Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
According to the switching method, when the situation that the destination address corresponding to the destination domain name and in use is abnormal is monitored, the access address is switched according to a preset switching strategy.
An embodiment of the present application first provides a handover method, as shown in fig. 1, including:
step 101: acquiring a destination domain name to be monitored;
step 102: acquiring a destination address which is corresponding to a destination domain name and needs to be monitored, wherein the destination address is an address of a current access destination domain name;
step 103: judging whether the destination address is abnormal or not according to the access condition of the destination address;
step 104: and under the condition that the destination address is judged to be abnormal, switching the access address of the destination domain name from the destination address to another address in all addresses corresponding to the destination domain name according to a preset switching strategy.
In this embodiment, the destination domain name to be monitored may be one domain name or multiple domain names. These domain names may be customized to allow address switching.
The destination address to be monitored corresponding to the destination domain name may be an address entered by the user when accessing the destination domain name. May be one of a plurality of addresses corresponding to the destination domain name.
The access status of the destination address may refer to a normal or abnormal status of all users accessing the destination address. For example, the number of consecutive unsuccessful visits to the destination domain reaches a set value.
The preset switching policy may be a selection policy for another address of a destination domain name for switching with a destination. In the distributed object storage, the problems of large user access flow and high cost of flow accounting for the total cost exist, and the domain name entry provided by the service binds the addresses of a plurality of machine rooms and operators in order to improve the service availability. Different switch granularities are provided for different users. From historical experience, when the destination address fails, the probability of address failure of the same machine room is high, and secondary failure may occur when the destination address is switched to the local machine room. Therefore, when the user is a core user, if the destination address fails, another address of the different-place machine room under the same domain name is preferentially selected to execute the switching operation, so that the switching times can be reduced, and the availability of the switched address is improved. When the user is a common user, if the destination address fails, another address under the same domain name of the local machine room is selected to execute switching, so that the flow cost can be reduced.
The destination address can be a main address preset by a destination domain name; the other of all the addresses corresponding to the destination domain name may be a preset backup address of the destination domain name. After the access address of the destination domain name is switched from the destination address to another address of all addresses corresponding to the destination domain name, the access address corresponding to the destination domain name may be switched from the destination address a to another address B, and then when the user accesses the destination domain name, the user accesses through another address B corresponding to the destination domain name.
In the embodiment of the application, under the condition that the abnormality of the destination address of the destination domain name is monitored, the access address of the destination domain name is switched to another one of the addresses corresponding to the destination domain name from the destination address according to a preset switching strategy, so that a countermeasure can be quickly taken against the condition that a user entry in a system is abnormal, the condition that the user entry cannot be accessed due to the abnormal address is avoided, the flow of the user is lost, and the success rate of the user access and the user experience are improved.
The destination address may be a VIP corresponding to the destination domain name.
In another embodiment, the determining whether the destination address is abnormal according to the access status of the destination address includes:
and when the abnormal rate of the target client accessing the target address is a first set value, judging that the target address is abnormal.
In this embodiment, the target client accessing the destination address may be all clients accessing the destination address, or may be a selected part of all clients accessing the destination address. The exception rate of the target client accessing the destination address may be a ratio of the number of exceptions to the total number of accesses during the process of accessing the destination address by the target client.
Under a loose monitoring strategy, whether the destination address is abnormal can be judged only according to the abnormal rate of the destination address accessed by the target client, and the number of times of failed access of the user can be reduced to a greater extent.
In another embodiment, the determining whether the destination address is abnormal according to the access status of the destination address includes:
and when the abnormal rate of the target client accessing the destination address is a first set value and the ping instruction of the times of continuously executing a second set value on the destination address fails, judging that the destination address is abnormal.
In this embodiment, under a strict monitoring policy, in the case that the destination address is abnormal, a ping instruction is executed for the destination address, and if the number of times of continuous ping failures reaches a set value, it is determined that the destination address is abnormal, and the number of addresses in the destination domain name can be saved by adopting the strict monitoring policy.
In another embodiment, switching the access address of the destination domain name from the destination address to another address of all addresses corresponding to the destination domain name according to a preset switching policy includes:
under the condition that the preset switching strategy is a switching strategy for reducing switching time, switching the destination address into an address corresponding to the destination domain name in a different-place machine room;
and under the condition that the preset switching strategy is a switching strategy for reducing the flow cost, switching the destination address into an address corresponding to the destination domain name in the local machine room.
