Build NATS Server from Source

The NATS server code is available as open source software under the MIT license. You can build the source to run the NATS server on any platform supported by Go. The NATS server code requires at least version 1.4 of Go. You are encouraged to run the latest stable release of Go.

2. Create and change into $GOPATH/src/github.com/nats-io directory.

cd $GOPATH/src

mkdir -p github\.com/nats-io && cd github.com/nats-io

3. Clone the NATS server repository.

git clone git@github.com:nats-io/gnatsd.git

4. Change to the gnatsd directory you cloned.

cd $GOPATH/src/github.com/nats-io/gnatsd

5. View the NATS server source code.

View the main.go file.

cat main.go

6. Build the server from source.

Run go build from inside the gnatsd directory.

cd gnatsd

go build

7. Start nats-server.

./gnatsd

A successful build run produces no messages and creates an executable called gnatsd in this directory.

You can invoke this binary, with no options and no configuration file for local testing. To start a server with acceptable production defaults please read our README.md.
