Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a service updating method, a device and a system, based on the fact that service updating data used for service nodes to perform service updating is divided into a plurality of sub updating data in advance, a plurality of service nodes to be subjected to service updating share the diffusion of each sub updating data, and data used for service updating of any service node are obtained by collecting all sub updating data from other associated service nodes and then combining the sub updating data.

Fig. 1 is a schematic view of an application scenario of service update provided in an embodiment of the present application, as shown in fig. 1, a plurality of service nodes to be updated for service are involved, where the service nodes are hosts of an internet service or a cloud computing service, and may be physical machines, virtual containers, or server software, and in a stage of primary distribution of sub-update data, that is, a process of distributing a plurality of sub-update data obtained by splitting the service update data to a plurality of service nodes for the first time, each sub-update data is distributed to at least one service node; and then entering a diffusion stage of the sub-update data, with the continuous diffusion of the sub-update data, the number of service nodes where each sub-update data is located is increased, the number of the sub-update data stored in each service node is also increased, and after any service node collects all the sub-update data, the service nodes are combined to obtain complete service update data, and local service update is completed by using the service update data. When the product functions and services need to be updated and deployed, related software or configuration on all service nodes to be updated by the services is updated, and the method has the characteristics of cross-machine room, distributed decentralization, fault-tolerant mechanism, system independence and hardware independence in the service updating process, fully utilizes network resources and computing resources among service nodes and machine rooms, and ensures that sub-update data is rapidly, efficiently, safely and reliably diffused in the multi-service nodes. Finally, each service node to be updated is merged to obtain a complete service update data, thereby realizing the service update of multiple service nodes.

Fig. 2 is a first flowchart of a service update method provided in an embodiment of the present application, where the method in fig. 2 can be executed by the service node 100 in fig. 1, and is suitable for service update deployment of internet services and cloud computing services, as shown in fig. 2, where the method at least includes the following steps:

s201, in a plurality of service nodes to be updated, acquiring a plurality of sub-update data from a plurality of service nodes other than a first service node, where the plurality of sub-update data are obtained by dividing the service update data in advance, the first service node is any one of the plurality of service nodes to be updated, and since any one service node not only participates in the diffusion of the sub-update data, but also needs to perform service update, in the process that the sub-update data is diffused from one service node to another service node, the transmitted sub-update data is a data copy of a data sub-block obtained by dividing the service update data. The plurality of sub-update data acquired by the first service node may be from a part of service nodes other than the first service node, or may be from all service nodes other than the first service node.

S202, merging the obtained multiple sub-update data to obtain service update data for service update, specifically, after all the sub-update data are obtained, restoring the multiple sub-update data to the service update data before being split.

And S203, updating the service of the first service node according to the service updating data obtained by merging, specifically, after the complete service updating data is obtained by merging a plurality of sub-updating data, if the current service is updated to the upgrade of the original application service, replacing the original service data related to the service to be upgraded with the service updating data, if the current service is updated to a newly added application service, adding the service updating data to the original service data, and restarting the service of the service node.

For example, for a newly added "earning and reward for parcel and parcel" function in a pay for treasure application, the service update data for implementing the "earning and reward for parcel and parcel" application service needs to be divided into a plurality of sub update data, then steps S201 to S203 are adopted so that each service node providing the application service acquires all the sub update data and merges the sub update data into service update data, and each service node updates the local application service by using the service update data, thereby providing a corresponding application service to the client.

In the embodiment of the application, the service updating data used for the service node to update the service is divided into the plurality of sub updating data in advance, the plurality of service nodes to be updated share the diffusion of the sub updating data, and the data used for updating the service by any service node is obtained by collecting all the sub updating data from other associated service nodes and then combining the sub updating data, so that the computing resources and the network resources of the plurality of service nodes are effectively utilized, the service updating efficiency of the multi-service node is improved, and the service updating of each service node is quickly, efficiently and safely realized.

