Hi @Mengmeng YU ,
I believe you are using the wrong file. If you are just looking to add it as an app you can download the correct file here https://marketplace.atlassian.com/apps/1213632/jira-service-management/version-history
This will download an .obr file which can be uploaded as an application.
The background to this is that the .bin file is an installer, intended to be run by your operating system, to install or upgrade one of the application bundles (Core, Core + Software or Core + Service Management) from scratch, creating a new or upgraded service.
The .obr that Dirk refers to is just the application or app, in a parcel ready to install into an existing Jira service.
