注:这些软件小麦苗已上传到腾讯微云(http://blog.itpub.net/26736162/viewspace-1624453/),各位朋友可以去下载。另外,小麦苗已经将安装好的虚拟机上传到了云盘,里边已集成了rlwrap软件。

1.1.2  IP地址规划

Oracle 11g开始,共7IP地址,2块网卡,其中publicvipscan都在同一个网段,private在另一个网段,主机名不要包含下横线,如:RAC_01是不允许的;通过执行ifconfig -a检查2个节点的网络设备名字是否一致。另外,在安装之前,公网、私网共4IP可以ping通,其它3个不能ping通才是正常的。

1.2  操作系统配置部分

1.2.1  安装主机或虚拟机

安装步骤略。安装一台虚拟机,然后复制改名,如下:

技术分享 

也可以下载小麦苗已经安装好的虚拟机环境。

1.2.2  修改主机名

修改2个节点的主机名为raclhr-12cR1-N1和raclhr-12cR1-N2

vi /etc/sysconfig/network

HOSTNAME=raclhr-12cR1-N1

hostname raclhr-12cR1-N1

 

 

1.2.3  网络配置

1.2.3.1  添加虚拟网卡

技术分享 

添加2块网卡,VMnet8为公有网卡,VMnet2位私有网卡,如下所示:

技术分享 

1.2.3.2  配置IP地址

chkconfig NetworkManager off

chkconfig network on

service NetworkManager stop

service network start

 

2个节点上分别执行如下的操作,在节点2上配置IP的时候注意将IP地址修改掉。

第一步,配置公网和私网的IP地址:

配置公网:vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

IPADDR=192.168.59.160

NETMASK=255.255.255.0

NETWORK=192.168.59.0

BROADCAST=192.168.59.255

GATEWAY=192.168.59.2

ONBOOT=yes

USERCTL=no

BOOTPROTO=static

TYPE=Ethernet

IPV6INIT=no

 

配置私网:vi /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1

IPADDR=192.168.2.100

NETMASK=255.255.255.0

NETWORK=192.168.2.0

BROADCAST=192.168.2.255

GATEWAY=192.168.2.1

ONBOOT=yes

USERCTL=no

BOOTPROTO=static

TYPE=Ethernet

IPV6INIT=no

 

第二步,将/etc/udev/rules.d/70-persistent-net.rules中的内容清空,

第三步,重启主机。

[root@raclhr-12cR1-N1 ~]# ip a

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    inet 127.0.0.1/8 scope host lo

    inet6 ::1/128 scope host

       valid_lft forever preferred_lft forever

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000

    link/ether 00:0c:29:d9:43:a7 brd ff:ff:ff:ff:ff:ff

    inet 192.168.59.160/24 brd 192.168.59.255 scope global eth0

    inet6 fe80::20c:29ff:fed9:43a7/64 scope link

       valid_lft forever preferred_lft forever

3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000

    link/ether 00:0c:29:d9:43:b1 brd ff:ff:ff:ff:ff:ff

    inet 192.168.2.100/24 brd 192.168.2.255 scope global eth1

    inet6 fe80::20c:29ff:fed9:43b1/64 scope link

       valid_lft forever preferred_lft forever

4: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN

    link/ether 52:54:00:68:da:bb brd ff:ff:ff:ff:ff:ff

    inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0

5: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 500

    link/ether 52:54:00:68:da:bb brd ff:ff:ff:ff:ff:ff

 

 

1.2.3.3  关闭防火墙

2个节点上分别执行如下语句:

service iptables stop

service ip6tables stop

chkconfig iptables off

chkconfig ip6tables off

 

chkconfig iptables --list

chkconfig iptables off   ---永久

service iptables stop    ---临时

/etc/init.d/iptables status    ----会得到一系列信息,说明防火墙开着。

/etc/rc.d/init.d/iptables stop   ----------关闭防火墙

LANG=en_US

setup ----------图形界面

 

1.2.3.4  禁用selinux

修改/etc/selinux/config

编辑文本中的SELINUX=enforcingSELINUX=disabled

[root@raclhr-12cR1-N1 ~]# more /etc/selinux/config

 

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

#     enforcing - SELinux security policy is enforced.

#     permissive - SELinux prints warnings instead of enforcing.

#     disabled - No SELinux policy is loaded.

SELINUX=disabled

# SELINUXTYPE= can take one of these two values:

#     targeted - Targeted processes are protected,

#     mls - Multi Level Security protection.

SELINUXTYPE=targeted

[root@raclhr-12cR1-N1 ~]#

临时关闭(不用重启机器):

setenforce 0

 

