Install Tendermint

From Binary

To download pre-built binaries, see the releases page (opens new window).

From Source

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

Copy echo export GOPATH=\"\$HOME/go\" >> ~/.bash_profile echo export PATH=\"\$PATH:\$GOPATH/bin\" >> ~/.bash_profile echo export GO111MODULE=on >> ~/.bash_profile

Get Source Code

Copy 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

Copy make tools

Compile

Copy make install

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

Copy 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:

Copy tendermint version

Run

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

Copy tendermint init tendermint node --proxy_app=kvstore

Reinstall

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

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

To upgrade, run

Copy cd $GOPATH/src/github.com/tendermint/tendermint git pull origin master make install

Compile with CLevelDB support

Install LevelDB (opens new window) (minimum version is 1.7).

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

Copy 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:

Copy # config/config.toml db_backend = "cleveldb"

To install Tendermint, run:

Copy CGO_LDFLAGS="-lsnappy" make install TENDERMINT_BUILD_OPTIONS=cleveldb

or run:

Copy CGO_LDFLAGS="-lsnappy" make build TENDERMINT_BUILD_OPTIONS=cleveldb

which puts the binary in ./build.
