rhel6.5 yum配置centos6.5

rhel6.5 yum配置主要步骤

1.删除redhat原有的yum 

rpm -aq|grep yum|xargs rpm -e --nodeps      

2.下载yum安装文件（查看系统版本uname -r /uname -p  cat /etc/issue）

python-iniparse-0.3.1-2.1.el6.noarch.rpm      

yum-metadata-parser-1.1.2-16.el6.x86_64.rpm      

yum-3.2.29-40.el6.centos.noarch.rpm      

yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm       

3.配置repo文件，放到/etc/yum.repos.d/下（从http://mirrors.163.com/.help/CentOS6-Base-163.repo下载）      

编辑文件，把文件里面的$releasever全部替换为版本号，即6.5 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

# 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.

4.yum clean all没有问题 yum makecache报错 rhel6.5 Couldn't resolve host 'mirrors.163.com

5.检查网络ping www.baidu.com不通，断定是网络问题，关防火墙，设置DNS，虚拟机 桥接模式改为自定义，

cat /etc/sysconfig/network-scripts/ifcfg-eth0/eth1都设置本地电脑的DNS

6 成功；