Because the requirements for address switching are different under different scenarios. For example, for an important core user, it is necessary to provide better product use experience for the core user as much as possible, and therefore, when performing address switching, it is necessary to shorten the address switching time as much as possible. When one destination address is abnormal, the probability that other addresses distributed in the machine room and the destination address are also abnormal is higher, so that the machine room is switched to a different-place machine room, the trial and error times of address access can be reduced, and the switching time is saved. Because the selection of the address of the different-place machine room for switching has larger flow consumption, the address of the same machine room can be preferentially selected for switching for the non-core user.
In this embodiment, different switching strategies can be formulated according to different user requirements, so as to meet the service requirements of different users.
In another embodiment, when it is determined that the destination address is abnormal, switching the access address of the destination domain name from the destination address to another address of all addresses corresponding to the destination domain name according to a preset switching policy, further includes:
and when the number of destination addresses which need to be switched simultaneously currently exceeds a set threshold value, refusing to execute the step of switching the access address of the destination domain name from the destination address to the other address in all addresses corresponding to the destination domain name.
In large-scale distributed object storage, user access flow is large, a plurality of addresses of a plurality of domain names which are hung with machine rooms and operators exist, when a single machine room with large outlet flow fails, if the plurality of domain names execute switching at the same time, the plurality of domain names can be switched to another machine room with small outlet flow at the same time, and further flow avalanche is caused, and other services of the machine room with small outlet flow are influenced. In this embodiment, a threshold is set, and when the number of destination addresses that need to be switched exceeds the set threshold, the execution of the switching is rejected. Meanwhile, when the machine rooms in different places are built in the previous period, the machine rooms with large outlet flow can be selected for the clusters with large user flow, so that switching tasks of more destination addresses can be received at the same time.
In this embodiment, when the traffic generated during switching is too large, the switching operation is not performed, so that a new problem caused by that the switching traffic is too large and exceeds the traffic that can be borne by the machine room in which another address of all addresses corresponding to the destination domain name is located is avoided. The destination address can be a VIP corresponding to the destination domain name, the health state of the VIP is monitored through the monitoring system, when the monitored VIP reaches an abnormal threshold value, a VIP abnormal alarm can be triggered, the VIP switching platform is manually logged in, and a proper VIP is selected to switch and stop damage.
In the embodiment of the application, an automatic switching Dry Run (trial Run) mode can be set, so that the operation and maintenance performance and the safety are improved. The Dry Run mode is used for simulating switching when the VIP automatic switching strategy is changed or just on line, when the main VIP fault is detected in the mode, a proper standby VIP is selected, the switching strategy is issued but the switching strategy does not actually take effect, and the aim is to test the effect of the switching strategy. And observing whether the switching strategy is in accordance with the expectation or not by simulating the process of automatic switching of the VIPs when the main VIP fails.
An embodiment of the present application further provides a switching device, as shown in fig. 2, including:
a domain name obtaining module 201, configured to obtain a destination domain name to be monitored;
an address obtaining module 202, configured to obtain a destination address to be monitored, where the destination address corresponds to a destination domain name, and the destination address is an address of a currently visited destination domain name;
the exception judging module 203 is used for judging whether the destination address is abnormal or not according to the access condition of the destination address;
and the switching execution module 204 is configured to switch the access address of the destination domain name from the destination address to another address of all addresses corresponding to the destination domain name according to a preset switching policy when it is determined that the destination address is abnormal.
In one embodiment, as shown in fig. 3, the abnormality determining module further includes:
a first determining unit 301, configured to determine that an abnormality occurs in the destination address when an abnormality rate of the destination client accessing the destination address is a first set value.
In one embodiment, as shown in fig. 4, the abnormality determining module further includes:
a second determination unit 401, configured to determine that the destination address is abnormal if the ping fails when the abnormality rate of the destination client accessing the destination address is a first set value and the number of times of continuously executing a second set value on the destination address.
