Open config folder, use only json config files:

  • connection-org1.json
  • connection-org1.yaml
  • connection-org2.json
  • connection-org2.yaml

  1. Import tlsCACerts Certificates into "connection-org1.json":

     "peers": {
     "peer0.org1.example.com": {
         "url": "grpcs://localhost:7051",

  3. Install Package Dependencies and run network:

     npm install

 node app.js

  4. Production Host gateway available:

     sudo nano /etc/hosts

 ex: 192.168.0.0 peer0.org1.example.com

 [blockchain_ip] peer0.org1.example.com
 [blockchain_ip] peer1.org1.example.com
 [blockchain_ip] orderer.example.com
 [blockchain_ip] peer0.org2.example.com
 [blockchain_ip] peer1.org2.example.com
 [blockchain_ip] orderer2.example.com
 [blockchain_ip] orderer3.example.com
 [blockchain_ip] ca.org1.example.com
 [blockchain_ip] ca.org2.example.com
 [blockchain_ip] ca_orderer

  5. Docker: 1 - Install:

    sudo apt-get update 
sudo apt-get upgrade
sudo apt install docker.io
sudo systemctl start docker
sudo systemctl enable docker
sudo systemctl status docker
docker --version

    2 - Switch user:

    sudo usermod -aG docker ${USER}
su - ${USER}
id -nG
sudo usermod -aG docker addusernamehere

    NOTE: if you want to build only one image ther following cmd:

    3 - Build:

    docker build --tag conun-middleware-testnet-v3:0.1 .

    4 - Run Docker image:

    docker run -d -p 4040:4040 -v /home/conun/conun-middleware-testnet-v3/wallet:/conun-middleware-testnet-v3/wallet -it conun-middleware-testnet-v3:0.1

    5 - install editor inside docker:

    apt-get update && apt-get install nano

  6. Docker Compose:

    sudo apt install docker-compose
docker-compose --version
    1. Run Docker Compose
    docker-compose up       or          docker-compose up --build
    1. Stop Docker Compose
    docker-compose down
    1. Stop and Delete Docker Containers
    docker stop $(docker ps -aq) && docker rm $(docker ps -aq)
    1. Delete Docker Images
    docker rmi -f $(docker images -a -q)
    1. Check Decker
    docker ps       or      docker ps -a        or          docker images
    1. If you need to go inside a container exec, you can use a command:
    docker exec -it <container id> /bin/bash

  7. MONGODB

  • installation doc

    Set user and password for mongod:

     mongod
 
 >-------------
 use admin
 >
 switched to db admin
 >

 db.createUser(
  {
   user: "admin",
   pwd: "password",
   roles: [ { role: "dbOwner", db: "db-name" } ]
  }
 )

    Network Binding:

    sudo ufw allow 27017

    sudo ufw allow from your_trusted_server_ip/32 to any port 27017

    To verify the changes in firewall settings, type:

    sudo ufw status

    Open the MongoDB configuration file in the editor:

    sudo nano /etc/mongod.conf
 
 >-----------------------------------------------------------------
 # mongod.conf

 # for documentation of all options, see:
 #   http://docs.mongodb.org/manual/reference/configuration-options/

 # Where and how to store data.
 # network interfaces
 net:
     port: 27017
     bindIp: 127.0.0.1

    Add your server's IP address to net.bindIp:

    # network interfaces  
net:
 port: 27017
 bindIp: 127.0.0.1,your_trusted_server_ip

    And restart

    sudo service mongod restart

    If you have issue with mongodb, run following cmd:

    chown -R mongodb:mongodb /var/lib/mongodb
chown mongodb:mongodb /tmp/mongodb-27017.sock
sudo systemctl enable mongod
sudo service mongod restart
sudo service mongod status
  1. Check memory usage: 
    htop
