红帽企业版 as4 用centos源升级

去 搜索yum 

然后安装。

rpm -ivh yum-2.4.2-0.4.el4.rf.noarch.rpm
可能会提示缺少一些文件或者模块，按照名字在rpmfind.net里面搜索

error: Failed dependencies:
        python-elementtree is needed by yum-2.4.2-0.4.el4.rf.noarch
        python-sqlite is needed by yum-2.4.2-0.4.el4.rf.noarch
        urlgrabber is needed by yum-2.4.2-0.4.el4.rf.noarch

 

然后

导入一个GPG-KEY

rpm --import /usr/share/rhn/RPM-GPG-KEY

 还要修改一下/etc/yum.repos.d/CentOS-Base.repo
才可以yum升级，把/etc/yum.repos.d/CentOS-Base.repo的内容替换为：


[base]
name=CentOS-4 - Base
baseurl=
gpgcheck=1

#released updates
[update]
name=CentOS-4 - Updates
baseurl=
gpgcheck=1

#packages used/produced in the build but not released
[addons]
name=CentOS-4 - Addons
baseurl=
gpgcheck=1

#additional packages that may be useful
[extras]
name=CentOS-4 - Extras
baseurl=
gpgcheck=1

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-4 - Plus
baseurl=
gpgcheck=1
enabled=0

#contrib - packages by Centos Users
[contrib]
name=CentOS-4 - Contrib
baseurl=
gpgcheck=1
enabled=0

#packages in testing
[testing]
name=CentOS-4 - Testing
baseurl=
gpgcheck=1
enabled=0


rpm --import 解决yum问题

 然后现在就可以进行升级了

centos-release-4-4.3.i386.rpm yum-2.4.3-3.el4.centos.noarch.rpm
