[0002] Currently, information systems are often faced with the requirements of high-traffic and elastic transaction services. To meet the above requirements, a solution is usually composed of multiple service nodes and a load balancer: multiple service nodes provide transaction services, and the load balancer distributes transaction services to different service nodes. Among them, the load balancer can be hardware (such as F5) or software (such as LVS). Regardless of the type of load balancer used, it needs to be manually configured so that it can correctly distribute transaction services to service nodes. In addition to providing services for the first time, the load balancer also needs to be manually configured when adding or deleting service nodes. In particular, when using the TUN and DR modes of LVS (Linux Virtual Server), the configuration is more complicated and prone to errors.

[0003] In summary, how to automatically and efficiently implement load balancing configuration is an urgent problem that needs to be solved. Summary of the Invention

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Currently, manual configuration is required for the load balancer. In order to overcome the above problem, the present application provides a cluster-based load balancing configuration solution that can automatically and efficiently implement load balancing configuration.

[0039] See also Figure 1 As shown, the embodiment of the present application discloses a cluster-based load balancing configuration method, which includes:

[0040] Step S11: Start the virtual server nodes and real server nodes in the cluster.

[0041] In the real-time example of this application, the real server node can be represented by the RS (Real Server) node, and the virtual server node can be represented by the LVS (Linux Virtual Server); since the existing technology requires manual configuration for load balancing configuration, the method in this application is proposed; it should be pointed out that load balancing means balancing the load (work task) and distributing it to multiple operating units for operation, so as to complete the work task in a coordinated manner. Load balancing is built on the original network structure. It provides a transparent, cheap and effective method to expand the bandwidth of servers and network devices, enhance network data processing capabilities, increase throughput, and improve network availability and flexibility; LVS (Linux Virtual Server), that is, Linux Virtual Server, LVS is a high-performance four-layer (transport layer TCP / UDP) and seven-layer (application layer) load balancer. It does not directly process requests, but forwards requests to the real server at its back end. Among them, TCP (Transmission Control Protocol) is the transmission control protocol, and UDP (User Datagram Protocol) is the user datagram protocol. Specifically, the LVS working mode is divided into NAT mode, TUN mode, and DR mode. Before introducing the LVS operating mode, let's first discuss several IP (Internet Protocol) protocols related to LVS: VIP (Virtual IP), the IP address of the network card on the LVS server that receives external network packets. DIP (Director IP), the IP address of the network card on the LVS server that forwards packets to the real server. RIP (Real IP), the IP address of the real server (often referred to as RS) that receives packets forwarded by the Director in the figure, i.e., the IP address of the server providing the service. CIP (Client IP), the IP address of the client.

[0042] In an embodiment of the present application, the virtual server node and the real server node in the cluster both include a notification service and a tool for performing load balancing configuration and connecting to the notification service, and the tool is an LBConf component. In addition, the virtual server node also includes an LVS component and a load balancing policy template. Specifically, the notification service is responsible for establishing a message notification mechanism within the cluster, and registering or publishing the node information of the node where the notification service is located to the cluster. The LBConf component is used to connect to the notification service of the node where it is located, receive the node information of all nodes in the cluster through the notification service, and perform load balancing configuration on the virtual server node based on the node information, and perform network configuration on the real server node. In addition, the real server nodes in the cluster run the notification service and LBConf components, and provide real business transaction services; the virtual server node exposes the business IP address to the outside, and the LVS component distributes the received business load to the real server node.

[0043] In an embodiment of the present application, after starting the virtual server node and the real server node in the cluster, the real server node is controlled to register its own first node information in the cluster and the virtual server node is controlled to register its own second node information in the cluster, and then the real server node and the virtual server node are controlled to obtain all the first node information and the second node information from the cluster. Specifically, after starting the virtual server node and the real server node in the cluster, the real server node is controlled to start its own notification service, and then register its own first node information in the cluster through the notification service, and the virtual server node is controlled to start its own notification service, and then register its own second node information in the cluster through the notification service. Specifically, the real server node and the virtual server node obtain all the first node information and the second node information from the cluster in the form of a target node list.

[0044] It should be pointed out that the first node information includes the IP address information, type information and specification information of the real server node, the type information indicates whether the node is a real server node or a virtual server node, and the specification information is the business processing capability of the real server node (generally represented by the CPU (central processing unit) computing power); the second node information includes the IP address information, VIP address information, type information and specification information of the virtual server node, the type information indicates whether the node is a real server node or a virtual server node, and the specification information is the business processing capability of the virtual server node (generally represented by the CPU computing power).

[0045] It should be noted that when starting a node in the cluster, the node in the cluster needs to determine whether it is a real server node or a virtual server node to determine the operation to be performed.

[0046] Step S12: When the virtual server node is started, each virtual server node is controlled to automatically add the first node information of each real server node in its own load service, and set a corresponding weight for each first node information, so that the virtual server node sends the business load in the load service to the corresponding real server node based on the weight.

