RAC19详细安装步骤

本文主要是介绍RAC19详细安装步骤,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

CentOS7.6搭建RAC

1.系统环境配置

1.1概述

​ 搭建两个节点的rac集群,其每个节点均有两个网卡,public网卡和private网卡。两个节点的主机名分别为rac1和rac2

1.2 参数设置(RAC1&RAC2)

  • 编辑/etc/hosts文件

    vim /etc/hosts
    

    注释掉以下内容,

    #127.0.0.1   localhost rac1 localhost4 localhost4.localdomain4
    #::1         localhost rac1 localhost6 localhost6.localdomain6
    

    注:如果没有注释上述内容,在安装rac的先决条件检查时,会报PRVG-13632错误。

    追加以下内容

    #RAC-PUBLIC-IP
    192.168.100.101 rac1
    192.168.100.102 rac2
    
    #RAC-PRIVATE-IP
    10.10.10.101 rac1-priv
    10.10.10.102 rac2-priv
    
    #RAC-VIP
    192.168.100.201 rac1-vip
    192.168.100.202 rac2-vip
    
    #RAC-SCAN-IP
    192.168.100.200 rac-scan
    

1.3 关闭防火墙

  • 关闭防火墙服务
systemctl disable firewalld.service
  • selinux配置

    vi /etc/selinux/config
    

    把enforcing更改为disabled

    # 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 three values:
    #     targeted - Targeted processes are protected,
    #     minimum - Modification of targeted policy. Only selected processes are protected.
    #     mls - Multi Level Security protection.
    SELINUXTYPE=targeted
    
  • 挂载系统光盘

  • 配置本地yum源

    mkdir /yums
    cd /run/media/root/CentOS 7 x86_64/Packages
    cp * /yums
    rpm -ivh deltarpm-3.6-3.el7.x86_64.rpm 
    rpm -ivh python-deltarpm-3.6-3.el7.x86_64.rpm 
    rpm -ivh createrepo-0.9.9-28.el7.noarch.rpm
    cd  /yums
    createrepo .
    vi /etc/yum.repos.d/yum.local.repo
    
    [local]
    name=yum local repo
    baseurl=file:///yums
    gpgcheck=0
    enable=1
    
  • 安装 依赖包

  • 关闭透明大页

    cp /etc/default/grub /etc/default/grub.bak
    vi /etc/default/grub
    

    追加一行

    GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet transparent_hugepage=never"

    GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet transparent_hugepage=never"

    GRUB_DISABLE_RECOVERY="true"
    GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet transparent_hugepage=never"
    
  • 内核参数配置

    vi /etc/sysctl.conf
    
    kernel.shmmax = 2126008812
    kernel.shmmni = 4096
    kernel.sem = 250 32000 100 128

    生成系统参数

    sysctl -p 
    

​ 注:

kernel.shmmax

​ 用于定义单个共享内存段的最大值。设置应该足够大,能在一个共享内存段下容纳下整个的 SGA。32 位 linux 系统:可取最大值为 4GB ( 4294967296bytes ) -1byte;64 位 linux 系统:可取的最大值为物理内存值 -1byte.

​ 建议值为多于物理内存的一半,一般取值大于 SGA_MAX_SIZE 即可,可以取物理内存 -1byte

kernel.shmall :

​ 可以使用的共享内存的总页数, Linux 共享内存页大小为 4KB

  • 修改pam.d/login

    vim /etc/pam.d/login

    使udev生效

    udevadm control --reload-rules
    udevadm trigger
    
  • avahi-daemon 配置

    yum install -y avahi*
    systemctl stop avahi-daemon.socket
    systemctl stop avahi-daemon.service
    pgrep -f avahi-daemon | awk '{print "kill -9 "$2}'
    systemctl disable avahi-daemon.socket
    systemctl disable avahi-daemon.service
    cat <<EOF>>/etc/sysconfig/network
    NOZEROCONF=yes
    EOF
    
  • 时间同步配置

    禁用chronyd

    yum install -y chrony
    timedatectl set-timezone Asia/Shanghai
    systemctl stop chronyd.service
    systemctl disable chronyd.service
    

    配置时间同步定时任务

    yum install -y ntpdate
    ##192.168.100.150为时间服务器IP,每天12点同步系统时间
    vim /var/spool/cron/root
    
    00 12 * * * /usr/sbin/ntpdate -u 192.168.100.150 && /usr/sbin/hwclock -w
    
    ##手动执行
    /usr/sbin/ntpdate -u 192.168.100.150 && /usr/sbin/hwclock -w
    

2.RAC安装(RAC1)

2.1节点互信

  • 节点互信

    上传sshUserSetup.sh脚本到/root

    注:这个脚本是Oracle提供的,可以解压Oracle压缩包或者Grid压缩包,查找该脚本上传到rac1即可

    sh sshUserSetup.sh -user root -hosts "rac1 rac2" -advanced -noPromptPassphrase
    sh sshUserSetup.sh -user grid -hosts "rac1 rac2" -advanced -noPromptPassphrase
    sh sshUserSetup.sh -user oracle -hosts "rac1 rac2" -advanced -noPromptPassphrase
    

