系统都已经安装好了，IP和主机名都设置好了。
1.配置OEL1的NTP服务：
a.[root@oel1 ~]# cat >>/etc/ntp.conf <<EOF
> restrict 0.0.0.0 mask 0.0.0.0 nomodify
> server 127.127.1.0
> fudge 127.127.1.0 stratum 10
> driftfile /var/lib/ntp/drift
> broadcastdelay 0.008
> authenticate no
> keys /etc/ntp/keys
> EOF
[root@oel1 ~]# service ntpd start #启动NTP服务
Starting ntpd: [ OK ]
[root@oel1 ~]# chkconfig ntpd on #
[root@oel1 ~]# chkconfig --list ntpd
ntpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
b.配置OEL2的NTP服务：
[root@oel2 ~]# cat >>/etc/ntp.conf<<EOF
> server 128.192.0.1
> fudge 127.127.1.0 stratum 10
> driftfile /var/lib/ntp/drift
> broadcastdelay 0.008
> authenticate no
> keys /etc/ntp/keys
> EOF
[root@oel2 ~]# service ntpd stop
[root@oel2 ~]# ntpdate 128.192.0.1
23 Nov 16:23:28 ntpdate[5258]: step time server 128.192.0.1 offset -3.940062 sec
[root@oel2 ~]# service ntpd start
Starting ntpd: [ OK ]
2.配置HOSTS（OEL1,OEL2)
[root@oel1 ~]# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 oel1 localhost.localdomain localhost
128.192.0.1 oel1
128.192.0.2 oel2
128.192.0.3 oel1-vip
128.192.0.4 oel2-vip
10.10.10.1 oel1-priv
10.10.10.2 oel2-priv
3.分区：（已经分好了）
[root@oel1 ~]# fdisk -l
4.在OEL1 和OEL2 上使用root 用户执行以下命令
cat >> /etc/profile << EOF
export PATH=$PATH:/u01/app/oracle/product/10.2/crs/bin
EOF
5。配置hang-checker 模块
在 OEL1 和OEL2 主机上，使用root 用户执行
cat >>/etc/modprobe.conf <<EOF
options hangcheck�\timer hangcheck_tick=30 hangcheck_margin=180
EOF
cat >>/etc/rc.local <<EOF
modprobe �\v hangcheck�\timer
EOF
6.在OEL1和OEL2上配置内核参数
[root@oel1 ~]# vi /etc/sysctl.conf
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144
7.在OEL1和OEL2上配置oracle用户权限
[root@oel1 ~]# vi /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
vi /etc/pam.d/login
session required /lib/security/pam_limits.so
8.在OEL1和OEL2上创建oracle账户信息：
[root@oel1 ~]# groupadd -g 500 oinstall
[root@oel1 ~]# groupadd -g 501 dba
[root@oel1 ~]# groupadd -g 502 oper
[root@oel1 ~]# useradd -m -g oinstall -G dba,oper -u 500 oracle
修改ORacle用户密码:
[root@oel2 ~]# passwd oracle
Changing password for user oracle.
New UNIX password:
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
9.在OEl1和OEL2上配置ORacle用户环境变量
[root@oel1 ~]# su - oracle
[oracle@oel1 ~]$ vi .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
unset USERNAME
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2/db
export CRS_HOME=$ORACLE_BASE/product/10.2/crs
export ORACLE_SID=prod1
export PATH=$PATH:$ORACLE_HOME/bin:$CRS_HOME/bin
10.在OEL1和OEL2上为ORacle配置SSH
[oracle@oel1 ~]$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_rsa):
Created directory '/home/oracle/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_rsa.
Your public key has been saved in /home/oracle/.ssh/id_rsa.pub.
The key fingerprint is:
c9:4f:d0:88:4e:23:61:f1:70:21:bb:b0:df:ed:72:4a oracle@oel1
[oracle@oel1 ~]$ ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_dsa): Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_dsa.
