This tutorial explains how to install a node with harvester in the [url=https://en.wikipedia.org/wiki/Raspberry_Pi]Raspberry Pi.
Note that you need a few items to turn on the computer:
1 [url=http://pt.aliexpress.com/wholesale?SearchText=raspberry+pi&catId=0&initiative_id=AS_20150418033525]Raspberry or [url=http://pt.aliexpress.com/wholesale?SearchText=banana+pi&catId=0&initiative_id=]Banana Pi ( It's almost the same thing and also works),
1 Power suply 5V 2A (from your mobile phone or can buy one [url=http://pt.aliexpress.com/wholesale?catId=0&initiative_id=SB_20150418034643&SearchText=raspberry+power]here)
1 Bluetooth USB Keyboard
1 MicroSD Card, [url=http://elinux.org/RPi_SD_cards]Here are a few that are compatible, only if you werent bad luck (like me)will have one that is not compatible.
The internet connection can be made via Ethernet cable or low power USB Wifi.
The connection to an image device can be done via HDMI or RCA in Rasp B / Banana Pi, and only HDMI from rasb B+ or above
Has been tested with all permissions, i wanted to test using limited, but gave mistakes, and I do not understand almost anything bash. ;(
If you want to do this, use [url=https://forum.ournem.com/technical-discussion/secure-nis-and-ncc-setup-on-linux/msg4107/#msg4107]this guide:
I tested and worked well in Rasp B (not B+).
Just download the Raspibian OS customized image of the [url=https://www.linuxsystems.it/raspbian-wheezy-armhf-raspberry-pi-minimal-image/]source or trhough [url=http://torcache.net/torrent/230FF534180EE71DB902A13ABE98ACB1EF9DBC54.torrent]torrent
use this command to record on the SD card:
dd bs=1M if=raspbian_wheezy_name.img of=/dev/sdX
*/dev/sdX is name of your SD card, use gparted to view it, also expand the system partition on the SD card and move swap partition to the end.
On Windows you can save the .img using the [url=http://sourceforge.net/projects/win32diskimager/]Win32 Disk Imager and move/expand partitions with [url=http://www.partitionwizard.com/free-partition-manager]MiniTool Partition Wizard .
Is recommended that you copy the updated NEM blockchain to /root/NEM/nis/data to synchronize faster. To do this will have to enter as super user on Linux or Windows.
Use[url=http://www.paragon-software.com/home/extfs-windows/] this program in windos in order to read and write partitions on Raspbian Filesystem
Use these [url=https://drive.bitcasa.com/send/pnpAcxsBnGB7ZCtj9RXkX6pElF5a1-j0ml075Hgfnd_f]scripts to configure the system for NEM, is scheduled for the version 0.6.28, but if outdated, just edit it and change the part of the version.
The first install java and configures NEM starting it;
The second is for if you want to use your privkey in term to harvest, will have to edit it using text editor to insert privkey before put SD on the Rasp
Now you should be all set to place the Raspberry in action.
Connect the Rasp and wait for the log on screen, use root as login with raspberry as password.
you will be in scripts folder, use
chmod +rx confignem.shto give the permissions to read and run, run
./confignem.sh Set location and keyboard input (default values are compatible in most cases) and wait until the screen to change the values of config.properties:
Remove hashes and set
nis.bootKey = preferably[url=https://forum.ournem.com/technical-discussion/using-remote-accounts-private-key-for-auto-boot/] privkey of your remote account
nis.bootName = any name to find cute
nis.unlockedLimit = 1 use 2 to 5, raspberry will dont support many haversters
Save using CTRL+X > Y > Enter
htop appears, check the total RAM you have, this system uses a 22 memory, so it is recommended to limit the use to not use the swap. Because write on SD cards is limited to a certain number of times, from then the data becomes permanent.
Press F10 to exit the htop and appears to config memory usage:
java -cp -Xms512M -Xmx1G cp
-Xms Is the minimum value to use, do not put very little to not crash.
-Xmx Is the maximum, put a value when added to the normal system use (which is a 25MB) is less than the total amount Memory of Raspberry.
I tested java -cp -Xms350M -Xmx400M cp and is working good.
Salve with ctrl+X > Y > enter
Now you're all set, NIS should start after the last action above.
To Harvest, wait for NIS verify all blocks, switch to the second terminal using Ctrl+Alt+F2
You can start harvesting using pre-configured script with your privkey, simply enter
Thus your node is online and picking !!
After a while you can check if it is visible to network here: http://nodeexplorer.com/
If public, see if port 7890 is not blocked by [url=https://forum.ournem.com/tutorials/configuring-your-network-to-reach-nem%27s-cloud/]firewalls. You can connect NCC of another computer via web, NCC is heavy for running in Raspberry.
