How to install golang on ubuntu? (step sharing)

Golang is a modern programming language with powerful performance and efficient development tools. It is very suitable for developing cloud computing, network applications, distributed systems and other fields. Installing Golang on your Ubuntu system allows you to start developing immediately.

In this article, we will introduce the steps on how to install Golang on Ubuntu system. Below are the specific installation steps.

Step 1: Install Golang

First open the terminal and enter the following command:

sudo apt update
sudo apt install -y golang

This command will update and install Golang dependencies on Ubuntu item. After the installation is complete, you can check whether Golang is installed successfully by entering the following command in the terminal:

go version

If Golang is installed successfully, the information of the current Golang version will be displayed.

Step 2: Set GOPATH

Before using Golang, we need to set GOPATH. This variable is used to store the path of your Golang project. By default, GOPATH is located in the $HOME/go path.

To set GOPATH, follow these steps:

1. First, enter the following command in the terminal to open bash's configuration file.

   nano ~/.bashrc

2. Add the following to the end of the configuration file:

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

3. Save and close the file. Now we need to refresh bash's configuration files so they can reload. Execute the following command:

   source ~/.bashrc

Now that you have successfully set up your GOPATH, you can start using Golang!

Step 3: Create your first Golang application

Now that we have completed the installation and setup of Golang, we will create a simple Golang application "Hello World" application to test if it is working properly.

Open a text editor, enter the following code and save the file as "hello.go":

package main

import "fmt"

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

Now navigate the terminal to the directory where the hello.go file is saved and enter the following command: The

go run hello.go

command will compile and run your hello.go file and output "Hello World!". If you see this output, you have successfully installed and used Golang.

Summary:

Golang is a powerful programming language that is very easy to install and configure. By following the steps above to install Golang and running a simple "Hello World" application in your local environment, you have successfully verified the installation of Golang on your Ubuntu system. Next you can start developing more complex and powerful programs.
