Installation
Core lightning is available on many platforms and environments. Learn how to install on your preferred platform.
Binaries
If you're on Ubuntu, you need to install bitcoind:
sudo apt-get install -y software-properties-common
sudo snap install bitcoin-core
sudo snap refresh --hold bitcoin-core # To prevent automated update of bitcoin-core
sudo ln -s /snap/bitcoin-core/current/bin/bitcoin{d,-cli} /usr/local/bin/
Then you can fetch a pre-compiled binary from the releases page on GitHub. Core Lightning provides binaries for both Ubuntu and Fedora distributions. Normally these binaries are extracted into /usr/local:
sudo tar -xvf <release>.tar.xz -C /usr/local --strip-components=2
If you're on a different distribution or OS, you can compile the source by following the instructions from Installing from Source.
Docker
To install the Docker image for the latest stable release:
docker pull elementsproject/lightningd:latest
To install for a specific version, for example, 24.05:
docker pull elementsproject/lightningd:v24.05
See all of the docker images for Core Lightning on Docker Hub.
Third-party apps
For a GUI experience, you can install and use Core Lightning via a variety of third-party applications such as Ride the Lightning, Umbrel, BTCPayServer, Raspiblitz, Embassy.
Core Lightning is also available on nixOS via the nix-bitcoin project.
Installing from source
To build Core Lightning in a reproducible way, follow the steps at Reproducible builds for Core Lightning.
Library Requirements
You will need several development libraries:
- libsqlite3: for database support.
- zlib: for compression routines.
For actually doing development and running the tests, you will also need:
- pip3: to install python-bitcoinlib
- valgrind: for extra debugging checks
You will also need a version of bitcoind with segregated witness and estimatesmartfee
with ECONOMICAL
mode support, such as the 0.16 or above.
To Build on Ubuntu
OS version: Ubuntu 15.10 or above
Get dependencies:
sudo apt-get update
sudo apt-get install -y \
jq autoconf automake build-essential git libtool libsqlite3-dev libffi-dev \
python3 python3-pip net-tools zlib1g-dev libsodium-dev gettext
pip3 install --upgrade pip
pip3 install --user poetry
If you don't have Bitcoin installed locally you'll need to install that as well. It's now available via snapd.
sudo apt-get install snapd
sudo snap install bitcoin-core
# Snap does some weird things with binary names; you'll
# want to add a link to them so everything works as expected
sudo ln -s /snap/bitcoin-core/current/bin/bitcoin{d,-cli} /usr/local/bin/
Clone lightning:
git clone https://github.com/ElementsProject/lightning.git
cd lightning
Checkout a release tag:
git checkout v24.05
For development or running tests, get additional dependencies:
sudo apt-get install -y valgrind libpq-dev shellcheck cppcheck \
libsecp256k1-dev lowdown
pip3 install pytest
If you can't install lowdown
, a version will be built in-tree.
If you want to build the Rust plugins (currently, cln-grpc):
sudo apt-get install -y cargo rustfmt protobuf-compiler
There are two ways to build core lightning, and this depends on how you want use it.
To build cln to just install a tagged or master version you can use the following commands:
pip3 install --upgrade pip
pip3 install mako
pip3 install grpcio-tools
./configure
make
sudo make install
If you want disable Rust because you do not want use it or simple you do not want the grpc-plugin, you can use
./configure --disable-rust
.
To build core lightning for development purpose you can use the following commands:
pip3 install poetry
poetry shell
This will put you in a new shell to enter the following commands:
poetry install
./configure
make
make check VALGRIND=0
Optionally, add -j$(nproc)
after make
to speed up compilation. (e.g. make -j$(nproc)
)
Running lightning:
bitcoind &
./lightningd/lightningd &
./cli/lightning-cli help
To Build on Fedora
OS version: Fedora 27 or above
Get dependencies:
sudo dnf update -y && \
sudo dnf groupinstall -y \
'C Development Tools and Libraries' \
'Development Tools' && \
sudo dnf install -y \
clang \
gettext \
git \
gmp-devel \
libsq3-devel \
python3-devel \
python3-pip \
python3-setuptools \
net-tools \
valgrind \
wget \
jq \
zlib-devel \
libsodium-devel && \
sudo dnf clean all
Make sure you have bitcoind available to run.
