p13390677_112040_Linux-x86-64_3of7.zip 解压生成grid目录

1.3 本地盘配置

将500GB的本地盘创建文件系统挂载到/u01目录下面，并修改/etc/fstab，让开机自动挂载/u01文件系统。

[root@db01 ~]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/vda1 20G 3.0G 16G 16% /

tmpfs 8.0G 132M 7.9G 2% /dev/shm

/dev/vdc1 493G 23G 445G 5% /u01

二 基础配置

基础配置需要在两个节点都要操作的。

2.1 网络配置

2.1.1 Host文件

#Public

192.168.0.2 db01

192.168.0.3 db02

#Virtual

192.168.0.102 db01-vip

192.168.0.103 db02-vip

#Private

192.168.101.2 db01-priv

192.168.101.3 db02-priv

#SCAN

192.168.0.100 db-scan

2.1.2 网络配置文件

节点1

[root@db01 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0

ONBOOT=yes

两个节点都要操作：

关闭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

2.2 创建用户

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

usermod -G dba oracle

usermod -G dba grid

usermod -aG asmadmin grid

[root@db02 software]# id oracle

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

[root@db02 software]# id grid

uid=501(grid) gid=501(oinstall) 组=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 设置profile

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

节点1：

Oracle用户

[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

节点2

Oracle用户：

[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

CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;

Grid用户：

[grid@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

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 配置路径

两台服务器都要配置：

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 安装rpm包

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

[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

2.5 sysctl.conf文件

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

设置生效：

/sbin/sysctl -p

2.6 limit文件

/etc/security/limits.conf 添加：

#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共享盘安装

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)

Login to [iface: default, target: iqn.2014-12.com.qingcloud.s2:sn.data, portal: 192.168.0.8,3260] successful.

7 配置开启自动启动识别

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"

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"

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, 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，用作数据。另外3块10GB的盘用作集群vote disk。

2.8 关闭ntp

Service ntpd stop

Chkconfig ntpd off

2.9 配置操作系统用户互信

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

三 预检查

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

四 图形化安装

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。

4.1 安装grid软件

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。

4.1.1执行脚本

节点1

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

[root@db02 ~]# /u01/app/11.2.0/grid/product/db_1/root.sh

[root@db02 ~]# su - grid

[grid@db02 ~]$ crs_stat -t

4.2 创建asm磁盘组

4.3 安装oracle软件

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

The following environment variables are set as:

ORACLE_OWNER= oracle

五 其他

5.1 start_udev重启自动运行

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

5.2 Ocr备份

[root@db01 ~]# /u01/app/11.2.0/grid/product/db_1/bin/ocrconfig -manualbackup

db02 2018/03/23 19:29:16 /u01/app/11.2.0/grid/product/db_1/cdata/db-cluster/backup_20180323_192916.ocr
