Description

Technical Field

[0001] The present invention relates to the field of server clusters, and particularly to a server cluster monitoring method, a computing device, and a storage medium. Background Art

[0002] With the development of cloud computing technology, container technology is used more and more widely. Many enterprises have started to use container technology to deploy applications to improve resource utilization and deployment efficiency. In order to better use container technology to provide services, more and more enterprises provide services externally by deploying server clusters. Existing server clusters usually include a master-slave architecture mode and multiple data nodes. When the master node in the server cluster fails to provide services, a slave node is selected from other slave nodes in the server cluster as the master node so that the server cluster can provide services normally.

[0003] However, in the prior art, when the old master node in the server cluster fails and the data generated during service provision is not backed up to the slave node in time, and the slave node becomes the master node, this part of the data will be lost. Moreover, when the master node changes, the new master node cannot automatically start providing services and requires manual reconfiguration; during the process of manual fault handling, the server cluster pauses to provide services, resulting in business suspension.

[0004] Therefore, a new server cluster monitoring method is needed. Summary of the Invention

[0005] Therefore, the present invention provides a server cluster monitoring method in an attempt to solve or at least alleviate the problems mentioned above.

[0006] According to one aspect of the present invention, there is provided a server cluster monitoring method suitable for execution in a monitoring server. The monitoring server monitors a server cluster, and the server cluster includes a master node and multiple slave nodes. The method includes the steps of: obtaining and storing first cluster information of the server cluster, where the first cluster information includes first master node information; after a predetermined time, obtaining second cluster information of the server cluster, where the second cluster information includes second master node information, and comparing the second cluster information with the first cluster to determine whether the second master node information in the second cluster information is the same as the first master node information in the first cluster information; if the second master node information is different from the first master node information, constructing a second service interface according to the second master node information so that the second master node of the server cluster provides services to users according to the second service interface.

Constructing a second service interface according to the second master node information includes the steps of: constructing a second service interface according to the IP address of the second master node, so that when a user sends a service request to the server cluster through domain name information, the server cluster calls the second service interface to determine the IP address of the second master node, and sends the service request to the second master node according to the IP address of the second master node.

[0009] Optionally, in the method according to the present invention, it further includes the step of storing the second cluster information to determine whether the server cluster has changed.

[0010] Optionally, in the method according to the present invention, the first cluster information further includes first slave node information, and the second cluster information further includes second slave node information. The method further includes the steps of: if the second master node information is the same as the first master node information, determining whether the second slave node information in the second cluster information is the same as the first slave node information in the first cluster information; if the second slave node information is different from the first slave node information, storing the second cluster information to determine whether the server cluster has changed.

[0011] Optionally, in the method according to the present invention, if the second slave node information is different from the first slave node information, storing the second cluster information includes the steps of: determining whether there are offline slave nodes according to the second slave node information and the first slave node information; if there are offline slave nodes, determining whether the offline slave nodes have failed; if the offline slave nodes have failed, storing the second cluster information.

[0012] Optionally, in the method according to the present invention, after receiving a service request, the master node in the server cluster is adapted to send the data in the service request to the slave nodes, so that the slave nodes send confirmation information and store the data. The master node is further adapted to store the data after receiving confirmation information from more than a predetermined number of slave nodes.

[0013] Optionally, in the method according to the present invention, the predetermined number is half of the number of slave nodes in the server cluster.

[0014] Optionally, in the method according to the present invention, when the first master node fails, one of the slave nodes in the server cluster serves as the master node.

[0015] According to another aspect of the present invention, there is provided a computing device, including: one or more processors; a memory; and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, and the one or more programs include those for executing the server cluster monitoring method according to the present invention.

[0016] According to another aspect of the present invention, there is provided a computer-readable storage medium storing one or more programs, the one or more programs including instructions which, when executed by a computing device, cause the computing device to execute the server cluster monitoring method according to the present invention.

[0017] In the server cluster monitoring method of the present invention, the monitoring server monitors the cluster information of the server cluster, and determines whether the master node in the server cluster fails by comparing whether the cluster information at two different time nodes is the same.

