I thought I would put this quick tutorial together to help out anyone interested in contributing a node to the Nimiq network, also feel free to sign up using my referral link which will give you a $10 credit - https://m.do.co/c/0e575aa2cb44
requires some basic shell skills
First steps
- Create a droplet and pick an operating system (we'll Use Ubuntu as an example)
- Select a droplet size (If you are mining expect to get around 1 to 1.5kh/s per cpu core for a standard droplet)
- Once the droplet is created, be sure to configure your desired domain name's dns settings to point to the assigned ip address for the droplet. In this example we'll be using
nimiq.example.com
Open a shell session to the machine (w/ ssh or through DigitalOceans web console)
The Nimiq team has provided a debian package for easy installation. We'll use the latest download link, but best to go to the downloads page and follow the instructions there. (v 1.1.2 at time of writing)
wget https://repo.nimiq.com/deb/pool/main/n/nimiq/nimiq_1.1.2-1_amd64.deb
dpkg -i nimiq_1.1.2-1_amd64.deb
Letsencrypt is an easy when to install a free SSL cert and supports automatic renewal. I've found the nginx distribution to be the best and not cause any issues. https://certbot.eff.org/lets-encrypt/ubuntuxenial-nginx
apt-get update
apt-get install software-properties-common
add-apt-repository ppa:certbot/certbot
apt-get update
apt-get install python-certbot-nginx
Creating the certificate is a simple command
certbot --nginx -d nimiq.example.com
Register your email and answer the questions that are prompted. When complete, take note of the paths to the certificate files.
ex.
/etc/letsencrypt/live/nimiq.example.com/fullchain.pem
/etc/letsencrypt/live/nimiq.example.com/privkey.pem
installing the certs as the root user requires permissions to be changed to allow the nimiq service to read the certificate files.
chmod 755 /etc/letsencrypt/live
chmod 755 /etc/letsencrypt/archive
The nimiq configuration file can be found at /etc/nimiq/nimiq.conf
, use nano or vi to open and edit the file
nano /etc/nimiq/nimiq.conf
ensure the appropriate host and paths to cert files are configured properly, ex.
{
"host": "nimiq.example.com",
"tls": {
"cert": "/etc/letsencrypt/live/nimiq.example.com/fullchain.pem",
"key": "/etc/letsencrypt/live/nimiq.example.com/privkey.pem"
},
"statistics": 60,
"mining": {
"enabled": "yes"
},
"wallet": {
"address": "NQ24 XX.."
},
"poolMining": {
"enabled": "yes",
"host": "pool.nimiq.watch",
"port": 8443
}
}
Once configured, simply save the file (ctrl + O for nano) and restart the Nimiq service
systemctl restart nimiq
You can see the status by running systemctl status nimiq
