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:2.83
Centos:7.3 安装
下载
cd /opt
wget http://mirrors.jenkins.io/war/2.83/jenkins.war启动
关闭防护墙
systemctl stop firewalld.service启动服务
java -jar jenkins.warJenkins 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:8080/
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：

*************************************************************进入用户自定义插件界面，建议选择安装官方推荐插件，因为安装后自己也得安装:
接下来是进入插件安装进度界面:
配置用户名密码:
初始化成功后进入 Jenkins 首页:
全局工具配置.Jdk,Mavem,git Docker,等配置，安装
构建项目
新建项目
这里，选择构建一个自由风格的软件项目；
源码管理
Jenkins支持多种源码管理服务器；
构建配置
选择 Execute shell 构建 输入一下命令并且保存
mvn clean package
立即构建
