两个节点都要操作：
关闭networkmanager

NetworkManager 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@i-zq8ytr3k network-scripts]# chkconfig NetworkManager off

重启网络：
service network restart
关闭防火墙
service iptables stop
chkconfig iptables off
关闭selinux
修改：/etc/selinux/config 内容改为：SELINUX=disabled
setenforce 0
两个节点都要操作：
groupadd -g 500 dba
groupadd -g 501 oinstall
groupadd -g 502 asmadmin
useradd -g oinstall -u 500 oracle
useradd -g oinstall -u 501 grid

后续要将oracle的环境变量ORACLE_SID分别改为oadb1 和oadb2

mkdir -p /u01/app/grid/

chown -R grid:oinstall /u01/app/11.2.0
chown -R grid:oinstall /u01/app/grid

配置本地镜像
将iso文件挂载
mount -t iso9660 -o loop /u01/software/V52218-01-OEL-6.6.iso /u01/software/mnt
重命名之前的文件
Mv /etc/yum.repos.d/public-yum-ol6.repo /etc/yum.repos.d/public-yum-ol6.repo_bak
[root@db02 ~]# cat /etc/yum.repos.d/public-yum-ol6.repo

安装rpm
yum install gcc compat-libstdc++-33 elfutils-libelf-devel gcc-c++ libaio-devel libstdc++-devel ksh -y
后续根据实际情况也许需要安装一些新的包，都可以在/u01/software/mnt/Packages中找到
修改/etc/sysctl.conf
新加
##add by oracle
kernel.shmmax = 4294967295
kernel.shmall = 2097152
kernel.shmmni = 4096
kernel.sem = 1100 32000 100 128

设置生效：

在云平台上分配共享存储之后，最好在界面上设置可以访问共享存储的客户端，本次设置的是：iqn.2014-12.com.qingcloud:e594a0ee9b82
和iqn.2014-12.com.qingcloud:5ba958139a1
1 安装工具包
yum install -y iscsi-initiator-utils
2 根据前缀生成客户端id
iscsi-iname -p iqn.2014-12.com.qingcloud
结果：
[root@db02 ~]# iscsi-iname -p iqn.2014-12.com.qingcloud
iqn.2014-12.com.qingcloud:e594a0ee9b82
[root@db01 ~]# iscsi-iname -p iqn.2014-12.com.qingcloud
iqn.2014-12.com.qingcloud:5ba958139a1
3 修改配置文件
/etc/iscsi/initiatorname.iscsi 修改为下面的信息（名称是界面上看到的）
节点1:
[root@db01 ~]# cat /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.2014-12.com.qingcloud:5ba958139a1
节点2：
[root@db02 ~]# cat /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.2014-12.com.qingcloud:e594a0ee9b82
4 客户端发现（两个服务器都要配置）
[root@db01 iscsi]# iscsiadm -m discovery -t st -p 192.168.0.8
Starting iscsid: [ OK ]
192.168.0.8:3260,1 iqn.2014-12.com.qingcloud.s2:sn.data
[root@i-zq8ytr3k iscsi]# iscsiadm -m node
192.168.0.8:3260,1 iqn.2014-12.com.qingcloud.s2:sn.data
5 注册（两个服务器都要配置）
[root@db01 iscsi]# iscsiadm -m node -T iqn.2014-12.com.qingcloud.s2:sn.data -p 192.168.0.8 --login
Logging in to [iface: default, target: iqn.2014-12.com.qingcloud.s2:sn.data, portal: 192.168.0.8,3260] (multiple)

