Then, the environment setting script execution unit 203 executes the command specified by the setting execution unit 104, and sets the parameter value specified by the setting execution unit 104 in the virtual machine.
Further, the network setting unit 204 uses the VLAN switching unit 102 to perform network settings such as changing the connection destination of the virtual NIC port.
The image file operation unit 205 executes image operations such as storage and copying of image files of virtual machines.

The environment setting script a 107a and the environment setting template a 108a in FIG. 3 are examples of the environment setting script 107 and the environment setting template 108, respectively, for example, the environment setting script 107 and the environment setting template 108 for the virtual machine A121.
In the environment setting script a 107 a, a command execution program 212 is defined for the command 211.
For example, for the “FileItem” command, “SetFileItem” for defining file items is defined as the command execution program 212, and for the “DBparam” command, “SetDBparam” for defining the DB setting file is defined. ing.
In the environment setting template a108a, for example, in the “FileItem” command, “file name”, “item name”, and “data” are defined as parameters A222a, paramB223, paramC224, and in the “DBData” command. “ID / password”, “table name”, and “data file (csv)” are defined.
Actually, the setting execution unit 104 selects the setting command, sets the value of the parameter corresponding to the setting command, and executes the information, which is output as the environment setting information a109a.
In the environment setting information a109a, a command name 231 for specifying a command to be executed and parameter values for the command are set corresponding to paramA232, paramB233, and paramC234. The number of parameters is changed according to the defined information.
That is, the environment setting information a109a indicates the command executed for the virtual machine A121 and the parameter values set for the virtual machine A121.
Note that the values of the command name 231, paramA 232, paramB 233, and paramC 234 of the environment setting information a 109 a are described using the values of the command name 221, paramA 222, paramB 223, and paramC 224 of the environment setting template a 108 a as templates.

FIG. 4 shows an example of a setting execution screen that the setting execution unit 104 displays on a display device (not shown).
The operator of the multi-tenant environment setting apparatus 101 can specify parameter values on the setting execution screen shown in FIG.

A setting execution screen 301 is an example of a screen for executing environment setting, and can be selected from the script list 304 and the parameter list 305 displayed in the list by reading the environment setting script 107 and the environment setting template 108.
When a selection is made in the script list 304, the corresponding parameter is displayed in the parameter list 305, so the operator inputs the value of the necessary parameter.
Then, a command set button 306 defines a set of environment setting commands to be executed by adding, changing the order, or deleting the command list 303.
Information on this command set is output as environment setting information 109.
In the environment setting information list 302, when a new output is made, “new” is selected, a save button 308 is pressed, and a file name is designated.
When executing the setting using the already defined environment setting information 109, the operator selects the corresponding environment setting information 109 from the environment setting information list 302, selects the environment setting information selection button 311, and executes the setting. This is executed by pressing a button 307.
When executing in command units, the command selection button 313 is selected. When executing a set of commands defined in the command list, the command list selection button 312 is selected, and then the execution button 307 is pressed.

In this embodiment, the environment setting for the virtual machine A 121 is first performed, and then the environment setting for the virtual machine B 131 is performed.
In the environment setting for the virtual machine B131, in order to improve the efficiency of the setting work, the environment setting for the virtual machine B131 is performed using the environment setting information a109a indicating the contents of the environment setting for the virtual machine A121.
Therefore, in the environment setting for the virtual machine B 131, the operator selects the environment setting information a109a in the environment setting information list 302.
Then, according to the input from the operator, the setting execution unit 104 performs editing to change only the parameters that need to be changed for the virtual machine B 131 among the parameters included in the environment setting information a 109a.
The environment setting information 109 after editing by the setting execution unit 104 is referred to as environment setting information b 109b.
Thereafter, the environment setting script execution unit 203 executes the environment setting script a 107a using the parameter values indicated in the environment setting information b 109b, and sets the parameter values indicated in the environment setting information b 109b in the virtual machine B 131. .

FIG. 5 is a flowchart showing a flow of an operation of switching the VLAN of the virtual machine using the VLAN switching unit 102.
FIG. 6 is a flowchart showing the flow of the environment setting operation for the virtual machine A121.
FIG. 7 is a flowchart illustrating a flow of an environment setting operation for the virtual machine B 131.

Next, the operation will be described.
First, the operation of the VLAN switching unit 102 will be described using the flowchart of FIG.

