Starting all nodes at once on a remote machine from the command line
--------------------------------------------------------------------
By default, ``Cordform`` expects the nodes it generates to be run on the same machine where they were generated.
In order to run the nodes remotely, the nodes can be deployed locally and then copied to a remote server.
If after copying the nodes to the remote machine you encounter errors related to ``localhost`` resolution, you will additionally need to follow the steps below.
To create nodes locally and run on a remote machine perform the following steps:
1. Configure Cordform task and deploy the nodes locally as described in :doc:`generating-a-node`.
2. Copy the generated directory structure to a remote machine using e.g. Secure Copy.
3. Optionally, bootstrap the network on the remote machine.
This is optional step when a remote machine doesn't accept ``localhost`` addresses, or the generated nodes are configured to run on another host's IP address.
If required change host addresses in top level configuration files ``[NODE NAME]_node.conf`` for entries ``p2pAddress`` , ``rpcSettings.address`` and ``rpcSettings.adminAddress``.
Run the network bootstrapper tool to regenerate the nodes network map (see for more explanation :doc:`network-bootstrapper`):
``java -jar corda-tools-network-bootstrapper-Master.jar --dir <nodes-root-dir>``
4. Run nodes on the remote machine using :ref:`runnodes command <starting-all-nodes-at-once>`.
The above steps create a test deployment as ``deployNodes`` Gradle task would do on a local machine.
