Installing the node from source

The latest version of the node may be downloaded from the cardano-node GitHub Releases page.

Prerequisites

To set up your platform, you will need:

Network CPU Cores Free RAM Free storage OS for Pasive Node OS for Stake pool
Mainnet 2 24GB 150GB of free storage (250GB recommended for future growth) Linux / Windows** / MacOS Linux
Testnet 2 4GB 20GB Linux / Windows** / MacOS Linux

**Note If you are building on Windows, we recommend using WSL2 under Windows 10 as this provides a development and execution environment that is very similar to Ubuntu.

System dependencies installation

To download the source code and build it, you need the following packages and tools on your Linux system:

  • the version control system git,
  • the gcc C-compiler,
  • C++ support for gcc,
  • developer libraries for 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 (version 8.10.7 or above).

In Redhat, Fedora, and Centos:

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

For Debian/Ubuntu:

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

Possible issue with pkg-config:

pkgconf 1.9.5 (which is default in Fedora 39 and Rawhide) produces output unreadable by cabal, which results in an errors like:

conflict: pkg-config package libsodium-any, not found in the pkg-config database

despite having libsodium installed in the system.

The possible solutions to this problem are:

  • to upgrade pkgconf to version 2 by building it from source:

    yum update -y && \
yum install git diffutils gcc gcc-c++ tmux gmp-devel make tar xz wget zlib-devel libtool autoconf -y && \
mkdir -p /root/src/ && cd /root/src && \
curl -O https://distfiles.ariadne.space/pkgconf/pkgconf-2.0.3.tar.xz && \
tar -xvf pkgconf-2.0.3.tar.xz && \
cd pkgconf-2.0.3 && \
./configure && make && make install && \

  • to use cabal version (higher than 3.10.2.0) that have these changes already integrated:

Optional dependencies that may be required: llvm libnuma-dev

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

For MacOS:

You'll need the following packages and tools on your MacOS system:

  • Xcode - The Apple Development IDE and SDK/Tools
  • Xcode Command Line Tools, you can install it by typing xcode-select --install in the terminal.
  • Homebrew - The Missing Package Manager for MacOS (or Linux)

Then using homebrew install the following:

brew install jq libtool autoconf automake pkg-config openssl

You will need to install llvm in case you are using M1

brew install llvm@13

Installing the Haskell environment

The recommended way to install the Haskell tools is via GHCup. Its installation script will guide you through the installation, and warn you about packages that you have to make sure are installed in the system (the ones described on the step above). Check this page for further explanation on the installation process.

Once GHCup is installed, open a new terminal (to get an updated environment) and run:

ghcup install ghc 8.10.7
ghcup install cabal 3.8.1.0
ghcup set ghc 8.10.7
ghcup set cabal 3.8.1.0

Alternatively, with ghcup tui you can pick the specific versions of the tools that you want to install, in particular you should have installed and set:

  • cabal >= 3.8.1.0
  • GHC >= 8.10.7

To check that you will use the GHCup tools (and not any other installation on the system), you can execute

which cabal

and it should return a path of this shape: /home/<user>/.ghcup/bin/cabal.

Installing dependencies

Decide which version of Cardano Node you will be installing. A list of available tags is available at: https://github.com/IntersectMBO/cardano-node/tags. Set the environment variable to the tag you selected (or use master for the latest unstable version):

CARDANO_NODE_VERSION='8.7.3'
IOHKNIX_VERSION=$(curl https://raw.githubusercontent.com/IntersectMBO/cardano-node/$CARDANO_NODE_VERSION/flake.lock | jq -r '.nodes.iohkNix.locked.rev')
echo "iohk-nix version: $IOHKNIX_VERSION"

The variable IOHKNIX_VERSION is used to retrieve the correct versions of sodium, secp256k1 and blst.

Caution

Make sure that secp256k1, sodium and blst versions match flake input version in iohkNix for a particular node version used.

Installing sodium

Cardano uses a custom fork of sodium which exposes some internal functions and adds some other new functions. This fork lives in https://github.com/intersectmbo/libsodium. Users need to install that custom version of sodium with the following steps.

Create a working directory for your builds:

mkdir -p ~/src
cd ~/src

Find out the correct sodium version for your build:

SODIUM_VERSION=$(curl https://raw.githubusercontent.com/input-output-hk/iohk-nix/$IOHKNIX_VERSION/flake.lock | jq -r '.nodes.sodium.original.rev')
echo "Using sodium version: $SODIUM_VERSION"

Download and install sodium:

: ${SODIUM_VERSION:='dbb48cc'}
git clone https://github.com/intersectmbo/libsodium
cd libsodium
git checkout $SODIUM_VERSION
./autogen.sh
./configure
make
make check
sudo make install

Add the following to your ~/.bashrc file and source it (or re-open the terminal):

export LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH"
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH"

For some distributions you will also need to configure the dynamic linker. If the executable is linked with the right libsodium.so file (which you can check by running ldd), the running binary might still use the wrong library. You can check this by running pldd. If the pldd shows that the running executable is using the wrong library, run ldconfig.

