安裝oracle11gR2單實例+ASM，讓新手走向數據庫管理員
一、介紹
因業務需要，最近在主系統的基礎上搭建一套mini系統，本文只講ORACLE數據庫+ASM磁盤管理工具的安裝；
1.服務器系統版本：RHEL5.5x64Bit，kernel2.6.18-194.el5
2.磁盤分區格式：LVM+裸設備
3.ORACLE軟件版本：p10404530_112030_Linux-x86-64
4.ASM組件版本：oracleasm-2.6.18-194.el5-2.0.5-1.el5.x86_64.rpm
oracleasmlib-2.0.4-1.el5.x86_64.rpm
oracleasm-support-2.1.7-1.el5.x86_64.rpm
二、安裝實施準備
1.創建ORACLE用戶和組成員
groupadd oinstall
groupadd dba
groupadd oper
groupadd asmadmin
groupadd asmdba
groupadd asmoper
useradd -g oinstall -G dba,asmdba,oper -d /home/oracle oracle
useradd -g oinstall -G dba,asmadmin,asmdba,asmoper -d /home/grid grid
2.分別創建oracle、grid用戶的密碼
passwd oracle
new unix password:oracle
passwd grid
new unix password:grid
3.磁盤分區
//介紹：本文爲項目簡化，實際項目磁盤分區爲：8塊300G15KSAS磁盤（HP388/G82U服務器最多支持8塊）；
//前2塊做raid1,安裝系統包括：/、sawp、boot分區等，可冗餘磁盤爲:1塊；
//後6塊做raid5,/u0140GLVM管理安裝oracle軟件，/u02450GLVM管理，存放arch和RMAN備份等，可冗餘磁盤爲:1塊；
//ASM磁盤組爲300G*3，DATA1、DATA2、DATA3存放oracle數據；
//本文分區如下：/u0110G,/u0220G,ASM10G*3DATA1、DATA2、DATA3等；

chown -R oracle:oinstall /u01/app/oracle
chown -R oracle:oinstall /u02
chmod -R 775 /u01
chmod -R 775 /u02
4.使用oracle用戶登陸，設置oracle用戶的環境變量
//增加以下幾行
[oracle@ctp-dbserver~]$vim .bash_profile
export ORACLE_SID=zxxj
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:.
export NLS_LANG=American_america.ZHS16GBK
export PATH=$PATH:$ORACLE_HOME/bin:.
5.使用grid域名登陸，設置grid用戶的環境變量
//增加以下幾行
[grid@ctp-dbserver~]$vim .bash_profile
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/11.2.0/grid
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:.
export NLS_LANG=American_america.ZHS16GBK
export PATH=$PATH:$ORACLE_HOME/bin:.
export ORACLE_SID=+ASM
6.使用root更改以下幾項參數
//具體值要根據實際硬件設置，本參數則先按照原服務器CPU：2顆*8核、32G內存、32Gsawp的配置，如有錯誤後面再更正；
[root@ctp-dbserver~]#vim /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 4294967295
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
//該參數的大小和物理內存以及在安裝oracle的時候SGA佔物理內存的40%時的數據直接涉及到sga_max_size的參數的大小。如果設置不恰當很可能導致oracle啓動失敗，或者在手動：
alter system set sga_max_size = **G scope=spfile;
執行/sbin/sysctl-p使設置立即生效
#sysctl -p
7.修改文件數和安全設置
#vim /etc/security/limits.conf
//增加以下內容
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
grid soft stack 10240
8.增加session連接限制庫
#vim /etc/pam.d/login
//增加以下內容
session required /lib/security/pam_limits.so
9.修改hosts文件和主機名
#vim /etc/hosts
192.168.1.10ctp-dbserver
#vim /etc/sysconfig/network
//修改HOSTNAME，使其永久生效
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=ctp-dbserver
GATEWAY=192.168.1.1
10.將必要的安裝文件上傳至服務器
如:
//oracle用戶安裝軟件，存放/u02下
p10404530_112030_Linux-x86-64_1of7.zip
p10404530_112030_Linux-x86-64_2of7.zip
p10404530_112030_Linux-x86-64_3of7.zip
//ASM使用的3個rpm包存放/root下
oracleasm-2.6.18-194.el5-2.0.5-1.el5.x86_64.rpm
oracleasmlib-2.0.4-1.el5.x86_64.rpm
oracleasm-support-2.1.7-1.el5.x86_64.rpm
//依賴的rpm包存放/root下，按照實際系統配置決定，有的包已經安裝；

numactl-devel-0.9.8.x86_64
sysstat-7.0.2
//可先rpm-qa|grep查找是否有缺失未安裝的rpm包
#rpm -ivh *.rpm
三、安裝oralce和ASM組件
1.安裝ASM
//說明：asm組件的安裝需要3個asmrpm包的支持，oracleasmrpm需要和linux系統的內核對應
#uname -ar
2.6.18-194.el5
//oracleasm包要求：
oracleasm-2.6.18-194.el5-2.0.5-1.el5.x86_64.rpm//此包必須和linuxkernel一致
oracleasmlib-2.0.4-1.el5.x86_64.rpm//此包根據要官網說明
oracleasm-support-2.1.7-1.el5.x86_64.rpm//此包根據要官網說明
//參考：下載地址
http://www.oracle.com/technetwork/server-storage/linux/downloads/rhel5-084877.html#oracleasm_rhel5_amd64
[root@ctp-dbserver~]#rpm -ivh *.rpm

2.配置ASM
root用戶登錄，（本次安裝爲單實例），執行：
[root@ctp-dbserver~]#/etc/init.d/oracleasm configure

4.配置xmanager遠程連接RHEL5.5
//修改配置defaults.conf文件
//如果只有oralce和grid圖形登錄只改以下2項即可
#vim /usr/share/gdm/defaults.conf
Enable=true
Port=177
//root登錄，還需要
AllowRoot=true
AllowRemoteRoot=root
//修改inittab必須爲5級別
#vim /etc/inittab
id:5:initdefault:
//重啓gdm
#gdm-restart
//一切OK
5.安裝grid組件
//使用XmanagerEnterprise3的Xbrowser圖形連接服務器
//圖形界面grid用戶登錄，進入/u02/
#unzip p10404530_112030_Linux-x86-64_3of7.zip
#cd grid

【20130725】注：該項參數務必配置正確，否則影響數據庫使用。
9.oracle單實例+ASM的監聽
安裝好grid後，無論是管理磁盤、磁盤數據、oralce啓動與停止、監聽等均可由grid來操作；
使用grid用戶netca創建監聽

五、數據庫備份
因爲ASM管理的數據直接存儲在磁盤上，日常備份一般採用RMAN備份，寒楓後續會介紹oracle11gR2數據庫之RMAN備份。

近期忙於項目，博客已經近半年沒有更新了，最近幾個月由項目選型到方案設計，由招標文件起草到服務器選型，由服務器進場到系統部署，一步步妥而穩的進行，一天天忙而不乏的學習。終於項目定於11月5日上線，我們執着，我們堅信，我們務實，我們謹慎，預祝項目順利上線。
寒楓最近太忙了，OCP在忙碌的過程中已經首戰告捷，接下來就是沉澱數據管理工作實際經驗，當然保證數據的安全是每個數據庫管理員的第一個職責。
業餘時間，寒楓仍然繼續學習oracle這個神聖的機器，讓我們學習的思想像DBMS一樣有條不絮的運轉，未來的道路也漸行漸遠。
