Cloud computing platform provides the user what service usually presented with the formation of virtual machine, and the reliability of virtual machine is highly important for cloud computing platform.The core system of virtual machine or service are due to unknown cause or unexpected machine of delaying, it will bring the loss that cannot estimate to the user of enterprise and cloud computing platform.
For the problems referred to above, present embodiments providing a kind of new cloud computing platform management method, the method enables to the operation of physical host and virtual machine in cloud computing platform and all supports High Availabitity.In the present embodiment, High Availabitity refers to by shortening the downtime because the system crash (unplanned) of routine maintaining operations (plan) or burst causes as far as possible, to improve the availability of system and application.High Availabitity is that enterprise prevents kernal computer system because of the most effective means of disorderly closedown.
Specifically, as it is shown in figure 1, first the method that the present embodiment provides obtains the High Availabitity state of physical host in cloud computing platform in step S101, and judge whether physical host is in High Availabitity state in step s 102.If physical host is in High Availabitity state in cloud computing platform, then continue executing with subsequent step, otherwise no longer carry out operation bidirectional.
In the present embodiment, the method obtains by obtaining the High Availabitity on off state of physical host and judges the High Availabitity state of physical host.When the High Availabitity of physical host switchs and is in opening, this physical host is in High Availabitity state.
If the physical host in cloud computing platform is in High Availabitity state, the method will obtain the running status of physical host in cloud computing platform in step s 103, and the running status according to acquired physical host determines faulty physical main frame.
In the present embodiment, the method obtains the running status of physical host by the physical host operation information obtained.Wherein, physical host operation information preferably includes: CPU uses status information, internal memory to use status information, exchange partition information, hard disk to use status information, network state information, the running state information of virtual machine and timestamp information etc..Certainly, in other embodiments of the invention, acquired physical host operation information can also comprise other appropriate messages, the invention is not restricted to this.
Specifically, if the method cannot get the related status information of physical host in cloud computing platform in step s 103, then judgement now this physical host is in malfunction by the method.If additionally, the method determines that some the preset service process in physical host stops or operation exception in step s 103, then judgement now this physical host service is also in malfunction by the method.
Such as, when the network service of physical host is broken down, cloud computing management platform will be unable to get the running status of this physical host, and therefore cloud computing management platform is also it may determine that go out now this physical host to be in malfunction.
As in figure 2 it is shown, in the present embodiment, when judging whether physical host is in malfunction according to preset service running state of a process, obtain preset service running state of a process first in step s 201.Wherein, in different embodiments of the invention, preset service process can be set according to the needs of user, and it can be the service processes of such as Libvirtd, the invention is not restricted to this.
In step S202, judge this preset service process whether fault according to preset service running state of a process accessed in step S201.If this preset service process failure, then in step S203, restart this preset service process.Complete, after the restarting of this preset service process, judging that in step S204 whether the preset service process after restarting is normal.If this preset service process resumption is normal, then do not carry out other operation；If this preset service process still in malfunction, then determines whether restarting number of times and whether reaching first and preset and restart number of times of this service processes in step S205.
If this service processes restart number of times be not reaching to first preset restart number of times, then after waiting the first preset duration in step S207 return step S203 again to restart this service processes.If this service processes restart number of times reach first preset restart number of times, then will judge that in step S206 the physical host now performing this service processes is in malfunction.
In the present embodiment, first presets and restarts number of times and be preferably configured to 3 times, and the first preset duration is preferably configured to 30 seconds.It is pointed out that in other embodiments of the invention, first presets and restarts number of times and the first preset duration can also be configured to other reasonable values according to actual needs, the invention is not restricted to this.Such as in one embodiment of the invention, first preset restart other reasonable values that number of times is also configured as in [2,10], the first preset duration is also configured as other reasonable values in [10, the 50] second.
Again as it is shown in figure 1, after faulty physical main frame in determining cloud computing platform, the virtual server in faulty physical main frame is rebuild by the method.Specifically, the method obtains virtual machine list and the virtual machine configuration of faulty physical main frame in step S104, and rebuilds the virtual machine in virtual machine list according to virtual machine configuration.In step S104, the method also completes the backup to the preservation of magnetic disk of virtual machine file in faulty physical main frame and disc content.
In step S105, obtain available physical Host List, and according to rebuilding the automatic deployment strategy of virtual machine, from available physical main frame, determine that effective physical host carries out rebuilding the deployment of virtual machine.In the present embodiment, available physical main frame needs to meet following condition: one, and available physical main frame needs to be in High Availabitity state, and namely the High Availabitity switch of available physical host needs to be in opening；Its two, the resource such as the free memory of available physical main frame, available CPU needs to meet the resource allocation request waiting to dispose virtual machine.
In the present embodiment, the automatic deployment strategy followed when disposing virtual machine preferably includes four kinds of deployment strategys, i.e. the sparse type deployment strategy of virtual machine, virtual machine intensity deployment strategy, CPU responsive type deployment strategy and internal memory responsive type deployment strategy.
