• Oracle 12C RAC环境搭建


    -- 检查是否又数据库在运行的命令
    ps -ef|grep smon

    2020-07-02
    1. 操作系统: Oracle Linux 7.6 x86_64
    2. 数据库: 12c
    3.数据库实例名称:
    4.字符集:ZHS16GBK
    5.数据块大小:8k
    6.IP地址:自少会有7个
    7.每台机器要2块网卡

    先把linux环境安装好
    做三个系统,目录下需要挂载好磁盘空间

    1. 文件分区做好, 先每个月预留20个G
    文件做好
    2. 配置IP ,计算机名称,域控等, 保证内网可以访问, 并关闭防火墙设定
    保证xshell可以访问
    TYPE=Ethernet
    PROXY_METHOD=none
    BROWSER_ONLY=no
    BOOTPROTO=static
    DEFROUTE=yes
    IPV4_FAILURE_FATAL=no
    IPV6INIT=yes
    IPV6_AUTOCONF=yes
    IPV6_DEFROUTE=yes
    IPV6_FAILURE_FATAL=no
    IPV6_ADDR_GEN_MODE=stable-privacy
    NAME=ens33
    UUID=ac52ae68-be92-4586-8479-b92425db4107
    DEVICE=ens33
    IPADDR=192.168.32.131
    NETMASK=255.255.255.0
    GATEWAY=192.168.32.2
    ONBOOT=yes
    NM_CONTROLLED=no
    IPV6_PRIVACY=no

    3. 关闭防火墙
    systemctl stop firewalld.service
    systemctl disable firewalld.service

    查看防火墙状态
    systemctl status firewalld

    NAT 网络模式,对应网卡是ens33
    需要修改
    vi /etc/sysconfig/network-scripts/ifcfg-ens33

    重启网络服务
    systemctl restart network

    3.系统名称
    vi /etc/hosts
    192.168.32.131 ocp2

    vi /etc/resolv.conf
    nameserver 8.8.8.8
    -- 最后安装会报错,现在修改为
    namerserver 192.168.32.140
    namerserver 192.168.32.141

    结论是这部分, 在最后都不需要

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

    4. 安装Oracle
    配置 hosts
    相互直接用IP跟名称可以访问 ,A,B 同时配置
    vi /etc/hosts
    192.168.32.140 CQRAC01-EN
    192.168.32.141 CQRAC02-EN

    192.168.30.144 CQRAC01prv -- 不要跟对外一个网段
    192.168.30.145 CQRAC02prv

    192.168.32.146 CQRAC01vip
    192.168.32.147 CQRAC02vip

    192.168.32.100 CQRACscan

    5.关闭SELINIX,防火墙
    echo "SELINUX=disabled" > /etc/selinux/config
    echo "#SELINUXTYPE=targeted" >> /etc/selinux/config
    setenforce 1
    systemctl stop firewalld.service
    systemctl disable firewalld.service

    6. 禁止NTP 时间同步服务
    systemctl stop ntpd
    systemctl disabled ntpd
    systemctl stop chronyd.service
    systemctl disable chronyd.service
    rm -f /etc/chrony.conf

    7.配置 yum 源配置
    mkdir /mnt/linux
    mount /dev/cdrom /mnt/linux
    cd /etc/yum.repos.d
    mkdir bk
    mv *.repo bk/
    echo "[EL]" >> /etc/yum.repos.d/itpux.repo
    echo "name=Linux 7.x DVD" >> /etc/yum.repos.d/itpux.repo
    echo "baseurl=file:///mnt/linux" >> /etc/yum.repos.d/itpux.repo
    echo "gpgcheck=0" >> /etc/yum.repos.d/itpux.repo
    echo "enabled=1" >> /etc/yum.repos.d/itpux.repo

    cat /etc/yum.repos.d/itpux.repo


    8.oracle预备安装前的包
    cd /mnt/hgfs/soft/
    rpm -ivh
    9.权限分配
    S
    /usr/sbin/groupadd -g 60001 oinstall
    /usr/sbin/groupadd -g 60002 dba
    /usr/sbin/groupadd -g 60003 oper
    /usr/sbin/groupadd -g 60004 backupdba
    /usr/sbin/groupadd -g 60005 dgdba
    /usr/sbin/groupadd -g 60006 kmdba

