How To Install Full Node DECENTR MAINNET

Setting up vars

Your Nodename (validator) that will shows in explorer

NODENAME=<Your_Nodename_Moniker>
DECENTR_PORT=32

Save variables to system

echo "export NODENAME=$NODENAME" >> $HOME/.bash_profile
if [ ! $WALLET ]; then
	echo "export WALLET=wallet" >> $HOME/.bash_profile
fi
echo "export DECENTR_CHAIN_ID=mainnet-3" >> $HOME/.bash_profile
echo "export DECENTR_PORT=${DECENTR_PORT}" >> $HOME/.bash_profile
source $HOME/.bash_profile

Update packages

sudo apt update && sudo apt upgrade -y

Install dependencies

sudo apt install curl build-essential git wget jq make gcc tmux net-tools ccze -y

Install go

  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
fi

Download and build binaries

cd $HOME && rm -rf decentr
git clone https://github.com/Decentr-net/decentr.git && cd decentr
git checkout v1.6.2
make install

Config app

decentrd config chain-id $DECENTR_CHAIN_ID
decentrd config node tcp://localhost:32657

set custom ports

sed -i.bak -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:${DECENTR_PORT}658\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:${DECENTR_PORT}657\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:${DECENTR_PORT}060\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:${DECENTR_PORT}656\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":${DECENTR_PORT}660\"%" $HOME/.decentr/config/config.toml

Init app

decentrd init $NODENAME --chain-id $DECENTR_CHAIN_ID

Download configuration

cd $HOME

curl -Ls https://raw.githubusercontent.com/konsortech/Node/main/Mainnet/Decentr/addrbook.json > $HOME/.decentr/config/addrbook.json

Set seeds and peers

sed -E -i 's/seeds = \".*\"/seeds = \"[e-mail]:26656,[e-mail]:26656,[e-mail]:26656,[e-mail]:26656,[e-mail]:26656,[e-mail]:26656,[e-mail]:26656,[e-mail]:26656,[e-mail]:26656,[e-mail]:26656\"/' $HOME/.decentr/config/config.toml

Disable indexing

indexer="null"
sed -i -e "s/^indexer *=.*/indexer = \"$indexer\"/" $HOME/.decentr/config/config.toml

Config pruning

pruning="custom"
