## Update scripts on validator nodes
|
||
|
|
|
||
|
|
**ONLY FOR VALIDATOR NODES**
|
||
|
|
|
||
|
|
0. this guide assumes that you're running this playbook from the same machine you used to make initial deployment of your node. So that you already have `python` and `ansible` installed, and you have the correct ssh keypair to root-access the node.
|
||
|
|
|
||
|
|
1. clone this repository if you haven't done so before
|
||
|
|
```
|
||
|
|
git clone https://github.com/poanetwork/poa-devops.git
|
||
|
|
cd poa-devops
|
||
|
|
```
|
||
|
|
or pull the latest changes
|
||
|
|
```
|
||
|
|
cd poa-devops
|
||
|
|
git pull origin master
|
||
|
|
```
|
||
|
|
|
||
|
|
2. create/edit `hosts` file:
|
||
|
|
```
|
||
|
|
echo "" > hosts
|
||
|
|
```
|
||
|
|
and put your node's ip address (assuming it's 192.0.2.1) there with the following header:
|
||
|
|
```
|
||
|
|
[set-min-gas-price]
|
||
|
|
192.0.2.1
|
||
|
|
```
|
||
|
|
**NOTE**: if you're updating an existing file, make sure you remove other tags `[...]` and ips.
|
||
|
|
|
||
|
|
4. run the playbook:
|
||
|
|
```
|
||
|
|
ansible-playbook -i hosts set-min-gas-price.yml
|
||
|
|
```
|
||
|
|
|
||
|
|
5. connect to the node
|
||
|
|
```
|
||
|
|
ssh root@192.0.2.1
|
||
|
|
```
|
||
|
|
switch to the home folder:
|
||
|
|
```
|
||
|
|
cd /home/validator
|
||
|
|
```
|
||
|
|
and check the update time of `node.toml` file (should be about the time you started the playbook)
|
||
|
|
```
|
||
|
|
ls -lh
|
||
|
|
# a long list should appear here, look for node.toml in the rightmost column and check the date and time on the same row
|
||
|
|
```
|
||
|
|
then check that line was actually added to the file:
|
||
|
|
```
|
||
|
|
grep min_gas_price node.toml
|
||
|
|
```
|
||
|
|
should return a **single** line:
|
||
|
|
```
|
||
|
|
min_gas_price = 1000000000
|
||
|
|
```
|
||
|
|
also check that backup was created:
|
||
|
|
```
|
||
|
|
ls -lh backups-node.toml/
|
||
|
|
# look for a file named similar to node.toml-20180202-184912 Numbers represent date and time in UTC when the playbook was started
|
||
|
|
```
