在vmware vsphere esxi上安装oracle RAC(3)

4. 为第一个RAC节点准备虚拟机环境

本节安装步骤简介如下: ? ? ?

使用vSphere Client创建第一个虚拟机。添加公网和心跳网卡，挑选适当的LUN创建仲裁盘CRS （VMDK模式）。

安装Redhat Linux操作系统，安装VMware tools，按照Oracle RAC要求安装相应补丁. 在Linux中配置NTP 客户端.

4.1 创建第一个虚拟机

1. 使用vSphere Client登录vCenter.

2. 选中一台主机,在Getting Started页面单击Create a new virtual machine.

3. In the Create New Virtual Machinewizard, select Typical for the Configuration, and click Next. 4. On the Name and Location page, enter RAC1 for the Name, and click Next. 5. On the Datastore page, select VMDATASTORE, and click Next.

6. On the Guest Operating System page, select Linux from the Guest Operating System list. For the

Version, select Oracle Linux 6 (64-bit) from the drop-down menu. Click Next. 7. On the Create a Disk page, set the Virtual Disk Size to 20GB, and click Next.

8. On the Ready to Complete page, select Edit the virtual machine settings before completion.

Click Continue. 9. On the Virtual Machine Properties page for theRAC1 virtual machine, select 8CPUs and

128GBMemory. 10. Click Finish.

4.2 增加两个虚拟网卡

现在需要增加两块网卡. 一块用于公共数据网络, 另一块用于心跳网络.添加这两块网卡的过程基本相同,差别仅在于添加公网网卡时选择标签:VM Net而添加心跳网卡时选择Oracle HB. 添加公网网卡的步骤： 1. Select a virtual machine.

2. Click Edit settings to display the Virtual Machine Properties pane. 3. Click Add.

4. Select Ethernet Adaptor and click Next to display the Add Hardware wizard.

5. On the Network connection page, select VMXNET 3 from the Adapter Type drop-down menu. 6. In the Network Connection section of the Network connection page, select Named network with

specified label. 7. In the Named network with specified label drop-down menu, select VM Net.

8. In the Device Status section of the Network connection page, select Connect at power on. 9. On the Ready to Complete page, click Finish, and then click OK. 添加心跳网卡的步骤：

1. Repeat steps 1 through 6 from the preceding procedure.

2. In the Named network with specified label drop-down menu, select Oracle HB. 3. Continue with steps 8 and 9 from the preceding procedure.

4.3 添加仲裁盘

Oracle RAC需要至少一个共享的仲裁盘存放clusterware信息和节点投票信息。存储管理员需要事先为仲裁盘分配好单独的LUN，然后我们需要创建单独的SCSI控制器并设为Paravirtual驱动.SCSI 总线sharing policy 设为none.

下面描述创建共享存储的步骤. 为虚拟机创建20GB datastore：

1. In vSphereClient, select a virtual machine.

2. Right-click the name of the virtual machine and select Edit Settings to display the Virtual Machine

Properties pane. 3. Click Addto display the Add Hardware wizard.

4. In the Add Hardware wizard select Hard Disk for the Device Type, and click Next.

5. In the Disk section of the Select a Disk page, select Create a new virtual disk. Set the disk size to

20GB, select the Support clustering features such as Fault Tolerance check box, and select CRS1 to specify a datastore. Also, for vSphere 5, in the Disk Provisioning section select Thick Provision Eager Zeroed. Click Next. 6. On the Compatibility Mode page, click Next.

7. On the Advanced Options page, in the Virtual Device Node section, select SCSI (1:0). In

theMode section, selectIndependent. Click Next. 8. On the Ready to Complete page, click Finish. 9. Click OK.

Add configuration parameters for each Oracle RAC virtual machine as described in Disabling simultaneous write protection provided by VMFS using the multi-writer flag(http://kb.vmware.com/kb/1034165). 手工修改虚拟机参数

1. In vSphereClient, select a virtual machine.

2. Right-click the name of the virtual machine and select Edit Settings to display the Virtual Machine

Properties pane. 3. Click the Options tab, click Advanced, and click General. 4. Click Configuration Parameters.

5. On the Configuration Parameters page, add rows and entries for the shared disks in the virtual

machine's configuration parameters as shown in the following screenshot. 6. Repeat steps 1 through 5 for each of the remaining virtual machines.
