Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The power data disaster recovery method provided by the application can be applied to the application environment shown in fig. 1. Wherein the first server 102 communicates with the second server 104 over a network. The first server 102 and the second server 104 may be arranged in a distributed storage dual active architecture, and the second server 104 may normally receive a pending power service request sent from a user terminal and process the power service request. The first server 102 may obtain the pending power service request of the second server 104 when the failure information of the second server 104 is detected, and process the pending power service based on the same stored power data as the second server 104 and by using the same service logic as the second server 104, store the pending power data in the pending power service request to form stored power data. The first server 102 and the second server 104 may be implemented by independent servers or a server cluster composed of a plurality of servers.
In an embodiment, as shown in fig. 2, a power data disaster tolerance method is provided, which is described by taking the method as an example applied to the first server in fig. 1, and includes the following steps:
step S202, detecting the fault information of the second server, and acquiring a to-be-processed power service request of the second server; the pending power service request comprises pending power data; the first server stores the same stored power data and service processing logic as the second server; the stored power data and the service processing logic are obtained by performing data synchronization with the first server when the second server stores the power data to be processed in the power service request sent by the user terminal.
The user terminal can be a terminal held by a user needing to perform the power service, and the user can perform the corresponding power service through the user terminal; the second server may be a primary server and the first server may be a backup server. The second server 104 may receive the pending power service request from the user terminal under normal conditions, and process the pending power service request sent by the user terminal through the service processing logic of the second server 104 based on the stored power data in the second database of the second server 104. The first server 102 and the second server 104 may be disposed in the same distributed storage dual live architecture.
The first server 102 and the second server 104 may be communicatively connected, and may implement bidirectional synchronization of data and services, when the second server 104 fails, for example, when encountering a natural disaster or a human damage, the second server 104 may send failure information to the first server 102, and the first server 104 may detect the failure information of the second server 104 and perform disaster recovery processing by the first server 102. When the second server 104 fails, the first server 102 may obtain pending power service requests of the second server 104 that are being processed. Wherein, the pending power service request includes pending power data. Because a double-center synchronous mode is adopted between the first server 102 and the second server 104, data processing can be simultaneously performed between the main server and the standby server, and real-time increment is realized, so that the same stored electric power data and the same service processing logic as those of the second server 104 are stored in the first server 102. The stored power data represents power data formed by storing the obtained processed power data after the first server 102 or the second server 104 processes the power service to be processed, that is, the stored power data is power data stored in a database. The service processing logic may be processing logic for the pending power service request, for example, the pending power service may be a data write request, and the first server 102 and the second server 104 have the same storage principle for the pending power service request.
When the second server 104 finishes storing the to-be-processed power data, before returning a processing result to the user terminal, data synchronization may be initiated to the first server 102, and then the first server 102 and the second server 104 may synchronize the service processing logic and the stored power data, thereby ensuring data consistency and processing logic consistency between the first server 102 and the second server 104.
Step S204, the electric power service request to be processed is processed according to the service processing logic, and the electric power data to be processed is stored in a first database of the first server and serves as the stored electric power data.
The service processing logic of the first server 102 may be the same as the service processing logic of the second server 102, the first server 102 serves as a standby server, when the second server 102 fails, the to-be-processed power service request being processed by the second server 102 may be processed according to the same service processing logic as the second server 104, the to-be-processed power service request includes to-be-processed power data, the first server 102 processes the to-be-processed power data to obtain processed power data, the first server 102 may store the processed power data in the first database of the first server 102 as new stored power data, update of the database is achieved, processing of the to-be-processed power service of the user terminal is completed, disaster tolerance processing of the power data is achieved, and when the second server 104 serving as a main server fails, disaster tolerance processing of the power data may also be performed by the first server 102 And the non-inductive switching and the non-inductive processing of the power service are realized.
The various power data may be unstructured power data, and the processing of the power data disaster tolerance may be a data disaster tolerance method based on unstructured data, because the amount of unstructured data is large, and the storage of individual files is large, the first server 102 and the second server 104 may adopt a double-center synchronization mode, thereby ensuring disaster recovery capability, reducing data loss, and realizing real-time increment of power data. Through the double-center synchronization mode, data between the first server 102 and the second server 104 are not different, and the service system can be used after being switched, so that the risk of data loss is reduced, and the long-term stable operation of the service system is ensured.
