二、RAC      安装前期配置

1、配置/etc/host文件(rac1、rac2上执行)

127.0.0.1   localhost

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

 

#rac1

192.168.100.11                    rac1

192.168.100.13                    rac1-vip

192.168.10.11                     rac1-priv

 

#rac2

192.168.100.12                    rac2

192.168.100.14                    rac2-vip

192.168.10.12                     rac2-priv

 

#scan-ip

192.168.100.10                    scan-cluster

2、配置DNS服务器,解析scan ip(rhel5.8上执行)

1)安装dns包

[root@localhost mnt]# ll

total 1112

-rw-r--r-- 1 root root 1012559 Jan 22 11:11 bind-9.3.6-20.P1.el5.x86_64.rpm

-rw-r--r-- 1 root root   47941 Jan 22 11:14 bind-chroot-9.3.6-20.P1.el5.x86_64.rpm

-rw-r--r-- 1 root root   64667 Jan 22 11:11 caching-nameserver-9.3.6-20.P1.el5.x86_64.rpm

[root@localhost mnt]# rpm -ivh bind-9.3.6-20.P1.el5.x86_64.rpm

[root@localhost mnt]# rpm -ivh bind-chroot-9.3.6-20.P1.el5.x86_64.rpm

[root@localhost mnt]# rpm -ivh caching-nameserver-9.3.6-20.P1.el5.x86_64.rpm

2)配置named.conf文件

         生成named.conf文件:

[root@localhost mnt]# cd /var/named/chroot/etc/

[root@localhost etc]# ll

total 24

-rw-r--r-- 1 root root  3519 Feb 27  2006 localtime

-rw-r----- 1 root named 1230 Dec  2  2011 named.caching-nameserver.conf

-rw-r----- 1 root named  955 Dec  2  2011 named.rfc1912.zones

-rw-r----- 1 root named  113 Jan 22 10:51 rndc.key

[root@localhost etc]# cp -p named.caching-nameserver.conf named.conf

[root@localhost etc]# ll

total 28

-rw-r--r-- 1 root root  3519 Feb 27  2006 localtime

-rw-r----- 1 root named 1230 Dec  2  2011 named.caching-nameserver.conf

-rw-r----- 1 root named 1230 Dec  2  2011 named.conf

-rw-r----- 1 root named  955 Dec  2  2011 named.rfc1912.zones

-rw-r----- 1 root named  113 Jan 22 10:51 rndc.key

         配置named.conf文件:

[root@localhost etc]# vim named.conf

将127.0.0.1和localhost全部改成any。

3)配置named.rfc1912.zones文件

[root@localhost etc]# vim named.rfc1912.zones --在最后添加下面内容

zone "100.168.192.in-addr.arpa" IN {

        type master;

        file "100.168.192.in-addr.arpa";

        allow-update { none; };

};

4)生成正反向解析数据库文件

[root@localhost named]# pwd

/var/named/chroot/var/named

[root@localhost named]# ll

total 44

drwxrwx--- 2 named named 4096 Aug 26  2004 data

-rw-r----- 1 root  named  198 Dec  2  2011 localdomain.zone

-rw-r----- 1 root  named  195 Dec  2  2011 localhost.zone

-rw-r----- 1 root  named  427 Dec  2  2011 named.broadcast

-rw-r----- 1 root  named 1892 Dec  2  2011 named.ca

-rw-r----- 1 root  named  424 Dec  2  2011 named.ip6.local

-rw-r----- 1 root  named  426 Dec  2  2011 named.local

-rw-r----- 1 root  named  427 Dec  2  2011 named.zero

drwxrwx--- 2 named named 4096 Jul 27  2004 slaves

[root@localhost named]# cp -p named.local 100.168.192.in-addr.arpa

[root@localhost named]# ll

total 48

-rw-r----- 1 root  named  426 Dec  2  2011 100.168.192.in-addr.arpa

drwxrwx--- 2 named named 4096 Aug 26  2004 data

-rw-r----- 1 root  named  198 Dec  2  2011 localdomain.zone

-rw-r----- 1 root  named  195 Dec  2  2011 localhost.zone

-rw-r----- 1 root  named  427 Dec  2  2011 named.broadcast

-rw-r----- 1 root  named 1892 Dec  2  2011 named.ca

-rw-r----- 1 root  named  424 Dec  2  2011 named.ip6.local

-rw-r----- 1 root  named  426 Dec  2  2011 named.local

-rw-r----- 1 root  named  427 Dec  2  2011 named.zero

drwxrwx--- 2 named named 4096 Jul 27  2004 slaves

5)配置正向解析数剧库文件

[root@localhost named]# vim localdomain.zone

[root@localhost named]# cat localdomain.zone

$TTL          86400

@              IN SOA      localhost root (

                                               42              ; serial (d. adams)

                                               3H             ; refresh

                                               15M          ; retry

                                               1W            ; expiry

                                               1D )           ; minimum

                 IN NS                  localhost

localhost  IN A           127.0.0.1

scan-cluster    IN A            192.168.100.10             

6)配置反向解析数据库文件

[root@localhost named]# vim 100.168.192.in-addr.arpa

[root@localhost named]# cat 100.168.192.in-addr.arpa

$TTL          86400

@       IN      SOA     localhost. root.localhost.  (

                                      1997022700 ; Serial

                                      28800      ; Refresh

                                      14400      ; Retry

                                      3600000    ; Expire

                                      86400 )    ; Minimum

        IN      NS      localhost.

