Description

  The present invention relates to an information processing system for constructing a virtual machine, a control method for the information processing system, and a program.

  The use of an information processing system to which cloud technology for constructing a virtual machine that performs processing according to a request from a user and returns a processing result by using resources on a network is expanding. Resources in such an information processing system include a lower layer resource such as CPU (Central Processing Unit), memory, storage, IP address, VLANID (Virtual Local Area Network ID), OS (Operating System), middleware, application, etc. Up to upper layer resources.

  In the information processing system described above, an upper layer resource OS, middleware, application, or the like is operated on the virtual machine, and the IP address of the virtual machine or another virtual machine is used to perform processing according to the request. It may be necessary to set information of lower layer resources such as upper layer resources.

  As a method for setting the upper layer resource, there is a method in which the system administrator accesses the upper layer resource and manually sets it. However, this method has a problem that it takes time to set up and cannot provide a quick service. Therefore, there is a demand for a method for automatically setting upper layer resources.

  Patent Document 1 (Japanese Patent Application Laid-Open No. 2005-44201) discloses that in a system including a network device and a home gateway server, the network device connects to the network after the home gateway server grasps information about the network device in advance. A method for automatically setting the resource is disclosed.

  Further, in Non-Patent Document 1, a server having information on resource settings and a client for setting resources are connected via a network, and the client acquires information on resource settings from the server and performs settings. A method is disclosed.

In FIG. 1, only one virtual machine 20 is illustrated, but normally a plurality of virtual machines 20 are constructed.

  The virtual machine 20 operates upper layer resources such as OS, middleware, and application using the lower layer resources allocated by the lower layer management apparatus 10 and performs processing according to the request.

  Next, the configuration of the lower layer management apparatus 10 will be described.

  The lower layer management apparatus 10 includes a virtual machine execution unit 11, a lower layer information management unit 12, and a lower layer information transmission unit 13.

  The virtual machine execution unit 11 is a so-called virtual machine monitor, hypervisor, or the like, and constructs the virtual machine 20 by allocating lower layer resources according to a request from the user.

  The lower layer information management unit 12 includes lower layer information indicating lower layer resources allocated to each virtual machine 20 by the virtual machine execution unit 11, virtual machine identification information for identifying the virtual machine, and the virtual machine from the user. Upper layer resource identification information for identifying upper layer resources necessary for performing processing according to the request is generated and output to the lower layer information transmission unit 13.

  The lower layer information transmission unit 13 transmits the lower layer information and the upper layer resource identification information corresponding to the virtual machine 20 to the virtual machine 20 indicated by the virtual machine identification information output from the lower layer information management unit 12. To do.

  Next, the configuration of the virtual machine 20 will be described.

  The virtual machine 20 includes a lower layer information receiving unit 21, a storage unit 22, a setting file generation unit 23, and a script execution unit 24. For convenience of explanation, the virtual machine 20 will be described as having the above-described units. However, the operation of each unit may be performed using “init.d” as a startup program for the OS of the virtual machine 20 using a CPU, memory, storage, and the like. It is realized by performing processing of a program stored in a directory such as “”.

  The lower layer information reception unit 21 receives the lower layer information and the upper layer resource identification information transmitted from the lower layer management apparatus 10 and outputs them to the setting file generation unit 23.

  The storage unit 22 has predetermined portions that change according to the allocation of lower layer resources to each virtual machine 20 among the setting contents necessary to operate each upper layer resource and perform processing according to the request. The upper layer resource setting template described in the character string is stored. Hereinafter, the predetermined character string is referred to as a replacement character string. The upper layer resource setting template is created in advance by the upper layer operator and stored in the storage unit 22.

  In addition, the storage unit 22 stores the upper layer resource setting template for each upper layer resource, operates the upper layer resource, and performs processing corresponding to the request for the upper layer resource of the virtual machine 20. The storage location of the setting file indicating the setting contents and the upper layer setting target information indicating the permission setting indicating whether or not the setting file can be accessed are stored.

  The setting file generation unit 23 generates a setting file using the upper layer setting target information and the upper layer resource setting template and the lower layer information and the upper layer resource identification information output from the lower layer information receiving unit 21.

  The script execution unit 24 acquires a startup script stored at a location that can be referred to by the startup program of the OS running on the virtual machine 20, and the configuration file generated by the configuration file generation unit 23 according to the startup script Is set for the virtual machine 20 (upper layer resource thereof), the upper layer resource is operated, and processing according to the request is performed. Note that the startup script is created in advance by an upper layer operator and stored in a predetermined position.

  Next, the operation of the information processing system 1 of this embodiment will be described.

  FIG. 2 is a sequence diagram showing an operation at the time of setting file generation in the information processing system 1 of the present embodiment.

  The lower layer information management unit 12 generates lower layer information indicating lower layer resources such as an IP address assigned to each virtual machine 20 (step S101). The lower layer information management unit 12 also includes virtual machine identification information for identifying a virtual machine, and upper layer resource identification information for identifying an upper layer resource necessary for the virtual machine to perform processing according to a request from the user. And generate The lower layer information management unit 12 outputs the generated lower layer information, virtual machine identification information, and upper layer resource identification information to the lower layer information transmission unit 13 (step S102).

  The lower layer information transmission unit 13 creates an ISO image in which the lower layer information and the upper layer resource identification information corresponding to the virtual machine 20 indicated by the virtual machine identification information are embedded (step S103). (Step S104). Note that the ISO image is data in a format used when recording data on a recording medium such as a CD-ROM.