As shown in fig. 3, before obtaining a plurality of sub-update data from a plurality of service nodes other than the first service node in a plurality of service nodes to be updated by the service S201, the method further includes:

s204, receiving a service updating request, wherein the service updating request carries data identifiers of all sub-updating data obtained by dividing service updating data; specifically, each sub-update data corresponds to a data identifier, for example, a data sequence number may be used as the data identifier of the sub-update data, taking the example that the service update data is divided into m sub-update data, the data identifier of the first sub-update data is 1, and the data identifier of the last self-update data is m.

Correspondingly, in the step S201, obtaining a plurality of sub-update data from a plurality of service nodes other than the first service node among the plurality of service nodes to be updated by service specifically includes:

s2011, in a plurality of service nodes to be updated, according to the received service update request, respectively obtaining sub-update data corresponding to each data identifier from a plurality of service nodes other than the first service node.

In specific implementation, as shown in fig. 4a, in N service nodes to be serviced and updated, service update data is uploaded to any service node (e.g., service node k), and after the service node receives the service update data, the service update data is divided into a plurality of sub update data (e.g., m sub update data); in a plurality of service nodes to be served and updated, as shown in fig. 4b, selecting a target number of service nodes as initial service nodes (e.g., the number of the initial service nodes is x, x is less than or equal to N), and distributing a plurality of sub-update data to the plurality of initial service nodes (e.g., distributing m sub-update data to x initial service nodes), at this time, for each initial service node, the initial service node receives at least one sub-update data, and for each sub-update data, the sub-update data exists at least on one initial service node, which is a primary distribution stage of the sub-update data, wherein if a first service node belongs to the initial service node, a service update request of a service node k is received; and if the first service node does not belong to the first service node, receiving a service update request of the service node k or any first service node. Then, a diffusion stage of the sub update data is entered, as shown in fig. 4c, each sub update data is diffused among a plurality of service nodes, and finally, each service node acquires all the sub update data, as shown in fig. 4d, the acquired plurality of sub update data are merged, and the service update data for service update is obtained.

Specifically, for the case that the first service node belongs to the originating service node, the receiving, by the S204, the service update request specifically includes:

receiving at least one child update data and update data division information that are distributed for the first time, wherein the update data division information includes: and the data identification of all the sub-updating data obtained by dividing the service updating data, and each sub-updating data is distributed to at least one service node.

If the first service node participates in the initial distribution stage of the sub-update data, the service update request received by the first service node can simultaneously carry at least one piece of sub-update data and update data segmentation information, after the first service node receives the at least one piece of sub-update data distributed for the first time, the first service node participates in the subsequent diffusion stage of the sub-update data, transmits the sub-update data stored locally to the service node needing the sub-update data, and acquires the sub-update data which does not exist locally from other service nodes.

Aiming at the condition that the first service node does not belong to the first service node, the first service node directly enters the diffusion stage of the sub-update data, the service update request received by the first service node can only carry the update data segmentation information, the sub-update data which does not exist locally is obtained from other service nodes according to the update data segmentation information, and after the sub-update data is obtained, if the sub-update data obtaining request is received, the sub-update data which is stored locally is transmitted to the service node which needs the sub-update data.

Further, considering that the sub-update data cannot be normally diffused to all the service nodes due to the fact that data packet loss may exist during initial distribution or an abnormality occurs when the service node does not diffuse the received sub-update data to other service nodes, in order to ensure that each service node to be updated by service can acquire all the sub-update data, each sub-update data obtained by dividing the service update data is distributed to at least two service nodes, that is, the same sub-update data is distributed to two initial service nodes.

Specifically, in the initial distribution stage of the sub-update data, in the process of distributing the plurality of sub-update data to the plurality of initial service nodes, the same sub-update data is distributed to at least two initial service nodes, at this time, in the plurality of service nodes to be updated, each sub-update data is stored in at least two service nodes, so that even if a certain service node is abnormal, the sub-update data can be obtained from another service node, it is ensured that each sub-update data can be normally spread to all service nodes, and further, it is ensured that each service node to be updated can obtain all sub-update data, and the success rate of distributing the service update data is improved.

