Installing BitcoinD when Bitcoin-qt is already installed (Ubuntu 12.04)?

[JackH]

Are there any complications installing BitcoinD when Bitcoin-qt is already installed? I am running Ubuntu 12.04 and wanted to know if it gives any problems to have both installed on the same machine.

I wanted to install BitcoinD in order to play around with some of the RPC commands via Python.

shouldnt be a problem, just stop bitcoin-qt when you go to run bitcoind as bitcoin-qt will be using the database.

On ubuntu if you have the PPA installed it should just be a matter of installing from apt.

apt-get install bitcoind

or

sudo apt-get install bitcoind

Will installing BitcoinD require to re-download the entire blockchain, or does it "know"?

[TechnoBibble]

no, if you install it as the same user as bitcoin-qt the blockchain will still be downloaded in ~/.bitcoin/ usually or whetever path you specified.

Also as an aside, you will need to add/edit your .conf file. I can't remember if the new version populates it automatically for you or not.

EDIT: Also try the bitcoin-cli. The daemon-rpc calls will eventually be obsolete.

No, Bitcoind will search for blockchain on the directory the same as the bitcoin-qt one. If you downloaded it to other places, run this:

Code:

bitcoind -datadir=insert directory here

Before running bitcoind, you will also need a conf file. Detailed explaination here:http://we.lovebitco.in/bitcoin-qt/configuration-file/
