VPS and Hot wallet Setup

These instructions are intended for advanced users that are setting up a MasterNode Hot wallet on a Linux VPS and don’t want to waste time with all those pesky details and explanations.

Order and setup a Linux VPS

  1. Identify a VPS provider and order a Linux Ubuntu 16.04 or 18.04 x64 server.

    Recommended VPS Providers:

VPS Minimum Requirements:
  • Linux - Ubuntu 16.04/18.04 - 64 Bit OS
  • 1GB of RAM
  • 20GB of disk space
  • Dedicated Public IP Address
  1. Login to the VPS provider website and configure the external firewall to allow SSH port 22 and the Rupaya Wallet TCP port 9050.

  2. Login to the VPS, via SSH, as the root user.

  3. Install Linux updates:

    apt install make
    apt install aptitude -y
    apt-get update -y
    apt-get upgrade -y
    
  4. OPTIONAL STEP: Install fail2ban and create modifiable configs for fail2ban and its jail settings:

    apt-get install fail2ban -y
    cp /etc/fail2ban/fail2ban.conf /etc/fail2ban/fail2ban.local
    cp /etc/fail2ban/jail.conf /etc/fail2ban/jail.local
    
  5. OPTIONAL STEP: Install tzdata. Run the following command to install the application that will allow you to select your clock timezone:

    apt install tzdata
    
  6. OPTIONAL STEP: Set your time zone. Run the following command to set your preferred time zone:

    dpkg-reconfigure tzdata
    
  7. Configure a virtual swap space on the VPS to avoid running out of memory:

    fallocate -l 3000M /mnt/3000MB.swap
    dd if=/dev/zero of=/mnt/3000MB.swap bs=1024 count=3072000
    mkswap /mnt/3000MB.swap
    swapon /mnt/3000MB.swap
    chmod 600 /mnt/3000MB.swap
    echo '/mnt/3000MB.swap  none  swap  sw 0  0' >> /etc/fstab
    
  8. Configure the VPS internal firewall to allow SSH port 22 and the Rupaya Wallet port 9050:

    apt-get -qq install ufw
    ufw default deny incoming
    ufw default allow outgoing
    ufw allow 22/tcp
    ufw limit 22/tcp
    ufw allow 9050/tcp
    ufw logging on
    ufw --force enable
    
  9. Reboot the Linux VPS:

    reboot
    
  10. Reconnect to the Linux VPS and login as root.

    • NOTE: It will take 2 to 3 minutes for the VPS to reboot.

Create a New User and Login as rupxmn

OPTIONAL STEP: The following steps (1 - 3) are optional. These steps are strongly recommended for those that want to implement security best practices. These steps are recommended so that the Hot wallet is not installed under the root user account.

  1. Create a new user named rupxmn and assign a password to the new user:

    useradd -m -s /bin/bash rupxmn
    passwd rupxmn
    
  2. Grant root access to the new user rupxmn:

    usermod -aG sudo rupxmn
    
  3. Login as the new user rupxmn:

    login rupxmn
    

Download and Configure the Rupaya Hot wallet

  1. Install the Rupaya Hot wallet on the VPS by running the following commands one at a time:

    wget https://github.com/rupaya-project/rupx/releases/download/v5.1.1/rupaya-5.1.1-x86_64-linux-gnu.tar.gz
    tar -xvf rupaya-5.1.1-x86_64-linux-gnu.tar.gz --strip-components 2
    rm rupaya-5.1.1-x86_64-linux-gnu.tar.gz
    sudo mv rupayad rupaya-cli /usr/local/bin/
    
  2. Start the Hot wallet:

    rupayad -daemon
    
  3. Generate the MasterNode private key (aka GenKey):

    rupaya-cli masternode genkey
    
  4. Copy and save the MasterNode private key (GenKey) from the previous command to be used later in the process:

  5. Stop the Hot wallet with the rupaya-cli stop command:

    rupaya-cli stop
    
  6. Copy the following rupaya.conf template, paste it into a text editor, and update the variables manually.

  • Use the following template for IPv4 IP Addresses:

    rpcuser=rupayarpc
    rpcpassword=<alphanumeric_rpc_password>
    rpcport=7050
    rpcallowip=127.0.0.1
    rpcconnect=127.0.0.1
    rpcbind=127.0.0.1
    maxconnections=512
    listen=1
    daemon=1
    masternode=1
    externalip=<public_mn_ip_address_here>:9050
    masternodeaddr=<public_mn_ip_address_here>
    bind=<public_mn_ip_address_here>
    masternodeprivkey=<your_masternode_genkey_output>
    
