Online medical treatment is a new application of online in the medical field, and can be divided into data integration stages in the development process of medical informatization according to the characteristic of covering a 'surface'. Online medical treatment includes a variety of items such as health education, medical information inquiry, electronic health archives, disease risk assessment, online disease consultation, electronic prescription, remote consultation, remote medical treatment, and rehabilitation. In order to ensure safe operation of the system, the online medical platform system usually adopts double machine rooms. In a dual-computer room application scenario in the field of digital medical treatment, some component clusters need to sense the active/standby information of the current computer room, and can perform the active/standby switching function for the component clusters. Although some components such as distributed scheduling service, tair cache and the like can be distributed in the dual computer rooms, the service itself needs to know whether the currently running computer room is a main system or a standby system (for example, tair needs to write into a main reading computer room because of real-time performance and data consistency), and when abnormal maintenance and other reasons occur, main-standby switching of a single component cluster system is needed, and dirty data can be avoided in the switching process. Therefore, a unified double-machine-room switching platform is needed for management and support. In order to solve the problems in the related art, an embodiment of the present application provides a method for switching between active and standby components of a component cluster system.
An application scenario of the method according to the embodiment of the present application is shown in fig. 1, where the application scenario includes a first server 110, a second server 120, and a monitoring server 130, a first component cluster system and a second component cluster system are respectively deployed in the first server 110 and the second server 120, and interaction data between the first component cluster system and the second component cluster system is relayed through the monitoring server 130. The monitoring server 130 receives a normal state reporting signal sent by the first component cluster system according to a first preset period duration, and forwards the reporting signal to the second component cluster system; the monitoring server 130 updates the validity period of the first component cluster system as a main system according to the second preset period duration; the monitoring server 130 detects whether the validity period is updated within a preset duration, and determines whether the working state of the first component cluster system reaches a preset main/standby switching condition; the monitoring server 130 changes the working state of the first component cluster system from the main system state to the standby system state and changes the working state of the second component cluster system from the standby system state to the main system state according to the preset main/standby switching condition. The method of the embodiment of the application can automatically realize the main-standby switching of the component cluster system when the main system is abnormally operated, so that the working efficiency is improved, the switching timeliness is improved, and the labor cost is reduced.
In the embodiment of the application, ZK, namely zookeeper, is a distributed coordination service, and can store the states of the main component, the standby component, each node and the like. ZooKeeper is a distributed, open source distributed application coordination service, is an open source implementation of Chubby by Google, and is an important component of Hadoop and Hbase. The software is used for providing a consistency service for distributed application, and the provided functions comprise: configuration maintenance, domain name service, distributed synchronization, group service, etc. The ZooKeeper aims to package complex key services which are easy to make mistakes, and provides a simple and easy-to-use interface and a system with high performance and stable functions for a user. GMS is short for a dual-computer-room master-standby switching platform. The GMS is mainly divided into a GMS-client module (in a two-party library jar packet form) and a GMS-server module, and the module can perform active-standby switching on the GMS only after the client module is integrated.
The Client contains the following two functions: 1. and (3) reporting the state: reporting the upper and lower line states of each node of the component; 2. monitoring the main and standby states: and monitoring the state of the component and responding to the change in time. If the monitored component is changed to the read-only state, the write-forbidden operation of the component can be executed.
The Server module comprises the following functions: 1. managing the information of the machine room; 2. managing the state of the component; 3. managing the components; and 4, IDC active/standby switching function.
Referring to fig. 2, an embodiment of the present application provides a main/standby switching method of a component cluster system, which is applied to a monitoring server, where the main/standby switching method may include steps S10 to S40:
s10, receiving a normal state report signal sent by the first component cluster system according to a first preset period duration.
The state normal report signal is used for indicating that the first component cluster system is in a normal state of the main system. The first component cluster system is a main system of the target service, and the second component cluster system is a standby system of the target service.
Specifically, the first component cluster system sends a normal state report signal to the monitoring server to indicate that the current working state is normal to the monitoring server. The first preset period duration may be preset according to actual needs, and may be set to 1 second, 2 seconds, 3 seconds, or the like, for example.
And S20, updating the validity period of the first component cluster system as a main system according to a second preset period.
And if the monitoring server receives the report signal within the second preset period duration, the monitoring server indicates that the working state of the first component cluster system is not abnormal. If the monitoring server does not receive the state normal backup signal within the second preset period duration, it indicates that the working state of the first component cluster system is abnormal, and the monitoring server may further detect whether the master/slave switching is required.
S30, detecting whether the validity period is updated within the preset duration, and determining whether the working state of the first component cluster system reaches a preset main/standby switching condition.
Specifically, if the validity period is not updated within the preset duration, it is determined that the working state of the first component cluster system reaches the preset primary/secondary switching condition, and if the validity period is updated within the preset duration, it is determined that the working state of the first component cluster system does not reach the preset primary/secondary switching condition.
In some embodiments, determining whether the working state of the first component cluster system reaches a preset active/standby switching condition includes: if the validity period is not updated within the preset duration, determining that the working state of the first component cluster system reaches a preset main/standby switching condition; otherwise, determining that the preset main/standby switching condition is not met.
And S40, if the preset main-standby switching condition is met, changing the working state of the first component cluster system from a main system state to a standby system state, and changing the working state of the second component cluster system from the standby system state to the main system state.
The state normal report signal is used for indicating that the first component cluster system is in a normal state of a main system state, the validity period is determined based on a timestamp and a preset duration, the timestamp is used for indicating the starting time of the validity period, and the preset duration is longer than the second preset period.
