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¶
Identify a VPS provider and order a Linux Ubuntu 16.04 server.
Login to the VPS provider website and configure the external firewall to allow SSH port 22 and the Liberty Wallet TCP port 10417.
Login to the VPS, via SSH, as the root user.
Install Linux updates:
apt install make apt install aptitude -y apt-get update -y apt-get upgrade -y
Install fail2ban and create modifiable configs for fail2ban and its jail settings. Run these commands one at a time to install basic ssh protection with fail2ban:
apt-get install fail2ban -y cp /etc/fail2ban/fail2ban.conf /etc/fail2ban/fail2ban.local cp /etc/fail2ban/jail.conf /etc/fail2ban/jail.local
Install tzdata. Run the following command to install the application that will allow you to select your clock timezone:
apt install tzdata
Set your time zone. Run the following command to set your preferred time zone:
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
Configure the VPS internal firewall to allow SSH port 22 and the Liberty Wallet port 10417:
ufw allow 22/tcp ufw limit 22/tcp ufw allow 10417/tcp ufw logging on ufw --force enable
Create a New User and Login as xlibmn¶
Create a new user named xlibmn and assign a password to the new user:
useradd -m -s /bin/bash xlibmn passwd xlibmn
Grant root access to the new user xlibmn:
usermod -aG sudo xlibmn
Login as the new user xlibmn:
Download and Configure the Liberty Hot wallet¶
Install the Liberty Hot wallet on the VPS:
wget https://s3.amazonaws.com/liberty-builds/18.104.22.168/linux-x64.tar.gz sudo tar xvzf linux-x64.tar.gz -C /usr/local/bin/
Start the Hot wallet:
Generate the MasterNode private key (aka GenKey):
Copy and save the MasterNode private key (GenKey) from the previous command to be used later in the process:
Stop the Hot wallet with the liberty-cli stop command:
Copy the liberty.conf template, paste it into a text editor, and update the variables manually:
rpcuser=Libertyrpc rpcpassword=<alphanumeric_rpc_password> rpcport=10416 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>:10417 masternodeaddr=<public_mn_ip_address_here> masternodeprivkey=<your_masternode_genkey_output>
Edit the MasterNode Hot wallet configuration file ~/.liberty/liberty.conf:
Paste the updated template into the liberty.conf configuration file on the Linux VPS.
Save and exit the file by typing CTRL+X and hit Y + ENTER to save your changes.
Restart the Hot wallet with the libertyd -daemon command:
Verify the Hot wallet is synchronizing with the blockchain¶
Run the liberty-cli getinfo command to make sure that you see active connections:
Run the liberty-cli getblockcount command every few mins until you see the blocks increasing:
- NOTE: If your block count is NOT increasing then you will need to stop the Hot wallet with the liberty-cli stop command and then reindex with the libertyd -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 10417 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.
