基于VMwarevCenter Server中的Linux RedHat 6.4 安装Oracle 11GR2 11.2.0.4 RAC集群
其中public和private要划分到不同的网段。保证安全传输
[root@Zracnode1~]# cat /etc/hosts

共享磁盘配置有多种方式，nfs，磁盘阵列直接映射划分，我这里采用的是通过vmware vCenter server上的共享磁盘技术，操作步骤如下：
3.1. 需要对SCSI 控制器，进行配置。对总线配置为[物理]模式。参数解释如下：
选项 |
描述 |
无 |
其他虚拟机不能共享虚拟磁盘。 |
虚拟 |
同一台服务器上的虚拟机可以共享虚拟磁盘。 |
物理 |
任何服务器上的虚拟机均可共享虚拟磁盘。 |
3.2 新建SCSI controller 1控制器，并设置相关参数，VmwarevCenter操作页面如下：
3.3 新建硬盘，硬盘类型为[Thick provision eager zeroed].并且设置virtual Device Node为[SCSI(1:0)].在设置磁盘模式为[Independent-Persistent].操作页面如下：
3.4 添加已存在磁盘，在ZRAC02节点上面，添加磁盘。操作页面如下：
挂载镜像配置yum
mount -oloop -t iso9660 /u01/software/rhel-server-6.4-x86_64-dvd.iso /u01/iso
[root@Zracnode1u01]# cat /etc/yum.repos.d/rhel-source.repo
[Server]
name=Server
baseurl=file:///u01/iso
gpgcheck=0
gpgkey=file:///u01/iso/RPM-GPG-KEY-redhat-release
VNC在Linux上的安装
#yuminstall tigervnc-server
#vncserver #该命令在服务器端启动一个VNC进程。允许一个
VNC View连接进来；如果需要多个View连接到服务器，需要多次执行上述命令；
Password: # 为了不想任何人都可以任意遥控此计算机。因此当第1次启动VNC server时，会要求设置网络遥控的密码。
Verify: # 验证密码；
进入root主目录下的.vnc隐含目录, 找到 xstartup文件并编辑：
# cd/root/.vnc
# vi xstartup
# twm& （注释掉该行）
startkde& （添加该行）
# killallXvnc
#vncserver
