Detailed Description
The core of the application is to provide an IP modification method of the cluster system, which can realize quick and efficient IP modification on the original data of the cluster system while effectively retaining the original data of the cluster system; another core of the present application is to provide an IP modification apparatus, device and computer-readable storage medium for a cluster system, which also have the above beneficial effects.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. 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 application.
The embodiment of the application provides an IP modification method of a cluster system.
Referring to fig. 1, fig. 1 is a schematic flowchart of an IP modification method of a cluster system provided in the present application, where the IP modification method of the cluster system may include:
s101: traversing cluster components in a cluster system to generate an original global configuration file;
the step aims to realize the acquisition of an original global configuration file, wherein the original global configuration file is the global configuration file of each cluster component in the cluster system before the IP information is not modified, so that the IP modification of the cluster system can be realized by modifying the IP information in the global configuration file subsequently. Specifically, each cluster component in the current cluster system may be traversed first, and a corresponding original global configuration file may be generated based on a traversal result. Further, the method can also be saved in a corresponding file for subsequent use.
It is understood that the type of the cluster system does not affect the implementation of the present technical solution, and for example, the cluster system may be a K8S cluster, a database cluster, a file management cluster, and the like, which is not limited in this application. In addition, the cluster component refers to various components in the cluster system, such as various certificates, various server components, and the like, and the specific type of the cluster component can be determined by the structure of the cluster system.
S102: modifying the original global configuration file by using a preset IP modification list to obtain a new global configuration file;
the step aims to modify the original global configuration file, namely, a new global configuration file is obtained by modifying the IP information in the original global configuration file. Specifically, an IP modification list may be created in advance to obtain the preset IP modification list, and then the specific content that needs to be modified in the original global configuration file is determined by using the preset IP modification request and is modified, so that a new modified global configuration file can be obtained.
The preset IP modification list is created by a technician according to actual needs, and related information of various cluster components to be modified in the cluster system, such as names, types, original IPs, and the like of the cluster components, and modified IP information of the cluster components are set, so as to implement IP modification. For example, taking the K8S cluster system as an example, a corresponding preset IP modification list may include: settings modify K8S global configuration files, cluster/etc/hosts information,/etc/etcd. env information,/root/. kube/file information, and/etc/kubernets file information.
S103: and regenerating each cluster component according to the new global configuration file, and restarting each cluster component service.
The step aims to realize regeneration and restart of the cluster components in the cluster system. Specifically, after a new global configuration file is obtained, since the new global configuration file is the global configuration file after IP information is modified, the cluster component corresponding to the new global configuration file can be regenerated, and obviously, the regenerated cluster component is the cluster component with new IP information after IP information is modified; and further, restarting each cluster component in the cluster system, so that each cluster component realizes self-adaptive adjustment and restores to a normal working state, thereby completing IP modification of the cluster system.
Therefore, the IP modification method for the cluster system provided by the application establishes an IP modification list in advance for the cluster system, that is, sets the relevant information of the cluster component that needs to be subjected to IP modification according to the actual requirement, so that after an initial global configuration file (that is, the original global configuration file) of the cluster system is obtained through traversal of the cluster component, the original global configuration file can be modified directly by using a preset IP modification list, so as to generate a new global configuration file, so that the cluster component can be regenerated by using the new global configuration file, and the cluster component can be adaptively adjusted and restored to a normal working state by restarting, so that the IP modification of the cluster system is realized. Obviously, the implementation mode does not need to uninstall and reinstall the cluster system, original data and operation in the cluster system can be reserved, the IP modification efficiency in the cluster system is effectively improved, the method can perfectly adapt to practical application scenes such as user machine room relocation, server relocation, data service migration and network planning change, and huge economic value is brought to enterprises. In addition, because only the modification of the original global configuration file is carried out, and the regeneration and the restart of the cluster component can be carried out based on the modified new global configuration file, even if facing a cluster system with a more complex structure, the implementation mode can still realize the rapid and efficient IP modification and can effectively ensure the stable operation of the modified cluster system.
In an embodiment of the application, before the modifying the original global configuration file by using the preset IP modification list to obtain the new global configuration file, the method may further include: judging whether cluster node modification information exists in a preset IP modification list or not; if so, determining the cluster node to be modified according to the cluster node modification information, and modifying the current IP of the cluster node to be modified into the designated IP.
The method for modifying the IP of the cluster system provided by the embodiment of the application can further realize the IP modification of the cluster nodes, and the modification of the IP information of the cluster nodes can also be realized based on the preset IP modification list. Specifically, in the process of modifying the IP information by the cluster system, in addition to modifying the IP of each cluster component in the cluster system, the IP information of the cluster node may also be modified according to actual requirements, where the cluster node may include a working node (node), a management node (master), and the like. Based on the above, the node information of the cluster node to be modified, the original IP information, the modified IP information, and the like may also be recorded in the preset IP modification list. Therefore, after the preset IP modification list is obtained, before the original global configuration file is modified based on the preset IP modification list, whether modification information aiming at the cluster nodes exists in the preset IP modification list or not can be judged, if yes, the cluster nodes to be modified in the cluster system can be determined according to the cluster node modification information, and then the current IP (namely the original IP) is modified into the specified IP (namely the modified IP). Of course, if the cluster node modification information does not exist in the preset IP modification list, the step of modifying the original global configuration file by using the preset IP modification list to obtain a new global configuration file may be directly performed.
