Oracle 19c RAC Linux 7.9 Install

最新学习Oracle 19c RAC的知识，照着Oracle Base等文档过了一下安装过程，留个记录。

一、先决条件--主机配置--两台主机都操作

1、设置主机名和映射--双网卡，生成唯一id：linux 命令uuidgen 需要公有网卡和私用网卡各一块

vi /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.137.31 rac1

192.168.222.180 rac1-priv

192.168.137.33 rac1-vip

192.168.137.32 rac2

192.168.222.181 rac2-priv

192.168.137.34 rac2-vip

192.168.137.35 rac-scan

hostnamectl set-hostname rac1

hostnamectl --static set-hostname rac1

hostnamectl set-hostname rac2

hostnamectl --static set-hostname rac2

more /etc/hostname

[root@rac1 network-scripts]# ifconfig

2、新建账号和组

/usr/sbin/groupadd -g 54321 oinstall

/usr/sbin/groupadd -g 54322 dba

/usr/sbin/groupadd -g 54323 oper

/usr/sbin/groupadd -g 54324 backupdba

/usr/sbin/groupadd -g 54325 dgdba

/usr/sbin/groupadd -g 54326 kmdba

/usr/sbin/groupadd -g 54327 asmdba

/usr/sbin/groupadd -g 54328 asmoper

/usr/sbin/groupadd -g 54329 asmadmin

/usr/sbin/groupadd -g 54330 racdba

/usr/sbin/useradd -u 54321 -g oinstall -G dba,asmdba,oper oracle

/usr/sbin/useradd -u 54322 -g oinstall -G dba,oper,backupdba,dgdba,kmdba,asmdba,asmoper,asmadmin,racdba grid

echo "oracle" | passwd --stdin oracle

echo "grid" | passwd --stdin grid

3、关闭防火墙和selinux

防火墙：

[root@rac1 ~]# systemctl stop firewalld.service

[root@rac1 ~]# systemctl disable firewalld.service

Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.

Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

[root@rac1 ~]#

关闭SELINUX：

[root@rac1 ~]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config

[root@rac1 ~]# cat /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 three values:

# targeted - Targeted processes are protected,

# minimum - Modification of targeted policy. Only selected processes are protected.

# mls - Multi Level Security protection.

SELINUXTYPE=targeted

4、关闭禁用透明大页--Oracle Linux 默认已经关闭了THP，可以不用再进行关闭

[root@localhost network-scripts]# cat /sys/kernel/mm/transparent_hugepage/enabled

[always] madvise never

Linux 7.4 中关闭透明大页：https://www.cndba.cn/dave/article/2673

Linux 7.x 中 Oracle hugepage 大页配置脚本：https://www.cndba.cn/dave/article/2672

5、关闭时钟同步

[root@rac1 ~]# systemctl stop chronyd

[root@rac1 ~]# systemctl disable chronyd

Removed symlink /etc/systemd/system/multi-user.target.wants/chronyd.service.

[root@rac1 ~]#

移除chrony配置文件：（必须移除，否则校验NTP失败）

[root@rac1 software]# mv /etc/chrony.conf /etc/chrony.conf.bak

6、关闭avahi-daemon

[root@rac1 ~]# systemctl stop avahi-daemon

Warning: Stopping avahi-daemon.service, but it can still be activated by:

avahi-daemon.socket

[root@rac1 ~]# systemctl disable avahi-daemon

Removed symlink /etc/systemd/system/multi-user.target.wants/avahi-daemon.service.

Removed symlink /etc/systemd/system/sockets.target.wants/avahi-daemon.socket.

Removed symlink /etc/systemd/system/dbus-org.freedesktop.Avahi.service.

[root@rac1 ~]#

7、创建目录

mkdir -p /u01/app/19.3.0/grid

mkdir -p /u01/app/grid

mkdir -p /u01/app/oracle/product/19.3.0/db_1

chown -R grid:oinstall /u01

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

chmod -R 775 /u01/

设置环境变量

cat /home/oracle/.bash_profile

ORACLE_SID=cndba1;export ORACLE_SID

ORACLE_UNQNAME=cndba;export ORACLE_UNQNAME

JAVA_HOME=/usr/local/java; export JAVA_HOME

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE

ORACLE_HOME=$ORACLE_BASE/product/19.3.0/db_1; export ORACLE_HOME

PATH=.:${JAVA_HOME}/bin:${PATH}:$HOME/bin:$ORACLE_HOME/bin:$ORA_CRS_HOME/bin

PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin

export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib

LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib

LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib

export LD_LIBRARY_PATH

CLASSPATH=$ORACLE_HOME/JRE

CLASSPATH=${CLASSPATH}:$ORACLE_HOME/jlib

CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib

CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib

export CLASSPATH

THREADS_FLAG=native; export THREADS_FLAG

export TEMP=/tmp

export TMPDIR=/tmp

umask 022

cat /home/grid/.bash_profile

PATH=$PATH:$HOME/bin

export ORACLE_SID=+ASM1

export ORACLE_BASE=/u01/app/grid

export ORACLE_HOME=/u01/app/19.3.0/grid

export PATH=$ORACLE_HOME/bin:$PATH:/usr/local/bin/:.

