兩個節點都要操作：

關閉networkmanager

[root@i-zq8ytr3k network-scripts]# chkconfig NetworkManager --list

NetworkManager  0:off   1:off   2:on    3:on    4:on    5:on    6:off

[root@i-zq8ytr3k network-scripts]# chkconfig NetworkManager off

[root@i-zq8ytr3k network-scripts]# chkconfig NetworkManager --list

NetworkManager  0:off   1:off   2:off   3:off   4:off   5:off   6:off

重啟網路：

service network restart

關閉防火牆

service iptables stop

chkconfig iptables off

關閉selinux

修改：/etc/selinux/config 內容改為：SELINUX=disabled

setenforce  0

2.2 建立使用者

兩個節點都要操作：

groupadd -g 500 dba

 groupadd -g 501 oinstall

 groupadd -g 502 asmadmin

 useradd -g oinstall -u 500 oracle

 useradd -g oinstall -u 501 grid

 usermod -G dba  oracle

 usermod -G dba  grid

 usermod -aG asmadmin  grid

[root@db02 software]# id oracle

uid=500(oracle) gid=501(oinstall) 組=501(oinstall),500(dba)

[root@db02 software]# id grid

uid=501(grid) gid=501(oinstall) 組=501(oinstall),500(dba),502(asmadmin)

[root@db01 ~]# id oracle

uid=500(oracle) gid=501(oinstall) groups=501(oinstall),500(dba)

[root@db01 ~]# id grid

uid=501(grid) gid=501(oinstall) groups=501(oinstall),500(dba),502(asmadmin)

[root@db01 ~]#

2.2.1 設定profile

後續要將oracle的環境變數ORACLE_SID分別改為oadb1 和oadb2

節點1：

Oracle使用者

[oracle@db01 ~]$ cat .bash_profile

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

        . ~/.bashrc

fi

# User specific environment and startup programs

THREADS_FLAG=native; export THREADS_FLAG

PATH=$ORACLE_HOME/bin:$PATH; export PATHTHREADS_FLAG=native; export THREADS_FLAG

PATH=$ORACLE_HOME/bin:$PATH; export PATH

節點2

Oracle使用者：

[oracle@db02 ~]$ cat .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

Grid使用者：

[grid@db02 ~]$ cat .bash_profile

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

        . ~/.bashrc

fi

# User specific environment and startup programs

THREADS_FLAG=native; export THREADS_FLAG

PATH=$ORACLE_HOME/bin:$PATH; export PATHTHREADS_FLAG=native; export THREADS_FLAG

PATH=$ORACLE_HOME/bin:$PATH; export PATH

2.3 配置路徑

兩臺伺服器都要配置：

mkdir -p /u01/app

 chown -R root:oinstall  /u01/app

 mkdir  -p  /u01/app/11.2.0/ 

 mkdir  -p  /u01/app/grid/ 

 mkdir  -p  /u01/app/oracle/

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

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

 chown  -R  oracle:oinstall /u01/app/oracle

2.4 安裝rpm包

配置本地映象

將iso檔案掛載

mount -t iso9660 -o loop /u01/software/V52218-01-OEL-6.6.iso /u01/software/mnt

重新命名之前的檔案

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

[Server]

name=Oracle Linux $releasever Beta - $basearch - Server

baseurl=file:///u01/software/mnt

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle

安裝rpm

yum install gcc compat-libstdc++-33 elfutils-libelf-devel gcc-c++ libaio-devel libstdc++-devel ksh  -y

後續根據實際情況也許需要安裝一些新的包，都可以在/u01/software/mnt/Packages中找到

2.5 sysctl.conf檔案

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

fs.file-max = 6815744

net.ipv4.ip_local_port_range = 9000 65000

net.core.rmem_default = 1048576

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

vm.min_free_kbytes= 1048576

fs.aio-max-nr= 1048576

設定生效：

/sbin/sysctl -p

2.6 limit檔案

/etc/security/limits.conf 新增：

#add by oracle

oracle  hard nofile 65536

oracle   soft nofile 4096

oracle   hard nproc 16384

oracle   soft nproc 2047

grid hard nofile 65536

grid soft nofile 1024

grid hard nproc 16384

grid soft nproc 2047

2.7共享盤安裝

在雲平臺上分配共享儲存之後，最好在介面上設定可以訪問共享儲存的客戶端，本次設定的是：iqn.2014-12.com.qingcloud:e594a0ee9b82

和iqn.2014-12.com.qingcloud:5ba958139a1

1 安裝工具包

yum install -y iscsi-initiator-utils

2 根據字首生成客戶端id

iscsi-iname -p iqn.2014-12.com.qingcloud

結果：

[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 修改配置檔案

/etc/iscsi/initiatorname.iscsi  修改為下面的資訊（名稱是介面上看到的）

節點1:

