jenkins发布spring boot项目（附带发布+备份脚本)

1.安装jenkins
2.安装插件
3.配置jenkins maven项目发布流程
4.发布测试

1.安装，我们选择用docker版的（选用jenkinsci/blueocean)
docker search jenkinsci/blueocean

1.1 下载成功后启动，指定8080端口.
docker run -d -p 8081 --name jenkins docker.io/jenkinsci/blueocean

2.1 安装git、maven、jdk等工具插件

3.2 脚本截图
注意因为我们是docker启动的，所以脚本要放在docker里面

进入docker容器

脚本上部分

脚本下部分

脚本的主要内容是：
1.创建目录,分别是1./data(跟目录) 2./data/application/项目目录（存放项目jar的目录) 3./data/application_backup/项目目录 （存放备份项目jar的目录) 4./data/logs/项目目录 (存放日志记录的文件夹)
2.发布的时候先编译代码，然后备份jar包，关闭进程
3.发布项目
效果如图:

脚本：

username=root
