给你的Red Hat Linux 5 搭建本地yum源

Red Hat的yum 工具给软件安装带来了极大的方便，节省了寻找依赖软件的时间。这里主叫介绍了一下在Red Hat Linux 5.x中搭建本地的yum源。方法介绍如下：

1) 挂在Redhat linux 5.X光盘：
如果光驱是自动加载的，就不用mount了，直接拷贝文件即可
# mkdir /usr/local/osfiles
# cp -r /media/RHEL_5*/* /usr/local/osfiles

如果光驱不是自动加载的，则操作如下
# mount /dev/cdrom /mnt
# mkdir /usr/local/osfiles
# cp -r /mnt/* /usr/local/osfiles

2) 编辑/etc/yum.conf 增加下面的内容即可

[cdrom]
name=cdrom
baseurl=file:///usr/local/osfiles/Server
enabled=1
gpgcheck=1

可能遇到的问题：
1. 如果在安装软件时出现：类似 Public key for ****.rpm is not installed 的错误。则用root用户执行如下操作：
# rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

2. 如果出现了后面的错误(can not find RHNS CA file)，可以通过如下方式解决：
# cp /usr/share/rhn/RHNS-CA-CERT /usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT
# yum clean all

错误信息：
