RHEL6:配置yum本地安装源

有时候需要从光盘里安装packages.
这就需要先配置yum的repos，让它从本地光盘里找packages.

挂载RHEL6系统光盘

首先挂载RHEL6光盘。
如果是硬盘上的iso文件，比如光盘路径是/tmp/rhel6.iso 那么执行下面命令将iso挂载到/mnt

# mount -o loop /tmp/rhel6.iso /mnt

如果是光盘(或者是从虚拟机插入)，执行下面命令将光盘挂载到/mnt

# mount /dev/sr0 /mnt

挂载后，应该能看到/mnt下有光盘的内容。

# ls /mnt/

配置yum repos

挂载好光盘后，配置yum的repos.
新建一个repo配置文件

# vim /etc/yum.repos.d/my.repo

[RHEL]
name=RHEL
baseurl=file:///mnt
enabled=1
gpgcheck=0

保存。

测试

尝试安装dhcp服务

# yum install dhcp

成功配置的话能看到如下画面
yum
