Setup Cosmovisor

// install cosmovisor
go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@latest

// make genesis directory
mkdir -p ~/.elys/cosmovisor/genesis/bin
// make upgrades directory
mkdir -p ~/.elys/cosmovisor/upgrades

// get elys daemon location
which elysd
// you should now getting the elysd location, for example like: ~/go/bin/elysd
// copy to genesis directory
cp YourBinaryLocation ~/.elys/cosmovisor/genesis/bin/ 

Running as services with cosmovisor

// Get your cosmovisor binary location
which cosmovisor
// you should now getting the cosmovisor location, for example like: ~/go/bin/cosmovisor
// save this cosmovisor binary location

// create services
sudo nano /etc/systemd/system/elysd.service