[0047] In the embodiment of the present application, when the virtual server node is started, each virtual server node is first controlled to automatically configure the LVS component according to the load balancing policy template saved by itself, and each virtual server node is controlled to automatically create the corresponding load service for its own service port according to the load balancing policy template saved by itself, and add the load service to the corresponding service port. It should be noted that each service port has a corresponding balancing policy.

[0048] It should be noted that the balancing strategy includes but is not limited to a hash algorithm, a round-robin algorithm, and the like.

[0049] In an embodiment of the present application, the first node information of all the real server nodes is filtered out from the node information of all nodes obtained from the virtual server node, and each virtual server node is controlled to automatically add the first node information of each real server node to its own load service, and the specification information in each first node information is used to set a corresponding weight for each first node information, so that the virtual server node uses the LVS component and sends the business load in the load service to the corresponding real server node based on the weight. It should be noted that the LVS component is configured according to the load balancing policy template.

[0050] It should be noted that the node information of all nodes can be saved in list form, and the first node information of all real server nodes can be filtered out from the node information of all nodes obtained from the virtual server node, which can be the process of filtering out the real server node list from the list of all nodes.

[0051] Step S13: When the real server node is started, each real server node is controlled to automatically add the VIP address information in the second node information of the virtual server node in its own preset interface, so that the real server node receives and processes the business load sent by the corresponding virtual server node based on the VIP address information in the second node information; wherein, the VIP is a virtual IP.

[0052] In an embodiment of the present application, when the real server node is started, the second node information of all the virtual server nodes is filtered out from the node information of all nodes obtained from the real server node, and the VIP address information is filtered out from the second node information, and then each of the real server nodes is controlled to automatically add the VIP address information in the second node information of the virtual server node to its own preset interface, so that the real server node receives and processes the business load sent by the corresponding virtual server node based on the VIP address information in the second node information.

[0053] It should be noted that the node information of all nodes can be saved in list form, and the first node information of all virtual server nodes can be filtered out from the node information of all nodes obtained from the real server node, which can be the virtual server node list filtered out from the list of all nodes.

[0054] It can be seen that the present application starts the virtual server nodes and real server nodes in the cluster; when the virtual server node is started, each virtual server node is controlled to automatically add the first node information of each real server node in its own load service, and a corresponding weight is set for each first node information, so that the virtual server node sends the business load in the load service to the corresponding real server node based on the weight; when the real server node is started, each real server node is controlled to automatically add the VIP address information in the second node information of the virtual server node in its own preset interface, so that the real server node receives and processes the business load sent by the corresponding virtual server node based on the VIP address information in the second node information; wherein the VIP is a virtual IP. It can be seen that the present application controls each virtual server node to automatically add the first node information of each real server node in its own load service through the notification service and LBConf components, and sets a corresponding weight for each first node information, and controls each real server node to automatically add the VIP address information in the second node information of the virtual server node in its own preset interface. In this way, the load balancing configuration within the cluster is automatically and efficiently completed.

[0055] See also Figure 2 As shown, the embodiment of the present application discloses a specific cluster-based load balancing configuration method, which includes:

[0056] Step S21: Start the virtual server nodes and real server nodes in the cluster.

[0057] For a more specific processing procedure of step S21 , reference may be made to the corresponding contents disclosed in the aforementioned embodiments, which will not be described in detail here.

[0058] Step S22: When the virtual server node is started, each virtual server node is controlled to automatically add the first node information of each real server node in its own load service, and set a corresponding weight for each first node information, so that the virtual server node sends the business load in the load service to the corresponding real server node based on the weight.

[0059] For a more specific processing procedure of step S22, reference may be made to the corresponding contents disclosed in the aforementioned embodiments, which will not be described in detail here.

[0060] Step S23: When the real server node is started, each real server node is controlled to automatically add the VIP address information in the second node information of the virtual server node in its own preset interface, so that the real server node receives and processes the business load sent by the corresponding virtual server node based on the VIP address information in the second node information; wherein, the VIP is a virtual IP.

[0061] For a more specific processing procedure of step S23, reference may be made to the corresponding contents disclosed in the aforementioned embodiment, which will not be described in detail here.

[0062] Step S24: When it is detected that the node status of the real server node in the cluster changes, the virtual server node is controlled to automatically adjust the first node information in its own load service; when it is detected that the node status of the virtual server node in the cluster changes, the real server node is controlled to automatically adjust the VIP address information in the second node information in its own preset interface.

[0063] In an embodiment of the present application, when the node status of the virtual server node and the real server node in the cluster changes, it is necessary to adjust the completed load balancing settings, that is, to control the virtual server node to automatically adjust the first node information in its own load service and control the real server node to automatically adjust the VIP address information in the second node information in its own preset interface. Specifically, when it is detected that a new or re-online real server node appears in the cluster, a first notification message is sent to all other server nodes, and the virtual server node is controlled to automatically add the first node information of the real server node to its own load service based on the first notification message, and set the corresponding weight for the first node information; when it is detected that the real server node in the cluster is offline, a second notification message is sent to all other server nodes, and the virtual server node is controlled to automatically delete the first node information of the real server node in the load service based on the second notification message. When it is detected that a new virtual server node appears in the cluster or is brought back online, a third notification message is sent to all other server nodes, and the real server node is controlled to automatically add the VIP address information in the second node information of the virtual server node to its own preset interface based on the third notification message; when it is detected that the virtual server node in the cluster is offline, a fourth notification message is sent to all other server nodes, and the real server node is controlled to automatically delete the VIP address information in the second node information of the virtual server node in its own preset interface based on the fourth notification message.

