redhat6.9 替换CentOS yum源

1，查看原有yum包

# rpm -qa|grep yum

2，卸载yum包

# rpm -qa|grep yum|xargs rpm -e --nodeps

3.下载163yum包

https://mirrors.aliyun.com/centos/6.10/os/x86_64/Packages/

在里面找到下面4个文件，

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

yum-3.2.29-81.el6.centos.noarch.rpm

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

yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm

4.安装软件包

# rpm -ivh yum-* --nodeps

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

5.移走repo

# cd /etc/yum.repos.d/

# mv r* /opt

6，下载163源

# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

7.修改文件中的 $releasever 全部修改为目标版本6#为防止出错，$basearch全部替换成x86_64

:%s@$releasever@6@g

:%s@$basearch@x86_64@g

8，更新一下yum和加载缓存

# yum clean all &&yum makecache

9.测试是否正常。

# yum -y install lrzsz vim
