新安装了redhat6.5.安装后,登录系统,使用yum update 更新系统。提示:
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
无法更新。
redhat 默认自带的 yum 源需要注册,才能更新。我们想不花钱也可以更新,需要替换掉redhat的yum源。
1.检查是否安装yum包
查看RHEL是否安装了yum,若是安装了,那么又有哪些yum包:
[root@localhost ~]# rpm -qa |grep yum
yum-metadata-parser-1.0-8.fc6
yum-3.0.1-5.el5
yum-rhn-plugin-0.4.3-1.el5
yum-updatesd-3.0.1-5.el5
2 删除redhat自带的yum包
卸载上面显示的所有yum包:
[root@localhost ~]# rpm -qa|grep yum|xargs rpm -e --nodeps(不检查依赖,直接删除rpm包)
再用
[root@localhost ~]# rpm -qa |grep yum
[root@localhost ~]#
查看,无信息显示表示已经卸载完成。
3.下载新的yum包。使用Centos6.5的yum包
安装yum软件包
注意:单个的安装包可能会依赖其它包(例如yum和yum-fastestmirror会相互依赖),所以我们可以把所有这些包放在一起,用一行命令将它们同时安装即可:
-
rpm -ivh yum-metadata-parser-1.1.2-16.el6.i686.rpm yum-3.2.29-40.el6.centos.noarch.rpm yum-3.2.29-40.el6.centos.noarch.rpm
4.更换yum源。使用163的源
-
# cd /etc/yum.repos.d/
-
# wget
-
# vi CentOS6-Base-163.repo
编辑文件,把文件里面的$releasever全部替换为版本号,即6.5 最后保存!或者直接把下面的内存拷贝到CentOS6-Base-163.repo文件中即可(已经修改好)
-
# 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.

5.清除原有缓存
重建缓存,以提高搜索安装软件的速度
6.更新系统
