2024-05-13 12:17:24

基础环境

服务器品牌	IBM
服务器型号	X3650M2
cpu类型	Intel Xeon E5620@ 2.40GHz
cpu个数	2
内存大小	24G
磁盘阵列	DS3200
硬盘大小	1.8TB

软件准备:

--Oracle Database (includes Oracle Database and Oracle RAC)

p10404530_112030_platform_1of7.zip

p10404530_112030_platform_2of7.zip

--Oracle Grid Infrastructure (includes Oracle ASM, Oracle Clusterware, and Oracle Restart)

p10404530_112030_platform_3of7.zip

1配置yum源

vim /etc/yum.repos.d/rhel-debuginfo.repo

ORADB1:

[Server]

name=Server

baseurl=file:///mnt/Server

enabled=1

gpgcheck=0

ORADB2:

[Server]

name=Server

baseurl=ftp://oradb1/pub/Server

enabled=1

gpgcheck=0

2同时检查以下包是否被安装

rpm -q --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n" \

binutils \

compat-libstdc++-33 \

elfutils-libelf \

elfutils-libelf-devel \

gcc \

gcc-c++ \

glibc \

glibc-common \

glibc-devel \

glibc-headers \

ksh \

libaio \

libaio-devel \

libgcc \

libstdc++ \

libstdc++-devel \

make \

sysstat \

unixODBC \

unixODBC-devel

通过检查发现我的系统一下4个包没有安装：

package libaio-devel is not installed

package sysstat is not installed

package unixODBC is not installed

package unixODBC-devel is not installed

package sysstat is not installed

--挂载CD镜像到mnt目录下：

[root@localhost tmp]# mount /dev/cdrom /mnt/

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

--yum安装这几个包

[root@localhost tmp]# yum install libaio-devel package libaio-develunixODBC unixODBC-devel sysstat –y

--yum安装第二个节点的时候可以重新挂载

[root@localhost tmp]# mount /dev/cdrom /var/ftp/pub/

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

3.关掉大部分不用服务(可能因人因环境而异).

chkconfig bluetooth --level 2345 off

chkconfig ip6tables --level 2345 off

chkconfig portmap --level 2345 off

chkconfig sendmail --level 2345 off

chkconfig vsftpd --level 2345 off

chkconfig iptables off

chkconfig ntpd off

4在每一个节点上配置/etc/hosts文件，文件内容如下

# Public Network ? (eth0)

10.0.18.12oradb1.bdstar.com oradb1

10.0.18.13oradb2.bdstar.com oradb2

# Public Virtual IP (VIP) addresses ? (eth0:1)

10.0.18.120oradb1-vip.bdstar.com oradb1-vip

10.0.18.130oradb2-vip.bdstar.com oradb2-vip

# Private Interconnect ? (eth1)

10.10.10.120 oradb1-priv.bdstar.comoradb1-priv

10.10.10.130 oradb2-priv.bdstar.comoradb2-priv

#Compute node Client Access SCAN Interface details

10.0.18.36oradb-scan.bdstar.com oradb-scan

5修改主机名

[root@localhost ~]# vim /etc/sysconfig/network

Oradb1上添加如下：

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME=oradb1.bdstar.com

Oradb2上添加如下：

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME=oradb1.bdstar.com

6配置集群时间同步服务— (CTSS)

--不采用系统上的NTP服务，利用oracle集群的CTSS服务

[root@racnode1 ~]# /sbin/service ntpd stop

[root@racnode1 ~]# chkconfig ntpd off

[root@racnode1 ~]# mv /etc/ntp.conf /etc/ntp.conf.original

还要删除以下文件：

[root@racnode1 ~]# rm /var/run/ntpd.pid

7内核参数的配置

[root@rac1 ~]# cd /etc/

[root@rac1 etc]# sysctl -p

net.ipv4.ip_forward = 0

net.ipv4.conf.default.rp_filter = 1

net.ipv4.conf.default.accept_source_route = 0

kernel.sysrq = 0

kernel.core_uses_pid = 1

net.ipv4.tcp_syncookies = 1

kernel.msgmnb = 65536

kernel.msgmax = 65536

kernel.shmmax = 68719476736

kernel.shmall = 4294967296

net.ipv4.ip_local_port_range = 9000 65500

fs.file-max = 6815744

fs.suid_dumpable = 1

fs.aio-max-nr = 1048576

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048586

8 DNS的配置

只在节点1做一个DNS服务端即可:

