This is a quick tutorial for those wanting to host a NOIA node on a virtual box for example. I have used Vultr for this purpose and setup a Ubuntu 16.04 VM.
If you are interested in signing up on Vultr too, you could use my ref link to sign up. Otherwise just browse to Vultr and sign up.
If you need help setting up a VM, contact me here.
We need to make sure that systemd is being used for managing deamons. Run the following command. If your system is using upstart, please refer to this great tutorial
ps -p 1 -o comm=
If you haven't got one already, create an ERC20 wallet here: MEW
Node JS and NPM are required for the noia node to run. Install using the commands below
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt-get install -y nodejs
sudo apt-get install build-essential
///START This part is taken from the official NOIA documentation. Credits to NOIA.
Install the noia node package globally
$ npm install @noia-network/node-cli -g
If installation fails with administrator rights, then try suppressing the UID/GID switching when running the install command:
$ npm install @noia-network/node-cli -g --unsafe-perm
///END
Find the node.settings file on your system using
find / -type f -name "node.settings"
For me it was sitting in
/root/.noia-node/node.settings
Open the file using vi
vi /root/.noia-node/node.settings
and edit the masterAddress to match the following:
master-address=wss://csl-masters.noia.network:5565
Also edit the airdropAddress if you want to receive the node rewards :). Make sure to input your own ERC20 Wallet!!
airdropAddress=0xfe1ADFa5d31d3F7da12465d1A56823Cd68C03188
You can now try the following
noia-node-cli start
It should output something like the following:
info: [noia-node] Initializing NOIA node, settings-path=/root/.noia-node/node.settings.
info: [noia-node] Storage dir=/root/.noia-node/storage, allocated=104857600.
(node:480) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 change listeners added. Use emitter.setMaxListeners() to increase limit
info: [noia-node] NOIA node initialized.
info: [noia-node] Connecting to master (without blockchain), master-address=wss://csl-masters.noia.network:5565.
Create a file called noia-node.service in the directory: /etc/systemd/system, adjust its execution rights chmod 664 /etc/systemd/system/noia-node.service and restart the systemctl daemon using: systemctl daemon-reload
Copy the following contents to your service file and ajust the ExecStart and WorkinDirectory paths to your node and noia installation paths. In my case:
[Unit]
Description=NOIA Node
[Service]
ExecStart=/usr/bin/node /usr/local/lib/node_modules/@noia-network/node-cli/dist/index.js
Restart=always
User=root
Group=root
Environment=PATH=/usr/bin:/usr/local/bin
Environment=NODE_ENV=production
WorkingDirectory=/usr/local/lib/node_modules/@noia-network/node-cli
Environment=NOIA_NODE_USER_DATA_PATH=/root/.noia-node
[Install]
WantedBy=multi-user.target
Restart the deamon
systemctl daemon-reload
systemctl enable noia-node.service
systemctl start noia-node.service
To check whether the node is running type
systemctl | grep noia
You should see something like this:
noia-node.service loaded active running NOIA Node
Also you need to check this:
sudo systemctl status noia-node.service
If noia is running successfull, it returns something like this:
root@vultr:~# sudo systemctl status noia-node.service
● noia-node.service - NOIA Node
Loaded: loaded (/etc/systemd/system/noia-node.service; enabled; vendor preset: enabled)
Active: active (running) since Thu 2019-07-18 09:46:50 UTC; 3 weeks 3 days ago
Try running the following to get more information on the possible error:
journalctl -u noia-node.service
You can also try:
sudo systemctl status noia-node.service
If noia is running successfull, it returns something like this:
root@vultr:~# sudo systemctl status noia-node.service
● noia-node.service - NOIA Node
Loaded: loaded (/etc/systemd/system/noia-node.service; enabled; vendor preset: enabled)
Active: active (running) since Thu 2019-07-18 09:46:50 UTC; 3 weeks 3 days ago
Try setting in the node.settings file
natpmp=true
I created a new directory below my home directory. You can create it anywhere you like though. I will be using the path: /home/noia in this tutorial.
git clone https://github.com/noia-network/noia-node-terminal.git
cd /home/noia/noia-node-terminal
This is enough to test the installation using:
npm install
npm run build
npm start
A couple of things will happen, in the end you should get an error though. Something like this:
[NODE]: initialized.
[NODE]: starting...
/home/noia/noia-node-terminal/node_modules/noia-node/dist/lib/master.js:66
throw new Error("master address null or undefined");
^
Error: master address null or undefined
at Master.connect (/home/noia/noia-node-terminal/node_modules/noia-node/dist/lib/master.js:66:19)
at Node.start (/home/noia/noia-node-terminal/node_modules/noia-node/dist/index.js:74:25)

at Object.Module._extensions..js (internal/modules/cjs/loader.js:713:10)

at tryModuleLoad (internal/modules/cjs/loader.js:551:12)

at Function.Module.runMain (internal/modules/cjs/loader.js:744:10)
at startup (internal/bootstrap/node.js:238:19)
If you get a different error, you need to debug - make sure latest npm and nodejs versions are installed
Having run the command above, should have generated a settings.json file within your noia-node-terminal folder. Open that file and adjust a couple of settings as described below:
nano settings.json
Adjust the line for masterAddress to match this:
"masterAddress": "ws://csl-masters.noia.network:5565"
Adjust the line for wallet.address to match this:
"wallet.address": "Your ERC20 wallet address"
Test the node again by running npm start
Now you should some logging of [info] message about your configuration such as this line:
info: [noia-node] Creating wire... interface=gui, node_ip=yourip, node_ws_port=7676, node_domain=, node_wallet_address=your ETH address
You should not see any error messages at this point. If you do, please make sure you have executed all steps from above correctly. Theoretically you can now let this run, but we want the node to be running as a service in the background and startup automatically when the machine reboots for example.
Open the noia-node.service file provided within your installation path
nano noia-node.service
Adjust the ExecStart and WorkinDirectory paths to your node and noia installation paths. See an example of my service file witin this repo.
Once done, copy the service file to your /etc/systemd/system directory, adjust its execution rights and restart the systemctl daemon.
cp /home/noia/noia-node-terminal/noia-node.service /etc/systemd/system/
chmod 664 /etc/systemd/system/noia-node.service
systemctl daemon-reload
systemctl enable noia-node.service
systemctl start noia-node.service
To check whether the node is running type
systemctl | grep noia
You should see something like this:
noia-node.service loaded active running NOIA Node