As shown in fig. 5, the step S2011 of obtaining, from a plurality of service nodes to be updated by the service, sub-update data corresponding to each data identifier according to the received service update request, includes:

s20111, respectively obtaining sub-update data storage information of a plurality of service nodes other than the first service node, where the sub-update data storage information includes: and the data identification of the sub-updating data stored on the service node.

S20112, for each data identifier in the service update request, determining whether the first service node has sub-update data corresponding to the data identifier; specifically, according to a preset sequence, whether sub-update data corresponding to each data identifier exists locally or not is inquired one by one, and if not, the sub-update data is acquired from a service node which stores the sub-update data.

If not, executing S20113, selecting a service node as a target service node according to the storage information of each sub-update data and the target data identifier corresponding to the sub-update data which does not exist locally, and acquiring the sub-update data corresponding to the target data identifier from the target service node.

After the first service node acquires the sub-update data storage information of each service node except the first service node, the first service node can determine in which service nodes each sub-update data is distributed, and further can acquire the sub-update data which does not exist locally from the target service node in a targeted manner until the sub-update data corresponding to all the data identifiers is stored locally, specifically, the first service node can acquire the sub-update data corresponding to different data identifiers from at least two different service nodes simultaneously, and all the service nodes can acquire the sub-update data required by the first service node simultaneously, and distribute the data processing load and the data transmission load to all the service nodes, so that the service update data acquisition time is greatly saved, and the service update efficiency and the success rate of the multi-service node are improved.

Further, considering that in the process of determining the target service node, if the number of service nodes to be serviced and updated is large, the number of the obtained sub-update data storage information is also large, and to improve the efficiency of determining the target service node, based on this, the step S20113 selects one service node as the target service node according to each sub-update data storage information and the target data identifier corresponding to the sub-update data that does not exist locally, and specifically includes:

determining sub-update data distribution information according to each sub-update data storage information, wherein the sub-update data distribution information comprises: and each data mark in the service updating request is the information of the service node where the corresponding sub updating data is located.

And selecting one service node as a target service node according to the sub-update data distribution information and the target data identifier corresponding to the locally nonexistent sub-update data.

Specifically, after receiving the sub-update data storage information of a plurality of service nodes except for the sub-update data storage information, the received sub-update data storage information is summarized to obtain sub-update data distribution information, in the sub-update data distribution information, the corresponding relationship between each data identifier and the information of the service node storing the sub-update data corresponding to the data identifier is directly inquired, for example, data identifier 1-service node a \ B \ C, namely, the sub-update data corresponding to data identifier 1 is stored in service node a, service node B and service node C, if the sub-update data corresponding to data identifier 1 needs to be acquired, at this time, one of the service node a, service node B and service node C can be selected as the target service node, so that the sub-update data corresponding to the target data identifier is distributed in which service nodes, and quickly positioning to the target service node.

Further, in order to more fully utilize the computing resources and network resources of each service node, avoid the situation that the load rate of a certain service node is very high and the load rates of other service nodes are very low, and achieve the effect of load balancing of multiple service nodes, based on this, according to the sub-update data distribution information and the target data identifier corresponding to the sub-update data which does not exist locally, one service node is selected as a target service node, which specifically includes:

and taking a plurality of service nodes which have stored sub-update data corresponding to target data identification as alternative service nodes based on the sub-update data distribution information, wherein the target data identification is the data identification corresponding to the sub-update data which does not exist locally.

And determining the candidate service node with the lowest load rate as the target service node according to the load rate of each candidate service node.

Specifically, in the process of selecting the target service node, the load condition of the alternative service node is referred to, and the alternative service node with the lowest load rate is determined as the target service node under the condition that the plurality of service nodes have sub-update data corresponding to the target data identifier, so that the computing resources and the network resources of each service node can be more fully utilized, the effect of load balancing of the plurality of service nodes is achieved, and the service update efficiency of the plurality of service nodes is further improved.

Specifically, after obtaining the sub-update data corresponding to the target data identifier from the target service node, the method further includes:

and if the sub-updating data fails to be obtained, reselecting the next target service node according to the sequence of the load rate from low to high, and obtaining the sub-updating data corresponding to the target data identifier from the reselected target service node.