2.2 Grid安装

  • 上传Grid文件

    把LINUX.X64_193000_grid_home.zip上传到/u01/app/19c/grid

    cd /u01/app/19c/grid
    chown -R grid:oinstall LINUX.X64_193000_grid_home.zip
    
  • 切换grid用户解压

    su - grid
    cd $ORACLE_HOME
    unzip LINUX.X64_193000_grid_home.zip
    

    等待解压完毕

  • 配置DISPLAY变量

    export DISPLAY=192.168.100.103:0.0
    ./gridSetup.sh
    

    注:IP写自己宿主机的IP地址

  • 安装过程



这里的SCAN NAME一定要和你/etc/hosts文件里的那个RAC-SCAN-IP的名称保持一致而不是和IP保持一致。

点击Add




如果密码设置过于简单,会警告密码设置过于简单,点击Yes,继续

是否注册EMCC,不使用,不配置







有两个检查状态是失败的,主要是由于没有使用到DNS服务,所以报错,可以忽略。


点击“Yes”



注:以root用户,按rac1,rac2的顺序先后执行这两个脚本,例如orainstRoot在rac1执行完毕后,然后在rac2执行

[root@rac1 ~]# /u01/app/oraInventory/orainstRoot.sh
Changing permissions of /u01/app/oraInventory.
Adding read,write permissions for group.
Removing read,write,execute permissions for world.

Changing groupname of /u01/app/oraInventory to oinstall.
The execution of the script is complete.
[root@rac1 ~]# /u01/app/19c/grid/root.sh

3.数据库安装(RAC1)

3.1上传安装包

  • 以root用户上传LINUX.X64_193000_db_home.zip到/u01/app/oracle/product/19c/db_1下

  • 更改所属用户,所属组

    [root@rac1 ~]# cd /u01/app/oracle/product/19c/db_1
    [root@rac1 db_1]# chown -R oracle:oinstall LINUX.X64_193000_db_home.zip
    
    

3.2 解压缩

  • 切换用户

    [root@rac1 db_1]# su - oracle
    Last login: Tue Apr 19 09:24:47 CST 2022 on pts/0
    
  • 切换目录

    [oracle@rac1:/home/oracle]$cd $ORACLE_HOME
    [oracle@rac1:/u01/app/oracle/product/19c/db_1]$cd /u01/app/oracle/product/19c/db_1
    
  • 解压

    unzip LINUX.X64_193000_db_home.zip
    

3.3 安装数据库

  • 设置DISPLAY变量

    [oracle@rac1:/u01/app/oracle/product/19c/db_1] export DISPLAY=192.168.100.66:0.0
    
    
  • 运行安装程序

    [oracle@rac1:/u01/app/oracle/product/19c/db_1] ./runInstaller
    

    注:

    1.要投影安装界面的主机(192.168.100.66)的防火墙要关闭,否则会报类似以下错误,

    2.如果使用Xshell连接的服务器或者虚拟机的话,投影的机器或者宿主机要安装xMananger。

    [oracle@rac1:/u01/app/oracle/product/19c/db_1]$./runInstaller
    ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyinfo exist under PATH variable.
    
    Can't connect to X11 window server using '192.168.100.66:0.0' as the value of the DISPLAY variable.
    
  • 安装过程

    注:只安装数据库软件,安装数据库软件成功后,再创建实例。








    主要是DNS的问题, 直接忽略即可。


    点击“Yes”



    分别以root用户在rac1和rac2上运行该脚本

    点击“Close”,安装完成

4.建库(RAC1)

4.1 调取安装界面

切换到grid用户,调取安装界面创建数据库

[root@rac1 ~]# su - grid
Last login: Thu Apr 28 20:19:54 CST 2022
[grid@rac1:/home/grid]$export DISPLAY=192.168.100.66:0.0
[grid@rac1:/home/grid]$asmca

4.2 创建ASM的DG







关闭对话框

4.2 创建数据库

  • 切换到oracle用户并调用安装界面

    [grid@rac1:/home/grid]$su - oracle
    Password:
    Last login: Mon Apr 25 21:42:45 CST 2022
    [oracle@rac1:/home/oracle]$export DISPLAY=192.168.100.66:0.0
    [oracle@rac1:/home/oracle]$dbca
    
  • 创建过程





    注:可以不创建容器数据库,直接创建数据库,也可以根据需求创建容器数据库后,创建可插拔数据库。


    注:根据需求,决定是否开启归档,也可以在创建数据库后,开启归档,这里暂时不开启归档。




    注:选择字符AL32UTF8字符集

    注:根据需求选择是共享服务器模式还是独占服务器模式

直接忽略
