If you're using Bitcoin-Qt instead of bitcoind, you need to enable RPC interface in config:
~/.bitcoin/bitcoin.conf
server=1
rpcuser=rpcuser
rpcpassword=somepasswordhere
(you might want to edit rpcpassword part). Create this file and restart bitcoin-qt. (Note that you don't need -reindex option, but you need other options... Except -daemon, it is useless in this case.)