Your public key has been saved in /home/oracle/.ssh/id_dsa.pub.
The key fingerprint is:
a7:6e:31:02:e5:eb:a4:9a:f7:4c:9a:72:98:25:26:30 oracle@oel1
[oracle@oel1 ~]$ cd .ssh
[oracle@oel1 .ssh]$ ls
id_dsa id_dsa.pub id_rsa id_rsa.pub
[oracle@oel1 .ssh]$ cat id_rsa.pub >>authorized_keys
[oracle@oel1 .ssh]$ cat id_dsa.pub >>authorized_keys
[oracle@oel1 .ssh]$ ls
authorized_keys id_dsa id_dsa.pub id_rsa id_rsa.pub
[oracle@oel1 .ssh]$ ssh oracle@oel2 cat /home/oracle/.ssh/id_dsa.pub >>authorized_keys
The authenticity of host 'oel2 (128.192.0.2)' can't be established.
RSA key fingerprint is 24:51:79:a2:a3:a5:4d:ab:a1:98:cd:6b:ea:d6:58:cd.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'oel2,128.192.0.2' (RSA) to the list of known hosts.
oracle@oel2's password:
[oracle@oel1 .ssh]$ ssh oracle@oel2 cat /home/oracle/.ssh/id_dsa.pub >>authorized_keys
oracle@oel2's password:
[oracle@oel1 .ssh]$ scp authorized_keys oel2:/home/oracle/.ssh
oracle@oel2's password:
authorized_keys 100% 2024 2.0KB/s 00:00
10.在OEL1和OEl2上配置裸设备
[root@oel1 ~]# vi /etc/sysconfig/rawdevices
/dev/raw/raw1 /dev/sdb1
/dev/raw/raw2 /dev/sdb2
/dev/raw/raw3 /dev/sdc1
/dev/raw/raw4 /dev/sdc2
/dev/raw/raw5 /dev/sdc3
/dev/raw/raw6 /dev/sdc4
[root@oel1 ~]# service rawdevices restart
Assigning devices:
/dev/raw/raw1 --> /dev/sdb1
/dev/raw/raw1: bound to major 8, minor 17
/dev/raw/raw2 --> /dev/sdb2
/dev/raw/raw2: bound to major 8, minor 18
/dev/raw/raw3 --> /dev/sdc1
/dev/raw/raw3: bound to major 8, minor 33
/dev/raw/raw4 --> /dev/sdc2
/dev/raw/raw4: bound to major 8, minor 34
/dev/raw/raw5 --> /dev/sdc3
/dev/raw/raw5: bound to major 8, minor 35
/dev/raw/raw6 --> /dev/sdc4
/dev/raw/raw6: bound to major 8, minor 36
done
[root@oel1 ~]# raw -qa
/dev/raw/raw1: bound to major 8, minor 17
/dev/raw/raw2: bound to major 8, minor 18
/dev/raw/raw3: bound to major 8, minor 33
/dev/raw/raw4: bound to major 8, minor 34
/dev/raw/raw5: bound to major 8, minor 35
/dev/raw/raw6: bound to major 8, minor 36
[root@oel1 ~]# cat >>/etc/rc.local <<EOF
> chown -R oracle:dba /dev/raw/raw*
> EOF
[root@oel1 ~]# mkdir -p /u01/app/oracle/product/10.2/crs
[root@oel1 ~]# chown -R oracle:oinstall /u01
[root@oel1 ~]# su - oracle
[oracle@oel1 ~]$ cd $CRS_HOME
[oracle@oel1 crs]$ cd ..
[oracle@oel1 10.2]$ ls
crs
[oracle@oel1 10.2]$ mkdir -p db
下面就可以正式安装cluster软件了
[oracle@oel1 10.2]$ /mnt/cluvfy/runcluvfy.sh stage -pre crsinst -n oel1,oel2
