How to deploy script in golang

Golang is a very popular programming language that is widely used in fields such as network programming, microservices, and containerization. However, for beginners and non-experts, how to correctly deploy Golang applications may be a difficult task. Therefore, we need a convenient and simple deployment script to solve this problem.

This article will introduce how to use a simple Golang deployment script to automatically deploy Golang applications. Before starting, make sure you have installed the Golang environment and understand some basic Linux commands. Let’s get started now!

1. Create a deployment script

First, create a script file named deploy.sh and add the following content:

#!/bin/bash

# 指定应用名称
APP_NAME="your_app_name"

# 指定应用文件名称
APP_FILE="main.go"

# 指定运行端口
APP_PORT="8080"

# 编译应用
go build -o $APP_NAME $APP_FILE

# 后台运行应用
nohup ./$APP_NAME -port $APP_PORT > /dev/null 2>&1 &

In this In the script, we specify basic information such as the name of the application, the name of the application's entry file, the port number where the application runs, and so on. Next, we use the go build command to compile the application and the nohup command to run the application in the background. This ensures that the application keeps running on the server even after the script is executed.

2. Modify permissions

Under Linux system, we need to add execution permissions to the script. Change the script permissions using the following command:

chmod +x deploy.sh

3. Run the script

Next, we can run the deployment script. Use the following command to run the script:

./deploy.sh

This will automatically compile and run your app. You can now test whether your app has been successfully deployed by visiting $APP_SUM_HOST:$APP_PORT.

4. Customization

The above script is only based on the most basic Golang application scenario. If you need to customize your application, you can modify the deployment script as follows:

• Specify different application names, application file names and running ports.
• Add additional compilation or build process before deploying the server.
• Add other commands to the script, such as Git clone or update code, etc.

In general, this script can be used as the basis for deploying Golang applications, and can facilitate secondary development. I hope this article can help you complete the Golang application deployment task more easily.
