# Build and Run Ethereum on CentOS using Terminal.com
# For geth 1.0.0 "frontier", relevant around late July, 2015
#
# These instructions are for building geth and dependencies from scratch
# (should the normal ways of getting it going fail you)
#
# The following are installed:
# - go
# - python
# - python-pip
# - bitcoin
# - mk_genesis_block.py
# - go-ethereum
#
#
# IMPORTANT NOTE: this is documentation and each command should be run by hand

echo "This is documentation; try running the commands one at a time in your terminal."
exit 0

# Step 1: Set Up Terminal
# ------------------------------------------------------------------------------

# - SEE: https://terminal.com/

# Create an account on terminal.com if you don't have one
# Go to "Public Snaps"
# on "Official CentOS 6" click "Try It"
# all commands from now on to be run in your terminal

# your ethereum workspace will be /opt

mkdir -p /opt
cd /opt


# Step 2: Install Ethereum
# ------------------------------------------------------------------------------

# install: go

# - install go dependencies

yum install gcc

# - SEE: https://golang.org/doc/install

cd /opt
wget https://storage.googleapis.com/golang/go1.4.2.linux-amd64.tar.gz

tar -zxvf go1.4.2.linux-amd64.tar.gz
ls go

cd go/src
./all.bash

# - add the following to your ~/.bashrc:
export GOROOT=/opt/go
export PATH=$PATH:$GOROOT/bin

# - load go into your path (it will be there every time you log in as well)
source ~/.bashrc
echo $GOROOT
go

# next install: go-ethereum

# - SEE: https://github.com/ethereum/go-ethereum
# - SEE: https://github.com/ethereum/go-ethereum/wiki/Installation-Instructions-for-Ubuntu

# - install go-ethereum dependencies

yum install gmp-devel
yum install git

# - download and make go-ethereum

cd /opt

git clone https://github.com/ethereum/go-ethereum
cd go-ethereum
make geth


# Step 3: Set Up Genesis Block
# ------------------------------------------------------------------------------

# NOTE: genesis-block seems to be having issues with the version of python in this centos

cd /opt

# first install: the latest python

python --version
yum --showduplicates list python | expand

# - will have to build a newer python

# - install important dependencies for python (later used in building pip)

yum install zlib-devel
yum install openssl-dev

mkdir python

wget https://www.python.org/ftp/python/2.7.10/Python-2.7.10.tgz
tar -zxvf Python-2.7.10.tgz
cd Python-2.7.10
./configure
make
# make test
make altinstall prefix=/opt/python exec-prefix=/opt/python

/opt/python/bin/python2.7 --version
# should now be 2.7.10


# next install: python pip

# NOTE: this is python's package manager

wget https://bootstrap.pypa.io/get-pip.py
/opt/python/bin/python2.7 ./get-pip.py

# next install: bitcoin

/opt/python/bin/pip install bitcoin


# finally install: genesis-block

# SEE: https://blog.ethereum.org/2015/07/27/final-steps/

cd /opt
mkdir genesis-block
cd genesis-block

wget https://raw.githubusercontent.com/ethereum/genesis_block_generator/master/mk_genesis_block.py
/opt/python/bin/python2.7 mk_genesis_block.py > genesis_block.json
ls genesis_block.json


# Step 4: Run Ethereum
# ------------------------------------------------------------------------------

cd /opt

# run: geth w/ the genesis block

cd go-ethereum

./build/bin/geth --genesis ../genesis-block/genesis_block.json console

# geth should be running now
# SEE: https://github.com/ethereum/go-ethereum/wiki/JavaScript-Console
# SCROLL DOWN TO: https://github.com/ethereum/go-ethereum/wiki/JavaScript-Console#personal

# some commands to try:
# > admin.nodeInfo
# > admin.peers
# > admin.chainSyncStatus
# > personal.listAccounts


# run the server w/o console: 
# ./build/bin/geth --genesis ../genesis-block/genesis_block.json
