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。
[root@localhost ~]# ls
anaconda-ks.cfg httpd-2.2.25.tar.gz
[root@localhost ~]# yum -y install rpm-build gcc gcc-c++
[root@localhost ~]# useradd tom
[root@localhost ~]# cp httpd-2.2.25.tar.gz /home/tom/
[root@localhost ~]# su - tom
[root@localhost Packages]# rpm -qpi httpd-2.2.15-29.el6_4.x86_64.rpm

web server.
//上面我们可以看到系统自带的httpd软件包的详细信息。。
[root@localhost ~]$ vim httpd.spec 此时我们以普通用户编辑一个文件，一定要以.spec结尾

%prep
%setup -q
%build
%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！
/usr/local/httpd/bin/*
/usr/local/httpd/build/*
/usr/local/httpd/cgi-bin/*
%config /usr/local/httpd/conf/* %config %dir %doc 按如下格式写
/usr/local/httpd/error/*

%dir /usr/local/httpd/logs

[root@localhost ~]$ rpmbuild httpd.spec 会提示失败，ls一下，会多出一个rpmbuild目录
[root@localhost ~]$ cd rpmbuild
[root@localhost ~]$ cp ../httpd-2.2.25.tar.gz SOURCES/
[root@localhost ~]$ cp ../httpd.spec SPEC/
[root@localhost ~]$ cd SPEC
[root@localhost ~]$ rpmbuild httpd.spec
[root@localhost ~]$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
[root@localhost x86_64]# pwd
/home/tom/rpmbuild/RPMS/x86_64
[root@localhost x86_64]# ls
httpd-2.2.25-1.el6.x86_64.rpm