In the power data disaster recovery method, when the second server is detected to be out of order, the to-be-processed power service request which is being processed by the second server is acquired. The first server stores stored power data and service processing logic which are the same as those of the second server, and the stored power data and the service processing logic are obtained by performing data synchronization with the first server when the second server stores the to-be-processed power data in the power service request. The first server processes the power service request to be processed according to the service processing logic, stores the power data to be processed into the first database as stored power data, and when the second server is detected to restore operation, the first server can also perform data synchronization with the second server to restore the data of the second server. Compared with the traditional backup disaster recovery mode based on the local disk, the scheme utilizes the first server which has the same stored power data and service processing logic as the second server to process the power service request which is processed by the second server when the second server fails, thereby realizing the non-inductive processing of the service and improving the backup efficiency of the power data disaster recovery.
In one embodiment, further comprising: receiving a multi-copy replication request sent by a second server; the multiple copy requests comprise processed power data obtained after the second server processes the power service request sent by the user terminal; acquiring processed power data in the multiple copy requests and storing the processed power data in a first database to obtain stored power data; sending storage completion information to a second server; the second server is used for receiving the storage completion information and returning the electric power service processing completion information to the user terminal.
In this embodiment, the second server 104 may serve as a main server to receive the power service request of the user terminal under a normal operation condition, and the second server 104 may obtain the processed power data after processing the power service request. The first server 102 and the second server 104 may be designed according to a distributed storage (Ceph) live architecture, Ceph is a unified distributed storage system, and is designed to provide better performance, reliability and expandability. The second server 104 may send a multiple copy request to the first server 102 after storing the processed power data in the pending power service request and before feeding back the processing completion information to the user terminal, and the first server 102 may receive the multiple copy request sent by the second server 104. Among them, the existence of multiple copies is a necessary means to improve the reliability, availability, performance and scalability of a distributed system. Replication may increase system reliability, and multiple replicas may be used for offloading, such as a master-to-multiple-slave structure of a database, and may also be used to speed response times, such as cdn, which may allow replication to have utility for enhancing system availability and scalability.
The first server 102 may receive multiple copies of the replication request sent by the second server 104. The multiple copy requests may include processed power data obtained by the second server processing the power service request sent by the user terminal. The first server 102 may obtain the processed power data in the multiple copy request and store the processed power data in the first database of the first server 102 to obtain the stored power data stored in the first server 102. Thereby achieving real-time data synchronization of the first server 102 and the second server 104. After the first server 102 synchronizes the power data that has just been processed by the second server 104, the first server 102 may send storage completion information to the second server 104, and after the second server 104 receives the storage completion information sent by the first server 102, the second server 104 may return the power service processing completion information to the user terminal after receiving the storage completion information, which represents that the real-time synchronization of the data between the first server 102 and the second server 104 is completed. After receiving the electric power service processing completion information, the user terminal can generate corresponding prompt information, so that the user knows that the electric power service processing is completed. The power service processing completion information may be information in a code form.
For example, taking the power service as power data writing as an example, when a service request writes data, the service request is directed to the primary center, that is, the second server 104, by default through the load device, after the second server 104 finishes storing, a multi-copy replication request may be sent to the standby center, that is, the first server 102, and after the first server 102 finishes replicating the multi-copy, the second server 104 may return 200OK information to the user terminal to prompt that the data writing of the user terminal has been completed.
Through this embodiment, the first server 102 may perform data synchronization of multiple copies with the second server 104 when the second server 104 completes processing of the power service, so that there is no difference between the primary and secondary servers, and real-time increment is implemented, thereby improving backup efficiency of power data disaster tolerance.
In one embodiment, after processing the pending power service request according to the service processing logic and storing the pending power data in the first database of the first server as the stored power data, the method further comprises: and receiving the operation recovery information sent by the second server, and synchronizing the stored power data in the first database with the stored power data in the second database of the second server through the object storage gateway service.