 

查看SELinux状态:

1、/usr/sbin/sestatus -v  ##如果SELinux status参数为enabled即为开启状态

SELinux status:  enabled

2、getenforce  ##也可以用这个命令检查

[root@raclhr-12cR1-N1 ~] /usr/sbin/sestatus -v

SELinux status:                 disabled

[root@raclhr-12cR1-N1 ~] getenforce

Disabled

[root@raclhr-12cR1-N1 ~] 

 

1.2.3.5  修改/etc/hosts文件

2个节点均配置相同,如下:

[root@raclhr-12cR1-N2 ~]# more /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

 

#Public IP

1.2.5  添加组和用户

1.2.5.1  添加oracle和grid用户

Oracle 11gR2开始,安装RAC需要安装 Oracle Grid Infrastructure 软件、Oracle数据库软件,其中Grid软件等同于Oracle 10gClusterware集群件。Oracle建议以不同的用户分别安装Grid Infrastructure软件、Oracle数据库软件一般以grid用户安装Grid Infrastructureoracle用户安装Oracle数据库软件。gridoracle用户需要属于不同的用户组。在配置RAC时,还要求这两个用户在RAC的不同节点上uidgid要一致。

ü 创建5个组dbaoinstall分别做为OSDBA组,Oracle Inventory组;asmdba,asmoperasmadmin作为ASM磁盘管理组。

ü 创建2个用户oracle, grid,oracle属于dba,oinstall,oraoper,asmdba组,grid属于asmadmin,asmdba,asmoper,oraoper,dbaoinstall做为用户的primary group

ü 上述创建的所有用户和组在每台机器上的名称和对应ID号,口令,以及属组关系和顺序必须保持一致。grid和oracle密码不过期。

 

创建组:

groupadd -g 1000 oinstall

groupadd -g 1001 dba

groupadd -g 1002 oper

groupadd -g 1003 asmadmin

groupadd -g 1004 asmdba

groupadd -g 1005 asmoper

 

创建grid和oracle用户:

useradd -u 1000 -g oinstall -G asmadmin,asmdba,asmoper,dba -d /home/grid -m grid

useradd -u 1001 -g oinstall -G dba,asmdba -d /home/oracle -m oracle

 

如果oracle用户已经存在,则:

usermod -g oinstall -G dba,asmdba u 1001 oracle

 

oraclegrid用户设密码:

passwd oracle

passwd grid

 

设置密码永不过期:

chage -M -1 oracle

chage -M -1 grid

chage -l oracle

chage -l grid

 

检查:

[root@raclhr-12cR1-N1 ~]# id grid

uid=1000(grid) gid=1000(oinstall) groups=1000(oinstall),1001(dba),1003(asmadmin),1004(asmdba),1005(asmoper)

[root@raclhr-12cR1-N1 ~]# id oracle

uid=1001(oracle) gid=1000(oinstall) groups=1000(oinstall),1001(dba),1004(asmdba)

[root@raclhr-12cR1-N1 ~]#

 

1.2.5.2  创建安装目录

? GRID 软件的 ORACLE_HOME 不能是 ORACLE_BASE 的子目录

 

--在2个节点均创建,root用户下创建目录:

mkdir -p /u01/app/oracle

mkdir -p /u01/app/grid

mkdir -p /u01/app/12.1.0/grid

mkdir -p /u01/app/oracle/product/12.1.0/dbhome_1

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

chown -R grid:oinstall /u01/app/12.1.0

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

chmod -R 775 /u01

 

mkdir -p /u01/app/oraInventory

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

chmod -R 775 /u01/app/oraInventory

 

1.2.5.3  配置gridoracle用户的环境变量文件

修改gird、oracle用户的.bash_profile文件,oracle账号登陆,编辑.bash_profile

或者在root直接编辑:

vi /home/oracle/.bash_profile

vi /home/grid/.bash_profile

 

Oracle用户:

umask 022

export ORACLE_SID=lhrrac1

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/dbhome_1

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"

export TMP=/tmp

export TMPDIR=$TMP

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

 

 

export EDITOR=vi

export TNS_ADMIN=$ORACLE_HOME/network/admin

export ORACLE_PATH=.:$ORACLE_BASE/dba_scripts/sql:$ORACLE_HOME/rdbms/admin

export SQLPATH=$ORACLE_HOME/sqlplus/admin

 

