red hat 更换yum源

32饿312

## 一 故障说明

- 环境

```

Red Hat Enterprise Linux Server release 6.4 (Santiago)

```

- 故障描述

```
使用yum安装时出现Loaded plugins: product-id, security, subscription-manager This system is not registered to Red Hat

提示未注册
```

## 二 解决

- 卸载yum包

```
- 1.检查是否安装yum包
查看RHEL是否安装了yum，若是安装了，那么又有哪些yum包：
[iyunv@localhost ~]# rpm -qa |grep yum
yum-metadata-parser-1.0-8.fc6
yum-3.0.1-5.el5
yum-rhn-plugin-0.4.3-1.el5
yum-updatesd-3.0.1-5.el5
2 删除redhat自带的yum包

[iyunv@localhost ~]# rpm -qa|grep yum|xargs rpm -e --nodeps

查看，无信息显示表示已经卸载完成。

```

- 安装yum 包

安装地址：
http://mirrors.163.com/centos/6.8/os/x86_64/Packages/

```
yum-metadata-parser

yum-3.2

yum-plugin-fastestmirror



```

- 安装过程中提示 :

python-urlgrabber 版本过低

```

```

同样的方法下载 并安装 python-urlgrabber

由于有依赖关系存在，所以
安装上述四个包的时候
我们一起安装

```
rpm -ivh  yum-metadata-parser  yum-3.2  yum-plugin-fastestmirror


```

## 更换163源


```

cd /etc/yum.repos.d/
wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo
vi CentOS6-Base-163.repo

#替换版本信息
sed -i 's/$releasever/6.8/g' CentOS6-Base-163.repo

yum clean all
#重建缓存
yum makecache

#然后更新系统

yum update
```
