Description

Technical Field

The present application relates to the field of computer technologies, and in particular, to a method, an apparatus, an electronic device, and a storage medium for updating configuration information.

Background

With the development of cloud computing, a large number of enterprises plan or are using cloud computing, and cloud computing models include public clouds and private clouds. Public clouds generally refer to clouds that third party provider users can use, and public clouds are generally available over the Internet, and may be free or low cost. Private clouds are built for a single customer use, providing the most effective control of data security and quality of service.

Network resources, such as virtual network cards, virtual routers, virtual firewalls, virtual switches, etc., are indispensable in both private and public cloud environments, and the implementation of these network resource functions depends on network flow tables that provide a basis for forwarding data, and the neutron service in Openstack also depends on the network flow tables. The network flow table may be lost or abnormal, which may cause the malfunction of the virtual machine network communication function. If the online neutral service needs to update the adjustment configuration, the service is restarted after the configuration file is required to be modified, and the neutral restart service can trigger the emptying and reconstruction of the network flow table, which may cause network paralysis of the virtual machine in some large-scale cloud environments and bring great influence to user service.

The specific manner of obtaining the configuration update request may be implemented by the following embodiments.

In one possible implementation manner, the execution subject of the method is a neutron proxy node, and the configuration update request is obtained, which includes at least one of the following:

receiving a configuration updating request sent by a control node, wherein the configuration updating request is determined by the control node through a received first representational state transfer (Representational State Transfer, REST) restful request;

In practical application, the configuration update request may be determined by using a hypertext transfer protocol (Hyper Text Transfer Protocol, HTTP) network transmission and a request received through a restful application program interface (Application Programming Interface, API), when the execution body is a neutron proxy node, the control node receives a first restful request through a server process, determines the configuration update request according to the first restful request, where the configuration update request may be an update request for the server process of the control node, or may be an update request for the neutron proxy node, and when the configuration update request determined by the control node is for the neutron proxy node, sends the configuration update request to the corresponding neutron proxy node, and the neutron proxy node receives the configuration update request and subsequently processes the configuration update request; the configuration update request may also be a command line request directly input by a user in the form of an input command, whether the control node or the neutron proxy node, may create a thread in which the configuration update request in the form of a command line is obtained by monitoring the corresponding Unix socket file.

In the embodiment of the application, the configuration update request mode is obtained through the restful request mode, so that the method can be applied to an operation and maintenance system of the private cloud for operation and maintenance management staff to use, and furthermore, a client receiving the restful request can be provided for any third party call, such as a configuration center.

and receiving a first Command Line Interface (CLI) configuration update request, and writing the received configuration update request into a first Unix socket file.

In practical application, the neutron proxy node receives a configuration update request in the form of a command line, and writes the configuration update request into a Unix socket file. The Unix socket file is a local file of a preconfigured neutron proxy node, and communication between different processes can be realized through the Unix socket file. The Unix socket only performs data copying, and does not perform complex operations such as adding and deleting message heads, calculating checksums, calculating message sequences and the like which need to be processed in a network protocol stack, so that the Unix socket is used for communication between different processes of the same computer, and the operation is simple and efficient.

The proxy node of the neutron may also be a proxy node of a different node in the neutron service component.

In one possible implementation, the neutron proxy node may be a proxy node of a control node or a proxy node of a compute node.

In practical application, the neutron proxy node can be a proxy node of the control node, and the proxy control node realizes corresponding functions; the neutron proxy node can also be a proxy node of the computing node, and the proxy computing node realizes corresponding functions.

In an example, as shown in fig. 2a, the control node includes a main service node (a neutron-server as shown in the figure and may also be understood as a service process) and a plurality of proxy nodes, where the neutron-server is used to provide an OpenStack network API to the outside, receive a network request, call a plugin processing request, and so on, and for example, the neutron-server is tasked with receiving a restful request and distributing the processing. The proxy node of the control node may include a neutron-dhcp-agent, neutron-l3-agent, neutron-metadata-agent, neutron-openvswitch-agent.

The Neutron proxy node can also be a proxy node of the computing node, and the proxy computing node realizes corresponding functions. As shown in fig. 2b, the proxy node of the compute node may include a neutron-openvswitch agent for managing the virtual switches of the neutron. The agent nodes of the control node and the neutron agent nodes of the computing node are respectively provided with a pre-configured configuration updating subsystem, and the pre-configured configuration updating subsystem is used for updating the configuration information of each node.

The specific manner of determining the configuration update request corresponding to the proxy node may be implemented by the following embodiments.