 

#export NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK" --AL32UTF8 SELECT userenv(‘LANGUAGE‘) db_NLS_LANG FROM DUAL;

export NLS_LANG="AMERICAN_CHINA.ZHS16GBK"

 

alias sqlplus=‘rlwrap sqlplus‘

alias rman=‘rlwrap rman‘

alias asmcmd=‘rlwrap asmcmd‘

 

 

 

grid用户:

umask 022

export ORACLE_SID=+ASM1

export ORACLE_BASE=/u01/app/grid

export ORACLE_HOME=/u01/app/12.1.0/grid

export LD_LIBRARY_PATH=$ORACLE_HOME/lib

export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"

export PATH=$ORACLE_HOME/bin:$PATH

alias sqlplus=‘rlwrap sqlplus‘

alias asmcmd=‘rlwrap asmcmd‘

 

 

 注意:另外一台数据库实例名须做相应修改:

Oracle:export  ORACLE_SID=lhrrac2

grid:export ORACLE_SID=+ASM2

1.2.5.4  配置root用户的环境变量

vi /etc/profile

export ORACLE_HOME=/u01/app/12.1.0/grid

export PATH=$PATH:$ORACLE_HOME/bin

配置本地yum源,也可以将整个光盘的内容拷贝到本地里,然后如下配置:

rpm -ivh deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm

rpm -ivh python-deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm

rpm -ivh createrepo-0.9.9-18.el6.noarch.rpm

createrepo .

 

 

小麦苗直接使用了光盘,并没有配置这个。

1.2.6.2  安装缺失的包

yum install compat-libstdc++*

yum install libaio-devel*

yum install ksh*

 

最后重新检查,确保所有的包已安装。需要注意的是,有的时候由于版本的问题导致检查有问题,所以需要用rpm -qa | grep libstdc 来检查。

1.2.10  配置NTP

Network Time Protocol Setting

 You have two options for time synchronization: an operating system configured network time protocol (NTP), or Oracle Cluster Time Synchronization Service.

 Oracle Cluster Time Synchronization Service is designed for organizations whose cluster servers are unable to access NTP services.

 If you use NTP, then the Oracle Cluster Time Synchronization daemon (ctssd) starts up in observer mode. If you do not have NTP daemons, then ctssd starts up in active mode and synchronizes time among cluster members without contacting an external time server..

 

可以采用操作系统的NTP服务,也可以使用Oracle自带的服务ctss,如果ntp没有启用,Oracle会自动启用自己的ctssd进程。

oracle 11gR2 RAC开始使用Cluster Time Synchronization Service(CTSS)同步各节点的时间,当安装程序发现NTP协议处于非活动状态时,安装集群时间同步服务将以活动模式自动进行安装并通过所有节点的时间。如果发现配置了 NTP,则以观察者模式启动集群时间同步服务,Oracle Clusterware 不会在集群中进行活动的时间同步。

 

root 用户双节点运行:

/sbin/service ntpd stop

mv /etc/ntp.conf /etc/ntp.conf.bak

service ntpd status

chkconfig ntpd off

 

1.3  配置共享存储

这个是重点,也是最容易出错的地方,这次是小麦苗第二次虚拟机上安装RAC环境,有的内容不再详述。

 

1.3.1  添加共享磁盘

1.3.1.1  第一步:创建共享磁盘

该步骤可以用cmd命令也可以用图形界面,本文采用命令行进行添加。

cmd 中进入 WMware Workstation安装目录,执行命令创建磁盘:

C:

cd  C:\Program Files (x86)\VMware\VMware Workstation

vmware-vdiskmanager.exe -c -s 6g -a lsilogic -t 2 "E:\My Virtual Machines\rac12cR1\sharedisk\ocr_vote.vmdk"

vmware-vdiskmanager.exe -c -s 10g -a lsilogic -t 2 "E:\My Virtual Machines\rac12cR1\sharedisk\data.vmdk"

vmware-vdiskmanager.exe -c -s 10g -a lsilogic -t 2 "E:\My Virtual Machines\rac12cR1\sharedisk\fra.vmdk"

 

 

D:\Users\xiaomaimiao>C:

 

C:\>cd  C:\Program Files (x86)\VMware\VMware Workstation

C:\Program Files (x86)\VMware\VMware Workstation>vmware-vdiskmanager.exe -c -s 6g -a lsilogic -t 2 "E:\My Virtual Machines\rac12cR1\sharedisk\ocr_vote.vmdk"

Creating disk ‘E:\My Virtual Machines\rac12cR1\sharedisk\ocr_vote.vmdk‘

  Create: 100% done.

