Oracle Tutorial: manually add the third node of RAC

Part 1 Preparation and installation of clusterware and Oracle software

1. IP address planning

	Node1	Node2	Node3
Hostname	Rac1	Rac2	Rac3
Public IP	192.168.5.243	192.168.5.244	192.168.5.239
Private IP	10.0.0. 1	10.0.0. 2	10.0.0. 3
VIP	192.168.5.246	192.168.5.247	192.168.5.240

 

2. Install Node 3. Configure the operating system according to the method of installing the first two nodes.

Including the user group Oracle and dba, related installation directory creation,/home/oracle/. bash_profile add

Test dependency packages

Configure/etc/sysconfig/sysctl. conf,/etc/limits. conf

Configure Time Synchronization

Configure hangcheck_timer

Install and configure Oracle asmlib and search for the asm disks created on the first two nodes.

3. Network Authentication Configuration

Modify the/etc/hosts of the three nodes as follows:

127.0.0.1 localhost
# Rac1
192.168.5.243 rac1
10.0.0.1 rac1-priv
192.168.5.246 rac1-vip
~
# Rac2
192.168.5.244 rac2
Rac2-priv 10.0.0.2
192.168.5.247 rac2-vip

# Rac3
192.168.5.239 rac3
Rac3-priv 10.0.0.3
The 192.168.5.240 rac3-vip

Configure three nodes for authentication and pass the test

4. In Node 1, use addnode. sh to install the clusterware software and CRS service on node rac3.

1) Use the cluvfy/runcluvfy. sh script in the clusterware installation directory for verification.

[Oracle @ rac1 ~] $/Home/oracle/clusterware/cluvfy/runcluvfy. sh stage-pre crsinst-n rac3-verbose

2) [oracle @ rac1 ~] $ ORA_CRS_HOME/oui/bin/addNode. sh

Go to the terware installation page

Finally, the system will prompt you to execute scripts on rac3, rac1, and rac3.

Then complete the clusterware Software Installation

3) register the ONS service of the new node to OCR.

[Oracle @ rac1 ~] $ ORA_CRS_HOME/bin/racgons add_config racing 3: 6200

4) Check the installation result

[Oracle @ rac1 ~] $ ORA_CRS_HOME/cluvfy stage-post crsinst-n rac3-verbose

Successful is displayed.

5. Install Oracle software

Run $ ORACLE_HOME/oui/bin/addNode. sh on node 1 and run the script on rac3.
