创新互联自2013年起，先为莱山等服务建站，莱山等地企业，进行企业商务咨询服务。为莱山企业网站制作PC+手机+微官网三网同步一站式服务解决您的所有建站问题。

操作系统:oracle linux 5.8 64位

集群软件:linux.x64_11gR2_grid.zip

数据库:linux.x64_11gR2_database_1of1.zip,linux.x64_11gR2_database_1of2.zip

cpu:1颗

内存:必须1.5G以上(一般是2G)

本地磁盘:20G(根分区9G,swap是2G,home分区是9G)

asm软件: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

IP地址划分:192.168.3.100   rac1      eth0

       192.168.3.101   rac2      eth0

       192.168.3.200   rac1-vip   eth0:1

       192.168.3.201   rac2-vip   eth0:1

IP说明:

      每台服务器必须两块网卡, public ip,priv ip和scan ip必须在同一网段.public和priv必须在网卡中写明地址,vip在地址是自己添加的.

1.安装操作系统,图形化安装

    安装系统时将iptable和selinux全部禁用

2.配置虚拟机的网卡

rac1节点:

[root@rac1 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:0C:29:BE:51:CE
ONBOOT=yes
DHCP_HOSTNAME=rac1
IPADDR=192.168.3.100
NETMASK=255.255.255.0

[root@rac1 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth2

DEVICE=eth2
BOOTPROTO=static
HWADDR=00:0C:29:BE:51:D8
ONBOOT=yes
HOTPLUG=no
DHCP_HOSTNAME=rac1
IPADDR=10.0.0.1

[root@rac1 ~]# /etc/init.d/network restart
Shutting down interface eth0:        [  OK  ]
Shutting down interface eth2:        [  OK  ]
Shutting down loopback interface:     [  OK  ]
Bringing up loopback interface:       [  OK  ]
Bringing up interface eth0:           [  OK  ]
Bringing up interface eth2:         [  OK  ]
[root@rac1 ~]#

rac2节点:

[root@rac2 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:0C:29:7B:C0:13
ONBOOT=yes
DHCP_HOSTNAME=rac2
IPADDR=192.168.3.101
NETMASK=255.255.255.0

[root@rac2 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth2

DEVICE=eth2
BOOTPROTO=static
HWADDR=00:0C:29:7B:C0:1D
ONBOOT=yes
DHCP_HOSTNAME=rac2
IPADDR=10.0.0.2
[root@rac2 ~]#

3.配置hosts文件,主机名与IP地址解析(两个节点都是一样的)

[root@rac1 ~]# vim /etc/hosts
192.168.3.100   rac1.localdomain  rac1
192.168.3.101   rac2.localdomain  rac2
192.168.3.200   rac1-vip.localdomain  rac1-vip
192.168.3.201   rac2-vip.localdomain  rac2-vip
10.0.0.1       rac1-priv.localdomain  rac1-priv
10.0.0.2       rac2-priv.localdomain  rac2-priv
#192.168.3.155   scan-cluster.localdomain   scan-cluster   --注意,scan是用DNS解析的，在hosts文件中就不需要要定义了,否则会出错

[root@rac1 ~]#

4.光盘镜像挂载,安装软件依赖包(两个节点是一样的)

[root@rac1 ~]# mount /dev/cdrom /mnt/
mount: block device /dev/cdrom is write-protected, mounting read-only
[root@rac1 ~]# vim /etc/yum.repos.d/centos.repo
[centos]
name=centos
baseurl=file:///mnt/Server
gpgcheck=1
enabled=1
gpgkey=file:///mnt/RPM-GPG-KEY-oracle
[root@rac1 ~]# yum repolist

[root@rac1 ~]# yum -y install compat-libstdc++-33 elfutils-libelf-devel gcc  gcc-c++ glibc-devel glibc-headers libaio-devel  libstdc++-devel  sysstat  unixODBC unixODBC-devel bind bind-chroot bind-lib -y

5.配置DNS,解析rac1,rac2,scan-cluster的IP地址

[root@rac1 ~]# cd /var/named/chroot/etc/          

[root@rac1 etc]# cp -p named.caching-nameserver.conf  named.conf 

[root@rac1 etc]# vim named.conf 

listen-on port 53 { any; };

allow-query     { any; };

allow-query-cache { any; };

match-clients      { any; };

match-destinations { any; };

[root@rac1 etc]# vim named.rfc1912.zones    --添加域名反向解析

zone "3.168.192.in-addr.arpa" IN {

        type master;

        file "3.168.192.in-addr.arpa";

        allow-update { none; };

};

[root@rac1 etc]# cd /var/named/chroot/var/named/

[root@rac1 named]# cp -p localdomain.zone  3.168.192.in-addr.arpa 

[root@rac1 named]# vim 3.168.192.in-addr.arpa 

[root@rac1 named]# vim localdomain.zone

[root@rac1 named]# /etc/init.d/named restart

6.修改内核参数(两个节点必须一至)