Virtual disk creation successful.

 

C:\Program Files (x86)\VMware\VMware Workstation>vmware-vdiskmanager.exe -c -s 10g -a lsilogic -t 2 "E:\My Virtual Machines\rac12cR1\sharedisk\data.vmdk"

Creating disk ‘E:\My Virtual Machines\rac12cR1\sharedisk\data.vmdk‘

  Create: 100% done.

Virtual disk creation successful.

 

C:\Program Files (x86)\VMware\VMware Workstation>vmware-vdiskmanager.exe -c -s 10g -a lsilogic -t 2 "E:\My Virtual Machines\rac12cR1\sharedisk\fra.vmdk"

Creating disk ‘E:\My Virtual Machines\rac12cR1\sharedisk\fra.vmdk‘

  Create: 100% done.

Virtual disk creation successful.

 

 

技术分享 

注意:12c R1的OCR磁盘组最少需要5501MB的空间。

[INS-30515] Insufficient space available in the selected disks.

Cause - Insufficient space available in the selected Disks. At least, 5,501 MB of free space is required. 

Action - Choose additional disks such that the total size should be at least 5,501 MB.

 

技术分享 

 

1.3.1.2  第二步:修改配置文件

关闭两台虚拟机,用记事本打开 虚拟机名字.vmx,即打开配置文件,2个节点都需要修改。

 

添加以下内容,其中,scsix:y 表示第x个总线上的第y个设备:

#shared disks configure

disk.EnableUUID="TRUE"

disk.locking = "FALSE"

scsi1.shared = "TRUE"

diskLib.dataCacheMaxSize = "0"

diskLib.dataCacheMaxReadAheadSize = "0"

diskLib.dataCacheMinReadAheadSize = "0"

diskLib.dataCachePageSize= "4096"

diskLib.maxUnsyncedWrites = "0"

 

scsi1.present = "TRUE"

scsi1.virtualDev = "lsilogic"

scsil.sharedBus = "VIRTUAL"

scsi1:0.present = "TRUE"

scsi1:0.mode = "independent-persistent"

scsi1:0.fileName = "..\sharedisk\ocr_vote.vmdk"

scsi1:0.deviceType = "disk"

scsi1:0.redo = ""

scsi1:1.present = "TRUE"

scsi1:1.mode = "independent-persistent"

scsi1:1.fileName = "..\sharedisk\data.vmdk"

scsi1:1.deviceType = "disk"

scsi1:1.redo = ""

scsi1:2.present = "TRUE"

scsi1:2.mode = "independent-persistent"

scsi1:2.fileName = "..\sharedisk\fra.vmdk"

scsi1:2.deviceType = "disk"

scsi1:2.redo = ""

 

如果报有的参数不存在的错误,那么请将虚拟机的兼容性设置到Workstation 9.0

技术分享 

1.3.1.3  第三步:重新打开VMware Workstation

关闭 VMware Workstation 软件重新打开,此时看到共享磁盘正确加载则配置正确,这里尤其注意第二个节点,2个节点的硬盘配置网络适配器的配置应该是一样的,若不一样请检查配置。

技术分享 

然后开启2台虚拟机。

1.3.2  设置共享磁盘

1.3.2.1  配置udev绑定的scsi_id

注意以下两点:

 首先切换到root用户下

 2个节点上获取的uuid应该是一样的,不一样的话说明之前的配置有问题

1、不同的操作系统,scsi_id命令的位置不同。

[root@raclhr-12cR1-N1 ~]# cat /etc/issue

Red Hat Enterprise Linux Server release 6.5 (Santiago)

Kernel \r on an \m

 

[root@raclhr-12cR1-N1 ~]# which scsi_id

/sbin/scsi_id

[root@raclhr-12cR1-N1 ~]#

 

注意:rhel 6之后只支持 --whitelisted --replace-whitespace  参数,之前的 -g -u -s 参数已经不支持了。

2、编辑 /etc/scsi_id.config 文件,如果该文件不存在,则创建该文件并添加如下行:

[root@raclhr-12cR1-N1 ~]#  echo "options=--whitelisted --replace-whitespace" > /etc/scsi_id.config

[root@raclhr-12cR1-N1 ~]# more /etc/scsi_id.config

options=--whitelisted --replace-whitespace

[root@raclhr-12cR1-N1 ~]#

3、获取uuid

scsi_id --whitelisted --replace-whitespace --device=/dev/sdc

scsi_id --whitelisted --replace-whitespace --device=/dev/sdd

scsi_id --whitelisted --replace-whitespace --device=/dev/sde

 

[root@raclhr-12cR1-N1 ~]# scsi_id --whitelisted --replace-whitespace --device=/dev/sdc

36000c29fd84cfe0767838541518ef8fe

[root@raclhr-12cR1-N1 ~]# scsi_id --whitelisted --replace-whitespace --device=/dev/sdd

36000c29c0ac0339f4b5282b47c49285b

[root@raclhr-12cR1-N1 ~]# scsi_id --whitelisted --replace-whitespace --device=/dev/sde

36000c29e4652a45192e32863956c1965

 

2个节点获取到的值应该是一样的。

1.3.2.2  创建并配置udev rules文件

直接运行如下的脚本:

mv /etc/udev/rules.d/99-oracle-asmdevices.rules /etc/udev/rules.d/99-oracle-asmdevices.rules_bk

for i in c d e ;

do

echo "KERNEL==\"sd*\", BUS==\"scsi\", PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\",RESULT==\"`scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`\",NAME=\"asm-disk$i\",OWNER=\"grid\",GROUP=\"asmadmin\",MODE=\"0660\"" >> /etc/udev/rules.d/99-oracle-asmdevices.rules

done

start_udev

 

或使用如下的代码分步执行获取:

for i in c d e ;

do

echo "KERNEL==\"sd*\", BUS==\"scsi\", PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\",RESULT==\"`scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`\",NAME=\"asm-disk$i\",OWNER=\"grid\",GROUP=\"asmadmin\",MODE=\"0660\""

done

 

[root@raclhr-12cR1-N1 ~]# for i in c d e ;

> do

> echo "KERNEL==\"sd*\", BUS==\"scsi\", PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\",RESULT==\"`scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`\",NAME=\"asm-disk$i\",OWNER=\"grid\",GROUP=\"asmadmin\",MODE=\"0660\""

> done

KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c29fd84cfe0767838541518ef8fe",NAME="asm-diskc",OWNER="grid",GROUP="asmadmin",MODE="0660"

KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c29c0ac0339f4b5282b47c49285b",NAME="asm-diskd",OWNER="grid",GROUP="asmadmin",MODE="0660"

[root@raclhr-12cR1-N1 ~]#

 

编辑vi /etc/udev/rules.d/99-oracle-asmdevices.rules加入上边的脚本生成的内容。

这里需要注意,一个KERNEL就是一行,不能换行的。

在安装12cR1 GRID RAC之前经常会需要运行集群验证工具CVUCluster Verification Utility),该工具执行系统检查,确认当前的配置是否满足要求

首先判断是否安装了cvuqdisk包:

rpm -qa cvuqdisk

如果没有安装,那么在2个节点上都执行如下命令进行安装该包

export CVUQDISK_GRP=oinstall

cd /soft/grid/rpm/

rpm -ivh  cvuqdisk-1.0.9-1.rpm

 

[root@raclhr-12cR1-N1 soft]# cd /soft/grid/

[root@raclhr-12cR1-N1 grid]# ll

total 80

drwxr-xr-x  4 root root  4096 Jan 16 17:04 install

drwxr-xr-x 14 root root  4096 Jul  7  2014 stage

-rwxr-xr-x  1 root root   500 Feb  7  2013 welcome.html

[root@raclhr-12cR1-N1 grid]# cd rpm

[root@raclhr-12cR1-N1 rpm]# ll

-rwxr-xr-x 1 root root 8976 Jul  1  2014 cvuqdisk-1.0.9-1.rpm

[root@raclhr-12cR1-N1 rpm]# export CVUQDISK_GRP=oinstall

[root@raclhr-12cR1-N1 rpm]# cd /soft/grid/rpm/

[root@raclhr-12cR1-N1 rpm]# rpm -ivh  cvuqdisk-1.0.9-1.rpm

Preparing...                ########################################### [100%]

