For the purpose, technical scheme and advantage of the disclosure are more clearly understood, below in conjunction with specific embodiment, and reference
Accompanying drawing, the disclosure is further described.
The one side of the embodiment of the present disclosure, there is provided a kind of conversion method of server, Fig. 1 are the clothes of the embodiment of the present disclosure
The step schematic diagram of the conversion method of business device, as shown in figure 1, the conversion method comprises the following steps：
S1, the situation for obtaining from server database calculation server, include the data and number of calculation server
Deng, then judge the state of calculation server.In general, bare metal server can not be virtualized, and cloud management platform can only
Manage bare metal server in itself, and calculation server can virtualize, and obtain at least one virtual machine, these virtual machines can
By cloud management platform management, therefore, server database meeting prioritizing selection calculation server, calculation server should be judged herein
State.
S2, the state according to the calculation server, realize and mutually turn between calculation server and bare metal server
Change, wherein, the calculation server includes mirror image, computation module and virtual machine, and the bare metal server includes mirror image and naked
Metal assembly.The mirror image is static uninstalled operating system, and the virtual machine is produced by computation module and mirror image.Typically
Ground, bare metal component can configure the bare metal server, such as network configuration according to the first management role that cloud platform is sent.
The second management role that computation module can be sent according to cloud platform, the virtual machine is managed, such as create and delete virtual machine.
In general, the state of calculation server can be judged by underload algorithm and overload algorithm, such as passed through
The CPU (central processing unit) of calculation server and the utilization rate of internal memory are judged, in this way, just can quickly judge the negative of calculation server
Load state.
Fig. 2 is the schematic flow sheet of the transfer process of the embodiment of the present disclosure, as shown in Fig. 2 the transfer process is specially：
By calculation server overload algorithm, judge whether calculation server is in overload state.If calculate service
The state of device is overload, then selects the bare metal server of free time, delete bare metal component therein, and described idle
Computation module is installed on bare metal server, the idle bare metal server is converted into calculation server.By by the free time
Bare metal server be converted into calculation server, alleviate the state of calculation server overload, realize bare metal service
Effective distribution of resources between two clusters of device and calculation server.
When calculation server is not at overload state, then using calculation server underload algorithm, judge to calculate clothes
Whether business device is in underload state.If the state of calculation server is underload, the calculation server of free time is selected, is deleted
Computation module therein, by the virtual machine (vm) migration on the idle calculation server to remaining any calculation server, and
Bare metal component is installed on the idle calculation server, the idle calculation server is converted into bare metal server.
It is understood that one side user can be by accessing the calculation server after virtual machine (vm) migration, to obtain in virtual machine
Data, the another aspect idle calculation server can be converted into bare metal server and provide the user service.
In order to prevent the calculation server after conversion or bare metal server to be unable to normal use, the conversion method can be with
Including the calculation server or bare metal server ip address after step S3, modification conversion, and to the calculating service after conversion
Device or bare metal server are restarted.
The another aspect of the embodiment of the present disclosure, additionally provides a kind of conversion equipment of server, and Fig. 3 is the embodiment of the present disclosure
Server conversion equipment structural representation, as shown in figure 3, the conversion equipment includes condition adjudgement unit 1 and conversion is single
Member 2.
Condition adjudgement unit 1, for judging the state of calculation server.Wherein, the condition adjudgement unit 1 can be by owing
Loading algorithm and overload algorithm judge the state of calculation server, more specifically, underload algorithm and overload algorithm can be with
Realized by judging CPU and the memory usage of calculation server.
Converting unit 2, for the state according to the calculation server, realize calculation server and bare metal server it
Between mutual conversion, wherein, the calculation server includes mirror image, computation module and virtual machine, the bare metal server bag
Include mirror image and bare metal component.The virtual machine is produced by computation module and mirror image, and the mirror image is static uninstalled behaviour
Make system, bare metal component is used to configure the bare metal server, computation module according to the first management role that cloud platform is sent
For the second management role sent according to cloud platform, the virtual machine is managed.
Further, the concrete implementation mode of converting unit 2 is：
By calculation server overload algorithm, judge whether calculation server is in overload state.If calculate service
The state of device is overload, then selects the bare metal server of free time, delete bare metal component therein, and described idle
Computation module is installed on bare metal server, the idle bare metal server is converted into calculation server.By free time it is naked
Metal server is converted into calculation server, takes full advantage of the bare metal server of free time, it is excessively negative to alleviate calculation server
The state of load, realize the reasonable disposition of resource.
When calculation server is not at overload state, then using calculation server underload algorithm, judge to calculate clothes
Whether business device is in underload state.If the state of calculation server is underload, the calculation server of free time is selected, is deleted
Computation module therein, by the virtual machine (vm) migration on the idle calculation server to remaining any calculation server (with
Prevent the loss of data in calculation server, the calculation server that user need to only be provided with virtual machine by accessing can obtain pair
The data answered), and bare metal component is installed on the idle calculation server, the idle calculation server is converted into naked
Metal server.One side user can be by accessing the calculation server after virtual machine (vm) migration, to obtain the number in virtual machine
According on the other hand the idle calculation server can also be converted into bare metal server and provide the user service, can prevent
There is the situation of resource allocation inequality between idle, two kinds of servers in calculation server.
In addition, in order to prevent the calculation server after conversion or bare metal server to be unable to normal use, the conversion equipment
Modification unit can also be included, for changing calculation server or bare metal server ip address after changing, and to conversion
Calculation server or bare metal server afterwards is restarted.
The conversion equipment and method of the server of the disclosure, are owed by calculation server overload algorithm and calculation server
Loading algorithm, judge the load condition of calculation server, always according to the load condition, change calculation server and bare metal clothes
The separate state of business two clusters of device, realizes that the two clusters are turned according to the difference of the load condition of calculation server
Change so that the use of two kinds of servers reaches the state of balance, realizes the reasonable utilization of resource.Further, service is calculated
The conversion regime of device and bare metal server is simple, easily operated.
