Installing Cardano-node

Latest version 1.19.1


Set up your platform:

You will need:

  • An x86 host (AMD or Intel), Virtual Machine or AWS instance with at least 2 cores, 4GB of RAM and at least 10GB of free disk space;

  • A recent version of Linux, not Windows or MacOS – this will help us isolate any issues that arise.

  • Make sure you are on a network that is not firewalled. In particular, we will be using TCP/IP port 3000 and 3001 by default to establish connections with other nodes, so this will need to be open.

Install dependencies

We need the following packages and tools on our Linux system to download the source code and build it:

  • the version control system git,

  • the gcc C-compiler,

  • C++ support for gcc,

  • developer libraries for the the arbitrary precision library gmp,

  • developer libraries for the compression library zlib,

  • developer libraries for systemd,

  • developer libraries for ncurses,

  • ncurses compatibility libraries,

  • the Haskell build tool cabal,

  • the GHC Haskell compiler.

If we are using an AWS instance running Amazon Linux AMI 2 (see the AWS walk-through for how to get such an instance up and running)or another CentOS/RHEL based system, we can install these dependencies as follows:

sudo yum update -y
sudo yum install git gcc gcc-c++ tmux gmp-devel make tar wget -y
sudo yum install zlib-devel libtool autoconf -y
sudo yum install systemd-devel ncurses-devel ncurses-compat-libs -y

For Debian/Ubuntu use the following instead:

sudo apt-get update -y
sudo apt-get install build-essential pkg-config libffi-dev libgmp-dev -y
sudo apt-get install libssl-dev libtinfo-dev libsystemd-dev zlib1g-dev -y
sudo apt-get install make g++ tmux git jq wget libncursesw5 libtool autoconf -y

If you are using a different flavor of Linux, you will need to use the package manager suitable for your platform instead of yum or apt-get, and the names of the packages you need to install might differ.

Download, unpack, install and update Cabal:

tar -xf cabal-install-
rm cabal-install- cabal.sig
mkdir -p ~/.local/bin
mv cabal ~/.local/bin/

Verify that .local/bin is in your PATH

echo $PATH

If .local/bin is not in the PATH, you need to add the following line to your .bashrcfile

Navigate to your home folder:


Open your .bashrc file with nano text editor

nano .bashrc

Go to the bottom of the file and add the following lines

export PATH="~/.local/bin:$PATH"

You need to restart your server or source your .bashrc file

source .bashrc

Update cabal

cabal update

Above instructions install Cabal version You can check the version by typing

cabal --version

Download and install GHC:

tar -xf ghc-8.6.5-x86_64-deb9-linux.tar.xz
rm ghc-8.6.5-x86_64-deb9-linux.tar.xz
cd ghc-8.6.5
sudo make install
cd ..

Install Libsodium

git clone
cd libsodium
git checkout 66f017f1
sudo make install
export LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH"
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH"

Download the source code for cardano-node

git clone

This creates the folder cardano-node and downloads the latest source code.

After the download has finished, we can check its content by

ls cardano-node

We change our working directory to the downloaded source code folder:

cd cardano-node

For reproducible builds, we should check out a specific release, a specific "tag". For the Shelley Testnet, we will use tag 1.19.1, which we can check out as follows:

git fetch --all --tags
git tag
git checkout tags/1.19.1

Build and install the node

Now we build and install the node with cabal, which will take a couple of minutes the first time you do a build. Later builds will be much faster, because everything that does not change will be cached.

cabal build all

Now we can copy the executables files to the .local/bin directory

cp -p dist-newstyle/build/x86_64-linux/ghc-8.6.5/cardano-node-1.19.1/x/cardano-node/build/cardano-node/cardano-node ~/.local/bin/
cp -p dist-newstyle/build/x86_64-linux/ghc-8.6.5/cardano-cli-1.19.1/x/cardano-cli/build/cardano-cli/cardano-cli ~/.local/bin/
cardano-cli --version

f you need to update to a newer version follow the steps below. This will be much faster than the initial build:

cd cardano-node
git fetch --all --tags
git tag
git checkout tags/<the-tag-you-want>
cabal install cardano-node cardano-cli

Note: It might be necessary to delete the db-folder (the database-folder) before running an updated version of the node.
