I'm definatly not a *nix guru. I'm sadly a noob, who loves RPi and XMR - Anyway the cloning and compliling (make -j2 release-arm7) is not perfromed as root. For me I used the std ubuntu login. You can delete the bitmonero and then from git clone pick up the instructions again.

RPi2 0.9.1.0 Monero Node
Kit List
RPi2
Powered USB Hub Manhattan 7-port USB 2.0 - Powers the SSD
Yes sadly the SSD makes all the difference with your RPi2
I’ve fried numerous SD cards and USB keys……
Download the ubuntu image for RPi2 2015-04-06-ubuntu-trusty.zip
Follow these instructions for getting UBUNTU on to your SSD or USB, remember you're installing ubuntu not wheezy!
At this point I get the RPi2 to a point that I can disconnect the monitor, keyboard etc
I also MAC reserved the RPi2's IP Address via DHCP (On your router or DHCP server, so it has a consistent IP Address)
So a few tasks are required first
If you're running from a USB / SSD external drive, Now is the time to edit /etc/FSTAB to reflect the new root drive
Or sudo apt-get upgrades will complain it cannot find /dev/mmcblk0p2
fstab changes
proc /proc proc defaults 0 0
/dev/sda2 / ext4 defaults,noatime 0 1
/dev/mmcblk0p1 /boot vfat defaults 0 2
#/dev/mmcblk0p2 / ext4 defaults,noatime 0 1
# a swapfile is not a swap partition, so no using swapon|off from here on, use dphys-swapfile swap[on|off] for that
I reboot at this point
sudo reboot
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install openssl-server
sudo apt-get install screen
(for multiple sessions) Screen is great, you can disconnect from the session and know it's still running fine Ctrl+Alt+d*
sudo halt -p
This powers it off so you can disconnect monitor, keyboard etc and SSH in from where you would normally
power up and ssh on to your RPi2 (or you can remain sitting infront of it??)
ssh [email protected]
NOW CHANGE THE DEFAULT PASSWORD!
ubuntu@ubuntu:~$ passwd
Changing password for ubuntu.
(current) UNIX password:
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Change time zone to your timezone
sudo dpkg-reconfigure tzdata
sudo apt-get install dphys-swapfile
Installs the swap file, I left it as a default install)
Thats the prep of the RasPi2 with ubuntu complete
sudo reboot
ssh back in to set up environment These packages are for the ability to build from source
sudo apt-get install git vim build-essential doxygen miniupnpc cmake
These packages are to install the dependencies for bitmonero
sudo apt-get install libboost1.55-all-dev libevent-dev libunbound-dev liblmdb-dev libdb++-dev libdb-dev
Copy all the required source files to your RPi2
git clone https://github.com/monero-project/bitmonero.git bitmonero
switch into that dir
cd bitmonero/
You're now ready to compile
make -j2 release-arm7
If you're feeling brave use -j4 to use all of your RPi2's cores
It took just under 2 hours to compile for me (SSD don’t forget)
sudo reboot
you’re ready to launch now
cd bitmonero/build/release/bin
./bitmonerod
This defaults to BerkeleyDB
:-)
The launch syntax I am now using is
./bitmonerod --rpc-bind-ip 0.0.0.0 --rpc-bind-port 5012
I start my wallet with this syntax
./simplewallet --daemon-address 192.168.0.XX:5012 --wallet-file ./wallet.bin
I like to backup the blockchain once, when it's fully synced, to save time if I have a disaster. Being a Mac user.... This is the terminal command I use
rsync -avz --timeout=50 [email protected]:~/.bitmonero/ /Volumes/G-DRIVE/wedgy2kBackups/Cryptos/UbuPiBup
I've started syncing the blockchain with no additional commands (my Internet connection is 40Mbps)
Block Sync Start 26/01/2016 22:52
Had to restart this as BerkeleyDB and it took aprx 26 Hours
Please point out any errors omissions etc. Or ask some questions?
Hopefully this will be of use to some one.
A big thanks to saddam, smooth,NoodleDoodle and fluffypony
Hi,I followed to above instructions and while i started the ./bitmonerod i got this error:

I compiled it as root user. I tried several times but i get always the same error. Do someone know how i can solve it?
Thanks a lot
These are the edits I made when failing to get lmdb to work - but I'm not done yet!

Annoyingly this died during syncing at

So I'm wrestling with it currently
I'll edit and post updates....
Edit 27/01/2016 23:50
Copied over the fully synced lmdb directory from my Mac via SFTP, ensured file permissions were same as originals and now working ok - (Work around - ongoing)
Edit 28/01/2016 00:30
That actually hasn't worked, its like the RPi2 cannot write to the data.mdb file even set to 777 :-(
Edit 29/01/2016 23:00
As I need this up and running I've synced it as a BerkeleyDB and it works fine - took aprx 26hours to sync.
When I have more time and less need, I'll wrestle with the lmdb - but it was like as an LMDB it could not write to the drive after a certain file size (202234 Blocks) despite being on a 256GB SSD drive.
I'll probably try a few different RPi2 images once I have a completed lmdb and BerkeleyDB Blockchain to play with.
