首先到http://wiki.centos.org/zh/AdditionalResources/Repositories/RPMForge找下最新的源文件

如我使用的是centos5.4

找到对应的 i386 http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm

下载后执行rpm -i rpmforge-release-0.5.2-2.el5.rf.i386.rpm

接着执行 yum install rrdtool 进行安装

成功后执行rrdtool -v 出现如下提示：恭喜你成功哦