[root@raclhr-12cR1-N1 rpm]# rpm -qa cvuqdisk

cvuqdisk-1.0.9-1.x86_64

[root@raclhr-12cR1-N1 rpm]#

[root@raclhr-12cR1-N1 sshsetup]# ls -l /usr/sbin/cvuqdisk

-rwsr-xr-x 1 root oinstall 11920 Jul  1  2014 /usr/sbin/cvuqdisk

[root@raclhr-12cR1-N1 sshsetup]#

 

 

传输到第2个节点上进行安装:

scp cvuqdisk-1.0.9-1.rpm root@192.168.59.161:/tmp

export CVUQDISK_GRP=oinstall

rpm -ivh  /tmp/cvuqdisk-1.0.9-1.rpm

 

1.5.2  SSH互信建立ssh等效性

所谓用户等价,就是以Oracle用户从一个节点连接到另一个节点时,不需要输入密码。Oracle GIDB的安装过程都是先在一个节点安装,然后安装程序自动把本地安装好的内容复制到远程相同的目录下,这是一个后台拷贝过程,用户没有机会输入密码验证身份,必须进行配置。

 

虽然在安装软件的过程中,Oracle会自动配置SSH对等性,不过还是建议在安装软件之前手工配置。

ssh和scp创建连接,检验是否存在:

ls -l /usr/local/bin/ssh

ls -l /usr/local/bin/scp

不存在则创建

/bin/ln -s /usr/bin/ssh /usr/local/bin/ssh

/bin/ln -s /usr/bin/scp /usr/local/bin/scp

 

 

另外需要说明的是,配置了ssh后也经常有连接拒绝的情况,多数情况下是由于/etc/ssh/ssh_config/etc/hosts.allow/etc/hosts.deny3个文件的问题。

1、/etc/ssh/ssh_config文件中加入GRID及Oracle用户所在的组:

AllowGroups sysadmin asmdba oinstall

2、修改vi /etc/hosts.deny文件,用#注释掉sshd:ALL,或者加入ssh:ALL EXCEPT 2个节点的公网及2个节点的私网,中间用逗号隔开,如:

ssd : ALL EXCEPT 192.168.59.128,192.168.59.129,10.10.10.5,10.10.10.6

也可以修改:/etc/hosts.allow文件,加入sshd:ALL

sshd:192.168.59.128,192.168.59.129,10.10.10.5,10.10.10.6

2个文件的配置有冲突以/etc/hosts.deny为准。

3、重启ssd服务:/etc/init.d/sshd restart

 

1.5.2.1  方法一:普通配置

分别配置grid和oracle用户的ssh

----------------------------------------------------------------------------------

[oracle@ZFLHRDB1 ~]$ ssh ZFLHRDB1 date

[oracle@ZFLHRDB1 ~]$ ssh ZFLHRDB2 date

[oracle@ZFLHRDB1 ~]$ ssh ZFLHRDB1-priv date

[oracle@ZFLHRDB1 ~]$ ssh ZFLHRDB2-priv date

 

[oracle@ZFLHRDB2 ~]$ ssh ZFLHRDB1 date

[oracle@ZFLHRDB2 ~]$ ssh ZFLHRDB2 date

[oracle@ZFLHRDB2 ~]$ ssh ZFLHRDB1-priv date

[oracle@ZFLHRDB2 ~]$ ssh ZFLHRDB2-priv date

-----------------------------------------------------------------------------------

[oracle@ZFLHRDB1 ~]$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

[oracle@ZFLHRDB1 ~]$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

[oracle@ZFLHRDB1 ~]$ ssh ZFLHRDB2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys  ->输入ZFLHRDB2密码

[oracle@ZFLHRDB1 ~]$ ssh ZFLHRDB2 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys  ->输入ZFLHRDB2密码

[oracle@ZFLHRDB1 ~]$ scp ~/.ssh/authorized_keys ZFLHRDB2:~/.ssh/authorized_keys    ->输入ZFLHRDB2密码

 

 

-----------------------------------------------------------------------------------

测试两节点连通性:

[oracle@ZFLHRDB1 ~]$ ssh ZFLHRDB1 date

[oracle@ZFLHRDB1 ~]$ ssh ZFLHRDB2 date

[oracle@ZFLHRDB1 ~]$ ssh ZFLHRDB1-priv date

[oracle@ZFLHRDB1 ~]$ ssh ZFLHRDB2-priv date

 

