Step One: Install Golang

First, you need to install Golang on your CentOS system. To install it, follow these steps:

  1. Open a terminal and download the Golang package using the following command: wget https://golang.org/dl/go1.15.3.linux-amd64 .tar.gz
  2. To decompress the downloaded file, use the following command: tar -C /usr/local -xzf go1.15.3.linux-amd64.tar.gz

3. Add Golang to the system environment variable and use the following command: echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.bashrc

4. Finally, use the following command to check whether Golang is installed correctly: go version

The above steps will help you successfully install Golang on your CentOS system. Next, you need to perform some important configuration steps to ensure that your Golang environment works properly.

Step 2: Configure Golang environment

Once you have installed Golang from the official website, the next step is to configure your Golang environment. To complete this process, please follow the steps below:

1. Set the GOPATH environment variable using the following command: echo "export GOPATH=$HOME/go" >> ~/.bashrc

3. Update GOPATH, use the following command: source ~/.bashrc

Now, you have completed the configuration process of the Golang environment. You can start developing your applications using the Golang programming language.

Step 3: Create your first program

Once you have installed and configured Golang, the next step is to start creating your first program.

In your terminal, create a new directory to store your application. Use the following commands to execute in sequence:

mkdir ~/myproject

cd ~/myproject

Create a file and use "hello.go" as the file name. Then, edit the file and add the following code:

package main

import "fmt"

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

Build and run your application by running the following command:

go build hello.go

./hello

You will output the "Hello World!" message to the console.