  In the virtual machine 20 to which the ISO image has been transmitted, the lower layer information receiving unit 21 receives the ISO image (step S105), reads the lower layer information and the upper layer resource identification information embedded in the ISO image, and sets the configuration file. It outputs to the production | generation part 23 (step S106). Note that the creation of an ISO image and the reading of information embedded in the ISO image are well known to those skilled in the art and are not directly related to the present invention, and thus detailed description thereof is omitted.

  When the lower layer information and the upper layer resource identification information are output from the lower layer information receiving unit 21, the setting file generation unit 23 reads the upper layer setting target information and the upper layer resource setting template stored in the storage unit 22. (Step S107), a setting file is generated (Step S108).

  The operation of the setting file generation unit 23 when generating the setting file will be described with reference to the flowchart shown in FIG.

  In FIG. 3, a case where an IP address assigned to a virtual machine that operates Tomcat, which is middleware, is set as an example in Apache, which is middleware that operates in a certain virtual machine, will be described.

  As described above, the ISO image in which the lower layer information and the upper layer resource identification information are embedded is transmitted from the lower layer management apparatus 10.

  FIG. 4 is a diagram illustrating an example of lower layer information. FIG. 5 is a diagram illustrating an example of higher layer resource identification information.

  FIG. 4 shows that the IP address assigned to the virtual machine that operates Tomcat is “192.168.10.3”. Further, FIG. 5 shows that upper layer resources necessary for processing are Apache and Tomcat.

  The setting file generation unit 23 acquires lower layer information and upper layer resource identification information embedded in the ISO file from the lower layer information reception unit 21 that has received the ISO image (step S201).

  Next, the setting file generation unit 23 reads the upper layer setting target information stored in the storage unit 22.

  FIG. 6 is a diagram illustrating an example of higher layer setting target information.

  As shown in FIG. 6, the upper layer setting target information corresponds to the upper layer resource identification information (Apache, Tomcat), the storage location of the upper layer resource setting template, the location of the setting file, and the setting file Indicates permission settings.

  The setting file generation unit 23 acquires the storage location of the upper layer resource setting template, the location of the setting file, and the permission setting of the setting file from the upper layer setting target information (step S202).

  Next, the configuration file generation unit 23 acquires the upper layer resource configuration template corresponding to the upper layer resource indicated by the upper layer resource identification information by accessing the storage location read from the upper layer configuration target information (Step S203). ).

  FIG. 7 is a diagram illustrating an example of a higher layer resource setting template.

  As shown in FIG. 7, in the upper layer resource setting template, as a setting for operating Apache, a host that receives provision of a port number of a data input / output port, a processing result, and the like (virtual machine that operates Tomcat) ) IP address and the like are described. Here, the IP address of the virtual machine that operates Tomcat varies depending on the environment for allocating lower layer resources. Therefore, the replacement character string [$ tomcat_ip_address] is described in the IP address of the virtual machine that operates Tomcat. As described above, in the upper layer resource setting template, the portion that changes depending on the environment in the setting of the upper layer resource is described by the replacement character string.

  Next, the setting file generation unit 23 extracts lower layer information corresponding to the replacement character string [$ tomcat_ip_address] described in the upper layer resource setting template. Since the lower layer information describes “tomcat_ip_address = 192.168.10.3”, the setting file generation unit 23 extracts the IP address “192.168.10.3” (step S204).

  Next, the configuration file generation unit 23 generates a configuration file by replacing the replacement character string [$ tomcat_ip_address] of the upper layer resource configuration template with the IP address “192.168.10.3” extracted in step S204. (Step S205).

  FIG. 8 is a diagram illustrating an example of a setting file.

  As shown in FIG. 8, in the upper layer resource setting template, the IP address “192.168.10.3” is described where the replacement character string is described. The replacement of the replacement character string is performed using, for example, a template engine using Perl's “Text :: Template” which is a programming language.

  Next, the setting file generation unit 23 arranges the generated setting file in the arrangement destination acquired in step S202 and sets the permission (step S206).

  Next, the setting file generation unit 23 determines whether or not the setting file has been generated for all upper layer resources that need to be generated (step S207).

  If the creation of the configuration file has not been completed for all upper layer resources (step S207: No), the configuration file generation unit 23 returns to the process of step S202.

  When the creation of the configuration file is completed for all upper layer resources (step S207: Yes), the configuration file generation unit 23 ends the process.

  As described above, according to the present embodiment, the lower layer management apparatus 10 generates and outputs lower layer information indicating the lower layer resource allocated to the virtual machine, and the virtual machine 20 performs virtual processing based on the lower layer information. Of the setting contents for the upper layer resource of the machine 20, a setting file is generated by replacing the replacement character string in the upper layer resource setting template partially described with the replacement character string, and the setting corresponding to the setting file is Go to the layer resource and perform processing according to the request.

  As described above, the virtual machine 20 automatically sets the upper layer resource only by outputting the lower layer information from the lower layer management apparatus 10. Therefore, even when horizontal division of labor provided by different operators for lower layer resources and upper layer resources is performed, upper layer resources are set with the relationship between upper layer operators and lower layer operators remaining loosely coupled. It is possible to construct and operate a virtual machine easily.

  The method performed in the information processing system of the present invention may be applied to a program for causing a computer to execute. In addition, the program can be stored in a storage medium and can be provided to the outside via a network.
