# 12 c rac has an extra grid base directory and needs to prepare a 40 G disk to do GIMR disk, the other is roughly the same.

# start with a question mark full of questions about what rac is. Before you do it, Baidu understands what rac is and what the basic structure is. This is probably what it looks like in the picture below. Baidu is more detailed.

# prepare the oracle installation package and download it on the Oracle official website. The package is free.

1.VMware environment: two virtual machines with linux installed. This time I use red hat 6.8, each with two network cards public/private.

Get some shared disks out.

Cmd changes to the VMware installation directory and performs the creation of a shared disk.

Vmware-vdiskmanager.exe-c-s 1G-a lsilogic-t 2 C:\ share_disk\ ocr01.vmdk

Vmware-vdiskmanager.exe-c-s 1G-a lsilogic-t 2 C:\ share_disk\ ocr02.vmdk

Vmware-vdiskmanager.exe-c-s 1G-a lsilogic-t 2 C:\ share_disk\ ocr03.vmdk

Vmware-vdiskmanager.exe-c-s 5G-a lsilogic-t 2 C:\ share_disk\ data.vmdk

Vmware-vdiskmanager.exe-c-s 5G-a lsilogic-t 2 C:\ share_disk\ backup.vmdk

Change the .vmx file of the virtual machine and add the virtual disk you just created at the end of the file.

Scsi1.present = "TRUE"

Scsi1.virtualDev = "lsilogic"

Scsi1.sharedBus = "virtual"

Scsi1:1.present = "TRUE"

Scsi1:1.mode = "independent-persistent"

Scsi1:1.filename = "C:\ share_disk\ ocr01.vmdk"

Scsi1:1.deviceType = "disk"

Scsi1:2.present = "TRUE"

Scsi1:2.mode = "independent-persistent"

Scsi1:2.filename = "C:\ share_disk\ ocr02.vmdk"

Scsi1:2.deviceType = "disk"

Scsi1:3.present = "TRUE"

Scsi1:3.mode = "independent-persistent"

Scsi1:3.filename = "C:\ share_disk\ ocr03.vmdk"

Scsi1:3.deviceType = "disk"

Scsi1:4.present = "TRUE"

Scsi1:4.mode = "independent-persistent"

Scsi1:4.filename = "C:\ share_disk\ backup.vmdk"

Scsi1:4.deviceType = "disk"

Scsi1:5.present = "TRUE"

Scsi1:5.mode = "independent-persistent"

Scsi1:5.filename = "C:\ share_disk\ data.vmdk"

Scsi1:5.deviceType = "disk"

Disk.locking = "false"

Disk.EnableUUID = "true"

DiskLib.dataCacheMaxSize = "0"

DiskLib.dataCacheMaxReadAheadSize = "0"

DiskLib.DataCacheMinReadAheadSize = "0"

DiskLib.dataCachePageSize = "4096"

DiskLib.maxUnsyncedWrites = "0"

two。 Power on and check that both hosts can see the shared disk you just added and check the swap space.

3. Operating system configuration

3.1 turn off selinux

3.2 close iptables

5. Upload files, install dependency packages, install grid,oracle database software in graphical interface, and build DBCA database.

5.1 install the dependency package and install it with yum

Yum install-y binutils compat-libstdc++-33 glibc ksh libaio libgcc libstdc++ make compat-libcap1 gcc gcc-c++ glibc-devel libaio-devel libstdc++-devel sysstat elfutils-libelf-devel

5.2 graphical interface grid user runs. / runInstaller

Installation type chooses the senior.

Add rac2 and configure two-node grid user trust

Pay attention to the path selection and select the three ocr disks just now

Finally, the installation check will report the asm disk warning, check that both nodes can access the asm disk and directly ignore the next step.

Dd if=/dev/zero f=/dev/asm-sda bs=1024 count=1

5.3 run the root script after installation, first on the first node, and then sequentially on the other nodes, not at the same time

/ u01/app/oraInventory/orainstRoot.sh

/ u01/11.2.0/grid/root.sh

5.4 verify the cluster

[root@rac1] # / oracle/11.2.0/grid/bin/crs_stat-t

5.5 graphical interface oracle user runs. / runInstaller

Install only database software

Add rac2 and set oracle user trust

5.6 next step until the installation is complete, execute the root script as well

5.7DBCA builds database, graphical interface Oracle user executes dbca

Select rac database

Customization

Select two nodes

Using ASM disk to store data

The later configuration depends on the requirements, and the test environment can all try.
