3.theversion between redhat and centos is same ,such as ,redhat 4---centos---4,My redhat version is as5.2(this version is core version) ,so Ichoose centos 5.2

 

solution:

1.remove yum for redhat which has been installed on your localmachine.

  commend: rpm -aq|grep yum (you will get a list of yum packages)

                 rpm -e (remove these packages)

2.installyum for centos ,you can download a yum for centos from websietes,Iforgot where I get it ,But I remeber the  file name should be'***.i386.norch.rpm' (my localmation is 32 bits).if you got somedependencies ,you can install them first.