As Figure 1 shown, the monitoring server 120 monitors the server cluster 110. The server cluster 110 includes a master node 111 and slave nodes 112-117. In the server cluster 110, the master node 111 provides services to users through a service interface.

As Figure 2 shown, in a basic configuration 202, the computing device 200 typically includes a system memory 206 and one or more processors 204. A memory bus 208 can be used for communication between the processor 204 and the system memory 206.

The processor 204 can include one or more levels of cache such as a level 1 cache 210 and a level 2 cache 212, a processor core 214, and registers 216. An exemplary processor core 214 can include an arithmetic logic unit (ALU), a floating point unit (FPU), a digital signal processing core (DSP core), or any combination thereof. An exemplary memory controller 218 can be used with the processor 204, or in some implementations, the memory controller 218 can be an internal part of the processor 204.

[0029] Depending on the desired configuration, system memory 206 can be any type of memory, including but not limited to: volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.), or any combination thereof. System memory 206 can include an operating system 220, one or more programs 222, and program data 228. In some embodiments, program 222 can be arranged to execute instructions 223 of method 300 according to the present invention by one or more processors 204 on the operating system using program data 228.

[0030] Computing device 200 may also include a storage interface bus 234.

At least a portion of operating system 220, program 222, and data 224 can be stored on removable storage 236 and / or non-removable storage 238, and when computing device 200 is powered on or program 222 is to be executed, it is loaded into system memory 206 via storage interface bus 234 and executed by one or more processors 204.

[0031] Computing device 200 may also include an interface bus 240 that facilitates communication from various interface devices (e.g., output device 242, peripheral interface 244, and communication device 246) to basic configuration 202 via bus / interface controller 230. Example output device 242 includes a graphics processing unit 248 and an audio processing unit 250.

Example communication device 246 can include a network controller 260, which can be arranged to communicate with one or more other computing devices 200 via one or more communication ports 264 through a network communication link.

[0032] A network communication link can be an example of a communication medium. A communication medium can generally embody computer-readable instructions, data structures, program modules in a modulated data signal such as a carrier wave or other transmission mechanism, and can include any information delivery medium. A "modulated data signal" can be a signal in which one or more of its data sets or its changes can encode information in the signal. As a non-limiting example, a communication medium can include wired media such as a wired network or a dedicated line network, and various wireless media such as sound, radio frequency (RF), microwave, infrared (IR), or other wireless media. The term computer-readable medium used herein can include both storage media and communication media.

[0033] In the computing device 200 according to the present invention, the program 222 includes multiple program instructions of the server cluster monitoring method 300, and these program instructions can instruct the processor 204 to execute some steps in the server cluster monitoring method 300 running in the computing device 200 of the present invention, so that each part in the computing device 200 monitors the server cluster by executing the server cluster monitoring method 300 of the present invention.

[0034] The computing device 200 can be implemented as a server, such as a file server 240, a database 250, a server, an application server, etc. These electronic devices can be such as a personal digital assistant (PDA), a wireless network browsing device, an application-specific device, or a hybrid device that can include any of the above functions. It can be implemented as a personal computer including a desktop computer and a laptop computer configuration. Also, in some embodiments, the computing device 200 is configured to execute the server cluster monitoring method 300.

[0035] Figure 3 A flowchart of the server cluster monitoring method 300 according to an exemplary embodiment of the present invention is shown. The server cluster monitoring method 300 in the present invention is adapted to be executed in the monitoring server 120. First, step S310 is executed to obtain and store the first cluster information of the server cluster, and the first cluster information includes the first master node information and the first slave node information.