Specifically, a master _ booth _ node _ is _ change (whether to modify a node that is both a master and a node), a master _ only _ is _ change (whether to modify a pure master node), a node _ only _ is _ change (whether to modify a pure node), a keepalive _ VIP _ is _ change (whether to modify a virtual IP, which is a virtual IP of a K8S cluster, and which can access a K8S service by accessing the IP), and the like may be set to determine whether to modify the node; setting master _ only _ change (modifying a pure master node list), master _ both _ node _ change (modifying a node list which is a master and a node), node _ only _ change (modifying a pure node list), and keepalive _ vip _ change (modifying a virtual IP) to distinguish the types of nodes to be modified so that different types of nodes can carry out different operations; the node name + before/after is set to determine the specific modified content. The design structure is clear and all possible situations are considered.
In an embodiment of the application, before modifying the current IP of the cluster node to be modified to the designated IP, the method may further include: judging whether the specified IP meets a preset format specification or not; if not, outputting an error prompt; and if so, executing the step of modifying the current IP of the cluster node to be modified into the specified IP.
In order to further improve the IP modification efficiency, a uniform format specification can be set for the IP information so as to modify the IP of the cluster component into the IP with a preset format specification. Specifically, before modifying the current IP of the cluster node to be modified into the designated IP, it may be determined whether the designated IP in the preset IP modification list meets the preset format specification, if not, an error prompt may be directly output, the IP modification is not continued, and the exit is interrupted, if so, the step of modifying the current IP of the cluster node to be modified into the designated IP may be performed.
The specific type of the preset format specification does not affect the implementation of the present technical solution, for example, in the present application, it may be set as yaml format, which is not limited in the present application. Taking the yaml format as an example, when judging whether the designated IP is the yaml format, judging whether the format of the designated IP is 4 numbers and points of 0-255 by matching using a grep text search tool, and if so, determining that the designated IP meets the yaml format.
In an embodiment of the application, after the modifying the current IP of the cluster node to be modified to the designated IP, the method may further include: restarting the network service of the cluster system, and judging whether the network service is in a normal running state or not by executing a ping command; if not, outputting an error prompt; and if so, executing the step of modifying the original global configuration file by utilizing a preset IP modification list.
In order to effectively ensure that the cluster node can normally operate after IP modification, network service restart can be performed once after IP modification, and the network service of the cluster system can be ensured to enter a normal operation state. Specifically, after restarting the network service of the cluster system, whether the restarted network service is in a normal running state can be judged by executing a ping command, and the running state of the network server can be verified according to a ping command return value; further, when it is determined that the restarted network service is in a normal operation state, the modification of the original global configuration file may be continued, otherwise, if the restarted network service is in an abnormal operation state, an error prompt may be output, the IP modification is not continued, and the quitting is interrupted.
In an embodiment of the present application, the regenerating each cluster component according to the new global configuration file may include: and regenerating the ETCD certificate, the component certificate, the conf configuration file and the guide token according to the new global configuration file.
The embodiment of the application provides specific types of cluster components, namely the ETCD certificate, the component certificate, the conf configuration file, the guide token and the like. Of course, the specific type and number of cluster components are not limited to this, and the IP information of different cluster components may be modified according to the difference of the cluster system structure and the difference of the type, as described above, the specific cluster component type is determined by the cluster system structure itself, which is not limited in this application.
Taking the K8S cluster system as an example, the implementation procedure of performing IP modification on the cluster component thereof may include:
(1) deleting the old certificate file and the conf configuration file, defaulting to/etc/kubernets/pki and/etc/kubernets/. conf;
(2) regenerating the ETCD certificate: the ETCD certificate can be regenerated by using openssl or other methods, and the ETCD service is restarted;
(3) regenerating the conf profile of K8S: the modified IP information may be transmitted using a kubedm init phase kubeconfig command;
(4) regenerating the K8S component-related certificate: the modified IP information can be transmitted by using a kubbeam init phase headers command;
(5) regenerating bootstrap-token to enable the cluster to be capable of normally expanding and contracting;
(6) synchronizing the new certificate information to the K8S configuration center: a kubbeam init phase upload-centers synchronization certificate may be used;
(7) restarting the K8S component service to validate its new configuration;
(8) editing and modifying the IP information in the configmap (service configuration), daemonset (daemon service) and deployment (stateless service), so that the job on the K8S is executed again.
In an embodiment of the present application, traversing the cluster component in the cluster system to generate the original global configuration file may include: and traversing the cluster components in the cluster system by using a kubedm config view tool to generate an original global configuration file.
The embodiment of the application provides a method for generating an original global configuration file, which is realized based on a kubbeeadnfig view tool, wherein the kubbeeadnfig view tool is an operation and maintenance tool of kubbernees, and can be used for generating the global configuration file of a K8S cluster system so as to realize IP modification of the K8S cluster system, and the tool supports the above yaml format.
In an embodiment of the application, the modifying the original global configuration file by using the preset IP modification list to obtain a new global configuration file may include: and executing a preset IP modification list by using an ansable tool, and modifying the original global configuration file into a new global configuration file.
The embodiment of the application provides a method for modifying an original global configuration file into a new global configuration file, namely, automatic modification of IP information can be realized based on an ansable tool, and specifically, IP modification can be performed by using a lineinfile module or sed command of the ansable tool. The ansible tool is an automatic operation and maintenance tool, is used for publishing, managing and arranging a computer system, and can realize batch processing of remote control nodes based on resource lists and script tasks. Moreover, the ansible tool can also perfectly support the above yaml format, and can also realize the restart of the network service of the cluster system.
