Install Tendermint

From Binary

To download pre-built binaries, see the releases page.

From Source

You’ll need go installed and the required environment variables set

Get Source Code

mkdir -p $GOPATH/src/github.com/tendermint
cd $GOPATH/src/github.com/tendermint
git clone https://github.com/tendermint/tendermint.git
cd tendermint

Get Tools & Dependencies

make get_tools
make get_vendor_deps

Compile

make install

to put the binary in $GOPATH/bin or use:

make build

to put the binary in ./build.

The latest tendermint version is now installed.

Reinstall

If you already have Tendermint installed, and you make updates, simply

cd $GOPATH/src/github.com/tendermint/tendermint
make install

To upgrade, there are a few options:

  • set a new $GOPATH and run go get github.com/tendermint/tendermint/cmd/tendermint. This makes a fresh copy of everything for the new version.
  • run go get -u github.com/tendermint/tendermint/cmd/tendermint, where the -u fetches the latest updates for the repository and its dependencies
  • fetch and checkout the latest master branch in $GOPATH/src/github.com/tendermint/tendermint, and then run make get_vendor_deps && make install as above.

Note the first two options should usually work, but may fail. If they do, use dep, as above:

cd $GOPATH/src/github.com/tendermint/tendermint
make get_vendor_deps
make install

Since the third option just uses dep right away, it should always work.

Run

To start a one-node blockchain with a simple in-process application:

tendermint init
tendermint node --proxy_app=kvstore