[0036] According to as Figure 1The schematic diagram of the current monitoring server monitoring the server cluster is shown. The monitoring server 120 monitors the server cluster 110, and the server cluster 110 includes a master node 111 and slave nodes 112 to 117. The first cluster information is the cluster information of the server cluster when the monitoring server obtains the first cluster information. The monitoring server can obtain the cluster information of the server cluster at any time. At this time, the cluster information of the server cluster is the first cluster information, its master node is the first master node, and the information of the first master node is the first master node information, including the IP address of the master node. The other nodes in the server node are slave nodes, and the information of these slave nodes is the first slave node information. The first slave node information includes the slave node information of multiple slave nodes in the server node. The slave node information of each slave node includes the IP address of the slave node.

[0037] According to an embodiment of the present invention, as Figure 1 shown, the cluster information of the server cluster 110 is the first cluster information, where the first master node is the master node 111. The first cluster information includes the first master node information and the first slave node information. The first master node information includes the IP address of the master node 111. The first slave node information includes the IP addresses of the slave nodes 112 to 117.

[0038] Subsequently, step S320 is executed. After a predetermined time, the second cluster information of the server cluster is obtained. The second cluster information includes the second master node information, and the second cluster information is compared with the first cluster to determine whether the second master node information of the second cluster information is the same as the first master node information of the first cluster information.

[0039] According to an embodiment of the present invention, after the monitoring server obtains the first node information, after a predetermined time, the second cluster information is obtained. The second cluster information is the cluster information of the server cluster when the monitoring server obtains the second cluster information. At this time, the cluster information of the server cluster is the second cluster information, its master node is the second master node, and the information of the second master node is the second master node information, including the IP address of the master node. The other nodes in the server node are slave nodes, and the information of these slave nodes is the second slave node information. The second slave node information includes the slave node information of multiple slave nodes in the server node. The slave node information of each slave node includes the IP address of the slave node. The present invention does not display the predetermined time, and the predetermined time can be set according to specific business needs, such as being set to 5 seconds.

[0040] If within the predetermined time, neither the master node nor the slave nodes in the server cluster have failed and the first cluster information is the same as the second cluster information, then the second cluster information is stored, and the training information of the server cluster is obtained again after the predetermined time, continuously monitoring the server cluster to determine whether there are any failed nodes in the server cluster.

[0041] According to one embodiment of the present invention, when the first master node fails, a slave node in the server cluster provides services as the master node. At this time, the new master node and other slave nodes constitute a new server cluster. The cluster information of this new server cluster is the second cluster information, wherein the new master node is the second master node, its node information is the second master node information, and the information of the remaining slave nodes is the second slave node information. The monitoring server obtains the second cluster information of the server cluster, and determines whether the second cluster information is the same as the first cluster information, so as to determine whether there is a node failure in the server cluster and exit the server cluster.

[0042] When the monitoring server determines whether the second cluster information is the same as the first cluster information, it first determines whether the second master node information in the second cluster information is the same as the first master node information in the first cluster information. If not, it determines that the first master node has a fault.

[0043] If the second master node information is the same as the first master node information, then determine whether the second slave node information in the second node information is the same as the first cluster node information in the first cluster information. If they are not the same, it can be determined that a new slave node has joined the server cluster, or the original slave node has failed and exited the server cluster.

[0044] Figure 4 A schematic diagram of a monitoring server acquiring second cluster information according to an exemplary embodiment of the present invention is shown. Within a predetermined time, a master node 111 in a server cluster 110 fails, and a slave node 112 becomes a master node 412, and forms a new server cluster 410 with other slave nodes 113 to 117. The cluster information of the server cluster 410 is the second cluster information, wherein the second master node is the master node 412. The second cluster information includes the second master node information and the second slave node information. The second master node information includes the IP address of the master node 412. The second slave node information includes the IP addresses of the slave nodes 113 to 117.

[0045] The monitoring server compares the second cluster information with the first cluster information, and first determines whether the second master node information is the same as the first master node information.

[0046] Figure 5 The figure shows a schematic diagram of the recovery time objective according to an exemplary embodiment of the present invention. The recovery time objective (RTO) refers to the time required for an information system to recover from a disaster state to an operational state, and is used to measure the business recovery capability of the disaster recovery system. Figure 5As shown, before time T0, the server cluster is running normally. A failure occurs at time T1, and the server cluster doesn't resume normal operation until time T2. The time period from T1 to T2 is the system interruption time, i.e., RTO. To minimize RTO, in the present invention, the server cluster is continuously monitored to obtain the cluster information of the server cluster, and the cluster information of two adjacent times is fully compared. When it is determined that the primary node fails, a service interface is constructed for the new primary node according to its primary node information so that it can quickly go online to provide services.

