golang deployment and installation video

Golang is a widely used programming language that excels in speed, functionality, and stability. If you want to learn Golang or use it in practical applications, you need to install and configure the Golang environment first. Next, this article will provide you with a golang deployment and installation video tutorial, and introduce you to how to quickly create, compile and run Golang projects.

1. Download Golang installation package
   First, you need to download a Golang installation package from the official website. Golang’s official website address is https://golang.org/. Open the official website, find the "Download Go" button, and click to enter the download page. On this page, installation packages for multiple operating systems are displayed. Please download the corresponding installation package according to your operating system and bit number.
2. Installation Golang
   After the download is complete, open the installation package and follow the prompts to install. The process is fairly intuitive, and environment variables can be set during the installation process to help you quickly use Golang in the terminal.
3. Configure Golang environment variables
   If the installation is successful, you need to set the environment variables so that you can quickly use Golang in the terminal. In macOS/Linux, you can set environment variables by executing the following command in the terminal:

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

where GOPATH is the environment variable used to store Golang projects and dependencies. During the process of specifying your GOPATH, it is recommended that you create a new directory to store your Golang project.

4. Create Golang Project
   Now that you have installed and configured the Golang environment, you need to create a Golang project. Creating a project is very simple, just create a new directory in the path specified by your GOPATH. For example, in macOS/Linux, you can execute the following command to create a new project:

$ mkdir $GOPATH/src/hello
$ cd $GOPATH/src/hello

In the above command, first use the mkdir command to create a new directory named hello, and use the cd command to switch to in this directory.

5. Writing Golang Code
   Now you can create a new Golang code file in the hello directory. For example, you can create a file named main.go in this directory and enter the following:

package main

import "fmt"

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

6. Compile and run the Golang project
   Now you are done To write a Golang project, you need to compile and run the project. In macOS/Linux, you can execute the following command in the terminal:

$ go build
$ ./hello

In the above command, first use the go build command to compile the project and generate an executable file named hello. Then, execute the ./hello command to start the executable.

7. Summary
   In this article, we showed you how to install and configure the Golang environment, and introduced how to create, compile and run Golang projects. Golang is an easy-to-learn programming language with excellent performance and scalability. If you start using Golang for project development, you can use the steps in this article to install the environment and write projects to quickly get started with Golang.
