RHEL 6.3使用CentOS yum源 (redhat yum安装失败)

由于Redhat的yum在线更新是收费的,如果没有注册的话是不能使用的,即不能在线安装软件。所以yum install 命令每次都安装失败

下面介绍一种更改yum源的方式:

系统说明:

系统:Red Hat Enterprise Linux Server 6.3

内核:Linux 2.6.32-279.el6.x86_64

1、删除RHEL原有的yum
     rpm
-aq|grep yum|xargs rpm -e --nodeps  #删除

2、下载新的yum安装包  #这里我们使用CentOS的yum源
       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-3.2.29-60.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

(提示:如果下载时提示404找不到错误,请访问http://mirrors.163.com/centos/6/os/x86_64/Packages/,手动查找上面四个包,有时候版本会有点小偏差)

3、安装yum软件包

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-3.2.29-60.el6.centos.noarch.rpm   yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

(这里要注意的是:最后两个安装包要放在一起同时安装,否则会提示相互依赖,安装失败。)

4、更改yum源  #我们使用网易的CentOS镜像源

cd /etc/yum.repos.d/

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

vi CentOS6-Base-163.repo  #编辑文件

把文件里面的$releasever全部替换为版本号,即6 最后保存!

或者直接把下面的内存拷贝到CentOS6-Base-163.repo文件中即可

(已经修改好,不用下载直接新建CentOS6-Base-163.repo 也     可以)

# 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.

5、收尾,测试YUM 是否可用

yum clean all     #清理yum缓存

yum makecache     #将服务器上的软件包信息缓存到本地,以提高搜索安装软件的速度

yum install vim*  #测试yum是否可用
