通用程序部署shell脚本

简介

通常一个独立的服务,程序,中间件成后,为便于测试,上线部署都会编写一一个shell用于对程序的启动,重启 ,查看状态,停止,卸载 等动作, 以下是 一个使用shell脚本来实现的简单demo, 直接见代码。


功能

  1. 启动: start
  2. 重启: restart
  3. 停止:stop
  4. 卸载:uninstall
  5. 查看运行状态: status
  6. 获取程序版本号:version

代码

将代码中的 $YOUR_APP_NAME 替换成真实的程序文件名, shell文件名称: manager.sh

#!/bin/bash

mode=$1 # uninstall/start/restart/stop/status/version

使用

  1. 启动: sh manager.sh start

    # 输出效果如下
    [+] deploy the program ...
    [+] install done!
    
  2. 重启:sh manager.sh restart

    # 输出效果如下
    [+] stop $YOUR_APP_NAME ...
    [+] deploy the program ...
    [+] install done!
    [+] restart done!
    
  3. 停止: sh manager.sh stop

    # 输出如下
    [+] stop $YOUR_APP_NAME ...
    
  4. 卸载: sh manager.sh uninstall

  5. 查看版本号: sh manager.sh version

    #输出如下:
    XXX agent API service.
    The Version: 0.2.2
    
  6. 帮助手册: sh manager.sh --help

    # 输出如下
    gettext  $YOU_APP_NAME Deployment Management Script
    
    Usage:
      ./manager.sh [COMMAND]
      ./manager.sh --help
