redhat6.5 配置使用centos的yum源

新安裝了redhat6.5安裝後，登陸系統，使用yum update 更新系統。提示：

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

沒法更新。

redhat 默認自帶的 yum 源須要註冊，才能更新。咱們想不花錢也能夠更新，須要替換掉redhat的yum源。

1.檢查是否安裝yum包

查看RHEL是否安裝了yum，如果安裝了，那麼又有哪些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.el

 

2 刪除redhat自帶的yum包

卸載上面顯示的全部yum包：

[root@localhost ~]# rpm -qa|grep yum|xargs rpm -e --nodeps（不檢查依賴，直接刪除rpm包）

再用

[root@localhost ~]# rpm -qa |grep yum

[root@localhost ~]# 

查看，無信息顯示錶示已經卸載完成。

3.下載新的yum包。使用Centos6.5的yum包

 # wget http://mirrors.163.com/centos/6.5/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm

# wget http://mirrors.163.com/centos/6.5/os/i386/Packages/yum-3.2.29-40.el6.centos.noarch.rpm

# wget http://mirrors.163.com/centos/6.5/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

安裝yum軟件包

注意:單個的安裝包可能會依賴其它包（例如yum和yum-fastestmirror會相互依賴），因此咱們能夠把全部這些包放在一塊兒，用一行命令將它們同時安裝便可：

 rpm -ivh yum-metadata-parser-1.1.2-16.el6.i686.rpm yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

 4.更換yum源。使用163的源

# cd /etc/yum.repos.d/
# wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo
# vi CentOS6-Base-163.repo

 編輯文件，把文件裏面的$releasever所有替換爲版本號，即6.5（:1,$s/$releasever/6.5而後按enter建) 最後保存！或者直接把下面的內存拷貝到CentOS6-Base-163.repo文件中便可（已經修改好）

# 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.清除原有緩存

 yum clean all

 重建緩存，以提升搜索安裝軟件的速度

 yum makecache

 6.更新系統
