# Ansible install script for Steem



This is an Ansible playbook that sets up steemd on Ubuntu 14.04 for mining, witness or seeding. An automated playbook saves you a lot of time of manual package building and configuration process.



## Features



* Compatible with any server provider: Amazon, Linode, Digital Ocean, Azure



* Creates processor optimal steemd mining configuration and makes steemd to start on the server reboot



* Starts steemd under screen so you can connect to the session easily to diagnose possible problems



* Generates initial private key with brain key configuration file for mining



### Prerequisites



* Get a server with SSH access



* Make sure you have port 2001 open for incoming TCP/IP connections



* Have Python 2.7 and virtualenv command installed on a local computer in order to run Ansible. [Windows download link](https://www.python.org/download/releases/2.7/). For Linux use your distribution provided Python 2.7 package. For OSX you have Python 2.7 installed out of the box.



* You need to set up [SSH to allow passwordless connection to you server](https://opensourcehacker.com/2012/10/24/ssh-key-and-passwordless-login-basics-for-developers/).



Example for Amazon:



    ssh-add key-file-given-by-amazon.pem



## Installation



Clone yourself a local copy of this repository from Github:



    git clone [email protected]:miohtama/ansible-steem.git



.. or if you do not have Git use [direct download link](https://github.com/miohtama/ansible-steem/archive/master.zip).



## Usage



These instructions walk you through to set up *steemd* in mining mode. For witness or seed node see more instructions below.



Create and activate Python 2.7 venv:



    virtualenv -p python2.7 venv

    source venv/bin/activate



Install Ansible in this virtual environment:



    pip install ansible



Edit `playbook.yml` and add your steem account name:



    # My account name on steemit.com - CHANGE THIS

    steem_account: moo9000



Create a `hosts.ini` file that points to your server(s). In this example we use Amazon EC2 server with ubuntu user having sudo access. `hosts.ini`:



    [default]

    steem ansible_host=78.47.53.101 ansible_user=ubuntu



Here



* **ansible_host** is your server IP address



* **ansible_user** is a UNIX user with sudo access rights



Run Ansible:



    ansible-playbook -i hosts.ini



This will take 30-60 minutes depending on the server.



The miner should be up and running. To confirm this do:



    ssh YOUR SERVER IP ADDRESS

    screen -x



You should see steemd miner pushing out a lot of status text like:



    86718ms th_a       witness.cpp:425               on_applied_block     ] hash rate: 1 hps  target: 29 queue: 102 estimated time to produce: 8947848 minutes

    86719ms th_a       witness.cpp:425               on_applied_block     ] hash rate: 1 hps  target: 29 queue: 102 estimated time to produce: 8947848 minutes



Now detach from the screen using `CTRL + A` and then D`.



Before leaving the server get a backup copy of your private key:



    cat brainkey.json



Print this and store it in a safe location.



# Restart



The following will restart both screen and steemd:



    sudo /home/ubuntu/steem/programs/steemd/restart-miner.bash



# Testing playbook locally using Vagrant



Spin up a virtual machine using Vagrant and playbook locally:



    vagrant up



See its running:



    vagrant ssh

    screen -x