[root@db01 ~]# cat /etc/iscsi/initiatorname.iscsi

InitiatorName=iqn.2014-12.com.qingcloud:5ba958139a1

節點2：

[root@db02 ~]# cat /etc/iscsi/initiatorname.iscsi

InitiatorName=iqn.2014-12.com.qingcloud:e594a0ee9b82

4 客戶端發現（兩個伺服器都要配置）

[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 註冊（兩個伺服器都要配置）

[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)

7 配置開啟自動啟動識別

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能識別的盤

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

最後檔案生成的/etc/udev/rules.d/99-oracle-asmdevices.rules檔案是：

[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"

KERNEL=="sd*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="36001405e371bbbb031b4547b5fe217d1", NAME="asm-disk2",  OWNER="grid",  GROUP="asmadmin", MODE="0660"

KERNEL=="sd*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="36001405ff11eeac99ac40f69e34a3ec5", NAME="asm-disk3",  OWNER="grid",  GROUP="asmadmin", MODE="0660"

KERNEL=="sd*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600140517aafddef37c4305a3e6930ee", NAME="asm-disk4",  OWNER="grid",  GROUP="asmadmin", MODE="0660"

檢視生成的裝置符號

[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, 32 Mar 23 19:12 /dev/asm-disk3

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, 32 Mar 23 19:12 /dev/asm-disk3

brw-rw---- 1 grid asmadmin 8, 48 Mar 23 19:12 /dev/asm-disk4

其中asm-disk2 是500GB，用作資料。另外3塊10GB的盤用作叢集vote disk。

2.8 關閉ntp

Service ntpd stop

Chkconfig ntpd off

2.9 配置作業系統使用者互信

修改ssh配置檔案：/etc/ssh/ssh_config，註釋下面兩行

        #StrictHostKeyChecking no

        #UserKnownHostsFile /dev/null

Oracle 和grid使用者都要操作

mkdir ~/.ssh

 chmod 700 ~/.ssh

 ssh-keygen -t rsa

 ssh-keygen -t dsa

在節點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

之後分別使用grid、oracle使用者在兩個節點都執行：

Ssh db01

ssh db02

ssh db01-priv

ssh db02-priv

按照提示輸入yes，不輸入密碼能正常登陸表示正常

三 預檢查

節點1，使用grid使用者，切換至目錄：

/u01/software/u01，執行命令：

./runcluvfy.sh stage -pre crsinst -n db01,db02  -fixup -verbose

結果如下，按照需求再安裝rpm，讓failed成功：

[grid@db01 grid]$  ./runcluvfy.sh stage -pre crsinst -n db01,db02  -fixup -verbose

四 圖形化安裝

為避免網路中途掉線，所有圖形化均在web控制檯上分別使用grid、oracle使用者登陸db01進行操作。

4.1 安裝grid軟體

使用grid使用者登陸db01，切換至目錄：

/u01/software/grid

執行./runInstaller

選擇大小為10G的/dev/asm-disk1, /dev/asm-disk3,/dev/asm-disk4

這裡需要點選“change discovery path”，設定路徑為/dev/asm*

在進行環境檢查時，會報錯

這個警告在青雲平臺也有說明：

註解 grid安裝環境檢查指令碼在Oracle Linux 6上面的一個bug導致錯誤”PRVF-9802”無法解決，具體原因請見 Debug Cluvfy error ERROR: PRVF-9802 。

勾選忽略這個警告。

彈出指令碼分別使用root在兩個伺服器執行：

/u01/app/oraInventory/orainstRoot.sh

/u01/app/11.2.0/grid/product/db_1/root.sh

第二個指令碼執行會比較好時間，大概20分鐘。

4.1.1執行指令碼

節點1

[root@db01 ~]# /u01/app/oraInventory/orainstRoot.sh

[root@db02 ~]# su - grid

[grid@db02 ~]$ crs_stat -t

4.2 建立asm磁碟組

4.3 安裝oracle軟體

Oracle使用者登陸，切換至目錄：

/u01/software/database

執行./runInstaller

Root登陸兩臺機器分別執行指令碼：

[root@db01 ~]# /u01/app/oracle/product/11.2.0/db_1/root.sh

五 其他

5.1 start_udev重啟自動執行

檢視start_udev是否開機自動執行，修改/etc/rc.d/rc.sysinit檔案

新增：/sbin/start_udev
