This blog represents steps required to get started with Go programming language on Linux/Ubuntu. The details can be found on this Golang – Getting Started page.

Setup Go & Configure

The following instructions can be used to setup Go which includes installation and configuration:

  • Download the appropriate binary release from Go Download Page; In case of Linux, download go1.9.*.tar.gz.
  • Go to the download folder and execute the following command: 
    tar -C /usr/local -xzf go$VERSION.$OS-$ARCH.tar.gz

    For the latest version of Go, the above command would look like following:

    tar -C /usr/local -xzf go1.9.linux-amd64.tar.gz

    Above command would setup go at the location, /usr/local.

  • Configure path appropriately such that Go can be used to run the programs from anywhere on the system. Set following in ~/.bashrc file. 
    export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin

    Once done, execute the .bashrc to put the settings in effect in current terminal.

    . ~/.bashrc

Create Hello World Program using Go Programming Language

  • Create a project folder structure such as following: ~/goapp/src/hello
  • Create a file namely hello.go with following code, in the src/hello folder: 
    package main

import "fmt"

func main() {
  fmt.Printf("hello, world\n")
}
  • Build the Hello.go program 
    go build
  • Run the program 
    ./hello

Execution of above program should print hello, world
