# NEO-GO consensus node
|
|
|
|
Neo-go node can act as a consensus node.
|
|
It uses pure Go dBFT implementation from [nspcc-dev/dbft](https://github.com/nspcc-dev/dbft).
|
|
|
|
## How to start your own privnet with neo-go nodes
|
|
### Using existing Dockerfile
|
|
|
|
neo-go comes with two preconfigured private network setups, the first one has
|
|
four consensus nodes and the second one uses single node. Nodes are packed
|
|
into Docker containers and four-node setup shares a volume for chain data.
|
|
|
|
Four-node setup uses ports 20333-20336 for P2P communication and ports
|
|
30333-30336 for RPC (Prometheus monitoring is also available at ports
|
|
20001-20004). Single-node is on ports 20333/30333/20001 for
|
|
P2P/RPC/Prometheus.
|
|
|
|
NeoGo default privnet configuration is made to work with four node consensus,
|
|
you have to modify it if you're to use single consensus node.
|
|
|
|
Node wallets are located in the `.docker/wallets` directory where
|
|
`wallet1_solo.json` is used for single-node setup and all the other ones for
|
|
four-node setup.
|
|
|
|
#### Prerequisites
|
|
- `docker`
|
|
- `docker-compose`
|
|
- `go` compiler
|
|
|
|
#### Instructions
|
|
You can use existing docker-compose file located in `.docker/docker-compose.yml`:
|
|
```bash
|
|
make env_image # build image
|
|
make env_up # start containers, use "make env_single" for single CN
|
|
```
|
|
To monitor logs:
|
|
```bash
|
|
docker-compose -f .docker/docker-compose.yml logs -f
|
|
```
|
|
|
|
To stop:
|
|
```bash
|
|
make env_down
|
|
```
|
|
|
|
To remove old blockchain state:
|
|
```bash
|
|
make env_clean
|
|
```
|
|
|
|
### Start nodes manually
|
|
1. Create a separate config directory for every node and
|
|
place corresponding config named `protocol.privnet.yml` there.
|
|
|
|
2. Edit configuration file for every node.
|
|
Examples can be found at `config/protocol.privnet.docker.one.yml` (`two`, `three` etc.).
|
|
1. Add `UnlockWallet` section with `Path` and `Password` strings for NEP-6
|
|
wallet path and password for the account to be used for consensus node.
|
|
2. Make sure that your `MinPeers` setting is equal to
|
|
the number of nodes participating in consensus.
|
|
This requirement is needed for nodes to correctly
|
|
start and can be weakened in future.
|
|
3. Set you `Address`, `Port` and `RPC.Port` to the appropriate values.
|
|
They must differ between nodes.
|
|
4. If you start binary from the same directory, you will probably want to change
|
|
`DataDirectoryPath` from the `LevelDBOptions`.
|
|
|
|
3. Start all nodes with `neo-go node --config-path <dir-from-step-2>`.
