Raspberry Pi Install golang

With the development of the Internet, people's demand for programming languages ​​is growing. One of the programming languages ​​that has attracted much attention is the Go language (also called Golang).

Golang is an open source, efficient static programming language developed by Google. Its goal is to provide a simple, fast, and efficient programming language suitable for modern computer hardware and systems, especially distributed systems and large-scale network programs.

For Raspberry Pi users, installing Golang allows you to write efficient and reliable programs on Raspberry Pi and optimize hardware resources. This article will introduce you how to install Golang on Raspberry Pi.

Step 1: Download Golang

To install Golang on the Raspberry Pi, you first need to download the corresponding binary file from the Golang official website (https://golang.org/dl/). Note that you need to download the version for ARM processors, not the X86 version.

You can download through the command line or use the Raspberry Pi's default browser. If you choose to use the command line, you can download Golang using the following command.

wget https://dl.google.com/go/go1.16.3.linux-armv6l.tar.gz

Step 2: Unzip and install Golang

After the download is complete, unzip the tar package:

tar -C /usr/local -xzf go1.16.3.linux-armv6l.tar.gz

Then add Golang to the PATH environment variable:

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

Use the following command to add export to the environment variable:

sudo nano /etc/profile

Add the following content at the bottom of the profile file:

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

Save the changes and exit the file. Now, you have successfully installed Golang.

Step 3: Test Installation

To test whether your installation is correct, you can use the following command to view the Golang version:

go version

If everything is fine, you will see Golang version information.

Step 4: Write Hello World program

Create a new folder through the following command

mkdir golang-tutorial && cd golang-tutorial

Run the following command to create a new file hello in the new folder .go:

nano hello.go

Write the following code in the file, save and exit:

package main

import "fmt"

func main() {
    fmt.Println("Hello World!")
}

Run the following command to compile and run the program you just wrote:

go run hello.go

You You will see the output "Hello World!"

Summary

In this article, we provided the steps to install Golang on Raspberry Pi and how to write a Hello World program and run it successfully. If you want to learn Golang in depth, we recommend reading it using the Golang official documentation (English) or Google Translate.

The Go language is widely used in cloud computing, containerization, distributed systems, big data, blockchain and other fields, and will receive more attention in the future. Therefore, learning and mastering Golang will lay a solid foundation for your future programming career.
