step S100, obtaining the resource consumption information of each service on each server in the server cluster to be migrated.
The server cluster to be migrated refers to a server cluster with service migration requirements, the server cluster to be migrated is composed of a plurality of servers, a plurality of services can be operated on each server, resources of the servers are occupied when all the services are operated on the servers in the server cluster to be migrated, in order to ensure that the migrated services can be used normally, before the services are migrated to a target server cluster, resource consumption information of each service on each server in the server cluster to be migrated needs to be acquired, wherein the resource consumption information comprises: CPU consumption information, bandwidth consumption information, memory consumption information, and the like.
Step S101, determining the residual resource information of each server in the target server cluster.
The target server cluster is a server cluster carrying the migrated services, and the target server cluster is composed of a plurality of servers, in this embodiment, the servers in the target server cluster may already have other services running, and the other services consume resource information of the servers, so before migrating each service on each server in the server cluster to the servers in the target server cluster, the remaining resource information of each server in the target server cluster needs to be determined first to determine to which server in the target server cluster each service should be migrated.
The residual resource information represents the available resource condition of each server in the target server cluster, the total resource information of each server can be determined, and the resource consumption information of the service running on the server can be determined, so that the residual resource information of each server in the target server cluster can be determined according to the total resource information and the resource consumption information.
Step S102, migrating the service item data of the service on each server in the server cluster to be migrated to the corresponding server in the target server cluster according to the resource consumption information and the residual resource information.
After the resource consumption information of each service on each server in the server cluster to be migrated and the residual resource information of each server in the target server cluster are obtained, service item data of each service on each server in the server cluster to be migrated can be migrated to the corresponding server in the target server cluster according to the resource consumption information of each service on each server in the server cluster to be migrated and the residual resource information of each server in the target server cluster, so that normal use of the service after migration is ensured, and trouble is not caused to user use.
According to the method provided by the embodiment of the invention, the resource consumption information of each service on each server in the server cluster to be migrated is obtained; determining the residual resource information of each server in the target server cluster; and migrating the service item data of the service on each server in the server cluster to be migrated to the corresponding server in the target server cluster according to the resource consumption information and the residual resource information. Based on the scheme provided by the invention, the automatic migration of the service between the two clusters is realized, so that the migration accuracy is improved, the problem that the service is unavailable after the migration caused by manual completion of the migration work is avoided, the normal operation of the service after the migration is ensured, a large amount of labor cost is saved, and the time required by the service migration is reduced.
Fig. 2 is a flow chart of a method for migrating services between clusters according to another embodiment of the present invention. As shown in fig. 2, the method comprises the steps of:
step S200, obtaining the resource consumption information and the service state information of each service on each server in the server cluster to be migrated.
The server cluster to be migrated refers to a server cluster with service migration requirements, the server cluster to be migrated is composed of a plurality of servers, a plurality of services can be operated on each server, resources of the servers are occupied when all the services are operated on the servers in the server cluster to be migrated, in order to ensure that the migrated services can be used normally, before the services are migrated to a target server cluster, resource consumption information of each service on each server in the server cluster to be migrated needs to be acquired, wherein the resource consumption information comprises: CPU consumption information, bandwidth consumption information, memory consumption information, and the like.
The service state information indicates a current state of the service, for example, being provided with or without the service. The service state information is determined here to facilitate determination of whether or not to run the migrated service on the servers in the target server cluster, i.e., whether or not to provide the service externally, after migrating the service to the servers in the target server cluster. Therefore, the present embodiment also needs to acquire service status information of each service on each server in the server cluster to be migrated.
Taking game service as an example, a game service line has more than one hundred services and is distributed on each server in a server cluster to be migrated, when offline processing is required to be performed on each server in the server cluster to be migrated to the server in other server clusters, in order to smoothly migrate the service, resource consumption information and service state information of each service on each server in the server cluster to be migrated need to be acquired, and the service state information is used for guiding migration work and whether the service runs after migration.
Step S201, determining an association relationship between services.
The association relationship is a dependency relationship between services, for example, there is a dependency relationship between service 1 and service 2, and there is a dependency relationship between service 2 and service 3, which is only exemplified here, and does not have any limiting effect. The method and the device for determining the association relationship among the services on each server in the server cluster to be migrated are used for guiding service migration work and ensuring that the services with the association relationship can be normally used after migration.
Step S202, determining the residual resource information of each server in the target server cluster.
The target server cluster is a server cluster carrying the migrated services, and the target server cluster is composed of a plurality of servers, in this embodiment, the servers in the target server cluster may already have other services running, and the other services consume resource information of the servers, so before migrating each service on each server in the server cluster to the servers in the target server cluster, the remaining resource information of each server in the target server cluster needs to be determined first to determine to which server in the target server cluster each service should be migrated.
