具体实施方式Detailed ways

为了更好的理解上述技术方案，下面将结合说明书附图及具体的实施方式对上述技术方案进行详细的说明，应当理解本申请实施例以及实施例中的具体特征是对本申请技术方案的详细的说明，而不是对本申请技术方案的限定，在不冲突的情况下，本申请实施例以及实施例中的技术特征可以相互结合。In order to better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the drawings and specific implementations of the specification. It should be understood that the embodiments of the application and the specific features in the embodiments are detailed to the technical solutions of the application. Note, rather than limiting the technical solution of the present application, the embodiments of the present application and the technical features in the embodiments can be combined with each other if there is no conflict.

如图1所示，为本申请实施例提供的一种配置管理***的架构示意图。As shown in FIG. 1, it is a schematic structural diagram of a configuration management system provided by an embodiment of this application.

图1示出的架构包括：应用配置接口、中心集群、边缘集群和应用主机。该架构可用于统一管理分布式应用***中的各应用***的配置信息。需要说明的是，图1示出的架构仅作为一个示例，图1示出的架构还可以做多种变形，举例来说，边缘集群的数量不做限定，各集群中节点的数量不做限定，应用主机的数量不做限定等。本实施例所提供的配置管理***可用于对分布式应用***中的各应用***对应的配置信息进行统一管理。The architecture shown in Figure 1 includes: application configuration interface, central cluster, edge cluster, and application host. This architecture can be used to uniformly manage the configuration information of each application system in a distributed application system. It should be noted that the architecture shown in Figure 1 is only an example, and the architecture shown in Figure 1 can also be modified in many ways. For example, the number of edge clusters is not limited, and the number of nodes in each cluster is not limited. , The number of application hosts is not limited. The configuration management system provided in this embodiment can be used to uniformly manage the configuration information corresponding to each application system in the distributed application system.

应用配置接口(即图示中的web应用服务)：修改配置信息的唯一入口，提供配置信息操作界面，用于接收上游应用***(即分布式应用***的服务端)对配置信息的新增、修改及删除等操作，并对应生成配置信息更新指令。也就是说，各应用***对配置信息的更新，只能通过应用配置接口进行操作，保证了配置信息修改入口的统一性。其中，应用配置接口所提供的操作界面可基于web浏览器、HTML5页面来实现。Application configuration interface (ie the web application service in the figure): The only entry for modifying configuration information, providing configuration information operation interface, used to receive the upstream application system (that is, the server of the distributed application system) to the new configuration information, Modify and delete operations, and generate configuration information update instructions accordingly. That is to say, each application system can only operate through the application configuration interface to update the configuration information, which ensures the unity of the configuration information modification entry. Among them, the operation interface provided by the application configuration interface can be implemented based on a web browser and an HTML5 page.

中心集群：用于获取应用配置接口生成的配置信息更新指令，并且是可执行所述更新指令的唯一集群，以实现对配置信息修改，保证了配置信息修改执行的唯一性。Central cluster: used to obtain the configuration information update instructions generated by the application configuration interface, and is the only cluster that can execute the update instructions, so as to modify the configuration information and ensure the uniqueness of the execution of the configuration information modification.

在初始化阶段，中心集群启动后，配置管理***将全量配置信息初始化到中心集群中，由中心集群内部保证中心集群中的各个节点存储的配置信息保持一致，再由中心集群将全量配置信息同步至该架构中的各边缘集群。需要说明的是，全量配置信息包含接入配置管理***的所有应用***的配置信息，中心集群可基于该全量配置信息的进行更新。由于中心集群可包含多个节点，各节点可分布在不同机器设备上，各节点上存储的配置信息是相同的，即便中心集群中有部分节点发生故障，也可以通过其他节点来接替进行配置信息的存储、修改和同步，从而提高容错性、可用性。In the initialization phase, after the central cluster is started, the configuration management system initializes all configuration information to the central cluster. The central cluster ensures that the configuration information stored by each node in the central cluster is consistent, and then the central cluster synchronizes the full configuration information to the central cluster. Each edge cluster in the architecture. It should be noted that the full configuration information includes configuration information of all application systems connected to the configuration management system, and the central cluster can be updated based on the full configuration information. Since the central cluster can contain multiple nodes, each node can be distributed on different machines and equipment, and the configuration information stored on each node is the same. Even if some nodes in the central cluster fail, other nodes can be used to replace the configuration information. The storage, modification and synchronization of the system can improve fault tolerance and availability.

