In the prior art, the main application scenario provides services for short-connection communication, and the services are provided by software in the cluster nodes. Aiming at the use scene of providing encryption application to the outside of a cluster node, because the encryption and decryption service needs to keep the continuous use of key data and the performance of continuous use service, a long connection form is generally needed, and the connection request of a client is insufficient to provide enough load information of the cluster in the specific application scene so as to realize effective balance.
Disclosure of Invention
In order to solve the defects of the prior art, the invention provides a distribution processing method of load balancing in a cluster, which solves the problems that the connection of a client is insufficient to characterize the cluster establishment and load balancing under the condition of the workload of nodes in the cluster, the workload upper limit exists between the main application and the nodes of the cluster, and the network condition, the memory use and the CPU load of the nodes in the cluster cannot effectively characterize the running load of the current node.
The invention solves the technical proposal that the method for distributing and processing the load balance in the cluster comprises the following specific realization processes:
setting load balancing cluster, which is composed of computer server devices and connected to network, wherein the response of the cluster to the request is directly completed by the computer server, the cluster comprises a request receiving unit, a message analyzing unit and a service control unit,
the receiving request unit receives a request after the load balancing process is started;
the message analyzing unit analyzes the received request negatively, judges the type of the request and executes the corresponding branch;
the service control unit is responsible for providing a load balancing mechanism, integrally and jointly providing load balancing service for different equipment, and distributing requests to different load balancing equipment according to equipment states; the service control unit comprises an openalice request module, a heartbeat module, a total Session inquiry module, a total Device inquiry module and a starting password service module,
the workflow of the openalice request module is as follows: request-cluster inquiry-cluster detection-finding out the lowest load node-starting a password service request-returning the request;
the heartbeat module directly replies the request according to the protocol format after receiving the heartbeat inquiry request;
the total Session inquiry module inquires a Session use record table in a Redis database to obtain the total Session of which the current service port is opened;
the total Device inquiry module inquires a Device use record table in the Redis database to obtain the total Device number of the current service opening;
the starting password service module starts/multiplexes the password service after receiving the request; device number: if the Device of one server in the cluster with all service PORTs opened is not more than limit, one PORT is popped out from the Redis PORT pool table, the password service process is started, the parameters are the service PORT IP and the PORT obtained in the last part, and the message is replied according to the protocol after the completion; if the Device of opening all the service ports on one server in the cluster exceeds the limit, inquiring a Session use record table in the Redis database, and finding out the password service process with the least opened Session.
The beneficial effects of the invention are as follows: the distribution processing method for load balancing in the cluster achieves the beneficial effects that the cluster establishment and load balancing under the condition that the client connection is insufficient to represent the workload of the nodes in the cluster are achieved, the workload upper limit exists between the main application and the nodes in the cluster, and the network condition, the memory use and the CPU load of the nodes in the cluster cannot effectively represent the running load condition of the current node.
