Description
Technical Field
The present invention relates to the field of cloud platforms, and in particular, to a method, system, device, and storage medium for high availability of floating internet protocol addresses.
Background
The development of cloud computing is based on the new brilliance, the industrialization development of various industries is vigorous, and various fields such as government affairs, medical treatment, education and the like obtain very deep benefits from the brilliance, so that cloud is gradually a trend. Cloud computing is classified into a number of categories, where IaaS (Infrastructure as a Service ) refers to providing IT (Information Technology, information technology) infrastructure as a service externally through a network, in which service model users do not build a data center by themselves, but use infrastructure services including servers, storage and networks, etc. in a leased manner, iaaS has a similarity to traditional host hosting, but IaaS has a strong advantage in terms of flexibility, extensibility and cost of services, virtualization often serves as a basis for cloud computing, and virtualization separates resources and services from physical infrastructure delivery environments, by which multiple virtual systems can be created within a single physical system, and virtualized driving factors come from the merging of servers, which can provide an organization with efficiency and potential cost savings.
In the cloud platform, many users can achieve the purpose of providing various services by creating a cloud host and deploying a service system in the cloud host, which is generally the conventional operation of cloud on a service, and the process can depend on various cloud resources including computing, storage and networks in the cloud platform, and all organizations are closely cooperated to provide a guarantee for the services. In terms of network, the service can achieve the effect of being accessible by the external network, and some network cloud resources are required to be configured in the cloud platform to open the communication between the cloud host in the cloud and the external internet, so that the open network link becomes a channel for providing the service for the system and enabling the user to participate in interaction.
Stability and reliability are usually the criteria for measuring the quality of a system, and are often not problematic in any link, especially for service systems with higher requirements. However, the network environment is not invariable, and cloud resources configured in the cloud environment are all round, but if one of them fails, the whole link is definitely paralyzed, if no effective evading measures are taken, the problem cannot be effectively processed due to the fault development, so that service interruption or more serious hidden danger is caused, and very bad influence is inevitably generated, so that it is extremely valuable how to actively defend in advance, and how to effectively process the problem in time.
In a cloud environment based on an OpenStack platform, a cloud host is widely applied as a computing resource, and a user deploys a service system in a cloud and configures various service strategies in the cloud by taking the cloud host as a center. It is not enough that the cloud host provides the service only by the one independent individual, the cloud host provides the cloud computing service, the user obtains the service from the cloud host, and a stable network link is needed in the process to enable the user to interact with the cloud computing resource. However, the network resources in the cloud can not always function stably from the start of creation, and the health state of the network resources cannot be permanently guaranteed, although the risk is controllable, the possibility of unexpected situations can be effectively low, but various problems such as functional damage of a virtual network card, network failure and the like cannot be absolutely avoided, and if a mode can be found to realize automatic recovery of network communication, the reliability of the whole system is greatly increased.

It should be noted that, in the embodiments of the present invention, all the expressions "first" and "second" are used to distinguish two entities with the same name but different entities or different parameters, and it is noted that the "first" and "second" are only used for convenience of expression, and should not be construed as limiting the embodiments of the present invention, and the following embodiments are not described one by one.
In a first aspect of the embodiments of the present invention, an embodiment of a method for floating internet protocol address high availability is presented. Fig. 1 is a schematic diagram of an embodiment of a method for floating internet protocol address high availability provided by the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:
s1, responding to network failure, calling an interface of qga to delete the existing static route, unbinding a floating internet protocol address and a service network card, selecting a new available service network, and creating a new service network card on a cloud host;
s2, setting an external network to which the floating IP address belongs as an external gateway of a virtual router, and designating a fixed IP address as a gateway address;
s3, binding a virtual network to which the new service network card on the cloud host belongs to the virtual router, and designating a fixed Internet protocol address as a virtual interface address; and
s4, calling an interface of qga to create a new static route in the virtual machine according to the virtual interface address, and monitoring network connectivity at fixed time.
OpenStack: a cloud computing management tool, which is used to manage the resources (cloud hosts, storage, networks, etc.) of the IaaS cloud. qga: a common application program running inside a virtual machine (an executable file name defaults to QEMU-ga, a service name defaults to QEMU-gust-agent) aims to realize a way of interaction between a host machine and the virtual machine, and the way is independent of a network and depends on a virtual-service (default preferred way) or an isa-service, while the QEMU provides a channel for simulation and data exchange of a serial device, and finally, a serial device (inside the virtual machine) and an unix socket file (on the host machine) are presented.
The invention aims to solve the problem that when a systematic network is not feasible, how to ensure high availability characteristics by supporting an automation strategy of built-in scripts, needing no manual intervention of operation and maintenance personnel and automatically recovering network connectivity.
The focus of the embodiments of the present invention is how to solve the problem of network interruption that has occurred, that is, there must be some cloud host deployed and each configuration already in effect before this time, the service has been operated without error, and then a network failure occurs, which is the moment when the embodiments of the present invention need to function. Whether the cloud host is initialized and deployed or configured, or a series of operations to be performed by the automation strategy in the embodiment of the invention, all around are virtual cloud resources on the cloud platform, and users deploy the cloud host and provide services, so that network configuration of the cloud host is needed to be completed first.
