redhat6添加yum_redhat6 yum

64位Redhat6.6未注册 ，yum改成 CentOS6.6 的方法

1.删除rhel6.6自带的yum：
命令如下：    rpm -qa | grep yum | xargs rpm -e --nodeps


2.下载CentOS 6.6的yum，命令如下： 

【 注意】先访问http://mirrors.163.com/centos/6/os/x86_64/Packages/，看看里面的版本号更新了没，要同步，否则会失败。
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-metadata-parser-1.1.2-16.el6.x86_64.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


3.安装yum： 
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

 

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

4.配置repo文件： 

在/etc/yum.repos.d/目录下去除原有的*.repo文件，新建一个新的CentOS-Base.repo文件，该文件的内容如下：
##CentOS-Base.repo
###【注意啦】下面代码中为了通用性用$releasever指代版本号，如果你要更新6.6的就写6.6,其他版本可照猫画虎。
[base]
name=CentOS-$releasever-Base-163.com
baseurl=http://mirrors.163.com/centos/6/os/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6


#released updates 
[updates]
name=CentOS-$releasever-Updates-163.com
baseurl=http://mirrors.163.com/centos/6/updates/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6


#additional packages that may be useful
[extras]
name=CentOS-$releasever-Extras-163.com
baseurl=http://mirrors.163.com/centos/6/extras/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6


#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever-Plus-163.com
baseurl=http://mirrors.163.com/centos/6/centosplus/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6


#contrib - packages by Centos Users
[contrib]
name=CentOS-$releasever-Contrib-163.com
baseurl=http://mirrors.163.com/centos/6/contrib/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

方法二

下载repo文件 到  /etc/yum.repos.d/

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

5.清除原有缓存：

yum clean all 

6.重建缓存，以提高搜索安装软件的速度:

yum makecache

7.更新系统 :  

yum update (时间会比较久)


至此就完成对yum源的配置，接下来就可使用yum 进行软件升级与安装。
