Deployed sites

• Alpha Mainnet: https://alpha.mainnet.bobcoin.cash
• Alpha Testnet: https://alpha.testnet.bobcoin.cash

Deploying to AWS EC2

After updated code is pushed to Github repository and ready to be deployed

ssh ec2-user@<ec2-ip-address> -i "<path-to-pem-file>"

cd /Bobcoin-Node

git pull

npm run build

pm2 restart 0

setup pm2

npm install pm2@latest -g

pm2 startup

Generate pm2 ecosystem file:

pm2 ecosystem

module.exports = {
  apps : [{
    name: 'Bobcoin Testnet Alpha',
    script: 'NODE_ENV=production npm start', // add --norecalc to skip cache recalculation
    watch: '.'
  }],
  deploy : {
    production : {
      user : 'SSH_USERNAME',
      host : 'SSH_HOSTMACHINE',
      ref  : 'origin/master',
      repo : 'GIT_REPOSITORY',
      path : 'DESTINATION_PATH',
      'pre-deploy-local': '',
      'post-deploy' : 'npm install && pm2 reload ecosystem.config.js --env production',
      'pre-setup': ''
    }
  }
};

Start node

pm2 start

pm2 save

pm2 logs

pm2 status

Maintainance

Check disk storage: df -h

Check pm2 log space: du -h ~/.pm2/pm2.log

Delete pm2 logs: pm2 flush

Configuring service (not needed with pm2)

Create systemd service sudo vim /etc/systemd/system/bobcoin.service

Paste this config into the file:

[Unit]
Description=Bobcoin Testnet Alpha
After=multi-user.target

[Service]
ExecStart=/home/ec2-user/.nvm/versions/node/v16.17.1/bin/node /home/ec2-user/Bobcoin-Node/dist/index.js
Restart=always
RestartSec=10
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=bobcoin-testnet-alpha
User=ec2-user
EnvironmentFile=/home/ec2-user/Bobcoin-Node/.env

[Install]
WantedBy=multi-user.target

Start service sudo systemctl start bobcoin.service

check status of service: sudo systemctl status bobcoin.service

enabled service, so it keeps running even when reboot: sudo systemctl enable bobcoin.service

Setup nginx

sudo amazon-linux-extras install nginx1 -y

sudo systemctl start nginx
sudo systemctl status nginx
sudo systemctl enable nginx

Modify config file

sudo vim /etc/nginx/nginx.conf

remove everything under "server_name", replace with

location / {
    proxy_pass http://localhost:3000;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    # WebSocket support
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

restart nginx

sudo systemctl restart nginx
