rpm -ivh http://mirror.centos.org/centos/7/os/x86_64/Packages/ftp-0.17-67.el7.x86_64.rpm


1、本人环境

　　centos6.5 32位

2、进入 http://mirror.centos.org/centos/6/os/ ，根据系统位数进入相应的目录，我的为32位因此进入http://mirror.centos.org/centos/6/os/i386/Packages/，

　　搜索找到ftp的rpm package的地址然后执行: rpm -Uvh http://mirror.centos.org/centos/6/os/i386/Packages/ftp-0.17-54.el6.i686.rpm 命令
