RedHat Enterprise Linux6.4 使用CentOS yum源

猫猫1

　　

[admin@server1 ~]$ uname -a
Linux server1 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux
　　
　　


　　在使用redhat linux的yum来安装或者更新软件的时候会提示



[admin@server1 ~]$ sudo yum install gcc
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Setting up Install Process
No package gcc available.
Error: Nothing to do
　　


　　[注]请以root身份操作

由于 redhat的yum在线更新是收费的，如果没有注册的话不能使用，如果要使用，需将redhat的yum卸载后，重启安装，再配置其他源

解决办法：

1、首先到http://mirrors.163.com/centos下载软件包
　　

　　x86 地址：http://mirrors.163.com/centos/6/os/i386/Packages/
　　x86_64 地址：http://mirrors.163.com/centos/6/os/x86_64/Packages/
　　


　　必要下载的软件包有（以64位系统为例）：
　　1>  python-iniparse-0.3.1-2.1.el6.noarch.rpm
　　2>  yum-3.2.29-40.el6.centos.noarch.rpm
　　3>  yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
　　4>  yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

　　下载命令：

　　

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-3.2.29-40.el6.centos.noarch.rpm
　　

　　

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
　　

　　

[注] :版本不一定要最新的(http://mirrors.163.com/centos/6/os/x86_64/Packages/ 查找对应版本)



2、卸载RedHat自带的yum
　　

　　

rpm -qa | grep yum | xargs rpm -e --nodeps
　　

　　
　　
　　 注：1>   xargs是一条Unix和类Unix操作系统的常用命令。它的作用是将参数列表转换成小块分段传递给其他命令，以避免参数列表过长的问题

                 2>   --nodeps  强制卸载,不管依赖性



3、安装下载的centos的yum包：

　　

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
rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
　　

　　[注] :最后2个需要一起安装，否则会出现依赖性错误



4、到http://mirrors.163.com的 centos帮助文档 中下载CentOS6-Base-163.repo文件，存放到/etc/yum.repo.d中

　　

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

　　

5、编辑CentOS6-Base-163.repo文件，将其中的$releasever更改为centos的版本号

　　下面是修改好的：
　　

# 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.
#
#

6、yum clean all 清除原有缓存

7、yum makecache  获取yum列表

出现下面提示，表示yum更改完成：