中心集群完成初始化后具体可以通过执行所述更新指令来实现配置信息的更新，具体可包含以下配置项。After the central cluster is initialized, the configuration information can be updated by executing the update instruction, which can specifically include the following configuration items.

(1)新增配置项，则在各中心节点上的当前配置信息中新增该配置项。(1) When a new configuration item is added, the configuration item is added to the current configuration information on each central node.

(2)修改配置项，则在各中心节点上的当前配置信息中找到该配置项，修改其值。(2) Modify a configuration item, find the configuration item in the current configuration information on each central node, and modify its value.

(3)删除配置项，则在各中心节点上的当前配置信息中找到该配置项，并删除。(3) To delete a configuration item, find the configuration item in the current configuration information on each central node and delete it.

边缘集群：配置管理***的架构中可包含多个边缘集群，边缘集群可从中心集群同步获取配置信息。在初始化阶段，各边缘集群可从中心集群同步获取初始化全量配置信息，并保证内部各个节点存储的配置信息保持一致。在初始化后，可进一步实时同步中心集群中的配置信息，边缘集群与中心集群的同步可以通过复制镜像(make-mirror)的方式进行。与中心集群类似，边缘集群中也有多个节点，一个节点发生故障后，同样可以通过其他节点来接替进行配置信息的存储、修改和同步，从而提高容错性、可用性。Edge cluster: The architecture of the configuration management system can contain multiple edge clusters, and the edge cluster can obtain configuration information synchronously from the central cluster. In the initialization phase, each edge cluster can synchronously obtain the initial full configuration information from the central cluster, and ensure that the configuration information stored by each internal node is consistent. After initialization, the configuration information in the central cluster can be further synchronized in real time, and the synchronization between the edge cluster and the central cluster can be performed by means of copy mirroring (make-mirror). Similar to a central cluster, there are multiple nodes in an edge cluster. After a node fails, other nodes can also be used to store, modify, and synchronize configuration information, thereby improving fault tolerance and availability.

应用主机：应用主机运行有应用***的客户端程序，是配置信息的使用者。应用主机可在初始化阶段指定配置集群，并从配置集群中选取一个作为主配置集群，并从主配置集群上获取所需的配置信息；并在初始化后开启监听线程，对主配置集群进行监听，实时监听所需要配置信息是否发生变更，如有变更，则可从主配置集群获取变更后的配置信息。Application host: The application host runs a client program with an application system and is a user of configuration information. The application host can specify the configuration cluster during the initialization phase, and select one of the configuration clusters as the main configuration cluster, and obtain the required configuration information from the main configuration cluster; and start the monitoring thread after initialization to monitor the main configuration cluster. Monitor in real time whether the required configuration information has changed. If there is any change, you can obtain the changed configuration information from the main configuration cluster.

其中主配置集群的选择，具体可以包含以下方式：若应用主机与中心集群通讯状态良好(举例来说，应用主机与中心集群在同一局域网，或地理位置较近，可认为通讯状态良好)，则直接将中心集群作为主配置集群；若应用主机与中心集群通讯状态不佳(举例来说，应用主机与中心集群不在同一局域网，或地理位置较远，则认为通讯状态不佳)，则可以从被指定为配置集群的边缘集群中，选择一与其通讯状态良好的边缘集群作为主配置集群这种方式可以最大化降低通信状态对应用主机的影响，同时可指定中心集群及至少一可与应用主机正常通信的边缘集群作为辅配置集群，以作为备用的主配置集群。The selection of the main configuration cluster can specifically include the following methods: if the communication status between the application host and the central cluster is good (for example, if the application host and the central cluster are in the same local area network, or the geographical location is close, the communication status can be considered good), then Directly use the central cluster as the main configuration cluster; if the communication status between the application host and the central cluster is poor (for example, if the application host and the central cluster are not in the same local area network, or the geographical location is far away, the communication status is considered poor), you can use Among the edge clusters designated as the configuration cluster, select an edge cluster with good communication status as the main configuration cluster. This method can minimize the impact of the communication status on the application host. At the same time, the central cluster and at least one application host can be designated The edge cluster that communicates normally serves as a secondary configuration cluster and serves as a backup primary configuration cluster.

应用主机可以指定一个或多个配置集群，用于获取所需的配置信息。但是，同一时刻只能从主配置集群进行交互，用于对获取最新的配置信息，当主配置集群发生故障后，应用主机可以从辅配置集群中重新选择一个集群，作为主配置集群。The application host can specify one or more configuration clusters to obtain the required configuration information. However, you can only interact from the main configuration cluster at the same time to obtain the latest configuration information. When the main configuration cluster fails, the application host can reselect a cluster from the auxiliary configuration cluster as the main configuration cluster.