Clone lightning:
git clone https://github.com/ElementsProject/lightning.git
cd lightning
Checkout a release tag:
git checkout v24.05
Build and install lightning:
./configure
make
sudo make install
Running lightning (mainnet):
bitcoind &
lightningd --network=bitcoin
Running lightning on testnet:
bitcoind -testnet &
lightningd --network=testnet
To Build on FreeBSD
OS version: FreeBSD 11.1-RELEASE or above
pkg install git python py39-pip gmake libtool gmp sqlite3 postgresql13-client gettext autotools
https://github.com/ElementsProject/lightning.git
pip install --upgrade pip
pip3 install mako
./configure
gmake -j$(nproc)
gmake install
Alternatively, Core Lightning is in the FreeBSD ports, so install it as any other port (dependencies are handled automatically):
# pkg install c-lightning
If you want to compile locally and fiddle with compile time options:
# cd /usr/ports/net-p2p/c-lightning && make install
See /usr/ports/net-p2p/c-lightning/Makefile
for instructions on how to build from an arbitrary git commit, instead of the latest release tag.
Make sure you've set an utf-8 locale, e.g.
export LC_CTYPE=en_US.UTF-8
, otherwise manpage installation may fail.
Running lightning:
Configure bitcoind, if not already: add rpcuser=<foo>
and rpcpassword=<bar>
to /usr/local/etc/bitcoin.conf
, maybe also testnet=1
.
Configure lightningd: copy /usr/local/etc/lightningd-bitcoin.conf.sample
to
/usr/local/etc/lightningd-bitcoin.conf
and edit according to your needs.
# service bitcoind start
# service lightningd start
# lightning-cli --rpc-file /var/db/c-lightning/bitcoin/lightning-rpc --lightning-dir=/var/db/c-lightning help
To Build on OpenBSD
OS version: OpenBSD 7.3
Install dependencies:
pkg_add git python gmake py3-pip libtool gettext-tools
pkg_add automake # (select highest version, automake1.16.2 at time of writing)
pkg_add autoconf # (select highest version, autoconf-2.69p2 at time of writing)
Install mako
otherwise we run into build errors:
pip3.8 install --user poetry
poetry install
Add /home/<username>/.local/bin
to your path:
export PATH=$PATH:/home/<username>/.local/bin
Needed for configure
:
export AUTOCONF_VERSION=2.69
export AUTOMAKE_VERSION=1.16
./configure
Finally, build c-lightning
:
gmake
To Build on NixOS
Use nix-shell launch a shell with a full Core Lightning dev environment:
nix-shell -Q -p gdb sqlite autoconf git clang libtool sqlite autoconf \
autogen automake gmp zlib gettext libsodium poetry 'python3.withPackages (p: [p.bitcoinlib])' \
valgrind --run "./configure && poetry shell"
poetry install
make
To Build on macOS
Assuming you have Xcode and Homebrew installed. Install dependencies:
brew install autoconf automake libtool python3 gnu-sed gettext libsodium protobuf
ln -s /usr/local/Cellar/gettext/0.20.1/bin/xgettext /usr/local/opt
export PATH="/usr/local/opt:$PATH"
If you need SQLite (or get a SQLite mismatch build error):
brew install sqlite
export LDFLAGS="-L/usr/local/opt/sqlite/lib"
export CPPFLAGS="-I/usr/local/opt/sqlite/include"
Some library paths are different when using homebrew
on Macs with Apple silicon, therefore the following two variables need to be set for Macs with Apple silicon:
export CPATH=/opt/homebrew/include
export LIBRARY_PATH=/opt/homebrew/lib
If you need Python 3.x for mako (or get a mako build error):
brew install pyenv
echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n eval "$(pyenv init -)"\nfi' >> ~/.bash_profile
source ~/.bash_profile
pyenv install 3.8.10
pip install --upgrade pip
pip install poetry
If you don't have bitcoind installed locally you'll need to install that as well:
brew install berkeley-db4 boost miniupnpc pkg-config libevent
git clone https://github.com/bitcoin/bitcoin
cd bitcoin
./autogen.sh
./configure
make src/bitcoind src/bitcoin-cli && make install
Clone lightning:
git clone https://github.com/ElementsProject/lightning.git
cd lightning
Checkout a release tag:
git checkout v24.05
Build lightning:
poetry install
./configure
poetry run make
Running lightning:
Edit your
~/Library/Application\ Support/Bitcoin/bitcoin.conf
to includerpcuser=<foo>
andrpcpassword=<bar>
first, you may also need to includetestnet=1
.
bitcoind &
./lightningd/lightningd &
./cli/lightning-cli help
To install the built binaries into your system, you'll need to run make install
:
make install
On a Mac with Apple silicon, you may need to use this command instead:
sudo PATH="/usr/local/opt:$PATH" LIBRARY_PATH=/opt/homebrew/lib CPATH=/opt/homebrew/include make install
To Build on Arch Linux
Install dependencies:
pacman --sync autoconf automake gcc git make python-pip
pip install --user poetry
Clone Core Lightning:
git clone https://github.com/ElementsProject/lightning.git
cd lightning
Build Core Lightning:
python -m poetry install
./configure
python -m poetry run make
Launch Core Lightning:
./lightningd/lightningd
To cross-compile for Android
Make a standalone toolchain as per https://developer.android.com/ndk/guides/standalone_toolchain.html.