export TEMP=/tmp

export TMP=/tmp

export TMPDIR=/tmp

umask 022

export PATH

8、修改资源限制：/etc/security/limits.d/oracle-database-server-12cR2-preinstall.conf or /etc/security/limits.conf

[root@rac1 ~]# cat >> /etc/security/limits.conf <<EOF

grid soft nproc 2047

grid hard nproc 16384

grid soft nofile 1024

grid hard nofile 65536

grid soft stack 10240

grid hard stack 32768

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

oracle soft stack 10240

oracle hard stack 32768

oracle soft memlock 3145728

oracle hard memlock 3145728

EOF

9、设置 PAM和NOZEROCONF

[root@rac1 ~]# cat >> /etc/pam.d/login <<EOF

session required pam_limits.so

EOF

vi /etc/sysconfig/network增加以下内容

NOZEROCONF=yes

也可以直接执行如下语法完成修改：

echo "NOZEROCONF=yes" >>/etc/sysconfig/network

10、修改内核参数:/etc/sysctl.d/sysctl.conf or /etc/sysctl.d/98-oracle.conf

[root@rac1 ~]# cat >> /etc/sysctl.d/sysctl.conf <<EOF

fs.file-max = 6815744

kernel.sem = 250 32000 100 128

kernel.shmmni = 4096

kernel.shmall = 1073741824

kernel.shmmax = 4398046511104

kernel.panic_on_oops = 1

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

net.ipv4.conf.all.rp_filter = 2

net.ipv4.conf.default.rp_filter = 2

fs.aio-max-nr = 1048576

net.ipv4.ip_local_port_range = 9000 65500

EOF

[root@rac1 ~]# sysctl -p

[root@rac1 ~]/sbin/sysctl -p /etc/sysctl.d/98-oracle.conf

11、安装必须要的包

【[root@rac1 yum.repos.d]# yum clean all

[root@rac1 yum.repos.d]#

[root@rac1 yum.repos.d]# mount /dev/cdrom /mnt

[root@rac1 yum.repos.d]# yum install binutils compat-libstdc++-33 gcc gcc-c++ glibc glibc.i686 glibc-devel ksh libgcc.i686 libstdc++-devel libaio libaio.i686 libaio-devel libaio-devel.i686 libXext libXext.i686 libXtst libXtst.i686 libX11 libX11.i686 libXau libXau.i686 libxcb libxcb.i686 libXi libXi.i686 make sysstat unixODBC unixODBC-devel zlib-devel zlib-devel.i686 compat-libcap1 -y

[root@rac1 software]#】

一、VM共享存储

硬盘配制如下：

/dev/sda 本地磁盘 80G

/dev/ocr_vote01 共享磁盘存放ocr文件 15G

/dev/asm_data01 共享磁盘，用asm管理，存储oracle数据库文件 40G

VMWARE虚拟机创建共享磁盘

1.创建共享磁盘

在虚拟机软件的安装目录下，有个vmware-vdiskmanager.exe文件（老版本用plainmaker.exe），把它复制到共享磁盘柜目录下，创建共享磁盘（老版本共享磁盘文件的扩展名为.pln）

D:\Study\database\Oracle new\Oracle19cRAC\sharewm>vmware-vdiskmanager.exe -c -s 40Gb -a lsilogic -t 2 sharedisk.vmdk

D:\Study\database\Oracle new\Oracle19cRAC\sharewm>vmware-vdiskmanager.exe -c -s 15Gb -a lsilogic -t 2 ahareorc.vmdk

创建完毕后，目录下有六个新文件

sharedisk-flat.vmdk

sharedisk.vmdk

ahareorc-flat.vmdk

ahareorc.vmdk

2.把磁盘加载到虚拟机中

在虚拟机器界面选择“Edit virtual machine settings”

添加硬盘，选“Use a existing virtual disk”，分别添加sharedisk.vmdk、ahareorc.vmdk

双击新加的磁盘，在弹出的磁盘属性窗选“advance”，

为新加的硬盘选择虚拟设备节点：

sharedisk.vmdk选定“SCSI 2:1”。如图所示：

分别打开两台虚拟机目录中的vmx文件，在最后一行添加：

disk.locking = "false"

diskLib.dataCacheMaxSize = "0"

scsi1:1.fileName = "D:\Study\database\Oracle new\Oracle19cRAC\sharewm\sharedisk.vmdk"

scsi1:1.present = "TRUE"

scsi2:1.fileName = "D:\Study\database\Oracle new\Oracle19cRAC\sharewm\ahareorc.vmdk"

scsi2:1.present = "TRUE"

scsi1:1.SharedBus="Virtual"

scsi2:1.SharedBus="Virtual"

disk.EnableUUID ="TRUE"

