go PATH 설정

go 설치 

https://www.digitalocean.com/community/tutorials/how-to-install-go-1-6-on-ubuntu-14-04

sudo curl -O https://storage.googleapis.com/golang/go1.6.linux-amd64.tar.gz

Next, use tar to unpack the package. This command will use the Tar tool to open and expand the downloaded file, and creates a folder using the package name, and then moves it to /usr/local.

sudo tar -xvf go1.6.linux-amd64.tar.gz
sudo mv go /usr/local

Some users prefer different locations for their Go installation, or may have mandated software locations. The Go package is now in /usr/local which also ensures Go is in your $PATH for Linux. It is possible to install Go to an alternate location but the $PATH information will change. The location you pick to house your Go folder will be referenced later in this tutorial, so remember where you placed it if the location is different than /usr/local.

Step 2 — Setting Go Paths

In this step, we’ll set some paths that Go needs. The paths in this step are all given are relative to the location of your Go installation in /usr/local. If you chose a new directory, or left the file in download location, modify the commands to match your new location.

First, set Go's root value, which tells Go where to look for its files.

sudo nano ~/.profile

At the end of the file, add this line:

export PATH=$PATH:/usr/local/go/bin
