Downloading Go Lang Installation Files

Visit Go Lang’s official download page to download the installer according to your operating system. See Downloads

Go Lang is currently supported only on x64 based processors.

Setting up on Windows

• Double click the MSI installer, you just downloaded to start the Go Lang installation on your Windows system.
• Follow the prompts to install the Go tools. By default, the installer puts the Go distribution in C:\Go.
• The installer should put the C:\Go\bin directory in your PATH environment variable. You may need to restart any open command prompts for the change to take effect.

Setting up on Linux

• Extract the .tar.gz archive you just downloaded to /usr/local, creating a Go tree in /usr/local/go.

$ sudo tar -C /usr/local -xzf go1.15.2.linux-amd64.tar.gz

Change the archive name as per requirement. go1.15.2.linux-amd64.tar.gz is the latest version available at the time of this writing.

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

$ export PATH=$PATH:/usr/local/go/bin

Verifying your installation

$ go version

• Create a file named main.go using the text editor of your choice, and copy-paste the following content into it.

package main

import "fmt"

func main() {
    fmt.Printf("Hello, World..!!\n")
}

• Save the file and go back to the terminal and run the following command to compile the code into a binary.

$ go build

• The previous step creates a binary named main in the same directory. Simply run the executable to run the code.
• If the installation had been correct, the exe will print Hello, World..!!
