Deploy a Testnet
|
|
================
|
|
|
|
Now that we've seen how ABCI works, and even played with a few
|
|
applications on a single validator node, it's time to deploy a test
|
|
network to four validator nodes. For this deployment, we'll use the
|
|
``basecoin`` application.
|
|
|
|
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``, and a list of the public
|
|
keys of all validators, stored as ``genesis.json``. These files should
|
|
be stored in ``~/.tendermint``, or wherever the ``$TMROOT`` 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 for each validator using
|
|
``tendermint gen_validator``
|
|
4) Compile a list of public keys for each validator into a
|
|
``genesis.json`` file.
|
|
5) Run ``tendermint node --p2p.seeds=< seed addresses >`` on each node,
|
|
where ``< seed addresses >`` is a comma separated list of the IP:PORT
|
|
combination for each node. The default port for Tendermint is
|
|
``46656``. Thus, if the IP addresses of your nodes were
|
|
``192.168.0.1, 192.168.0.2, 192.168.0.3, 192.168.0.4``, the command
|
|
would look like:
|
|
``tendermint node --p2p.seeds=192.168.0.1:46656,192.168.0.2:46656,192.168.0.3:46656,192.168.0.4:46656``.
|
|
|
|
After a few seconds, all the nodes should connect to eachother and start
|
|
making blocks! For more information, see the Tendermint Networks section
|
|
of `the guide to using Tendermint <using-tendermint.html>`__.

Automated Deployments
|
|
---------------------
|
|
|
|
While the manual deployment is easy enough, an automated deployment is
|
|
usually quicker. The below examples show different tools that can be used
|
|
for automated deployments.
|
|
|
|
Automated Deployment using Kubernetes
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The `mintnet-kubernetes tool <https://github.com/tendermint/tools/tree/master/mintnet-kubernetes>`__
|
|
allows automating the deployment of a Tendermint network on an already
|
|
provisioned kubernetes cluster. For simple provisioning of a kubernetes
|
|
cluster, check out the `Google Cloud Platform <https://cloud.google.com/>`__.
|
|
|
|
Automated Deployment using Terraform and Ansible
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The `terraform-digitalocean tool <https://github.com/tendermint/tools/tree/master/terraform-digitalocean>`__
|
|
allows creating a set of servers on the DigitalOcean cloud.
|
|
|
|
The `ansible playbooks <https://github.com/tendermint/tools/tree/master/ansible>`__
|
|
allow creating and managing a ``basecoin`` or ``ethermint`` testnet on provisioned servers.
|
|
|
|
Package Deployment on Linux for developers
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The ``tendermint`` and ``basecoin`` applications can be installed from RPM or DEB packages on
|
|
Linux machines for development purposes. The packages are configured to be validators on the
|
|
one-node network that the machine represents. The services are not started after installation,
|
|
this way giving an opportunity to reconfigure the applications before starting.
|
|
|
|
The Ansible playbooks in the previous section use this repository to install ``basecoin``.
|
|
After installation, additional steps are executed to make sure that the multi-node testnet has
|
|
the right configuration before start.

Install from the CentOS/RedHat repository:
|
|
|
|
::
|
|
|
|
rpm --import https://tendermint-packages.interblock.io/centos/7/os/x86_64/RPM-GPG-KEY-Tendermint
|
|
wget -O /etc/yum.repos.d/tendermint.repo https://tendermint-packages.interblock.io/centos/7/os/x86_64/tendermint.repo
|
|
yum install basecoin
|
|
|
|
Install from the Debian/Ubuntu repository:
|
|
|
|
::
|
|
|
|
wget -O - https://tendermint-packages.interblock.io/centos/7/os/x86_64/RPM-GPG-KEY-Tendermint | apt-key add -
|
|
wget -O /etc/apt/sources.list.d/tendermint.list https://tendermint-packages.interblock.io/debian/tendermint.list
|
|
apt-get update && apt-get install basecoin
