Hey all,

In this tutorial I am going to walk you through rE-cycling your old pc units and turn them into something new! Today we will be focusing on:

• System Requirements
• Installing Ubuntu
• Router Setup
• Domain Name
• Geth
  
  No, Not that geth!

To get started you will need/SYS REQ:

• 4 GB of RAM
• CPU with at least 2 cores
• 500 GB of storage, Either NAS or onboard

Got all that?! Good let's get started.

The first thing you will want to do is get a copy of Ubuntu.

You will want to burn this image to a disk. Do not attempt to mount it using ISO tools and installing. This is pretty straight forward. While installing you will want your computer connected to your router during this process. Setup will configure your connection settings.

At the end of your setup you should see a screen that will prompt you to name it. **Name it what you wish, however you will need to write down what your naming it, we will go more into that later.)

Router Setup

Log into your router. You will want to setup port forwarding, so navigate to port forwarding.
Once inside port forwarding you will want a table try to replicate your table with this one:

Protocol	Port	TCP/UDP	IP Address
HTTP	80 80	TCP	Server IP
FTP	21 21	TCP/UDP	Server IP
SSH	22 22	TCP	Server IP
will use for ember	8082	TCP/UDP	Server IP

Obviously, save settings...

Domain Name

You can get a domain name by using your server IP address, this is a free and simple website. http://www.no-ip.com

Test it, Enter the domain name into your browser. If it works! Success!! If not, try your server's IP address. If that doesn't work, then recheck your port forwarding.

Ok so after all this you will want to login as root. Next we will want to check for Ubuntu updates.
apt-get update
apt-get dist-upgrade

Setup SWAP

dd if=/dev/zero
of=/mnt/myswap.swap bs=1M

count=4000
mkswap /mnt/myswap.swap
swapon /mnt/myswap.swap

To make your server start at boot (recommended), we will want to enable fstab.
nano/etc/fstab
Now at the end of the file add this:
/mnt/myswap.swap none sw 0 0
Now save and exit (Ctrl+O and Ctrl+X)

Installing Required Packages

apt-get install git
apt-get install build-essential libtool
autotools-dev autoconf pkg-config libssl-dev
apt-get install libboost-all-dev git npm
nodejs nodejs-legacy libminiupnpc-dev
redis-server
apt-get update
apt-get install libdb4.8-dev libdb4.8++-dev
apt-get install golang
sudo apt-get update
sudo apt-get install nginx

Wallet Setup

There are two ways of setup, I will cover them both.

We are going to build Golang from source

`` git clone https://github.com/vaporry/go-ethereum``

Clone this to a convient directory for your

sudo apt-get install -y build-essential golang
cd go-ethereum
make geth

Option 2, installing from PPA

sudo apt-get install software-properties-common
sudo add-apt-repository -y
ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install ethereum

After setup has completed run commands to generate a new account. IT is important like always to write your information down and store it in a safe place. (sometimes in plain sight is safest).
geth account new

We are almost completed... now to fill up the pool!

git config --global

http.https://gopkg.in.followRedirects true
git clone https://github.com/sammy007/open-ethereum-pool.git
cd open-ethereum-pool
make

./build/bin/open-ethereum-pool config.json

For the front end we will be using ember.js its a program that polls the pool API to render miner stats.
cd www

You will change the API URL: to match your domain name should be path www/config/enviroment.js, both need to match your domain name.

Installing ember

npm install -g [email protected]
npm install -g bower
npm install 
bower install
./build.sh

API using nginx

upstream api{
server 127.0.0.1:8080;
}

location /api{
proxy_pass http://api;
}

Ember

ember server --port 8082 --enviroment
development

Config

Using the default config file we will edit this to our liking. I would encourage everyone to think before finalizing this, also I will state here to setup the templates for web server production www/app/templates. dont use the built in ones

{
//set number of Cores for server
**"threads":2**

//Prefix for keys in redis store
"coin":"eth"

//Give unique name to each instance "name": "main",
