Hello everyone,

I have some progress to report on setting up a staker on the raspberry-pi. Silk runs pretty smoothly with about 9.7% memory use and between 15-30% cpu usage on my raspberry-pi 2. I also installed it on my model 1, and it seems also to be working well. Staking works and my machine earned me some SLK over night

I know @prometheusX has posted a tutorial already, but there were still some steps left out.
So here is my raspberry-pi staker building instructions that should be quite accessible for everyone.

Raspberry PI SILK STAKER

Preparing the raspberry-pi
* Get the latest raspbian-lite image from the Raspbian download page
* Flash SD card according to the official intructions
* Insert SD card into pi, connect LAN, power raspberry pi
* Find IP address of raspberry
*

Code:

ssh

into your raspberry

Code:

ssh pi@

The standard password is "raspberry"
* Configure your raspbery by running

Code:

sudo raspi-config

:
* Expand filesystem
* Change password for the user pi
* Overclock to your likings (useful for compilation, see below, but not really required for running the very slick silk client)
* Under "Advanced options", you can set the shared memory for the GPU to only 16MB. We won't be running any graphical applications in any case
* Edit swap file size to 512MB (see also this guide)
*

Code:

sudo nano /etc/dphys-swapfile

* Change the default value of

Code:

CONF_SWAPSIZE=100

Code:

CONF_SWAPSIZE=512

* Reboot the pi

Installing the prerequisistes
* After reboot, login again and install the basic dependencies needed for Silk. All details are on the SilkNetwork github page
* Refresh the list of repositories, and upgrade (you can get a cup of tea in the meanwhile)

Code:

sudo apt-get update

Code:

sudo apt-get upgrade

Code:

sudo apt-get dist-upgrade

* Install the basic packages

Code:

sudo apt-get install build-essential libtool autotools-dev autoconf pkg-config libssl-dev libcrypto++-dev libdb++-dev libboost-all-dev

* Install git

Code:

sudo apt-get install git

* Set root password

Code:

sudo passwd root

Build Berkeley DB 4.8
* Pick some path to install Berkeley DB4.8 (DBD). Here, we just install it a folder called "BDB4.8"

Code:

mkdir BDB4.8

Code:

cd BDB4.8

* Now that we are in the directory where we will build BDB, let's define an environement variable that we will use later

Code:

BDB_PREFIX=$(pwd)

* Fetch the source and verify that it is not tampered with

Code:

wget 'http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz'

Code:

echo '12edc0df75bf9abd7f82f821795bcee50f42cb2e5f76a6a281b85732798364ef db-4.8.30.NC.tar.gz' | sha256sum -c

Code:

tar -xzvf db-4.8.30.NC.tar.gz

* Build the library and install to our prefix (get a small cup of tea)

Code:

cd db-4.8.30.NC/build_unix/

Code:

../dist/configure --prefix=$BDB_PREFIX --enable-cxx --with-pic

* Build and install (I had no problems with sudo, contrary to the other tutorial posted)

Code:

make

Code:

sudo make install

Build Silk-Core
* Clone Silk-Core using git

Code:

git clone https://github.com/SilkNetwork/Silk-Core.git

Code:

cd Silk-Core

* Generate installation files

Code:

./autogen

* Configure installation

Code:

./configure --without-gui --disable-tests LDFLAGS="-L${BDB_PREFIX}/lib/" CPPFLAGS="-I${BDB_PREFIX}/include/"

* Compile and install

Code:

make

Code:

sudo make install

Running a Silk-Node
* Start the Silk Daemon

Code:

silkd

. This will be always running in the background, and you will interact with it via sending rpc commands from using

Code:

silk-cli

. Running this for the first time will generate the hidden folder

Code:

~/.silk

Code:

silkd --daemon

* You will receive an error message, telling you that you have to change some values in the (automatically generated) file

Code:

~/.silk/silk.conf

Code:

nano ~/.silk/silk.conf

* Now change

Code:

listen=1

Code:

listen=0

(and, if you want, you can change the rpcuser and its password) and safe the file (

Code:

)
* Try to start the dameon again. This time, it should work.

Code:

silkd --deamon

* Now you are ready to interact with the daemon using

Code:

silk-cli

Interacting with the Daemon
* For an overview of commands use

Code:

silk-cli help

* Check the status

Code:

silk-cli getinfo

* If you see an error "wallet loading" then don't worry: you were simply too fast and the wallet file is still building. Give it two minutes and try again

Staking
* On your main machine, create a new address that you want to use for staking. If you want, use the splitcoin feature to generate this address already with a multitude of inputs.
* Now on the QT-Wallet on you main machine, go to Tools/Debug Console and get the private key of this staking address (Note: Wallet needs to be unlocked for that)

Code:

dumpprivkey "

* Write down/copy the the private key
* Go to your Raspberry and import the private key (you can optionally provide a label for this address in the wallet)

Code:

silk-cli importprivkey ""

Happy staking!
That should be all. If you have questions, message me or answer. I will be posting some proper benchmarks later. @Devs: if you want this guide for the docs, I am happy to provide. @fellow silkers: If you find this helpful (and especially, if you have succeeded in setting up your staker), consider buying me a beer or a cup of tea:

Keep On Marching!

When I get to ./autogen for silk core - no such file or dir. What do I do? Thanks