In this embodiment, the first server 102 may process the power service being processed by the second server 104 when the second server 104 fails. The first server 102 may store the power data therein after processing the power service request, so as to obtain the stored power data. At this point, the stored power data at the time of the first server 102 and the stored power data at the time of the second server 104 may be different because the second server 104 may be failing. When the second server 104 resumes normal operation, the first server 102 may receive the resumed operation information sent by the second server 104, and synchronize the stored power data in the first database with the stored power data in the second database of the second server 104 through an RGW (radio Gateway) service. The synchronization between the first database and the second database may be a bidirectional synchronization based on an RGW service in a distributed storage dual live structure, where the RGW service is a storage service supported by a Ceph overall architecture. The data synchronization process between the main server and the standby server and the service request belong to asynchronous operation, and the synchronization time cannot be guaranteed, so that data synchronization can be timely completed between the main server and the standby server through an internal consistency check mechanism, and the consistency of power data is guaranteed.
Through the embodiment, the first server 102 may perform data synchronization of the stored power data with the second server 104 after the second server 104 recovers to operate normally, so as to improve the efficiency of disaster recovery backup of the power data and ensure data consistency between the main server and the standby server.
In one embodiment, as shown in fig. 3, a power data disaster recovery method is provided, which is described by taking the method as an example applied to the second server in fig. 1, and includes the following steps:
step S302, detecting the fault information of the second server, and sending a pending power service request including pending power data sent by the user terminal to the first server; the first server is used for processing the power service request to be processed according to the same service processing logic as the second server, and storing the power data to be processed into a first database of the first server as stored power data.
The user terminal can be a terminal held by a user needing to perform the power service, and the user can perform the corresponding power service through the user terminal; the second server may be a primary server and the first server may be a backup server. The second server 104 may receive the pending power service request from the user terminal under normal conditions, and process the pending power service request sent by the user terminal through the service processing logic of the second server 104 based on the stored power data in the second database of the second server 104. The first server 102 and the second server 104 may be disposed in the same distributed storage dual live architecture.
The first server 102 and the second server 104 may be communicatively connected, and may implement bidirectional synchronization of data and services, when the second server 104 fails, for example, when encountering a natural disaster or a human damage, the second server 104 may send failure information to the first server 102, and the first server 104 may detect the failure information of the second server 104 and perform disaster recovery processing by the first server 102. When the second server 104 fails, the first server 102 may obtain pending power service requests of the second server 104 that are being processed. Wherein, the pending power service request includes pending power data. Because a double-center synchronous mode is adopted between the first server 102 and the second server 104, data processing can be simultaneously performed between the main server and the standby server, and real-time increment is realized, so that the same stored electric power data and the same service processing logic as those of the second server 104 are stored in the first server 102. The stored power data represents power data formed by storing the obtained processed power data after the first server 102 or the second server 104 processes the power service to be processed, that is, the stored power data is power data stored in a database. The service processing logic may be processing logic for the pending power service request, for example, the pending power service may be a data write request, and the first server 102 and the second server 104 have the same storage principle for the pending power service request.
The service processing logic of the first server 102 may be the same service processing logic as that of the second server 102, the first server 102 serves as a standby server, when the second server 102 fails, the pending power service request being processed by the second server 102 may be processed according to the same service processing logic as that of the second server 104, the pending power service request includes pending power data, the first server 102 processes the pending power data to obtain processed power data, the first server 102 may store the processed power data in the first database of the first server 102 as new stored power data, update of the database is implemented, complete processing of the pending power service of the user terminal, implement disaster recovery processing of the power data, and enable the second server 104 serving as a main server to perform disaster recovery processing of the power data through the first server 102 when the second server 104 fails, and the non-inductive switching and the non-inductive processing of the power service are realized.
Step S304, detecting the operation recovery information of the second server, and synchronizing the stored electric power data in the first database with the stored electric power data in the second database of the second server through the object storage gateway service.