[0064] It should be pointed out that when a new or re-online real server node is detected in the cluster, it is also necessary to start and register the first node information of the real server node to the cluster through the notification service of the real server node, and obtain the first node information of other real server nodes in the cluster and the second node information of the virtual server node from the cluster, and then perform step S23 to control each real server node to automatically add the VIP address information in the second node information of the virtual server node to its own preset interface, so that the real server node receives and processes the business load sent by the corresponding virtual server node based on the VIP address information in the second node information.

[0065] It should be pointed out that when a new or re-online virtual server node is detected in the cluster, it is also necessary to start and register the second node information of the virtual server node with the cluster through the notification service of the virtual server node, and obtain the first node information of other real server nodes in the cluster from the cluster, and then perform step S24 to control each virtual server node to automatically add the first node information of each real server node in its own load service, and set a corresponding weight for each first node information, so that the virtual server node sends the business load in the load service to the corresponding real server node based on the weight.

[0066] It can be seen that the virtual server nodes and real server nodes in the cluster are started; when the virtual server node is started, each virtual server node is controlled to automatically add the first node information of each real server node in its own load service, and a corresponding weight is set for each first node information, so that the virtual server node sends the business load in the load service to the corresponding real server node based on the weight; when the real server node is started, each real server node is controlled to automatically add the VIP address information in the second node information of the virtual server node in its own preset interface, so that the real server node receives and processes the business load sent by the corresponding virtual server node based on the VIP address information in the second node information; wherein, the VIP is a virtual IP; when it is detected that the node status of the real server node in the cluster changes, the virtual server node is controlled to automatically adjust the first node information in its own load service; when it is detected that the node status of the virtual server node in the cluster changes, the real server node is controlled to automatically adjust the VIP address information in the second node information in its own preset interface. It can be seen that this application controls each virtual server node through the notification service and LBConf component to automatically add the first node information of each real server node to its own load service, and sets a corresponding weight for each first node information, and controls each real server node to automatically add the VIP address information in the second node information of the virtual server node to its own preset interface, thereby automatically and efficiently completing the load balancing configuration within the cluster. When adding or deleting real server nodes and virtual server nodes within the cluster, this application controls each node to automatically update the load balancing configuration, which is more convenient and quick, and makes this solution elastic, efficient and highly available.

[0067] See also Figure 3As shown, this is a schematic diagram of a load balancing configuration structure provided by the present application, which includes a client, two virtual server nodes (LVS nodes) and three real server nodes (RS nodes). Each LVS node and each RS node has a notification service and an LBConf component. Each LVS node also has a policy template, an LVS component and multiple load services. Each RS node also includes a loopback (Lo) / tunl0 interface and multiple network services. When performing business processing, the client first initiates a business request and sends the business request to the load service of the corresponding service port in any virtual server node. Then, according to the weight and balancing strategy, the business load is forwarded to the corresponding network service in the corresponding real server node, and processed in the real server node. The business processing result is then returned to the client. It should be pointed out that there is a master node in the real server node, which controls the notification of other nodes to perform node registration, obtain the node list and obtain update information (i.e., notification information) after the node status changes.

[0069] A node startup module 11 is used to start the virtual server nodes and real server nodes in the cluster;

[0070] a virtual server node configuration module 12, configured to control each virtual server node to automatically add the first node information of each real server node to its own load service when the virtual server node is started, and to set a corresponding weight for each first node information, so that the virtual server node sends the business load in the load service to the corresponding real server node based on the weight;

[0071] The real server node configuration module 13 is used to control each real server node to automatically add the VIP address information in the second node information of the virtual server node to its own preset interface when the real server node is started, so that the real server node receives and processes the business load sent by the corresponding virtual server node based on the VIP address information in the second node information; wherein, the VIP is a virtual IP.

[0072] Among them, for more specific working processes of the above modules, please refer to the corresponding contents disclosed in the aforementioned embodiments, which will not be repeated here.

[0073] It can be seen that the present application starts the virtual server nodes and real server nodes in the cluster; when the virtual server node is started, each virtual server node is controlled to automatically add the first node information of each real server node in its own load service, and set a corresponding weight for each first node information, so that the virtual server node sends the business load in the load service to the corresponding real server node based on the weight; when the real server node is started, each real server node is controlled to automatically add the VIP address information in the second node information of the virtual server node in its own preset interface, so that the real server node receives and processes the business load sent by the corresponding virtual server node based on the VIP address information in the second node information; wherein the VIP is a virtual IP. It can be seen that the present application controls each virtual server node to automatically add the first node information of each real server node in its own load service, and set a corresponding weight for each first node information, and controls each real server node to automatically add the VIP address information in the second node information of the virtual server node in its own preset interface. In this way, the load balancing configuration within the cluster is completed automatically and efficiently.
