Install Go

Galaxy is built using Go and requires Go version 1.16+. In this example, we will be installing Go on the above Ubuntu 18.04:

# First remove any existing old Go installation
sudo rm -rf /usr/local/go

# Install Go
wget https://go.dev/dl/go1.16.6.linux-amd64.tar.gz

# Decompress.
# You may need sudo permission.
tar -C /usr/local -xzf go1.16.6.linux-amd64.tar.gz

# Update environment variables to include go
cat <<'EOF' >>$HOME/.profile
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
EOF
source $HOME/.profile

To verify that Go is installed:

go version
# Should return go version go1.16.6 linux/amd64

Get Galaxy Source Code

Use git to retrieve Galaxy source code from the official repo, and checkout the v1.0.0 tag, which contains the latest stable release.

git clone https://github.com/galaxynetwork/galaxy
cd galaxy
git checkout v1.0.0

Install galaxyd

You can now build Galaxy node software. Running the following command will install the executable galaxyd (Galaxy node daemon) to your GOPATH.

make install

Galaxyd Version

galaxyd version --long

name: galaxy
server_name: galaxyd
version: v1.0.0
commit: 941005fd26071b8018bb2107be1077b12e242c88
build_tags: netgo,ledger
go: go version go1.16.6 linux/amd64

If the software version does not match, then please check your $PATH to ensure the correct galaxyd is running.

Save your Chain ID in galaxyd config

We recommend saving the mainnet chain-id into your galaxyd's client.toml. This will make it so you do not have to manually pass in the chain-id flag for every CLI command.

galaxyd config chain-id galaxy-1

Initialize your Node

Now that your software is installed, you can initialize the directory for galaxyd.

galaxyd init <your_moniker>

This will create a new .galaxyd folder in your HOME directory.