[0047] Subsequently, step S330 is executed. If the second primary node information is different from the first primary node information, a second service interface is constructed according to the second primary node information so that the second primary node of the server cluster can provide services to users according to the second service interface.

[0048] According to an embodiment of the present invention, when the IP address of the primary node 111 is changed to the IP address of the primary node 412, the monitoring server determines that the second primary node information is different from the first primary node information.

[0049] Before the monitoring server constructs a second server interface according to the second primary node information, it also determines whether the first primary node 111 of the server cluster fails. If the first primary node 111 fails, the first service interface constructed according to the first primary node information is deactivated.

[0050] The purpose of the monitoring server to determine whether the first primary node 111 fails is to check the first primary node 111 again to ensure that it is not a misoperation caused by network jitter and improve system reliability. According to an embodiment of the present invention, the probability of misoperation of the server cluster is 1%, and the probability of misjudgment of the monitoring server is 1%. Then the reliability of the system is 99.99%.

[0051] The server cluster provides services to users according to the domain name information. When a user needs the server cluster to provide services, the user needs to access the server cluster through the domain name information, and the domain name information includes the domain name of the server cluster. When constructing a second service interface according to the second primary node information, the second service interface is constructed according to the IP address of the second primary node so that when the user sends a service request to the server cluster through the domain name information, the server cluster calls the second service interface to determine the IP address of the second primary node and sends the service request to the second primary node according to the IP address of the second primary node.

[0052] According to an embodiment of the present invention, in the server cluster 110, the first master node is the master node 111, and a first service interface is constructed according to the first master node information, where the first master node information includes the IP address of the master node 111. When a user accesses the server cluster through domain name information, a service request is sent to the server cluster. The server cluster determines, according to the first service interface, that the master node for receiving and processing the service request is the first master node, and the first master node, that is, the master node 111, receives the service request through the first server interface and processes it. When the first master node fails and goes offline, the first service interface constructed according to the first master node information cannot be used continuously. Therefore, it is necessary to construct a second service interface.

[0053] In the server cluster 410, the second master node is the master node 412, and a second service interface is constructed according to the second master node information. When a user accesses the server cluster through domain name information, a service request is sent to the server cluster. The server cluster determines, according to the second service interface, that the master node for receiving and processing the service request is the second master node, and the second master node, that is, the master node 412, receives the service request through the second server interface and processes it.

[0054] According to an embodiment of the present invention, after the server cluster constructs the second service interface, the second cluster information is stored to facilitate subsequent determination of whether the server cluster has changed.

[0055] According to an embodiment of the present invention, if the second master node information is the same as the first master node information, it is determined whether the second slave node information of the second cluster information is the same as the first slave node information of the first cluster information. If the second slave node information is different from the first slave node information, the second cluster information is stored to facilitate determination of whether the server cluster has changed.

[0056] When it is determined that the second slave node information is different from the first slave node information, it is determined whether there is a slave node that has gone offline according to the second slave node information and the first slave node information. Specifically, it is determined whether there is an IP address that only appears in the first slave node information. If so, it is determined that the slave node to which the IP address belongs is the offline slave node.

[0057] Next, if there is an offline slave node, it is determined whether the offline slave node has failed, and the offline of the slave node is determined again to prevent misoperations caused by network jitter and improve system reliability. Finally, if the offline slave node has failed, the second cluster information is stored.

[0058] Figure 6A schematic diagram of a recovery point objective according to an exemplary embodiment of the present invention is shown. The recovery point objective (RPO) refers to the maximum amount of data loss allowed in a business system during a disaster and is used to measure the data redundancy backup ability of a disaster recovery system. As Figure 6 shown, before time T0, the data is valid. Time T0 is the last time when the data is valid, and the data has been backed up before time T0. A failure occurs at time T1 after time T0, resulting in data loss during the time period from T0 to T1 when the data was not backed up.

