it should be noted that cluster deployment is a deployment form commonly used for production. A cluster is typically made up of two or more node machines (servers) that provide a unified set of web services or applications to users. The implementation principle is that each node is interconnected by corresponding hardware and software, each cluster node has own process, and the processes of each node can communicate with each other, and the nodes are revealed to a user in the form of a single system through cooperation. Cluster deployments have high availability, one server fails and other servers can continue to provide access to services and applications that are needed by the user. This means that the downtime is shorter and the impact on the traffic is smaller. Meanwhile, the expandability and the elasticity of cluster deployment are extremely strong, operation and maintenance personnel can efficiently and lowly expand or reduce resources in a mode of increasing or reducing nodes in the clusters, and meanwhile, each node can also share flow in an average way by combining a load mechanism.

It should be noted that, the central node cluster of the mail system is communicated with each service cluster network, and can be accessed through different domain names.

As an alternative embodiment, mail services include, but are not limited to, forwarding mail, mail filtering and sorting, archiving of mail, encrypting mail.

As an alternative embodiment, the mail service request includes, but is not limited to, a first account name, a second account name, and mail content.

Step S204, forwarding the mail service request to the first service cluster through the central node cluster, and providing a mail service for an account corresponding to the first account name through the first service cluster.

As an alternative embodiment, the division of the service clusters may be according to function division, object type division, and load balancing division, which is not further limited in the embodiments of the present application.

In an exemplary embodiment, the determining, by the central node cluster, the first service cluster corresponding to the first account name may be implemented by the following steps S11-S12:

step S11: acquiring a first list through the central node cluster, wherein the first list is provided with account names of accounts served by different service clusters of the mail system;

step S12: and determining a first service cluster corresponding to the first account name according to the first list through the central node cluster.

As an alternative embodiment, it is assumed that the first list has recorded therein: the account names of the first service cluster service are A, B, C, D, E and F, the account names of the second service cluster service are 1,2,3,4 and 5, and then the central node cluster can determine the first service cluster corresponding to the first account name according to the first list.

In an exemplary embodiment, the providing, by the first service cluster, the mail service for the account corresponding to the first account name may be implemented by the following steps S21 to S22:

step S22: and determining a second service cluster for providing mail service for the account corresponding to the second account name through the first service cluster, and sending the mail content carried in the mail service request to the account corresponding to the second account name through the second service cluster.

In an exemplary embodiment, the determining, by the first service cluster, the second service cluster for providing the mail service for the account corresponding to the second account name may be implemented by the following steps S31-S32:

step S31: sending a first request message to a central node cluster through the first service cluster, wherein the first request message carries the second account name;

step S32: and acquiring the domain name of a second service cluster sent by the central node cluster in response to the first request message through the first service cluster.

That is, the first service cluster may send a message to the central node cluster requesting to determine a second service cluster providing a mail service for an account corresponding to the second account name, and further forward the mail service request to the second service cluster.

Through the steps S202-S204, when the central node cluster of the mail system obtains the mail service request, the central node cluster determines the first service cluster corresponding to the first account name, and then sends the service request to the corresponding first service cluster, and the first service cluster provides the mail service. The mail service is provided for the user through the multi-service cluster, the problem that the existing mail system is poor in processing effect when processing large-scale mails is solved, and the efficiency of processing and providing the mail service for the mail system is improved. In addition, the mail service is provided for the user through the multi-service cluster, so that the mutual isolation among the resources can be improved, and the technical effect of enhancing the availability of the resources is achieved.

In an exemplary embodiment, after determining, by the central node cluster, the first service cluster corresponding to the first account name, the following step S41 is further provided:

step S41: sending target information to a client under the condition that the mail service request acquired by the central node cluster is sent by the client;

it should be noted that, the client is a client that sends the mail service request, the target information carries a domain name of the first service cluster, and the target information is used to instruct the client to send the service request to the first service cluster when sending the service request of the account corresponding to the first account name.

As an alternative embodiment, when the account corresponding to the first account name accesses the mail system for the first time, the corresponding client will automatically send the mail service request to the central node cluster.

step S52: sending a second request message to the central node cluster under the condition that the first account name is not located in the second list so as to determine the service cluster for providing mail service for the account corresponding to the first account name;

step S53: and under the condition that the first account name is located in the second list, providing mail service for the account corresponding to the first account name through the third service cluster.