[root@rac1 ~]# vim /etc/sysctl.conf

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmmax = 4294967295
kernel.shmall = 2097152
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
[root@rac1 ~]#sysctl -p        --使配置生效

7.创建用户，用户组,用户设置密码(两个节点必须一至)

[root@rac1 ~]# groupadd  -g 1000 oinstall
[root@rac1 ~]# groupadd  -g 1001 dba
[root@rac1 ~]# groupadd  -g 1002 oper
[root@rac1 ~]# groupadd  -g 1003 asmadmin
[root@rac1 ~]# groupadd  -g 1004 asmdba
[root@rac1 ~]# groupadd  -g 1005 asmoper
[root@rac2 ~]# useradd -u 1000 -g oinstall -G dba,oper,asmdba -d /home/oracle oracle

[root@rac1 ~]# passwd oracle
Changing password for user oracle.
New UNIX password:
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[root@rac2 ~]# useradd -u 1001 -g oinstall -G dba,asmadmin,asmoper,asmdba -d /home/grid grid
[root@rac1 ~]# passwd  grid
Changing password for user grid.
New UNIX password:
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[root@rac1 ~]#

8.创建oracle与grid存放的目录(两个节点必须一至)

[root@rac1 ~]# mkdir -p /home/grid/app

[root@rac1 ~]# mkdir -p /home/grid/11.2.0/grid  --ORACLE_HOME目录不能在ORACLE_BASE目录在下面,否则会报错
[root@rac1 ~]# chown -R grid:oinstall /home/grid/app
[root@rac1 ~]# mkdir /home/oracle/app -p
[root@rac1 ~]# mkdir /home/oracle/app/oracle/product/11.2.0/db_1 -p
[root@rac1 ~]# chown -R oracle:oinstall /home/oracle/
[root@rac1 ~]#

9.修改用户对文件打开的限制(两个节点一至)

[root@rac1 ~]# vim /etc/security/limits.conf
grid   soft   nofile  1024
grid   hard   nofile  65536
grid   soft   nproc   2047
grid   hard   nproc   16384
oracle  soft   nofile  1024
oracle  hard   nofile  65536
oracle  soft   nproc   2047
oracle  hard   nproc   16384
[root@rac1 ~]#

10.登陆oracle用户添加环境变量和ssh互相信任

[root@rac1 ~]# su - oracle
[oracle@rac1 ~]$ vim .bash_profile
export ORACLE_BASE=/home/oracle/app
export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/db_1

11.登陆grid用户添加环境变量,ssh互相信任

rac1节点:

[root@rac1 ~]# su - grid
[grid@rac1 ~]$ vim .bash_profile

12.修改用户登陆模块,停止ntpd服务(两个节点一样)

[root@rac1 ~]# vim /etc/pam.d/login
session   required     /lib64/security/pam_limits.so
session   required     pam_limits.so
[root@rac1 ~]# mv  /etc/ntp.conf  /etc/ntp.conf.back
[root@rac1 ~]# /etc/init.d/ntpd stop
Shutting down ntpd:                  [FAILED]
[root@rac1 ~]#

13.关闭rac1节点,添加本地磁盘,使用iscsi共享存储

ocr盘:1G           /dev/sdb

voting disk盘:1G     /dev/sdc

FLASK recovery盘:10G  /dev/sdd

DATA disk盘:10G      /dev/sde

rac1节点:(添加磁盘的节点)

(1).在rac1节点添加磁盘

(2).在rac1和rac2的配置文件添加参数

disk.locking="FALSE"

scsi1.SharedBus="Virtual"

scsi1.shared="TRUE"

(3).在rac2添加已有的磁盘,在rac1创建的磁盘

14.安装oracleasm软件包,创建自动存储(两个节点必须全部安装)

[root@rac1 ~]# yum install oracleasm*
[root@rac1 ~]# rpm -ivh oracleasmlib-2.0.4-1.el5.x86_64.rpm
[root@rac1 ~]# /etc/init.d/oracleasm configure -i
Configuring the Oracle ASM library driver.

This will configure the on-boot properties of the Oracle ASM library
driver.  The following questions will determine whether the driver is
loaded on boot and what permissions it will have.  The current values
will be shown in brackets ('[]').  Hitting without typing an
answer will keep that current value.  Ctrl-C will abort.

Default user to own the driver interface []: grid

15.grid集群软件安装(安装之前检查下条件)

[grid@rac1 grid]# ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose

####检查结果必须是:Pre-check for cluster services  setup was successful .否则安装不成功

下面图有点问题:Cluster Name:应该是scan-cluster,SCAN Name:应该是scan-cluster.localdomain

脚本执行顺序:

先在rac1节点执行orainstRoot.sh脚本

然后在rac2节点执行orainstRoot.sh脚本

最后在rac1节点执行root.sh脚本

最后在rac2节点执行root.sh脚本

完成
