【Jenkins】Linux下安装Jenkins并配置自动化部署Springboot的Git项目

准备工作：

安装Tomcat
安装Maven
安装Git
安装Jdk

Tomcat下Jenkins安装：

Jenkins的安装与设置

选择war包下载 http://my-tech.oss-cn-hangzhou.aliyuncs.com/jenkins.war

配置自动部署

新建工程-->构建一个Maven项目

源码管理选择Git,Repository URL填入Git仓库的地址

在Credentials添加自己Git仓库的账号名和密码，选择分支（默认master）

构建中Goals and options填入clean install

点击构建右下角的高级,选择使用自定义的工作空间，目录中填入你想打包的目录地址（到这一步打包就能完成了）。Settings file和Global Settings file填入maven的settings.xml地址

点击下面的add post-build step，选择execute shell，命令框中就是打包后执行的shell命令。

代码语言：javascript复制

source /etc/profile
#切换到打包的jar文件目录
cd /home/jenkinsWebApps/Blog/target
#移动jar文件到我的指定启动目录
mv my-blog-1.0.0-SNAPSHOT.jar /home/web/myblog
#切换到启动目录
cd /home/web/myblog
#执行脚本，重启项目
./start.sh restart
