Abstract

A method and apparatus of installing an operating system are provided. According to an example of the method, a server reads an image file of an operating system from a system providing device, wherein the image file comprises address information corresponding to an automatic response script file, and the automatic response script file is not stored at a position corresponding to the address information. The server receives the automatic response script file provided by the system providing device in response to that the reading by the server advances to the position corresponding to the address information. The server installs the operating system by using the automatic response script file.

First claim

The invention claimed is:

1. A method of installing operating system, comprising:
reading, by a server, an image file of an operating system from a system providing device, wherein the image file comprises address information of an automatic response script file, and the automatic response script file is not stored at a position corresponding to the address information, and wherein the system providing device maintains a mapping relationship between the server and the automatic response script file, when reading the image file, the server sends identification information of the server and current reading position information to the system providing device, so that the system providing device acquires the automatic response script file corresponding to the identification information when the current reading position information indicates that the reading by the server advances to the position corresponding to the address information;
receiving, by the server, the automatic response script file which is provided by the system providing device in response to that the reading by the server advances to the position corresponding to the address information and based on the mapping relationship; and
installing, by the server, the operating system by using the automatic response script file.

2. The method according to claim 1 , wherein the address information of the automatic response script file comprises a file header address and a file size of the automatic response script file.

3. The method according to claim 1 , wherein, the image file comprises an ISO image file.

4. A method of installing operating system, comprising:
providing, by a system providing device, an image file of an operating system to a server, wherein the image file comprises address information of an automatic response script file, and the automatic response script file is not stored at a position corresponding to the address information, and wherein the system providing device maintains a mapping relationship between the server and the automatic response script file;
acquiring, by the system providing device, the automatic response script file in response to that the reading by the server advances to the position corresponding to the address information of the automatic response script file and based on the mapping relationship, wherein, acquiring the automatic response script file in response to that the reading by the server advances to the position corresponding to the address information of the automatic response script file, comprises: determining, by the system providing device, whether the reading by the server advances to the position corresponding to the address information based on identification information of the server and current reading position information which are received from the server; and acquiring, by the system providing device, the automatic response script file corresponding to the identification information according to a mapping relationship between server and automatic response script file in a case that the current reading position information indicated that the reading by the server advances to the position corresponding to the address information, and
providing, by the system providing device, the automatic response script file to the server so that the server installs the operating system by using the automatic response script file.

5. The method according to claim 4 , wherein the address information of the automatic response script file comprises a file header address and a file size of the automatic response script file.

6. The method according to claim 4 , wherein, determining whether the reading by the server advances to the position corresponding to the address information based on identification information of the server and current reading position information which are received from the server, comprising:
acquiring, by the system providing device, an offset header address and a content length of content to be read by the server, according to the current reading position information; and
determining, by the system providing device, that the reading by the server is advancing to the position corresponding to the address information when the offset header address is greater than or equal to the file header address and a sum of the content length and the offset header address is equal to or less than a sum of the file header address and the file size.

7. The method according to claim 4 , wherein, the image file comprises an ISO image file.

8. An apparatus of installing operation system, comprising:
a processor;
a non-transitory storage medium storing with machine executable instructions,
wherein, by executing the machine executable instructions, the processor is caused to:
read an image file of an operating system from a system providing device, wherein the image file comprises address information of an automatic response script file, and the automatic response script file is not stored at a position corresponding to the address information, and wherein the system providing device maintains a mapping relationship between the apparatus and the automatic response script file, wherein when reading the image file, the machine executable instructions further cause the processor to: send identification information of the server and current reading position information to the system providing device so that the system providing device acquires the automatic response script file corresponding to the identification information when the current reading position information indicates that the reading by the server advances to the position corresponding to the address information;
receive the automatic response script file which is provided by the system providing device in response to that the reading by the server advances to the position corresponding to the address information and based on the mapping relationship; and
install the operating system by using the automatic response script file.

9. The apparatus according to claim 8 , wherein the address information of the automatic response script file comprises a file header address and a file size of the automatic response script file.

10. The method according to claim 8 , wherein, the image file comprises an ISO image file.
