replyAfter I installed it, there is only this package at the beginning. There is also a package called nginx1.1.5 that was downloaded. It is just a simple nginx package that is used when starting it on its own, but I don’t know how it came about. It doesn’t seem to be downloaded. Thank you teacher for the recovery
Where does the nginx file here come from?

You can try installing it yourself
