介紹reahat as 4 下cluster 的應用

[@more@]

DL 560作為Web伺服器接受使用者各類連線請求並對外進行相應資訊釋出；兩臺DL 580作為資料庫伺服器接受所有Web伺服器轉發而來的所有資料連線請求並做相應的資料處理。為保證系統的高可靠性及高擴充套件性，在兩臺DL 580之間構建叢集，後端則透過光纖連至MSA 1000高效能光纖陣列櫃，由光纖陣列櫃提供具體的資料儲存操作。

2 第二章 資料庫伺服器配置

2.1 redhat linux AS 4.0 安裝

1) 安裝Redhat AS4

關閉MSA1000, 分別在兩臺伺服器下安裝Redhat EL AS4，安裝完之後，看dmesg，發現AS4已經能夠把伺服器上的HBA FCA2214驅動起來

2）安裝驅動

分別在兩臺伺服器上安裝SmartStart CD中的PSP包，在/compaq/csp/linux

3）下載Linux AS4.0 對應的update2 ,並安裝

4) 升級linux,安裝以下升級包

rpm -ivh freetype-devel-2.1.9-1.i386.rpm

rpm -ivh fontconfig-devel-2.2.3-7.i386.rpm

rpm -ivh xorg-x11-devel-6.8.2-1.EL.13.20.i386.rpm

rpm -ivh libjpeg-devel-6b-33.i386.rpm

rpm -ivh libtiff-devel-3.6.1-8.i386.rpm

rpm -ivh libungif-devel-4.1.3-1.i386.rpm

rpm -ivh alsa-lib-devel-1.0.6-5.RHEL4.i386.rpm

rpm -ivh audiofile-devel-0.2.6-1.i386.rpm

rpm -ivh esound-devel-0.2.35-2.i386.rpm

rpm-ivhg-x11-deprecated-libs-devel-6.8.2-1.EL.13.20.i38

rpm -ivh libaio-devel-0.3.103-3.i386.rpm

rpm -ivh nss_db-compat-2.2-29.i386.rpm

rpm -ivh glib-devel-1.2.10-15.i386.rpm

rpm -ivh gtk+-devel-1.2.10-33.i386.rpm

rpm -ivh imlib-devel-1.9.13-23.i386.rpm

rpm -ivh ORBit-devel-0.5.17-14.i386.rpm

rpm -ivh gnome-libs-devel-1.4.1.2.90-44.1.i386.rpm

5) Oracle相容包(p4198954_40_LINUX.zip

rpm -ivh compat-libcwait-2.1-1.i386.rpm

rpm -ivh compat-oracle-rhel4-1.0-5.i386.rpm

6) 建立使用者及帳號

groupadd oinstall

groupadd dba

useradd -m -g oinstall -G dba oracle

passwd oracle

7) 配置Linux的核心引數

[root@srv /]# vi ／etc/sysctl.conf

# Created by Stone

kernel.shmmax = 1073741824

kernel.shmmni = 4096

kernel.shmall = 2097152

kernel.sem = 250 32000 100 128

fs.file-max = 65536

net.ipv4.ip_local_port_range = 1024 6500

[root@srv /]# sysctl -p

8) 設定Oracle對檔案的要求

[root@srv /]# vi /etc/security/limits.conf

# Created by Stone

oracle soft memlock 3145728

oracle hard memlock 3145728

9) 準備Oracle安裝目錄

[root@srv /]# mkdir -p /home/oracle/product/9.2.0

[root@srv /]# chown -R oracle:dba /home/oracle

# 安裝時orainstRoot.sh生成及執行處

[root@srv /]# mkdir /var/opt/oracle

[root@srv /]# chown -R oracle.dba /var/opt/oracle

Creating Oracle Inventory pointer file (/etc/oraInst.loc)

Changing groupname of /home/oracle/oraInventory to oinstall.

10)設定Oracle使用者的環境變數

[root@srv /]# vi /home/oracle/.bash_profile

# export PATH

# unset USERNAME

# Created by Stone

# export LD_ASSUME_KERNEL=2.4.1

export LD_ASSUME_KERNEL=2.4.19

# export DISPLAY=192.168.1.251:0.0

# export JAVA_HOME=/usr/local/java

export ORACLE_BASE=/home/oracle

export ORACLE_HOME=$ORACLE_BASE/product/9.2.0

export ORACLE_SID=codora

export ORACLE_TERM=xterm

export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK

export ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:/lib:/usr/lib:usr/local/lib

export PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch

CLASSPATH=$ORACLE_HOME/jre:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlib

export CLASSPATH

export LANG=en_US

export DBCA_RAW_CONFIG=$ORACLE_BASE/DBCA_RAW_CONFIG

unset USERNAME

2.2 oracle 資料庫的安裝及配置

1) oracle 的安裝

root@srv /]# su - oracle

[root@srv /]# /xxx/Disk1/runInstaller

/home/oracle/product/9.2.0/root.sh

Running Oracle9 root.sh script...

nThe following environment variables are set as:

ORACLE_OWNER= oracle

ORACLE_HOME= /home/oracle/product/9.2.0

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 ...

nCreating /etc/oratab file...

Adding entry to /etc/oratab file...

Entries will be added to the /etc/oratab file as needed by

Database Configuration Assistant when a database is created

Finished running generic part of root.sh script.

Now product-specific root actions will be performed.

2) Oracle補丁安裝

[root@srv /]# unzip p4188455_10103_linux.zip

[root@srv /]# unzip p4163445_92070_LINUX.zip

[oracle@srv /unzip]# 4163445/Disk1/runInstaller -paramfile 4188455/oraparam.ini

[root@coddb1 ~]# /home/oracle/product/9.2.0/root.sh

Running Oracle9 root.sh script...

nThe following environment variables are set as:

ORACLE_OWNER= oracle

ORACLE_HOME= /home/oracle/product/9.2.0

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

The file "dbhome" already exists in /usr/local/bin. Overwrite it? (y/n)

[n]: y

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

Entries will be added to the /etc/oratab file as needed by

Database Configuration Assistant when a database is created

Finished running generic part of root.sh script.

Now product-specific root actions will be performed.

2.3 磁碟陣列櫃MSA1000的配置

1)建立物理卷

[root@srv /]# fdisk /dev/sdc

[root@srv /]# pvcreate /dev/sdc

建立邏輯卷組

/dev/raw/raw21 /dev/sdb8 #redo01_2

/dev/raw/raw22 /dev/sdb9 #redo02_2

/dev/raw/raw23 /dev/sdb10 #redo03_2

4)修改裸裝置屬主

[root@srv /]# service rawdevices restart

5)修改裸裝置屬主

[root@srv /]# vi /etc/rc.local

# Created by Stone

chown oracle:oinstall /dev/raw/raw1

2.4 redhat linux cluster 配置

1)redhat 官方網站下cluster 2.1

2)cluster 啟動oralce

編寫orad.ora
