Setup blockchain backup from a node:

1. connect to the node as root.

2. clone this repository to root's home folder:

git clone https://github.com/poanetwork/poa-devops.git

3. make sure python (v2.6+ or v3.5+) is installed on the node.

4. install pip and/or upgrade it to the newest version:

apt-get install python-pip
pip install --upgrade pip

5. upgrade setuptools to the newest version:

pip install --upgrade setuptools

6. install ansible:

pip install ansible

7. create group_vars/all file:

and set the following variables in it:

• poa_role - node's role (one of bootnode, validator, moc, explorer, netstat)
• access_key - s3 access key
• secret_key - s3 secret key
• s3_bucket - s3 bucket name

8. create hosts file:

cp hosts.example hosts

and set it to run on localhost:

9. run playbook (still, do this on the node)

ansible-playbook -i hosts -c local site.yml

10. if all is well, setup a cronjob to run every hour:

crontab -e
