= '''Instruções para compilar a edição Raspberry Pi 3 Headless''' =

Este guia abrange tudo o que você precisa saber para configurar uma carteira de stake e um nó de transações anônimas enigma portátil.


Se você seguir os passos por ordem, você terá uma carteira CloakCoin em funcionamento e terá na palma da sua mão o poder de suportar a rede CloakCoin.

'''Pré-requisitos'''
<ol>
<li> Raspberry Pi 3</li>
<li> Cartão 8Gb SD (recomendado um class 10)</li>
<li> Fonte de alimentação 5V 2A</li>
<li> Pen USB 2Gb para partição SWAP( Recomendado USB 3.0)</li>
<li> Ligação internet cabeada</li>
<li> Café</li>
</ol>



== Install a arm64 OS on the Raspberry Pi and setup a SWAP partition on a USB drive. == 


Pi64 is an 64-bit OS for the Raspberry Pi 3. It is based on Debian Stretch and backed by a 4.11 Linux kernel.
<ol>
<li>Download pi64 lite from:
<br>
::https://github.com/bamarni/pi64/releases/download/2017-07-31/pi64-lite.zip
<li>To write the Pi64 image into the SD card, we are going to use Etcher, download etcher for your platform here:
<br>
::https://etcher.io/
<li>Execute Etcher, then click on ''''select image'''' and select the Pi64 image you donwloaded earlier, then ''''select drive'''' for the SD card you are going to use on the Pi, then click ''''Flash'''!'. Wait for the ''''flash completed!'''' message and then you have the SD card ready  to use on the Raspberry Pi.
<li>Insert the SD card on the Raspberry Pi and power it up.
During first boot the installation process will continue for a few minutes, then the Raspberry Pi will reboot and you'll be ready to go.
The default user is pi and its password raspberry, it has passwordless root privileges escalation through sudo.
On the lite version, SSH is enabled by default.
<li>Change the pi user password by issuing the command: 
::<code>passwd</code>
<li>Update Pi64 packages lists by typing:
::<code>sudo apt-get update</code>
<li>Install a text editor:
::<code>sudo apt-get install nano</code>
<li>To create a swap partition on the USB drive, create an empty partition that should have no holes. You can then format this partition with:
::<code>sudo mkswap /dev/sdX</code>
replacing /dev/sdX with your partition (type the command <code>dmesg</code> to identify your USB drive, on my case it is sda1). 
<li>Mount this partition as swap with:
::<code>sudo swapon -U UUID</code>
where UUID is that of your /dev/sdX as read from this:
::<code>sudo blkid /dev/sdX</code>
Bind your new swap in /etc/fstab by editing fstab with:
::<code>sudo nano /etc/fstab</code>
Adding this line (replace xxx with the UUID of your sdX):
::<code>UUID=xxx    none    swap    sw      0   0</code>
<li>Reboot the system with:
::<code>sudo reboot</code>
<li>To vizualize the newly added swap partition type:
::<code>free -h</code>
</ol>




==  Setup the building enviroment ==


<ol>
<li>Install the dependencies and required apps by issuing the following commands:</li>
::<code>sudo apt-get update</code>
::<code>sudo apt-get install g++</code>
::<code>sudo apt-get install zlib1g-dev</code>
::<code>sudo apt-get install wget</code>
::<code>sudo apt-get install unzip</code>
::<code>sudo apt-get install make</code>
::<code>sudo apt-get install libboost-all-dev</code>
::<code>sudo apt-get install git</code>
<li>Get the CloakCoin source:</li>
::<code>git clone https://github.com/CloakProject/CloakCoin</code>
This will clone the CloakCoin Project source to your machine. If you are in your home directory (by default /home/pi) it will  clone to: /home/pi/CloakCoin
<li>Get and compile libevent</li>
::<code>sudo wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz</code>
::<code>tar -zxf libevent-2.0.21-stable.tar.gz</code>
::<code>cd libevent-2.0.21-stable</code>
::<code>./configure</code>
::<code>make</code>
::<code>sudo make install</code>
<li>Get and compile libssl from source</li>
::<code>wget https://www.openssl.org/source/openssl-1.0.2k.tar.gz</code>
::<code>tar -zxf openssl-1.0.2k.tar.gz</code>
::<code>cd openssl-1.0.2k</code>
::<code>./config</code>
::<code>make</code>
::<code>sudo make install_sw</code> (no docs/manpages)
::<code>echo libssl-dev hold | sudo dpkg --set-selections</code> (keeps from updating)
<li>Get and compile Berkeley db 4.8</li>
::<code>wget http://ftpmirror.your.org/pub/misc/Berkeley-DB/db-4.8.30.zip</code>
::<code>unzip db-4.8.30.zip</code>
::<code>cd db-4.8.30/build_unix</code>
::<code> ../dist/configure --build=aarch64-unknown-linux-gnu --enable-cxx</code>
::<code>make</code>
::<code>sudo make install</code>
<li>Compile levedb</li>
::<code>cd /home/pi/CloakCoin/src/leveldb</code>
::<code>chmod 755 build_detect_platform</code>
::<code>make clean</code>
::<code>make</code> (ignore compile error, the *.a files have already been created)
::<code>cp out-static/*.a .</code>
<li>Get and compile miniupnpc 1.9</li>
::<code>wget http://miniupnp.tuxfamily.org/files/download.php?file=miniupnpc-1.9.20160209.tar.gz</code>
::<code>tar -zxf miniupnpc-1.9.20160209.tar.gz</code>
::<code>cd miniupnpc-1.9.20160209</code>
::<code>make</code>
copy libminiupnpc.a to (cloaksource)/src/miniupnpc with:
::<code>cp libminupnpc.a  /home/pi/CloakCoin/src/miniupnpc</code>
</ol>




