1.redhat在使用yum时报错
[root@redhat58 ~]# yum install -y unzip zip
Loaded plugins: katello, product-id, security, subscription-manager
Updating certificate-based repositories.
Unable to read consumer identity
Setting up Install Process
Nothing to do
2.需要更新yum源，将redhat的yum源替换成centos的源
[root@redhat58 packager512]# cd /etc/yum.repos.d/
[root@redhat58 yum.repos.d]# ll
total 16
-rw-r--r-- 1 root root 190 Apr 12 22:40 redhat.repo
-rw-r--r-- 1 root root 254 Jan 24 2012 rhel-debuginfo.repo
如果没有rhel-source.repo文件，则需要新建
[root@redhat58 yum.repos.d]# vi rhel-source.repo
在rhel-source.repo中填入一下内容
# 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.