具体的，应用主机可通过嵌入的软件开发工具包(Software development kit，SDK)文件来实现接入配置管理***。通过SDK编写程序，为应用主机和主配置集群提供交互的应用程序接口，还可以通过SDK实现应用主机对主配置集群的选择和监听，以及自动切换主配置集群和重连机制的功能写入，从而应用主机可支持自动切换配置集群和重连机制。Specifically, the application host can implement access to the configuration management system through an embedded software development kit (SDK) file. Programs are written through the SDK to provide interactive application program interfaces for the application host and the main configuration cluster. The selection and monitoring of the main configuration cluster by the application host can also be realized through the SDK, as well as the automatic switching of the main configuration cluster and the reconnection mechanism. Thus, the application host can support automatic switch configuration cluster and reconnection mechanism.

更具体的，本申请中的sdk工具，可以在应用主机的客户端集成后，从主配置集群获取应用主机所需的配置信息，并把所需配置信息加载到本地内存中，如此一来，应用主机可直接使用本地内存中的配置信息，对存在高并发请求的***，使用效率有显著的提高，而且即使所有的配置集群都无法提供服务，客户端仍然有配置信息可用，充分解耦，这对有高可用要求的***来说，至关重要，sdk可实现内部自动检测通讯配置集群的健康状态，并自动切换，可以有效降低故障处理响应时间和人工维护成本。More specifically, the SDK tool in this application can obtain the configuration information required by the application host from the main configuration cluster after the client of the application host is integrated, and load the required configuration information into the local memory. In this way, The application host can directly use the configuration information in the local memory. For systems with high concurrent requests, the use efficiency is significantly improved, and even if all configuration clusters cannot provide services, the client still has configuration information available, which is fully decoupled. This is very important for systems with high availability requirements. The SDK can automatically detect the health status of the communication configuration cluster and switch automatically, which can effectively reduce the fault handling response time and manual maintenance costs.

该架构中，通过配置信息管理***实现对各应用***的配置信息的统一管理，使得应用***中的业务***和配置管理充分解耦，有效地降低了配置信息管理与业务应用程序的耦合度，并通过中心集群和边缘集群对配置信息进行更新和存储，可使得应用***的客户端随时获取配置信息。In this architecture, the unified management of the configuration information of each application system is realized through the configuration information management system, so that the business system and configuration management in the application system are fully decoupled, and the coupling between configuration information management and business applications is effectively reduced. And through the central cluster and edge clusters to update and store the configuration information, the client of the application system can obtain the configuration information at any time.

该架构中，配置信息存入中心配置集群和边缘集群时，可以进行加密，并且在应用主机请求接入时，颁发只读权限的证书给应用主机，配置信息的写操作只能在最上层的统一入口即应用配置接口上进行，以此防止任一证书泄漏后，导致高敏感度的配置信息泄漏和被随意变更。由于分发的证书是只有只读权限的证书，即使证书泄漏，也只能获取到加密后的数据，并且无法更改配置数据，提高整个工具的安全性，以此满足配置信息敏感度高的场景。In this architecture, when the configuration information is stored in the central configuration cluster and edge cluster, it can be encrypted, and when the application host requests access, a certificate with read-only permission is issued to the application host, and the configuration information can only be written in the uppermost layer. The unified entry is performed on the application configuration interface, so as to prevent any certificate from being leaked, resulting in highly sensitive configuration information leakage and random changes. Since the distributed certificate is a certificate with read-only permission, even if the certificate is leaked, only the encrypted data can be obtained, and the configuration data cannot be changed, which improves the security of the entire tool and meets the scenarios with high configuration information sensitivity.

需要说明的是，中心集群和各边缘集群可采用分布式的键值对数据存储***(etcd)集群。etcd集群是高可用***，用以提高整个工具的可用性，降低配置管理***的宕机对具体业务***造成的影响。It should be noted that the central cluster and each edge cluster can adopt a distributed key-value pair data storage system (etcd) cluster. The etcd cluster is a highly available system to improve the availability of the entire tool and reduce the impact of configuration management system downtime on specific business systems.

如上文所述，应用主机在接入配置管理***时，可指定配置集群，并选择主配置集群，从主配置集群中获取所需的配置信息，并通过对主配置集群的监听来获取配置更新，以保证本地存有最新的配置信息。As mentioned above, when the application host accesses the configuration management system, it can specify the configuration cluster and select the main configuration cluster, obtain the required configuration information from the main configuration cluster, and obtain configuration updates by monitoring the main configuration cluster To ensure that the latest configuration information is stored locally.