1       IN      PTR     localhost.

10      IN      PTR     scan-cluster.localdomain

7)服务器上启动DNS服务器

[root@localhost named]# /etc/init.d/named status

rndc: connect failed: 127.0.0.1#953: connection refused

named is stopped

[root@localhost named]# /etc/init.d/named start

Starting named:                                            [  OK  ]

8)配置/etc/resolv.conf文件(rac1、rac2上执行)

[root@rac1 ~]# vim /etc/resolv.conf

 [root@rac1 ~]# cat /etc/resolv.conf

# Generated by NetworkManager

search localdomain

# No nameservers found; try putting DNS servers into your

# ifcfg files in /etc/sysconfig/network-scripts like so:

#

# DNS1=xxx.xxx.xxx.xxx

# DNS2=xxx.xxx.xxx.xxx

# DOMAIN=lab.foo.com bar.foo.com

nameserver 192.168.100.9

9)nslookup检查(rac1、rac2上检验)

[root@rac1 ~]# nslookup 192.168.100.10

Server:               192.168.100.9

Address:  192.168.100.9#53

10.100.168.192.in-addr.arpa  name = scan-cluster.localdomain

 

[root@rac1 ~]# nslookup scan-cluster

Server:               192.168.100.9

Address:  192.168.100.9#53

Name:      scan-cluster.localdomain

Address: 192.168.100.10

3、建组、用户、环境变量、内核参数等(rac1、rac2上执行)

4、停止NTP服务(rac1、rac2上执行)

[root@rac2 mnt]# service ntpd status

ntpd is stopped

[root@rac2 mnt]# chkconfig ntpd off

[root@rac2 mnt]# cp /etc/ntp.conf /etc/ntp.conf.bak

[root@rac2 mnt]# rm /etc/ntp.conf -rf

5、配置grid用户和oracle用户ssh对等性

[root@rac1 mnt]# su - grid

[grid@rac1 ~]$ pwd

/home/grid

[grid@rac1 ~]$ ls -al

total 44

6、配置共享磁盘

1)创建6块共享磁盘并fdisk格式化。

2)安装asm rpm包:

[root@rac2 ~]# cd /mnt

[root@rac2 mnt]# ll

total 136

-rw-r--r--. 1 root root 33956 Jan 22 17:23 kmod-oracleasm-2.0.6.rh1-3.el6.x86_64.rpm

-rw-r--r--. 1 root root 13300 Jan 22 17:23 oracleasmlib-2.0.4-1.el6.x86_64.rpm

-rw-r--r--. 1 root root 74984 Jan 22 17:23 oracleasm-support-2.1.8-1.el6.x86_64.rpm

[root@rac2 mnt]# rpm -qa|grep oracleasm

kmod-oracleasm-2.0.6.rh1-3.el6.x86_64

oracleasmlib-2.0.4-1.el6.x86_64

3)双节点配置asm driver服务

[root@rac1 mnt]# /usr/sbin/oracleasm -h

Usage: oracleasm [--exec-path=<exec_path>] <command> [ <args> ]

       oracleasm --exec-path

       oracleasm -h

       oracleasm -V

The basic oracleasm commands are:

    configure        Configure the Oracle Linux ASMLib driver

    init             Load and initialize the ASMLib driver

    exit             Stop the ASMLib driver

    scandisks        Scan the system for Oracle ASMLib disks

    status           Display the status of the Oracle ASMLib driver

    listdisks        List known Oracle ASMLib disks

    querydisk        Determine if a disk belongs to Oracle ASMlib

    createdisk       Allocate a device for Oracle ASMLib use

    deletedisk       Return a device to the operating system

    renamedisk       Change the label of an Oracle ASMlib disk

    update-driver    Download the latest ASMLib driver

[root@rac1 mnt]# /usr/sbin/oracleasm status

Checking if ASM is loaded: no

Checking if /dev/oracleasm is mounted: no

[root@rac1 mnt]# /usr/sbin/oracleasm configure -i

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 []: grid

Default group to own the driver interface []: asmadmin

Start Oracle ASM library driver on boot (y/n) [n]: y

Scan for Oracle ASM disks on boot (y/n) [y]: y

Writing Oracle ASM library driver configuration: done

[root@rac1 mnt]# /usr/sbin/oracleasm status

Checking if ASM is loaded: no

Checking if /dev/oracleasm is mounted: no

[root@rac1 mnt]# /usr/sbin/oracleasm init

Loading module "oracleasm": oracleasm

Mounting ASMlib driver filesystem: /dev/oracleasm

[root@rac1 mnt]# /usr/sbin/oracleasm status

7、安装grid软件

1)上传安装介质,解压(一个节点即可)。

2)安装grid前预检查(一个节点即可)

[grid@rac1 grid]$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose

3)图形界面安装grid软件

以下图形界面安装略。
