Bitcoind 0.9.1 on RaspberryPi

[levino]

Hey guys. As the other threat seems to be dead I start a new one:  https://bitcointalk.org/index.php?topic=191729.msg4850024#msg4850024

Did anyone successfully set up a STABLE full node on a raspberrypi?

I compiled it using a couple of flags: --disable-wallet --with-cli --without-gui in hope to save on memory. Any other recommendations?

Thanks

You got it compiled? I ended up using 0.8.6 because I couldn't compile (missing makefile.unix) and I also had no joy via github.

Anyway, some other things I did:


Make some room:

Code:

apt-get purge -y lxappearance lxde lxde-common lxde-core lxde-icon-theme lxinput lxpanel lxpolkit lxrandr lxsession-edit lxshortcut lxtask lxterminal xinit xserver-xorg xserver-xorg-video-fbdev wolfram-engine desktop-base desktop-file-utils gnome-icon-theme gnome-themes-standard leafpad menu-xdg omxplayer scratch xarchiver zenity lightdm midori tk8.5 pcmanfm blt idle idle3 python-tk python3-tk dillo openbox 

Code:

 apt-get autoremove -y

Code:

 apt-get autoclean -y 

Code:

 apt-get clean -y

 

Removed unused locales:

Code:

sudo apt-get install localepurge 
sudo localepurge

Installed some:

Code:

apt-get install -y screen watchdog trickle fail2ban ufw 

Some of the things mentioned in this script are useful:

Some pointers here (although I didn't follow everything to the t):

And lastly I used rsync to copy over the block data via ssh. Or you could use the bootstrap torrent (search the forum) and copy that over.


I have no issues with memory. Free memory is always low (~15 MB), but it doesn't crash.

I bought the ODROID. I will keep you postet when it arrives.

0.9.1 compiled fine btw. Just get it with git, run the scripts and compile. The issue with the missing file has been fixed I guess.

Cheers

Oh, yes, please keep me posted on the Odroid! It looks like it will be the end of any storage capacity woes.

I only tried a few days ago and had no joy via git either. If I recall correctly it was an libboost related error. I'll try again one day. Unfortunately the RPi is now tied up doing something else

I followed this guide to compile:

http://bitcoin-austria.at/artikel/full-bitcoind-node-debian-7-server

It is in German, but the commands are universal

Important thing to do is to increase the Swapfile-size to 500 MB before compiling like in this guide: http://blog.macoymejia.com/2014/01/27/compiling-bitcoind-on-raspberry-pi/

That's pretty much what I did too. Still not sure what happened.

As the article mentions the band-with limitation (in their example) of the VPS..., one thing I wanted to try out was the trickle command, but haven't gotten around to it. You can limit up-/ download speeds with it. So, knowing your VPS is limited to 400 GB, you calculate your speed to transfer that amount of data in a month and set your trickle values accordingly. 

Since you are interested in nodes... Have you looked at other implementations such as BTCD or libbitcoin?

Just remembered: If you worry about debug.log write cycles, run with -printtoconsole.

Thanks for the tip. But there are so many services that log to files on the sd card. I don't think that whether or not bitcoin logs in one as well makes any difference...

Okay, I have to ask:  what's the hash rate on a Raspberry Pi if you set generate coins to true?