具体而言，应用主机可在监听到主配置集群上有对其所需的配置信息进行更新时，直接从主配置集群上获取最新的配置信息，并替换本地已保存的配置信息。为了减少应用主机与集群间的数据传输量，也可从主配置集群上获取配置更新，并基于配置更新对本地配置信息进行修改，以得到最新的配置信息。Specifically, the application host can directly obtain the latest configuration information from the main configuration cluster and replace the locally saved configuration information when it monitors that there is an update to the configuration information it needs on the main configuration cluster. In order to reduce the amount of data transmission between the application host and the cluster, configuration updates can also be obtained from the main configuration cluster, and the local configuration information can be modified based on the configuration updates to obtain the latest configuration information.

例如，应用主机实时监听主配置集群以获取配置更新的步骤可以包含：所述应用主机实时监听所述主配置集群发布的更新消息，并从收到的更新消息中获取配置更新，其中，所述更新消息为所述主配置集群确定自身管理的配置信息发生更新时发布的，如此一来，应用主机在获取到配置更新时，还需确认该配置更新是否针对本机所需的配置信息，若是，则基于该配置更新进行本地配置信息的更新，若否，则可直接丢弃。For example, the step of the application host monitoring the main configuration cluster in real time to obtain configuration updates may include: the application host monitoring the update messages issued by the main configuration cluster in real time, and obtaining configuration updates from the received update messages, wherein the The update message is issued when the main configuration cluster determines that the configuration information managed by itself is updated. In this way, when the application host obtains the configuration update, it also needs to confirm whether the configuration update is for the configuration information required by the machine. , The local configuration information is updated based on the configuration update, if not, it can be discarded directly.

步骤202：应用主机若确定无法与所述主配置集群正常通信，则停止对所述主配置集群的监听，同时从可用的配置集群中重新确定出主配置集群，并返回至所述监听步骤。Step 202: If the application host determines that it cannot communicate with the main configuration cluster normally, it stops monitoring the main configuration cluster, and at the same time re-determines the main configuration cluster from the available configuration clusters, and returns to the monitoring step.

具体而言，应用主机确定是否与主配置集群正常通信的方法可包含：监听接收主配置集群周期性发送的心跳消息，若接收周期异常，或无法接收到心跳消息，则确定与主配置集群无法正常通信。Specifically, the method for the application host to determine whether it normally communicates with the main configuration cluster may include: monitoring and receiving heartbeat messages periodically sent by the main configuration cluster. If the receiving cycle is abnormal or the heartbeat message cannot be received, it is determined that the main configuration cluster cannot be communicated with. Normal communication.

当应用主机若确定无法与主配置集群正常通信时，应用主机可停止对主配置集群的监听，同时，将该主配置集群设定为不可用配置集群，可以理解的是，各应用主机与各配置集群的通信状态可能会发生异常，当应用主机发现与配置集群无法正常通信时，可将该配置集群置为不可用，同时应用主机可对对不可用配置集群其进行监测，以获取与不可用配置集群的通信状态，若确定可正常通信，则可重新将不可用配置集群设定其为可用。When the application host determines that it cannot communicate with the main configuration cluster normally, the application host can stop monitoring the main configuration cluster, and at the same time, set the main configuration cluster as an unavailable configuration cluster. The communication status of the configuration cluster may be abnormal. When the application host finds that it cannot communicate with the configuration cluster normally, the configuration cluster can be set as unavailable. At the same time, the application host can monitor the unavailable configuration cluster to obtain the status of unavailability. With the communication status of the configuration cluster, if it is determined that the communication can be normal, the unavailable configuration cluster can be set as available again.

当应用主机确定无法与主配置集群正常通信时，可从可用的配置集群中重新指定主配置集群，作为当前主配置集群。When the application host determines that it cannot communicate with the main configuration cluster normally, it can re-designate the main configuration cluster from the available configuration clusters as the current main configuration cluster.

