Study--Oracle-03-Oracle19C--RAC集群部署

一、硬件信息及配套软件

1、硬件设置

RAC集群虚拟机：CPU:2C、内存：9G、操作系统：30G、数据库安装目录：100G

数据存储：50G （10G*5）

共享存储：2G （1G*2）

2、IP 划分

3、配套软件

 操作系统：    OracleLinux-R7-U9-Server-x86_64-dvd
 数据库软件：oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm 

数据库集群软件：LINUX.X64_193000_grid_home.zip

关注以下这三个rpm包

compat-libstdc++-33-3.2.3-71.el7.x86_64.rpm

libaio-devel-0.3.109-13.el7.x86_64.rpm

ksh-20120801-144.0.1.el7_9.x86_64.rpm

二、环境配置

1、主机名设置

主机：192.168.87.131
[root@rac1 ~]# hostnamectl set-hostname rac1   

主机：192.168.87.132
[root@rac2 ~]# hostnamectl set-hostname rac2

主机：192.168.87.129
[root@san ~]#  hostnamectl set-hostname san

2、主机名及网络设置

vi /etc/hosts
192.168.87.131 rac1
192.168.87.132 rac2

10.10.10.131   rac1prv
10.10.10.132   rac2prv

192.168.87.133 rac1vip
192.168.87.134 rac2vip

192.168.87.129 san

3、防火墙及SELINUX设置

关闭selinux
sed -i  "s/SELINUX=enforcing/SELINUX=disabled/"  /etc/selinux/config
setenforce 1

关闭防火墙
systemctl  stop firewalld
systemctl  disable firewalld

4、进制NTP时钟服务禁止NTP
systemctl stop ntpd
systemctl disabled ntpd
systemctl stop chronyd.service
systemctl disable chronyd.service
rm -f /etc/chrony.conf

5、安装相关rpm包

yum install bc gcc gcc-c++  binutils  make gdb cmake  glibc ksh \
elfutils-libelf elfutils-libelf-devel fontconfig-devel glibc-devel  \
libaio libaio-devel libXrender libXrender-devel libX11 libXau sysstat \
libXi libXtst libgcc librdmacm-devel libstdc++ libstdc++-devel libxcb \
net-tools nfs-utils compat-libcap1 compat-libstdc++  smartmontools  targetcli \
python python-configshell python-rtslib python-six  unixODBC unixODBC-devel

推荐安装以下命令
yum install -y lrzsz
yum install -y rsync
yum install -y telnet
yum install -y vim
yum install -y curl
yum install -y wget
yum install -y openssh-server
yum install -y openssh-clients
yum install -y lsof

三、部署Oracle--19C --RAC集群

1、rac1/rac2 安装预装软件

[root@rac1 opt]# rpm -ivh oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm 

安装完毕后会自动创建用户和组，不建议使用默认的配置

2、rac1/rac2重新创建oracle相关用户及组

userdel  -r oracle
userdel  -r grid 
groupdel oinstall 
groupdel dba

groupadd -g 5001 oinstall
groupadd -g 5002 dba
groupadd -g 5003 asmdba 
groupadd -g 5004 asmoper
groupadd -g 5005 asmadmin
useradd   -u 6001 -g oinstall -G asmadmin,asmdba,asmoper grid 
useradd   -u 6002 -g oinstall -G dba,asmadmin oracle

passwd oracle
passwd grid 

检查核实用户

3、rac1/rac2创建oracle相关目录并赋权

mkdir /opt/oracle
mkdir -p /opt/oracle/app/grid
mkdir -p /opt/oracle/app/19c/grid
chown -R grid:oinstall /opt/oracle

mkdir -p /opt/oracle/app/oraInventory
chown -R grid:oinstall /opt/oracle/app/oraInventory
mkdir -p /opt/oracle/app/oracle/product/19c/dbhome_1 
chown -R oracle:oinstall /opt/oracle/app/oracle 
chmod -R 775 /opt/oracle

4、rac1/rac2设置grid用户环境变量

 vi ~/.bash_profile 
umask 022

#rac1
export ORACLE_SID=+ASM1

#rac2

export ORACLE_SID=+ASM1
export ORACLE_BASE=/opt/oracle/app/grid
export ORACLE_HOME=/opt/oracle/app/19c/grid 
export PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin

5、rac1/rac2设置oracle用户环境变量

[oracle@rac1 ~]$ vi ~/.bash_profile 

umask 022
export ORACLE_BASE=/opt/oracle/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/19c/dbhome_1
export ORACLE_UNQNAME=rac
export ORACLE_SID=rac1
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin

6、ASM共享存储配置

服务端执行

yum -y install nfs-utils rpcbind

[root@san ~]# vi /etc/exports
/asm *(insecure,rw,no_root_squash,no_all_squash,sync)
[root@san ~]# systemctl restart nfs-server.service
[root@san ~]# 
[root@san ~]# showmount -e
Export list for san:
/asm *
[root@san ~]# exportfs -v
/asm            <world>(sync,wdelay,hide,no_subtree_check,sec=sys,rw,insecure,no_root_squash,no_all_squash)

设置开机自启动

[root@san ~]# systemctl start rpcbind.service
[root@san ~]# systemctl start nfs-server.service
[root@san ~]# systemctl enable rpcbind.service
[root@san ~]# systemctl enable nfs-server.service

客户端配置
[root@rac1 opt]# yum -y install nfs-utils rpcbind
[root@rac1 opt]# mount -t nfs 192.168.87.129:/asm /asm
[root@rac2 opt]# mount -t nfs 192.168.87.129:/asm /asm

检查共享存储权限

[root@san ~]# ls -ld /asm/
drwxrwxrwx 3 777 root 4096 May 19 20:57 /asm/

配置开机启动

vi /etc/fstab 
192.168.87.129:/asm nfs defaults 0 0

Linux使用nfs设置共享文件夹_linux配置nfs共享-CSDN博客

NFS共享存储主机执行
mkdir -p /asm/oracleasm/disks
dd if=/dev/zero of=/asm/oracleasm/disks/asm1 bs=8192k count=1280 
dd if=/dev/zero of=/asm/oracleasm/disks/asm2 bs=8192k count=1280 
dd if=/dev/zero of=/asm/oracleasm/disks/asm3 bs=8192k count=1280 
dd if=/dev/zero of=/asm/oracleasm/disks/asm4 bs=8192k count=1280
dd if=/dev/zero of=/asm/oracleasm/disks/asm5 bs=8192k count=1280 
dd if=/dev/zero of=/asm/oracleasm/disks/asm6 bs=8192k count=128
dd if=/dev/zero of=/asm/oracleasm/disks/asm7 bs=8192k count=128

rac1/rac2 主机执行
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

检查权限设置

 [root@san ~]# chmod -R 777 /asm/

7、安装数据库集群软件-grid
 rac1主机解压 LINUX.X64_193000_grid_home.zip

  [grid@rac1 ~]$ cd $ORACLE_HOME
  [grid@rac1 grid]$ pwd
  /opt/oracle/app/19c/grid

 #需要在页面执行
 [grid@rac1 ~]$ ./gridSetup.sh
