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
- 启动: start
- 重启: restart
- 停止:stop
- 卸载:uninstall
- 查看运行状态: status
- 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
