Step 505, the resource tree server returns a node heartbeat response message to the node proxy module;
step 506, the service module registers child nodes to the resource tree server;
in this step, when a service module of a node server is started, a tree node directory corresponding to the node server is obtained by query in a resource tree server, a service sub-node directory is sequentially created under the tree node directory through sub-node registration, and resource service information or configuration information of a service, for example, information such as parameters required by operation of the service module, CPU occupancy parameters, and the like, is written into sub-node attributes of the service sub-node directory.
Step 507, the resource tree server returns the sub-node registration result to the service module;
step 508, the resource tree server requests the management controller to monitor the child nodes and notifies;
step 509, the service module sends a child node heartbeat message to the resource tree server;
step 510, the resource tree server returns a child node heartbeat response message to the service module.
In this step, the tree node and the service child node are both temporary nodes, that is, depending on the heartbeat condition of the node server and the service module, if the node server does not report the node heartbeat message within the preset time, the resource tree server manages the authority of the node server, for example, deletes the tree node directory corresponding to the node server, and notifies the management controller.
The management controller registers with the resource tree server to monitor nodes of each layer under the root node, such as tree nodes and child nodes, so that when the resource tree server adds or deletes the node server, the resource tree server can inform the management controller of the change condition of the node server; when the resource tree server adds or deletes the service sub-nodes belonging to the node server, the management controller can timely know the service node resource information change of the sub-nodes (service modules).

In the embodiment of the present invention, a dotted line indicates that the resource tree server does not receive the child node heartbeat message.
Step 602, the resource tree server sends child node failure information to the management controller;
step 603, in a preset node time period, the resource tree server does not receive the node heartbeat message sent by the first node agent module;
in this step, the resource tree server does not receive the node heartbeat message within the preset node time period, which indicates that the service of the first node to which the first node proxy module belongs is invalid, for example, shutdown or due to a network failure.
Step 604, the resource tree server sends the first node failure information to the management controller;
step 605, the second node agent module sends node heartbeat message to the resource tree server;
in this step, the resource tree server receives the node heartbeat message, and obtains server node resource information of the second node server.
Step 606, the management controller processes based on load balancing principle;
in this step, the management controller switches the service terminated in the first node server to another operating node server according to the obtained server node resource information of each node server and according to the load balancing principle.
In the embodiment of the invention, the management controller determines to switch the service terminated in the first node server to the second node server for operation.
For a detailed description of the load balancing principle, reference may be made to related technical documents, which are not described herein again.
Step 607, the management controller sends service operation information to the second node agent module;
in this step, the service operation information, that is, the node configuration resource information, is used to configure corresponding service resource information for the service terminated in the first node server.
Step 608, the second node agent module sends service operation information to the second node service module to execute service pull-up;
step 609, the second node service module runs the service and sends a child node heartbeat message to the resource tree server.
In this step, the second node service module in the second node server operates the service carried in the service node resource information according to the configuration resource carried in the node configuration resource information.
Therefore, when the service capability of the service needs to be improved, the requirement of service capacity expansion can be met by increasing service resources. When a node server is added, a node agent module in the node server registers to a resource tree server, so that the resource tree server notifies a management controller of server node resource information corresponding to the added node server, the management controller can acquire resource occupation of each node in a current resource tree directory in real time by traversing service resource information of each tree node, and in combination with service resources of each node, based on a load balancing principle, firstly, a node (node server) with tense resource occupation is selected, then, business services running on the node are acquired by reading child nodes of the node, the node agent module of the node is notified to stop the selected business services, and the node agent module of a newly added node is notified to run the business stopped on the node with tense resource occupation, so that the business on the node with tense resource occupation is switched to the node with less resource occupation or the newly added node, and the service resource adjustment of the newly added node is completed, and the availability of the service is improved, so that the service resource management efficiency is improved.
When the service needs to be reduced due to service adjustment, thereby saving server resources, or when the node server fails to work normally due to a fault of the node server, the node agent module in the node server cannot continuously send node heartbeat messages or child node heartbeat messages to the resource tree server, so that the resource tree server takes over corresponding tree nodes and service child nodes, the resource tree server notifies the management controller of the change information of the tree nodes and the service child nodes, the management controller learns the physical resources and the actual occupation situation of the node server by reading the tree node attribute information corresponding to the node server, and learns the stopped service distribution situation on the node server by traversing the service child nodes under the tree node, and selects the nodes with lighter resource occupation in the system based on a load balancing principle, and running the stopped business service on the node proxy module of the node so as to continue the business service.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also encompasses these modifications and variations.
