[root@rac1 ~]# lsb_release -a LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: OracleServer Description: Oracle Linux Server release 6.5 Release: 6.5 Codename: n/a [root@rac1 ~]# uname -r 3.8.13-16.2.1.el6uek.x86_64

细节说明:
1. 安装Oraclelinux时,注意分配两个网卡,一个网卡为Host Only方式,用于两台虚拟机节点的通讯,另一个网卡为Nat方式,用于连接外网,后面再手动分配静态IP。每台主机的内存和swap规划为至少2.5G。硬盘规划为:boot 500M,其他空间分配为LVM方式管理,LVM划分2.5G为swap,其他为/。
两台Oracle Linux主机名为rac1、rac2
注意这里安装的两个操作系统最好在不同的硬盘中,否则I/O会很吃力。
2. 由于采用的是共享存储ASM,而且搭建集群需要共享空间作注册盘(OCR)和投票盘(votingdisk)。VMware创建共享存储方式:
进入VMware安装目录,cmd命令下:

    这里创建了两个1G的ocr盘,一个1G的投票盘,一个20G的数据盘,一个10G的备份盘。

    这里就在RAC2的虚拟机设置中手动添加创建好的五个虚拟硬盘,要求是独立永久属性

    网络规划

    硬件配置要求:
    - 每个服务器节点至少需要2块网卡,一个对外网络接口,一个私有网路接口(心跳)。
    - 如果你通过OUI安装Oracle集群软件,需要保证每个节点用于外网或私网接口(网卡名)保证一致。比如,node1使用eth0作为对外接口,node2就不能使用eth1作为对外接口。

    IP配置要求:
    这里不采用DHCP方式,指定静态的scan ip(scan ip可以实现集群的负载均衡,由集群软件按情况分配给某一节点)。
    每个节点分配一个ip、一个虚拟ip、一个私有ip。
    其中ip、vip和scan-ip需要在同一个网段。

    非GNS下手动配置IP实例:

    Identity Home Node Host Node Given Name Type Address
    RAC1 Public RAC1 rac1 Public 192.168.248.101
    RAC1 VIP rac1-vip 192.168.248.201
    RAC1 Private rac1-priv Private 192.168.109.101
    RAC2 rac2 192.168.248.102
    RAC2 VIP rac2-vip 192.168.248.202
    RAC2 Private rac2-priv 192.168.109.102
    SCAN IP none Selected by Oracle Clusterware scan-ip virtual 192.168.248.110

    环境配置

    默认情况下,下面操作在每个节点下均要进行,密码均设置oracle

    1. 通过SecureCRT建立命令行连接

    • sqlplus中Backspace出现^H的乱码
      Options->Session Options->Terminal->Emulation->Mapped Keys->Other mappings
      勾选Backspace sends delete

    • vi中不能使用delete和home
      Options->Session Options->Terminal->Emulation
      设置Terminal为Linux
      勾选Select an alternate keyboard emulation为Linux

    2. 关闭防火墙

    3. 创建必要的用户、组和目录,并授权

    参照官方文档,采用GI与DB分开安装和权限的策略,对于多实例管理有利。

    4. 节点配置检查

    内存大小:至少2.5GB
    Swap大小:
    当内存为2.5GB-16GB时,Swap需要大于等于系统内存。
    当内存大于16GB时,Swap等于16GB即可。
    查看内存和swap大小:

      
      
  • 1
  • 2
  • 3
  • 4
    • 1
    • 2
    • 3
    • 4
    [root@rac1 ~]# grep MemTotal /proc/meminfo MemTotal: 2552560 kB [root# grep SwapTotal /proc/meminfo SwapTotal: 2621436 kB

    如果swap太小,swap调整方法

    通过此种方式进行swap 的扩展,首先要计算出block的数目。具体为根据需要扩展的swapfile的大小,以M为单位。block=swap分区大小*1024,例如,需要扩展64M的swapfile,则:block=64*1024=65536.