In one possible implementation manner, the first restful request carries a node identifier of a neutron proxy node, and the configuration update request is determined by the control node through the following ways:

In practical application, the control node receives the restful request through the neutron server process, analyzes the first restful request, and can obtain each node identifier and a configuration update request corresponding to each node identifier based on an analysis result. The configuration update request may be directed to a server process of the control node, or may be directed to a proxy node of the control node or a proxy node of the computing node, if directed to the server process of the control node, the control node performs corresponding processing, and if directed to the proxy node of the control node or the computing node, the control node may send the configuration update request to the corresponding proxy node according to the node identifier. Specifically, if the Restful request received by the control node carries the node identifier of the neutron proxy node, the Restful request includes a configuration update request for the neutron proxy node corresponding to the node identifier, and the control node may send the corresponding configuration update request to the corresponding neutron proxy node, so that the neutron proxy node updates configuration information based on the received configuration update request.

The above embodiments of the present application are implementation methods using a neutron proxy node as an execution body, and the method in the present application may also use a control node as an execution body, where specific implementation methods are described in the following embodiments.

In one possible implementation manner, the execution body of the method is a control node, and acquiring the configuration update request includes at least one of the following:

In practical application, the control node can determine the configuration update request through the received second Restful request, specifically, the server process of the control node receives the second Restful request through the HTTP network, and determines the configuration update request according to the second Restful request. In addition, the configuration update request may be a command line request directly input by a user in the form of an input command, whether the control node or the neutron proxy node, a thread may be newly created, and the configuration update request in the form of a command line is obtained by monitoring the corresponding Unix socket file in the thread.

In addition, the configuration update request in the second Unix socket file is obtained by:

in one possible implementation, the method further includes:

In practical application, the control node receives a configuration update request in the form of a command line, and writes the configuration update request into the Unix socket file. The Unix socket file is a local file, and communication between different processes can be realized through the Unix socket file. The Unix socket only performs data copying, and does not perform complex operations such as adding and deleting message heads, calculating checksums, calculating message sequences and the like which need to be processed in a network protocol stack, so that the Unix socket is used for communication between different processes of the same computer, and the operation is simple and efficient.

The specific manner of determining the configuration update request corresponding to the control node may be implemented by the following embodiments.

In one possible implementation manner, the second Restful request carries a node identifier of the control node, and the obtaining the configuration update request based on the second Restful request includes:

and determining the configuration update request corresponding to the node identifier of the control node in the node identifiers as the configuration update request.

In practical application, the second Restful request received by the control node carries the node identifier of the control node, the control node receives the second Restful request through a server process, analyzes the second Restful request, and can obtain each node identifier and the configuration update request corresponding to each node identifier based on the analysis result. And determining the configuration update request corresponding to the node identifier of the control node in the node identifiers as the configuration update request. The configuration update request corresponding to the node identification of the control node is a configuration update request for a server process of the control node.

The implementation of receiving a configuration update request via a restful request is described below in one particular embodiment.

In an example, a schematic diagram of a control node determining a configuration update request via a restful request is shown in fig. 3. The control node adds an API for dynamically modifying configuration in a server process (a neutron-server shown in the figure), a Web server in the server process receives a restful request through the API, analyzes the restful request, obtains each node identifier and a configuration update request corresponding to each node identifier, determines a sending path of the configuration update request according to the node identifier, transmits the path to a route map, configures a corresponding route processing function, directly sends the configuration update request to a control node own configuration update subsystem for processing if the configuration update request is for the server process of the control node, and sends the configuration update request to a corresponding proxy node (a neutron-optional-agent, neutron-dhcp-agent shown in the figure) through a remote procedure call (Remote Procedure Call, RPC) through a server (a Rabbmq) of an advanced message queue protocol if the configuration update request is for the proxy node or a proxy node of a computing node.

The implementation of determining a configuration update request by a request in the form of a command line is described below in one particular embodiment.

In an example, a schematic diagram of determining a configuration update request by monitoring a socket file is shown in fig. 4, a command line interface client (Cli client shown in the figure) receives a command line request input by a user, and a neutron service shown in the figure includes: the server processes in the control nodes, the proxy nodes of the control nodes, and the proxy nodes of the computing nodes may each include a Unix socket monitoring module (shown as Unix socket monitoring) and a configuration update subsystem. After receiving the command line request, writing a local Unix socket Sock file, and each node acquires a configuration update request in the form of the command line by monitoring the form of the Sock file and sends the configuration line request to a configuration update subsystem for corresponding processing.

