Golang environment deployment: Detailed explanation of correct configuration steps

In today's software development field, Golang (also known as Go language) is favored by developers as a fast and efficient programming language. In order to develop Golang correctly, you first need to correctly configure the Golang development environment. The following will introduce in detail how to deploy and install the Golang environment.

1. Download the Golang installation package

First, visit the Golang official website https://golang.org/ to download the Golang installation package suitable for your operating system, Golang Supported operating systems include Linux, Windows and macOS.

2. Install Golang

After the download is completed, select the appropriate installation method according to your operating system. Here we take installing Golang under Linux system as an example. After the download is completed, open the terminal and execute the following command:

tar -C /usr/local -xzf go$VERSION.$OS-$ARCH.tar.gz
export PATH=$PATH:/usr/local/go/bin

In the above command, $VERSION is the Golang version number you downloaded, and $OS is your operation system, $ARCH is your processor architecture. After executing the above command, the installation of Golang can be completed.

3. Configure Golang environment variables

In order to use Golang conveniently, you need to configure Golang environment variables. Run the following command in the terminal:

echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.bashrc
source ~/.bashrc

The above command adds Golang’s bin directory to the system’s environment variables, allowing you to run Golang commands directly in the terminal.

4. Verify Golang installation

After completing the above steps, you can verify whether Golang is successfully installed by entering the following command in the terminal:

go version

If the Golang version information is successfully output in the terminal, it means that Golang has been successfully installed and configured.

5. Write the first Golang program

Next, let’s write a simple Golang program to verify whether the environment configuration is correct. Create a file named hello.go in your favorite editor with the following content:

package main

import "fmt"

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

After saving the file, execute the following command in the terminal to run the program:

go run hello.go

If If "Hello, Golang!" is successfully output in the terminal, it means that your Golang environment has been configured correctly and the Golang program can run smoothly.

Through the above steps, you have successfully configured the Golang development environment and can now start using Golang for development. I hope this article will be helpful to you and help you start your Golang programming journey smoothly!
