前言：
RPM包安装快速、方便。使用源码包可以定制想要的功能，然后将其制作成.rpm格式的包。在生产环境中，我们的开发人员通常下载好源码包，选择好自己所需功能，丢给运维人员制作rpm包后。将其丢入本地yum源库，以后直接调用安装。。。
下面我们以apache WEB源码包httpd-2.2.25.tar.gz为例，来制作RPM包。

%configure 编译安装的流程
./configure --prefix=/usr/local/httpd --enable-cgi --enable-rewrite --enable-charset-lite --enable-so
make %{?_smp_mflags}
%install
rm -rf %{buildroot}
make install DESTDIR=%{buildroot}
%clean
rm -rf %{buildroot}
%files
%defattr(-,root,root,-) 这个包括了安装完成源码包，会在目标目录生成的文件，之前要先安 装一遍！

[[email protected] ~]$ rpmbuild httpd.spec 会提示失败，ls一下，会多出一个rpmbuild目录
[[email protected] ~]$ cd rpmbuild
[[email protected] ~]$ cp ../httpd-2.2.25.tar.gz SOURCES/
[[email protected] ~]$ cp ../httpd.spec SPEC/
[[email protected] ~]$ cd SPEC
[[email protected] ~]$ rpmbuild httpd.spec
[[email protected] ~]$接下来会进行编译安装及制作过程，制作完毕后，会在RPMS目录生成RPM包
[[email protected] x86_64]# pwd
/home/tom/rpmbuild/RPMS/x86_64
[[email protected] x86_64]# ls
