Golang environment construction-Linux version

Go language is a very popular programming language in recent years. It was launched by Google and has been widely used in the development of web applications, cloud platforms and other fields. This article will introduce how to build a Golang development environment in a Linux environment.

1. Install Golang

1.1 In the Linux system, the installation of Golang can be completed through the following command:

sudo apt-get install golang

1.2 After the installation is completed, you can view it through the following command Golang version information:

go version

If the Golang version information is output, it means that Golang has been installed successfully.

2. Set up the Go language development environment

2.1 Create a working directory

You can create a working directory named "go_project" through the following command:

mkdir go_project

2.2 Set GOPATH

GOPATH is an environment variable that specifies the working path. You can use the following command to set GOPATH:

export GOPATH=$HOME/go_project

It should be noted that the GOPATH environment variable is only temporarily set here. If you want to set the environment variable permanently, you can set it in the .bashrc file.

2.3 Create a source code directory in the working directory

In the previous step, we have created a working directory named "go_project". In this directory, use the following command to create Source code directory:

mkdir src

2.4 Writing the Hello World program

At this point, we have completed the installation of Golang and set up the development environment. Next, we can start writing the first Golang program - Hello World.

In the src directory, create a file named hello.go and write the following code into the file:

package main

import "fmt"

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

2.5 Compile and run the Hello World program

Use the following command to compile and run the Hello World program:

go run hello.go

If everything goes well, the "Hello, world!" message will be output.

3. Debugging of Golang development environment

3.1 Debugging using Goland

Goland is a Go language IDE developed by JetBrains. When writing large Golang projects, it is recommended to use Goland for debugging.

In Goland, the following settings are required for debugging:

① Open Goland and select File -> Settings -> Go -> Build tags and Vendoring;

② Check the "Enable Go Modules integration" option;

③ Add the debug tag "debug" in "Build tags".

After adding the tag, you can start debugging Golang.

4. Summary

This article introduces how to build a Golang development environment in a Linux environment, covering installing Golang, setting up the development environment, writing and debugging Golang programs, etc.

In actual development, you need to master more Golang development knowledge to better complete the project. I hope this article will be helpful to everyone learning Golang development.
