Deploying a node
|
|
================
|
|
|
|
.. contents::
|
|
|
|
.. note:: These instructions are intended for people who want to deploy a Corda node to a server,
|
|
whether they have developed and tested a CorDapp following the instructions in :doc:`generating-a-node`
|
|
or are deploying a third-party CorDapp.
|
|
|
|
Linux: Installing and running Corda as a system service
|
|
-------------------------------------------------------
|
|
We recommend creating system services to run a node and the optional webserver. This provides logging and service
|
|
handling, and ensures the Corda service is run at boot.
|
|
|
|
**Prerequisites**:
|
|
|
|
* Oracle Java 8. The supported versions are listed in :doc:`getting-set-up`
|
|
|
|
1. Add a system user which will be used to run Corda:
|
|
|
|
``sudo adduser --system --no-create-home --group corda``
|
|
|
|
2. Create a directory called ``/opt/corda`` and change its ownership to the user you want to use to run Corda:
|
|
|
|
``mkdir /opt/corda; chown corda:corda /opt/corda``
|
|
|
|
3. Download the `Corda jar <https://r3.bintray.com/corda/net/corda/corda/>`_
|
|
(under ``/VERSION_NUMBER/corda-VERSION_NUMBER.jar``) and place it in ``/opt/corda``
|
|
|
|
4. (Optional) Download the `Corda webserver jar <http://r3.bintray.com/corda/net/corda/corda-webserver/>`_
|
|
(under ``/VERSION_NUMBER/corda-VERSION_NUMBER.jar``) and place it in ``/opt/corda``
|
|
|
|
5. Create a directory called ``cordapps`` in ``/opt/corda`` and save your CorDapp jar file to it. Alternatively, download one of
|
|
our `sample CorDapps <https://www.corda.net/samples/>`_ to the ``cordapps`` directory
|
|
|
|
6. Save the below as ``/opt/corda/node.conf``. See :doc:`corda-configuration-file` for a description of these options
|
|
|
|
.. code-block:: json
|
|
|
|
basedir : "/opt/corda"
|
|
p2pAddress : "example.com:10002"
|
|
rpcAddress : "example.com:10003"
|
|
webAddress : "0.0.0.0:10004"
|
|
h2port : 11000
|
|
emailAddress : "you@example.com"
|
|
myLegalName : "O=Bank of Breakfast Tea, L=London, C=GB"
|
|
keyStorePassword : "cordacadevpass"
|
|
trustStorePassword : "trustpass"
|
|
devMode : false
|
|
rpcUsers=[
|
|
{
|
|
user=corda
|
|
password=portal_password
|
|
permissions=[
|
|
ALL
|
|
]
|
|
}
|
|
]
|
|
|
|
7. Make the following changes to ``/opt/corda/node.conf``:
|
|
|
|
* Change the ``p2pAddress`` and ``rpcAddress`` values to start with your server's hostname or external IP address.
|
|
This is the address other nodes or RPC interfaces will use to communicate with your node
|
|
* Change the ports if necessary, for example if you are running multiple nodes on one server (see below)
|
|
* Enter an email address which will be used as an administrative contact during the registration process. This is
|
|
only visible to the permissioning service
|
|
* Enter your node's desired legal name. This will be used during the issuance of your certificate and should rarely
|
|
change as it should represent the legal identity of your node
|
|
|
|
* Organization (``O=``) should be a unique and meaningful identifier (e.g. Bank of Breakfast Tea)
|
|
* Location (``L=``) is your nearest city
|
|
* Country (``C=``) is the `ISO 3166-1 alpha-2 code <https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2>`_
|
|
* Change the RPC username and password
|
|
|
|
.. note:: Ubuntu 16.04 and most current Linux distributions use SystemD, so if you are running one of these
|
|
distributions follow the steps marked **SystemD**.
|
|
If you are running Ubuntu 14.04, follow the instructions for **Upstart**.
