1、背景说明
Dell 720上面装了RHEL6.8。而RHEL6上的yum源只能注册账户才能使用，故需要进行yum源替换
2、步骤
1、删除rhel自带的yum源 rpm -qa|grep yum|xargs rpm -e --nodeps rpm -qa |grep yum 2、下载新的yum安装包 wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm 友情提醒：这些rpm包小版本号会变更，所有复制此链接时，如果报404错误，请登入此网页并查看具体小版本号 注意：很多网上提供的镜像源中所涉及的 yum-3.2.29-69.el6.centos.noarch.rpm此安装包已经没有了 把69变成81就有 3、安装yum包，有依赖关系，三个一起安装 rpm -ivh yum-3.2.29-30.el6.noarch.rpm yum-metadata-parser-1.1.2-16.el6.x86_64.rpm yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm warning: yum-3.2.29-30.el6.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY warning: yum-metadata-parser-1.1.2-16.el6.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY Preparing... ########################################### [100%] 1:yum-metadata-parser ########################################### [ 33%] 2:yum ########################################### [ 67%] 3:yum-plugin-fastestmirro########################################### [100%] 4、将rhel自带的yum仓库文件移走 yum.repos.d]# mkdir bak yum.repos.d]# mv mirrors-rpmforge* bak/ yum.repos.d]# mv rh* bak/ yum.repos.d]# ls bak epel.repo packagekit-media.repo CentOS6-Base-163.repo epel-testing.repo rpmforge.repo yum.repos.d]# mv packagekit-media.repo bak/ 5、更改163的yum源 yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo --2017-04-11 02:23:41-- http://mirrors.163.com/.help/CentOS6-Base-163.repo Resolving mirrors.163.com... 123.58.173.185, 123.58.173.186 Connecting to mirrors.163.com|123.58.173.185|:80... connected.
