Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a configuration method for a distributed application coordination service node according to an embodiment of the present invention. In this embodiment, the execution subject of the configuration method of the distributed application coordination service node is a server of the distributed application coordination service. A configuration method of a distributed application coordination service node as shown in fig. 1 includes the following steps:
s11: receiving a distributed application coordination service node creation request; the distributed application coordination service node creation request carries a read-write permission inheritance identifier of a target distributed application coordination service node to be created and identifier information of a father node of the target distributed application coordination service node; the read-write permission inheritance identifier is used for representing whether to inherit the read-write permission of the father node.
In practical applications, a distributed system generally includes a client, a server, and at least two distributed nodes, where the distributed nodes may be distributed storage nodes or distributed processing nodes, and are not limited herein. The distributed application coordination service is used for providing consistency and coordination service for a distributed system, and in the embodiment of the invention, the distributed application coordination service can be zookeeper.
When the consistency and coordination management of the distributed system is realized through the distributed application coordination service, corresponding distributed application coordination service instances need to be deployed on each distributed node in the distributed system, and then the consistency and coordination between the distributed node and other distributed nodes are realized through the distributed application coordination service instances deployed on the distributed nodes.
Specifically, when a distributed application coordination service node corresponding to each distributed node in the distributed system needs to be created in a server of the distributed application coordination service, a developer may trigger a distributed application coordination service node creation request through a node information setting interface of the server of the distributed application coordination service, where the distributed application coordination service node creation request carries a read-write permission inheritance identifier of a target distributed application coordination service node to be created and identifier information of a parent node of the target distributed application coordination service node. The reading and writing authority inheritance identifier is used for representing whether to inherit the reading and writing authority of the father node. Illustratively, the value of the read-write permission inheritance identifier can be 0 or 1, wherein 0 represents that the read-write permission of the parent node is not inherited, and 1 represents that the read-write permission of the parent node is inherited. The identification information of the parent node of the target distributed application coordination service node to be created may be a name, a host number, or a Media Access Control (MAC) address of the parent node of the target distributed application coordination service node to be created.
The read-write permission inheritance identifier of the target distributed application coordination service node to be created and the identifier information of the father node of the target distributed application coordination service node to be created can be input through a node information setting interface of a server of the distributed application coordination service when a developer triggers a request for creating the distributed application coordination service node.
After a server of the distributed application coordination service receives a distributed application coordination service node creation request sent by a server of a distributed system, a read-write permission inheritance identifier of a target distributed application coordination service node to be created and identifier information of a father node of the target distributed application coordination service node are extracted from the distributed application coordination service node creation request.
S12: and if the read-write permission inheritance identifier carried by the establishment request of the distributed application coordination service node is used for representing the read-write permission of the inheritance parent node, acquiring the read-write permission information of the parent node of the target distributed application coordination service node based on the identification information of the parent node of the target distributed application coordination service node.
After the server of the distributed application coordination service extracts the read-write permission inheritance identifier of the target distributed application coordination service node to be created and the identification information of the father node of the target distributed application coordination service node from the creation request of the distributed application coordination service node, if the read-write permission inheritance identifier of the target distributed application coordination service node is detected to be used for representing the read-write permission of the inheritance father node, the read-write permission information of the father node of the target distributed application coordination service node is obtained based on the identification information of the father node of the target distributed application coordination service node. The read-write permission information of the node is used for describing permission that information stored in the node can be read or modified by a server or other nodes.
In the embodiment of the invention, the server of the distributed application coordination service stores the preset corresponding relation between the identification information of each configured distributed application coordination service node and the read-write permission information thereof. Since the father node of the target distributed application coordination service node is a configured distributed application coordination service node, the server of the distributed application coordination service may obtain the read-write permission information of the father node of the target distributed application coordination service node based on the preset corresponding relationship between the identification information of the father node of the target distributed application coordination service node, the identification information of the distributed application coordination service node, and the read-write permission information of the distributed application coordination service node.
S13: and determining the read-write permission information of the father node of the target distributed application coordination service node as the final read-write permission information of the target distributed application coordination service node.
After the server of the distributed application coordination service acquires the read-write permission information of the father node of the target distributed application coordination service node, the read-write permission information of the father node of the target distributed application coordination service node is determined as the final read-write permission information of the target distributed application coordination service node.
S14: and creating the target distributed application coordination service node under the father node of the target distributed application coordination service node, and configuring the read-write permission of the target distributed application coordination service node based on the final read-write permission information of the target distributed application coordination service node.
In the embodiment of the invention, after a server of the distributed application coordination service determines the final read-write permission information of the target distributed application coordination service node, the target distributed application coordination service node is established under a father node of the target distributed application coordination service node, and the read-write permission of the target distributed application coordination service node is configured based on the final read-write permission information of the target distributed application coordination service node.