其中/dev/sdb 对应 quoocr.vmdk,

/dev/sdc 对应 quovote.vmdk,

/dev/sdd 对应 sharedisk.vmdk

3.把ocr，vote作为裸设备，做映射

在rac1上

1>分区

fdisk -l

fdisk /dev/sdd -->/dev/sdd1

disk /dev/sde -->/dev/sde1

2>同步节点信息

/usr/lib/udev/scsi_id -g -u -d /dev/sdd1

/usr/lib/udev/scsi_id -g -u -d /dev/sde1

3>使用udev配置Asm磁盘

[root@rac2 ~]# vi asm.sh //编辑脚本

#!/bin/bash

for i in d e;

echo "KERNEL==\"sd*\",ENV{DEVTYPE}==\"disk\",SUBSYSTEM==\"block\",PROGRAM==\"/usr/lib/udev/scsi_id -g -u -d \$devnode\",RESULT==\"`/usr/lib/udev/scsi_id -g -u /dev/sd$i`\", RUN+=\"/bin/sh -c 'mknod /dev/asmdisk$i b \$major \$minor; chown grid:asmadmin /dev/asmdisk$i; chmod 0660 /dev/asmdisk$i'\""

done

[root@rac1 ~]# ./asm.sh //运行脚本

KERNEL=="sd*",ENV{DEVTYPE}=="disk",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",RESULT=="36000c29956af3b75a5628174e0a7470c", RUN+="/bin/sh -c 'mknod /dev/asmdiskd b $major $minor; chown grid:asmadmin /dev/asmdiskd; chmod 0660 /dev/asmdiskd'"

KERNEL=="sd*",ENV{DEVTYPE}=="disk",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",RESULT=="36000c29171c9477925dbb6a38aff3fcf", RUN+="/bin/sh -c 'mknod /dev/asmdiske b $major $minor; chown grid:asmadmin /dev/asmdiske; chmod 0660 /dev/asmdiske'"

[root@rac1 ~]# vi /etc/udev/rules.d/99-oracle-asmdevices.rules //把上面的脚本内容复制到这个规则

[root@rac1 ~]# udevadm control --reload //udevadm配置重载生效

[root@rac1 ~]# udevadm trigger

[root@rac1 ~]# ll /dev/asm* //查看宿主和组用户，这里必须要先创建用户和组之后才会显示正确

brw-rw----. 1 grid asmadmin 8, 48 May 4 01:11 /dev/asmdiskd

brw-rw----. 1 grid asmadmin 8, 48 May 4 01:11 /dev/asmdiske

12、重启 reboot

三、上传介质，开始安装：

1、上传解压介质

[root@localhost opt]# ll

total 5809664

-rwxr-xr-x. 1 root root 323 May 4 01:09 asm.sh

-rw-r--r--. 1 root root 195388 Mar 14 2015 compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm

-rw-r--r--. 1 root root 3059705302 May 4 01:31 LINUX.X64_193000_db_home.zip

-rw-r--r--. 1 root root 2889184573 May 4 01:30 LINUX.X64_193000_grid_home.zip

从Oracle 12cR2开始，软件直接解压缩到GRID_HOME 或者ORACLE_HOME,而不是在安装时复制过去。该操作只需要在节点1上完成解压缩即可。

我们这里是安装GRID，用grid用户来解压缩GI：

[grid@rac1 software]# unzip -d /u01/app/19.3.0/grid LINUX.X64_193000_grid_home.zip

2、安装cvuqdisk 两个节点都安装

[root@localhost opt]# cd /u01/app/19.3.0/grid/cv/rpm

[root@localhost rpm]#

[root@localhost rpm]# ll

total 12

-rw-r--r--. 1 oracle oinstall 11412 Mar 13 2019 cvuqdisk-1.0.10-1.rpm

[root@localhost rpm]# rpm -ivh cvuqdisk-1.0.10-1.rpm

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

[root@localhost rpm]#

3、运行安装脚本gridSetup.sh

在节点1，进入grid集群软件目录执行GI安装。

[root@localhost rpm]# chown -R grid:oinstall /u01/app/19.3.0/grid

[root@localhost rpm]# su - grid

[grid@rac1 ~]$ cd /u01/app/19.3.0/grid

四、上传介质，安装数据库

4 安装DB

与grid操作相同，用oracle 用户解压缩到ORACLE_HOME。该操作只需要在节点1上完成解压缩即可。

DISPLAY=<machine-name>:0.0; export DISPLAY

# Unzip software.

cd $ORACLE_HOME

unzip -oq /path/to/software/LINUX.X64_193000_db_home.zip

# Interactive mode.

./runInstaller

As a root user, execute the following script(s):

1. /u01/app/oraInventory/orainstRoot.sh

2. /u01/app/oracle/product/19.0.0/dbhome_1/root.sh
