1、本地源配置：cdiso.repo
将iso镜像文件中所有内容复制到/public/software/cdrom 中，节点将本地yum指向此处。
[root@node19 ~]# vim /etc/yum.repos.d/cdiso.repo [cd1] name=cd1 baseurl=file:///public/software/cdrom enabled=1 gpgcheck=0
2、本地源配置：file.repo
mount -o loop xxxx.iso /mnt/iso
如果/etc/yum.repos.d/下面有其它的*.repo文件，先创建个备份文件夹，将这些repo先转移到文件夹中，自己写一个新的.repo的文件
vi /etc/yum.repos.d/file.repo 添加如下内容： [base] name=rhel6repo baseurl=file:///mnt/iso enabled=1 gpgckeck=0 gpgkey=file:///mnt/iso/RPM-GPG-KEY-redhat-release 5.清除cache yum clean all 6.验证是否成功 yum -y install tree tree
3、网络源配置
