The Go programming language has gotten considerable momentum, and the fact that it compiles down to a single statically linked binary has made it popular in containers, where a single executable binary fits the execution model perfectly.
This article will detail installation on Ubuntu with the standard hello world validation.
Installation
First, download the latest 64 bit linux package from the download page. Unzip to the standard location, and run a quick check of the version.
cd /tmp
# grab latest version from download page
latest_version=$(curl -s https://go.dev/dl/ | grep -P 'download downloadBox' | grep linux-amd64 | grep -Po '/dl/go\K(.*)(?=\.linux-amd64.tar.gz)')
echo "latest golang version: $latest_version"
# download
wget https://storage.googleapis.com/golang/go${latest_version}.linux-amd64.tar.gz
# remove any older version, then extract latest
sudo rm -fr /usr/local/go
sudo tar -C /usr/local -xzf go${latest_version}.linux-amd64.tar.gz
# validate
/usr/local/go/bin/go version
Environment
Before going further, make sure to set the GOPATH and PATH variables to your environment.
On Ubuntu, append the following to ~/.profile:
export GOPATH=$HOME/work export PATH=$PATH:/usr/local/go/bin
Then create the subdirectories and source the profile so that your current environment is updated. Now you should be able to run go without needing to specify the path.
source ~/.profile echo "GOPATH is set to: $GOPATH" mkdir -p $GOPATH # validate go version
Hello World
Let’s start by going into the $GOPATH, and creating a source file.
mkdir -p $GOPATH/src/hello; cd $_
Create a file named $GOPATH/src/hello/hello.go
package main
import "fmt"
func main() {
fmt.Printf("Hello, world\n")
}
And then compile and run:
# build binary go build hello.go # run binary ./hello

NOTES
For statically linked
export CGO_ENABLED=0
On Windows
installer creates GOHOME and appends PATH
GOROOT=c:\go
PATH=$PATH;c:\go\bin
User should set new system var GOPATH=%userprofile%\go