    然后做如下步骤:

    #dd if=/dev/zero of=/swapfile bs=1024 count=65536
    #mkswap /swapfile
    #swapon /swapfile
    #vi /etc/fstab
    增加/swapf swap swap defaults 0 0
    # cat /proc/swaps 或者# free –m //查看swap分区大小
    # swapoff /swapf //关闭扩展的swap分区

    5. 系统文件设置

    (1)内核参数设置:
    [root@rac1 ~]# vi /etc/sysctl.conf
    kernel.msgmnb = 65536
    kernel.msgmax = 65536
    kernel.shmmax = 68719476736
    kernel.shmall = 4294967296
    fs.aio-max-nr = 1048576
    fs.file-max = 6815744
    kernel.shmall = 2097152
    kernel.shmmax = 1306910720
    kernel.shmmni = 4096
    kernel.sem = 250 32000 100 128
    net.ipv4.ip_local_port_range = 9000 65500
    net.core.rmem_default = 262144
    net.core.rmem_max = 4194304
    net.core.wmem_default = 262144
    net.core.wmem_max = 1048586
    net.ipv4.tcp_wmem = 262144 262144 262144
    net.ipv4.tcp_rmem = 4194304 4194304 4194304

    这里后面检测要改
    kernel.shmmax = 68719476736

    确认修改内核
    [root@rac1 ~]# sysctl -p

    也可以采用Oracle Linux光盘中的相关安装包来调整
    [root@rac1 Packages]# pwd
    /mnt/cdrom/Packages
    [root@rac1 Packages]# ll | grep preinstall
    -rw-r–r– 1 root root 15524 Dec 25 2012 oracle-rdbms-server-11gR2-preinstall-1.0-7.el6.x86_64.rpm

    (2)配置oracle、grid用户的shell限制
    [root@rac1 ~]# vi /etc/security/limits.conf
    grid soft nproc 2047
    grid hard nproc 16384
    grid soft nofile 1024
    grid hard nofile 65536
    oracle soft nproc 2047
    oracle hard nproc 16384
    oracle soft nofile 1024
    oracle hard nofile 65536

    (3)配置login
    [root@rac1 ~]# vi /etc/pam.d/login
    session required pam_limits.so

    1. 安装需要的软件包
      binutils-2.20.51.0.2-5.11.el6 (x86_64)
      compat-libcap1-1.10-1 (x86_64)
      compat-libstdc++-33-3.2.3-69.el6 (x86_64)
      compat-libstdc++-33-3.2.3-69.el6.i686
      gcc-4.4.4-13.el6 (x86_64)
      gcc-c++-4.4.4-13.el6 (x86_64)
      glibc-2.12-1.7.el6 (i686)
      glibc-2.12-1.7.el6 (x86_64)
      glibc-devel-2.12-1.7.el6 (x86_64)
      glibc-devel-2.12-1.7.el6.i686
      ksh
      libgcc-4.4.4-13.el6 (i686)
      libgcc-4.4.4-13.el6 (x86_64)
      libstdc++-4.4.4-13.el6 (x86_64)
      libstdc++-4.4.4-13.el6.i686
      libstdc++-devel-4.4.4-13.el6 (x86_64)
      libstdc++-devel-4.4.4-13.el6.i686
      libaio-0.3.107-10.el6 (x86_64)
      libaio-0.3.107-10.el6.i686
      libaio-devel-0.3.107-10.el6 (x86_64)
      libaio-devel-0.3.107-10.el6.i686
      make-3.81-19.el6
      sysstat-9.0.4-11.el6 (x86_64)

      这里使用的是配置本地源的方式,自己先进行配置:
      [root@rac1 ~]# mount /dev/cdrom /mnt/cdrom/
      [root@rac1 ~]# vi /etc/yum.repos.d/dvd.repo
      [dvd]
      name=dvd
      baseurl=file:///mnt/cdrom
      gpgcheck=0
      enabled=1
      [root@rac1 ~]# yum clean all
      [root@rac1 ~]# yum makecache
      [root@rac1 ~]# yum install gcc gcc-c++ glibc* glibc-devel* ksh libgcc* libstdc++* libstdc++-devel* make sysstat

    6.配置IP和hosts、hostname

    (1)配置ip
    //这里的网关有vmware中网络设置决定,eth0为连接外网,eth0内网心跳
    //rac1主机下:
    [root@rac1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
    IPADDR=192.168.248.101
    PREFIX=24
    GATEWAY=192.168.248.2
    DNS1=114.114.114.114

    [root@rac1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth1
    IPADDR=192.168.109.101
    PREFIX=24

    //rac2主机下
    [root@rac2 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
    IPADDR=192.168.248.102
    PREFIX=24
    GATEWAY=192.168.248.2
    DNS1=114.114.114.114

    [root@rac2 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth1
    IPADDR=192.168.109.102
    PREFIX=24

