SELINUX=disabled 

 (3)修改主机名
编辑/etc/sysconfig/network
设置

HOSTNAME=db10a 

(4)修改/etc/hosts文件
添加

##Public Network - (eth0)192.168.1.10  db10a192.168.1.11  db10b##Private Interconnect - (eth1)192.168.2.10  db10a-priv192.168.2.11  db10b-priv##Public Virtual IP (VIP) addresses - (eth0)192.168.1.100  db10a-vip192.168.1.101  db10b-vip 

(5)创建所需用户和用户组

groupadd -g 500 oinstallgroupadd -g 501 dbauseradd -m -u 500 -g oinstall -G dba -d /home/oracle -s /bin/bash -c "Oracle Software Owner" oracle

设置密码：
passwd oracle
(6)创建所需目录并授权(其中media为存放oracle所需软件的目录)

mkdir -p /oracle/mediachown -R oracle:oinstall /oracle/media/chmod -R 775 /oracle/media/mkdir -p /u01/crs1020chown -R oracle:oinstall /u01/crs1020chmod -R 775 /u01/crs1020/mkdir -p /u01/app/oraclechown -R oracle:oinstall /u01/app/oracle/chmod -R 775 /u01/app/oracle/ 

(7)修改环境变量文件
su - oracle
vi .bash_profile
把文件中的内容替换

# .bash_profile# Get the aliases and functionsif [  -f ~/.bashrc ]; then. ~/.bashrcfi# User specific environment  and startup programsPATH=$PATH:$HOME/binexport PATH################################################### User specific environment  and startup programs##################################################export ORACLE_BASE=/u01/app/oracleexport ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1export CRS_HOME=/u01/crs1020export ORA_CRS_HOME=/u01/crs1020export ORACLE_PATH=$ORACLE_BASE/common/oracle/sql:.:$ORACLE_HOME/rdbms/admin################################################### Each RAC node must have a unique ORACLE_SID.

(8)修改内核参数
vi /etc/sysctl.conf
添加：

kernel.shmmax = 4294967295kernel.shmmni = 4096kernel.sem = 250 32000 100 128fs.file-max = 65536net.ipv4.ip_local_port_range  = 1024 65000net.core.rmem_default  = 1048576net.core.rmem_max  = 1048576net.core.wmem_default  = 262144net.core.wmem_max  = 262144

生效
sysctl -p 

(9)限制参数
编辑/etc/security/limits.conf
添加：

oracle soft nproc   2047oracle hard nproc  16384oracle soft nofile 1024oracle hard nofile 65536 

在/etc/pam.d/login中添加：
session required /lib/security/pam_limits.so
如下：
cat >> /etc/pam.d/login  << EOF
session required /lib/security/pam_limits.so
EOF 

(10)设置计时器
cat >> /etc/rc.local << EOF
modprobe  hangcheck-timer hangcheck-tick=30 hangcheck_margin=180
EOF 

(11)检查安装包并安装所需要的rpm包

rpm -q --qf ‘%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n‘ binutils compat-libstdc++-33 elfutils-libelf  elfutils-libelf-devel elfutils-libelf-devel-static gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers kernel-headers ksh libaio libaio-devel libgcc libgomp libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel libXp 

可配置本地yum源
a.mount /dev/cdrom /mnt
b.cat >> /etc/yum.repos.d/dvd.repo<<EOF
[dvd]
name=install dvd
baseurl=file:///mnt/Server 
enabled=1
gpgcheck=0
EOF
c.yum clean all
d.yum list 

配置成功后，安装缺失软件包 

(12)配置并启动ntp服务
ntp服务
rpm  -qa | grep ntp
vi /etc/ntp.conf
restrict 192.168.1.0 mask 255.255.255.0 nomodify  notrap 

service ntpd  start 

chkconfig ntpd on 

(13)关闭虚拟机，添加共享磁盘(这一步最好在前面开始的时候做，否则多重启一下虚拟机系统) 

添加4块儿磁盘：ocr磁盘为100M 
                             voting disk 为:100M
                             ASM1:2G
                             ASM2:2G
添加的4块儿磁盘要与本地的磁盘不要设置在同一总线下 

在节点以的vmx文件中添加(开启前添加)：
disk.locking="false"  
diskLib.dataCacheMaxSize = "0" 
diskLib.dataCacheMaxReadAheadSize = "0"  
diskLib.DataCacheMinReadAheadSize = "0"  
diskLib.dataCachePageSize = "4096" 
diskLib.maxUnsyncedWrites = "0"  
scsi1:0.deviceType = "disk" 
scsi1:1.deviceType = "disk" 
scsi1:2.deviceType = "disk" 
scsi1:3.deviceType = "disk"
disk.EnableUUID ="true" 

对4块儿盘进行分区
fdisk /dev/sdb
分别为：sdb1,sdc1,sdd1,sde1 

使用udev进行绑定裸设备
编辑/etc/udev/rules.d/60-raw.rules 
添加：
ACTION=="add", KERNEL=="sdb", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sdc", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sdd", RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", KERNEL=="sde", RUN+="/bin/raw /dev/raw/raw4 %N"
KERNEL=="raw[1-4]", OWNER="oracle", GROUP="oinstall", MODE="660"
重启udev
start_udev
查看：
[root@db10a ~]# raw -qa
/dev/raw/raw1:  bound to major 8, minor 16
/dev/raw/raw2:  bound to major 8, minor 32
/dev/raw/raw3:  bound to major 8, minor 48
/dev/raw/raw4:  bound to major 8, minor 64
[root@db10a ~]# ls -l /dev/raw
total 0
crw-rw---- 1 oracle oinstall 162, 1 Sep  9 09:46 raw1
crw-rw---- 1 oracle oinstall 162, 2 Sep  9 09:46 raw2
crw-rw---- 1 oracle oinstall 162, 3 Sep  9 09:46 raw3
crw-rw---- 1 oracle oinstall 162, 4 Sep  9 09:46 raw4
注意权限和属组 

