Installing Smilo mainnet node on Ubuntu Linux

This time we are going to install the Smilo Go Client, it will allow act as a node that you will be able to connect to via the web3.js library on the client.

Create your VPS on your favorite cloud using a Ubuntu +16.04

Install go-smilo

apt-get install software-properties-common  
add-apt-repository -y ppa:smilo/smilo  
apt-get update && apt-get install smilo

Create the smilo user:

adduser smilo

Lets configure smilo geth to start on reboot and to restart after 30s when crashing for some reason.

nano /lib/systemd/system/smilo.service

Copy in

[Unit] Description=Smilo Go Client 
[Service] ExecStart=/usr/bin/sgeth --fast --cache=512 --nocompaction --datadir=/home/smilo/blockchain --sport --rpc --rpcapi=web3,db,net,eth 
Restart=always 
RestartSec=30 
Type=simple 
User=smilo 
Group=smilo 
[Install] 
WantedBy=multi-user.target

and Ctrl + X to save it and then reload it with:

systemctl daemon-reload 
systemctl enable smilo.service

Start it up and let’s have a look and see what magic happened

journalctl -u sgeth -n20

Now we have to wait a bit for it to synchronize with Smilo Mainnet, just let it run.

Are we done already? lets check if the sync process is completed:

geth attach ipc:/home/smilo/blockchain/geth.ipc

Get the complete status

eth.syncing

Run this script on the geth console to get a periodic report on the sync status:

setInterval(function(){var s = eth.syncing; console.log("%"+( s.currentBlock/s.highestBlock*100).toFixed(3)) }, 1000);

The sync will run on fast mode, we expect it to start fast and then slow down a bit towards the end.

From time to time you can check the block number

journalctl -u geth -n40

Once we are up to date, we have our Smilo node available for use on a VPS server. Easy, no ? :)
