You'll need go installed 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

# Get Source Code

Copy 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 make install

To upgrade, run

Copy 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:

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.