|
|
|
|
8. **SystemD**: Create a ``corda.service`` file based on the example below and save it in the ``/etc/systemd/system/``
|
|
directory
|
|
|
|
.. code-block:: shell
|
|
|
|
[Unit]
|
|
Description=Corda Node - Bank of Breakfast Tea
|
|
Requires=network.target
|
|
|
|
[Service]
|
|
Type=simple
|
|
User=corda
|
|
WorkingDirectory=/opt/corda
|
|
ExecStart=/usr/bin/java -Xmx2048m -jar /opt/corda/corda.jar
|
|
Restart=on-failure
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
|
|
8. **Upstart**: Create a ``corda.conf`` file based on the example below and save it in the ``/etc/init/`` directory
|
|
|
|
.. code-block:: shell
|
|
|
|
description "Corda Node - Bank of Breakfast Tea"
|
|
|
|
start on runlevel [2345]
|
|
stop on runlevel [!2345]
|
|
|
|
respawn
|
|
setuid corda
|
|
chdir /opt/corda
|
|
exec java -Xmx2048m -jar /opt/corda/corda.jar
|
|
|
|
9. Make the following changes to ``corda.service`` or ``corda.conf``:
|
|
|
|
* Make sure the service description is informative - particularly if you plan to run multiple nodes.
|
|
* Change the username to the user account you want to use to run Corda. **We recommend that this user account is
|
|
not root**
|
|
* Set the maximum amount of memory available to the Corda process by changing the ``-Xmx2048m`` parameter
|
|
* **SystemD**: Make sure the ``corda.service`` file is owned by root with the correct permissions:
|
|
|
|
* ``sudo chown root:root /etc/systemd/system/corda.service``
|
|
* ``sudo chmod 644 /etc/systemd/system/corda.service``
|
|
|
|
* **Upstart**: Make sure the ``corda.conf`` file is owned by root with the correct permissions:
|
|
|
|
* ``sudo chown root:root /etc/init/corda.conf``
|
|
* ``sudo chmod 644 /etc/init/corda.conf``
|
|
|
|
.. note:: The Corda webserver provides a simple interface for interacting with your installed CorDapps in a browser.
|
|
Running the webserver is optional.
|
|
|
|
10. **SystemD**: Create a ``corda-webserver.service`` file based on the example below and save it in the ``/etc/systemd/system/``
|
|
directory
|
|
|
|
.. code-block:: shell
|
|
|
|
[Unit]
|
|
Description=Webserver for Corda Node - Bank of Breakfast Tea
|
|
Requires=network.target
|
|
|
|
[Service]
|
|
Type=simple
|
|
User=corda
|
|
WorkingDirectory=/opt/corda
|
|
ExecStart=/usr/bin/java -jar /opt/corda/corda-webserver.jar
|
|
Restart=on-failure
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
|
|
10. **Upstart**: Create a ``corda-webserver.conf`` file based on the example below and save it in the ``/etc/init/``
|
|
directory
|
|
|
|
.. code-block:: shell
|
|
|
|
description "Webserver for Corda Node - Bank of Breakfast Tea"
|
|
|
|
start on runlevel [2345]
|
|
stop on runlevel [!2345]
|
|
|
|
respawn
|
|
setuid corda
|
|
chdir /opt/corda
|
|
exec java -jar /opt/corda/corda-webserver.jar
|
|
|
|
11. Provision the required certificates to your node. Contact the network permissioning service or see
|
|
:doc:`permissioning`
|
|
|
|
12. **SystemD**: You can now start a node and its webserver and set the services to start on boot by running the
|
|
following ``systemctl`` commands:
|
|
|
|
* ``sudo systemctl daemon-reload``
|
|
* ``sudo systemctl enable --now corda``
|
|
* ``sudo systemctl enable --now corda-webserver``
|
|
|
|
12. **Upstart**: You can now start a node and its webserver by running the following commands:
|
|
|
|
* ``sudo start corda``
|
|
* ``sudo start corda-webserver``
|
|
|
|
The Upstart configuration files created above tell Upstart to start the Corda services on boot so there is no need to explicitly enable them.
|
|
|
|
You can run multiple nodes by creating multiple directories and Corda services, modifying the ``node.conf`` and
|
|
SystemD or Upstart configuration files so they are unique.
|
|
|
|
Windows: Installing and running Corda as a Windows service
|
|
----------------------------------------------------------
|
|
We recommend running Corda as a Windows service. This provides service handling, ensures the Corda service is run
|
|
at boot, and means the Corda service stays running with no users connected to the server.
