有时候为了方便源码包的安装，我们需要自己订制软件包的需求，我们会把一些源码包按照我们的需求来做成rpm包，当有了源码包就可以直接编译得到二 进制安装包和其他任意包。spec file是制作rpm包最核心的部分，rpm包的制作就是根据spec file来实现的。下面是我以制作php的rpm开始介绍其制作方法。以下操作在CentOS6.6 64位系统进行。
下面我们以制作php的rpm开始介绍其制作方法。以下操作在CentOS6.6 64位系统进行。
[root@linuxeye.com SOURCES]# yum -y install rpm-build
[root@linuxeye.com SOURCES]# vim ~/.rpmmacros %_topdir /root/rpmbuild
[root@linuxeye.com SOURCES]# mkdir -pv ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
在redhat下，rpm包的默认制作路径在/usr/src/redhat下,但CentOS并没有该目录，因此，我们不得不自定义工作目录，这其中包含了6个目录（要求全部大写）
BUILD：源代码解压以后放的位置RPMS：制作完成后的rpm包存放目录，为特定平台指定子目录（x86_64）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，以rpm名.specSRPMS：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 BuiltRoot：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
[root@linuxeye.com SOURCES]# rpmbuild --showrc | grep topdir #工作车间目录：_topdir /root/rpmbuild-14: _builddir %{_topdir}/BUILD-14: _buildrootdir %{_topdir}/BUILDROOT-14: _rpmdir %{_topdir}/RPMS-14: _sourcedir %{_topdir}/SOURCES-14: _specdir %{_topdir}/SPECS-14: _srcrpmdir %{_topdir}/SRPMS-14: _topdir /root/rpmbuildrpmbuild –showrc显示所有的宏，以下划线开头，一个下划线：定义环境的使用情况，二个下划线：通常定义的是命令，为什么要定义宏，因为不同的系统，命令的存放位置可能不同，所以通过宏的定义找到命令的真正存放位置
