[root@JW31 yum.repos.d]# rpm -qa |mysql
-bash: mysql: command not found

wget -c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-server-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/

wget -c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-client-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/

wget -c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-devel-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/

　　3：利用超级终端把下载好的三个文件复制到  /media/www/CentOS
