How to get Tezos¶
In this How To we explain how to get up-to-date binaries to run Tezos for each network. You can either use the docker images, which is easier, or build from sources.
The recommended way for running an up-to-date Tezos node is to use the
docker images that are automatically generated from the GitLab
repository and published on DockerHub.
alphanet.sh is provided to help download the right
image for each network and run a simple node.
Its only requirement is a working installation of Docker and docker compose on a machine with
Although we only officially support Linux, the script has been tested
with success in the past on windows/mac/linux.
The same script can be used to run Mainnet, Alphanet or Zeronet, it suffices to rename it as it downloads a different image based on its name. For example, to run Alphanet:
wget https://gitlab.com/tezos/tezos/raw/master/scripts/alphanet.sh chmod +x alphanet.sh
Alternatively, to run Mainnet:
wget -O mainnet.sh https://gitlab.com/tezos/tezos/raw/master/scripts/alphanet.sh chmod +x mainnet.sh
In the following we assume you are running Alphanet. You are now one step away from a working node:
This will download the right docker image for your chosen network, launch 3 docker containers running the node, the baker and the endorser. The first launch might take a few minutes to download the docker images and synchronize the chain.
Every call to
alphanet.sh will check for updates of the node and
will fail if your node is not up-to-date. For updating the node, simply
If you prefer to temporarily disable automatic updates, you just have to set an environment variable:
./alphanet.sh --help for more informations about the
script. In particular see
./alphanet.sh client --help or the
online manual for more information about
the client. Every command to the
tezos-client can be
equivalently executed using
Build from sources¶
TL;DR: Typically you want to do:
sudo apt install -y rsync git m4 build-essential patch unzip bubblewrap wget wget https://github.com/ocaml/opam/releases/download/2.0.0/opam-2.0.0-x86_64-linux sudo cp opam-2.0.0-x86_64-linux /usr/local/bin/opam sudo chmod a+x /usr/local/bin/opam git clone https://gitlab.com/tezos/tezos.git cd tezos git checkout alphanet opam init --bare make build-deps eval $(opam env) make export PATH=~/tezos:$PATH source ./src/bin_client/bash-completion.sh export TEZOS_CLIENT_UNSAFE_DISABLE_DISCLAIMER=Y
Currently Tezos is being developed for Linux x86_64, mostly for Debian/Ubuntu and Archlinux.
The following OSes are reported to work:
- Linux/armv7h (32 bits) (Raspberry Pi3, etc.)
- Linux/aarch64 (64 bits) (Raspberry Pi3, etc.)
A Windows port is feasible and might be developed in the future.
bubblewrap is not available in your distribution you can also
skip it and init opam with
Get the sources¶
You also need to choose the branch of the network you want to connect to: alphanet, zeronet or mainnet.
The master branch is where code is merged, but there is no test network using the master branch directly.
To compile Tezos, you need the OPAM package manager, version 2.0.0. This is the current latest version of OPAM and our build script will always use the latest released version (or prerelease) of OPAM. The build script will take care of setting-up OPAM, download the right version of the OCaml compiler, and so on.
opam init --bare to avoid compiling the OCaml compiler now: it
will be done in the next step.
Install Tezos dependencies with OPAM¶
Install the OCaml compiler and the libraries which Tezos depends on:
This command creates a local opam switch
_opam where the right
version of OCaml is compiled and installed (this takes a while but
it’s only done once).
After OCaml it will start with Tezos dependencies, OPAM is able to handle correctly the OCaml libraries but it is not always able to handle all external C libraries we depend on. On most system, it is able to suggest a call to the system package manager but it currently does not handle version check.
Once the dependencies are done we can update opam’s environment to refer to the new switch and compile the project:
eval $(opam env) make
Lastly you can also add Tezos binaries to your
activate bash autocompletion and after reading the Disclaimer a few
hundred times you are allowed to disable it with
To add the default opam repository at a lower priority (for example to install merlin or test other opam packages), you can use the following command:
opam repo add default --rank=-1
