Analysis of steps to install golang in Ubuntu

Detailed explanation of the steps to install golang in Ubuntu system, specific code examples are required

Golang (also known as Go) is a modern programming language with efficient Concurrency performance and easy-to-use syntax are widely used to develop high-performance and reliable applications. Installing Golang on Ubuntu operating system is very easy and requires only a few simple steps.

Step 1: Download the Golang installation package
First, we need to download the Golang installation package corresponding to the Ubuntu version from the Golang official website. It can be downloaded in the terminal through the following command:

wget https://golang.org/dl/go1.17.2.linux-amd64.tar.gz

Please note that the link in the above command may change as the Golang version is upgraded, so please visit the Golang official website to confirm the download link for the latest version.

Step 2: Install Golang
After the download is completed, we need to extract the downloaded installation package to the appropriate directory. Run the following command in the terminal:

sudo tar -C /usr/local -xzf go1.17.2.linux-amd64.tar.gz

The above command will install Golang to the /usr/local directory. Make sure this directory is in the system environment variable.

Step 3: Configure environment variables
In order to use Golang in any terminal, we need to add the Golang binary file path to the system environment variables. Open the terminal and execute the following command:

echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.bashrc
source ~/.bashrc

The above command will add Golang’s binary file path to the user’s .bashrc file and reload it through the source command .bashrc file.

Step 4: Verify installation
After the installation is complete, we can verify whether Golang is installed correctly by running the following command in the terminal:

go version

If the command output is similar to go version go1.17.2 linux/amd64, it means the installation is successful.

Step 5: Write a Hello World program
Finally, we can write a simple Hello World program to verify the Golang operating environment. Create a new file hello.go and copy the following code into the file:

package main

import "fmt"

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

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

go run hello.go

You will see the output Hello, World! in the terminal.

Installing and configuring Golang in Ubuntu system is so simple. By following the steps above, you can successfully install Golang and start developing your applications using this powerful programming language.
