问题:redhat 6.4 默认自带的 yum 源需要注册,才能更新。

解决方案:删除默认的yum源,手动配置Centos 6.5的yum源。

我这里的系统是RedHat 6.4的所以在 http://mirrors.163.com/centos/6/os/x86_64/Packages/  下载相关rpm包


1.首先查找系统自动安装了那些yum包

   # rpm -qa | grep yum

2.删除默认安装的yum包,不检查依赖关系

   # rpm -qa | grep yum | xargs rpm -e --nodeps

3.再次查看是否删除成功

   # rpm -qa | grep yum

4.下载新的yum包

   # wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm  

   # wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-69.el6.centos.noarch.rpm 

   # wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

   # wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm  

5.安装yum包

   # rpm -ivh  python-iniparse-0.3.1-2.1.el6.noarch.rpm 

   # rpm -ivh  yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

   # rpm -ivh  yum-3.2.29-69.el6.centos.noarch.rpm  yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

6.提供yum源的配置文件

   # cd /etc/yum.repos.d/

   # wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo

   # vim CentOS6-Base-163.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.

PS:编辑配置文件,把文件里面的$release全部替换为版本号,即6.5 最后保存。

7.清除原有缓存

   # yum clean all

8.重建缓存,以提高搜索安装软件的速度

   # yum makecache

9.最后更新下

   # yum update
