Is there any step by step guide on how to configure more than one bitcoin server that accepts bitcoin-rpc commands?
windows:
1. go to %appdata% (or wherever it's located for your OS)
2. make a copy of bitcoin folder, and rename it something like "bitcoin2"
3. put this in bitcoin.conf (create if it doesn't exist).
%appdata%\bitcoin:
rpcuser=user1
rpcpassword=mypassword1
%appdata%\bitcoin2
rpcuser=user2
rpcpassword=mypassword2
port=8335
rpcport=8334
4. open the folder where bitcoind.exe is installed, shift-right click the folder, "open command window here"
5. start bitcoind.exe
6. bitcoind.exe -datadir=%appdata%\bitcoin2
congratulations. now you have 2 servers running. rpc port for server 1 is 8332, server 2 is 8334
