GETH LIGHT NODE BOOTSTRAPPER

This project is a quick GO-ETHEREUM NODE INSTALLATION HELPER for ubuntu vps/servers. It's is particularly suitable for deploying a node on a newly installed server from your Lunix/Mac workstation.

AUTO-INSTALL

Make sure you have an ssh key on you local machine Just start bootstrap.sh stript and follow the instructions...

MANUAL PROCEDURE

1 - Deploy on a server

To manualy deploy this helper on a server, first deploy your ssh-key on it (ssh-copy-id root@<Server_IP>) and then just run rsync -av --checksum --exclude ".git" --exclude ".DS_Store" ./* root@<Server_IP>:

2 - Install the new Node

On the remote server, install the dependences:

sudo apt-get -y install software-properties-common
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get -y install ethereum htop fail2ban

And create an ethereum user:

adduser --disabled-password --gecos ethnode
mkdir /home/ethnode/.ssh
cp -fr .ssh/authorized_keys /home/ethnode/.ssh/
chown -R ethnode:ethnode /home/ethnode/.ssh
chmod 700 /home/ethnode/.ssh

Or use the all-in-one script ./install_node.sh

Start the node

Start a mainnet node with following command on a screen

geth --syncmode "light" --rpc --rpcapi db,eth,net,web3,personal \
     --cache=1024  --rpcport 7000 --rpccorsdomain "*" --maxpeers "50" \
     --datadir="/home/ethnode/.ethereum_mainnet"  \
     console 2> /home/ethnode/geth_mainnet.log

Or use the all-in-one script ./start_mainnet.sh

Same procedure for a testnet node :

geth --testnet --syncmode "light" --port 0 --rpc --rpcapi db,eth,net,web3,personal  \
     --cache=1024 --rpcport 7001 --rpccorsdomain "*" --maxpeers "50"  \
     --datadir="/home/ethnode/.ethereum_testnet"  \
     console 2> /home/ethnode/geth_testnet.log

Or use the all-in-one script ./start_testnet.sh

Connect to the geth console

Attach the geth mainnet or testnet screen to your terminal session: screen -x [testnet|mainnet] Or use the all-in-one script ./connect_[testnet|mainnet].sh

Import a Wallet (mainnet or testnet)

To deploy/use write fonctions of your(s) smart contract(s), first import the wallet: personal.importRawKey("<PRIVATE KEY>","<PASSPHRASE>");
