Detailed steps to install golang on Ubuntu, specific code examples are required

In recent years, the Go language (also known as Golang) has become increasingly popular in the development field . Its concise syntax, efficient concurrency support and cross-platform features make Go language the programming language of choice for many developers. In this article, we will detail the steps to install Golang on Ubuntu systems and provide relevant code examples.

Step One: Preparation

Before starting the installation, we need to ensure that the operating system is Ubuntu and is under the root user or a user with sudo permissions.

Step 2: Download the Golang installation package

We can download the Golang installation package suitable for Ubuntu on the Golang official website (https://golang.org/dl/).

For example, we download the latest version of Golang 1.17.1:

wget https://golang.org/dl/go1.17.1.linux-amd64.tar.gz

After the download is completed, we can decompress the installation package through the following command:

tar -xvf go1.17.1.linux-amd64.tar.gz

Step 3: Configure environment variables

In order to use the Go language, we need to add the Golang binary file path to the system's PATH environment variable. Edit the ~/.profile or ~/.bashrc file and add the following content:

export PATH=$PATH:/path/to/go/bin

Note: /path/to/ go should extract the full path to the installation package for you.

After saving and exiting the editor, run the following command to make it effective:

source ~/.profile

Step 4: Verify the installation

Installation After completion, we can verify the installation of the Go language by running the following command:

go version

If the version number of the Go language is displayed in the output information, the installation is successful.

Step 5: Write a Hello World program

Next, we will write a simple Hello World program to ensure that we can successfully compile and run the Go language program.

First, create a file named hello.go in any directory, and use a text editor to open the file:

nano hello.go

Then, add the following Paste the code into the hello.go file:

package main

import "fmt"

func main() {

fmt.Println("Hello, World!")

}

Save and exit the editor.

Step 6: Compile and run the program

In the command line, we can use the following command to compile and run hello.go:

go build hello.go
./hello

The output will be:

Hello, World!

Congratulations! You have successfully installed and run Golang.

Conclusion

Through the above steps, we can successfully install and configure Golang on the Ubuntu system, and write and run simple Go language programs. The simplicity and efficiency of the Go language make it one of the preferred languages ​​for developers. I hope this article can help you get started with Golang smoothly and enjoy the joy and convenience of development!
