Linux installation golang environment

With the continuous development of the Internet, artificial intelligence and other fields, programming languages ​​​​are also updated with each passing day, and Go is one of them. Go is an open source programming language developed by Google. It is efficient, stable, and concise, and has been welcomed by many programmers.

This article will introduce the detailed steps to install the golang environment under the Linux system, helping beginners quickly master the installation method of the golang environment.

1. Download golang

First, select the version suitable for your system on the golang official website https://golang.org/dl/ and download the corresponding installation package. Here we take the Linux system as an example and download the installation package of golang1.17 version.

You can use the following command to download the installation package:

wget https://golang.org/dl/go1.17.linux-amd64.tar.gz

2. Extract the installation package

After the download is complete, use the following command to decompress the installation package:

tar -C /usr/local -xzf go1.17.linux-amd64.tar.gz

After decompression, you can see that the go folder appears in the /usr/local directory.

3. Configure environment variables

Next, configure the environment variables into the system. Open the terminal and enter the following command:

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

After executing the above command, golang is installed.

4. Verify installation

To verify whether the installation is successful, execute the following command:

go version

If the installation is successful, the following information will be output in the terminal:

go version go1.17 linux/amd64

At this point, the golang environment has been successfully installed.

5. Configuring GOPATH

When we use go for project development, we need to set GOPATH. Enter the following command in the terminal:

mkdir $HOME/go

A folder named go will be created in the home directory.

Then open the terminal and configure the GOPATH environment variable:

export GOPATH=$HOME/go

Description: The Go language layout has a strict convention, that is, source code, executable files and other auxiliary files (such as existing Unix-like sockets or FIFOs) organized into a directory hierarchy called a workspace. By default, the workspace is the directory where the Go source code is installed, called GOROOT, but it can be changed by setting the environment variable GOPATH if necessary.

6. New project

Next, we can create a new project to test whether golang is configured successfully. Open the terminal and execute the following command:

mkdir $HOME/go/src/test

Create a file named main.go in the test directory:

cd $HOME/go/src/test
touch main.go

Enter the following code in the main.go file:

package main

import "fmt"

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

Execute the following command to compile and run the program:

go run main.go

If the following content is output, the program has run successfully:

Hello, world.

At this point, we have successfully installed golang under the Linux system through the above steps. environment.

Summary:

This article introduces the detailed steps for installing golang environment under Linux system, including downloading golang, decompressing the installation package, configuring environment variables, verifying the installation, configuring GOPATH, and creating a new test project. A few steps, hopefully helpful to beginners.
