Linux之shell脚本实现java服务的一键启动停止重启及每个服务单独的重启

时间：2020-05-12 18:32:46

shell脚本提供了一键启动、停止、重启及每个服务单独的重启的函数。

脚本实现了：

调用sh文件根据不同的入参调用不同的函数创建文件夹创建文件自定义函数调用自定义函数（调用函数时传入参数）调用jar包运行（设置占用内存）

一、创建shell文件

二、编写代码

三、linux终端运行脚本

1、查看服务运行状态

2、一键启动

3、一键停止

4、一键重启

5、单个服务重启（以message服务为例）

微服务架构下，服务比较多。每次安装部署的时候，一个个启动很麻烦。编写脚本实现服务的一键启动、停止、重启及每个服务单独的重启，以简化安装部署工作。

步骤：

一、创建shell文件

创建一个文本文件，重命名为：philicube_start.sh

二、编写代码

总体代码如下：
