rpm生成安装包相关知识点
一. 查询rpm当前构建路径
rpm --showrc|grep _topdir二. 修改rpm的构建路径
我们可以通过修改topdir宏的值来自定义打包路径：
$ echo %_topdir $HOME/rpmbuild > ~/.rpmmacros //eg:echo %_topdir %{_usrsrc}/redhat > ~/.rpmmacros 将构建路径还原成默认构建路径。
三. 编译.spec文件时，提示错误“Installed (but unpackaged) file(s) found:”
错误原因：必须使用正确的相对路径，否则编译时提示“Installed (but unpackaged) file(s) found:”
四.spec文件编写