  • Use the following template for IPv6 IP Addresses:

    rpcuser=rupayarpc
    rpcpassword=<alphanumeric_rpc_password>
    rpcport=7050
    rpcallowip=127.0.0.1
    rpcconnect=127.0.0.1
    rpcbind=127.0.0.1
    maxconnections=512
    listen=1
    daemon=1
    masternode=1
    externalip=[<public_mn_ip_address_here>]:9050
    masternodeaddr=[<public_mn_ip_address_here>]
    bind=[<public_mn_ip_address_here>]
    masternodeprivkey=<your_masternode_genkey_output>
    
  1. Edit the MasterNode Hot wallet configuration file ~/.rupayacore/rupaya.conf:

    nano ~/.rupayacore/rupaya.conf
    
  2. Paste the updated template into the rupaya.conf configuration file on the Linux VPS.

  3. Save and exit the file by typing CTRL+X and hit Y + ENTER to save your changes.

  4. Restart the Hot wallet with the rupayad -daemon command:

    rupayad -daemon
    

Download the Bootstrap from a Linux VPS Using a Bash Script

OPTIONAL STEP: This section is intended for those that want to install the bootstrap on a Linux VPS using a bash script, which will automate the process.

  1. Login to the Linux VPS as the user that will be running the wallet.
  2. Run the following commands, one at a time, to download and run the bash script:
  • For those running the wallet as the user rupxmn, use the following commands:

    wget https://raw.githubusercontent.com/BlockchainBrain/Rupaya_Bootstrap/master/rupxmn-bootstrap.sh
    bash rupxmn-bootstrap.sh
    
  • For those running the wallet as the user root, use the following commands:

    wget https://raw.githubusercontent.com/BlockchainBrain/Rupaya_Bootstrap/master/root-bootstrap.sh
    bash root-bootstrap.sh
    
  1. Verify that the wallet is running and that the block count is above 177000:

    rupaya-cli getinfo
    
  • NOTE: It may take a few minutes for connections to begin to establish. Don’t be alarmed if the initial output shows “blocks”: -1

Download the Bootstrap Manually from the Linux VPS

OPTIONAL STEP: This section is intended for those that want to manually install the bootstrap on a Linux VPS. YOU DO NOT NEED TO REPEAT THIS STEP IF YOU ALREADY INSTALLED THE BOOTSTRAP USING THE BASH SCRIPT.

  1. Login to the Linux VPS as the user that will be running the wallet.

  2. Close the Rupaya wallet:

    rupaya-cli stop && sleep 10
    
  3. Run the following commands to delete the old rupayacore files and folders, without deleting the rupaya.conf file:

    cp ~/.rupayacore/rupaya.conf .
    sudo rm -rf ~/.rupayacore
    mkdir ~/.rupayacore
    mv rupaya.conf ~/.rupayacore/.
    
  4. Run the following command to download the bootstrap:

    wget https://www.dropbox.com/s/hqmmf5wo6gpbq1b/rupx-bootstrap-160119.zip
    
  5. Install Unzip:

    sudo apt-get install unzip -y
    
  6. Unzip the bootstrap folders and files into the .rupayacore folder:

    unzip rupx-bootstrap-160119.zip -d ~/.rupayacore
    
  7. Restart the wallet:

    rupayad -daemon
    
  8. Delete the bootstrap.zip file:

    rm rupx-bootstrap-160119.zip
    

Verify the Hot wallet is synchronizing with the blockchain

  1. Run the rupaya-cli getinfo command to make sure that you see active connections:

    rupaya-cli getinfo
    
  • NOTE: It may take a few minutes for connections to begin to establish. Don’t be alarmed if the initial output shows “blocks”: -1
  1. Run the rupaya-cli getblockcount command every few mins until you see the blocks increasing:

    rupaya-cli getblockcount
    
  • NOTE: If your block count is NOT increasing then you will need to stop the Hot wallet with the rupaya-cli stop command and then reindex with the rupayad -reindex command.
  • NOTE: If you did the reindex and you continue to have issues with establishing connections then check that the VPS provider external firewall is setup correctly to allow TCP port 9050 from anywhere. If that is not setup correctly then you will not be able to proceed beyond this step.

If your block count is indeed increasing, then you can proceed to the next step to setup the Cold wallet.