Step S103, determining configuration information modification functions corresponding to the target configuration items respectively;

the configuration information modification function is a function for modifying the configuration information of each configuration item, and the configuration information modification function may be a section of program statement for modifying the field value of the configuration item in the configuration file, or may be a function for creating a new thread, or a function for closing a thread, etc., which is not limited in this application.

Before the configuration information updating request corresponding to each node is obtained, the configuration items in each node and the information related to the configuration items need to be registered, and after the registration, the corresponding nodes can be updated according to the configuration information updating request.

In this embodiment, the configuration update request is obtained before the configuration update request is received, and when each node is started, the configuration information related to each node may be registered in the configuration update subsystem, and the registration of the configuration information is implemented by setting the configuration item and the corresponding configuration information modification function. Receiving a configuration item setting request, wherein the request comprises at least one updatable configuration item identifier and configuration information modification functions corresponding to each updatable configuration item, establishing a mapping relation between each updatable configuration item identifier and the corresponding configuration information modification function, storing, after registration, enabling a configuration update subsystem to respond when receiving the configuration update request, determining the configuration information modification function corresponding to the identifier of the target configuration item based on the identifier of each updatable configuration item and the mapping relation between the configuration information modification functions corresponding to each updatable configuration item, and correspondingly updating the configuration information of the updatable configuration item.

In practical application, after receiving a configuration item setting request, according to the identifier of each updatable configuration item, the current configuration information of each updatable configuration item can be obtained, and a single object is adopted to globally store the identifier of each updatable configuration item and the corresponding current configuration information, where the single object may be in the form of a key value pair, for example, the configuration items of a general program are all in the form of a key value pair similar to "key=value", the keys in the key value pair are the identifiers of the updatable configuration items, the values are the current configuration information of the updatable configuration items, for example, "pool_size=5", and indicate that the number of threads in a thread pool is 5, where pool_size is a key, that is, the key of the updatable configuration item, and 5 is a value, that is, the current configuration information of each updated configuration item. When registering the configuration item, the value of the key is registered, and the value of the key of the configuration item associated with each node is registered to the configuration updating subsystem.

When registering, the configuration item is globally saved in the memory through the single-instance object, for example, the single-instance object can save the key value pair corresponding to the configuration item through a field or hash function hash. In the embodiment of the application, the configuration items are saved by adopting the single-instance object, so that repeated creation of the configuration items can be avoided, the system overhead caused by repeated creation of the configuration items is reduced, and the memory is saved.

Because the functions of the nodes of the neutron component are different, the required configuration information is also different, the configuration information associated with each node of the neutron component is required to be registered by analyzing the original configuration file of the neutron component, and the configuration information registration process is described below through a specific embodiment.

As shown in fig. 5, the configuration items of each node, i.e., the node-server, neutron-dhcp-agent, neutron-openvswitch-agent, and the corresponding configuration information modification function are respectively registered, the configuration files in the figure respectively represent the configuration items corresponding to each node and the configuration information modification function (i.e., the configuration related to the node-server, the configuration related to the node-dhcp-agent, the configuration related to the node-openvswitch-agent, and the configuration update subsystem of each node may include a configuration registration module (configuration registration shown in the figure), a configuration key matching module (configuration key matching shown in the figure), and a configuration processing module (configuration processing shown in the figure), where the configuration registration module corresponding to each node is used to register the configuration related to the node-server, the configuration related to the node-dhcp-agent, and the configuration related to the node-openvswitch-agent, respectively. When the configuration updating subsystem receives a configuration updating request, a configuration key matching module is used for matching the value of the key of the configuration item analyzed in the configuration updating request with the value of the key of the configuration item registered in the configuration registration module for each node, and the configuration item successfully matched and the configuration information modification function corresponding to the configuration item are sent to a configuration processing module; the configuration processing module is used for modifying the current configuration information of the configuration item into new configuration information by utilizing the configuration information modification function corresponding to the configuration item.

Step S104, updating the current configuration information of each target configuration item into new configuration information through callback of the corresponding configuration information modification function of each target configuration item.

Specifically, a configuration information modification function corresponding to the configuration item to be updated can be called in a callback mode, and the current configuration information of the configuration item to be updated is updated into new configuration information by utilizing the modification function.

