Install Tendermint

From Binary

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

Using Homebrew

You can also install the Tendermint binary by simply using homebrew,

brew install tendermint

From Source

You'll need go installed and the required environment variables set, which can be done with the following commands:

echo export GOPATH=\"\$HOME/go\" >> ~/.bash_profile
echo export PATH=\"\$PATH:\$GOPATH/bin\" >> ~/.bash_profile

Get the source code:

git clone https://github.com/tendermint/tendermint.git
cd tendermint

Then run:

make install

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

make build

to put the binary in ./build.

DISCLAIMER The binary of Tendermint is build/installed without the DWARF symbol table. If you would like to build/install Tendermint with the DWARF symbol and debug information, remove -s -w from BUILD_FLAGS in the make file.

The latest Tendermint is now installed. You can verify the installation by running:

tendermint version

Run

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

tendermint init validator
tendermint start --proxy-app=kvstore

Reinstall

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

make install

To upgrade, run

git pull origin master
make install

Compile with CLevelDB support

Install LevelDB (minimum version is 1.7).

Install LevelDB with snappy (optionally). Below are commands for Ubuntu:

sudo apt-get update
sudo apt install build-essential

sudo apt-get install libsnappy-dev

wget https://github.com/google/leveldb/archive/v1.20.tar.gz && \
  tar -zxvf v1.20.tar.gz && \
  cd leveldb-1.20/ && \
  make && \
  sudo cp -r out-static/lib* out-shared/lib* /usr/local/lib/ && \
  cd include/ && \
  sudo cp -r leveldb /usr/local/include/ && \
  sudo ldconfig && \
  rm -f v1.20.tar.gz

Set a database backend to cleveldb:

# config/config.toml
db_backend = "cleveldb"

To install Tendermint, run:

CGO_LDFLAGS="-lsnappy" make install TENDERMINT_BUILD_OPTIONS=cleveldb

or run:

CGO_LDFLAGS="-lsnappy" make build TENDERMINT_BUILD_OPTIONS=cleveldb

which puts the binary in ./build.