    /usr/sbin/groupadd -g 60007 asmdba
    /usr/sbin/groupadd -g 60008 asmoper
    /usr/sbin/groupadd -g 60009 asmadmin
    /usr/sbin/useradd -u 61001 -g oinstall -G asmadmin,asmdba,dba,asmoper grid
    /usr/sbin/useradd -u 61002 -g oinstall -G dba,backupdba,dgdba,kmdba,asmadmin oracle

    passwd grid
    passwd oracle


    --------------
    10. 处理文件夹

    mkdir -p /u01/app/grid
    mkdir -p /u01/app/12c/grid
    chown -R grid:oinstall /u01

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

    mkdir -p /u01/app/oracle/product/12c/dbhome_1
    chown -R oracle:oinstall /u01/app/oracle
    chmod -R 775 /u01


    11.-----------
    -- 修改配置文件
    vi /etc/sysctl.conf

    fs.aio-max-nr = 1048576
    fs.file-max = 6815744
    kernel.shmmax = 68719476736
    kernel.shmall = 4294967296
    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

    # 配置生效
    sysctl -p

    ------------
    12. 环境变量的配置
    su - grid
    vi ~/.bash_profile
    umask 022
    export ORACLE_SID=+ASM1
    export ORACLE_BASE=/u01/app/grid
    export ORACLE_HOME=/u01/app/12c/grid
    export PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin

    source ~/.bash_profile

    env |grep ORACLE

    --------------------------------------------------------------------
    su - grid
    vi ~/.bash_profile
    umask 022
    export ORACLE_SID=+ASM2
    export ORACLE_BASE=/u01/app/grid
    export ORACLE_HOME=/u01/app/12c/grid
    export PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin

    source ~/.bash_profile

    env |grep ORACLE

    ------------------------------------------------------------------
    su - oracle
    vi ~/.bash_profile
    umask 022
    export ORACLE_BASE=/u01/app/oracle
    export ORACLE_HOME=$ORACLE_BASE/product/12c/dbhome_1
    export ORACLE_UNQNAME=lfscq
    export ORACLE _SID=ifscq1
    export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
    export PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin


    source ~/.bash_profile
    env |grep ORACLE

    ---------------------------------------------------------------------
    su - oracle
    vi ~/.bash_profile
    umask 022
    export ORACLE_BASE=/u01/app/oracle
    export ORACLE_HOME=$ORACLE_BASE/product/12c/dbhome_1
    export ORACLE_UNQNAME=lfscq
    export ORACLE _SID=ifscq2
    export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
    export PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin


    source ~/.bash_profile
    env |grep ORACLE


    13. 配置共享存储
    rm -rf asm
    -- 这是删除目录的命令,不要经常用,避免删除不应该删除的东西

    IP: 192.168.32.142
    配置ASM目录
    vi /etc/exports
    /data *(rw,sync,no_wdelay,insecure,no_root_squash)

    systemctl restart nfs-server.service


    showmount -t
    exportfs -v

    14. 关闭共享存储配置的
    echo "SELINUX=disabled" > /etc/selinux/config
    echo "#SELINUXTYPE=targeted" >> /etc/selinux/config

    cat /etc/selinux/config

    systemctl stop firewalld.service
    systemctl disable firewalld.service

    15. RAC主机配置
    mkdir /asm
    vi /etc/fstab
    192.168.32.142:/data /asm nfs rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0


    mount -a
    chown -R grid:asmadmin /asm


    15. ASM共享磁盘创建
    mkdir -p /data/oracleasm/disks
    dd if=/dev/zero of=/data/oracleasm/disks/asm1 bs=8192k count=1280
    dd if=/dev/zero of=/data/oracleasm/disks/asm2 bs=8192k count=1280
    dd if=/dev/zero of=/data/oracleasm/disks/asm3 bs=8192k count=1280
    dd if=/dev/zero of=/data/oracleasm/disks/asm4 bs=8192k count=1280
    dd if=/dev/zero of=/data/oracleasm/disks/asm5 bs=8192k count=1280
    dd if=/dev/zero of=/data/oracleasm/disks/asm6 bs=8192k count=1280
    dd if=/dev/zero of=/data/oracleasm/disks/asm7 bs=8192k count=1280
    dd if=/dev/zero of=/data/oracleasm/disks/asm8 bs=8192k count=1280
    chown grid:asmadmin /data/oracleasm/disks/asm1
    chown grid:asmadmin /data/oracleasm/disks/asm2
    chown grid:asmadmin /data/oracleasm/disks/asm3
    chown grid:asmadmin /data/oracleasm/disks/asm4
    chown grid:asmadmin /data/oracleasm/disks/asm5
    chown grid:asmadmin /data/oracleasm/disks/asm6
    chown grid:asmadmin /data/oracleasm/disks/asm7
    chown grid:asmadmin /data/oracleasm/disks/asm8

