, before the target reserved IP address bound to the virtual port is used as the high available IP address of the virtual cloud host, when a high available service configuration instruction of the virtual cloud host is received, it may be determined whether the IP address allocated when the virtual cloud host is created coincides with the reserved IP address.
The reserved IP address can only be called by highly available services, other services cannot call the reserved IP address. When the allocated IP address does not coincide with the reserved IP address when the virtual cloud host is created, a step of using the target reserved IP address bound by the virtual port as a high available IP address of the virtual cloud host may be performed. When the allocated IP address is overlapped with the reserved IP address when the virtual cloud host is created, the reserved IP address is called by a service other than the high-availability service, and prompt information of high-availability failure of the reserved IP address can be displayed at the moment.
By comparing the IP address allocated when the virtual cloud host is created with the reserved IP address, whether the reserved IP address is only used for high-availability service can be effectively checked. By displaying the prompt message of the high availability failure of the reserved IP address, the manager can conveniently find the condition that the reserved IP address is illegally called in time, so that the service condition of the reserved IP address can be limited in time.
In the embodiment of the present invention, the high availability of the reserved IP address means that one reserved IP address can be bound to a plurality of virtual cloud hosts. In order to verify whether the reserved IP address meets high availability, after a floating IP address corresponding to the high availability IP address is generated according to a preset access rule, whether the virtual cloud host bound by the high availability IP address can be smoothly accessed according to the floating IP address can be judged.
When the virtual cloud host bound by the high available IP address can be smoothly accessed according to the floating IP address, the fact that the virtual cloud host bound by the high available IP address is indicated, at the moment, any one virtual cloud host bound by the high available IP address can be deleted, and then whether the virtual cloud host bound by the high available IP address can be smoothly accessed according to the floating IP address after one virtual cloud host is deleted is judged.
When the virtual cloud host bound by the high available IP address cannot be smoothly accessed according to the floating IP address, it is indicated that the binding between the high available IP address and the virtual cloud host fails, and the high available IP address does not meet the high availability.
When the virtual cloud host bound by the high available IP address cannot be smoothly accessed according to the floating IP address after one virtual cloud host is deleted, the high available IP address is only bound with one virtual cloud host, and the requirement of high availability is not met.
Therefore, when the virtual cloud host bound by the high available IP address cannot be accessed smoothly according to the floating IP address or when the virtual cloud host bound by the high available IP address cannot be accessed smoothly according to the floating IP address after one virtual cloud host is deleted, the alarm information that the high available IP address is invalid is displayed.
By displaying the alarm information of the high available IP address failure, the management personnel can timely know the condition that the high available IP address is not successfully bound to the virtual cloud host or only one virtual cloud host is bound, so that the management personnel can conveniently bind more virtual cloud hosts to the high available IP address, and the requirement of high availability is met.
The reserved IP address usually comprises a plurality of IP addresses, in practical application, the number of the reserved IP addresses can be dynamically adjusted, a new IP address can be added to serve as the reserved IP address, the reserved IP address can also be released, and the released reserved IP address can be called by other services.
In the specific implementation, after a floating IP address corresponding to a high available IP address is generated according to a preset access rule, when an available IP address used for virtual cloud host creation does not exist, whether an idle IP address exists in a reserved IP address or not can be judged; and when the idle IP address exists in the reserved IP address, releasing the idle IP address, and creating the virtual cloud host according to the released idle IP address. Wherein the free IP address refers to a reserved IP address that is not used.
By dynamically adjusting the number of the reserved IP addresses, different service requirements can be better met, and the service performance of the cloud platform is improved.