[root@localhost etc]# yum install bind bind-chroot caching-nameserver

# vim /var/named/chroot/etc/named.conf

directory "/var/named";

zone "localdomain" in {

file "localdomain.zone";

zone "bdstar.com" IN {

file "bdstar.com.zone";

[root@oradb1 ~]# cd /var/named/chroot/var/named/

[root@oradb1 named]# vim bdstar.com.zone

@IN SOA @ root (

42 ; serial (d. adams)

@ IN NSoradb1.bdstar.com.

oradb1IN A 10.0.18.12

oradb2IN A 10.0.18.13

oradb1-vipIN A 10.0.18.120

oradb2-vipIN A 10.0.18.130

oradb-scanIN A 10.0.18.36

[root@oradb1 named]# vim localdomain.zone

@IN SOA localhost root (

42 ; serial (d. adams)

IN NS localhost

oradb1IN A 10.0.18.12

oradb2IN A 10.0.18.13

oradb1-vipIN A 10.0.18.120

oradb2-vipIN A 10.0.18.130

oradb-scanIN A 10.0.18.36

[root@oradb1 named]# cat /etc/resolv.conf

nameserver 10.0.18.12

search localdomain bdstar.com

[root@oradb1 named]# service named restart

--测试下是否生效

[root@oradb1 named]# nslookup oradb1.bdstar.com

Server:10.0.18.12

Address:10.0.18.12#53

Name:oradb1.bdstar.com

Address: 10.0.18.12

--调整DNS解析

由于oracle强烈建议不要见scan放入到hosts中，这样做的结果是只能有一个SCAN的IP被使用。所以我们调整解析的顺序：

[root@oradb1 log]# vim /etc/nsswitch.conf

hosts:dns files

[root@oradb1 ~]# /sbin/service nscd restart

9创建grid和oracle用户，在每一个节点操作

groupadd -g 1000 oinstall

groupadd -g 1020 asmadmin

groupadd -g 1021 asmdba

groupadd -g 1022 asmoper

groupadd -g 1300 dba

useradd -u 1101 -g oinstall -G dba,asmdba -c "Oracle Software Owner" oracle

useradd -u 1100 -g oinstall -G asmadmin,asmdba,asmoper,dba -c "Grid Infrastructure Owner" grid

--修改oracle grid密码

10创建oracle和grid的Oracle Base 目录

mkdir -p/u01/app/11.2.0/grid

mkdir -p /u01/app/grid

chown -R grid:oinstall /u01

mkdir -p /u01/app/oracle

chown oracle:oinstall /u01/app/oracle

chmod -R 775 /u01

-- Oracle Inventory Directory

mkdir -p /u01/app/oraInventory

chown -R grid:oinstall /u01/app/oraInventory

chmod -R 755 /u01/app/oraInventory

11配制grid,oracle用户环境变量

节点1grid用户：

~/.bash_profile增加以下内容

export ORACLE_BASE=/u01/app/grid

export ORACLE_HOME=/u01/app/11.2.0/grid

export PATH=$PATH:$ORACLE_HOME/bin

export NLS_LANG="SIMPLIFIED CHINESE_CHINA".AL32UTF8

export ORACLE_SID=+ASM1

节点2grid用户：

~/.bash_profile增加以下内容

export ORACLE_BASE=/u01/app/grid

export ORACLE_HOME=/u01/app/11.2.0/grid

export PATH=$PATH:$ORACLE_HOME/bin

export NLS_LANG="SIMPLIFIED CHINESE_CHINA".AL32UTF8

export ORACLE_SID=+ASM2

节点1 ORACLE用户:

