Integration of Vue.js and Shell scripts, tips and suggestions to simplify system management and automated deployment

Introduction:
With the development of cloud computing and container technology, system management and automated deployment have become more and more important. Vue.js is a popular JavaScript framework that makes it easy to build user interfaces and single-page applications. Shell script is a scripting language used for system management and automation tasks. This article will introduce how to integrate Vue.js with Shell scripts to simplify the process of system management and automated deployment, and provide some tips and suggestions.

1. Why integrate Vue.js and Shell script?
In actual system management and automated deployment, a series of tasks are often required, such as compiling and packaging code, configuring and modifying files, executing commands and scripts, etc. Vue.js provides a convenient component-based development method that can well separate the front-end interface and logic from the back-end tasks and scripts. At the same time, Shell script, as a powerful system management tool, can complete different tasks, such as deploying applications, configuring servers, etc. Therefore, integrating Vue.js and Shell scripts can make system management and automated deployment more efficient and easier.

2. How to integrate Vue.js and Shell script?

1. Create Vue.js project:
   First, we need to create a Vue.js project, which can be quickly created using Vue CLI. Execute the following command in the terminal:

   $ npm install -g @vue/cli
   $ vue create my-project

   Copy after login

2. Install the Shell script running environment:
   In order to call the Shell script through Vue.js, we need to install some necessary dependencies. Execute the following command in the terminal:

   $ npm install shelljs

   Copy after login

3. Write Vue.js code:
   In a certain component in the Vue.js project, we can introduce and call the Shell script. For example, we create a "RunShell" component and write the following code in the component:

   <template>
     <div>
    <button @click="runShellScript">执行Shell脚本</button>
     </div>
   </template>
   
   <script>
   import shell from 'shelljs';
   
   export default {
     methods: {
    runShellScript() {
      shell.exec('sh deploy.sh');
    }
     }
   }
   </script>

   Copy after login

   In the above code, when the button is clicked, the runShellScript method will be called, and the execution name is ## Shell script of #deploy.sh.

4. Write a Shell script:

   Create a file named
   deploy.sh in the project root directory and write the Shell script code that needs to be executed. For example, the following is a simple sample script:

   #!/bin/bash
   
   echo "开始部署应用程序"
   
   # 拉取最新代码
   git pull origin master
   
   # 安装依赖
   npm install
   
   # 编译打包
   npm run build
   
   # 启动应用程序
   pm2 restart app.js
   
   echo "应用程序部署完成"

   Copy after login
   The above script will execute a series of commands, such as pulling the latest code, installing dependencies, compiling and packaging, and starting the application.

Use SSH keys for remote execution:
1. If you need to execute a Shell script on a remote server, you can use SSH Secret key for authentication and connection. This avoids the need to enter a password every time it is executed and improves execution efficiency.
   
Parameterized script:
2. In order to make the Shell script more versatile and flexible, some parameters can be extracted into configurations and passed to the script through parameters. For example, the server address, application name, etc. can be passed as parameters to the script and dynamically configured during execution.
   
Log and error handling:
3. In the Shell script, the output can be saved to the log file through redirection to view the execution results and error information. At the same time, error handling and exception capture can be performed during the execution process through
   if statements and conditional judgments.

By integrating Vue.js and Shell scripts, the process of system management and automated deployment can be simplified. This article introduces how to create a Vue.js project, install the Shell script running environment, write Vue.js code and Shell scripts, and provides some tips and suggestions. I hope readers can use the guidance of this article to better utilize Vue.js and Shell scripts for system management and automated deployment.
