Golang, or just simply Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
This is way easier than you think !!

Step 1 - download

Firstly, let make sure our system is up-to-date
sudo apt update && sudo apt upgrade

No let’s download the go package:
Go to Go’s download page and grab a link for the latest version.
The version when I wrote this wee blog was go1.13.
Got the link? sweet! let’s download it:
wget https://dl.google.com/go/go1.13.linux-amd64.tar.gz

Now let’s untar it
tar xvfz go1.13.linux-amd64.tar.gz

And move it to an appropriate place (like /usr/local maybe?)
sudo mv go /usr/local/go

Step 2 - setup your environment

We’re going to add a few environment variables in our .bashrc, and add to our $PATH.
so let’s do that

cat << EOF >> ~/.bashrc
export GOROOT=/usr/local/go
export GOPATH=$HOME/goProjects
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

EOF

and then create our goProjects directory:
mkdir ~/goProjects

and finally, let’s reload our environment:
source ~/.bashrc

What we’ve done is:

  • Told our bash environment where to find go
  • Told our bash environment where our working directory is (~/goProjects)
  • added two directories to our $PATH

Step 3 - verify your install

Here comes the easy bit, let’s check our installed go version:
go version

go version go1.13 linux/amd64

and let’s check our go environment
go env

GO111MODULE=""
GOARCH="amd64"
GOBIN=""
GOCACHE="/home/paul/.cache/go-build"
GOENV="/home/paul/.config/go/env"
GOEXE=""
GOFLAGS=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GONOPROXY=""
GONOSUMDB=""
GOOS="linux"
GOPATH="/home/paul/goProjects"
GOPRIVATE=""
GOPROXY="https://proxy.golang.org,direct"
GOROOT="/usr/local/go"
GOSUMDB="sum.golang.org"
GOTMPDIR=""
GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64"
GCCGO="gccgo"
AR="ar"
CC="gcc"
CXX="g++"
CGO_ENABLED="1"
GOMOD=""
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build934234536=/tmp/go-build -gno-record-gcc-switches"

Conclusion

Simple eh? 👍

no get “go-ing” 😂
