Stable Node Setup

Install dependencies

Install all required packages for building and running the node (compilers, utilities, monitoring tools, compression libraries).

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

Configure the setup

Set network parameters.

export CHAIN_ID=stable_988-1

Set your node moniker (name).

export MONIKER=MyNode

Set your node folder name.

export FOLDER=".stabled"

Set current release version.

export VER=

Create folder structure for releases and copy binary

Organize binaries by version, move the built binary, and create a symlink for the active release. ℹ️ During the next upgrade, create a new subfolder for the new binary inside the releases folder and simply update the active-release symlink to point to this new binary’s folder. This approach is convenient for both automatic and manual updates, as well as for quickly rolling back to the previous version. Read more

mkdir -p $HOME/$FOLDER/releases/$VER/bin
ln -sfn $HOME/$FOLDER/releases/$VER $HOME/$FOLDER/active-release

Set PATH environment

Add the active-release binary folder to your PATH so you can run stabled from anywhere.

echo "export PATH=${HOME}/${FOLDER}/active-release/bin:\$PATH" >> $HOME/.bash_profile
source $HOME/.bash_profile
echo "export PATH=${HOME}/${FOLDER}/active-release/bin:\$PATH" >> $HOME/.profile
source $HOME/.profile