    (2)配置hostname
    //rac1主机下
    [root@rac1 ~]# vi /etc/sysconfig/network
    NETWORKING=yes
    HOSTNAME=rac1
    GATEWAY=192.168.248.2
    NOZEROCONF=yes

    //rac2主机下
    [root@rac2 ~]# vi /etc/sysconfig/network
    NETWORKING=yes
    HOSTNAME=rac2
    GATEWAY=192.168.248.2
    NOZEROCONF=yes

    (3)配置hosts
    rac1和rac2均要添加
    [root@rac1 ~]# vi /etc/hosts
    192.168.248.101 rac1
    192.168.248.201 rac1-vip
    192.168.109.101 rac1-priv

    192.168.248.102 rac2
    192.168.248.202 rac2-vip
    192.168.109.102 rac2-priv

    192.168.248.110 scan-ip

    7.配置grid和oracle用户环境变量

    Oracle_sid需要根据节点不同进行修改
    [root@rac1 ~]# su - grid
    [grid@rac1 ~]$ vi .bash_profile

    export TMP=/tmp export TMPDIR=$TMP export ORACLE_SID=+ASM1 # RAC1 export ORACLE_SID=+ASM2 # RAC2 export ORACLE_BASE=/u01/app/grid export ORACLE_HOME=/u01/app/11.2.0/grid export PATH=/usr/sbin:$PATH export PATH=$ORACLE_HOME/bin:export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib umask 022

    需要注意的是ORACLE_UNQNAME数据库名,创建数据库时指定多个节点是会创建多个实例,ORACLE_SID指的是数据库实例名

    [root@rac1 ~]# su - oracle
    [oracle@rac1 ~]$ vi .bash_profile

    export ORACLE_SID=orcl1  export ORACLE_SID=orcl2  export ORACLE_UNQNAME=orcl
    export ORACLE_BASE=/u01/app/oracle
    export ORACLE_HOME=$ORACLE_BASE/product/0/db_1
    export TNS_ADMIN=$ORACLE_HOME/network/admin
    $ORACLE_HOME/lib:/lib:/usr/lib

    $ source .bash_profile使配置文件生效

    8.配置oracle用户ssh互信

    这是很关键的一步,虽然官方文档中声称安装GI和RAC的时候OUI会自动配置SSH,但为了在安装之前使用CVU检查各项配置,还是手动配置互信更优。

    需要注意的是生成密钥时不设置密码,授权文件权限为600,同时需要两个节点互相ssh通过一次。

    @L_502_53@9.配置裸盘

    使用asm管理存储需要裸盘,前面配置了共享硬盘到两台主机上。配置裸盘的方式有两种(1)oracleasm添加(2)/etc/udev/rules.d/60-raw.rules配置文件添加(字符方式帮绑定udev) (3)脚本方式添加(块方式绑定udev,速度比字符方式快,最新的方法,推荐用此方式)

    在配置裸盘之前需要先格式化硬盘:

      
      
  • 1
  • 2
  • 3
  • 4
  • 5
  • 6
  • 7
  • 8
  • fdisk /dev/sdb Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (4): 1 最后 w 命令保存更改

    重复步骤,格式化其他盘,得到如下分区
    [root@rac1 ~]# ls /dev/sd*
    /dev/sda /dev/sda2 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1 /dev/sda1 /dev/sdb /dev/sdc /dev/sdd /dev/sde /dev/sdf

    添加裸盘:

    用这种方式添加,在后面的添加asm磁盘组的时候,需要指定Change Diskcovery Path为/dev/*asm*

    10.配置grid用户ssh互信

    11.挂载安装软件文件

    这里是主机windows系统开启文件夹共享,让后虚拟机挂载即可
    mkdir -p /home/grid/db
    mount -t cifs -o username=share,password=123456 //192.168.248.1/DB /home/grid/db

    mkdir -p /home/oracle/db
    mount -t cifs -o username=share,password=123456 //192.168.248.1/DB /home/oracle/db

    12.安装用于Linux的cvuqdisk

    在Oracle RAC两个节点上安装cvuqdisk,否则,集群验证使用程序就无法发现共享磁盘,当运行(手动运行或在Oracle Grid Infrastructure安装结束时自动运行)集群验证使用程序,会报错“Package cvuqdisk not installed”
    注意使用适用于硬件体系结构(x86_64或i386)的cvuqdisk RPM。
    cvuqdisk RPM在grid的安装介质上的rpm目录中。