Specifically, the second preset period duration is set to be less than the preset duration, so that the updating operation of the validity period within the preset duration can be ensured when the first component cluster system is in a normal working state.
For example, assuming that the preset duration is 50 seconds, the second preset period duration may be set to 10 seconds, that is, the first component cluster system sends the validity period update instruction to the monitoring server every 10 seconds. If the initial timestamp of the current validity period is 32 minutes and 45 seconds at 10 hours and the preset duration is 50 seconds, the current validity period is 32 minutes and 45 seconds to 10 minutes and 32 minutes and 35 seconds at 10 hours, and if a first validity period updating instruction is received after 10 seconds, the validity period is updated to 10 minutes and 32 minutes and 55 seconds to 10 minutes and 32 minutes and 45 seconds.
As shown in fig. 3, in some embodiments, the changing the operating state of the first component cluster system from a main system state to a standby system state and the changing the operating state of the second component cluster system from the standby system state to the main system state includes:
s401, setting the first component cluster system to be in a read-only state through a distributed application program coordination service;
s402, changing the working state of the first component cluster system in the distributed application program coordination service into a standby system state;
and S403, setting the second component cluster system to be in a main system state through the distributed application program coordination service according to the working state of the second component cluster system as a ready state.
In the process of switching the main and standby, a read-only (readonly) state is an intermediate state in the process of switching the main and standby, and when a corresponding component monitors the state change, the component node integrated with the GMS-client can execute write-forbidding operation of each component, namely, enter the read-only state, so that dirty data is prevented from being generated in the process of switching the main and standby, and then the state of the node on zk can be automatically changed into a ready-to-standby state.
Ready state means that the node state of a component becomes ready after it enters the read-only state and writes the state back to zk; when all nodes of a component enter the read-only state and write back to zk, the state of the component changes to the ready-to-use state.
In some embodiments, the changing the operating state of the first component cluster system from a main system state to a standby system state and the changing the operating state of the second component cluster system from the standby system state to the main system state further includes:
s404, storing state change data of the first component cluster system and the second component cluster system through the distributed application program coordination service.
In some embodiments, the changing the operating state of the first component cluster system from a primary system state to a standby system state includes:
determining the moment when the validity period finishes updating within the preset duration; updating a verification timestamp by using the updating completion time, wherein an initial value of the verification timestamp is the time when the first component cluster system successfully updates the validity period for the first time; and responding to the fact that the difference value between the checking timestamp and the actual time is larger than the preset duration, and switching the service state of the first component cluster system from the main system to the standby system.
In the operation process of the first component cluster system, each time the first component cluster system receives a notification that the validity period is updated successfully, the timestamp of the notification is updated into the verification timestamp, and the duration of the notification that the update is not successfully received is determined based on the difference between the verification timestamp and the actual time. For example, if the time when the validity period is successfully updated for the first time by the first component cluster system is 9 hours 38 minutes 36 seconds, the initial value of the check timestamp is 9 hours 38 minutes 36 seconds. For example, the timestamp of when the update success notification is received for the first time is 38 minutes and 36 seconds at time 9, and if no other update success notification is received at time 39 minutes and 26 seconds at time 9, it may be determined that the time length during which the update success notification is not received is 50 seconds, and if the preset duration is 50 seconds, it may be determined that the update success notification is not received within the preset duration, and thus it may be determined that the update of the validity period is not completed within the preset duration.
The monitoring server may have integrated thereon GMS and ZK. In a specific example shown in fig. 4, GMS and ZK cooperate with each other to implement active/standby switching. The monitoring server selects the corresponding component to start the switching process. GMS changes the state of the component in zookeeper: main- > read-only state. And each node of the component respectively monitors that the corresponding write-forbidding logic is executed after the state is changed (main- > read-only), and writes back the state of the node from ready to ZK after the state is finished. When all nodes under the module are in the ready state, the GMS changes the overall state of the module to the ready state, which indicates that the active/standby switching is possible. GMS makes the state of the assembly from ready-to-standby, and the original main computer room assembly of the assembly monitors the state change and adjusts the main computer room assembly into a standby cluster. GMS makes the component original backup-master, the component original backup component monitors the state change and adjusts the component to be a master component cluster, and the master-slave switching is finished. According to the method, dirty data can be prevented from being generated through write-inhibit read-only operation in the active-standby switching process of the components, one-key active-standby switching can be realized for a certain component through a state machine mechanism, and unified management can be realized on component clusters needing to be distinguished from active-standby components.
In some embodiments, the method may further comprise: and if the working state of the first component cluster system is determined to reach the preset main/standby switching condition, sending a corresponding prompt signal. The prompt signal is used for reminding a worker that the current working state of the first component cluster system reaches a preset main/standby switching condition.
In some embodiments, the method may further comprise: and sending a master-slave system state switching completion signal of the first component cluster system and the second component cluster system. The master-slave system state switching completion signal is used for reminding a worker that the master-slave system state switching of the first component cluster system and the second component cluster system is completed.
The master-slave switching method of the component cluster system provided by the embodiment of the application receives a normal state reporting signal sent by a first preset period time of a first component cluster system, forwards the reporting signal to a second component cluster system, updates the validity period of the first component cluster system as a master system according to a second preset period time, detects whether the validity period is updated within the preset duration time, determines whether the working state of the first component cluster system reaches a preset master-slave switching condition, changes the working state of the first component cluster system from the master system state to a slave system state if the preset master-slave switching condition is met, and changes the working state of the second component cluster system from the slave system state to the master system state, so that the master-slave switching of the component cluster system can be automatically realized when the master system is abnormally operated, the working efficiency is improved, the switching degree is improved, and the labor cost is reduced.