As an embodiment of the present invention, after configuring the read-write permission of the target distributed application coordination service node, the server of the distributed application coordination service further obtains the basic information of the target distributed application coordination service node, and combines the final read-write permission information and the basic information of the target distributed application coordination service node to obtain the configuration information of the target distributed application coordination service instance corresponding to the target distributed application coordination service node. The basic information of the target distributed application coordination service node includes, but is not limited to, the name, the type, the operating system and other information of the target distributed application coordination service node.
And after the server of the distributed application coordination service obtains the configuration information of the target distributed application coordination service instance, the server sends the configuration information of the target distributed application coordination service instance to the server of the distributed system.
After receiving the configuration information of the target distributed application coordination service instance, a server of the distributed system deploys the target distributed application coordination service instance on a distributed node corresponding to the target distributed application coordination service node, and then realizes the uniformity and the coordination between the distributed node and other distributed nodes in the distributed system through the target distributed application coordination service instance.
As can be seen from the above, in the configuration method of the distributed application coordination service node provided in this embodiment, by setting the read-write permission inheritance identification bit and the identification information bit of the parent node in the request for creating the distributed application coordination service node, when the target distributed application coordination service node to be created needs to be configured with the read-write permission identical to the read-write permission of its parent node, the server of the distributed application coordination service can obtain the read-write permission information of the parent node of the target distributed application coordination service node based on the identification information of the parent node of the target distributed application coordination service node carried in the request for creating the distributed application coordination service node only by carrying the read-write permission inheritance identification for representing the read-write permission of the inheritance parent node and the identification information of the parent node of the target distributed application coordination service node in the request for creating the distributed application coordination service node, and the read-write permission of the target distributed application coordination service node is automatically configured based on the read-write permission information of the father node of the target distributed application coordination service node, so that a user does not need to manually input the read-write permission information of the target distributed application coordination service node, the configuration process of the distributed application coordination service node is simplified, and the configuration efficiency of the distributed application coordination service node is improved.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for configuring a distributed application coordination service node according to another embodiment of the present invention. With respect to the embodiment corresponding to fig. 1, the request for creating the distributed application coordination service node of this embodiment further carries initial read-write permission information of a target distributed application coordination service node to be created, and based on this, the configuration method of the distributed application coordination service node provided in this embodiment further includes, after S12 and before S14, S01 to S02, which are detailed as follows:
s01: and detecting whether the initial read-write permission information of the target distributed application coordination service node carried in the establishment request of the distributed application coordination service node is consistent with the read-write permission information of the father node of the target distributed application coordination service node.
In this embodiment, because the request for creating the distributed application coordination service node also carries the initial read-write permission information of the target distributed application coordination service node to be created, after the server of the distributed application coordination service acquires the read-write permission information of the parent node of the target distributed application coordination service node, the initial read-write permission information of the target distributed application coordination service node carried in the request for creating the distributed application coordination service node is compared with the read-write permission information of the parent node of the target distributed application coordination service node to detect whether the initial read-write permission information of the target distributed application coordination service node carried in the request for creating the distributed application coordination service node is consistent with the read-write permission information of the parent node of the target distributed application coordination service node.
S02: if the initial read-write permission information of the target distributed application coordination service node carried in the distributed application coordination service node creation request is inconsistent with the read-write permission information of the father node of the target distributed application coordination service node, integrating the initial read-write permission information of the target distributed application coordination service node with the read-write permission information of the father node of the target distributed application coordination service node to obtain the final read-write permission information of the target distributed application coordination service node.
If the server of the distributed application coordination service detects that the initial read-write permission information of the target distributed application coordination service node carried in the establishment request of the distributed application coordination service node is inconsistent with the read-write permission information of the father node of the target distributed application coordination service node, it indicates that the user wants to enable the target distributed application coordination service node to inherit the read-write permission of the father node of the target distributed application coordination service node and wants to further expand the read-write permission of the target distributed application coordination service node, and at the moment, the server of the distributed application coordination service integrates the initial read-write permission information of the target distributed application coordination service node with the read-write permission information of the father node of the target distributed application coordination service node to obtain the final read-write permission information of the target distributed application coordination service node.
In practical application, the step of integrating the initial read-write permission information of the target distributed application coordination service node and the read-write permission information of the parent node of the target distributed application coordination service node may be: and combining the initial read-write permission information of the target distributed application coordination service node with the read-write permission information of the father node of the target distributed application coordination service node. For example, if the initial read-write permission information of the target distributed application coordination service node only describes the read permission but not the write permission, and the read-write permission information of the parent node of the target distributed application coordination service node only describes the write permission but not the read permission, the read permission described by the initial read-write permission information of the target distributed application coordination service node is combined with the write permission described by the read-write permission information of the parent node of the target distributed application coordination service node, so as to obtain the final read-write permission information of the target distributed application coordination service node.
As still another embodiment of the present invention, as shown in fig. 3, after S01 and before S14, the method for configuring the distributed application coordination service node may further include S03, which is detailed as follows:
s03: and if the initial read-write permission information of the target distributed application coordination service node carried in the distributed application coordination service node creation request is consistent with the read-write permission information of the father node of the target distributed application coordination service node, determining the initial read-write permission information of the target distributed application coordination service node or the read-write permission information of the father node of the target distributed application coordination service node as the final read-write permission information of the target distributed application coordination service node.
