3.2 系统包

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@rac01yum.repos.d]# pwd

/etc/yum.repos.d

[root@rac01yum.repos.d]# vim yum.repo

[Oralin6u3]

name=local yum

baseurl=file:///mnt

gpgcheck=0

enabled=1

[root@rac01yum.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 rac01

192.168.31.200 rac02

##Public Virtual IP (VIP) addresses

192.168.31.10 rac01-vip

192.168.31.20 rac02-vip

##Private Interconnect

10.10.10.100 rac01-priv

10.10.10.200 rac02-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)

# PCI device 0x8086:0x1004 (e1000)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:63:ec:6e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x1004 (e1000)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:b5:91:c8", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"

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

[root@rac01 network-scripts]# vim ifcfg-eth0

DEVICE="eth0"

#BOOTPROTO="dhcp"

BOOTPROTO="static"

#HWADDR="08:00:27:CF:2B:A9"

HWADDR="08:00:27:63:ec:6e"

#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@dns01 ~]# yum install bind

[root@dns01 ~]# yum install bind-chroot

[root@dns01 ~]# 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

rac-scan IN A 192.168.31.50

[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

RAC01和RAC02配置DNS

---rac1:

[root@rac01~]# vim /etc/resolv.conf

# Generated by NetworkManager

##nameserver 8.8.8.8

domain cjc.com

nameserver 192.168.31.90

---rac2:

[root@rac02 ~]# nslookup 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RAC02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@rac01 ~]# ssh rac01cat .ssh/id_rsa.pub >> .ssh/authorized_keys

[oracle@rac01 ~]# sshrac01 cat .ssh/id_dsa.pub >> .ssh/authorized_keys

[oracle@rac01 ~]# ssh rac02 cat .ssh/id_rsa.pub >> .ssh/authorized_keys

[oracle@rac01 ~]# ssh rac02 cat .ssh/id_dsa.pub >> .ssh/authorized_keys

[oracle@rac01 ~]#scp .ssh/authorized_keys rac02:.ssh/authorized_keys

[oracle@rac01 ~]#chmod 700 .ssh

[oracle@rac01 ~]#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：

安装包：

[root@rac01 ~]# cd /package/

[root@rac01 package]# ll -rth

total 3.5G

[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