使用上面的方式进行绑定的时候报磁盘没有共享的错误
使用rawdevice方式进行绑定
在/etc/sysconfig/rawdevices 中加入：
/dev/raw/raw1   /dev/sdb1
/dev/raw/raw2   /dev/sdc1
/dev/raw/raw3   /dev/sdd1
/dev/raw/raw4   /dev/sde1
将赋权限的命令加到/etc/rc.d/rc.local文件中，以便重启的时候对裸设备赋正确的权限
chown –R  oracle:oinstall /dev/raw/raw*
chmod 660 /dev/raw/raw* 

副节点设置
(1)复制或者克隆节点一
(2)修改的地方有
IP地址
主机名
oracle用户中的实例名(这里是testdb102)

3.配互信
在主节点
节点一

一去一回，完全不用进行手动操作，两个节点间的互信关系就此配置完毕！！！ 

PS：保证两节点的时间同步，在二节点停止ntpd服务，并部署下面的脚本，1s进行一次时间同步
[root@rac2 ~]# cat ntpdate_to_rac1.sh -----注意：使用这个脚本的时候客户端的ntpd服务不启动
while :; do ntpdate db10a; sleep 1; done 
如若仍不满足需求，可以在后台同时启动多个同步脚本。后台启动方法如下。 
[root@rac2 ~]# nohup sh ntpdate_to_rac1.sh >> ntpdate_to_rac1.log&
[root@db10b ~]# tail -f ntpdate_to_rac1.log 
9 Sep 22:51:20 ntpdate[9892]: adjust time server 192.168.1.10 offset -0.000113 sec

9 Sep 22:51:26 ntpdate[9904]: adjust time server 192.168.1.10 offset -0.000017 sec
.....
4.一切就绪，安装cluster软件
解压：
gzip -d 10201_clusterware_linux_x86_64.cpio.gz
gzip -d 10201_database_linux_x86_64.cpio.gz
cpio -idmv < 10201_clusterware_linux_x86_64.cpio
cpio -idmv < 10201_database_linux_x86_64.cpio 

检查安装环境：
cd /oracle/media/clusterware/
./runcluvfy.sh  stage -pre crsinst -n db10a,db10b -verbose
检查报：
Could not find a suitable set of interfaces for VIPs.
忽略，继续安装 

安装cluster软件的最后要执行两个脚本
[root@rac1 ~]# /u01/app/oracle/oraInventory/orainstRoot.sh  

Changing permissions of /u01/app/oracle/oraInventory to 770.
Changing groupname of /u01/app/oracle/oraInventory to oinstall.
The execution of the script is complete 

[root@rac2 ~]# /u01/app/oracle/oraInventory/orainstRoot.sh 

Changing permissions of /u01/app/oracle/oraInventory to 770.
Changing groupname of /u01/app/oracle/oraInventory to oinstall. 
The execution of the script is complete 

第二个脚本在第一个节点 rac1 上执行
[root@rac1 ~]# /u01/crs1020/root.sh      -----时间较长
在第二个节点 rac2 上执行这个脚本前，完成以下工作
[root@rac2 ~]# cd /u01/crs1020/bin/
[root@rac2 bin]# vi vipca
在
if [ "$arch" = "i686" -o "$arch" = "ia64" ]        then
            LD_ASSUME_KERNEL=2.4.19             
            export LD_ASSUME_KERNEL
       fi
下面加入
unset LD_ASSUME_KERNEL
[root@rac2 bin]# vi srvctl
在
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
下面加入
unset LD_ASSUME_KERNEL
此时
Rac2 上执行
[root@rac2 ~]# /u01/crs1020/root.sh
最后还会报错
Running vipca(silent) for configuring nodeapps
Error 0(Native: listNetInterfaces:[3])   [Error 0(Native: listNetInterfaces:[3])]
解决办法：
[root@rac2 bin]# ./oifcfg getif 

[root@rac2 bin]# ./oifcfg iflist 

eth0  192.168.1.0 

eth1  192.168.2.0 

eth2  192.168.0.0
[root@rac2 bin]# ./oifcfg setif -global eth0/192.168.1.0:public
[root@rac2 bin]# ./oifcfg setif -global eth1/192.168.2.0:cluster_interconnect
[root@rac2 bin]# ./oifcfg getif 

eth0  192.168.1.0  global  public 

eth1  192.168.2.0  global  cluster_interconnect


然后 rac2 上启动 vipca 图形界面
[root@rac2 ~]# cd /u01/crs1020/bin/
[root@rac2 bin]# ./vipca 

点击 next 



5.安装数据库软件
在安装的时候选择只安装软件 

6.listener配置
手工配置或者使用netca配置（推荐使用netca）
安装完成之后使用crs_stat命令查看：
[root@db10b ~]# /u01/crs1020/bin/crs_stat -t -v
Name           Type           R/RA   F/FT   Target    State     Host        
----------------------------------------------------------------------

ora.db10b.vip  application    0/0    0/0    ONLINE    ONLINE    db10b 

7.创建ASM实例和创建数据库 

最后一步，使用dbca建库
testdb101@db10a  /home/oracle$ crs_stat -t -v
Name           Type           R/RA   F/FT   Target    State     Host        
----------------------------------------------------------------------

问题总结

这次安装RAC是遇到问题最多的一次，一一总结如下吧。

第一，

在节点二执行root.sh的时候报下面的错
[root@db10b bin]#  /u01/crs1020/root.sh
Checking to see if Oracle CRS stack is already configured 

Setting the permissions on OCR backup directory
