配置 YUM
[root@ rac01 ~]# mount |grep OL
/dev/sr1 on /media/OL6.3 x86_64 Disc 1 20120626 type iso9660 (ro,nosuid,nodev,uhelper=udisks,uid=0,gid=0,iocharset=utf8,mode=0400,dmode=0500)
[root@ rac01 ~]# mount /dev/sr1 /mnt -o loop
[root@ rac01 yum.repos.d]# pwd
/etc/yum.repos.d
[root@ rac01 yum.repos.d]# vim yum.repo
[Oralin6u3]
name=local yum
baseurl=file:///mnt
gpgcheck=0

[root@ rac01 yum.repos.d]# yum -y install binutils-2.20.51.0.2-5.11.el6 compat-libcap1-1.10-1 compat-libstdc++-33-3.2.3-69.el6 compat-libstdc++-33-3.2.3-69.el6.i686 gcc-4.4.4-13.el6 gcc-c++-4.4.4-13.el6 glibc-2.12-1.7.el6 glibc-2.12-1.7.el6 glibc-devel-2.12-1.7.el6 glibc-devel-2.12-1.7.el6.i686 ksh libgcc-4.4.4-13.el6 libgcc-4.4.4-13.el6 libstdc++-4.4.4-13.el6 libstdc++-4.4.4-13.el6.i686 libstdc++-devel-4.4.4-13.el6 libstdc++-devel-4.4.4-13.el6.i686 libaio-0.3.107-10.el6 libaio-0.3.107-10.el6.i686 libaio-devel-0.3.107-10.el6 libaio-devel-0.3.107-10.el6.i686 make-3.81-19.el6 sysstat-9.0.4-11.el6
3.3 hosts 配置
[root@ rac01 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
##Public Network
192.168.31.100 rac 0 1
192.168.31.200 rac 0 2
##Public Virtual IP (VIP) addresses
192.168.31.10 rac 0 1-vip
192.168.31.20 rac 0 2-vip
##Private Interconnect
10.10.10.100 rac 0 1-priv
10.10.10.200 rac 0 2-priv
##Scan ip
##192.168.31.50 rac-scan.cjc.com
3.4 创建用户组
/usr/sbin/groupadd -g 5000 dba
/usr/sbin/groupadd -g 5001 oinstall
/usr/sbin/groupadd -g 5002 oper
/usr/sbin/groupadd -g 5003 asmadmin
/usr/sbin/groupadd -g 5004 asmoper
/usr/sbin/groupadd -g 5005 asmdba
/usr/sbin/useradd -g oinstall -G asmadmin,asmdba,asmoper,dba grid
/usr/sbin/useradd -g oinstall -G dba,asmdba oracle
12C开始，还需要配置下面的用户组
/usr/sbin/groupadd -g 5006 backupdba
/usr/sbin/groupadd -g 5007 dgdba
/usr/sbin/groupadd -g 5008 kmdba
/usr/sbin/groupadd -g 5009 racdba
3.5 创建目录并授权
[root@ rac01 ~]# mkdir -p /u01/app/11.2.0/grid
[root@ rac01 ~]# mkdir -p /u01/app/grid
[root@ rac01 ~]# mkdir -p /u01/app/oracle/product/11.2.0/db_1
[root@ rac01 ~]# chown -R grid:oinstall /u01
[root@ rac01 ~]# chmod -R 775 /u01/
[root@ rac01 ~]# chown -R oracle:oinstall /u01/app/oracle
3.6 设置环境变量 grid 和 oracle 用户环境变量
[grid@ rac01 ~]$ vim .bash_profile
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/11.2.0/grid
export ORACLE_SID=+ASM1
PATH=$PATH:$ORACLE_HOME/bin
[grid@ rac01 ~]$ source .bash_profile
[oracle@ rac01 ~]$ vi .bash_profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
export ORACLE_SID=cjcdb01
PATH=$PATH:$ORACLE_HOME/bin
[oracle@ rac01 ~]$ source .bash_profile
3.7 关闭 SELINUX
[root@ rac01 ~]# vim /etc/selinux/config
#SELINUX=enforcing
SELINUX=disabled
3.8 关闭防火墙
Linux 6
[root@ rac01 ~]# service iptables stop
[root@ rac01 ~]# chkconfig iptables off
Linux 7
[root@ rac01 ~]# systemctl stop firewalld.service
[root@ rac01 ~]# systemctl disable firewalld.service
[root@ rac01 ~]# iptables -F
[root@ rac01 ~]# iptables-save
3.9 设置 Oracle 和 Grid 用户的 SHELL 限制
[root@ rac01 ~]# vi /etc/security/limits.conf
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 131072
grid hard nofile 65536
grid soft stack 10240
grid hard stack 32768
oracle soft nproc 131072
oracle hard nproc 131072
oracle soft nofile 131072
oracle hard nofile 65536
oracle hard nofile 131072
oracle soft nofile 131072
3.10 修改内核参数
[root@ rac01 ~]# vim /etc/sysctl.conf
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
kernel.shmmax = 4398046511104
kernel.shmall = 1073741824
fs.file-max = 6815744
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576
[root@ rac01 ~]# sysctl -p
四： RAC01 服务器完整克隆
克隆RAC02 数据库服务器和 DNS01 服务器
克隆后修改网络和主机名
[root@rac01 rules.d]# pwd
/etc/udev/rules.d
[root@rac01 rules.d]# vim 70-persistent-net.rules
# PCI device 0x8086:0x1004 (e1000)