That is, assuming that the third service cluster obtains the mail service request, the third service cluster queries the first account name in the second list stored by the third service cluster, if the second list has the first account name, the service cluster which indicates that the account corresponding to the first account name currently provides the mail service is the third service cluster, if the second list is not in the second list, the third service cluster needs to send query information to the central node cluster according to the first account name, queries the account corresponding to the first account name and provides the mail service, and then forwards the request to the corresponding service cluster for processing.

As an optional embodiment, when the account corresponding to the first account name uses the mail system for the second time, the corresponding client may access the corresponding service cluster through the saved information.

In an exemplary embodiment, the above method further has the following step S61:

step S61: and sending the account name of the account served by the service cluster to the central node cluster at regular time through the service cluster of the mail system, wherein the service cluster comprises the first service cluster.

As an optional embodiment, through the above step S61, it may be determined that the account name stored in the central node cluster is consistent with the account name stored in each service cluster.

It will be apparent that the embodiments described above are only some, but not all, of the embodiments of the present application. For better understanding of the above method, the following description will explain the above process with reference to the examples, but is not intended to limit the technical solutions of the embodiments of the present application, specifically:

based on the distributed architecture and the multi-cluster deployment mode, the user group is accessed into different clusters deployed with the same service through the control of the central node cluster, so that the flexibility and the high availability are achieved. Fig. 3 is a schematic diagram of a multi-service cluster structure according to an embodiment of the present application, where, as shown in fig. 3, a central node cluster is connected to each service cluster network and accesses the central node cluster through different domain names. The user logs in the central node cluster for the first time, the central node cluster is connected with the central node cluster and acquires the user node information, the central node cluster returns the server information (namely the domain name of the service cluster for providing service for the user) to the client, and the client caches the server information to the local. When the user uses the domain name for the second time, the user can log in by accessing any domain name, at the moment, the service cluster receiving the request can firstly compare the user information in the current cluster, and if the user is the user managed by the current cluster, the request is processed locally; if not, the user node position is inquired from the central node cluster according to the user name, and the service request is forwarded to the corresponding cluster. Fig. 4 is a schematic diagram of a user request processing flow in a multi-cluster deployment mode in the embodiment of the present application, where, as shown in fig. 4, each service cluster stores a user list managed by the cluster, and a central node cluster stores attribution information between a user and each service cluster, where the information is synchronized by each service cluster to the central node at a timing.

In addition, the central node, in addition to providing the underlying mail services and data storage, provides three interfaces to the split nodes: namely, the user registers, inquires the node position of the user and modifies the password, and the center node needs to keep smooth conversation with other three partial nodes. Services deployed by each service node are consistent, including a global information network (World Wide Web, web) server deployed with a high availability agent (High Availability Proxy, short for Haproxy), an AP server deployed with a ng-ginx, a hypertext preprocessor (Hypertext Preprocessor, PHP, running manager (FastCGIProcess Manager, FPM), monitoring, analysis and automation (MAA) in the server domain, and the like; a cluster of Elastic Search (ES) and Redis and a database server and cos object storage are jointly deployed.

From the above, the architecture mode not only has the advantages of high reuse degree of the distributed architecture system module and convenient development, but also has the same service and contained resource types deployed among multiple clusters. The method has good performance in the aspects of availability, disaster tolerance and scalability. In addition, the method and the system are in a form that multiple clusters are oriented to different grouping users, and resources are reasonably distributed by taking a central node as overall control. The method not only improves the mutual isolation among resources and increases the usability, but also supports the daily operation and maintenance analysis of the mail system by a large-scale organization to a greater extent due to the characteristics that users and the resources are stable and correspond to each other, and is more beneficial to traffic monitoring and analysis. The present application perfects the current more common solution to aim at dividing the web services and software services of the mail system into several layers based on the distributed concept, resulting in the lack of support means for enterprise-level users.

From the description of the above embodiments, it will be clear to a person skilled in the art that the method according to the above embodiments may be implemented by means of software plus the necessary general hardware platform, but of course also by means of hardware, but in many cases the former is a preferred embodiment.
