Install

In our second session we installed Geth on Mac/Win/Linux, set up a private local network, and wrote some basic contract code in solidity. The first part for any development is obviously installing the client. To do that, visit https://ethereum.org/cli for the relevant Geth clients and follow the instructions; there are other Ethereum clients available, but for our meetup group we are focusing on Geth.

Ethereum Geth Clients (Linux/Mac/Win)

Although a larger set of instructions are found at https://ethereum.org/cli, let's briefly list the basic install commands here.

To install on linux (Ubuntu) run the follow commands:

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

Mac: Install brew and make sure it's updated.

brew update
brew upgrade

After you have that installed, load Ethereum

brew tap ethereum/ethereum
brew install ethereum

Windows: Download the latest stable binary. Open up a command prompt and cd to that directory, and then run geth.exe