[oracle@ZFLHRDB2 ~]$ ssh ZFLHRDB1 date

[oracle@ZFLHRDB2 ~]$ ssh ZFLHRDB2 date

[oracle@ZFLHRDB2 ~]$ ssh ZFLHRDB1-priv date

[oracle@ZFLHRDB2 ~]$ ssh ZFLHRDB2-priv date

 

 

 

第二次执行时不再提示输入口令,并且可以成功执行命令,则表示SSH对等性配置成功

 

1.5.2.2  方法二:用sshUserSetup.sh快速创建互信(推荐方法)

sshUserSetup.sh在GI安装介质解压缩后的sshsetup目录下。下面两条命令在一个节点上执行即可在root用户下执行:

./sshUserSetup.sh -user grid  -hosts "raclhr-12cR1-N2 raclhr-12cR1-N1" -advanced exverify –confirm

./sshUserSetup.sh -user oracle  -hosts "raclhr-12cR1-N2 raclhr-12cR1-N1" -advanced exverify -confirm

输入yes及密码一路回车即可。

1.5.3  cluster  硬件检测--安装前预检查配置信息

Use Cluster Verification Utility (cvu)

Before installing Oracle Clusterware, use CVU to ensure that your cluster is prepared for an installation:

Oracle provides CVU to perform system checks in preparation for an installation, patch updates, or other system changes. In addition, CVU can generate fixup scripts that can change many kernel parameters to at lease the minimum settings required for a successful installation.

Using CVU can help system administrators, storage administrators, and DBA to ensure that everyone has completed the system configuration and preinstallation steps.

./runcluvfy.sh -help

./runcluvfy.sh stage -pre crsinst -n rac1,rac2 –fixup -verbose

Install the operating system package cvuqdisk to both Oracle RAC nodes. Without cvuqdisk, Cluster Verification Utility cannot discover shared disks, and you will receive the error message "Package cvuqdisk not installed" when the Cluster Verification Utility is run (either manually or at the end of the Oracle grid infrastructure installation). Use the cvuqdisk RPM for your hardware architecture (for example, x86_64 or i386). The cvuqdisk RPM can be found on the Oracle grid infrastructure installation media in the rpm directory. For the purpose of this article, the Oracle grid infrastructure media was extracted to the /home/grid/software/oracle/grid directory on racnode1 as the grid user.

 

只需要在其中一个节点上运行即可

 

在安装 GRID 之前,建议先利用 CVU(Cluster Verification Utility)检查 CRS 的安装前环境。以grid用户运行:

export CVUQDISK_GRP=oinstall

./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose

$ORACLE_HOME/bin/cluvfy stage  -pre crsinst -n all  -verbose -fixup

未检测通过的显示为failed,有的failed可以根据提供的脚本进行修复。有的需要根据情况进行修复,有的failed也可以忽略。

[root@raclhr-12cR1-N1 grid]# su - grid

[grid@raclhr-12cR1-N1 ~]$ cd /soft/grid/

[grid@raclhr-12cR1-N1 grid]$ ./runcluvfy.sh stage -pre crsinst -n raclhr-12cR1-N1,raclhr-12cR1-N2 -fixup -verbose

小麦苗的环境有如下3个failed

Check: Total memory

  Node Name     Available                 Required                  Status   

  ------------  ------------------------  ------------------------  ----------

  raclhr-12cr1-n2  1.9518GB (2046592.0KB)    4GB (4194304.0KB)         failed   

  raclhr-12cr1-n1  1.9518GB (2046592.0KB)    4GB (4194304.0KB)         failed   

Result: Total memory check failed

 

Check: Swap space

  Node Name     Available                 Required                  Status   

  ------------  ------------------------  ------------------------  ----------

  raclhr-12cr1-n2  2GB (2097144.0KB)         2.9277GB (3069888.0KB)    failed   

  raclhr-12cr1-n1  2GB (2097144.0KB)         2.9277GB (3069888.0KB)    failed   

Result: Swap space check failed

 

 

Checking integrity of file "/etc/resolv.conf" across nodes

PRVF-5600 : On node "raclhr-12cr1-n2" The following lines in file "/etc/resolv.conf" could not be parsed as they are not in proper format: raclhr-12cr1-n2

PRVF-5600 : On node "raclhr-12cr1-n1" The following lines in file "/etc/resolv.conf" could not be parsed as they are not in proper format: raclhr-12cr1-n1

Check for integrity of file "/etc/resolv.conf" failed

 

都可以忽略。
