chkconfig iptables off
service iptables stop
1、修改主机名
rac1&rac2
vi /etc/hosts
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
172.16.0.185 rac1
172.16.0.186 rac2
192.168.138.10 rac1priv
192.168.138.11 rac2priv
172.16.0.187 rac1vip
172.16.0.188 rac2vip
172.16.0.189 racscanip
cd /etc/yum.repos.d/
vi yum.repo
[server]
name=server
baseurl=file:///mnt/Server
qpqcheck=0
enabled=1
mount /dev/cdrom /mnt
yum repolist
2、安装软件包
rpm --import /etc/pki/rpm-gpg/RPM*
配置yum源
yum install -y binutils-* compat-libstdc++-33-* elfutils-libelf-* elfutils-libelf-devel-* gcc-* gcc-c++-* glibc-* glibc-common-* glibc-devel-* glibc-headers-* ksh-* libaio-* libgcc-* libstdc++-* make-* sysstat-* unixODBC-* unixODBC-devel-* compat-libcap*
比单机安装多安装 compat-libcap*
3、修改系统参数
vi /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
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
sysctl -p
vi /etc/security/limits.conf
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
4、增加组、用户、目录
groupadd -g 1000 oinstall
groupadd -g 1100 asmadmin
groupadd -g 1200 dba
groupadd -g 1300 asmdba
groupadd -g 1301 asmoper
useradd -u 1100 -g oinstall -G asmadmin,asmdba,asmoper -d /home/grid grid
useradd -u 1101 -g oinstall -G dba,asmdba -d /home/oracle oracle
echo grid | passwd --stdin grid
echo oracle | passwd --stdin oracle
mkdir -p /oracle/app/oraInventory
chown -R grid:oinstall /oracle/app/oraInventory
chmod -R 775 /oracle/app/oraInventory
mkdir -p /oracle/11.2.0/grid
mkdir -p /oracle/app/grid
chown -R grid:oinstall /oracle/app/grid
chown -R grid:oinstall /oracle/11.2.0/grid
chmod -R 775 /oracle/11.2.0/grid
mkdir -p /oracle/app/oracle
mkdir /oracle/app/oracle/cfgtoollogs
chown -R oracle:oinstall /oracle/app/oracle
chmod -R 775 /oracle/app/oracle
mkdir -p /oracle/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /oracle/app/oracle/product/11.2.0/db_1
chmod -R 775 /oracle/app/oracle/product/11.2.0/db_1
5、配置环境变量、互信
rac1
su - grid
vi .bash_profile
export ORACLE_SID=+ASM1
export ORACLE_BASE=/oracle/app/grid
export ORACLE_HOME=/oracle/11.2.0/grid
export PATH=$ORACLE_HOME/bin:$PATH
rac2
su - grid
vi .bash_profile
export ORACLE_SID=+ASM2
export ORACLE_BASE=/oracle/app/grid
export ORACLE_HOME=/oracle/11.2.0/grid
export PATH=$ORACLE_HOME/bin:$PATH
rac3
su - grid
vi .bash_profile
export ORACLE_SID=+ASM3
export ORACLE_BASE=/oracle/app/grid
export ORACLE_HOME=/oracle/11.2.0/grid
export PATH=$ORACLE_HOME/bin:$PATH
rac1
su - oracle
vi .bash_profile
export ORACLE_SID=+racdb1
export ORACLE_BASE=/oracle/app/oracle
export ORACLE_HOME=/oracle/app/oracle/product/11.2.0/db_1
export PATH=$ORACLE_HOME/bin:$PATH
rac2
su - oracle
vi .bash_profile
export ORACLE_SID=+racdb2
export ORACLE_BASE=/oracle/app/oracle
export ORACLE_HOME=/oracle/app/oracle/product/11.2.0/db_1
export PATH=$ORACLE_HOME/bin:$PATH
rac3
su - oracle
vi .bash_profile
export ORACLE_SID=+racdb3
export ORACLE_BASE=/oracle/app/oracle
export ORACLE_HOME=/oracle/app/oracle/product/11.2.0/db_1
export PATH=$ORACLE_HOME/bin:$PATH
2、创建共享磁盘
进入VMware Workstation软件安装目录，在命令提示符窗口敲入如下命令:
vmware-vdiskmanager -c -s 80Gb -a lsilogic -t 2 D:RacSharedDisk acsharedisk.vmdk
diskLib.dataCacheMaxSize=0
diskLib.dataCacheMaxReadAheadSize=0
diskLib.dataCacheMinReadAheadSize=0
diskLib.dataCachePageSize=4096
diskLib.maxUnsyncedWrites = "0"
disk.locking = "FALSE"
scsi1.sharedBus = "virtual"
scsi1.present = "TRUE"
scsi1.virtualDev = "lsilogic"
scsi1:0.mode = "independent-persistent"
scsi1:0.deviceType = "disk"
scsi1:0.present = "TRUE"
scsi1:0.fileName = "D:RacSharedDisk
acsharedisk.vmdk"
配置节点互信
/soft/grid/sshsetup/sshUserSetup.sh -user grid -hosts "rac1 rac2 rac3" -advanced -noPromptPassphrase
/soft/grid/sshsetup/sshUserSetup.sh -user oracle -hosts "rac1 rac2 rac3" -advanced -noPromptPassphrase
rac1&rac2
su - grid
ssh rac1 date
ssh rac2 date
ssh rac1priv date
ssh rac2priv date
su - oracle
ssh rac1 date
ssh rac2 date
ssh rac3 date
ssh rac1priv date
ssh rac2priv date
ssh rac3priv date
6、配置裸设备
vi /etc/udev/rules.d/60-raw.rules
ACTION=="add", KERNEL=="sdb1",RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sdb2",RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add",KERNEL=="raw*", OWNER="grid", GROUP="asmadmin", MODE="660"
partprobe
start_udev
raw -qa
ls -l /dev/raw
7、关闭各项服务
关闭服务
service iptables stop
chkconfig autofs off
chkconfig acpid off
chkconfig sendmail off
chkconfig cups-config-daemon off
chkconfig cpus off
chkconfig xfs off
chkconfig lm_sensors off
chkconfig gpm off
chkconfig openibd off
chkconfig pcmcia off
chkconfig cpuspeed off

chkconfig rpcidmapd off
chkconfig apmd off
chkconfig sendmail off
chkconfig arptables_jf off
chkconifg microcode_ctl off
chkconfig rpcgssd off
chkconfig ntpd off
8、开始安装
上传软件包并解压
cd /soft/grid/
./runInstaller

安装oracle11g r2 RAC时遭遇无法启动scan ip的错误（crs-5005）
1.环境信息：
数据库：11.2.0.4 RAC
OS：Centos 6.8
2.问题描述：
今天在虚拟机上安装一个11g的RAC 玩玩，节点1执行root是没有问题，在节点2上执行时就报了以下这个错误：

[root@rac2 app]#
于是在网上查找资料，很多人在安装的时候遇到过这种情形，但是却没查到是如何解决的，有的人干脆重新安装，
在网上和咨询别人无果的情况下，自己就试着重新执行一边root，居然这次执行成功了，以下是我的操作步骤：
a）首先在节点2上把 crs关掉
[root@rac2 ~]# /u01/app/grid/product/11.2.0/grid_1/bin/crsctl stop crs -f
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'rac2'

b）确定crs已经关掉之后，再次执行root脚本
root@rac2 app]# /u01/app/grid/product/11.2.0/grid_1/root.sh
Performing root user operation for Oracle 11g
The following environment variables are set as:
ORACLE_OWNER= grid
