RPM是什么？
RPM 是在 Linux 下广泛使用的软件包管理器，由 Red Hat 开发。它的全称是 RPM Package Manager，和 PHP、GNU 一样，是一个递归的缩写。RPM 软件包后缀名是.rpm。
依赖环境
打包需要在Linux上打包，并且需要以下前置依赖
yum install -y rpm-build rpmdevtools
RPM目录说明
- BUILD：源代码解压以后放的位置，只需提供BUILD目录，具体里面放什么，不用我们管，所以真正的制作车间是BUILD目录。
- BUILDROOT：假根，使用install临时安装到这个目录，把这个目录当作根来用的，所以在这个目录下的目录文件，才是真正的目录文件。当打包完成后，在清理阶段，这个目录将被删除。
- RPMS：制作完成后的rpm包存放目录，为特定平台指定子目录（i386,i686,ppc）。
- SOURCES：收集的源文件，源材料，补丁文件等存放位置。
- SPECS：存放spec文件，作为制作rpm包的领岗文件，文件以.spec结尾。
- SRPMS：src格式的rpm包位置 ，既然是src格式的包，就没有平台的概念了
SpringBoot构建RPM
目录结构
添加插件
使用 maven-jar-plugin + maven-assembly-plugin + rpm-maven-plugin三个插件打包构建
maven-jar-plugin：打包工程成为可执行jar包
maven-assembly-plugin： 使配置文件、启动脚本、依赖包分离，便于增量更新
rpm-maven-plugin： 生成构建RPM安装包
pom.xml文件内容如下：

添加开机自启相关配置
注册开机自启相关配置文件，放于src/main/rpm目录下
postinst 后置脚本
# !/bin/bash
/usr/bin/chmod +x ${rpm.install.location}/bin/*
/bin/systemctl preset ${project.name}
/bin/systemctl daemon-reload
/bin/systemctl --force enable ${project.name}
setup.service配置文件
[Unit]

打包命令
在Linux上使用命令mvn clean install -D rpm.plugin.phase=package 打包，生成的RPM安装包在目录target/rpm目录下
