Jenkins

介绍

Jenkins是一个开源的、可扩展的持续集成、交付、部署（软件/代码的编译、打包、部署）的基于web界面的平台。允许持续集成和持续交付项目，无论用的是什么平台，可以处理任何类型的构建或持续集成。

官网：https://jenkins.io/ 官方文档：https://jenkins.io/doc/

特性

开源的java语言开发持续集成工具，支持CI，CD；

易于安装部署配置：可通过yum安装,或下载war包以及通过docker容器等快速实现安装部署，可方便web界面配置管理；

消息通知及测试报告：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；

丰富的插件支持:支持扩展插件，你可以开发适合自己团队使用的工具，如git，svn，maven，docker等。

jenkins功能：打包发布 jenkins是流程化工具

打包工具：

• gradler
• ant
• maven
• 打包工具版本必须一致

部署

关闭防火墙selinux
[root@localhost ~]# systemctl disable --now firewalld.service 
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost ~]# vim /etc/selinux/config 
[root@localhost ~]# setenforce 0
[root@localhost ~]# getenforce 
Disabled

安装openjdk、jenkins、tomcat