~/.bash_profile增加以下内容

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1

export PATH=$PATH:$ORACLE_HOME/bin

export NLS_LANG="SIMPLIFIED CHINESE_CHINA".AL32UTF8

export ORACLE_SID=bdspoc1

节点2 ORACLE用户:

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1

export PATH=$PATH:$ORACLE_HOME/bin

export NLS_LANG="SIMPLIFIED CHINESE_CHINA".AL32UTF8

export ORACLE_SID=bdspoc2

12设置用户资源限制

1.在文件 /etc/security/limits.conf加以下参数:

#Install oracle setting

oraclesoft nproc 2047

oraclehard nproc 16384

oraclesoft nofile 1024

oraclehard nofile 65536

oraclesoft stack 10240

gridsoft nproc 2047

gridhard nproc 16384

gridsoft nofile1024

gridhard nofile 65536

gridsoft stack 10240

增加如下行在/etc/pam.d/login文件中

sessionrequired pam_limits.so

vim /etc/profile

if [ $USER = "oracle" ] || [ $USER = "grid" ]; then

if [ $SHELL = "/bin/ksh" ]; then

ulimit -p 16384

ulimit -n 65536

ulimit -u 16384 -n 65536

For the C shell (csh or tcsh), add the following lines to the /etc/csh.login file:

if ( $USER = "oracle" || $USER = "grid" ) then

limit maxproc 16384

limit descriptors 65536

13设置RDAC

由于用的是IBM的磁盘阵列，所以需要在系统端安装多路径软件。

下载地址：http://support.netapp.com/NOW/public/apbu/oemcp/

将下载的RDAC包解压生成linuxrdac-09.03.0C05.0638文件夹

进入文件夹后编译该包，

[root@oradb1 linuxrdac-09.03.0C05.0638]# make

make[1]: Entering directory `/usr/src/kernels/2.6.18-274.el5-x86_64'

gcc mppUtil.o mppUtilSysdep.o -o mppUtil

gcc -o genuniqueid genuniqueid.c

[root@oradb1 linuxrdac-09.03.0C05.0638]# make install

make[1]: Entering directory `/tmp/linuxrdac-09.03.0C05.0638'

MPP driver package has been successfully installed on your system.

--在/boot文件夹下生成一个mpp的文件

[root@oradb1 boot]# pwd

[root@oradb1 boot]# ls

initrd-2.6.18-274.el5.imgmpp-2.6.18-274.el5.img vmlinuz-2.6.18-274.el5

--修改启动选项

[root@oradb1 tmp]# vim /boot/grub/menu.lst

splashimage=(hd0,0)/grub/splash.xpm.gz

title Red Hat Enterprise Linux Server (2.6.18-274.el5)

initrd /initrd-2.6.18-274.el5.img

title Red Hat Enterprise Linux Server with MPP surpport

kernel /vmlinuz-2.6.18-274.el5 ro root=LABEL=/ rhgb quiet

initrd /mpp-2.6.18-274.el5.img

节点2做同样的事

14共享磁盘分区

[root@oradb1 ~]# fdisk /dev/sdc

The number of cylinders for this disk is set to 72815.

There is nothing wrong with that, but this is larger than 1024,

and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs

(e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): n

p primary partition (1-4)

Partition number (1-4): 1

First cylinder (1-72815, default 1):

Using default value 1

Last cylinder or +size or +sizeM or +sizeK (1-72815, default 72815): +1024M

Command (m for help): n

p primary partition (1-4)

Partition number (1-4): 2

First cylinder (126-72815, default 126):

Using default value 126

Last cylinder or +size or +sizeM or +sizeK (126-72815, default 72815):

Using default value 72815

Command (m for help): w

The partition table has been altered!

Calling ioctl() to re-read partition table.

[root@oradb1 ~]# /sbin/partprobe

在节点2查看共享磁盘情况，OK！和1节点的一直。

15 asmlib包的安装

下载：http://www.oracle.com/technetwork/server-storage/linux/downloads/rhel5-084877.html
