How to install and configure the golang environment in Linux system

Step 1: Download and decompress the Golang installation package

First, we need to download the corresponding version from [Golang official website](https://golang.org/dl/) Golang installation package. Choose the appropriate version based on your operating system and processor architecture. Let's take the 64-bit Linux system as an example. Download the Golang installation package as follows:

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

After the download is complete, we need to decompress the installation package. The command to decompress the Golang installation package is as follows:

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

After decompression is completed, we can view the decompressed directory structure through the ls command, as follows:

drwxr-xr-x  9 root root 4.0K Oct  7 10:53 go

Step 2: Set environment variables

After Golang is decompressed, we need to configure environment variables. The so-called environment variables are values ​​defined in the operating system to save information about the system environment. For Golang, we need to configure two environment variables, GOPATH and GOROOT.

• GOROOT: Golang installation path, that is, the decompressed installation directory.

• GOPATH: Golang developer working directory.

We can open the ~/.bashrc file through the vim editor and add the following content:

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

Here we set GOROOT to /usr/local/go, and GOPATH is set to $HOME/go. Of course, these paths can be changed according to your own needs.

Note: If there is no go/bin directory locally, please create it manually.

After saving and exiting the ~/.bashrc file, we need to execute the following command to make the modifications effective:

source ~/.bashrc

Step 3: Verify whether Golang is installed successfully

Complete the second step After configuring the environment variables in this step, we can test by entering the following command:

go version

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

The following is a sample output:

go version go1.17.1 linux/amd64

Step 4: Write and run Golang code

After Golang is installed, we can happily start writing and running Golang code.

First, we need to create a directory to store our code files.

mkdir sample
cd sample

Next, we create a Golang source code file named main.go and edit it using the vim editor.

vim main.go

Enter the following content and save:

package main

import "fmt"

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

Finally, we run the above code through the go run command. The command is as follows:

go run main.go

After the operation is successful, the console outputs information As follows:

Hello, goland!