When connecting to the virtual machine from the multi-tenant environment setting apparatus 101, first, the VLAN switching unit 102 acquires the number of the virtual machine to be connected from, for example, an operator or a predetermined file (S101).
Here, it is assumed that the number of the virtual machine A121 is acquired.
Next, the VLAN switching unit 102 acquires whether the execution state of the virtual machine is at the time of installation or at the time of operation (S102).
The operating state is a state after the environment setting is completed.
If it is during installation (YES in S103), the connection port in the virtual switch 141 of the virtual NIC 123 of the virtual machine A121 is set as the installation port A125 (S104), and the VLAN switching unit 102 connects the virtual NIC 123 to the installation port A125, Enables communication with the installation VLAN.
On the other hand, if it is not installed but operating (NO in S103), the connection destination port is set to the operating port A124 (S105), and the VLAN switching unit 102 connects the virtual NIC 123 to the operating port A124 to communicate with the installation VLAN. enable.
When a connection is made from the multi-tenant environment setting apparatus 101, a VLAN tag is designated based on the connection destination virtual machine number and execution status (S106, S107).
That is, at the time of installation, the network setting unit 204 of the setting command unit 103 specifies the installation port A125 of the virtual machine A121 in the VLAN tag of the packet transmitted to the virtual machine A121 (S106).
If it is in operation, the network setting unit 204 designates the operation port A124 of the virtual machine A121 in the VLAN tag of the packet transmitted to the virtual machine A121 (S107).
Here, the case of connecting to the virtual machine A 121 has been described, but the same applies to the case of connecting to the virtual machine B 131.

  Next, an example of setting the first device for the virtual machine A 121 will be described with reference to the flowchart of FIG.

(1) The VLAN switching unit 102 connects the virtual NIC 123 of the virtual machine A121 to the installation port A125 and connects from the multi-tenant environment setting apparatus 101 to the virtual machine A121 using the installation VLAN (S201).
That is, S101 to S104 shown in FIG. 5 are executed for the virtual machine A121.
As described above, a common private address is specified for the virtual machine A 121 and the virtual machine B 131 for the installation VLAN.

  (2) Next, an image file 122 in which the OS / application is installed in the virtual machine A 121 is created and transmitted to the multi-tenant environment setting apparatus 101 through the installation VLAN. In the multi-tenant environment setting apparatus 101, the image file operation unit 205 The image file 122 is stored in the image file storage unit 116 as the image file 106, and the image file storage unit 116 stores the image file 106 (S202).

(3) Next, after installing an OS or an application in the virtual machine A 121, the setting execution unit 104 checks whether a command for performing environment setting is defined as a setting command (S203). A command is set in the environment setting script 107 and a parameter for the command is set in the environment setting template 108 (S204).
Commands can be created and added as needed.

(4) Next, the operator performs DB table information and initial data of the virtual machine A 121, and environment settings (customization settings) necessary for the application (S205).
At this time, on the setting execution screen 301, it is possible to select and execute an operation for changing the value of the setting file of the OS or application displayed in the script list 304 from the environment setting script 107.
Since necessary parameters corresponding to the selected command are displayed in the parameter list 305 from the information of the environment setting template 108, the operator defines parameter values according to the information.
When all the definitions are completed, the command setting button 306 is used to specify addition or change of order in the command list 303.
In the process of S205, the command of the environment setting script 107 is executed, a packet including the parameter value is transmitted to the virtual machine A 121 by the installation VLAN, and the parameter value defined by the operator on the setting execution screen 301 is the virtual value. Set to machine A121.
The packet transmission here is performed by designating the installation port A125 of the virtual machine A121 in the VLAN tag as described in S106 of FIG.

(5) If the environment setting continues, repeat from S203 (S206).
When the environment setting is completed, the process proceeds to the next process.

  (6) After completing all customization settings, the VLAN switching unit 102 switches the connection destination of the virtual NIC 123 to the operation port A124 (S207).

  (7) Finally, the setting execution unit 104 generates information (parameter values specified by the operator) set in the command list 303 on the setting execution screen 301 as environment setting information a109a, and the generated environment setting information a109a Is output to the environment setting information storage unit 119, and the environment setting information storage unit 119 stores the environment setting information a109a (S208).

  Next, an example in which the expansion to the second and subsequent virtual machines is expanded to the virtual machine B 131 will be described with reference to the flowchart of FIG.

(1) The VLAN switching unit 102 connects the virtual NIC 133 of the virtual machine B131 to the installation port B135, and connects from the multi-tenant environment setting apparatus 101 to the virtual machine B131 using the installation VLAN (S301).
That is, S101 to S104 shown in FIG. 5 are executed for the virtual machine B131.

