redhat6配置centos的yum源

由于redhat6自带的yum要注册才能用,所以用centos的免费yum来替换redhat的收费yum。
环境:redhat6.8
具体步骤:
1.删除redhat6自带的yum
rpm -aq|grep yum|xargs rpm -e –nodeps
2.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-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm   //这两个文件要一起安装,因为这两个文件相互依赖
相关文件下载:
//centos镜像源
//163镜像源
3.备份原来的yum源配置文件
mv /etc/yum.repos.d/rhel-source.repo /etc/yum.repos.d/rhel-source.repo.bak
4.更改yum源(使用网易163的centos镜像源)
cd /etc/yum.repos.d
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
5.修改CentOS6-Base-163.repo文件
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)

# 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.
