Description

Technical Field

[0001] The present invention relates to the technical field of multi-host automated operation and maintenance, and in particular to a multi-host automated operation and maintenance control method and system based on the Ansible framework. Background Art

[0002] Automated operations and maintenance can help enterprises effectively manage and run IT systems. In the early stages of development, enterprises used scripts and simple programs to automate IT operations and maintenance tasks. With the development of technology, automated operations and maintenance tools have become more complex and can achieve more functions, such as automated deployment, automated monitoring, automated orchestration, etc. Now, automated operations and maintenance have become an important part of enterprise IT management, which can help enterprises manage and run IT systems more effectively. Ansible is an automated operations and maintenance tool developed in Python. It can perform tasks such as batch system configuration, batch program deployment, batch command execution, etc. It can also deploy software and orchestrate more advanced IT tasks. The main goal of Ansible is simplicity and ease of use. Ansible itself is an execution framework, and it is its many modules that actually perform operations and maintenance tasks. Ansible can be used to manage large-scale operations and maintenance environments in batches.

[0003] When faced with the need for multi-host automated operation and maintenance control, the existing operation and maintenance task execution based on the Ansible framework has the following limitations: (1) In the case of multi-host automated operation and maintenance control, different hosts may execute the same operation and maintenance task at different times (the main reason is that different hosts have different progress in executing tasks, resulting in different time points for executing the same operation and maintenance task at different times). In this case, the control node cannot distribute the operation and maintenance scripts according to a unified time; (2) Usually, the communication efficiency between different hosts and the control node will be affected by factors such as communication bandwidth and communication link occupancy, resulting in differences in communication efficiency. When distributing operation and maintenance task scripts, it is necessary not only to ensure that each operation and maintenance The task script is distributed to the host before the operation and maintenance task is executed. It is also necessary to ensure that the communication efficiency during distribution meets the requirements and that the host's script storage space can receive but not execute the operation and maintenance script data. This brings planning difficulties to the operation and maintenance script distribution control in the scenario of multi-host automated operation and maintenance control requirements; (3) Since the operation and maintenance script will be updated from time to time, it will be distributed to the host by the control node after the update. If the operation and maintenance script is saved on the host for a long time without updating, the stability, effectiveness and success rate of the host's execution of the operation and maintenance task will not be guaranteed. When planning the operation and maintenance script distribution under the requirements of multi-host automated operation and maintenance control, it is also necessary to consider the update optimization problem of the operation and maintenance script, which further increases the difficulty of operation and maintenance management.

[0004] Therefore, how to achieve scientific planning and reasonable execution of operation and maintenance script distribution, management, update and operation control in the scenario of multi-host automated operation and maintenance control, improve the stability of operation and maintenance tasks of enterprise multi-host automated operation and maintenance, and improve the effectiveness of enterprise management and operation of IT systems is a technical problem that needs to be solved urgently.

[0043] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] The embodiment of the present invention provides a multi-host automated operation and maintenance control method based on the Ansible framework, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the multi-host automated operation and maintenance control method based on the Ansible framework of the present invention.

[0045] In this embodiment, a multi-host automated operation and maintenance control method based on the Ansible framework includes the following steps:

[0046] S100: Obtaining task execution progress information of a plurality of host nodes within a target operation and maintenance range during a target operation and maintenance control period; wherein the task execution progress information includes a time period for each host node to execute each operation and maintenance task during the target operation and maintenance control period;

[0047] S200: parsing the task execution progress information, extracting the operation and maintenance task types and operation and maintenance task execution times for each host node in the target operation and maintenance control period, constructing the execution requirements of the operation and maintenance scripts corresponding to each operation and maintenance task type, and generating a list of operation and maintenance script execution requirements for the target operation and maintenance control period;

[0048] S300: Querying communication efficiency parameters and communication access quantity limits for each minimum operation and maintenance communication cycle between a plurality of host nodes and a control node deployed with Ansible within a target operation and maintenance control period, taking into account script storage reserved space of the plurality of host nodes, using communication efficiency, communication access quantity limits, and communication storage space as constraint conditions, and using script quality determined by script update time as an optimization objective, to optimize and solve the automated operation and maintenance strategy between the control node and the plurality of host nodes within the target operation and maintenance control period;

[0049] S400: Based on the script distribution policy in the automated operation and maintenance policy, driving the control node to distribute the script to the corresponding host node at a corresponding time point, and based on the script retention policy in the automated operation and maintenance policy, driving the host node to perform script management of the storage space;

[0050] S500: Each host node calls the operation and maintenance script stored in the storage space according to the script execution schedule to execute the operation and maintenance task corresponding to the operation and maintenance script.

