Recently, one of my friend reaching out to me regarding how to install the P2P-Lending on a GCE instance. Well, the repo is old and haven’t updated for more than 3 years. So I have overcome many difficulties to manage run it in a GCE instance. Here are the steps:

  1. Create GCE instances with allow HTTP traffic (using defaul Debian image if using other Linux distros the following preparation may not fit).
  2. Install NodeJs, followed steps in: https://cloud.google.com/nodejs/docs/setup
    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
    export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
    [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
    nvm install --lts
    nvm use --lts
  3. Install npm/git/python2 via command (for build-in python3 please ensure it >= 3.6 or upgrade to the latest):
    sudo apt install git build-essential python
    npm install -g npm
  4. To avoid permission denied issue when calling the npm installed global package, please follow this link to resolve it:
     mkdir ~/.npm-global
     npm config set prefix '~/.npm-global'
     export PATH=~/.npm-global/bin:$PATH
     source ~/.profile
  5. Install Ganache via command: npm install ganache -g
  6. Install Truffle via command: npm install truffle -g
  7. Clone the repo: git clone https://github.com/adorsys/p2p-lending.git
  8. Start Ganache with port 8545: ganache -p 8545 &
  9. Go to p2p-lending folder, and delete the packge-lock.json file (force to pull the latest packages):
    cd p2p-lending
    rm package-lock.json
    npm install
    truffle compile
    npm run migrate:dev
  10. [Optional] Set python executable, require python2 if not installed: npm config set /usr/bin/python
  11. In frontend folder, modify package.json, change the package web version from “1.0.0-beta.37” to “^1.0.0”. Then follow commands to install:
    cd frontend
    npm uninstall node-sass
    npm i -D sass
    rm -rf node_modules package-lock.json && npm install
  12. Start the serve: npm start

That’s it. Hope it could provide some insights when you try to use the P2P-Lending, but strongly not recommended. Since I’m not familar with blockchain, so not sure if there is any alternative to the P2P-Lending. If anyone knows, please share in the comments. I will let my friend know. Thanks in advance.
