Deploy spring boot project with jenkins

Jenkins 是什么？

Jenkins 是一个可扩展的持续集成引擎。

主要用于：

持续、自动地构建/测试软件项目。监控一些定时执行的任务。 Jenkins 拥有的特性包括：

易于安装-只要把jenkins.war部署到servlet容器，不需要数据库支持。
易于配置-所有配置都是通过其提供的web界面实现。
集成RSS/E-mail通过RSS发布构建结果或当构建完成时通过e-mail通知。
生成JUnit/TestNG测试报告。
分布式构建支持Jenkins能够让多台计算机一起构建/测试。
文件识别:Jenkins能够跟踪哪次构建生成哪些jar，哪次构建使用哪个版本的jar等。
插件支持:支持扩展插件，你可以开发适合自己团队使用的工具。

准备工作

环境

JDK:1.8  
Jenkins:2.138.3
Centos:7.3  

安装

下载

[zxb@server00 jenkins]$ pwd
/home/zxb/jenkins
[zxb@server00 jenkins]$ wget http://mirrors.jenkins.io/war-stable/latest/jenkins.war

启动

关闭防护墙

[zxb@server00 jenkins]$ systemctl stop firewalld.service

启动服务

[zxb@server00 jenkins]$ java -jar jenkins.war --httpPort=9090

Jenkins 就启动成功了！它的war包自带Jetty服务器

访问

浏览器访问：http://localhost:9090/

第一次启动Jenkins时，出于安全考虑，Jenkins会自动生成一个随机的按照口令。

注意控制台输出的口令，复制下来，然后在浏览器输入密码：

*************************************************************

Jenkins initial setup is required. An admin user has been created and a password                                                                                generated.
Please use the following password to proceed to installation:

部署脚本

把脚本放到 /etc/rc.d/init.d 下赋权限 chmod 777 spring-boot.sh

部署语法

enter description here

#!/bin/bash -l

mvn clean package

cp /etc/rc.d/init.d/spring-boot.sh /home/zxb/.jenkins/workspace/sayHelloProject/target

cd /home/zxb/.jenkins/workspace/sayHelloProject/target

./spring-boot.sh restart gs-rest-service-0.1.0.jar

请注意配置构建脚本的时候的写法,没有BUILD_ID=dontKillMe 是不可以的

BUILD_ID=dontKillMe nohup java -jar $SpringBoot > /dev/null 2>&1 &
