安装oracle 11gR2单实例+ASM

安装oracle11gR2单实例+ASM，让新手走向数据库管理员

1、介绍
因业务须要，最近在主系统的基础上搭建一套mini系统，本文只讲ORACLE数据库+ASM磁盘管理工具的安装；
1.服务器系统版本：RHEL5.5x64Bit，kernel2.6.18-194.el5
2.磁盘分区格式：LVM+裸设备
3.ORACLE软件版本：p10404530_112030_Linux-x86-64
4.ASM组件版本：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
2、安装实施准备
1.建立ORACLE用户和组成员

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.分别建立oracle、grid用户的密码
passwd oracle
new unix password:oracle

passwd grid
new unix password:grid

3.磁盘分区
//介绍：本文为项目简化，实际项目磁盘分区为：8块300G15KSAS磁盘（HP388/G82U服务器最多支持8块）；
//前2块 raid1,安装系统包括：/、sawp、boot分区等，可冗余磁盘为:1块；
//后6块  raid5,/u0140GLVM管理安装oracle软件，/u02450GLVM管理，存放arch和RMAN备份等，可冗余磁盘为:1块；
//ASM磁盘组为300G*3，DATA一、DATA二、DATA3存放oracle数据；
//本文分区以下：/u0110G,/u0220G,ASM10G*3DATA一、DATA二、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用户登录，设置oracle用户的环境变量
//增长如下几行
[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域名登录，设置grid用户的环境变量
//增长如下几行
[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更改如下几项参数
//具体值要根据实际硬件设置，本参数则先按照原服务器CPU：2颗*8核、32G内存、32Gsawp的配置，若有错误后面再更正；
[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

//该参数的大小和物理内存以及在安装oracle的时候SGA占物理内存的40%时的数据直接涉及到sga_max_size的参数的大小。若是设置不恰当极可能致使oracle启动失败，或者在手动：

alter system set sga_max_size = **G scope=spfile;

执行/sbin/sysctl-p使设置当即生效
#sysctl -p

7.修改文件数和安全设置
#vim /etc/security/limits.conf
//增长如下内容
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.增长session链接限制库
#vim /etc/pam.d/login
//增长如下内容
session required /lib/security/pam_limits.so

9.修改hosts文件和主机名
#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.将必要的安装文件上传至服务器
如:
//oracle用户安装软件，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个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
//依赖的rpm包存放/root下，按照实际系统配置决定，有的包已经安装；

//可先rpm-qa|grep查找是否有缺失未安装的rpm包
#rpm -ivh *.rpm

3、安装oralce和ASM组件
1.安装ASM
//说明：asm组件的安装须要3个asmrpm包的支持，oracleasmrpm须要和linux系统的内核对应
#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//此包必须和linuxkernel一致
oracleasmlib-2.0.4-1.el5.x86_64.rpm//此包根据要官网说明
oracleasm-support-2.1.7-1.el5.x86_64.rpm//此包根据要官网说明
//参考：下载地址
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用户登陆，（本次安装为单实例），执行：
[root@ctp-dbserver~]#/etc/init.d/oracleasm configure

4.配置xmanager远程链接RHEL5.5
//修改配置defaults.conf文件
//若是只有oralce和grid图形登陆只改如下2项便可
#vim /usr/share/gdm/defaults.conf
Enable=true
Port=177
//root登陆，还须要
AllowRoot=true
AllowRemoteRoot=root
//修改inittab必须为5级别
#vim /etc/inittab
id:5:initdefault:
//重启gdm
#gdm-restart
//一切OK

5.安装grid组件
//使用XmanagerEnterprise3的Xbrowser图形链接服务器

//图形界面grid用户登陆，进入/u02/

#unzip p10404530_112030_Linux-x86-64_3of7.zip

#cd grid

6.图形界面使用asmca建立ASM磁盘组
$asmca

//注意：若是上述在执行./root.sh后没有执行，/u01/app/11.2.0/grid/crs/install/roothas.pl
//那么将会出现：

7.使用Oracle用户图形下安装oralce软件
[oracle@ctp-dbserver]$cd /u02/
[oracle@ctp-dbserver]$unzip p10404530_112030_Linux-x86-64_1of7.zip

8.建立数据库
//图形界面下使用oracle用户执行dbca
$dbca

//dbca建库介绍
//建立完成后重启服务器

【20130725】注：该项参数务必配置正确，不然影响数据库使用。

9.oracle单实例+ASM的监听
安装好grid后，不管是管理磁盘、磁盘数据、oralce启动与中止、监听等都可由grid来操做；
使用grid用户netca建立监听
不在介绍
4、使用grid用户平常管理ORACLE

由于ASM管理的数据直接存储在磁盘上，平常备份通常采用RMAN备份，寒枫后续会介绍oracle11gR2数据库之RMAN备份。

近期忙于项目，博客已经近半年没有更新了，最近几个月由项目选型到方案设计，由招标文件起草到服务器选型，由服务器进场到系统部署，一步步妥而稳的进行，一每天忙而不乏的学习。终于项目定于11月5日上线，咱们执着，咱们坚信，咱们务实，咱们谨慎，预祝项目顺利上线。
寒枫最近太忙了，OCP在忙碌的过程当中已经首战告捷，接下来就是沉淀数据管理工做实际经验，固然保证数据的安全是每一个数据库管理员的第一个职责。

业余时间，寒枫仍然继续学习oracle这个神圣的机器，让咱们学习的思想像DBMS同样有条不絮的运转，将来的道路也渐行渐远。