The first server 102 may process the power service being processed by the second server 104 when the second server 104 fails. The first server 102 may store the power data therein after processing the power service request, so as to obtain the stored power data. At this point, the stored power data at the time of the first server 102 and the stored power data at the time of the second server 104 may be different because the second server 104 may be failing. When the second server 104 resumes normal operation, the first server 102 may receive the resumed operation information sent by the second server 104, and synchronize the stored power data in the first database with the stored power data in the second database of the second server 104 through an RGW (object storage Gateway) service. The synchronization between the first database and the second database may be a bidirectional synchronization based on an RGW service in a distributed storage dual live structure, where the RGW service is a storage service supported by a Ceph overall architecture. The data synchronization process between the main server and the standby server and the service request belong to asynchronous operation, and the synchronization time cannot be guaranteed, so that data synchronization can be timely completed between the main server and the standby server through an internal consistency check mechanism, and the consistency of power data is guaranteed.
In the power data disaster recovery method, when the second server is detected to be out of order, the to-be-processed power service request which is being processed by the second server is acquired. The first server stores stored power data and service processing logic which are the same as those of the second server, and the stored power data and the service processing logic are obtained by performing data synchronization with the first server when the second server stores the to-be-processed power data in the power service request. The first server processes the power service request to be processed according to the service processing logic, stores the power data to be processed into the first database as stored power data, and when the second server is detected to restore operation, the first server can also perform data synchronization with the second server to restore the data of the second server. Compared with the traditional backup disaster recovery mode based on the local disk, the scheme utilizes the first server which has the same stored power data and service processing logic as the second server to process the power service request which is processed by the second server when the second server fails, thereby realizing the non-inductive processing of the service and improving the backup efficiency of the power data disaster recovery.
In one embodiment, further comprising: receiving a power service request sent by a user terminal, and acquiring to-be-processed power data in the power service request; processing the power service request according to the service processing logic to obtain processed power data, and storing the processed power data to a second database of a second server as stored power data; sending a multi-copy replication request including processed power data to a first server; the first server is used for acquiring the processed power data in the multiple copy replication requests and storing the processed power data in the first database to obtain the stored power data.
In this embodiment, the second server 104 may receive the power service request sent by the user terminal under the normal operation condition, and process and store the to-be-processed power data in the power service request, when the second server 104 completes storing the to-be-processed power data, before returning the processing result to the user terminal, data synchronization may be initiated to the first server 102, and then the first server 102 and the second server 104 may synchronize the service processing logic and the stored power data, thereby ensuring data consistency and processing logic consistency between the first server 102 and the second server 104.
Specifically, the second server 104 may serve as a main server to receive a power service request from the user terminal under a normal operation condition, the second server 104 may receive the power service request sent by the user terminal and obtain the to-be-processed power data in the request, the second server 104 may process the power service request according to the service processing logic and obtain the processed power data, and the second server 104 may store the processed power data in a second database of the second server 104 as the stored power data. After the second server 104 processes the power service request, the processed power data can be obtained. The first server 102 and the second server 104 may be designed according to a distributed storage (Ceph) live architecture, Ceph is a unified distributed storage system, and is designed to provide better performance, reliability and expandability. The second server 104 may send a multiple copy request to the first server 102 after storing the processed power data in the pending power service request and before feeding back the processing completion information to the user terminal, and the first server 102 may receive the multiple copy request sent by the second server 104. Among them, the existence of multiple copies is a necessary means to improve the reliability, availability, performance and scalability of a distributed system. Replication may increase system reliability, and multiple replicas may be used for offloading, such as a master-to-multiple-slave structure of a database, and may also be used to speed response times, such as cdn, which may allow replication to have utility for enhancing system availability and scalability.
The first server 102 may receive multiple copies of the replication request sent by the second server 104. The multiple copy requests may include processed power data obtained by the second server processing the power service request sent by the user terminal. The first server 102 may obtain the processed power data in the multiple copy request and store the processed power data in the first database of the first server 102 to obtain the stored power data stored in the first server 102. Thereby achieving real-time data synchronization of the first server 102 and the second server 104. After the first server 102 stores the processed power data, corresponding processing completion information may also be returned to the second server 104 to notify the second server 104 of the next processing.
Through this embodiment, the first server 102 may perform data synchronization of multiple copies with the second server 104 when the second server 104 completes processing of the power service, so that there is no difference between the primary and secondary servers, and real-time increment is implemented, thereby improving backup efficiency of power data disaster tolerance.
