Let's talk about the methods and steps of Golang deployment program

Golang is a popular programming language popular for its efficiency, scalability and cross-platform nature. With the development of technology, more and more users have begun to develop Golang and need to deploy it to different environments. This article will introduce you to the methods and steps of Golang deployment program.

1. Preparation work

Before starting the Golang deployment program, we need to complete some preparation work. These tasks include:

1. Choose a cloud server

You can purchase cloud servers on the platforms of cloud service providers such as Alibaba Cloud and Tencent Cloud. When purchasing, pay attention to the server's operating system and hardware options. Please choose the server that suits your project.

2. Install the necessary software

Next, you need to install the necessary software on the server, including Golang, Git, etc. You can download and install using the following command:

sudo apt-get update
sudo apt-get install golang git

3. Confirm Golang version

After installing Golang, you need to confirm whether the version of Golang is correct. Enter the following command in the terminal:

go version

If the output is similar to "go version go1.13 linux/amd64" The result indicates that Golang has been installed correctly.

2. Create a Golang application

Next, you need to create a Golang application and upload it to the server. You can follow the steps below:

1. Create a Golang application

Create a new Golang application locally using the following command:

mkdir myapp
cd myapp
go mod init example.com/hello

These commands will create a new directory named myapp and create a Golang application named hello in it.

2. Writing Golang Code

Next, you need to open the main.go file using any text editor such as vim or nano and write some Golang code. Here is a simple example:

package main

import "fmt"

func main() {

fmt.Println("Hello, world!")

}

3. Testing the Golang application

In the command line, change the folder to the myapp folder and run the following command to make sure the program works properly:

go run .

If everything goes well, you will see the output of "Hello, world!" on the command line.

4. Upload code to the server

Finally, use Git to upload your program to the server. You can upload your project to the server using the following command:

git init
git add .
git commit -m "initial commit"
git remote add origin ssh://user@your -server-ip:/path/to/repository.git
git push -u origin master

These commands upload the project to a specific path on the server. Be sure to replace "user" with your username on the server, "your-server-ip" with your server's IP address, and "/path/to/repository.git" with your project path.

3. Deploy Golang application

Now, we can deploy the Golang application to the server. Here are the steps:

1. Clone the codebase on the server

First, you need to clone the codebase into a specific directory on the server using the following command:

git clone ssh://user@your-server-ip:/path/to/repository.git

This will create a new directory on the server to store your application code.

2. Build Golang Application

In your repository directory, use the following command to build your Golang application:

go build

This command will generate an executable file named "hello" in the current directory.

3. Running Golang Application

Finally, run your Golang application using the following command:

./hello

Above The command will launch your Golang application on the server and display the output of "Hello, world!" on the command line.

Conclusion

Golang is a powerful programming language that can be used to build high-performance web applications, network services, command line tools, etc. This article explains how to deploy a Golang application on a cloud server and shows you the steps of the entire process. Now you can easily deploy your Golang applications to any environment and enjoy the benefits of efficiency and scalability.
