Run Bitcoin and BitcoinCash in same server I use debian 9
I have compile 2 files:

bitcoinCashd -version
Bitcoin ABC Daemon version v0.16.2.0-6af5e93

bitcoind -version
Bitcoin Core Daemon version v0.15.1

So i need run in same server. Can some one help? 

maybe need rename some executable files and connected both wallets on different ports?

Maybe good step by step manual
The PORT (to receive data) for both of them is 8332 by default. So you must determine the PORT in the config file for one or both of them like this:

For BitcoinCash:

server=1
daemon=1
rpcuser=xxx
rpcpassword=zzz
rpcport=8355
port=6950


For Bitcoin:

server=1
daemon=1
rpcuser=aaaaaa
rpcpassword=bbbb
rpcport=8320
port=5380


Don't forget to allow the ports by firewall and specify different data directories for them.
