Intranet deployment golang

Within the enterprise, in order to ensure data security, many companies will choose to build their own intranet environment. As a very popular programming language now, golang also needs to be deployed within the enterprise's intranet to ensure data security. In this article, we will introduce how to deploy the golang environment and perform golang programming in the corporate intranet environment.

1. Preparation

Before we start, we need to understand some basic knowledge:

• Go language source code and compiler download address: https: //golang.org/dl/
• The operating system is CentOS

In this article, we will use CentOS as our operating system and install the golang environment in CentOS.

2. Install golang

Step 1: Install wget and tar tools

In order to download the golang source code, we need to install wget and tar tools and execute the following commands:

$ sudo yum install wget tar -y

Step 2: Download golang source code

We can download the latest golang source code package from the official website. Here we take version 1.16.3 as an example:

$ wget https://golang.org/dl/go1.16.3.linux-amd64.tar.gz

Step 3: Decompress

We will decompress the downloaded golang source code package:

$ sudo tar -C /usr/local -xzf go1.16.3.linux-amd64.tar.gz

Step 4: Add environment variables for golang

In order to be in any directory You can use the golang environment. We need to add the golang environment to the environment variable and execute the following command:

$ sudo vi /etc/profile

Add the following code at the bottom of the file:

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

Then use the following command to make it effective:

$ source /etc/profile

Step 5: Check whether the golang environment is installed successfully

We can check whether the golang environment is installed successfully by running the following command:

$ go version

If the environment is installed successfully, The following information will be output:

go version go1.16.3 linux/amd64

3. Develop the first golang application

Below we will use a simple Hello World application as an example to develop the first golang application.

Step One: Create Files

We can use the following command in the command line to create a new .gofiles:

$ vi hello_world.go

Add the following in the hello_world.go file Code:

package main

import "fmt"

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

Step 2: Compile and run

We can use the following command to compile and run the program:

$ go run hello_world.go

When we execute the above command, the output will be as follows Information:

Hello, World!

4. Summary

This article introduces how to install the golang environment and develop the first golang application in the corporate intranet environment. Through the steps in this article, you can easily deploy the golang environment in your private network and start programming with golang.
