2. Download the source code package

You can download the latest from the Golang official website https://golang.org/dl/ Golang source code package. Select the operating system and architecture you require and click the download button. In addition, you can also use the command line to download the source code package and decompress it:

$ curl -O https://storage.googleapis.com/golang/go1.17.1.linux-amd64.tar.gz
$ tar xvf go1.17.1.linux-amd64.tar.gz

4. Test installation

After completing the above steps, you can run the following command to test whether Golang is successfully installed:

$ go version

If the version number of Golang is output , the installation is successful. In addition, you can also create a simple helloworld.go program to verify the compilation and running of Golang:

package main

import "fmt"

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

Save the above program as a helloworld.go file, and then run the following commands to compile and run:

$ go build helloworld.go
$ ./helloworld

If Hello, world! is output, it means the compilation and operation are successful.
