If there is no bitcoin-cli file in VPS server?

[wsxdrfv]

There  is only bitcoind file in VPS server's root folder,

and that is already running,

but there seems no bitcoin-cli, bitcoin-qt files.

In this situation, how to use bitcoin commands like [getinfo] [gettransaction] ?

You interact with bitcoind with the JSON-RPC protocol. So you can use cURL to do that. Or you can just copy a version of bitcoin-cli to your server. It's just a wrapper that can speak the JSON-RPC protocol, particularly for bicoind. It is a separate portable binary.
