現需要在RHEL6.6上安裝zabbix2.4，通過虛擬機橋接互聯網yum方式安裝，但yum –y installnet-snmp zabbix zabbix-server的時候報如下錯誤，導致安裝不上：
這個錯誤是由於沒有註冊引起的，怎麼辦呢？網上也查了一些資料，按照網上的資料，現將爲自己的環境整理搭建了一下CentOS6.6 yum源！
把原來的yum源卸載掉
# rpm -qa | grep yum | xargs rpm -e –nodeps
添加並安裝下載的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]：最後這兩個包必須同時安裝，因兩個是相互依賴關係。
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緩存
# yum makecache //將服務器上的軟件包信息緩存到本地，以提高搜索安裝軟件的速度
# yum install vim* //測試yum是否可用
至此，搭建CentOS6.6的yum源已成功。