==  Compile the wallet ==


<ol>
<li>Change to CloakCoin source directory and compile:</li>
::<code>cd /home/pi/CloakCoin/src</code>
::<code>export CXXFLAG=" -DBOOST_NO_CXX11_SCOPED_ENUMS"</code>
::<code>make -f makefile.unix</code>
You should end up with cloakcoind in /home/pi/CloakCoin/src (grab a cup of coffee, it will take over an hour to complete). On completion do:
::<code>cp ./cloakcoind /usr/local/bin</code>
</ol>




==  Inicialization, Testing and First Commands==


<ol>
<li>Before you start the wallet you need to open a text editor and create CloakCoin's rpc configuraion file with:</li>
::<code>nano /home/pi/.CloakCoin/CloakCoin.conf</code>
<li>Write the following info:</li>
::<code>rpcuser=bitcoinrpc</code>
::<code>rpcpassword= <type some ramdom password that you dont need to remember></code>
press '''Ctrl + O''' then '''Enter''' to save then '''Ctrl + X''' to exit the text editor.
<li>Set it to owner-readable-only with:</li>
::<code>chmod 400 /home/pi/.CloakCoin/CloakCoin.conf</code>
(If you fail to create the above CloakCoin.conf  file,  when starting the wallet with the command cloakcoind you will receive the following ''''error: you must set rpcpassword=<password> in the configuration file: ...'''')
<br>
<li>To start the wallet with the database cache limited to 100Mb type:</li>
::<code>cloakcoind -dbcache=100</code>
<li>Open another console by pressing '''Alt + F2''' and type:</li>
::<code>cloakcoind getinfo</code>
if you get the response:
'''error: couldnt connect to server'''
Wait a few minutes and try again, as soon as you get a response your CloakCoin Pi wallet is up and running, and its a matter of waiting for the connections to come up and the syncing to start.
<li>Sinchronizing with the blockchain can take several days, its faster if you download the blockchain data manually:</li>
::<code>cd /home/pi/.CloakCoin</code>
::<code>wget https://backend.cloakcoin.com/wallet/v2/cloak_ldb.zip</code>
::<code>unzip cloak_ldb.zip</code>
::<code>rm cloak_ldb.zip</code>
<li>Reboot:</li>
::<code>sudo reboot</code>
<li>Start wallet again:</li>
::<code>cloakcoind -dbcache=100</code>
<li>To get  the full list of rpc commands type:</li>
::<code>cloakcoind help</code>
</ol>



==  Backup SD card image ==


It's sensible to keep a copy of the entire SD card image, so you can restore the card if you lose it or it becomes corrupt.

Of course make sure your wallet is encrypted, before making the backup.
<ol>
<li>Para criar um arquivo de imagem de backup no seu computador:</li>
::<code>sudo dd bs=4M if=/dev/sdb of=cloakpi.img</code>
<li> Para restaurar o arquivo de imagem para outro cartão SD, faça:</li>
::<code>sudo dd bs=4M if=cloakpi.img of=/dev/sdb</code>
</ol>


É isso aí, divirta-se!
