Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A cloud server (also referred to as a cloud host) is typically a service process running on a physical server, which may be referred to as a host of the cloud server, and the host may provide an image for the cloud server, and the image is typically a well-made operating system, such as a Linux operating system or a Windows operating system.
Because the cloud servers running on the hosts are frequently increased or released, and the images used by the cloud servers released on the hosts and the cloud servers running on the hosts are all reserved in the designated positions of the hosts, a large amount of image resources can be left in the designated positions of the hosts. When the mirror image resources reserved at the designated position reach a certain threshold value, the cloud server cannot be dispatched to the host machine to operate, at the moment, a person in charge of manually logging in the host machine is required, the mirror images (equivalent to useless mirror images) which need to be cleaned on the host machine are screened, then the mirror images which need to be cleaned are manually deleted, and only when the cloud server cannot operate, the mirror images can be manually cleaned in the mode, so that the normal operation of the cloud server is influenced, and the efficiency of manually cleaning the mirror images is low.
Based on the above problems, embodiments of the present invention provide a method and an apparatus for cleaning mirror image data, and an electronic device. To facilitate understanding of the embodiment, first, a detailed description is given to a method for cleaning mirror image data disclosed in the embodiment of the present invention, where the method is applied to a monitoring device, and a monitoring platform is deployed on the monitoring device, where the monitoring platform may be a Zabbix monitoring platform or other monitoring platforms. The Zabbix monitoring platform is generally an enterprise-level open source solution providing distributed system monitoring and network monitoring functions based on a WEB interface, and can monitor various network parameters, ensure the safe operation of a server system, and provide a flexible notification mechanism to enable a system administrator to quickly locate and solve various problems.
As shown in fig. 1, the method comprises the steps of:
step S102, monitoring the occupation amount of a storage space of mirror image data in a physical server; the mirror image data is operating system resource data of the virtual cloud server.
The physical server is usually a stand-alone server, that is, a physically separate server, and the physical server is configured to include a processor, a hard disk, a memory, a system bus, and the like, and is similar to a general computer architecture, but needs to provide highly reliable services, and thus has high requirements on processing capability, stability, reliability, security, scalability, manageability, and the like. The physical server is a host of a virtual cloud server (corresponding to the cloud server) operating on the physical server.
In specific implementation, a storage space for storing mirror image data is preset in the physical server, the mirror image data used by the virtual cloud server released from the physical server and the mirror image data used by the virtual cloud server running in the physical server are stored in the storage space, and the mirror image data is operating system resource data of the virtual cloud server running on the physical server. In a specific implementation, each virtual cloud server needs to download the image data before running, and the storage space may also be understood as a space in the physical server for the virtual cloud server to provide the downloaded image data. The mirror image data used by each virtual cloud server occupies a certain space of the storage space, but the size of the storage space is fixed, so in order to ensure normal use of the storage space, the monitoring device is required to monitor the occupied amount of the storage space in real time (which is equivalent to the occupied amount of the storage space).
And step S104, if the occupied storage space of the mirror image data reaches a preset occupied storage space threshold, sending a data cleaning instruction to the physical server so as to clean at least one part of mirror image data in the physical server through the physical server.
The occupancy threshold is a value set by a user according to the monitoring requirement, and the value may be 90% of the storage space, may be 10G, and the like. When the monitoring device monitors that the occupied amount of the storage space of the mirror image data reaches the occupied amount threshold, a data cleaning instruction is sent to the physical server, and after the physical server receives the data cleaning instruction, useless mirror image data can be automatically searched from the storage space, and useless mirror image data are deleted, wherein the useless mirror image data are mirror image data which are stored in the storage space and are not used by a currently running virtual cloud server.
The method for cleaning the mirror image data provided by the embodiment of the invention comprises the steps of monitoring the occupancy amount of a storage space of the mirror image data in a physical server through a preset monitoring device, wherein the mirror image data is the resource data of an operating system of a virtual cloud server; and if the occupied storage space of the mirror image data reaches a preset occupied storage space threshold, sending a data cleaning instruction to the physical server so as to clean at least one part of mirror image data in the physical server through the physical server. The method can monitor the occupation amount of the storage space of the mirror image data in the physical server in real time, and automatically sends the data cleaning instruction when the occupation threshold is reached, so that the physical server receiving the data cleaning instruction automatically cleans useless mirror image data in the storage space, and compared with a method for manually screening and deleting useless mirror image data in the storage space, the method improves the efficiency of cleaning the mirror image data; meanwhile, the occupied amount of the storage space can be monitored in real time and the cleaning instruction can be automatically triggered in the mode, so that the mirror image data does not need to be cleaned when the virtual cloud server cannot run, and the normal running of the virtual cloud server is ensured.
