Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
The invention is operational with numerous general purpose or special purpose computing device environments or configurations. For example: personal computers, server computers, hand-held or portable devices, tablet-type devices, multi-processor apparatus, distributed computing environments that include any of the above devices or equipment, and the like.
Referring to fig. 1, a flowchart of a method for controlling a method according to an embodiment of the present invention is shown, where the method is applied to a server cluster, where the server cluster includes a plurality of servers; the execution main body of the method can be a processor applied to a client side, and can also be a processor applied to a server side; the method may comprise the steps of:
step S101: and monitoring the load of a target server in real time, wherein the target server is any one server in the server cluster.
The method provided by the invention is used for monitoring the load of any one server in the server cluster when the server is in a working state.
Specifically, in this embodiment, the load of the target server may be monitored by monitoring the data traffic of the data interaction performed on the target server.
Step S102: when the load of the target server exceeds a first preset load threshold value corresponding to the target server, distributing an auxiliary server for the target server; and setting a load balancing module, wherein the load balancing module corresponds to the target server and the auxiliary server respectively.
In the server cluster, any one server has its own load upper limit, and the load upper limits of the servers may be the same or different. In this embodiment, the upper limit of the load of the server is used as the first preset load threshold, and when the processing capacity of the target server, such as the data interaction amount, exceeds the upper limit of the load of the target server, the auxiliary server is allocated to the target server, and a load balancing module is set for the target server and the auxiliary server to allocate the load.
It should be noted that the auxiliary server corresponding to the target server may be implemented by one server, or may be implemented by a plurality of servers, and the target server and the auxiliary server corresponding to the target server correspond to one load balancing module.
When the load balancing module is set in this embodiment, the method specifically includes: and configuring data such as IP addresses, port addresses and the like of the auxiliary server and the target server.
Step S103: and the load balancing module is used for distributing the load of the target server and controlling the target server and the auxiliary server to jointly process the load of the target server.
That is, the load balancing module redistributes the load originally directed to the target server and distributes the load to the target server and the auxiliary server corresponding to the target server for engineering load bearing, so that a part of the load on the target server is borne by the auxiliary server, and the load burden on the target server is further reduced.
As can be seen from the foregoing solutions, in a control method provided in an embodiment of the present invention, the method is applied to a server cluster, where the server cluster includes a plurality of servers; regarding any server as a target server, monitoring the load of the target server in real time; when the load of the target server exceeds a first preset load threshold value corresponding to the target server, distributing an auxiliary server for the target server; setting a load balancing module, wherein the load balancing module corresponds to the target server and the auxiliary server respectively; and the load balancing module is used for distributing the load of the target server and controlling the target server and the auxiliary server to jointly process the load of the target server. In the embodiment, the load of the original target server is shared by adding the auxiliary server, so that the problems of overload operation of a host, low processing speed and reduction of user access efficiency are solved.
As shown in fig. 2, which is another flowchart of the embodiment of the present invention, in this embodiment, on the basis of fig. 1, after the step S103, the method may further include the following steps:
step S104: and when the load of the target server is monitored to be lower than a second preset load threshold value, closing the load balancing module, and closing the auxiliary server after the load balancing module is closed.
The second preset load threshold may be set according to a user requirement, for example, a half or one third of a load value of the smooth operation of the target server is set as the second preset load threshold, and when the real-time load of the target server is lower than the second preset load threshold, it is indicated that the target server can easily bear the current load or can easily bear a load twice or three times the current load, and therefore, the present embodiment may stop the load balancing scheme, that is, close the load balancing module and the auxiliary server.
In addition, in this embodiment, after the auxiliary server is turned off, the load allocated to the auxiliary server is re-sent to the target server for processing, that is, all the loads on the auxiliary server and the target server are assumed by the target server, and as can be seen from the foregoing, the real-time load of the target server is lower than the second preset load threshold, and accordingly, the overall load is lower than the load value of the target server in the unobstructed operation, so that the target server can operate in the unobstructed manner while assuming all the loads.