iscsiadm -m node -T iqn.2014-12.com.qingcloud.s2:sn.data -p 192.168.0.8 --op update -n node.startup -v automatic
8 配置asm能识别的盘
echo "options=--whitelisted --replace-whitespace">/etc/scsi_id.config
rm -f /etc/udev/rules.d/99-oracle-asmdevices.rules
i=1
id=''
for x in a b c d
do
id=`scsi_id --whitelisted --replace-whitespace --device=/dev/sd$x`
echo "KERNEL==\"sd*\", SUBSYSTEM==\"block\", PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\", RESULT==\"$id\", NAME=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\"">>/etc/udev/rules.d/99-oracle-asmdevices.rules
let i++
done
/sbin/start_udev
最后文件生成的/etc/udev/rules.d/99-oracle-asmdevices.rules文件是：
[root@db01 ~]# cat /etc/udev/rules.d/99-oracle-asmdevices.rules
KERNEL=="sd*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="36001405745529a22afc4f8fb1a685e36", NAME="asm-disk1", OWNER="grid", GROUP="asmadmin", MODE="0660"

查看生成的设备符号
[root@db01 ~]# ll /dev/asm*
brw-rw---- 1 grid asmadmin 8, 0 Mar 23 19:12 /dev/asm-disk1
brw-rw---- 1 grid asmadmin 8, 16 Mar 23 19:12 /dev/asm-disk2

brw-rw---- 1 grid asmadmin 8, 48 Mar 23 19:12 /dev/asm-disk4
[root@db02 ~]# ll /dev/asm*
brw-rw---- 1 grid asmadmin 8, 0 Mar 23 19:12 /dev/asm-disk1
brw-rw---- 1 grid asmadmin 8, 16 Mar 23 19:12 /dev/asm-disk2

brw-rw---- 1 grid asmadmin 8, 48 Mar 23 19:12 /dev/asm-disk4
其中asm-disk2 是500GB，用作数据。另外3块10GB的盘用作集群vote disk。
Service ntpd stop
Chkconfig ntpd off
修改ssh配置文件：/etc/ssh/ssh_config，注释下面两行
#StrictHostKeyChecking no
#UserKnownHostsFile /dev/null
Oracle 和grid用户都要操作
mkdir ~/.ssh
chmod 700 ~/.ssh
ssh-keygen -t rsa
ssh-keygen -t dsa
在节点1：
$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
$ ssh db02 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
$ ssh db02 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
$ scp ~/.ssh/authorized_keys db02:~/.ssh/authorized_keys
之后分别使用grid、oracle用户在两个节点都运行：
Ssh db01
ssh db02
ssh db01-priv
ssh db02-priv
按照提示输入yes，不输入密码能正常登陆表示正常
节点1，使用grid用户，切换至目录：
/u01/software/u01，运行命令：
./runcluvfy.sh stage -pre crsinst -n db01,db02 -fixup -verbose
结果如下，按照需求再安装rpm，让failed成功：
[grid@db01 grid]$ ./runcluvfy.sh stage -pre crsinst -n db01,db02 -fixup -verbose
为避免网络中途掉线，所有图形化均在web控制台上分别使用grid、oracle用户登陆db01进行操作。
使用grid用户登陆db01，切换至目录：
/u01/software/grid
执行./runInstaller
选择大小为10G的/dev/asm-disk1, /dev/asm-disk3,/dev/asm-disk4
这里需要点击“change discovery path”，设置路径为/dev/asm*
在进行环境检查时，会报错
这个警告在青云平台也有说明：
注解 grid安装环境检查脚本在Oracle Linux 6上面的一个bug导致错误”PRVF-9802”无法解决，具体原因请见Debug Cluvfy error ERROR: PRVF-9802。
勾选忽略这个警告。
弹出脚本分别使用root在两个服务器执行：
/u01/app/oraInventory/orainstRoot.sh
/u01/app/11.2.0/grid/product/db_1/root.sh
第二个脚本执行会比较好时间，大概20分钟。

[root@db02 ~]# su - grid
[grid@db02 ~]$ crs_stat -t
Oracle用户登陆，切换至目录：
/u01/software/database
运行./runInstaller
Root登陆两台机器分别执行脚本：
[root@db01 ~]# /u01/app/oracle/product/11.2.0/db_1/root.sh
Performing root user operation for Oracle 11g

查看start_udev是否开机自动运行，修改/etc/rc.d/rc.sysinit文件
添加：/sbin/start_udev