    13.手动运行cvu使用验证程序验证Oracle集群件要求(所有节点都执行)

    rac1到grid软件目录下执行runcluvfy.sh命令:

      
      
  • 1
  • 2
  • 3
  • 4
  • 5
  • 6
  • [root@rac1 ~]# su - grid [grid@rac1 ~]$ cd db/grid/ [@rac1 grid]$ ls doc readme.html rpm runInstaller stage install response runcluvfy.sh sshsetup welcome.html [grid]$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose

    查看cvu报告,修正错误
    这里CVU执行的所有其他检查的结果为”passed”,只出现了如下错误
    Checking DNS response time for an unreachable node
    Node Name Status


    rac2 Failed
    rac1 Failed
    PRVF-5637 : DNS response time could not be checked on following nodes: rac2,rac1

    File “/etc/resolv.conf” is not consistent across nodes

    这个错误是因为没有配置DNS,但不影响安装,后面也会提示resolv.conf错误,我们用静态的scan-ip,所以可以忽略。

    安装Grid Infrastructure

    1.安装流程

    只需要在一个节点上安装即可,会自动复制到其他节点中,这里在rac1中安装。
    进入图形化界面,在grid用户下进行安装

    grid/
    doc/          readme.html   rpm/          runInstaller  stage/
    install/      response/     runcluvfy.sh  sshsetup/     welcome.html
    [grid]$ ./runInstaller

    跳过更新
    这里写图片描述

    选择安装集群

    选择自定义安装

    选择语言为English

    定义集群名字,SCAN Name 为hosts中定义的scan-ip,取消GNS

    界面只有第一个节点rac1,点击“Add”把第二个节点rac2加上

    选择网卡

    配置ASM,这里选择前面配置的裸盘raw1,raw2,raw3,冗余方式为External即不冗余。因为是不用于,所以也可以只选一个设备。这里的设备是用来做OCR注册盘和votingdisk投票盘的。

    配置ASM实例需要为具有sysasm权限的sys用户,具有sysdba权限的asmsnmp用户设置密码,这里设置统一密码为oracle,会提示密码不符合标准,点击OK即可

    不选择智能管理

    检查ASM实例权限分组情况

    选择grid软件安装路径和base目录

    选择grid安装清单目录

    环境检测出现resolv.conf错误,是因为没有配置DNS,可以忽略

    安装grid概要

    开始安装

    复制安装到其他节点

    安装grid完成,提示需要root用户依次执行脚本orainstRoot.sh ,root.sh (一定要先在rac1执行完脚本后,才能在其他节点执行)

    在rac1中执行脚本

    确认针对Oracle Clusterware文件的Oracle ASM功能
    如果在 Oracle ASM 上暗转过了OCR和表决磁盘文件,则以Grid Infrastructure 安装所有者的身份,使用给下面的命令语法来确认当前正在运行已安装的Oracle ASM:

      
      
  • 1
  • 2
  • 3
  • [grid@rac1 ~]$ srvctl status asm -a ASM is running on rac2,rac1 ASM is enabled.

    3.为数据和快速恢复去创建ASM磁盘组

    官方文档中规定了不同冗余策略下OCR、Voting disk、Database和Recovery所需的大小

    只在节点rac1执行即可
    进入grid用户
    [root@rac1 ~]# su - grid
    利用asmca
    [grid@rac1 ~]$ asmca

    这里看到安装grid时配置的OCR盘已存在

    添加DATA盘,点击create,使用裸盘raw4

    同样创建FRA盘,使用裸盘raw5

    ASM磁盘组情况

    ASM实例

    安装Oracle database软件(RAC)

    只需要在节点rac1上执行即可
    [root@rac1 ~]# su - oracle
    [oracle@rac1 ~]$ cd db/database
    [oracle@rac1 database]$ ./runInstaller

    进入图形化界面,跳过更新

    选择只安装数据库软件

    选择Oracel Real Application Clusters database installation按钮(默认),确保勾选所有的节点

    这里的SSH Connectivity是配置每个节点之间的oracle用户互信,前面已手动配置过,可以不配

    选择语言English

    选择安装企业版软件

    选择安装Oracle软件路径,其中ORACLE_BASE,ORACLE_HOME均选择之前配置好的

    oracle权限授予用户组

    安装前的预检查

    这两个错误前面有说明,忽略

    安装RAC的概要信息

    开始安装,会自动复制到其他节点

    安装完,在每个节点用root用户执行脚本
