RedHat6.5 install Oracle 12C RAC

12c RAC Installation Process

Note: The following configurations are executed on both nodes.

1. Network Configuration

Take rac01 as an example. Both nodes must be configured.

Eth0 and eth1 are bond0

Eth2 and eth3 are bond1

The Mac address record is as follows:

Eth0: 00: 0C: 29: 12: 28: 2C

Eth1: 00: 0c: 29: 12: 28: 36

Eth2: 00: 0c: 29: 12: 28: 40

Eth3: 00: 0c: 29: 12: 28: 4a

2. kernel module Loading

[Root @ rac01 ~] # Vi/etc/modprobe. d/dist. conf

Add content

Alias bond0 bonding

Alias bond1 bonding

Alias scsi_hostadapter2 lpfc

[Root @ rac01 ~] # Vi/etc/modprobe. d/openfwwf. conf

Add content

Options lpfc lpfc_nodev_tmo = 30 lpfc_lun_queue_depth = 16 lpfc_discovery_threads = 32

Options hangcheck-timer hangcheck_tick = 1 hangcheck_margin = 10 hangcheck_reboot = 1

Options e1000 FlowControl = 1

3. Disable the sendmail service.

[Root @ test-rac01 ~] # Chkconfig sendmail off

[Root @ test-rac01 ~] # Chkconfig -- list | grep sendmail

Sendmail 0: off 1: off 2: off 3: off 4: off 5: off 6: off

4. Configure the hosts file and DNS

[Root @ test-rac01 ~] # Cat/etc/hosts

# Do not remove the following line, or various programs

# That require network functionality will fail.

12 7.0.0.1 test-rac01 localhost. localdomain localhost

: 1 localhost6.localdomain6 localhost6

# Public IP for Oracle 11g RAC

10.109.67.52 rac01.localdomain rac01

10.109.67.53 rac02.localdomain rac02

 

# Private IP for Oracle 11g RAC

193.168.1.102 rac01pri. localdomain rac01pri

193.168.1.103 rac02pri. localdomain rac02pri

 

# Virtual IP for Oracle 11g RAC

10.109.67.46 rac01vip. localdomain rac01vip

10.109.67.47 rac02vip. localdomain rac02vip

 

Ensure that the two nodes can communicate with each other using the host

Configure DNS
