For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
The present embodiment is mainly the scheduling of reaching the standard grade with off-line to operating in a plurality of virtual servers on physical server, as shown in Figure 1, at physical server inner setting the dispatching patcher 100 of one virtual server line duration.
As shown in Figure 1, the dispatching patcher 100 of this virtual server line duration mainly comprises administration module 10, scheduler module 20, synchronization module 30, forwards control module 40 and timing module 50.
Wherein, administration module 10, for create at least two virtual servers on physical server, is formulated virtual server list, and according to the dispatch command receiving, corresponding virtual server is reached the standard grade and off-line operation.
It should be noted that, in virtual machine technique field, install operating system and WEB service in a virtual machine after, this virtual machine can be used as a virtual server.In the virtual machine creating, install respectively operating system, and required WEB application on disposing respectively in each operating system, make each virtual machine become the virtual server of this WEB application, each virtual machine can independently externally provide WEB service.
Installing operating system while disposing WEB application, can adopt safe diversification strategy.In the present embodiment, the virtual machine using is all the virtual server of WEB application, preferably, the operating system of different platform is installed for different virtual machine server, but all dispose identical WEB application, can make like this assailant's work more complicated, and then can strengthen the fail safe of virtual server.
Shown in Fig. 2, be the network connection architecture figure of 4 virtual servers.In this example, administration module 10 has created 4 virtual servers.Shown in Fig. 2 is the network structure of these four virtual servers.In this example, and each virtual server at least comprises two Microsoft Loopback Adapters (preferably two Microsoft Loopback Adapters).
As shown in Figure 2, virtual server 1, virtual server 2, virtual server 3 and virtual server 4 include two Microsoft Loopback Adapters, wherein a Microsoft Loopback Adapter is for linking the inner high speed local area network (LAN) between virtual machine, another piece Microsoft Loopback Adapter is for being connected with external network, the inner high speed local area network (LAN) between virtual machine completely and external network completely cut off.Can strengthen the fail safe of virtual server like this.
Administration module 10 describes in detail after receiving from scheduler module 20() dispatch command after, the off-line that the state of the Microsoft Loopback Adapter by change respective virtual server is realized virtual server with reach the standard grade operation.That is, the state by Microsoft Loopback Adapter is set to opening, realizes reaching the standard grade of virtual server, and the state by Microsoft Loopback Adapter is set to closed condition, realizes the off-line of virtual server.
In addition, administration module 10, except carrying out aforesaid operations, also manages the life cycle of virtual server.Comprising: start virtual server, close virtual server, delete virtual server, add virtual server, upgrade virtual server information, check virtual server details, on virtual machine display console, show managed virtual server list.
For scheduler module 20, it is for arranging virtual server scheduling strategy and line duration threshold value, when the virtual server dispatch request receiving from timing module 50, the virtual server that line duration is reached to line duration threshold value is defined as the virtual server of wanted off-line, from virtual server list, select the virtual server that meets scheduling strategy to be defined as the virtual server that will reach the standard grade simultaneously, and send corresponding dispatch command to administration module 10.
Below in conjunction with timing module 50, illustrate how to dispatch.Timing module 50 carries out timing to the line duration of each virtual server, and when the line duration of virtual server reaches the line duration threshold value of formulating in scheduler module 20, to scheduler module 20, send the dispatch request of reaching the standard grade with off-line for virtual server.According to received dispatch request, the virtual server that scheduler module 20 reaches line duration line duration threshold value is on the one hand defined as the virtual server of wanted off-line, in virtual server list from administration module 10, choose on the other hand meet virtual server scheduling strategy virtual server as the virtual server that will reach the standard grade, and to administration module 10, send dispatch commands and realize the off-line of virtual server and the state conversion of reaching the standard grade with the state of the Microsoft Loopback Adapter of notice administration module 10 change virtual servers.
Preferably, above-mentioned scheduling strategy is included in and in all off-line virtual servers, selects the longest virtual server of off-line time or the minimum virtual server of load as the virtual server that will reach the standard grade and allow online virtual server quantity to be simultaneously no more than half of virtual server quantity summation on physical server.