In this embodiment, if the server of the distributed application coordination service detects that the initial read-write permission information of the target distributed application coordination service node carried in the request for creating the distributed application coordination service node is consistent with the read-write permission information of the parent node of the target distributed application coordination service node, it indicates that the user wants to allow the target distributed application coordination service node to directly inherit the read-write permission of its parent node, and at this time, the server of the distributed application coordination service determines the initial read-write permission information of the target distributed application coordination service node or the read-write permission information of the parent node of the target distributed application coordination service node as the final read-write permission information of the target distributed application coordination service node.
As can be seen from the above, the configuration method for the distributed application coordination service node provided in this embodiment allows the initial read-write permission information of the target distributed application coordination service node to be created to be carried in the creation request of the distributed application coordination service node, and when a user wants to make the target distributed application coordination service node inherit the read-write permission of its parent node and further extend the read-write permission of the target distributed application coordination service node, only the read-write permission information inconsistent with the read-write permission information of the parent node of the target distributed application coordination service node is required to be carried in the creation request of the distributed application coordination service node as the initial read-write permission information of the target distributed application coordination service node, so that the configuration efficiency of the distributed application coordination service node is improved.
Referring to fig. 4, fig. 4 is a flowchart illustrating a configuration method of a distributed application coordination service node according to another embodiment of the present invention. With respect to the embodiment corresponding to fig. 2, the configuration method of the distributed application coordination service node provided in this embodiment further includes, after S11 and before S14, S04, which is detailed as follows:
s04: and if the read-write permission inheritance identifier carried by the distributed application coordination service node creation request is used for representing the read-write permission of the non-inheritance parent node, determining the initial read-write permission information of the target distributed application coordination service node carried by the distributed application coordination service node creation request as the final read-write permission information of the target distributed application coordination service node.
In this embodiment, after the server of the distributed application coordination service extracts the read-write permission inheritance identifier of the target distributed application coordination service node to be created and the identification information of the parent node of the target distributed application coordination service node from the distributed application coordination service node creation request, if it is detected that the read-write permission inheritance identifier of the target distributed application coordination service node is used for representing the read-write permission of the non-inheritance parent node, the server of the distributed application coordination service extracts the initial read-write permission information of the target distributed application coordination service node to be created from the received distributed application coordination service node creation request, and determines the initial read-write permission information as the final read-write permission information of the target distributed application coordination service node.
As can be seen from the above, according to the configuration method of the distributed application coordination service node provided in this embodiment, when a user does not want a target distributed application coordination service node to inherit the read-write right of its parent node, only a read-write right inheritance identifier for representing the read-write right of the non-inherited parent node and initial read-write right information of the target distributed application coordination service node are carried in a request for creating the distributed application coordination service node, and a server of the distributed application coordination service can automatically configure the read-write right of the target distributed application coordination service node based on the initial read-write right information, so that the configuration efficiency of the distributed application coordination service node is improved.

The update range identifier is used for describing a range of the distributed application coordination service node with the read-write permission to be updated, and the update range identifier may include global update and local update. The global updating is used for representing that the read-write permission of the distributed application coordination service node to be updated and all the child nodes of the distributed application coordination service node to be updated are updated, and the local updating is used for representing that the read-write permission of the distributed application coordination service node to be updated is only updated.
S16: and if the updating range identifier carried in the read-write permission updating request is used for representing global updating, updating the read-write permission of the distributed application coordination service node to be updated and all the sub-nodes thereof based on the read-write permission information to be updated carried in the read-write permission updating request.
In this embodiment, when the server of the distributed application coordination service receives the read-write permission update request, if it is detected that the update range identifier carried in the read-write permission update request is used to represent global update, the server locates the distributed application coordination service node to be updated based on the identifier information of the distributed application coordination service node to be updated carried in the read-write permission update request, and updates the read-write permissions of the distributed application coordination service node to be updated and all child nodes thereof based on the read-write permission information to be updated carried in the read-write permission update request.
As an embodiment of the present invention, if the server of the distributed application coordination service detects that the update range identifier carried in the read/write permission update request is used to characterize local update, the server locates the distributed application coordination service node to be updated based on the identifier information of the distributed application coordination service node to be updated carried in the read/write permission update request, and updates the read/write permission of the distributed application coordination service node to be updated based on the read/write permission information to be updated carried in the read/write permission update request.
As can be seen from the above, in the configuration method of the distributed application coordination service node provided in this embodiment, by setting the update range identifier bit in the read-write permission update request, when a user wants to update the read-write permission of a certain distributed application coordination service node and all the child nodes thereof, the batch update of the read-write permission of the distributed application coordination service node can be realized only by carrying the update range identifier for representing the global update, the identifier information of the distributed application coordination service node to be updated, and the read-write permission information to be updated in the read-write permission update request, so that the update efficiency of the read-write permission of the distributed application coordination service node is improved.
