Devops关键工具及技术(五)—基于Pipeline的Bash脚本部署

在上一篇文章Devops关键工具及技术(四)—基于Pipeline的SonarQube静态代码扫描中，我们在持续集成的基础上加上了静态代码扫描，并利用Pipeline对之前Spring-boot的工程进行了代码扫描。并且在SonarQube中看到了代码中各个指标的一些信息。代码工程Github地址为:https://github.com/zbbkeepgoing/springboot-demo 。

接下来我们将会为Pipeline加上部署的Stage，部署采用sh脚本进行部署。后续我们将会采用Ansible的自动化部署。

Sh脚本

沿用之前的Spring-boot工程，经过持续集成后，我们将会得到maven构建后的一个jar包，这个jar即是工程的启动jar包。而我们需要把这个jar部署到另外一台机器上，实现从持续集成、代码静态扫描、以及部署的整个过程 。
首先我们看一下sh脚本的内容:

#!/bin/bash
id=$(ps -ef|grep sample.jar|grep -v grep|awk '{print $2}')   //查找出名称中sample.jar的进程
if [ ! $id ]; then echo "process not started"; else kill -9 $id;fi    //如果存在，则kill掉
sleep 2s;   //sleep 2秒
nohup java -jar /tmp/sample.jar  > nohup.out &   //java -jar 启动jar

Pipeline

我们继续沿用上一篇文章Devops关键工具及技术(四)—基于Pipeline的SonarQube静态代码扫描中的Pipeline，并在其后面加上部署的Stage。

                   sh 'sleep 8s'     //睡眠8s