The new configuration information of the target configuration item is different, and the implementation manner of updating the target configuration item by using the configuration information modification function is different, which is specifically described in the following embodiments.

a key value modification function;

a key value modification function and a configuration item processing function;

In practical application, the configuration information modification function may include a key value modification function, or a key value modification function and a configuration item processing function, when registering the configuration items, a corresponding configuration information modification function is configured for each configuration item, some configuration information modification functions of the configuration items are key value modification functions, and some configuration information modification functions of the configuration items are key value modification functions and configuration item processing functions. Wherein the configuration item processing function is a function for performing corresponding processing on the configuration item, for example, a thread creation function and the like. If the configuration information of the target configuration item is updated according to the value in the key value pair of the target configuration item, that is, the value in the key value pair corresponding to the target configuration item is modified, the configuration update of the target configuration item can be realized, then a key value modification function corresponding to the target configuration item is called, the value in the key value pair of the single object storing the target configuration item is modified, and the value in the key value pair is modified from the current configuration information to the new configuration information.

If the updating of the target configuration item needs to modify both the key value pair and the corresponding function by callback, for example, modifying the number of the working threads corresponding to the configuration item, the key value modifying function corresponding to the target configuration item and the configuration item processing function of the target configuration item are called in a callback mode, the target configuration item is modified by using the key value modifying function, and corresponding processing is performed by using the configuration item processing function, for example, a new working thread is created by a thread creating function, and some working threads are closed by using a thread closing function. In addition to the modification of the worker thread, updating the target configuration item by calling back other functions may be included, which is not limited in this application.

In an example, the current configuration information of the target configuration item is "pool_size=5", the new configuration information is "pool_size=10", then the key value modifying function is called in a callback manner, the original "pool_size=5" is modified to "pool_size=10", and then the thread creating function for creating new threads is called to create 5 new working threads.

In yet another example, the current configuration information of the target configuration item is "pool_size=5", the new configuration information is "pool_size=3", and then the "pool_size=5" is changed to "pool_size=3" by the callback key value modification function; for two threads which are about to finish work at present, no new work is redistributed, a thread closing function is called in a callback mode, and the two threads are closed when the two threads finish work.

The specific operation of the various modules in the configuration update subsystem is described below with respect to a specific embodiment.

As shown in fig. 6, a configuration analysis module (configuration analysis shown in the figure) in the configuration updating subsystem analyzes a configuration updating request obtained from a restful api or a socket monitoring module, obtains each target configuration item to be updated and new configuration information of each target configuration item, and sends the configuration updating request to a configuration matching module (configuration matching shown in the figure); each configuration item which needs to be dynamically updated and a configuration information modification function corresponding to each configuration item are registered in the configuration registration module (configuration registration shown in the figure) in advance; the configuration matching module matches each target configuration item with the configuration items registered in the configuration registration module, and takes the configuration information modification function of each successfully matched configuration item as the configuration information modification function corresponding to each corresponding target configuration item; the memory application module (memory application shown in the figure) calls the configuration information modification function corresponding to each target configuration item in a callback mode, modifies the current configuration information of the target configuration item by using the configuration information modification function, and applies the new configuration information of each target configuration item to be updated to the memory. The configuration information modification function corresponding to each callback is different, taking 3 callbacks as examples (such as callback 1, callback 2 and callback 3 shown in the figure), each callback calls one configuration information modification function, and the current configuration information in the target configuration item is modified into new configuration information by utilizing each configuration information modification function.

The configuration information updating method provided by the embodiment of the application comprises the steps of firstly obtaining a configuration updating request; analyzing the configuration update request to obtain update configuration information, wherein the update configuration information comprises the identification of each target configuration item to be updated and new configuration information of each target configuration item; determining configuration information modification functions corresponding to the target configuration items respectively; and updating the current configuration information of each target configuration item into new configuration information by calling back the configuration information modification function corresponding to each target configuration item. According to the technical scheme, when the configuration updating is carried out on the neutron service component, the current configuration information is updated to the new configuration information by calling back the configuration information modification function corresponding to the target configuration item, the neutron service component does not need to be restarted, the problem of network paralysis of the virtual machine caused by the restarting is avoided, the normal operation of the neutron service component is not influenced, and the stability of the system is improved.

In step S203, if the node identifier includes an identifier of the neutron proxy node, a configuration update request is sent to the corresponding neutron proxy node, so that the neutron proxy node determines, according to the received configuration update request, a configuration information modification function corresponding to each target configuration item in the configuration update request, and updates the current configuration information of each target configuration item to new configuration information by calling back the configuration information modification function corresponding to each target configuration item.

If the node identification includes the identification of the neutron proxy node, the configuration update request is indicated to be for the proxy node, wherein the proxy node can include a proxy node of a control node or a proxy node of a calculation node, the control node sends the configuration update request to the corresponding proxy node according to the identification of the proxy node, the proxy node determines a configuration information modification function corresponding to each target configuration item in the configuration update request, and updates the current configuration information of each target configuration item into new configuration information by calling back the configuration information modification function corresponding to each target configuration item.
