How to setup a Corda Network using CENM tool (Part 2)

In the previous article we have seen how to setup a corda network using CENM tool. If you haven’t set it up yet then please go through the first part https://raokarthik83.medium.com/how-to-setup-a-corda-network-using-cenm-tool-55282660d2d0

Now we will be adding new nodes to the network. Let’s first look at our existing network structure.

CENM network staging directory

Network map snapshot from notary

I am using enterprise corda-4.8.jar. If you want to use open source version then you can go with it. You can download the open source version here → https://repo1.maven.org/maven2/net/corda/corda/4.8/

So, we will be adding two new nodes to the network —PartyA and PartyB.

Following are the steps required for the node setup:

1. Create new staging directory
2. Place network root trust-store and corda.jar in the staging directory.
3. Create node.conf
4. Run initial registration from the staging directory.
5. Run the node.

Setup PartyA:

1. Create a staging directory for PartyA.

mkdir PartyA
cd PartyA

2. Copy network root trust-store from pki folder to PartyA staging directory. Also place corda.jar in the staging directory. I am using corda-4.8 enterprise jar.

cp ../pki/trust-stores/network-root-truststore.jks .

PartyA staging directory

3. Create node.conf for PartyA

myLegalName="O=PartyA,L=London,C=GB"

networkServices {
  doormanURL="http://localhost:10000"
  networkMapURL="http://localhost:20000"
}

devMode = false

sshd {
  port = 2226
}

p2pAddress="localhost:7000"
rpcUsers=[
  {
    user=testuser
    password=password
    permissions=[
        ALL
    ]
  }
]

rpcSettings {
  address = "localhost:7001"
  adminAddress = "localhost:7002"
}

4. Run initial registration for PartyA

java -jar corda-4.8.jar --initial-registration --network-root-truststore-password trustpass --network-root-truststore network-root-truststore.jks

Initial registration PartyA

5. Run the node

java -jar corda-4.8.jar

Run PartyA Node

Setup PartyB:

1. Create a staging directory for PartyB

mkdir PartyB
cd PartyB

2. Copy network root trust-store and corda.jar to the staging directory.

cp ../pki/trust-stores/network-root-truststore.jks .

3. Create node.conf for PartyB

myLegalName="O=PartyB,L=London,C=GB"

networkServices {
  doormanURL="http://localhost:10000"
  networkMapURL="http://localhost:20000"
}

devMode = false

sshd {
  port = 2225
}

p2pAddress="localhost:8000"
rpcUsers=[
  {
    user=testuser
    password=password
    permissions=[
        ALL
    ]
  }
]

rpcSettings {
  address = "localhost:8001"
  adminAddress = "localhost:8002"
}

4. Run initial registration

java -jar corda-4.8.jar --initial-registration --network-root-truststore-password trustpass --network-root-truststore network-root-truststore.jks

PartyB directory after initial registration

5. Run the node

java -jar corda-4.8.jar

Run PartyB node

Okay so, we have completed the node setup. Let’s confirm the setup by checking the network map snapshot at PartyB.

Login to PartyB crash shell

NOTE: Password is password

ssh -p 2225 localhost -l testuser

Party B Crash shell

This concludes the corda network setup using CENM.

I hope this helps 😄