    -- 这个授权有个问题, 就是, 是否是, RAC主机授权这个路径,还是,在共享磁盘组里面,创建grid账号组,再授权。。。
    chown grid:asmadmin /asm/oracleasm/disks/asm1
    chown grid:asmadmin /asm/oracleasm/disks/asm2
    chown grid:asmadmin /asm/oracleasm/disks/asm3
    chown grid:asmadmin /asm/oracleasm/disks/asm4
    chown grid:asmadmin /asm/oracleasm/disks/asm5
    chown grid:asmadmin /asm/oracleasm/disks/asm6
    chown grid:asmadmin /asm/oracleasm/disks/asm7
    chown grid:asmadmin /asm/oracleasm/disks/asm8

    16. 安装grid , 先把软件压缩包拷贝到/mnt中
    用grid 用户解压文件到
    su - grid
    cd $ORACLE_HOME
    unzip linuxx64_12201_grid_home.zip

    su - root
    rpm -Uvh /u01/app/12c/grid/cv/rpm/cvuqdisk*

    17. 执行grid 安装
    grid账户登录虚拟机
    cd $ORACLE_HOME
    ./gridSetup.sh


    18. 需要两块网卡
    cp ifcfg-ens33 ifcfg-ens37

    为网卡生成新的编码
    命令: uuidgen ens37


    UUID
    5958e51e-233c-47f7-a864-df41a9cb160e

    df38ce14-8968-47d1-99b6-defaa0018849

    vi /etc/sysconfig/network-scripts/ifcfg-ens37


    systemctl restart network

    19. 安装grid
    注意事项: 如果服务器重启,那么记得需要先把共享存储挂起来。
    oracle

    安装失败后,最好把路径的软件都删除,重新做
    rm -rf 路径/*

    一定要保证grid安装完成后,才能去安装Oracle ,否则, 更麻烦

    cat /etc/resolv.conf

    CQRAC01-EN 192.168.32.140
    CQRAN02-EN 192.168.32.141
    CQRAC01prv 192.168.30.144
    CQRAC02prv 192.168.30.145
    CQRAC01vip 192.168.32.146
    CQRAC02vip 192.168.32.147
    CQRACscan 192.168.32.100

    CQRACcluster
    CQRACscan

    CQRAC01-EN
    CQRAC01vip

    CQRAC02-EN
    CQRAC02vip

    mv /etc/resolv.conf /etc/resolv.conf.20180620.bak
    这个文件中不能配置, 否则会报错

    20,虚拟机内存要大于最小限制的8个G

    temp 空间不足

    mkdir /u01/tmp
    chown root:root /u01/tmp
    chmod 1777 /u01/tmp


    vi ~/.bash_profile
    export TEMP=/u01/tmp
    export TMPDIR=/u01/tmp

    source ~/.bash_profile

    env |grep TMP

    21. 不光盘挂载一下,看看需要的包
    su - root
    mount /dev/sr0 /mnt
    cd /mnt
    cd Packages/
    ls compat*


    rpm -ivh compat-libcap1-1.10-7.el7.x86_64.rpm
    rpm -ivh libstdc++-devel-4.8.5-16.el7.x86_64.rpm
    rpm -ivh ksh-20120801-34.el7.x86_64.rpm
    rpm -ivh glibc-devel-2.17-196.el7.x86_64.rpm
    rpm -ivh libaio-devel-0.3.109-13.el7.x86_64.rpm
    rpm -ivh glibc-headers-2.17-196.el7.x86_64.rpm
    rpm -ivh kernel-headers-2.6.18-274.el5.x86_64.rpm

    如果发现有些包安装不上, 那是因为有依赖包要先安装, 如果光盘里面没有,那么请到网上下载,并上传到服务器,安装后,再做


    22,检查grid集群运行状态

    出现的错误:
