Step 1: Download Latest Go Binary

At the time of this writing the latest available version is go1.13 . You can check for the latest version and get the download link from the official golang website.

Run the following command to download go using wget.

wget https://dl.google.com/go/go1.13.4.linux-amd64.tar.gz

Step 2: Install Go Language

Extract the downloaded archive it into /usr/local, creating a Go tree in /usr/local/go.

sudo tar -C /usr/local -xzf go1.13.4.linux-amd64.tar.gz

Add /usr/local/go/bin to the PATH environment variable by adding this line to your /etc/profile (for a system-wide installation) or $HOME/.profile for the current user installation.

Activate the environment variable to the current shell session using the following command.

source ~/.profile

Verify the installation using the following command.

go version
Output
go version go1.13.4 linux/amd64

This confirms Go language is installed in your server or system.

Step:3 Testing the Installation

Create your workspace directory, $HOME/go. (If you’d like to use a different directory, you will need to set the GOPATH environment variable.)

mkdir ~/go

Inside the go directory create these src/hello directories.

mkdir -p ~/go/src/hello

Now create a new file inside the hello directory with the name hello.go

nano  ~/go/src/hello/hello.go

Add these lines of code to the file.

package main

import "fmt"

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

Now move inside the hello directory and build the code using the go tool.

cd ~/go/src/hello
go build

This command will create a new executable in the current directory named as hello

Now execute the file to see the output.

./hello

Output
hello, world

Conclusion

Now you have installed and configured Go language and tested the installation by creating a new Go program which outputs Hello World.