Wherein, the sparse type deployment strategy of virtual machine selects the physical host having disposed virtual machine minimum number to carry out the deployment of virtual machine when disposing virtual machine, virtual machine intensity deployment strategy selects when disposing virtual machine to have disposed the maximum physical host of virtual machine quantity to carry out the deployment of virtual machine, CPU responsive type deployment strategy selects to come the deployment of virtual machine with the physical host that CPU is maximum when disposing virtual machine, and internal memory responsive type deployment strategy selects the physical host that free memory is maximum to carry out the deployment of virtual machine when disposing virtual machine.
Certainly, in other embodiments of the invention, the automatic deployment strategy of virtual machine can also comprise other rational strategy, the invention is not restricted to this.
As it is shown in figure 1, after the deployment completing virtual machine, the magnetic disk of virtual machine file of preservation is utilized to cover the disk file disposing the virtual machine obtained in step s 106, thus virtual machine after deployment recovers the disc content of corresponding virtual machine in faulty physical main frame.
In the present embodiment, as it is shown on figure 3, in order to ensure the uniqueness of same virtual machine in cloud computing platform, the method continues to monitor the running status of faulty physical main frame in step S301, and whether failure judgement physical host recovers normal in step s 302.If faulty physical main frame recovers normal, then then delete in faulty physical main frame in step S303 and be deployed to the virtual machine on other physical hosts, to ensure the uniqueness of same virtual machine in environment.And if faulty physical main frame does not recover normal, then then return in step S301 and continue to be monitored.
Such as, when the network service of faulty physical main frame recovers normal, cloud computing platform can reacquire the running status of former faulty physical main frame, and then judges the fault recovery of this faulty physical main frame, and this faulty physical main frame recovers to normal condition.Now cloud computing platform has been deployed to the virtual machine on other physical hosts by deleting on former faulty physical main frame, thus ensureing the uniqueness of same virtual machine in environment.
The method that the present embodiment provides by recovering to be deployed in normal rear this faulty physical main frame of deletion the virtual machine of other physical hosts at faulty physical main frame, thus ensure that the uniqueness of same virtual machine in cloud computing platform, and then improve the utilization rate calculating resource in cloud computing platform.
In the present embodiment, when physical host itself does not break down, and it is only a certain in physical host or when certain several virtual machine breaks down, the method that the present embodiment provides improves the high availability of virtual machine by automatically restarting the mode of fault virtual machine.
Specifically, as shown in Figure 4, the method obtains the High Availabitity state presetting virtual machine in step S401, and judges to preset whether virtual machine is in High Availabitity state in step S402.In the present embodiment, in the present embodiment, the method is by obtaining the High Availabitity state that the High Availabitity on off state of this virtual machine obtains and judges this virtual machine.When the High Availabitity of virtual machine switchs and is in opening, this virtual machine is then in High Availabitity state.
If virtual machine machine is in High Availabitity state, the method will obtain the running status of virtual machine in step S403, and judges whether this virtual machine breaks down according to the running status of acquired virtual machine in step s 404.If this virtual machine breaks down, then in step S405, restart this virtual machine.Completing after the restarting of this fault virtual machine, in step S406, again judge whether this fault virtual machine recovers normal.If this virtual machine does not recover normal yet, then determine whether restarting number of times and whether reaching second and preset and restart number of times (namely preset virtual machine restart number of times) of this fault virtual machine in step S 407.If this fault virtual machine restart number of times reach second preset restart number of times, then do not continue to restart this fault virtual machine；Return in step S405 again to restart this fault virtual machine after otherwise waiting the second preset duration in step S408.
In the present embodiment, second presets and restarts number of times and be preferably configured to 3 times, and the second preset duration is preferably configured to 30 seconds.It is pointed out that in other embodiments of the invention, second presets and restarts number of times and the second preset duration can also be configured to other reasonable values according to actual needs, the invention is not restricted to this.Such as in one embodiment of the invention, second preset restart other reasonable values that number of times is also configured as in [2,10], the second preset duration is also configured as other reasonable values in [10, the 50] second.
It is to be noted, in other embodiments of the invention, physical host and the High Availabitity switch of virtual machine in cloud computing platform are also configured as omnidistance opening, also just can no longer judge whether physical host and virtual machine are in High Availabitity state so in the above-mentioned methods, thus simplifying handling process, improve operational efficiency.
Can be seen that in from the above, the cloud computing platform management method that the present embodiment provides is capable of the operational factor to physical host, emphasis service operation state and virtual machine running status and is monitored, service processes fault, physical host fault and virtual-machine fail can be monitored as quickly as possible, and fault processes to recover physical host or virtual machine good for use as quickly as possible, thus improve the high availability of cloud computing platform, improve Consumer's Experience.
