Install a Tierion (TNT) Node under CentOS 7

So you bought some Tierion and want to set up a Node to help the network. These instructions are for CentOS 7 (should work the same in RHEL).

So go to your favorite VPS provider, some examples are:

https://www.hostwinds.com/

https://www.digitalocean.com/

https://www.vultr.com/

And set up a VPS (Virtual Private Server), as OS select CentOS 7. Minimum requirements for the VPS are:

• 512MB RAM
• 1 CPU Core
• 20GB Hard Disk or SSD
• Public IPv4 address

Once the OS (Operating System) is installed login as root to your shell:

yum update -y

Install Docker (https://docs.docker.com/engine/installation/linux/docker-ce/centos/ ):  

yum install -y yum-utils device-mapper-persistent-data lvm2 nano

cd /etc/yum.repos.d/ 

wget https://download.docker.com/linux/centos/docker-ce.repo 

yum update -y 

yum install docker-ce 

# Install compose 

yum install docker-compose -y 

systemctl start docker 

Test your installation:

 docker run hello-world 

Within the response you should see the following text:
“Hello from Docker! This message shows that your installation appears to be working correctly.”

Create the user you will be running the Node with:

useradd USERNAME

# Set the user password

passwd USERNAME

# Give the user access to docker without sudo

usermod -aG docker USERNAME

Now to install Chainpoint:

# Go to your user login

su - USERNAME

# At the home directory type

git clone https://github.com/chainpoint/chainpoint-node

cd chainpoint-node

make build-config

nano .env

Look for the following at the end of the text file:
NODE_TNT_ADDRESS=
CHAINPOINT_NODE_PUBLIC_URI=

NODE_TNT_ADDRESS should have your MyEtherWallet address (public key), this is the address from where you will send your TNT to buy Credits

CHAINPOINT_NODE_PUBLIC_URI has to be set to your public IP or DNS, remember to start it with http://

Now to start the service

make up

# Now this will take some time...

# There is a private key you have to back up

docker-compose logs | grep "back me up"

# Write Down the key, do not loose it!

Your node is now running. There are a bunch of commands you can use:

# Start Node service

make up

# Stop Node service

make down

# Verify Node is running

make ps

# if the service is NOT up, it may be you forgot the "http://" in CHAINPOINT_NODE_PUBLIC_URI

# View Node Logs

make logs

# View how many (count) hashes have been sent

docker-compose logs | grep -c "Hash submitted to Core"

Now you still need to buy your credits, from your EtherWallet (MEW or other) with the same address that you used in NODE_TNT_ADDRESS you will send at least 54 TNT to a Tierion address. Review this link: https://keybase.pub/tierion/chainpoint-security.txt (make sure you send TNT and not ETH, also use 36984 as Gas Limit)

To check if the Tierion Network got your funds you can use this link: https://ethplorer.io/address/0xddfff2b78463ab1ca781e853bb888fdfd06083d3 (or change the address to the destination address you used).

To view your credits use any of the following links: 

• https://a.chainpoint.org/nodes/[YOUR_ETH_ADDRESS]
• https://b.chainpoint.org/nodes/[YOUR_ETH_ADDRESS]
• https://c.chainpoint.org/nodes/[YOUR_ETH_ADDRESS]