For Core Lightning you must target an API level of 24 or higher.
Depending on your toolchain location and target arch, source env variables such as:
export PATH=$PATH:/path/to/android/toolchain/bin
# Change next line depending on target device arch
target_host=arm-linux-androideabi
export AR=$target_host-ar
export AS=$target_host-clang
export CC=$target_host-clang
export CXX=$target_host-clang++
export LD=$target_host-ld
export STRIP=$target_host-strip
Two makefile targets should not be cross-compiled so we specify a native CC:
make CC=clang clean ccan/tools/configurator/configurator
make clean -C ccan/ccan/cdump/tools \
&& make CC=clang -C ccan/ccan/cdump/tools
Install the qemu-user
package.
This will allow you to properly configure the build for the target device environment.
Build with:
BUILD=x86_64 MAKE_HOST=arm-linux-androideabi \
make PIE=1 \
CONFIGURATOR_CC="arm-linux-androideabi-clang -static"
To cross-compile for Raspberry Pi
Obtain the official Raspberry Pi toolchains. This document assumes compilation will occur towards the Raspberry Pi 3 (arm-linux-gnueabihf as of Mar. 2018).
Depending on your toolchain location and target arch, source env variables will need to be set. They can be set from the command line as such:
export PATH=$PATH:/path/to/arm-linux-gnueabihf/bin
# Change next line depending on specific Raspberry Pi device
target_host=arm-linux-gnueabihf
export AR=$target_host-ar
export AS=$target_host-as
export CC=$target_host-gcc
export CXX=$target_host-g++
export LD=$target_host-ld
export STRIP=$target_host-strip
Install the qemu-user
package. This will allow you to properly configure the
build for the target device environment.
Config the arm elf interpreter prefix:
export QEMU_LD_PREFIX=/path/to/raspberry/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/arm-linux-gnueabihf/sysroot/
Obtain and install cross-compiled versions of sqlite3 and zlib:
Download and build zlib:
wget https://zlib.net/fossils/zlib-1.2.13.tar.gz
tar xvf zlib-1.2.13.tar.gz
cd zlib-1.2.13
./configure --prefix=$QEMU_LD_PREFIX
make
make install
Download and build sqlite3:
wget https://www.sqlite.org/2018/sqlite-src-3260000.zip
unzip sqlite-src-3260000.zip
cd sqlite-src-3260000
./configure --enable-static --disable-readline --disable-threadsafe --disable-load-extension --host=$target_host --prefix=$QEMU_LD_PREFIX
make
make install
Then, build Core Lightning with the following commands:
./configure
make
To compile for Armbian
For all the other Pi devices out there, consider using Armbian.
You can compile in customize-image.sh
using the instructions for Ubuntu.
A working example that compiles both bitcoind and Core Lightning for Armbian can
be found here.
To compile for Alpine
Get dependencies:
apk update
apk add --virtual .build-deps ca-certificates alpine-sdk autoconf automake git libtool \
sqlite-dev python3 py3-mako net-tools zlib-dev libsodium gettext
Clone lightning:
git clone https://github.com/ElementsProject/lightning.git
cd lightning
git submodule update --init --recursive
Build and install:
./configure
make
make install
Clean up:
cd .. && rm -rf lightning
apk del .build-deps
Install runtime dependencies:
apk add libgcc libsodium sqlite-libs zlib
Python plugins
Python plugins will be installed with the poetry install
step mentioned above fron development setup.
Other users will need some Python packages if python plugins are used. Unfortunately there are some Python packages which are not packaged in Ubuntu, and so force installation will be needed (Flag --user
is recommended which will install them in user's own .local directory, so at least the risk of breaking Python globally can be avoided!).
clnrest
Installation steps for clnrest are:
sudo apt-get install python3-json5 python3-flask python3-gunicorn
pip3 install --user flask-cors flask-restx pyln-client flask-socketio gevent gevent-websocket
wss-proxy
Below libraries are required for wss-proxy:
pip3 install --user pyln-client websockets
