ver="1.22.3"
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"

go version

Sett Vars

to make installation easy i suggest u use this

echo "export WALLET="wallet"" >> $HOME/.bash_profile
echo "export MONIKER="Moiker"" >> $HOME/.bash_profile
echo "export LUMERA_CHAIN_ID="lumera-testnet-1"" >> $HOME/.bash_profile
echo "export LUMERA_PORT="31"" >> $HOME/.bash_profile
source $HOME/.bash_profile

make sure you change "Wallet="with your own wallet name"" MONIKER="with your own name"" this indicate your node name LUMERA_PORT="with you want"" if your server is not have any node u can keep that at port 30 or sett to deffault port, the deffault port is 26.