In one embodiment, after sending the multiple copy replication request including the processed power data to the first server, the method further includes: receiving storage completion information sent by a first server; and returning the electric power service processing completion information corresponding to the electric power service to the user terminal.
In this embodiment, after the first server 102 performs the multi-copy replication, corresponding storage completion information may be returned to the second server 104. The second server 104 may receive the storage completion information sent by the first server 102, and return the electric power service processing completion information corresponding to the electric power service to the user terminal. And the user terminal can generate corresponding prompt information based on the service processing completion information to prompt the user that the service processing is completed.
Specifically, after the first server 102 synchronizes the power data that has just been processed by the second server 104, the first server 102 may send storage completion information to the second server 104, and after the second server 104 receives the storage completion information sent by the first server 102, the second server 104 may return the power service processing completion information to the user terminal after receiving the storage completion information, where the storage completion information represents that the real-time synchronization of the data between the first server 102 and the second server 104 is completed. After receiving the electric power service processing completion information, the user terminal can generate corresponding prompt information, so that the user knows that the electric power service processing is completed. The power service processing completion information may be information in a code form.
For example, taking the power service as power data writing as an example, when a service request writes data, the service request is directed to the primary center, that is, the second server 104, by default through the load device, after the second server 104 finishes storing, a multi-copy replication request may be sent to the standby center, that is, the first server 102, and after the first server 102 finishes replicating the multi-copy, the second server 104 may return 200OK information to the user terminal to prompt that the data writing of the user terminal has been completed.
Through this embodiment, the first server 102 may perform data synchronization of multiple copies with the second server 104 when the second server 104 completes processing of the power service, so that there is no difference between the primary and secondary servers, and real-time increment is implemented, thereby improving backup efficiency of power data disaster tolerance, and the second server 104 sends service processing completion information to the user terminal after the first server 102 completes multiple copies, thereby ensuring that the first server 102 and the second server 104 can maintain consistency of data and service logic, and improving efficiency of power data disaster tolerance.
In one embodiment, as shown in fig. 4, fig. 4 is a schematic flow chart of a power data disaster recovery method in another embodiment. As can be seen from fig. 4, the second server 104(Cluster1) and the first server 102(Cluster2) are designed in a distributed storage dual active architecture, two-way synchronization of data can be performed between the first server 102 and the second server 104 through the RGW service, and the servers and the user terminals can be connected through load balancing. Take the service request as an example of writing power data. When the service request writes data, the data is directed to the primary center, that is, the second server 104, by default through the load device, and after the primary center stores the multiple copies that are copied to the standby center (the first server 102), the second server 104 returns 200OK to the user terminal on the service side, thereby completing data writing. Meanwhile, data synchronization from the main center cluster to the standby center cluster can be performed, service data disaster tolerance is achieved, and storage and network efficiency are optimized. When the main center fails, the load transfers the service request to the standby center, and the storage principle of the standby center is consistent with that of the data center. After the data center is recovered, data synchronization can be carried out between the main center and the standby center to ensure the consistency of the data of the double centers.
The main and standby data synchronization process and the service request belong to asynchronous operation, and the synchronization time cannot be guaranteed, so that data synchronization can be completed between the main and standby clusters in time through an internal consistency check mechanism to guarantee the consistency of data.
Through the embodiment, the first server which has the same stored power data and service processing logic with the second server is used for processing the power service request which is processed by the second server when the second server fails, so that the non-inductive processing of the service is realized, and the backup efficiency of power data disaster tolerance is improved. Moreover, for disaster recovery of the unstructured power data, the operation of the service system can be recovered in a short time through the embodiment, the requirement of the service on the reliability of the information system is met, and finally, when the main center encounters natural disasters or artificial damages, the main center can be realized. In addition, seamless or quick switching of the service can be realized, thereby ensuring the service continuity. Due to the double-center synchronous mode, data processing is carried out between the main and standby devices at the same time, and real-time increment is achieved. And because the data is not different, the main and standby can be switched, the service is realized noninductively, and the switched main and standby can be used.
