user31465: I followed the great answer here how to install bitcoin legacy and bitcoin cash on the same ubuntu server?
and installed bitcoinCash client to my ubuntu server.
Now I have both binaries available but they both work on same configs and same blockchains as I see. 

There supposed be a way how to tell bitcoinCash client to download its own chain and use its own keys, but I cant figure out where those setup files for bitcoinCash are located and how to change them.
Could anyone help pls?

user63569: You can create a new username for Bitcoin cash or change default directory.
adduser BitcoinCashUser 

su BitcoinCashUser

BitcoinCashd -daemon

Now make sure it has own directory 
cd ~/.bitcoin

You should find the files in here.

Note: kill bitcoin-cash before start it again. 
ps ax | grep bitcoinCashd
kill -9 <Process ID>