(2) Next, the setting execution unit 104 uses the image file operation unit 205 of the setting command unit 103 to copy the image file 106 to the virtual machine B 131 and set it as the image file 132 (S302).
In other words, the image file operation unit 205 transmits the image file 106 to the virtual machine B 131 as the image file 132 in the installation VLAN, and the virtual machine B 131 executes the image file 132 to install the OS and applications.
At this time, the multi-tenant environment setting apparatus 101 was originally connected to the virtual machine A 121 via the installation VLAN, but since the installation VLAN specifies a common address, the image file 132 on the virtual machine B 131B can be used as it is. Connection is also possible (connection to an OS executed by the image file 132 is possible).

(3) Next, the operator generates environment setting information b109b for designating commands and parameters to be executed when performing customization settings for the image file 132 on the setting execution screen 301 (S303).
The environment setting information b109b is created based on the environment setting information a109a by changing parameter values according to customization to the virtual machine B131.
That is, the operator selects the environment setting information a109a in the environment setting information list 302 on the setting execution screen 301, and the setting execution unit 104 is for the virtual machine B131 among the parameters included in the environment setting information a109a according to the input from the operator. Edit to change the value of only the parameter that needs to be changed to generate the environment setting information b109b.

(4) When the environment setting information b109b is generated, the operator presses the execution button 307 on the setting execution screen 301, and the environment setting script execution unit 203 executes the environment setting script a107a to set the necessary environment settings for the virtual machine B131. (Customize setting) is performed (S304).
In the process of S304, the command of the environment setting script a107a is executed, a packet including the parameter value is transmitted to the virtual machine B131 by the installation VLAN, and the parameter value indicated in the environment setting information b109b is set in the virtual machine B131. Is done.
The packet transmission here is performed by designating the installation port B135 of the virtual machine B131 in the VLAN tag as described in S106 of FIG.

(5) After completing all the customization settings other than the network settings, the network setting unit 204 performs the network settings.
Customize settings to the network setting file are performed in the same way as other processes.
After the setting is completed, the VLAN switching unit 102 switches the connection destination of the virtual NIC 133 to the operating port B134 (S305).

  Thereafter, the multi-tenant user designates the connection to the operating VLANs of the virtual machine A 121 and the virtual machine B 131 via the router 161, and can connect to the application after the environment setting.

As described above, in this embodiment, the environment setting for a plurality of virtual machines is performed using an installation VLAN in which a common communication address is used for the plurality of virtual machines.
For this reason, when the environment setting for the virtual machine B 131 is performed after the environment setting for the virtual machine A 121, the connection to the virtual machine B 131 is performed simply by switching the connection destination virtual port to the installation port B 135 for the virtual machine B 131. Therefore, there is no need to perform special communication settings for connection to the virtual machine B131.
For this reason, the environment setting of the virtual machine B 131 can be performed following the environment setting of the virtual machine A 121, and no special communication setting is required for connection to the virtual machine B 131. The environment setting for the virtual machine B 131 can be performed by the environment setting information 109b obtained by editing the environment setting information a 109a.

As described above, according to the present embodiment, the first virtual environment is installed without performing OS or application installation when setting the environment for the same environment but with different setting values and initial data for each tenant. An image file created on a machine is expanded, and an efficient expansion operation can be performed by changing only a part of different parts.
The setting command unit 103 can be expanded to include customization commands, and by increasing the number of commands, various functions can be executed by scripts.
Furthermore, by preparing the environment setting template 108 according to the command in advance, it is possible to cope with the automatic execution of complicated commands.

In this embodiment,
In the multi-tenant environment where applications are deployed to multiple companies, the multi-tenant environment setting method that enables the common setting of service application environment settings with the following means and enables automatic execution by the administrator was explained.
(A) an installation VLAN environment for performing an installation operation on a virtual machine, a VLAN environment for operation, and a VLAN switching unit thereof;
(B) a setting command part for setting the environment;
(C) Generate setting information for other tenants from the setting using the setting command part according to the script or setting information template and the template, and further, in the installation VLAN environment, the environment to the virtual machine according to the script and the environment setting information A setting execution unit that executes setting and sets the operation VLAN environment by the VLAN switching unit.

Finally, a hardware configuration example of the multi-tenant environment setting apparatus 101 shown in the present embodiment will be described.
FIG. 8 is a diagram illustrating an example of hardware resources of the multi-tenant environment setting apparatus 101 illustrated in the present embodiment.