|
|
|
|
**Prerequisites**:
|
|
|
|
* Oracle Java 8. The supported versions are listed in :doc:`getting-set-up`
|
|
|
|
1. Create a Corda directory and download the Corda jar. Replace ``VERSION_NUMBER`` with the desired version. Here's an
|
|
example using PowerShell:
|
|
|
|
.. code-block:: PowerShell
|
|
|
|
mkdir C:\Corda
|
|
wget http://jcenter.bintray.com/net/corda/corda/VERSION_NUMBER/corda-VERSION_NUMBER.jar -OutFile C:\Corda\corda.jar
|
|
|
|
2. Create a directory called ``cordapps`` in ``C:\Corda\`` and save your CorDapp jar file to it. Alternatively,
|
|
download one of our `sample CorDapps <https://www.corda.net/samples/>`_ to the ``cordapps`` directory
|
|
|
|
3. Save the below as ``C:\Corda\node.conf``. See :doc:`corda-configuration-file` for a description of these options
|
|
|
|
.. code-block:: json
|
|
|
|
basedir : "C:\\Corda"
|
|
p2pAddress : "example.com:10002"
|
|
rpcAddress : "example.com:10003"
|
|
webAddress : "0.0.0.0:10004"
|
|
h2port : 11000
|
|
emailAddress: "you@example.com"
|
|
myLegalName : "O=Bank of Breakfast Tea, L=London, C=GB"
|
|
keyStorePassword : "cordacadevpass"
|
|
trustStorePassword : "trustpass"
|
|
extraAdvertisedServiceIds: [ "" ]
|
|
devMode : false
|
|
rpcUsers=[
|
|
{
|
|
user=corda
|
|
password=portal_password
|
|
permissions=[
|
|
ALL
|
|
]
|
|
}
|
|
]
|
|
|
|
4. Make the following changes to ``C:\Corda\node.conf``:
|
|
|
|
* Change the ``p2pAddress`` and ``rpcAddress`` values to start with your server's hostname or external IP address.
|
|
This is the address other nodes or RPC interfaces will use to communicate with your node
|
|
* Change the ports if necessary, for example if you are running multiple nodes on one server (see below)
|
|
* Enter an email address which will be used as an administrative contact during the registration process. This is
|
|
only visible to the permissioning service
|
|
* Enter your node's desired legal name. This will be used during the issuance of your certificate and should rarely
|
|
change as it should represent the legal identity of your node
|
|
|
|
* Organization (``O=``) should be a unique and meaningful identifier (e.g. Bank of Breakfast Tea)
|
|
* Location (``L=``) is your nearest city
|
|
* Country (``C=``) is the `ISO 3166-1 alpha-2 code <https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2>`_
|
|
* Change the RPC username and password
|
|
|
|
5. Copy the required Java keystores to the node. See :doc:`permissioning`
|
|
|
|
6. Download the `NSSM service manager <nssm.cc>`_
|
|
|
|
7. Unzip ``nssm-2.24\win64\nssm.exe`` to ``C:\Corda``
|
|
|
|
8. Save the following as ``C:\Corda\nssm.bat``:
|
|
|
|
.. code-block:: batch
|
|
|
|
nssm install cordanode1 C:\ProgramData\Oracle\Java\javapath\java.exe
|
|
nssm set cordanode1 AppDirectory C:\Corda
|
|
nssm set cordanode1 AppParameters "-Xmx2048m -jar corda.jar --config-file=C:\corda\node.conf"
|
|
nssm set cordanode1 AppStdout C:\Corda\service.log
|
|
nssm set cordanode1 AppStderr C:\Corda\service.log
|
|
nssm set cordanode1 Description Corda Node - Bank of Breakfast Tea
|
|
nssm set cordanode1 Start SERVICE_AUTO_START
|
|
sc start cordanode1
|
|
|
|
9. Modify the batch file:
|
|
|
|
* If you are installing multiple nodes, use a different service name (``cordanode1``) for each node
|
|
* Set the amount of Java heap memory available to this node by modifying the -Xmx argument
|
|
* Set an informative description
|
|
|
|
10. Run the batch file by clicking on it or from a command prompt
|
|
|
|
11. Run ``services.msc`` and verify that a service called ``cordanode1`` is present and running
|
|
|
|
12. Run ``netstat -ano`` and check for the ports you configured in ``node.conf``
|
|
|
|
13. You may need to open the ports on the Windows firewall
|
|
|
|
Testing your installation
|
|
-------------------------
|
|
You can verify Corda is running by connecting to your RPC port from another host, e.g.:
|
|
|
|
``telnet your-hostname.example.com 10002``
|
|
|
|
If you receive the message "Escape character is ^]", Corda is running and accessible. Press Ctrl-] and Ctrl-D to exit
|
|
telnet.
