Elastos.ELA

Summary

Elacoin is the digital currency solution within Elastos eco system.

This project is the source code that can build a full node of ELA.

Build on Mac

Check OS version

Make sure the OSX version is 16.7+

$ uname -srm
Darwin 16.7.0 x86_64

Install Go distribution 1.9

Use Homebrew to install Golang 1.9.

$ brew install [email protected]

If you install older version, such as v1.8, you may get missing math/bits package error when build.

Setup basic workspace

In this instruction we use ~/dev/src/github.com/elastos as our working directory. If you clone the source code to a different directory, please make sure you change other environment variables accordingly (not recommended).

$ mkdir -p ~/dev/bin
$ mkdir -p ~/dev/src/github.com/elastos/

Set correct environment variables

export GOROOT=/usr/local/opt/[email protected]/libexec
export GOPATH=$HOME/dev
export GOBIN=$GOPATH/bin
export PATH=$GOROOT/bin:$PATH
export PATH=$GOBIN:$PATH

Install Glide

Glide is a package manager for Golang. We use Glide to install dependent packages.

$ brew install --ignore-dependencies glide

Check Go version and glide version

Check the golang and glider version. Make sure they are the following version number or above.

$ go version
go version go1.9.2 darwin/amd64

$ glide --version
glide version 0.13.1

If you cannot see the version number, there must be something wrong when install.

Clone source code to $GOPATH/src/github.com/elastos folder

Make sure you are in the folder of $GOPATH/src/github.com/elastos

$ git clone https://github.com/elastos/Elastos.ELA.git

If clone works successfully, you should see folder structure like $GOPATH/src/github.com/elastos/Elastos.ELA/Makefile

Glide install

cd $GOPATH/src/github.com/elastos/Elastos.ELA and Run glide update && glide install to install dependencies.

Make

cd $GOPATH/src/github.com/elastos/Elastos.ELA and Run make to build files.

If you did not see any error message, congratulations, you have made the ELA full node.

Run on Mac

• run ./ela to run the node program.

Build on Ubuntu

$ git clone https://github.com/elastos/Elastos.ELA.git

If clone works successfully, you should see folder structure like $GOPATH/src/github.com/elastos/Elastos.ELA/Makefile

Glide install

cd $GOPATH/src/github.com/elastos/Elastos.ELA and Run glide update && glide install to install dependencies.

Make

cd $GOPATH/src/github.com/elastos/Elastos.ELA and Run make to build files.

If you did not see any error message, congratulations, you have made the ELA full node.

Run on Ubuntu

• run ./ela to run the node program.

Config the node

See the documentation about config.json

Bootstrap using docker

Alternatively if don't want to build it manually. We also provide a Dockerfile to help you (You need have a prepared docker env).

cd docker
docker build -t ela_node_run .

#start container

docker run -p 20334:20334 -p 20335:20335 -p 20336:20336 -p 20338:20338 ela_node_run

Note: don't using Ctrl-C to terminate the output, just close this terminal and open another.

Now you can access ELA Node's rest api:

curl http://localhost:20334/api/v1/block/height

In the above instruction, we use default configuration file config.json in the repository; If you familiar with docker you can change the docker file to use your own ELA Node configuration.