[0059] To minimize the RPO, in the present invention, the server cluster adopts a method of data backup confirmation. Specifically: the master node in the server cluster is adapted to send the data in the service request to the slave nodes after receiving the service request, so that the slave nodes send confirmation information and store the data. The master node is also adapted to store the data after receiving confirmation information from more than a predetermined number of slave nodes. Wherein, the predetermined number is half of the number of slave nodes in the server cluster.

[0060] To enable the slave nodes of the server to fully back up the data of the master node, the master node first allows the slave nodes to back up the data before storing and processing the data. After receiving the data and storing it, the slave nodes send confirmation information to the master node. After more than half of the slave nodes in the server cluster have backed up the data, the master node then stores and processes the data, thus ensuring that no data is lost when the master node fails.

[0061] In the server cluster monitoring method of the present invention, the monitoring server monitors the cluster information of the server cluster, and determines whether the master node in the server cluster fails by comparing whether the cluster information at two different time nodes is the same. If the master node fails, a service interface is constructed for the new master node, so that the server cluster provides services according to the service interface. The present invention can shorten the time when the server cluster stops providing services, quickly construct a service interface for the new master node to provide services, and reduce the impact of the failure of the master node on the business.

The method includes the steps of: Obtaining and storing first cluster information of the server cluster, where the first cluster information includes first master node information; After a predetermined time, obtaining second cluster information of the server cluster, where the second cluster information includes second master node information, and comparing the second cluster information with the first cluster information to determine whether the second master node information in the second cluster information is the same as the first master node information in the first cluster information; If the second master node information is different from the first master node information, determining whether the first master node of the server cluster has failed to rule out misoperations caused by network jitter; If the first master node fails, canceling the first service interface constructed according to the first master node information; Constructing a second service interface according to the second master node information, so that the second master node of the server cluster provides services to users according to the second service interface; Wherein, the first cluster information further includes first slave node information, and the second cluster information further includes second slave node information. The method further includes the steps of: If the second master node information is the same as the first master node information, determining whether the second slave node information in the second cluster information is the same as the first slave node information in the first cluster information; If the second slave node information is different from the first slave node information, storing the second cluster information to determine whether the server cluster has changed; The step of storing the second cluster information if the second slave node information is different from the first slave node information includes the steps of: Determining whether there are any offline slave nodes according to the second slave node information and the first slave node information; If there are offline slave nodes, determining whether the offline slave nodes have failed to prevent misoperations caused by network jitter; If the offline slave nodes have failed, storing the second cluster information; In the server cluster, the master node is suitable for sending the data in the service request to the slave nodes after receiving the service request, so that the slave nodes send confirmation information and store the data. The master node is also suitable for storing the data after receiving confirmation information from more than a predetermined number of slave nodes to determine the effective last time of the data when the master node fails.

2. The method according to claim 1, wherein, The server cluster provides services according to domain name information. The step of constructing the second service interface according to the second master node information includes: Constructing a second service interface according to the IP address of the second master node, so that when a user sends a service request to the server cluster through the domain name information, the server cluster calls the second service interface to determine the IP address of the second master node, and sends the service request to the second master node according to the IP address of the second master node.

3. The method according to claim 1 or 2, wherein The method further includes the steps of: Store the second cluster information to determine whether the server cluster has changed.

4. The method according to claim 1, wherein The predetermined number is half of the number of slave nodes in the server cluster.

5. The method according to claim 4, wherein, When the first master node fails, a slave node in the server cluster serves as the master node.

6. A computing device, comprising: One or more processors; A memory; And One or more means, the one or more means including instructions for performing the method according to any one of claims 1-5.

7. A computer-readable storage medium storing one or more programs, the one or more programs including instructions that, when executed by a computing device, cause the computing device to perform the method according to any one of claims 1-5.
