How to compile and install Golang

Golang is a modern programming language that is put into practical work by many programmers and developers. Golang is very simple to compile and install, and it can run on a variety of operating systems. This article will detail how to compile and install Golang.

1. Download Golang

First, you need to download the corresponding Golang binary code from the Golang official website (https://golang.org/dl/). In the download page, you need to select the appropriate package for your system. For example, if you are running a Linux system, you will need to download a .tar.gz file suitable for Linux.

2. Decompress Golang

After the download is complete, you need to decompress the file into the required directory. For example, you can extract the file to the /home/user directory. Open the terminal and use the following command:

tar -C /home/user -xzf go1.xx.x.linux-amd64.tar.gz

where go1.xx.x is Download the Golang version number.

3. Configure Golang environment variables

After decompressing Golang, you need to set some environment variables. For convenience, we choose to set these variables in the /etc/profile file. You need to open this file with a text editor:

sudo nano /etc/profile

Add the following line at the end of the file:

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

GOPATH is the default path of the Golang project. You can change the value of this variable according to your needs. The PATH variable allows you to run go commands directly. When you're done editing, save your changes and exit the text editor. To make the variables take effect, execute the following command:

source /etc/profile

4. Run the first Golang program

Now, Golang has been successfully installed and The corresponding environment variables are set. Let's write and run our first Golang program. Using a text editor (e.g. nano), create a hello.go file:

nano hello.go

Enter the following code:

package main

import "fmt"

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

Save and exit the editor. Now, build and run the program:

go build hello.go
./hello

If all goes well, you will see the "Hello, World!" message.

5. Summary

Now, you have learned how to download, unzip, configure environment variables and run Golang. As you continue to learn more about the Golang language, you will discover other useful Golang libraries and frameworks that will further improve your programming skills.
