【Oracle】RAC添加新节点

RAC添加节点：

环境：

OS：OEL5.6

RAC：10.2.0.1.0

原有rac1,rac2两个节点。如今要添加rac3节点：

操作过程：

改动三个节点上的/etc/hosts文件

192.168.90.2 rac1

192.168.90.5 rac2

192.168.90.6 rac3

192.168.91.3 rac1-priv

192.168.91.6 rac2-priv

192.168.91.7 rac3-priv

192.168.90.3 rac1-vip

192.168.90.4 rac2-vip

192.168.90.7 rac3-vip

rac3节点上安装须要的rpm包，本实验环境使用的是OEL系统，所以使用oracle-validated。

[root@rac3 ~]# mount /dev/cdrom /mnt

mount: block device /dev/cdrom is write-protected, mounting read-only

[root@rac3 ~]# vi /etc/yum.repos.d/public-yum-el5.repo

[oel5]

name = Enterprise Linux 5.6 DVD

baseurl=file:///mnt/Server/

gpgcheck=0

enabled=1

[root@rac3 ~]# yum install oracle-validated

Loaded plugins: rhnplugin, security

This system is not registered with ULN.

ULN support will be disabled.

......略

安装ASMLib包：

[root@rac3 ~]# cd /mnt/Server

[root@rac3 Server]# rpm -ivh oracleasm-support-2.1.4-1.el5.i386.rpm

warning: oracleasm-support-2.1.4-1.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 1e5e0159

Preparing... ########################################### [100%]

1:oracleasm-support ########################################### [100%]

[root@rac3 Server]# rpm -ivh oracleasm-2.6.18-238.el5-2.0.5-1.el5.i686.rpm

warning: oracleasm-2.6.18-238.el5-2.0.5-1.el5.i686.rpm: Header V3 DSA signature: NOKEY, key ID 1e5e0159

Preparing... ########################################### [100%]

1:oracleasm-2.6.18-238.el########################################### [100%]

配置3节点和1,2节点间的互信：

3节点：

[oracle@rac3 ~]$ ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/home/oracle/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /home/oracle/.ssh/id_rsa.

Your public key has been saved in /home/oracle/.ssh/id_rsa.pub.

The key fingerprint is:

18:d5:6a:94:4c:12:90:8a:19:ca:96:4d:97:cc:fe:f0 oracle@rac3

1节点：

[oracle@rac1 .ssh]$ ssh 192.168.90.6 cat ~/.ssh/*.pub >> authorized_keys

oracle@192.168.90.6's password:

[oracle@rac1 .ssh]$ scp authorized_keys 192.168.90.6:~/.ssh/.

oracle@192.168.90.6's password:

authorized_keys 100% 1780 1.7KB/s 00:00

[oracle@rac1 .ssh]$ scp authorized_keys 192.168.90.5:~/.ssh/.

authorized_keys 100% 1780 1.7KB/s 00:00

各个节点运行下面脚本測试oracle用户的互信：

ssh rac1 date

ssh rac2 date

ssh rac3 date

ssh rac1-priv date

ssh rac2-priv date

ssh rac3-priv date

配置时间同步：

[root@rac3 Server]# ntpdate 192.168.90.2

22 Aug 10:45:31 ntpdate[9511]: adjust time server 192.168.90.2 offset -0.109663 sec

[root@rac3 Server]# crontab -e

* * * * * /usr/sbin/ntpdate 192.168.90.2 >> /ntp.log

因为使用的是openfiler作为存储，这里加入openfiler配置过程：









然后到rac3节点上配置：

[root@rac3 ~]# vi /etc/iscsi/initiatorname.iscsi

#InitiatorName=iqn.1988-12.com.oracle:48354521e5f2

InitiatorName=rac3

[root@rac3 ~]# iscsiadm -m discovery -t st -p 192.168.90.8

192.168.90.8:3260,1 rac3

[root@rac3 ~]# service iscsi restart

Stopping iSCSI daemon:

iscsid is stopped [ OK ]

Starting iSCSI daemon: [ OK ]

[ OK ]

Setting up iSCSI targets: Logging in to [iface: default, target: rac3, portal: 192.168.90.8,3260]

Login to [iface: default, target: rac3, portal: 192.168.90.8,3260] successful.

[ OK ]

然后看一下磁盘是否挂载成功：

[root@rac3 ~]# fdisk -l

挂载成功之后。配置设备固定化：

[root@rac3 ~]# raw /dev/raw/raw1 /dev/sdb1

/dev/raw/raw1: bound to major 8, minor 17

[root@rac3 ~]# raw /dev/raw/raw2 /dev/sdc1

Configuring the Oracle ASM library driver.

This will configure the on-boot properties of the Oracle ASM library

driver. The following questions will determine whether the driver is

loaded on boot and what permissions it will have. The current values

will be shown in brackets ('[]'). Hitting <ENTER> without typing an

answer will keep that current value. Ctrl-C will abort.

Default user to own the driver interface []: oracle

Default group to own the driver interface []: dba

rac3节点上创建/u01文件夹，并授予oracle：

rac3节点安装数据库软件：

rac1节点上上使用oracle用户运行$ORACLE_HOME/oui/bin/addNode.sh











[root@rac3 ~]# /u01/app/oracle/product/10.2.0/db_2/root.sh

Running Oracle10 root.sh script...

The following environment variables are set as:

ORACLE_OWNER= oracle

ORACLE_HOME= /u01/app/oracle/product/10.2.0/db_2

Enter the full pathname of the local bin directory: [/usr/local/bin]:

Copying dbhome to /usr/local/bin ...

Copying oraenv to /usr/local/bin ...

Copying coraenv to /usr/local/bin ...

然后在rac1节点上使用dbca加入instance：























至此节点加入完成：

[oracle@rac1 crsd]$ crs_stat -t
