现需要在RHEL6.6上安装zabbix2.4，通过虚拟机桥接互联网yum方式安装，但yum –y installnet-snmp zabbix zabbix-server的时候报如下错误，导致安装不上：
这个错误是由于没有注册引起的，怎么办呢？网上也查了一些资料，按照网上的资料，现将为自己的环境整理搭建了一下CentOS6.6 yum源！
把原来的yum源卸载掉
# rpm -qa | grep yum | xargs rpm -e –nodeps
添加并安装下载的yum的rpm包
# rpm -ivhpython-iniparse-0.3.1-2.1.el6.noarch.rpm
# rpm -ivhyum-metadata-parser-1.1.2-16.el6.x86_64.rpm
# rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpmyum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
[注]：最后这两个包必须同时安装，因两个是相互依赖关系。
添加163的yum源
# cd/etc/yum.repos.d/
# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
修改CentOS6-Base-163.repo
#CentOS-Base.repo
#
# The mirrorsystem uses the connecting IP address of the client and the
# update statusof each mirror to pick mirrors that are updated to and
# geographicallyclose to the client. You should use thisfor CentOS updates
# unless you aremanually picking other mirrors.
#
# If the mirrorlist=does not work for you, as a fall back you can try the
# remarked outbaseurl= line instead.

# 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
至此，搭建CentOS6.6的yum源已成功。
