## 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 `boto` and `boto3` packages:
|
||
|
|
```
|
||
|
|
pip install boto boto3
|
||
|
|
```
|
||
|
|
|
||
|
|
7. install `ansible`:
|
||
|
|
```
|
||
|
|
pip install ansible
|
||
|
|
```
|
||
|
|
|
||
|
|
8. create `group_vars/all` file:
|
||
|
|
```
|
||
|
|
cp group_vars/all.example group_vars/all
|
||
|
|
```
|
||
|
|
and set the following variables:
|
||
|
|
* `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
|
||
|
|
|
||
|
|
you can ignore other variables in this file
|
||
|
|
|
||
|
|
9. create `hosts` file:
|
||
|
|
```
|
||
|
|
touch hosts
|
||
|
|
```
|
||
|
|
and set it to run `backup` on localhost:
|
||
|
|
```
|
||
|
|
[backup]
|
||
|
|
localhost
|
||
|
|
```
|
||
|
|
|
||
|
|
10. run playbook (still, do this on the node)
|
||
|
|
```
|
||
|
|
ansible-playbook -i hosts -c local site.yml
|
||
|
|
```
|
||
|
|
|
||
|
|
11. if all is well, setup a cronjob to run every hour:
|
||
|
|
```
|
||
|
|
crontab -e
|
||
|
|
```
|
||
|
|
append the following line:
|
||
|
|
```
|
||
|
|
30 * * * * /bin/bash /root/poa-devops/bkp-blockchain-cron.sh
|
||
|
|
```
|
||
|
|
|
||
|
|
12. configure logrotate to archive old log files. Create file `/etc/cron.hourly/poa-devops-logrotate` with the following content:
|
||
|
|
```
|
||
|
|
#!/bin/bash
|
||
|
|
/usr/sbin/logrotate /root/poa-devops/bkp-blockchain-logrotate.conf
|
||
|
|
```
|
||
|
|
and set permission to run it:
|
||
|
|
```
|
||
|
|
chmod 755 /etc/cron.hourly/poa-devops-logrotate
|
||
|
|
```
