Background

Let us avail the go runtime on our system.

 

Lineage

1. OS
   • Microsoft – MS Windows
     Link

 

Linux

Though my primary OS is MS Windows, I play around a bit with Linux, as well.

Options

There are a couple of options for availing go on a Linux system.

The options include:-

1. rpm
   • Repositories
     • okey
       • Web Site
         https://centos.pkgs.org/7/okey-x86_64/golang-1.5.1-0.el7.centos.x86_64.rpm.html ( link )
2. tar.gz

We will go with fetching the tar from golang.

Outline

1. Artifact
   • Identify Artifacts Source
   • Determine appropriate artifact
2. Get Artifact
3. Install or Avail Artifact
4. Configure System

Determine Appropriate Artifact

Matrix

Here are the choices for a Linux Machine:-

Package OS Bitness go1.15.linux-386.tar.gz x86 32-bit go1.15.linux-amd64.tar.gz x86-64 64-bit go1.15.linux-arm64.tar.gz ARMv8 64-bit go1.15.linux-armv6l.tar.gz ARMv6 32-bit

 

Choice

We are running 64-bit Linux on an Intel/AMD Architecture.

And, so we will go with go1.15.linux-amd64.tar.gz.

 

Get Artifact

There are a couple of choices to download a file from a web server ( HTTP).

Choices

1. wget

 

wget

Syntax

wget

Sample

wget --no-check-certificate -O /tmp/go1.15.linux-amd64.tar.gz https://golang.org/dl/go1.15.linux-amd64.tar.gz

Install or Avail Artifact

There are a couple of choices to install or avail files on Linux.

Choices

1. Installer
   • rpm
2. Extract Package
   • Extraction Tools
     • tar

 

Installer

rpm

1. It seems that golang does not have an rpm file for Linux Installation.

Extract Package

Extraction Tool

tar

Syntax

sudo tar

Sample

sudo tar -C /usr/local -v -xzf go1.15.linux-amd64.tar.gz

 

Output

Output – Text

Configure System

Outline

1. Boundary
   • Entire System ( /etc/profile )
   • Self ( $HOME/.profile )
2. Elements
   • Path
3. Changes
   • OS – CentOS

Boundary

Decide on the boundary of what should be configured or affected.

If the entire system, please use ( /etc/profile ).

On the other hand, if you alone, ( $HOME/.profile ).

Elements

Here are the items that we will be configuring:-

1. Path

 

Changes

System – /etc/profile

Outline

1. Add a file to the /etc/profile.d folder
2. The file should add /usr/local/go/bin to the system’s path
   • export PATH=$PATH:/usr/local/go/bin
3. Execute Added File
   • source <file>

Add File to /etc/profile.d Folder

In our case, we will name the file ( /etc/profile.d/golangInstallSelf.sh ).

File Contents

>sudo cat /etc/profile.d/golangInstallSelf.sh
[sudo] password for dadeniji:
export PATH=$PATH:/usr/local/go/bin
>

 

Execute Loaded File

source <file>

Image

Validate

To validate installation:-

System ( /etc/profile )

1. Initiate go

 

Syntax

go version

Sample

go version

Output

Output – Image

Output – Text

>go version
go version go1.15 linux/amd64