[root@rac01 rules.d]# cd /etc/sysconfig/network-scripts/
[root@rac01 network-scripts]# vim ifcfg-eth0

#PREFIX="24"
#GETWAY=10.10.10.1
#DNS1="8.8.8.8"
[root@rac01 ~]# service network restart
更改主机名
[root@rac01 ~]# vim /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=rac02
五：配置DNS
DNS01:
1. 安装 dns, 这里直接利用 yum 安装：
[root@ dns 01 ~]# yum install bind
[root@ dns 01 ~]# yum install bind-chroot
[root@ dns 01 ~]# yum install caching-nameserver
[root@dns01 ~]# cp /etc/named.conf /root
[root@dns01 ~]# vim /etc/named.conf
options {
listen-on port 53 { any; };
listen-on-v6 port 53 { any; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
allow-query { any; };
recursion yes;
......
[root@dns01 ~]# cp /etc/named.rfc1912.zones /package/
[root@dns01 ~]# vim /etc/named.rfc1912.zones
// 配置正向解析 Zone
zone "cjc.com" IN {
type master;
file "cjc.com.zone";
allow-update { none; };
};
// 配置反向解析 Zone
zone "31.168.192.in-addr.arpa" IN {
type master;
file "chen.com.zone";
allow-update { none; };
};
[root@dns01 ~]# vim /var/named/cjc.com.zone
$TTL 86400
@ IN SOA oracle.cjc.com. root.cjc.com. (
42 ; serial (d.adams)
3H ; refresh
15M ; retry
1W ; expiry
1D) ; minimum
IN NS dns.cjc.com.
dns IN A 192.168.31.90
rac1 IN A 192.168.31.100
rac2 IN A 192.168.31.200

[root@dns01 ~]# vim /var/named/chen.com.zone

[root@dns01 ~]# chkconfig named on
[root@dns01 ~]# service named restart
[root@dns01 ~]# named-checkconf -z /etc/named.conf
zone localhost.localdomain/IN: loaded serial 0
zone localhost/IN: loaded serial 0
zone 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa/IN: loaded serial 0

zone cjc.com/IN: loaded serial 42
zone 31.168.192.in-addr.arpa/IN: loaded serial 1997022700
RAC01 和 RAC0 2 配置 DNS
---rac1:
[root@rac0 1 ~]# vim /etc/resolv.conf
# Generated by NetworkManager
##nameserver 8.8.8.8
domain cjc.com
nameserver 192.168.31.90
options rotate
options timeout:2
options attempts:5
---rac2:
[root@rac02 ~]# vim /etc/resolv.conf
# Generated by NetworkManager
##nameserver 8.8.8.8
domain cjc.com
nameserver 192.168.31.90
options rotate
options timeout:2
options attempts:5
[root@rac02 ~]# nslookup rac-scan.cjc.com
Server: 192.168.31.90
Address: 192.168.31.90#53
Name: rac-scan.cjc.com
Address: 192.168.31.60
Name: rac-scan.cjc.com
Address: 192.168.31.70
Name: rac-scan.cjc.com
Address: 192.168.31.50
六： RAC01 和 RAC0 2 配置
6.1 SSH 互信
SSH 互信
两节点都做 (oracle 和 grid 用户 都执行)
[oracle@ rac01 ~]$ mkdir .ssh/
[oracle@ rac01 ~]$ ssh-keygen -t rsa
[oracle@ rac01 ~]$ ssh-keygen -t dsa
[oracle@ rac02 ~]$ mkdir .ssh/
[oracle@ rac02 ~]$ ssh-keygen -t rsa
[oracle@ rac02 ~]$ ssh-keygen -t dsa
[oracle@ rac0 1 ~]# ssh rac01 cat .ssh/id_rsa.pub >> .ssh/authorized_keys
[oracle@ rac0 1 ~]# ssh rac0 1 cat .ssh/id_dsa.pub >> .ssh/authorized_keys
[oracle@ rac0 1 ~]# ssh rac0 2 cat .ssh/id_rsa.pub >> .ssh/authorized_keys
[oracle@ rac0 1 ~]# ssh rac0 2 cat .ssh/id_dsa.pub >> .ssh/authorized_keys
[oracle@ rac0 1 ~]# scp .ssh/authorized_keys rac 0 2:.ssh/authorized_keys
[oracle@ rac0 1 ~]# chmod 700 .ssh
[oracle@ rac0 1 ~]# chmod 600 .ssh/authorized_keys
[oracle@ rac02 ~]# chmod 700 .ssh
[oracle@ rac02 ~]# chmod 600 .ssh/authorized_keys
验证：grid和oracle用户下分别验证ssh 本机和 另一台服务器不需要输入密码；
七 共享存储设置
共享存储：

八： 安装GI 前检查
安装包：
[root@rac01 ~]# cd /package/
[root@rac01 package]# ll -rth
total 3.5G
-rw-r--r-- 1 root root 1.1G May 1 23:05 p13390677_112040_Linux-x86-64_2of7.zip

-rw-r--r-- 1 root root 1.2G May 1 23:06 p13390677_112040_Linux-x86-64_3of7.zip
[root@rac01 package]# unzip p13390677_112040_Linux-x86-64_3of7.zip
12c 版本开始安装包需要解压到 grid_home/oracle_home 目录下
[root@rac01 package]# chown grid.oinstall grid/ -R
[root@rac01 package]# xhost +
[grid@rac01 grid]$ vim /home/grid/pre.log
