oracle rac 11.0.2.4初学者简要安装步骤

1.VMware环境：两台安装linux的虚拟机，本次我使用的red hat 6.8，每台两个网卡public/private。

搞几个共享磁盘出来

cmd切换到VMware安装目录下，执行创建共享磁盘.

vmware-vdiskmanager.exe -c -s 1G -a lsilogic -t 2 C:\share_disk\ocr01.vmdk

vmware-vdiskmanager.exe -c -s 1G -a lsilogic -t 2 C:\share_disk\ocr02.vmdk

vmware-vdiskmanager.exe -c -s 1G -a lsilogic -t 2 C:\share_disk\ocr03.vmdk

vmware-vdiskmanager.exe -c -s 5G -a lsilogic -t 2 C:\share_disk\data.vmdk

vmware-vdiskmanager.exe -c -s 5G -a lsilogic -t 2 C:\share_disk\backup.vmdk

改虚拟机的.vmx文件，文件末尾添加刚才创建的虚拟磁盘.

scsi1.present = "TRUE"

scsi1.virtualDev = "lsilogic"

scsi1.sharedBus = "virtual"

scsi1:1.present = "TRUE"

scsi1:1.mode = "independent-persistent"

scsi1:1.filename = "C:\share_disk\ocr01.vmdk"

scsi1:1.deviceType = "disk"

scsi1:2.present = "TRUE"

scsi1:2.mode = "independent-persistent"

scsi1:2.filename = "C:\share_disk\ocr02.vmdk"

scsi1:2.deviceType = "disk"

scsi1:3.present = "TRUE"

scsi1:3.mode = "independent-persistent"

scsi1:3.filename = "C:\share_disk\ocr03.vmdk"

scsi1:3.deviceType = "disk"

scsi1:4.present = "TRUE"

scsi1:4.mode = "independent-persistent"

scsi1:4.filename = "C:\share_disk\backup.vmdk"

scsi1:4.deviceType = "disk"

scsi1:5.present = "TRUE"

scsi1:5.mode = "independent-persistent"

scsi1:5.filename = "C:\share_disk\data.vmdk"

scsi1:5.deviceType = "disk"

disk.locking = "false"

disk.EnableUUID = "true"

diskLib.dataCacheMaxSize = "0"

diskLib.dataCacheMaxReadAheadSize = "0"

diskLib.DataCacheMinReadAheadSize = "0"

diskLib.dataCachePageSize = "4096"

diskLib.maxUnsyncedWrites = "0"

2.开机检查两台主机都可以看到刚添加的共享盘，检查swap空间。

内存	Swap
1 - 2 GB	内存的1.5倍
2-16GB	和内存相等
>16GB	16 GB

3.操作系统配置

3.1关闭selinux

sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

3.2关闭iptables

rhel6

service iptables stop

chkconfig ip6tables off

chkconfig iptables off

rhel7

systemctl stop firewalld.service

systemctl disable firewalld.service

firewall-cmd --state

3.3改IP地址，改hosts文件

cat >> /etc/hosts <

2.2.2.10 rac1

2.2.2.11 rac1-vip

2.2.2.20 rac2

2.2.2.21 rac2-vip

2.2.2.15 rac-scan

192.168.88.200 rac1-priv

192.168.88.201 rac2-priv

EOF

禁用ntp，oracle rac中会使用ctss来同步集群时间.

mv /etc/ntp.conf /etc/ntp.conf.bak

3.4内核参数

cat >> /etc/sysctl.conf <

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 6815744

fs.aio-max-nr = 1048576

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 = 1048576

EOF

sysctl -p

3.5Limits

cat >> /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

EOF

12C：

grid soft stack 10240

oracle soft stack 10240

3.6 pam

echo session required pam_limits.so >>/etc/pam.d/login

3.7 profile

cat >>/etc/profile <

if [ $USER = "oracle" ] || [ $USER = "grid" ]; then

if [ $SHELL = "/bin/ksh" ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

umask 022

3.8 新建用户及更改环境变量.

export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1

export ORACLE_SID=jicheng1 ##rac2为jicheng2

export NLS_LANG=american_america.zhs16gbk

export PATH=.:$PATH:$ORACLE_HOME/bin:/ u01/11.2.0/grid/bin

export ORACLE_SID=+ASM1 ##rac2为ASM2

export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin:.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib

3.9 操作系统配置结束，reboot两台机器（改配置文件关selinux重启生效）

4.ASM盘，可以使用ASMlib和udev方式来绑定，本次使用udev来绑定ASM磁盘

取共享磁盘ssid，创建文件/etc/udev/rules.d/99-oracle.rules并写入，往rac2节点拷贝一份，同样启动start_udev

rhel6

for i in sdb sdc sdd sde sdf; do UUID=`/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$i` ; echo 'KERNEL=="sd*", BUS=="scsi", PROGRAM=="scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="'$UUID'", NAME="asm-'$i'", OWNER="grid", GROUP="asmadmin", MODE="0660"'; done >> /etc/udev/rules.d/99-oracle.rules ; cat /etc/udev/rules.d/99-oracle.rules

start_udev

ll /dev/asm*

scp/etc/udev/rules.d/99-oracle.rules 2.2.2.20:/etc/udev/rules.d/99-oracle.rules

rac2 :

start_udev

ll /dev/asm*

rhel7

for i in b c d e f

UUID=`/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`

echo 'KERNEL=="sd?",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="'$UUID'", SYMLINK+="asm-disk'$i'",OWNER="grid", GROUP="asmadmin",MODE="0660"'

done >> /etc/udev/rules.d/99-oracle.rules

/sbin/udevadm trigger --type=devices --action=change

udevadm control --reload-rules

5.上传文件，安装依赖包，图形界面安装grid，oracle数据库软件，DBCA建库。

5.1安装依赖包，配好yum装吧

yum install -y binutils compat-libstdc++-33 glibc ksh libaio libgcc libstdc++ make compat-libcap1 gcc gcc-c++ glibc-devel libaio-devel libstdc++-devel sysstat elfutils-libelf-devel

5.2图形界面grid用户运行 ./runInstaller

installation type 选高级.

oracle rac 11.0.2.4初学者简要安装步骤

添加rac2，配置双节点grid用户互信

oracle rac 11.0.2.4初学者简要安装步骤

注意选择路径，把刚才三个ocr磁盘选上

oracle rac 11.0.2.4初学者简要安装步骤

最后安装检查会报asm磁盘警告，检查两个节点都可以访问asm磁盘后直接忽略下一步.

dd if=/dev/zero f=/dev/asm-sda bs=1024 count=1

5.3安装完成运行root脚本，先在第一个节点上执行，然后其他节点顺序执行，不能同时执行

/u01/app/oraInventory/orainstRoot.sh

/u01/11.2.0/grid/root.sh

5.4验证集群

[root@rac1]# /oracle/11.2.0/grid/bin/crs_stat -t

5.5图形界面oracle用户运行 ./runInstaller

只安装数据库软件

oracle rac 11.0.2.4初学者简要安装步骤

添加rac2，设置oracle用户互信

oracle rac 11.0.2.4初学者简要安装步骤

5.6一路下一步到安装完成，同样执行root脚本

5.7DBCA建库，图形界面Oracle用户执行dbca

选rac数据库

oracle rac 11.0.2.4初学者简要安装步骤

自定义，定制

oracle rac 11.0.2.4初学者简要安装步骤

选中两个节点

oracle rac 11.0.2.4初学者简要安装步骤

使用ASM盘存储数据

oracle rac 11.0.2.4初学者简要安装步骤

后面配置就看需求了，测试环境可以都试一试.

结束。