The embodiment of the invention also provides another method for cleaning the mirror image data, which is realized on the basis of the method of the embodiment; as shown in fig. 2, the method comprises the steps of:
step S202, monitoring the occupation amount of a storage space of mirror image data in a physical server; the mirror image data is operating system resource data of the virtual cloud server.
Step S204, if the occupation amount of the storage space of the mirror image data reaches a preset occupation amount threshold value, sending alarm information to a specified object, and sending a data cleaning instruction to a physical server so as to clean at least a part of mirror image data in the physical server through the physical server.
The specified object can be a preset data cleaning responsible person; the alarm information is used for indicating: the occupied storage space of the mirror image data in the physical server reaches a preset occupied amount threshold, and at least a part of the mirror image data in the physical server is to be cleaned. During specific implementation, an alarm mail storing alarm information or a short message storing the alarm information can be sent to a mailbox of a responsible person through a preset communication platform (for example, onepiece) so as to remind the responsible person that the occupied amount of the storage space of the mirror image data in the server reaches the occupied amount threshold value and useless mirror image data in the storage space is about to be cleaned.
Step S206, if the cleaning completion information returned by the physical server is received, a message of successful cleaning and the current storage space occupation amount of the mirror image data in the physical server are sent to the specified object.
After the physical server finishes cleaning useless mirror image data in the storage space, cleaning finishing information is returned to the monitoring equipment, so that the monitoring equipment sends a message of successful cleaning and the current occupation amount of the storage space in the physical server to the specified object, the specified object is informed that the useless mirror image data in the physical server is cleaned completely, and the specified object can fully know the current state of the physical server.
The method for cleaning the mirror image data comprises the steps of firstly monitoring the occupation amount of a storage space of the mirror image data in a physical server; if the occupation amount of the storage space of the mirror image data reaches a preset occupation amount threshold value, sending alarm information to a specified object and sending a data cleaning instruction to a physical server so as to clean at least one part of mirror image data in the physical server through the physical server; and if the cleaning completion information returned by the physical server is received, sending a successful cleaning message and the current occupied storage space of the mirror image data in the physical server to the specified object. The method monitors the occupation amount of the storage space in the physical server in real time, and automatically clears useless mirror image data in the physical server when the occupation amount of the storage space reaches the occupation amount threshold value, so that the effect of processing the mirror image data at a high rate and quickly is achieved.
The embodiment of the invention also provides another method for cleaning mirror image data, which is applied to a physical server and comprises the following specific steps as shown in fig. 3:
step S302, if a data cleaning instruction is received, mirror image data used by the currently running virtual cloud server and mirror image data stored in a preset storage space are inquired.
The data clearing instruction is sent when the preset monitoring device monitors that the occupancy of the storage space reaches a preset occupancy threshold. The storage space is a space preset in the physical server and used for storing mirror image data, the mirror image data used by the virtual cloud server released from the physical server and the mirror image data used by the virtual cloud server running in the physical server are stored in the storage space, and the mirror image data is operating system resource data of the virtual cloud server. The currently running virtual cloud server is a running virtual cloud server in the physical servers.
Step S304, determining data to be cleaned based on the mirror image data used by the currently running virtual cloud server and the mirror image data stored in the storage space.
The mirror image data stored in the storage space comprises the mirror image data used by the currently running virtual cloud server and the released mirror image data used by the virtual cloud server, so that the mirror image data stored in the storage space can be screened based on the mirror image data used by the currently running virtual cloud server to obtain the data to be cleaned, namely the released mirror image data used by the virtual cloud server.
And step S306, deleting the determined data to be cleaned.
In the method for cleaning the mirror image data, when a data cleaning instruction is received, the mirror image data used by the currently running virtual cloud server and the mirror image data stored in a preset storage space are inquired; determining data to be cleaned based on the mirror image data used by the currently running virtual cloud server and the mirror image data stored in the storage space; and then deleting the determined data to be cleaned. According to the method, when the data cleaning instruction is received, the physical server automatically screens the data to be cleaned and deletes the data to be cleaned, the mirror image data in the physical server does not need to be manually screened and cleaned, and the cleaning efficiency of the mirror image data is improved.