In one embodiment, as shown in fig. 5, the handover performing module further includes:
a first executing unit 501, configured to switch a destination address to an address corresponding to a destination domain name in a different-place machine room when a preset switching policy is a switching policy that reduces switching time;
the second executing unit 502 is configured to, if the preset switching policy is a switching policy that reduces traffic cost, switch the destination address to an address corresponding to the destination domain name in the local computer room.
In one embodiment, in the case that it is determined that the destination address is abnormal, the handover performing module is further configured to:
and when the number of destination addresses which need to be switched simultaneously currently exceeds a set threshold value, refusing to execute the step of switching the access address of the destination domain name from the destination address to the other address in all addresses corresponding to the destination domain name.
The switching device provided by the embodiment of the application can accurately identify VIP abnormity when a VIP fault occurs, selects a proper standby VIP and quickly completes VIP automatic switching.
An example of the switching device provided in the present application, as shown in fig. 6, includes: a VIP loading module 601, a VIP monitoring module 602, a VIP switching module 603, wherein,
the VIP loading module 601: the module can acquire the available domain names of the full cluster, namely all the available domain names of one server side, through the operation and maintenance data center. And reading a domain name white list which can be automatically switched from the domain names available in the full cluster. The domain name white list capable of automatic switching can be a domain name allowing automatic address switching. The domain name white list capable of automatically switching the zones is customizable by a user, a plurality of domain names are provided by a data system, the switching function is only opened for a specific domain name, and the domain name without the switching function is not in the domain name white list capable of automatically switching. For example, the domain name under maintenance may not be set in the white list, the domain name for object storage may open automatic switching, and the domain name for offline storage may not open automatic switching. The domain names in the white list are the domain names to be monitored, namely the destination domain names. There may be many VIPs under a domain name in the domain name white list that can be automatically switched, and there are primary VIPs and backup VIPs of the domain name, and an incoming VIP can switch within the VIP range under the domain name when accessing the domain name. The VIP loading module 601 calls the VIP switching platform to acquire all VIPs of domain names that can be automatically switched by the current cluster. The domain names in the domain name white list capable of being automatically switched can be analyzed through a public network domain name analysis system, and the VIP under the domain names is obtained.
The VIP monitoring module 602: the module is responsible for VIP health state acquisition, namely judging whether the VIP is abnormal or not according to the VIP access condition. The VIP monitoring module 602 may determine whether the VIP is abnormal by setting a policy. For example, the setting policy may be a strict mode policy, and under the strict mode policy, when the VIP abnormality rates obtained by obtaining all the operator monitoring clients are set values (e.g., 100%), and the VIP that reaches the set value abnormality rate fails to perform ping continuously for a set number of times (e.g., 3 times), it is determined that the VIP is abnormal. The setting policy may also be a loose mode policy: and when the VIP abnormal rate acquired by the monitoring client of the same operator exceeds a threshold value, judging that the VIP is abnormal.
The VIP switching module 603: the module is responsible for selecting a proper standby VIP to call the VIP switching platform to complete the switching operation, and the switching strategy of the VIP switching module 603 can be set as required. For example, the switching policy may be a same-room priority policy, that is, a VIP in the same room is preferentially selected to switch. Under the same machine room strategy, when the destination address is the main VIP and the main VIP is abnormal, the VIP in the same machine room is preferentially selected to be switched among all available standby VIPs in the same operator, and the same machine room priority strategy can be used for a VIP forbidden scene. For another example, the switching policy may be a different place machine room priority policy, that is, the VIP of the different place machine room is preferentially selected for switching. Under the priority strategy of the different-place machine room, when the main VIP is abnormal, the VIP of the different-place machine room is preferentially selected from all available standby VIPs of the same operator, and the scenes of poor quality of machine room outlets and fault of the operator are mainly used.
In another example of the present application, as shown in fig. 7, the switching means includes a VIP monitoring platform 701, a VIP switching platform 702, and a VIP presentation platform 703. The VIP monitoring platform 701 obtains the global domain name corresponding to the server and the global VIP corresponding to the global domain name from the operation and maintenance data center, and loads the global VIP through the VIP loading module 704. The VIP switching platform 702 monitors the loaded VIP using the VIP monitoring platform 701, and for an abnormal VIP, switching is performed at the VIP switching platform 702. The VIP display platform 703 displays the domain name-bound primary VIP and the standby VIP.
