Playbooks for setting up geth nodes for main net and Ropsten

Install

Clone the role into your geth configuration.

git clone https://github.com/mikeshultz/ansible-geth.git /etc/ansible/roles/geth

Create a role for your machine that inherits from this one to change the default options.

---
- hosts: ropsten
  become: yes
  become_method: sudo
  vars:
    geth_testnet: true
    geth_cache: 512
    geth_port: 30304
    geth_datadir: /data/ropsten
    geth_rpc: true
    geth_rpcpublic: true
    geth_rpcaddr: 0.0.0.0
    geth_rpcport: 8080
    geth_rpcapi: "eth,net,web3"
    geth_rpccorsdomain: "*"
  roles:
    - geth

Configure

Add machines to the role geth for main net, or geth_ropsten for ropsten. You can have nodes in both roles.

Etherbase Account

mainnet_etherbase_password and/or ropsten_etherbase_password should be specified in your vars. This is the default password for your etherbase account. This seems to be required for RPC calls. So if you plan on using RPC, even if it's a read-only node, you should do this. You can leave this var undefined and manually setup accounts yourself after deploy as well.
