How To Install Golang compiler on Ubuntu

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


$ sudo tar -xvf go1.6.linux-amd64.tar.gz


$ sudo mv go /usr/local


$ sudo vim ~/.profile


At the end of the file, add this line:

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


$ export GOROOT=$HOME/go

$ export PATH=$PATH:$GOROOT/bin


$ source ~/.profile


Create a new directory for your Go workspace, which is where Go will build its files.

$ mkdir $HOME/work


$ export GOPATH=$HOME/work


$ mkdir -p work/src/github.com/user/hello


$ vim work/src/github.com/user/hello/hello.go


Inside your editor, paste in the content below, which uses the main Go packages,
imports the formatted IO content component,
and sets a new function to print 'Hello World' when run.

package main

import "fmt"

func main() {
    fmt.Printf("hello, world\n")
}



compile it invoking the Go command install.

$ go install github.com/user/hello

The file compiled, you can run it by simply referring to the file at your Go path.

$ sudo $GOPATH/bin/hello
