With the rapid development of traffic, the dependence on Redis is getting heavier and heavier, and the accompanying system problems are also beginning to increase. In the application mode at the present stage, in the fault recovery of the Redis, more manual intervention procedures are needed. In the fault recovery requiring cluster switching, each application is also required to manually update the relevant configuration and restart the application.

Detailed Description
The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.
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.
Referring to fig. 1, fig. 1 is a flowchart of an information processing method according to an embodiment of the present invention, which is executed by an SDK, as shown in fig. 1, and includes the following steps:
In practical application, a client sends a service subscription request to an SDK by specifying a mode of subscribing to a certain service. The service subscription request may include information of a service to which the client desires to subscribe, and the like, and the SDK may be set in the client.
And step 102, acquiring first attribute information of the first Redis cluster from the service management device according to the service subscription request.
In this embodiment of the present invention, the service management device may be, for example, Consul. Specifically, the SDK may determine the first Redis cluster from the candidate clusters according to the service subscription request, for example, the SDK may arbitrarily select one cluster from the selectable clusters as the first Redis cluster, or determine the first Redis cluster corresponding to the service subscription request according to the service subscription request of the client. And then, the SDK sends the information of the first Redis cluster to the service management equipment, and acquires the first attribute information of the first Redis cluster from the service management equipment. Since each cluster needs to register with the service management device before providing the service, so as to write its own information, such as a name, an IP address, and the like, into the service management device, the service management device may determine the first Redis cluster from the registered clusters according to the information (such as a name, an identifier, and the like) of the first Redis cluster sent by the SDK, and acquire the attribute information thereof.
In general, a Redis cluster may include at least a primary cluster and a backup cluster, where the primary cluster refers to a currently designated cluster providing a service and the backup cluster refers to a cluster acting as a backup. As to which cluster is used as the primary cluster and which cluster is used as the standby cluster, the designation can be made according to actual needs.
Wherein the first attribute information includes: and the identification of the current main cluster, the IP address of the current main cluster, the identification of the current standby cluster and the IP address of the current standby cluster in the first Redis cluster. The meaning of "current master cluster" refers to a cluster designated as a master cluster in the first Redis cluster when the SDK requests to acquire information of the first Redis cluster, and similarly, the meaning of "current standby cluster" refers to a standby cluster in the first Redis cluster when the SDK requests to acquire information of the first Redis cluster.
In the process of establishing connection, the SDK configures an IP address and a connection port according to the acquired IP addresses of the master and the slave clusters, and the like, so as to establish connection between the client and the first Redis cluster. The listening of the first Redis cluster may be initiated after the connection is established, or during the connection establishment, or also after a service subscription request of the client is received. Specifically, a listener may be set in the SDK, and is used to implement listening to the first Redis cluster.
Specifically, the SDK may send a first request to the service management device, where the first request is used to request the service management device for the second attribute information of the first Redis cluster. Then, the SDK receives a first response sent by the service management device, where the first response includes second attribute information of the first Redis cluster, where the second attribute information includes: and the identification of the current main cluster, the IP address of the current main cluster, the identification of the current standby cluster and the IP address of the current standby cluster in the first Redis cluster.
And step 104, updating the connection between the client and the first Redis cluster when the first Redis cluster is monitored to be changed.
Specifically, when the first attribute information is different from the second attribute information, the connection between the client and the first Redis cluster is updated. In practical applications, a first Redis cluster may have a change in information (e.g., an IP address change) due to a failure of a certain cluster in the cluster, or may also have a change in information due to a capacity expansion/reduction operation performed by a device, for example, an IP increase/decrease — that is, a change of the IP of a main cluster indicates that the first Redis cluster performs a capacity expansion/reduction operation; or when the IP of the main cluster is changed, the change of the main cluster of the first Redis cluster is indicated; then, at this time, the second attribute information returned by the service management apparatus may be different from the first attribute information.
Therefore, when the second attribute information indicates that the first Redis cluster is subjected to scaling, or the second attribute information indicates that a primary cluster and/or a standby cluster in the first Redis cluster are changed, that is, the first attribute information is different from the second attribute information, the connection between the client and the first Redis cluster may be updated according to the second attribute information. Specifically, in the updating process, the connection port, the IP address, and the like of the existing connection may be updated according to the identifier of the current master cluster, the IP address of the current master cluster, the identifier of the current standby cluster, the IP address of the current standby cluster, and the like in the second attribute information.
In the embodiment of the invention, after the connection between the first Redis cluster and the client is established according to the service subscription request of the client, if the change of the first Redis cluster is monitored, the connection between the client and the first Redis cluster is updated. It can be seen from the above description that the SDK can monitor the change of the first Redis cluster in time and update the connection in response to the change, and no manual participation is needed in this process, so that the scheme of the embodiment of the present invention can shorten the recovery time of the service, and can achieve the effect of unaware switching.
Referring to fig. 2, fig. 2 is a flowchart of an information processing method provided by an embodiment of the present invention, which is executed by a service management device, and as shown in fig. 2, includes the following steps:
In the embodiment of the present invention, the service management device includes Consul. Through the interface provided by Consul, a cluster that has been successfully deployed may be registered in the Consul in a service manner, including registering information such as an IP address and an identifier of the cluster in the Consul. And the cluster registration is used for completing the realization of cluster service.
Specifically, in this step, the service management device receives information of the first Redis cluster sent by the SDK, and sends, to the SDK, first attribute information of a first Redis cluster in the clusters according to the information of the first Redis cluster, where the first Redis cluster is a cluster registered in a service manner, and the first attribute information includes: and the identification of the current main cluster, the IP address of the current main cluster, the identification of the current standby cluster and the IP address of the current standby cluster in the first Redis cluster.