[0051] It should be noted that in the scenario of multi-host automated operation and maintenance control, the existing operation and maintenance task execution based on the Ansible framework has the following limitations: (1) In the case of multi-host automated operation and maintenance control, different hosts may execute the same operation and maintenance task at different times (the main reason is that different hosts have different progress in executing tasks, resulting in different time points for executing the same operation and maintenance task at different times). In this case, the control node cannot distribute the operation and maintenance scripts according to the unified time; (2) Usually, the communication efficiency between different hosts and the control node will be affected by factors such as communication bandwidth and communication link occupancy, resulting in differences in communication efficiency. When distributing operation and maintenance task scripts, it is necessary not only to ensure Each operation and maintenance task script is distributed to the host before the operation and maintenance task is executed. It is also necessary to ensure that the communication efficiency during distribution meets the requirements and that the host's script storage space can receive but not execute the operation and maintenance script data. This brings planning difficulties to the operation and maintenance script distribution control in the scenario of multi-host automated operation and maintenance control requirements; (3) Since the operation and maintenance script will be updated from time to time, it will be distributed to the host by the control node after the update. If the operation and maintenance script is saved on the host for a long time without updating, the stability, effectiveness and success rate of the host's execution of the operation and maintenance task will not be guaranteed. When planning the operation and maintenance script distribution under the requirements of multi-host automated operation and maintenance control, it is also necessary to consider the update optimization problem of the operation and maintenance script, which further increases the difficulty of operation and maintenance management.

[0052] In order to solve the above problems, this embodiment constructs the execution requirements of the operation and maintenance scripts corresponding to each operation and maintenance task type and generates an operation and maintenance script execution requirement list for the target operation and maintenance control period. Based on the communication efficiency parameters and communication access quantity restrictions between the control node and the host node in each minimum operation and maintenance communication cycle, the script storage reserved space of several host nodes is considered, and the control node is driven to execute the automatic distribution of the operation and maintenance scripts and the host node is driven to realize the intelligent management and automatic execution of the script storage in the storage space. The scientific planning and reasonable execution of the operation and maintenance script distribution, management, update and operation control under the multi-host automated operation and maintenance control demand scenario are realized, the stability of the operation and maintenance tasks of the enterprise's multi-host automated operation and maintenance is improved, and the effectiveness of the enterprise's management and operation of IT systems is improved.

[0055] S120: Determine task running progress information of a plurality of host nodes within a target operation and maintenance scope in a target operation and maintenance control period according to a time period for executing each operation and maintenance task in the task running plan.

[0056] In this embodiment, the task execution progress information of each host node is obtained from the task execution plan information sent by each host node during each task execution progress reporting cycle. In actual application, the time interval between two adjacent task execution progress reporting cycles of each host node is configured to be the same and no less than the standard duration of each operation and maintenance control period.

[0057] In a preferred embodiment, the task execution progress information is parsed to extract the type of operation and maintenance tasks and the execution time steps of the operation and maintenance tasks executed by each host node in the target operation and maintenance control period, specifically including:

[0059] S220: Based on the task description information, extract task keywords for each operation and maintenance task using a natural language processing tool, and match the operation and maintenance task type of each operation and maintenance task using a mapping relationship between the task keywords, the operation and maintenance task type, and the task keyword set;

[0060] S230: Determine the execution time of the operation and maintenance task executed by each host node in the target operation and maintenance control period according to the time period during which each operation and maintenance task corresponds to each host node in the target operation and maintenance control period.

[0063] S250: Summarize the execution requirements of each host in the target operation and maintenance control period separately to generate an operation and maintenance script execution requirement list for the target operation and maintenance control period.

[0064] In this embodiment, after obtaining the task execution progress information, the task execution progress information is parsed, the task description information is processed using natural language processing tools, and the operation and maintenance scripts are matched through the operation and maintenance script pairing library. Finally, the execution requirements of each host in the target operation and maintenance control period are separately summarized to generate a list of operation and maintenance script execution requirements for the target operation and maintenance control period.
