linuxrac安装

⑴ 如何在虚拟机中linux+Oracle10gRAC安装

1 前期准备
在vmware workstation中安装redhat enterprise linux as 4.8，使用vmware Converter转换上传
两台linux到vmware ESXI4.0 虚拟服务器上，如果是个人练习，推荐本地使用vmware server。
官方下载10201_clusterware_linux_x86.zip，10201_database_linux_x86.zip。
2 ESXI下创建共享磁盘
Ø 开启ESXI远程SSH的功能，参加<< Vmware ESXI4.0安装及配置说明文档>>，在虚拟服务器
上使用如下命令创建三个共享磁盘。
vmkfstools -c 200M -a lsilogic -d eagerzeroedthick orcdisk.vmdk
vmkfstools -c 100M -a lsilogic -d eagerzeroedthick votingdisk.vmdk

vmkfstools -c 200M -a lsilogic -d eagerzeroedthick orcdisk.vmdk
vmkfstools -c 100M -a lsilogic -d eagerzeroedthick votingdisk.vmdk
vmkfstools -c 50G -a lsilogic -d eagerzeroedthick asm.vmdk
Ø 在VMware vSphere Client图形界面下配置之前上传的两台linux，将三个磁盘依次添加到linux中，注意：总线不能与linux本地磁盘位于同一总线。比如：linux本地磁盘如果是SCSI0:0，那这三个磁盘可以是SCSI1:0，SCSI1:1，SCSI1:2。
Ø 编辑两台linux的配置文件***.vmx文件，添加disk.locking = "FALSE"，将scsi1.sharedBus = "none"改为scsi1.sharedBus = "VIRTUAL"。
Ø 打开两台linux，使用fdisk –l查看磁盘。在第一台linux中使用fdisk /dev/sd*，*代表具体的盘符，依次创建三个磁盘分区。 分区完以后，我们以sdb1,sdc1,sdd1为例。在第二台linux中使用partprobe扫描分区，然后fdisk –l 再次查看，即可看到sdb1,sdc1,sdd1。
3 修改主机名
vi /etc/hosts
vi /etc/sysconfig/network
在两台linux中将这两个文件中相应的主机名分别改为rac1和rac2。为了使配置生效，reboot.

并在/etc/hosts文件中添加节点IP地址，如：
10.10.5.101 rac1
10.10.5.103 rac1-vip
20.20.20.10 rac-priv
10.10.5.102 rac2
10.10.5.104 rac2-vip
20.20.20.11 rac2-priv
vip地址必须和真实ip地址同一网段，priv私有IP地址只要两台机器在同一网段即可。

⑶ 如何在虚拟机中Linux+Oracle10gRAC安装

Vmware软件的安装过程不详述，因为很简单，只要按照提示一步步往下走就ok。在这里提醒一句，如果要配置Oracle RAC，一定不要安装vmware workstation版本，而要安装vmware server版本，这样在创建共享磁盘过程的时候才会比较顺畅。如果是非ORACLE RAC实验环境，这个就无所谓了。下面来到具体的过程：

详细可以参考这个，有图解教程，希望可以帮到你

⑷ linux下安装rac配置网卡的问题

bridge就是用和主机一个地址段的，比如你主机是192.168.1.101，那就随便在这个段找四个没有人用的ip给它。
host-only作心跳线用，不知道你用的是什么宿主虚拟机，比如qemu的默认是192.168.122.1，如果你的宿主是win下面的vmware或者vbox，记不清楚了，可以去查看网络连接里面的对应host-only那个连接，比如192.168.33.1，你就配两个和这同一个网段的地址然后试一下能不能ping通主机和ping通对方。
如果这样说还搞不明白建议先学学网络基础知识

⑸ linux上安装RAC时不使用asmlib的多路径怎么配置

FYI

/dev/mapper/mpathXX


如果使用了 多路径方案， 可以直接使用multipath 绑定设备名 不需要用到 asmlib或UDEV

请直接参考 文档：Configuring non-raw multipath devices for Oracle Clusterware 11g (11.1.0, 11.2.0) on RHEL5/OL5 [ID 605828.1]