Specifically, in this step, the service management device receives a first request sent by the SDK, where the first request is used to request second attribute information of the first Redis cluster. When the first Redis cluster is scaled or a primary cluster and/or a standby cluster in the first Redis cluster are changed, the service management device sends a first response to the SDK, where the first response includes second attribute information of the first Redis cluster, where the second attribute information includes: and the identification of the current main cluster, the IP address of the current main cluster, the identification of the current standby cluster and the IP address of the current standby cluster in the first Redis cluster.
In the embodiment of the invention, after the connection between the first Redis cluster and the client is established according to the service subscription request of the client, if the change of the first Redis cluster is monitored, the connection between the client and the first Redis cluster is updated. It can be seen from the above description that the SDK can monitor the change of the first Redis cluster in time and update the connection in response to the change, and no manual participation is needed in this process, so that the recovery time of the service can be shortened by using the scheme of the embodiment of the present invention.
Referring to fig. 3, fig. 3 is a schematic diagram of an information processing system of an embodiment of the present invention. The system may include: client (client)301, SDK302, service management device Consul303, Redis logical cluster 304. In fig. 3, two Redis logical clusters Redis _ server1 and Redis _ server2 are shown, and each Redis logical cluster is composed of two physical Redis clusters, where one physical Redis cluster is a master cluster and the other is a backup cluster. As shown in fig. 3, redis _ server1 includes clusters phycluster1, phycluster 2; redis _ server2 includes clusters phycluster3, phycluster 4. Wherein, one of phycyluster 1 and phycyluster 2 can be designated as a main cluster, and the other is designated as a standby cluster; one of phycyluster 3 and phycyluster 4 may be designated as the primary cluster and the other as the backup cluster.
Referring to fig. 4, fig. 4 is a flowchart of an information processing method according to an embodiment of the present invention, and as shown in fig. 4, the method includes the following steps:
The registered information includes an IP address, cluster master/slave role information (whether a cluster is a master cluster or a slave cluster), and the like. And registering the deployed logic cluster to Consul, namely completing the service realization of the cluster.
For example, a client may subscribe to the services of the redis _ server1 cluster using the SDK by specifying a manner of subscribing to the redis _ server1 service.
Assuming that the client specifies subscription to the redis _ server1 service, the SDK may accordingly specify the service alias as redis _ server1 to Consul. Or, according to the service subscribed by the client, the SDK may also establish a connection with the client with a server cluster corresponding to another subscribed service, and specify a required alias of the corresponding service from each cluster.
And 405, establishing connection for the client by the SDK according to Consul, so as to realize access to the cluster.
For example, the SDK may send a request to Consul to request information for redis _ server 1.
If the current service-providing cluster needs to be expanded due to the fact that the current service-providing cluster cannot support the current application service requirement, or when the cluster fails and some nodes are unavailable, information of the current service-providing Redis cluster may change.
For example, the roles of the master and slave clusters change, such as the master cluster is reduced to the slave cluster, the slave cluster is increased to the master cluster, and the like, and the IP address changes.
And step 408, if the cluster which provides the service currently changes, the SDK updates the connection, so that the cluster is switched to a new Redis cluster.
By comparison, if the information received by the SDK for redis _ server1 is different, then the SDK updates the connection. Alternatively, in step 407, the Consul may send the information of redis _ server1 to the SDK only when it is determined that the information of redis _ server1 changes, so that the SDK is not required to perform the determination, and the service recovery time may be further shortened. The SDK may store the updated connection in a management container.
Specifically, after the watch has monitored the second attribute information, first, we determine whether there is a change according to the existing metadata information (first attribute information) and the second attribute information, and if the change is detected, then: firstly, updating metadata information (first attribute information) maintained in the SDK, wherein the metadata information (first attribute information) comprises related information such as an IP address, interface information (port) and an authorization code (password) of a main/standby cluster, then, taking out connection objects (at least comprising the main cluster and the standby cluster) of a redis cluster (first cluster) created in a current application (client), recreating a group of new redis connection objects by using the latest metadata information of one object, and finally, replacing the old connection objects with the new redis connection objects. In this way, a non-inductive service cluster switching operation is completed, the process is completely carried out in the SDK, for each application using the SDK, the series of operations which are carried out by the application are not known or need not be known, and the application only needs the concerned SDK to provide an available connection object.
As can be seen from the above description, in the embodiment of the present invention, the Redis cluster is serviced, so as to provide the capability of the Redis to its user in a service manner. After the application is served, disaster recovery and backup switching of the Redis cluster can be performed under the condition of no sense, and meanwhile, the dependence of the application on the relevant configuration of the Redis is reduced. In this mode, if a Redis cluster fails or a cluster needs to be switched due to capacity expansion/reduction operation, the role of the cluster group in the logical cluster is changed, the cluster capable of normally providing capacity is set as a main cluster, and the failed cluster is set as a standby cluster, so that the change of the service cluster is triggered, and the SDK can monitor and respond to the change in time to update the connection.
In the above process, the monitoring mechanism of the SDK is used to implement the change of the connection, so that the client does not feel any operation, and the purpose of switching the clusters without sensing can be achieved. Because the SDK can update the connection in response to the change of the cluster, the scheme of the embodiment of the invention reduces the manual participation, thereby shortening the time of fault recovery and improving the application stability. In addition, in the embodiment of the invention, the access to the cluster can be completed only by specifying the used service name by the client, and the client does not need to perform complicated configuration of relevant information such as the cluster IP, relevant connection parameters and the like, thereby simplifying the complexity of the access configuration of the client.
The embodiment of the invention also provides an information processing device which is applied to the SDK. Referring to fig. 5, fig. 5 is a block diagram of an information processing apparatus according to an embodiment of the present invention.
