redhat6.7 yum网络源配置

RedHat自带的yum源须要当前系统注册了RHN才能够使用，若是没有注册，当使用yum时，会提示须要注册RHN

若是没有注册RHN，则意味着咱们不能使用RedHat自带的yum源。这个时候，咱们能够使用CentOS系统的yum源，这里以配置网易163yum源为例。

1.首先卸载RedHat资源的yum程序

[root@Oracle12CDB yum.repos.d]# rpm -qa|grep yum|xargs rpm -e --nodeps
[root@Oracle12CDB yum.repos.d]# rpm -aq|grep python-iniparse|xargs rpm -e --nodeps

2.删除RedHat yum的源

[root@Oracle12CDB ~]# cd /etc/yum.repos.d/
[root@Oracle12CDB yum.repos.d]# ls
redhat.repo  rhel-source.repo
[root@Oracle12CDB yum.repos.d]# rm -rf *

3.安装CentOS的源，rpm包对安装顺序有要求，我是使用下面的顺序安装成功的。

rpm -ivh http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm                      
rpm -ivh http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm                  
rpm -ivh http://mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm -nodeps --force    

#下面的这两个包单独安装均失败，一块儿安装才成功
rpm -ivh http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm \             
http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm

这里先安装yum-plugin-fastestmirro提示改包依赖于yum包，安装yum包时则提示依赖于yum-plugin-fastestmirro包，因而直接2个包一块儿装

4.建立repo文件

[root@Oracle12CDB yum.repos.d]# pwd
/etc/yum.repos.d
[root@Oracle12CDB yum.repos.d]# ls
centos6.repo  redhat.repo

这里有两个文件，redhat.repo没有内容，不用管。centos6.repo内容以下：

[base]
name=CentOS-$releasever - Base
baseurl=http://mirrors.163.com/centos/6/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/6/os/x86_64/RPM-GPG-KEY-CentOS-6

#released updates
[updates]
name=CentOS-$releasever - Updates
baseurl=http://mirrors.163.com/centos/6/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/6/os/x86_64/RPM-GPG-KEY-CentOS-6


[extras]
name=CentOS-$releasever - Extras
baseurl=http://mirrors.163.com/centos/6/extras/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/6/os/x86_64/RPM-GPG-KEY-CentOS-6

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
baseurl=http://mirrors.163.com/centos/6./centosplus/$basearch/
gpgcheck=1
enabled=0

5.清除缓存，从新缓存，更新

[root@Oracle12CDB yum.repos.d]# yum clean all
[root@Oracle12CDB yum.repos.d]# yum makecache