Planning and deploying an external network which is open to a public network, a standby service network used in a plurality of clouds and a plurality of virtual routers in a cloud platform; an unused floating IP (Internet Protocol ) is assigned with the selected external network designation, which is a private service address for future use in providing services. And selecting a certain service network and creating a service network card on the cloud host.
Setting an external network to which the floating IP belongs as an external gateway of a certain virtual router, and designating a certain fixed IP as a gateway address; binding the virtual network to which the cloud host network card belongs to the same virtual router, and designating the fixed internet protocol address as a virtual interface address. Thus, the virtual router communicates with the external network and the service network, and at this time, binds the floating IP to the service network card on the virtual machine.
Calling the interface of qga, creating a static route in the virtual machine, so that a network message can be transmitted from the service network card in the transmission process, forwarded by the virtual router and then enters the public network through the floating IP.
In some implementations, the interface of call qga creating a new static route within the virtual machine from the virtual interface address includes: setting the destination address of the static route to a network segment comprising all addresses.
In some implementations, the interface of call qga creating a new static route within the virtual machine from the virtual interface address includes: setting the next-hop address of the static route as a virtual interface address appointed when the virtual network to which the service network card belongs is bound to a virtual router.
In some implementations, the interface of call qga creating a new static route within the virtual machine from the virtual interface address includes: and setting the network card through which the static route passes as a service network card bound by the floating internet protocol address.
The static route comprises the following components: the destination address is a network segment comprising all addresses; the next-hop address is a virtual interface address appointed when the virtual network to which the service network card belongs is bound to a virtual router; the network card passed through is the virtual machine service network card bound by the floating IP.
And in response to network failure, calling an interface of qga to delete the existing static route, unbinding the floating internet protocol address and the service network card, selecting a new available service network, and creating a new service network card on the cloud host. Periodically monitoring network connectivity, and when the network connectivity is not enabled, calling an interface of qga to delete the static route created by qga in the cloud host; the floating IP is unbound with the virtual network card of the original cloud host; and automatically selecting another available service network, and creating a new service network card on the cloud host.
Then the steps are executed again, namely: setting an external network to which the floating internet protocol address belongs as an external gateway of a virtual router, and designating a fixed internet protocol address as a gateway address; binding a virtual network to which the new service network card on the cloud host belongs to the virtual router, and designating a fixed internet protocol address as a virtual interface address; and invoking an interface of qga to create a new static route within the virtual machine based on the virtual interface address and to monitor network connectivity at a timed time.
The edited script is used for directionally updating the system configuration or the network guidance of the service system through calling qga interfaces, and other customized configuration changes which are changed through the script are carried out; and recovering the automatically created service network card which is not used any more, and relieving the occupation of resources.
And an external network, an intra-cloud service network and a virtual router are planned in the cloud platform and are all required by the service. The virtual machine network card binding floating IP is a basic operation in the cloud platform, the embodiment of the invention does not describe in detail aiming at independent binding procedures, the embodiment of the invention focuses on adopting automatic service control, ensuring that the network is automatically switched under the condition of zero intervention of a user, integrating a monitoring technology for judging the network connectivity, integrating a proxy mechanism for updating the new guidance of the network message in the cloud host, supporting the implantation and execution of a system custom script, ensuring the network communication after the floating IP regains binding, and having extremely high availability characteristic.
It should be noted that, if the static route is not redefined inside the cloud host, the network packet cannot be directed from the cloud host to the public network, i.e., the network connectivity is lost, without talking about the high availability of the floating IP. By writing customized server instructions in custom embedded scripts, a business system running in an operating system can automatically adapt to new changes in the whole process, and each time the automatic switching of network abnormality is monitored, the scripts are loaded and then the cloud host is triggered to execute through qga. The script is independently compiled for a certain cloud host by an operation and maintenance user according to specific needs, when the floating IP is manually bound to the cloud host for the first time, whether the embodiment of the invention achieves the highly available effect or not can be selected, if the floating IP is selected, the script is bound together in the process, and the bound script has the possibility of being used at any time. The whole set of processes of the embodiment of the invention are under the automatic operation process, and are mutually buckled, so that manual intervention of a user is not required.
The embodiment of the invention can flexibly release the binding relation between the allocated floating IP and the fault network card, reestablish a new network card and bind the floating IP with the new network card, simultaneously can automatically change the static route in the cloud host so that the network message can switch the transmission guide to avoid secondary non-communication, and can also allow a user to obtain the automatic execution of the adaptive necessary operation related to the change of the network environment in a self-defined script mode.
It should be noted that, the steps in the embodiments of the above method for floating ip address high availability may be intersected, replaced, added and subtracted, so that these methods for reasonably permutation and combination transformation to floating ip address high availability shall also fall within the protection scope of the present invention, and shall not limit the protection scope of the present invention to the embodiments.
