Introduction
Running a NEM node on the network does not require a huge amount of computational power. Because NEM uses POI rather than POW we can run a node on some of the most basic of hardware.
Setting up the Debian
Create a Swap File :
Run the following command as root on your Debian droplet:
allocate -l 4G /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile
Check the new amount of total memory:
free -m
Make the Swap File permanent
Edit the file with root privileges in your text editor:
nano /etc/fstab
At the bottom of the file, you need to add a line that will tell the operating system to automatically use the file you created:
swapfile none swap sw 0 0
Java Installation:
The first thing we will need is Java. If you have the noobs os preloaded you will have this and can skip ahead, if not you will need to run the following commands into terminal:
echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main" | tee /etc/apt/sources.list.d/webupd8team-java.list
echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main" | tee -a /etc/apt/sources.list.d/webupd8team-java.list
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys EEA14886
apt-get update
apt-get install oracle-java8-installer
Download and configure NIS
wget https://bob.nem.ninja/nis-0.6.95.tgz
tar -xvzf nis-0.6.95.tgz
rm nis-0.6.95.tgz
mkdir nis-ncc
mv package nis-ncc/package
Edit : config.properties
cd nis-ncc/package/nis
nano config.properties
nis.bootName: name of the NIS node (you can use anything you like)
nis.bootKey = XXX
Start boot service on VPS :
cd /etc/init.d
nano startbootnode.sh
#!/bin/bash
### BEGIN INIT INFO # Provides: firewall # Required-Start: $remote_fs $syslog # Required-Stop: $remote_fs $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Démarre les règles iptables # Description: Charge la configuration du pare-feu iptables ### END INIT INFO#!/bin/shcd ~/nis-ncc/package
./nix.runNis.sh
Then run at startup :
chmod +x startbootnode.sh
update-rc.d startbootnode.sh defaults
Restart Debian, ready !
