1.在使用 yum 安装的时候报错

[root@rac1 yum.repos.d]# yum install oracle-rdbms-server-11gR2-preinstall
Loaded plugins: refresh-packagekit, security
http://public-yum.oracle.com/repo/OracleLinux/OL6/UEK/base/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'public-yum.oracle.com'" Trying other mirror.
Error: failure: repodata/primary.xml.gz from ol6_latest: [Errno 256] No more mirrors to try.

解决方法一: /etc/resolv.conf 中添加 nameserver 8.8.8.8 (注意：这是google 的服务,如果网上慢安装的就慢)

解决方法二: 使用 本地的 yum 资源 一下是操作

[root@rac1 yum.repos.d]# cd /etc/yum.repos.d
[root@rac1 yum.repos.d]# ls
public-yum-ol6.repo
[root@rac1 yum.repos.d]# mv public-yum-ol6.repo public-yum-ol6.repo.bak
[root@rac1 yum.repos.d]# vi public-yum-ol6-local.repo
[oel6_local]
name = Enterprise Linux 6.3 DVD
baseurl=file:///mnt/cdrom/Server/
gpgcheck=0
enabled=1

在 virtualBox 中挂上 oracle-linux-6.3.iso

[root@rac1 yum.repos.d]# cd /mnt
[root@rac1 mnt]# mkdir cdrom
[root@rac1 mnt]# mount /dev/cdrom /mnt/cdrom/
mount: block device /dev/cdrom is write-protected, mounting read-only
[root@rac1 mnt]# yum install oracle-rdbms-server-11gR2-preinstall
