Abstract
The present invention relates to cloud computing management technique field, particularly relate to subprocess maintaining method under a kind of cloud computing environment.After first the present invention manages node and realizes node processes startup, registration closedown process hook, it is used for processing subprocess；Then subprocess produces and records to subprocess Maps, removes Maps during destruction；When then managing node and realize node processes by closing, first call hook thread；Finally perform hook thread, close all record subprocess inside subprocess Maps.The method maintainability of the present invention is good, when host process is closed, can preferentially close all subprocess, it is adaptable to the order that the time that performs in cloud computing environment is longer.
Description
Technical field
The present invention relates to cloud computing management technique field, particularly relate to subprocess maintaining method under a kind of cloud computing environment.
Background technology
In cloud computing solution, management node is deposited realizing node (calculating node, memory node, network node etc.)
Control work in substantial amounts of order, especially realize the end operational order for underlying virtual.Generally for realizing program
Loose coupling, be to separate for the operational order of bottom and the program of management end, it is achieved hold and the order of bottom is only responsible for
Calling, underlying operating system is responsible for execution, and returns result.But times longer order is performed for some, such as copy
Mirror image, the transmission operation such as file, packing, it is impossible to by realizing end and interrupt it, cancels operation, such as closedown realizes end and enters
Cheng Shi, being currently executing in theory of task also should close, and returns and perform failure.Can only lead to for this kind of situation at present
Cross underlying operating system execution related command and carry out the maintenance work of correlator process, so suffer from the drawback that
1, be that maintainability is poor, need to enter each calculating node and check the subprocess needing to stop, it is possible to finding time
Wait subprocess to have performed；
2, dangerous, easily produce zombie process, close owing to maintenance needs when realizing end host process, held by realizing end
The order subprocess of row likely becomes zombie process, thus the system that affects normally uses；
In order to from truly realizing the Rational Maintenance of subprocess under cloud computing environment, need one when management node
Or realize the maintenance mechanism that when node processes is closed, subprocess is automatically switched off.
Summary of the invention
Present invention solves the technical problem that and be to provide subprocess maintaining method under a kind of cloud computing environment, solve tradition side
The deficiency that method exists, provides a kind of maintainability high for subprocess under cloud computing environment, the solution that safety is good.
It is to comprise the following steps that the present invention solves the technical scheme of the problems referred to above:
Described method comprises the steps:
Step 1: after managing node and realizing node processes startup, registration closedown process hook, it is used for processing subprocess；
Step 2: subprocess produces and records to subprocess Maps, removes Maps during destruction；
Step 3: when managing node and realize node processes by closing, first call hook thread；
Step 4: perform hook thread, close all record subprocess inside subprocess Maps.
Described management node is the management module in cloud computing solution respectively with realizing node and realizes module；
Described management module refers to be responsible for generation task, transmission task, reception task feedback in cloud computing solution
Service control management module, this module is only responsible for generation task, and irresponsibility is pragmatic existing；
The described module that realizes is to be responsible for consumption task, the business function module that task realizes in cloud computing solution.
Described process hook, is Runtime.addShutdownHook method in JAVA, is used for increasing in jvm one
The hook of individual closedown；When program normally exits, system calls System.exit method or virtual machine just can perform to add when being closed
The shutdownHook thread added；Wherein shutdownHook is one and has initialized but do not have the thread of startup, when JVM closes
The when of closing, all hooks added by method addShutdownHook that can be the most configured in execution system, when system is held
Having gone after these hooks, JVM just can close.
Described subprocess produces and records to subprocess Maps, removes Maps during destruction；
Described subprocess, is that under cloud computing environment, some by management node or realize the bottom operation life that node is initiated
Order, the subprocess of generation；
Described process Maps, is primarily adapted for use in the id of the information table recording all subprocess, such as subprocess, title,
Content etc..
The method maintainability of the present invention is good, when host process is closed, can preferentially close all subprocess, it is adaptable to cloud computing ring
The order that the time that performs in border is longer.The method security of the present invention is high, it is to avoid owing to host process is closed, and cause subprocess
Become the risk of zombie process, improve the stability of system, reduce the long-time terminate-and-stay-resident of subprocess, cause JVM virtual machine
Crash or the high risk of Installed System Memory utilization rate.
Accompanying drawing explanation
The present invention is further described below in conjunction with the accompanying drawings:
Fig. 1 is the flow chart of the present invention；
Fig. 2 is the technical schematic diagram of the present invention；
Detailed description of the invention
As shown in Figure 1, 2, essential core of the present invention is to be linked up with by process to realize, and specific implementation process is as follows:
1, after managing node and realizing node processes startup, registration closedown process hook, it is used for processing subprocess；
AddShutdownHook (Thread hook) method of Runtime object registers new virtual machine to close extension
Hook.Hook thread realizes environment cleaning work.
2, subprocess produces and records to subprocess Maps, removes Maps during destruction；
When 3, managing node and realize node processes by closing, first call hook thread；
4, perform hook thread, close all record subprocess inside subprocess Maps.
When such as establishment virtual machine does not carry out mirror image cache, automatically can be mirrored to cache catalogue by copy.At copy
During, realizing end process id by kill, ctrl+C is when cancelling, relevant dd process disappears.
