Detailed explanation of how to install Go language on Linux system

Installing the Go language on a Linux system is very simple and only requires a few simple steps. Go language is an open source programming language developed by Google and is widely used in cloud computing and big data fields. Installing the Go language on a Linux system will provide developers with more choices and flexibility. This article will introduce in detail how to install the Go language on a Linux system and provide specific code examples.

Step 1: Download the Go language installation package

First, we need to download the Go language installation package. You can download the latest version of the Go language installation package from the official website, or you can use the package management tool to install it. Taking the Ubuntu system as an example, use the following command to download the installation package:

wget https://dl.google.com/go/go1.16.3.linux-amd64.tar.gz

Step 2: Decompress the installation package

After the download is complete, decompress the installation package to the specified installation directory. You can choose to extract the installation package to the system's /usr/local directory, or you can choose another custom directory. The decompression command is as follows:

sudo tar -C /usr/local -xzf go1.16.3.linux-amd64.tar.gz

Step 3: Configure environment variables

Next, we need to configure the environment variables of the Go language so that the system can correctly recognize and use the Go language. Open the terminal, edit the ~/.bashrc file, and add the following content at the end of the file:

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

After saving the file, run the following command to make the environment variables take effect:

source ~/.bashrc

Step 4: Verify the installation

After completing the above steps, we can verify whether the Go language is successfully installed through the command line. Enter the following command in the terminal:

go version

If the version information of the Go language is displayed, it means that the Go language has been successfully installed on the system.

Step 5: Write and run a simple Go program

Finally, we can write a simple Go program and run it to verify that the Go language development environment has been set up successfully. Create a file named hello.go and enter the following code:

package main

import "fmt"

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

After saving the file, run the following command in the terminal to compile and execute the program:

go run hello.go

If the console output "Hello, Go!" means that the program runs successfully and the installation and configuration of the Go language are completed.

Through the above steps, we successfully installed and configured the Go language development environment on the Linux system, and verified it with a simple sample program. Now, you can happily start developing projects using Go language!
