Upgrade of a software product

An apparatus for upgrading a software product, the apparatus comprising a processor and a memory storing executable instructions that, in response to execution by the processor, cause the apparatus to:

• generate an upgrade package of the software product, the upgrade package including an installation file of the software product, a metadata file and one or more executable files, wherein the metadata file indicates a version of upgraded files of the software product, and a type of a disk file system, the version of the upgraded files being used to determine whether to upgrade the software product, wherein the one or more executable files are in a format of shell script files, and wherein the installation file of the software product has a size close to a size of the upgrade package;
• and
• execute the one or more executable files to perform operations for upgrading any one or all of optional components in the software product, including:
• unpack the installation file, wherein the installation file includes files of the software product with a latest version;
• add a disk file in the installation file to a virtual machine as a disk based on a file name indicated in the metadata file, the disk file including the upgraded files;
• mount the disk file to a mount point of the virtual machine, wherein the mount point is based on the type of the disk file system indicated in the metadata file;
• and
• provide a path to access the upgraded files based on the mount point and a folder path of the upgraded files indicated in the metadata file.

A computer-readable storage medium for upgrading a software product, the computer-readable storage medium being non-transitory and having computer-readable program code stored therein that in response to execution by a processor, causes an apparatus to:

• generate an upgrade package of the software product, the upgrade package including an installation file of the software product, a metadata file and one or more executable files, wherein the metadata file indicates a version of upgraded files of the software product, and a type of a disk file system, the version of the upgraded files being used to determine whether to upgrade the software product, wherein the one or more executable files are in a format of shell script files, and wherein the installation file of the software product has a size close to a size of the upgrade package;
• and
• execute the one or more executable files to perform operations for upgrading any one or all of optional components in the software product, including:
• unpack the installation file, wherein the installation file includes files of the software product with a latest version;
• add a disk file in the installation file to a virtual machine as a disk based on a file name indicated in the metadata file, the disk file including the upgraded files;
• mount the disk file to a mount point of the virtual machine, wherein the mount point is based on the type of the disk file system indicated in the metadata file;
• and
• provide a path to access the upgraded files based on the mount point and a folder path of the upgraded files indicated in the metadata file.