Using the ported c code for development

Warning

The ported c code should not be used to run the node, and should only be used for development purposes.

In order to avoid having to install the custom version of libsodium for development purposes, cardano-crypto-praos defines a cabal flag that makes use of C code located here.

The C code is merely a port of the bits missing in a normal libsodium installation. To enable this code, one has to add the following code in the cabal.project.local file:

package cardano-crypto-praos
  flags: -external-libsodium-vrf

For this to work, libsodium has to be in the system. For Ubuntu, this is achieved by:

sudo apt install libsodium-dev

Installing secp256k1

Find out the correct secp256k1 version:

SECP256K1_VERSION=$(curl https://raw.githubusercontent.com/input-output-hk/iohk-nix/$IOHKNIX_VERSION/flake.lock | jq -r '.nodes.secp256k1.original.ref')
echo "Using secp256k1 version: ${SECP256K1_VERSION}"

Download and install secp256k1:

: ${SECP256K1_VERSION:='v0.3.2'}
git clone --depth 1 --branch ${SECP256K1_VERSION} https://github.com/bitcoin-core/secp256k1
cd secp256k1
./autogen.sh
./configure --enable-module-schnorrsig --enable-experimental
make
make check
sudo make install

Installing blst

Find out the correct blst version:

BLST_VERSION=$(curl https://raw.githubusercontent.com/input-output-hk/iohk-nix/master/flake.lock | jq -r '.nodes.blst.original.ref')
echo "Using blst version: ${BLST_VERSION}"

Download and install blst so that cardano-base can pick it up (assuming that pkg-config is installed):

: ${BLST_VERSION:='v0.3.11'}
git clone --depth 1 --branch ${BLST_VERSION} https://github.com/supranational/blst
cd blst
./build.sh
cat > libblst.pc << EOF
prefix=/usr/local
exec_prefix=\${prefix}
libdir=\${exec_prefix}/lib
includedir=\${prefix}/include

sudo cp libblst.a /usr/local/lib
sudo chmod u=rw,go=r /usr/local/{lib/{libblst.a,pkgconfig/libblst.pc},include/{blst.{h,hpp},blst_aux.h}}

Installing the node

Downloading the source code for cardano-node

Create a working directory for your builds:

mkdir -p ~/src
cd ~/src

Download the Cardano node sources:

git clone https://github.com/intersectmbo/cardano-node.git

Change the working directory to the downloaded source code folder:

cd cardano-node

Check out the latest version of cardano-node (choose the tag with the highest version number: TAGGED-VERSION):

git fetch --all --recurse-submodules --tags
git tag | sort -V
git checkout tags/<TAGGED VERSION>

Configuring the build options

We explicitly use the GHC version that we installed earlier. This avoids defaulting to a system version of GHC that might be different than the one you have installed.

echo "with-compiler: ghc-8.10.7" >> cabal.project.local

You will need to run following commands on M1, those commands will set some cabal related options before building

echo "package trace-dispatcher" >> cabal.project.local
echo "  ghc-options: -Wwarn" >> cabal.project.local
echo "" >> cabal.project.local

echo "package HsOpenSSL" >> cabal.project.local
echo "  flags: -homebrew-openssl" >> cabal.project.local
echo "" >> cabal.project.local

More recent versions of MacOS seems to install openssl in a different location than expected by default. If you have installed openssl via homebrew and encounter the following build error:

Failed to build HsOpenSSL-0.11.7.2. The failure occurred during the configure
step.
[1 of 1] Compiling Main (...)
Linking .../dist-newstyle/tmp/src-75805/HsOpenSSL-0.11.7.2/dist/setup/setup ...
Configuring HsOpenSSL-0.11.7.2...
setup: Can’t find OpenSSL library

You'll most likely need to add relevant symlinks as follows:

sudo mkdir -p /usr/local/opt/openssl
sudo ln -s /opt/homebrew/opt/openssl@3/lib /usr/local/opt/openssl/lib
sudo ln -s /opt/homebrew/opt/openssl@3/include /usr/local/opt/openssl/include

This is a wart of the HsOpenSSL library wrapper, and using classic methods such as setting LDFLAGS & CPPFLAGS, or using --extra-include-dirs and --extra-lib-dirs won't work properly.

Building and installing the node

Build the node and CLI with cabal:

cabal update
cabal build all
cabal build cardano-cli

Install the newly built node and CLI commands to the ~/.local/bin directory:

mkdir -p ~/.local/bin
cp -p "$(./scripts/bin-path.sh cardano-node)" ~/.local/bin/
cp -p "$(./scripts/bin-path.sh cardano-cli)" ~/.local/bin/

Note: If cardano-cli does not build with 'cabal build all', run 'cabal build cardano-cli'. Note: ~/.local/bin should be in the $PATH.

Note, we avoid using cabal install because that method prevents the installed binaries from reporting the git revision with the --version switch.

Check the version that has been installed:

cardano-cli --version

Repeat the above process when you need to update to a new version.

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