The embodiment of the invention also provides another method for cleaning the mirror image data, which is realized on the basis of the method of the embodiment; the method mainly describes a specific process of inquiring mirror image data used by a currently running virtual cloud server and mirror image data stored in a preset storage space (realized through the following steps S402-S404), and a specific process of determining data to be cleaned based on the mirror image data used by the currently running virtual cloud server and the mirror image data stored in the storage space (realized through the following step S406); as shown in fig. 4, the method includes the steps of:
step S402, if a data cleaning instruction is received, a preset interface is called, and mirror image data used by the currently running virtual cloud server is inquired.
The preset interface can check mirror image data used by a currently running virtual cloud server on the physical server. In a specific implementation, the preset interface may be a Nova interface, which is generally a computing organization controller in the OpenStack cloud, supports all activities of a life cycle of an instance in the OpenStack cloud, and is also generally a platform responsible for managing computing resources, networks, authentication, and required extensibility.
Step S404, querying a mirror image use list under the specified path address, and determining mirror image data in the mirror image use list as mirror image data stored in the storage space.
In a specific implementation, the mirror data stored in the storage space includes: mirror image data in a mirror image using list stored under the specified path address; the mirror image data stored in the storage space is as follows: mirror data used by a virtual cloud server running at a historical time (equivalent to the released virtual cloud server), and mirror data used by a currently running virtual cloud server. The specified path address is usually a directory address set by the user according to the user's own needs, for example, the directory address may be/vm _ data/openstack/nova/instance/_ base/. The mirror image use list is a list for storing mirror image data under the appointed path address.
Step S406, determining, from the mirror image data stored in the storage space, mirror image data other than the mirror image data used by the currently running virtual cloud server as data to be cleaned.
The mirror image data used by the currently running virtual cloud server is necessary mirror image data and cannot be deleted; the mirror image data used by the virtual cloud server running at the historical moment is useless mirror image data and needs to be cleaned, so that the mirror image data except the mirror image data used by the currently running virtual cloud server can be screened out from the mirror image data stored in the storage space, and the screened mirror image data is used as the data to be cleaned.
And step S408, deleting the determined data to be cleaned.
And step S410, sending cleaning completion information to preset monitoring equipment so as to send a successful cleaning message and the current occupied amount of the storage space to the specified object through the preset monitoring equipment.
After the physical server finishes cleaning the data to be cleaned in the storage space, cleaning completion information is returned to the preset monitoring equipment, so that the preset monitoring equipment sends a message of successful cleaning and the current occupied amount of the storage space in the physical server to the specified object, the specified object is informed that the data to be cleaned in the physical server is cleaned completely, and the specified object can fully know the current state of the physical server.
In some embodiments, a mirror image data cleaning script runs in the physical server, a monitoring device is preset to monitor the occupation amount of a storage space of mirror image data in the physical server in real time, when the occupation amount of the storage space is monitored to reach an occupation amount threshold, warning information is sent to a specified object, and a data cleaning instruction is sent to the physical server to trigger the mirror image data cleaning script; after the mirror image data cleaning script is triggered, the data to be cleaned in the storage space can be automatically cleaned, namely: calling a preset interface to check the mirror image data used by the currently running virtual cloud server in the physical server and the mirror image data stored in the storage space, determining the mirror image data except the mirror image data used by the currently running virtual cloud server from the mirror image data stored in the storage space as data to be cleaned, executing file deletion operation, and deleting the data to be cleaned; after the deletion is completed, the mirror image data cleaning script returns cleaning completion information to the preset monitoring equipment, and after the preset monitoring equipment receives the cleaning completion information, the preset monitoring equipment sends a successful cleaning message and the current occupation amount of the storage space to the specified object.
According to the method for cleaning the mirror image data, if a data cleaning instruction is received, a preset interface is called, the mirror image data used by the currently running virtual cloud server is inquired, and the mirror image data in the mirror image using list under the specified path address is determined as the mirror image data stored in the storage space; determining mirror image data except for mirror image data used by a currently running virtual cloud server from the mirror image data stored in the storage space as data to be cleaned; deleting the determined data to be cleaned; and after the deletion is finished, sending cleaning finishing information to the preset monitoring equipment so as to send a successful cleaning message and the current occupied amount of the storage space to the specified object through the preset monitoring equipment. According to the method, the occupied amount of the storage space in the physical server is automatically monitored through the preset monitoring equipment, and when the occupied amount of the storage space reaches the occupied amount threshold value, a data cleaning instruction is sent to the physical server, so that the physical server can quickly clean the data to be cleaned, the cleaning efficiency of mirror image data is improved, the personnel investment is reduced, and the utilization rate of environmental resources can be improved; meanwhile, the cleaning mode can predict the problems in advance and automatically process the problems, so that the normal operation of the virtual cloud server is ensured.