The residual resource information represents the available resource condition of each server in the target server cluster, the total resource information of each server can be determined, and the resource consumption information of the service running on the server can be determined, so that the residual resource information of each server in the target server cluster can be determined according to the total resource information and the resource consumption information.
Step S203, migrating the service item data of the service on each server in the server cluster to be migrated, the call information of other services having an association relationship with the service, and the service status information of each service to the corresponding server in the target server cluster according to the resource consumption information and the remaining resource information, so as to operate the migrated service on each server in the target server cluster according to the service status information.
After acquiring the resource consumption information and the service state information of each service on each server in the server cluster to be migrated, determining the association relation between each service, and determining the residual resource information of each server in the target server cluster, service migration work can be executed, specifically, service item data of the service on each server in the server cluster to be migrated, call information of other services having association relation with the service and service state information of each service are migrated to corresponding servers in the target server cluster according to the resource consumption information and the residual resource information, so that the migrated service can be ensured to be normally used after service migration, and no trouble is caused to user use.
In this embodiment, service item data of a service on each server in a server cluster to be migrated and call information of other services having an association relationship with the service should be migrated to the same server in a target server cluster, so as to ensure that the service can be normally used after migration. Wherein the service item data is data on which the service operates.
Step S204, service testing is carried out on each service migrated to the corresponding server in the target server cluster, and a service testing result is generated so that the user can switch the service according to the service testing result.
After each service on each server in the server cluster to be migrated is migrated to a server in the target server cluster, service testing is required to be performed on each service on a corresponding server in the target server cluster, wherein the service testing is to test whether the migrated service can be normally used or not, and after the testing is completed, a service testing result is generated so that a user can determine whether to perform service switching or not according to the service testing result.
In an alternative embodiment of the present invention, the following method may be used to perform service testing on each service in the corresponding server in the target server cluster: reporting and registering each migrated service on a corresponding server in the target server cluster; and starting the registered service, and performing service test on the started service.
After each service on each server in the server cluster to be migrated is migrated to a server in the target server cluster, each migrated service is reported and registered to a corresponding server in the target server cluster, after the service is reported and registered to the corresponding server in the target server cluster, the registered service is started, and service test is carried out on the started service. By performing service testing on the service, it can be determined whether the service can be used normally, so as to determine whether service switching is performed, that is, whether the service is provided by the server in the target server cluster.
For the service with the association relationship, after the service is reported and registered to the corresponding server in the target server cluster, the service starting can be completed by calling other service calling information according to the association relationship among the services; then, a service test is performed on the initiated service.
Step S205, after the service switching, monitoring whether each server in the server cluster to be migrated receives a service request within a preset time period, and if not, executing step S206.
After service switching is determined according to a service test result, when a user accesses the service again, the service request is sent to a server in the target server cluster, but instead of immediately downloading the server to be migrated, the server in the server cluster to be migrated is subjected to a period of time, whether each server in the server cluster to be migrated receives the service request in a preset period of time is monitored, and under the condition that the service request is not received, the server cluster to be migrated can be subjected to the offline processing, so that normal use of the user can be ensured, the condition that after service switching, the server cluster to be migrated is immediately subjected to the offline processing is avoided, and part of service requests caused by the service requests are sent to the server in the server cluster to be migrated, so that the user cannot normally use the service, and the user experience is poor.
Step S206, performing offline processing on the server cluster to be migrated.
And under the condition that each server in the server cluster to be migrated does not receive a service request in a preset time period, performing offline processing on the server cluster to be migrated.
According to the method provided by the embodiment of the invention, the resource consumption information and the service state information of each service on each server in the server cluster to be migrated are obtained, the association relation between each service is determined, and the residual resource information of each server in the target server cluster is determined; and migrating service item data of services on each server in the server cluster to be migrated, calling information of other services with association relation with the services and service state information of each service to corresponding servers in the target server cluster according to the resource consumption information and the residual resource information, so as to run migrated services on each server in the target server cluster according to the service state information, perform service test on each service migrated to the corresponding servers in the target server cluster, generate service test results, enable a user to perform service switching according to the service test results, and monitor whether each server in the server cluster to be migrated receives a service request within a preset time period after service switching, and if not, perform downlink processing on the server cluster to be migrated. Based on the scheme provided by the invention, the automatic migration of the service between the two clusters is realized, so that the migration accuracy is improved, the defect that the service is unavailable after migration due to the adoption of manual migration service in the prior art is overcome, the normal operation of the service after migration is ensured, a large amount of labor cost is saved, and the time required by service migration is reduced. In addition, during the service migration, the normal use of the service by the user is not influenced, so that the service migration which is not perceived by the user is realized.
