RedHat6.6 更换CentOS6 yum和yum源

redhat默认自带的yum源需要注册，才能更新，报错：
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
可替换为centos对应的源。 操作如下：

 

1、删除redhat原有的yum

 

rpm -aq|grep yum|xargs rpm -e –nodeps

 

 

2、下载yum安装文件

 

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm

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

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm

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

 

 

 

3、安装组件

 

 

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

 下面安装失败了

# rpm -ivh yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm
warning: yum-3.2.29-81.el6.centos.noarch.rpm:Header V3 RSA /SHA1 Signature, key ID c105b9de: NOKEY

       python-urlgrabber >= 3.9.1-10 is needed byyum-3.2.29-81.el6.centos.noarch
You have new mail in /var/spool/mail/root

 

少python-urlgrabber 组件，下载：

 

http://mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm

 

# rpm -ivh python-urlgrabber- 3.9 . 1 - 11 .el6.noarch.rpm

下载个python2.6重装

 

wget ftp://mirror.switch.ch/pool/4/mirror/scientificlinux/6.5/x86_64/updates/security/python-2.6.6-64.el6.x86_64.rpm

 ----查看当前python rpm版本----

------------

#rpm -e python-2.6.6-52.el6.x86_64 --nodeps
# rpm -ivh python-2.6.6-64.el6.x86_64.rpm

 

有报错，需要依赖包，继续

# rpm -ivh python-libs- 2.6 . 6 - 64 .el6.x86_64.rpm python- 2.6 . 6 - 64 .el6.x86_64.rpm --nodeps  --force

 

warning:python-libs- 2.6 . 6 - 64 .el6.x86_64.rpm: Header V3 RSA/SHA1 Signature, key IDc105b9de: NOKEY

  1 :python                ########################################### [ 50 %]
  2 :python-libs           ########################################### [ 100 %]

没问题，可以继续

 

Phtyon url 也要粗暴下

# rpm -ivh python-urlgrabber- 3.9 . 1 - 11 .el6.noarch.rpm --nodeps --force
warning:python-urlgrabber- 3.9 . 1 - 11 .el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key IDc105b9de: NOKEY
Preparing...               ########################################### [ 100 %]
  1 :python-urlgrabber     ########################################### [ 100 %]

 

 

 

安装yum

 

# rpm -ivh yum- 3.2 . 29 - 81 .el6.centos.noarch.rpm yum-plugin-fastestmirror- 1.1 . 30 - 37 .el6.noarch.rpm
warning:yum- 3.2 . 29 - 81 .el6.centos.noarch.rpm: Header V3 RSA/SHA1 Signature, key IDc105b9de: NOKEY
Preparing...               ########################################### [ 100 %]
  1 :yum-plugin-fastestmirro########################################### [ 50 %]
  2 :yum                   ########################################### [ 100 %]

 

 

 

 订阅就不要了，反正也没钱

# rpm -qa | grep subsc*
subscription-manager- 1.12 . 14 - 7 .el6.x86_64
# rpm -e subscription-manager- 1.12 . 14 - 7 .el6.x86_64

4、设置yum

下载repo文件 到  /etc/yum.repos.d/

http://mirrors.163.com/.help/CentOS7-Base-163.repo

 把文件里面的$releasever全部替换为版本号：6

清除原有缓存，重建缓存，更新

1.     yum clean all

2.     yum makecache

3.     yum update

 

 

 

    完成
