Install go

We are gonna use GO Version 1.19.5 If you already have GO installed you can skip this

ver="1.19.5"
cd $HOME
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm "go$ver.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> ~/.bash_profile
source ~/.bash_profile
go version

Install binary

cd $HOME
git clone https://github.com/sge-network/sge
cd sge
git checkout v1.1.1
make install

Verify that you’ve installed sged successfully

sged version

Initialize Node

Please change <MONIKER> To your own Moniker.

sged init $MONIKER --chain-id sge-network-4
sged config chain-id sge-network-4
sged config keyring-backend test

Download Genesis file and addrbook

Genesis

wget -O $HOME/.sge/config/genesis.json "https://raw.githubusercontent.com/sge-network/networks/master/testnet/sge-network-4/genesis.json"

Addrbook

wget -O $HOME/.sge/config/addrbook.json "https://raw.githubusercontent.com/vinjan23/Testnet.Guide/main/SGE/addrbook.json"

create service file and start node

Create service file Create a ojod.service file in the /etc/systemd/system folder with the following code. You can change USER with your Linux user name. You need sudo previlege to do this step.

sudo tee /etc/systemd/system/sged.service > /dev/null <<EOF
[Unit]
Description=sge-testnet
After=network-online.target

[Service]
User=$USER
ExecStart=$(which sged) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

Enable Service and Start Node

sudo systemctl daemon-reload
sudo systemctl enable sged
sudo systemctl restart sged
sudo journalctl -u sged -f -o cat
