2 配置共享存储设备
编辑/etc/udev/rules.d/60-raw.rules ：
ACTION=="add",KERNEL=="/dev/sdb1",RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add",ENV{MAJOR}=="8",ENV{MINOR}=="17",RUN+="/bin/raw /dev/raw/raw1 %M %m"
ACTION=="add",KERNEL=="/dev/sdc1",RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add",ENV{MAJOR}=="8",ENV{MINOR}=="33",RUN+="/bin/raw /dev/raw/raw2 %M %m"
ACTION=="add",KERNEL=="/dev/sdd1",RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add",ENV{MAJOR}=="8",ENV{MINOR}=="49",RUN+="/bin/raw /dev/raw/raw3 %M %m"
ACTION=="add",KERNEL=="/dev/sde1",RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add",ENV{MAJOR}=="8",ENV{MINOR}=="65",RUN+="/bin/raw /dev/raw/raw4 %M %m"
KERNEL=="raw[1-4]",OWNER="oracle",GROUP="oinstall",MODE="640"
启动udev:
Start_udev
Ls –l /dev/raw
crw-r----- 1 oracle oinstall 162, 1 Jun 19 12:04 raw1
crw-r----- 1 oracle oinstall 162, 2 Jun 19 12:04 raw2
crw-r----- 1 oracle oinstall 162, 3 Jun 19 12:04 raw3
crw-r----- 1 oracle oinstall 162, 4 Jun 19 12:04 raw4
3 配置网络
Rac1:
接口 IP 掩码 网关
Eth0 192.168.0.2 255.255.255.0 192.168.0.1
Eth1 192.168.155.2 255.255.255.0
Rac2
接口 IP 掩码 网关
Eth0 192.168.0.3 255.255.255.0 192.168.0.1
Eth1 192.168.155.3 255.255.255.0
more /etc/hosts
192.168.155.1 ntpserver
127.0.0.1 localhost.localdomain localhost
192.168.0.2 rac1
192.168.0.3 rac2
192.168.155.2 rac1-priv
192.168.155.3 rac2-priv
192.168.0.4 rac1-vip
192.168.0.5 rac2-vip
4 建立节点间用户访问等效性
在rac1上：
# su-oracle
$mkdir~/.ssh
$chmod700~/.ssh
$ssh-keygen-t rsa
$ssh-keygen-t dsa
在rac2上：
$mkdir~/.ssh
$chmod700~/.ssh
$ssh-keygen -t rsa
$ssh-keygen -t dsa
在rac1上：
$ cat ~/.ssh/id_rsa.pub>>~/.ssh/authorized_keys
$ cat ~/.ssh/id_dsa.pub>>~/.ssh/authorized_keys
$ ssh rac2 cat ~/.ssh/id_rsa.pub>> ~/.ssh/authorized_keys
$ ssh rac2 cat ~/.ssh/id_dsa.pub>> ~/.ssh/authorized_keys
$ scp ~/.ssh/authorized_keys rac2:~/.ssh/authorized_keys
测试：
Rac1上：
$ssh rac1 date
$ssh rac2 date
$ssh rac1-priv date
$ssh rac2-priv date
切换至rac2执行
$ssh rac2 date
$ssh rac1 date
$ssh rac2-priv date
$ssh rac1-priv date
