For Ubuntu 22.04 or later. The node listens on ports starting with your port prefix (e.g. 26657 becomes 13657), so several nodes can share a server.

  1. 01Install tools

    sudo apt update && sudo apt upgrade -y
sudo apt install -y curl git wget jq make gcc build-essential lz4 zstd tmux htop unzip

  2. 02Install Go

    cd $HOME
VER="<go-version>"
wget "https://golang.org/dl/go$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"
[ ! -f $HOME/.bash_profile ] && touch $HOME/.bash_profile
echo 'export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin' >> $HOME/.bash_profile
source $HOME/.bash_profile
mkdir -p $HOME/go/bin
go version

  3. 03Build the binary

    cd $HOME
rm -rf seda-chain
git clone https://github.com/sedaprotocol/seda-chain.git seda-chain
cd seda-chain
git checkout <version>
make install
sedad version --long | grep -E '^(version|commit):'

  4. 04Install Cosmovisor

    go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@latest
DAEMON_HOME=$HOME/.sedad DAEMON_NAME=sedad cosmovisor init $HOME/go/bin/sedad

  5. 05Create the service

    sudo tee /etc/systemd/system/sedad.service > /dev/null << EOF

sudo systemctl daemon-reload
sudo systemctl enable sedad

  6. 06Set variables

    echo 'export WALLET="wallet"' >> $HOME/.bash_profile
echo 'export MONIKER="Your-Moniker"' >> $HOME/.bash_profile
echo 'export SEDA_CHAIN_ID="<chain-id>"' >> $HOME/.bash_profile
echo 'export SEDA_PORT="13"' >> $HOME/.bash_profile
source $HOME/.bash_profile

  7. 07Initialize the node

    sedad init "$MONIKER" --chain-id $SEDA_CHAIN_ID --home $HOME/.sedad
sedad config set client chain-id $SEDA_CHAIN_ID
sedad config set client keyring-backend os
sedad config set client node tcp://localhost:$SEDA_PORT657

  8. 08Custom ports

    sed -i.bak -e "s%:1317%:$SEDA_PORT317%g;
s%:8080%:$SEDA_PORT080%g;
s%:9090%:$SEDA_PORT090%g;
