附repo内容

1. # CentOS-Base.repo
   
2. #
   
3. # The mirror system uses the connecting IP address of the client and the
   
4. # update status of each mirror to pick mirrors that are updated to and
   
5. # geographically close to the client.  You should use this for CentOS updates
   
6. # unless you are manually picking other mirrors.
   
7. #
   
8. # If the mirrorlist= does not work for you, as a fall back you can try the
   
9. # remarked out baseurl= line instead.
   
10. #