In a specific implementation, when allocating an auxiliary server to the target server, this embodiment may be implemented by the following steps, as shown in fig. 3:
step S201: and searching for an idle server in the server cluster according to the current load of the target server and the first preset load threshold value.
Wherein, the idle server can be understood as: no task is done running the server with 0 load.
Specifically, in this embodiment, the number N of auxiliary servers required under the condition that the target server is ensured to be able to run smoothly (that is, the real-time load of the target server is the first preset load threshold) may be determined by analyzing the current load, and then N idle servers are searched in the server cluster, where N is a positive integer greater than or equal to 1.
Step S20: 2: and associating the searched idle server with the target server to serve as an auxiliary server of the target server.
Specifically, in this embodiment, the association between the idle server and the target server may be realized by setting a mapping relationship of an IP address or a mapping relationship of an ID name between the idle server and the target server.
In a specific implementation, when the load balancing module is used to allocate the load of the target server, the embodiment may specifically be implemented by the following steps, as shown in fig. 4:
step S301: and updating a network address translation Nat table, and transferring the port address of the target server to the load balancing module.
For example, in the updated Nat table in this embodiment, the path address of the data interaction data is: and the load balancing module receives the data through a port address and forwards the data to the target server or the auxiliary server.
Step S302: and indicating the load balancing module to distribute the load received by the port address to the target server and the auxiliary server according to the load capacity of the target server and the auxiliary server respectively.
For example, when there are two auxiliary servers, the load balancing module divides the load into three parts, each part of load corresponds to the load capacity of the target server and the two auxiliary servers, and then distributes the loads to the corresponding servers.
In a specific implementation, the auxiliary server may be associated with the client corresponding to the target server, so that the auxiliary server and the target server can both feed back the loads processed by the auxiliary server and the target server to the client.
It should be noted that the load in this embodiment may be understood as a service request load or a non-service request load of a user. When the load is the service request load, in this embodiment, the load balancing module allocates the load to the target server and the auxiliary server, and the target server and the auxiliary server share the load; and when the load sent to the target server is a non-service request load, the load balancing module directly distributes the non-service request load to the target server, and the auxiliary server does not process the non-service request load.
Fig. 5 is a diagram illustrating an embodiment of the present invention. In this embodiment, a monitoring module is used to monitor a VM (target server) of a user, and the monitoring module mainly includes a load condition and a Service port that the user mainly accesses, when the user accesses a Service provided by the VM through an EIP of the Service, a Nat module receives a user request and then forwards the user request to a corresponding VM, and when the monitoring module finds that the VM load is higher, the Nat module reports the VM request to a management module, and the management module starts a new VM2 (auxiliary server) for the user; at the same time, the management module starts a load balancing module for the user, and performs corresponding configuration, such as configuring the IP and port of VM1 and VM2, and finally the management module needs to update the Nat table (the Nat module needs to be modified accordingly), as follows:
EIP->VM1->if Port->LB
and Session table:
EIP:Port->LB:Port->VM1:Port
EIP:Port->LB:Port->VM2:Port
thus, network packets destined for the VM1 service port are caused to be forwarded to the load balancing module; meanwhile, network packets returned by the VM1 and the VM2 can be correctly returned to the client, and at the moment, the VM2 is invisible to the client.
Then, when a new user request comes, the Nat module forwards the new user request to the load balancing module through the rule EIP- > VM1- > LB, and the load balancing module forwards the new user request to the VM1 and the VM2 according to a certain load balancing strategy; non-service requests for the user, such as SSH, PING, may also be sent directly to VM1 without affecting the user's use.
When the monitoring module finds that the load of the VM is reduced, reporting the load to the management module;
the management module determines whether the VM2 can be shut down, and if so, updates the Nat table so that network packets accessing the EIP are directly forwarded to the VM1, and simultaneously shuts down the load balancing module and finally shuts down the VM 2.

a closing unit 403, configured to close the load balancing module when it is monitored that the load of the target server is lower than a second preset load threshold, and close the auxiliary server after the load balancing module is closed.