In the case that only one service node stores the sub-update data corresponding to the target data identifier, the required sub-update data is continuously acquired from the target service node after the target service node is recovered. In order to avoid the situation, in specific implementation, in the initial distribution stage of the sub-update data, the same sub-update data is distributed to at least two first-sending service nodes, so that the at least two service nodes can be ensured to store the sub-update data corresponding to the target data identifier; in addition, even if the same sub-update data is distributed to only one initial service node in the initial distribution stage of the sub-update data, the sub-update data corresponding to the target data identifier can be stored in at least two service nodes along with the continuous diffusion of the sub-update data, a data acquisition failure redundancy mechanism is provided, and the service update data distribution success rate is improved.

Specifically, in the service updating process, if the sub-update data acquisition fails, it is indicated that the target service node is abnormal, and at this time, the first service node reselects the next target service node.

In addition, when the abnormal target service node returns to normal, the target service node continues to execute the following steps: respectively acquiring sub-update data storage information of a plurality of service nodes except the service node; aiming at each data identifier in the service updating request, judging whether sub-updating data corresponding to the data identifier exists locally; if not, selecting a service node as a target service node according to the latest version of each sub-update data storage information and the data identifier, and acquiring the sub-update data corresponding to the data identifier from the target service node until all the sub-update data are acquired.

The process for acquiring the sub-update data storage information can be obtained in two ways, specifically:

the first mode is as follows: when the sub-update data of each service node is updated, actively broadcasting the updated sub-update data storage information to other service nodes, specifically, in step S20111, acquiring the sub-update data storage information of a plurality of service nodes other than the first service node respectively specifically includes:

receiving sub-update data storage information broadcasted by a plurality of service nodes except the first service node, wherein the sub-update data storage information is obtained after the plurality of service nodes except the first service node acquire new sub-update data and update local sub-update data storage information.

sending a subdata storage information acquisition request to each service node except the first service node;

and receiving local latest version sub-update data storage information sent by service nodes except the first service node, wherein the sub-update data storage information is sent by the service nodes except the first service node in response to the sub-data storage information acquisition request.

Specifically, for the process of merging sub-update data, in step S202, merging the obtained plurality of sub-update data to obtain service update data for service update, the method specifically includes:

sequencing the obtained plurality of sub-updating data according to the sequence of the data identification from small to large;

and combining the sub-updating data according to the sequencing result to obtain the service updating data for service updating.

For each service node, the service node not only acquires the sub-update data from other service nodes, but also needs to send the sub-update data to the corresponding service node based on the sub-update data acquisition requests of other service nodes, and based on this, the method further includes:

receiving a sub-update data acquisition request sent by each service node except the first service node;

and sending the sub-update data corresponding to the received acquisition request to a corresponding service node, so that the service node receiving the sub-update data judges whether all the sub-update data are stored locally, and if so, performing local service update, namely the first service node also participates in the diffusion of the sub-update data.

For each service node, the service node not only acquires the sub-update data storage information from other service nodes, but also needs to send the local latest version of the sub-update data storage information to other service nodes, and based on this, the method further includes:

and sending the local latest version of the sub-update data storage information to the corresponding service node, so that the service node receiving the sub-update data storage information determines a target service node, and acquires the sub-update data from the target service node.

Specifically, the process for sending the sub-update data storage information may be implemented in two ways, specifically:

the first mode is as follows: when the sub-update data of the first service node is updated, actively broadcasting the updated sub-update data storage information to other service nodes, specifically, sending the local latest version of the sub-update data storage information to the corresponding service node specifically includes:

after new sub-update data are obtained, local sub-update data storage information is updated;

and broadcasting the updated sub-update data storage information to a plurality of service nodes except the first service node.

The second mode is as follows: the method for sending the local latest version of the sub-update data storage information to the corresponding service node includes that the first service node sends the latest version of the sub-update data storage information to the service node after receiving the sub-data storage information acquisition request of the other service nodes, and specifically includes:

receiving a request for acquiring subdata storage information sent by any service node except the first service node;

and transmitting the sub-update data storage information of the local latest version to the service node sending the sub-update data storage information acquisition request.
