安装lftp
第一步： 安装gcc-c++编译环境，收集rpm安装包。我所用的centOS 系统需要七个rpm包，它们分别是：mpfr-2.4.1-6.el6.x86_64.rpm 、ppl-0.10.2-11.el6.x86_64.rpm、cloog-ppl-0.15.7-1.2.el6.x86_64.rpm、cpp-4.4.7-17.el6.x86_64.rpm、libgcc-4.4.7-17.el6.x86_64.rpm、 libgomp-4.4.7-17.el6.x86_64.rpm、rpm-ivh gcc-4.4.7-17.el6.x86_64.rpm 。 其他版本的系统可能需要不同的rpm包，这里为大家提供一个可以下载更多rpm 包的站点，方便大家下载自己所需要的rpm安装包。 站点地址是：ftp://mirror.switch.ch/mirror/centos/6/os/x86_64/Packages/ （这个站点地址是在网上找的，内容很丰富，很有用！非常感谢该站点的创建者为大家共享了这么多优质资源）
