仍然是yum问题rhel6使用centos的yum源

1.将centos的yum文件全部拷贝过来，不过实际只是用了Base的文件

[root@server yum.repos.d]# ls
CentOS-Base.repo  CentOS-Debuginfo.repo.b  CentOS-Media.repo.b  server.repo.b

2.查看一下文件吧，学到以下几点

enabled=0 不启用该yum；

[root@server yum.repos.d]# cat CentOS-Base.repo
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