举例来说，应用主机嵌入的SDK中配置了中心集群、边缘集群1和边缘集群2三个配置集群，其中，在初始阶段，基于预设规则指定边缘集群1为主配置集群，中心集群和边缘集群2为辅配置集群，并与边缘集群1进行数据交互；当应用主机确定边缘集群1的所有节点都不可用时，可重新指定边缘集群2作为主配置集群，具体可以按照周期与主配置集群进行心跳测试，如果在一段设定时间段内没收到来自主配置集群的心跳消息，则可确定无法与主配置集群进行正常通信，并可重新从中心集群和边缘集群2中重新确定出主配置集群，并进行监听。For example, the SDK embedded in the application host is configured with three configuration clusters: central cluster, edge cluster 1 and edge cluster 2. In the initial stage, edge cluster 1 is designated as the main configuration cluster, central cluster and edge cluster based on preset rules. Cluster 2 is a secondary configuration cluster and performs data interaction with edge cluster 1. When the application host determines that all nodes of edge cluster 1 are unavailable, edge cluster 2 can be re-designated as the main configuration cluster, which can be performed in accordance with the cycle and the main configuration cluster. Heartbeat test, if the heartbeat message from the main configuration cluster is not received within a set period of time, it can be determined that normal communication with the main configuration cluster cannot be performed, and the main configuration cluster can be re-determined from the central cluster and edge cluster 2. And monitor it.

从所述应用主机的可用的配置集群中重新确定出主配置集群的具体实施方式可包含：所述应用主机按照设定策略从所述可用的配置集群中重新确定出主配置集群；所述设定策略包括以下至少一项或多项的组合：所述重新确定出的主配置集群与所述应用主机位于同一局域网；所述重新确定出的主配置集群与所述应用主机之间的通信速率符合设定条件。The specific implementation manner of re-determining the main configuration cluster from the available configuration clusters of the application host may include: the application host re-determines the main configuration cluster from the available configuration clusters according to a set policy; The predetermined strategy includes at least one or a combination of the following: the re-determined main configuration cluster and the application host are located in the same local area network; the re-determined main configuration cluster and the application host communication rate Meet the set conditions.

举例来说，当将与所述应用主机之间的通信速率大于预设速率阈值的辅配置集群，作为重新确定出的主配置集群。For example, when a secondary configuration cluster whose communication rate with the application host is greater than a preset rate threshold is used as the re-determined primary configuration cluster.

在一实施中，在应用主机指定配置集群时，可先分别对各集群的网络状态进行探测，包括是否位于同一局域网的判断，以及通信速率的确定，并基于探测结果进行排序，并筛选出符合预设规则的集群作为指定的配置集群，并指定条件最优的为主配置集群，其他的为辅配置集群，并保存各辅配置集群的顺序，这样一来，在从辅配置集群中指定新的主配置集群时，可直接基于保存的顺序快速选择出条件最优的辅配置集群。In one implementation, when the application host specifies the configuration of the cluster, the network status of each cluster can be detected separately, including the judgment of whether they are located in the same local area network, and the determination of the communication rate, and sort based on the detection results, and filter out the matching The cluster with preset rules is used as the designated configuration cluster, and the best configuration is designated as the primary configuration cluster, and the others are secondary configuration clusters. The order of each secondary configuration cluster is saved. In this way, the new configuration cluster is specified in the secondary configuration cluster. When the main configuration cluster is selected, the auxiliary configuration cluster with the best conditions can be quickly selected based on the saved sequence.

例如，所述配置管理***的各集群以键值对方式存储各应用***的配置信息；更新所述应用主机中存储的配置信息可以包含：所述应用主机以键值对的方式更新所述应用主机中存储的配置信息。通过键值对方式存储配置信息便于应用主机快速获取配置信息，同时也便于更新应用主机中存储的配置信息，提升了配置信息更新和获取的效率。For example, each cluster of the configuration management system stores the configuration information of each application system in the form of key-value pairs; updating the configuration information stored in the application host may include: the application host updates the application in the form of key-value pairs Configuration information stored in the host. Storing the configuration information in the key-value pair method facilitates the application host to quickly obtain the configuration information, and at the same time, it is convenient to update the configuration information stored in the application host, which improves the efficiency of updating and obtaining the configuration information.

例如：所述应用主机在初次接入配置管理***时，可获取与所需配置信息对应的权限证书，并基于所述权限证书与所述主配置集群建立连接。***颁发给应用主机的是只读权限的证书，应用主机不能擅自对配置信息修改，而且应用主机根据所述证书才能监听所述主配置集群中所述应用主机的配置信息，从而提升了配置信息获取的安全性。For example, when the application host accesses the configuration management system for the first time, it can obtain an authority certificate corresponding to the required configuration information, and establish a connection with the main configuration cluster based on the authority certificate. The system issues a certificate with read-only permission to the application host. The application host cannot modify the configuration information without authorization, and the application host can monitor the configuration information of the application host in the main configuration cluster according to the certificate, thereby improving the configuration information Security of access.