In detail, preferentially select the longest virtual server of off-line time to refer to and from the virtual server of all off-lines, select one in the longest virtual server of the time of off-line state, as the virtual server that will reach the standard grade; The minimum virtual server of preferential selection load refers to selects a virtual server that load is minimum from the virtual server of all off-lines, as the virtual server that will reach the standard grade.
In addition, scheduler module 20 is gone back on-line time and the off-line time of each virtual server of real-time servicing, and each online time of assurance virtual server is no more than set point, and guarantees that each has online virtual server constantly simultaneously.
Further, for the normal operation that guarantees WEB service is not because the switching of virtual server is interrupted, synchronization module 30 need to be synchronized to the data in the virtual server of wanted off-line and session status for replacing its virtual server that will reach the standard grade, and so-called session status refers to the state of the session of setting up between client and the virtual server of the off-line of wanting.
In addition, owing to moving a plurality of virtual servers on physical server, in order to simplify the complexity of system, forwarding control module 40 is that each virtual server operating on physical server arranges unified IP address and port, and the external request of this IP address of access and port is forwarded to the virtual server of newly reaching the standard grade.; if administration module 10 has carried out off-line and has reached the standard grade after operation; if exist the external request of this IP address of an access and port to send to the virtual server A of firm off-line; now just this external request need to be sent on the virtual server B that replaces this virtual server A; when can guarantee virtual machine security like this, can also continual service provide.
It should be noted that and according to self-defining line duration threshold value, dispatch that virtual server is reached the standard grade and off-line, can reduce the time that virtual server exposes in the Internet, thereby make assault virtual machine more difficult, greatly improved the degree of safety of server.Such as, if be 1 minute by the line duration threshold value setting of virtual server, virtual server is reached the standard grade 1 minute with regard to off-line, makes hacker only have the time of 1 minute to attack; If virtual server line duration is arranged shortlyer, the invasion time that hacker can utilize is just shorter.
From another viewpoint, the present invention also proposes a kind of dispatching method of virtual server line duration.Below in conjunction with the dispatching patcher 100 of above-mentioned virtual server line duration, each step of the scheduling of virtual server line duration is described.
Fig. 3 is the flow chart of the dispatching method of virtual server line duration according to another embodiment of the present invention.Please also refer to Fig. 1 and Fig. 3, first as shown in step S310, administration module 10 creates at least two virtual servers on physical server, and formulates virtual server list, further according to the dispatch command receiving, corresponding virtual server is reached the standard grade and off-line operation.
In addition, the life cycle of 10 pairs of virtual servers of administration module manages and comprises: start virtual server, close virtual server, delete virtual server, add virtual server, upgrade virtual server information, check virtual server details, on virtual machine display console, show managed virtual server list.
Then, in step S320, timing module 50 carries out timing to the line duration of each virtual server, and when the line duration of virtual server reaches line duration threshold value, to scheduler module 20, sends virtual server dispatch request.
Then, in step S330, scheduler module 20 arranges virtual server scheduling strategy and line duration threshold value, it is when the virtual server dispatch request receiving from timing module 50, the virtual server that line duration is reached to line duration threshold value is defined as the virtual server of wanted off-line, from virtual server list, select the virtual server that meets scheduling strategy to be defined as the virtual server that will reach the standard grade simultaneously, and send corresponding dispatch command to administration module 10.
As mentioned above, preferably, this virtual server scheduling strategy is included in and in all off-line virtual servers, selects the longest virtual server of off-line time or the minimum virtual server of load as the virtual server that will reach the standard grade and allow online virtual server quantity to be simultaneously no more than half of virtual server quantity summation on physical server.
Afterwards, as shown in step S340, synchronization module 30 is synchronized to the data in the virtual server of wanted off-line and session status for replacing its virtual server that will reach the standard grade, thereby the normal operation that guarantees WEB service is not because the switching of virtual server is interrupted.
Finally, in step S350, forward control module 40 for each virtual server operating on described physical server arranges unified IP address and port, the external request of access described IP address and port is forwarded to the virtual server of newly reaching the standard grade.
