   • update the url ip addresses of orderer, peer2, orgca, tlsca (4 places).
   • update it with your prime manager's ip address

4. Retrieve hyperledger fabric tls certificates of 'orderer' and 'peer2'

   (Replace ip address with your fabric prime manager's ip address)

   • scp -r root@178.62.207.235:/root/hlft-store/orderer/tls-msp/tlscacerts/tls-tlsca-7054.pem ./hlft-store/orderer/tls-msp/tlscacerts/tls-tlsca-7054.pem

   • scp -r root@178.62.207.235:/root/hlft-store/peer2/tls-msp/tlscacerts/tls-tlsca-7054.pem ./hlft-store/peer2/tls-msp/tlscacerts/tls-tlsca-7054.pem

5. Enroll admin

   • Command : node enrollAdmin.js

   • check wallet directory
     • a directory named 'admin' will be available
       • certificates for admin will be available under this directory.

6. Register user

   • If needed, edit the following lines in registerUser.js
     • const user_name = "lion";
     • const user_password = "lion";

       • certificates for the registerd user will be available under this directory.

7. Query a chaincode

   • If needed, edit the following lines in query.js
     • const user_name = "lion";
     • const CHANNEL_NAME = "appchannel";
     • const CHAIN_CODE_NAME = "carcc";
     • const CHAIN_CODE_FUNCTION_NAME = "listCars";
     • const result = await contract.evaluateTransaction(CHAIN_CODE_FUNCTION_NAME);
     • const result = await contract.evaluateTransaction(CHAIN_CODE_FUNCTION_NAME,"b");

   • Command : node query.js

8. Invoke a chaincode

   • If needed, edit the following lines in invoke.js
     • const user_name = "lion";
     • const CHANNEL_NAME = "appchannel";
     • const CHAIN_CODE_NAME = "carcc";
     • const CHAIN_CODE_FUNCTION_NAME = "createCar";
     • await contract.submitTransaction(CHAIN_CODE_FUNCTION_NAME, "TR8800","Opel","Corsa","Light Blue","7","2050","1");
     • await contract.submitTransaction(CHAIN_CODE_FUNCTION_NAME, "b","a","1");

   • Command : node invoke.js
