INSTALL
=======
1. Login to your Ubuntu system using ssh and upgrade to apply latest security updates there.
$ sudo apt-get update
$ sudo apt-get -y upgrade

2. Download the Go language binary archive file using following link.
https://golang.org/dl/
$ wget https://storage.googleapis.com/golang/go1.9.2.linux-amd64.tar.gz

3. Extract the downloaded archive and install it to the desired location on the system. For this tutorial, I am installing it under /usr/local directory. You can also put this under the home directory (for shared hosting) or other location.
$ sudo tar -xvf go1.9.2.linux-amd64.tar.gz
$ sudo mv go /usr/local

SETUP
=====
You need to set 3 environment variables as GOROOT, GOPATH and PATH

GOROOT is the location where Go package is installed on your system.
$ export GOROOT=/usr/local/go

GOPATH is the location of your work directory. For example my project directory is ~/dev/GoProjects .
$ export GOPATH=$HOME/dev/GoProjects

Now set the PATH variable to access go binary system wide.
$ export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

To make it permanent add above commands in ~/.profile file:
export GOROOT=/usr/local/go
export GOPATH=$HOME/dev/GoProjects
# set PATH so it includes user's private bin directories
PATH="$HOME/bin:$HOME/.local/bin:$PATH"
export PATH=$PATH:/home/tno/dev/ethereum/geth/bin
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH
