篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了RPM开机自启+退出保活，再不担心java进程掉了~相关的知识，希望对你有一定的参考价值。
RPM简介
RPM的全名是Red Hat Package Manager，本意是Red Hat 软件包管理，顾名思义是Red Hat 贡献出来的软件包管理。
简单说，RPM就是将部署统一化，一键化。
RPM优点和缺点
- 优点
由于已经编译完成并且打包，所以安装很方便
由于套件信息已经记录在Linux主机的数据库中，方便查询、升级与卸载 - 缺点
安装环境必须与打包时的环境一致
需要满足软件的依赖属性需求
卸载时需要特别小心，最底层的软件不可以先删除，否则可能造成整个系统出问题
Java 打RPM包
maven 加rpm-maven-plugin插件

RPM 常用命令
rpm 基本命令
安装： rpm -ivh cloud-eyes-0.0.1-96e3ea5.noarch.rpm
升级： rpm -Uvh cloud-eyes-0.0.1-96e3ea5.noarch.rpm
查询已安装的rpm： rpm -qa cloud-eyes
查询某rpm详细信息：rpm -qpi cloud-eyes-0.0.1-094a474.noarch.rpm
卸载： sudo rpm -e cloud-eyes --allmatches --nodeps （强制卸载）
