## Manual Deployments
|
|
|
|
It's relatively easy to setup a Tendermint cluster manually. The only
|
|
requirements for a particular Tendermint node are a private key for the
|
|
validator, stored as `priv_validator.json`, a node key, stored as
|
|
`node_key.json` and a list of the public keys of all validators, stored
|
|
as `genesis.json`. These files should be stored in
|
|
`~/.tendermint/config`, or wherever the `$TMHOME` variable might be set
|
|
to.
|
|
|
|
Here are the steps to setting up a testnet manually:
|
|
|
|
1. Provision nodes on your cloud provider of choice
|
|
2. Install Tendermint and the application of interest on all nodes
|
|
3. Generate a private key and a node key for each validator using
|
|
`tendermint init`
|
|
4. Compile a list of public keys for each validator into a
|
|
new `genesis.json` file and replace the existing file with it.
|
|
5. Get the node IDs of any peers you want other peers to connect to by
|
|
running `tendermint show_node_id` on the relevant machine
|
|
6. Set the `p2p.persistent_peers` in the config for all nodes to the comma
|
|
separated list of `ID@IP:PORT` for all nodes. Default port is 26656.
|
|
|
|
Then start the node
|
|
|
|
```
|
|
tendermint node --proxy_app=kvstore
|
|
```
|
|
|
|
After a few seconds, all the nodes should connect to each other and
|
|
start making blocks! For more information, see the Tendermint Networks
|
|
section of [the guide to using Tendermint](../tendermint-core/using-tendermint.md).
|
|
|
|
But wait! Steps 3, 4 and 5 are quite manual. Instead, use the `tendermint testnet` command. By default, running `tendermint testnet` will create all the
|
|
required files, but it won't populate the list of persistent peers. It will do
|
|
it however if you provide the `--populate-persistent-peers` flag and optional
|
|
`--starting-ip-address` flag. Run `tendermint testnet --help` for more details
|
|
on the available flags.
|
|
|
|
```
|
|
tendermint testnet --populate-persistent-peers --starting-ip-address 192.168.0.1
|
|
```
|
|
|
|
This command will generate four folders, prefixed with "node" and put them into
|
|
the "./mytestnet" directory by default.
|
|
|
|
As you might imagine, this command is useful for manual or automated
|
|
deployments.
|
|
|
|
## Automated Deployments
|
|
|
|
The easiest and fastest way to get a testnet up in less than 5 minutes.
|
|
|
|
### Local
|
|
|
|
With `docker` and `docker-compose` installed, run the command:
|
|
|
|
```
|
|
make localnet-start
|
|
```
|
|
|
|
from the root of the tendermint repository. This will spin up a 4-node
|
|
local testnet. Review the target in the Makefile to debug any problems.
|
|
|
|
### Cloud
|
|
|
|
See the [next section](./terraform-and-ansible.md) for details.
