Detailed Description
The technical solution of the present invention will be described in detail below with reference to the embodiments and the accompanying drawings.
The invention provides a management method for maintaining a working node of a cloud computing system, which comprises a maintenance mode entering part, a maintenance mode exiting part and a task scheduling part;
the enter maintenance mode part includes:
step S1, the cloud computing system management center monitors whether a maintenance request for any working node is received, and if the maintenance request for any working node is received, the step S2 is executed;
step S2, the cloud computing system management center informs the task scheduler that the working node enters a maintenance mode;
step S3, the cloud computing system management center informs the working node to enter the maintenance mode, and after receiving the notice of entering the maintenance mode, the working node migrates the application instance on the current node to the working node which does not enter the maintenance mode;
step S4, the working node stops the application instance on the current node;
the exit from maintenance mode portion includes:
the method comprises the steps that a cloud computing system management center monitors whether a maintenance quitting request for any working node is received or not, and if the maintenance quitting request for any working node is received, a task scheduler is informed that the working node does not enter a maintenance mode;
the task scheduling part comprises:
and when the task scheduler deploys the application instances to each working node, not deploying the application instances to the working nodes entering the maintenance mode according to the mode of each working node.
By the management method, when a user needs to maintain a certain working node, a request for maintaining the corresponding working node is directly input into the cloud computing system, then the cloud computing system stops distributing a new task to the working node needing to be maintained, an application instance on the working node needing to be maintained is migrated to other working nodes which normally run for processing, after the application instance on the working node needing to be maintained stops running, the user can maintain the working node needing to be maintained, after maintenance is completed, the user directly inputs a request for quitting the corresponding working node to be maintained into the cloud computing system, then the task distributor can distribute the new task to the corresponding working node which quits maintenance, and the corresponding working node which quits maintenance runs normally.
The method is further optimized, and specifically, the following aspects can be provided:
on one hand, the step S3 of migrating the application instance on the current node to the working node that does not enter the maintenance mode may specifically adopt: the working node requests the task scheduler to redeploy the application instance on the current node; the method comprises the steps that a cloud computing system management center monitors whether application instances on a current working node are completely redeployed to the working node which does not enter a maintenance mode and can provide corresponding services for the outside, if yes, first notification information is sent to the working node, and if not, the first notification information is not sent to the working node; the worker node, upon receiving the first notification information, executes step S4. Through the optimization, the application instance to be stopped on the working node needing maintenance is stopped after the application instance to be stopped on the working node needing maintenance is ready on other working nodes again and can provide service to the outside, the phenomenon of service interruption can not occur on the application layer, and non-stop maintenance is realized.
On the other hand, the cloud computing system may adopt a cloud computing system based on container technology. By adopting the cloud environment based on the container technology, the workload of operation and maintenance personnel can be greatly reduced, and the safety and the portability of the system are better.
On the other hand, the cloud computing system management center receives a maintenance request and a maintenance quitting request for any working node by providing a command input line and/or a webpage button. The user can operate the device more conveniently and quickly.
Examples
The following specifically exemplifies the technical solution of the present invention.
In this example, the overall maintenance flow chart is shown in fig. 1, where the cloud computing system is a container cloud computing system, and it is assumed that the container cloud computing system in this example has a work node one, a work node two, and a work node three.
In the practical application process, when a user needs to maintain a first working node, the user selects to maintain the first working node through a webpage button provided by a container cloud computing system management center, and at the moment, the container cloud computing system management center receives a maintenance request for the first working node; then the management center of the container cloud computing system informs the task scheduler that the working node enters a maintenance mode, and the task scheduler does not distribute a new application instance to the working node; and then the container cloud computing system management center informs the first working node of entering a maintenance mode, the first working node requests the task scheduler to relocate the application instance on the current node after receiving the notification of entering the maintenance mode, the task scheduler responds to the request of the first working node to perform corresponding processing, in addition, the container cloud computing system management center starts to monitor whether all the application instances on the first working node are relocated to the working nodes which do not enter the maintenance mode and can provide corresponding services for the outside, if yes, first notification information is sent to the first working node, and if not, the first notification information is not sent to the first working node.
In this embodiment, the working nodes to which the application instance on the working node one can be redeployed are a working node two and a working node three; assuming that the application instance on the first working node is already redeployed and can provide corresponding service to the outside, the first working node receives the first notification message, and the first working node stops the application instance on the current node after receiving the first notification message. Therefore, the application instance on the first working node is safely migrated to the second working node and/or the third working node, and the operation and maintenance personnel can perform maintenance operation on the server in the first working node.
It should be noted that, after the maintenance is completed, the user selects to quit the maintenance on the first working node through a webpage button provided by the container cloud computing system management center, and at this time, the container cloud computing system management center receives a request for quitting the maintenance on the first working node; the container cloud computing system management center then notifies the task scheduler that the worker node will not enter the maintenance mode, and thereafter the task scheduler will normally allocate a new application instance to the worker node, and the worker node will normally process the application instance thereon.
