RHEL6.5更换本地YUM源

引言：由于RHEL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。在这种情况下，想使用RHEL系统，还想用yum源来在线安装软件，有没有办法？答案是有办法，请往下看！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://vault.centos.org/6.0/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
wget http://vault.centos.org/6.0/os/x86_64/Packages/yum-metadata-parser-1.1.2-14.1.el6.x86_64.rpm
wget http://vault.centos.org/6.0/os/x86_64/Packages/yum-3.2.27-14.el6.centos.noarch.rpm
wget http://vault.centos.org/6.0/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm
3、安装yum软件包rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.2-14.1.el6.i686.rpm
rpm -ivh yum-3.2.27-14.el6.centos.noarch.rpm
rpm -ivh yum-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm

注意：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）
# 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.
