3、修改主机名

hostnamectl set-hostname rac1/rac2

4、在两个节点关闭防火墙

systemctl stop firewalld
systemctl disabled firewalld

5、关闭时间同步ntpd服务

systemctl disable ntpd.service
systemctl stop ntpd.service
mv /etc/ntp.conf etc/ntp.conf.old

6、/etc/security/limits.conf

#ORACLE SETTING
grid soft nproc 16384
grid hard nproc 16384
grid soft nofile 16384
grid hard nofile 65536
grid soft stack 16384
grid hard stack 32768
grid hard memlock 8192000
grid soft memlock 8192000
oracle soft nproc 16384
oracle hard nproc 16384
oracle soft nofile 16384
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 32768
oracle hard memlock 8192000
oracle soft memlock 8192000


ulimit -a

7、vi etc/security/limits.d/20-nproc.conf

* - nproc 16384

8、vi etc/pam.d/login

session required pam_limits.so

9、修改内核参数

vi /etc/sysctl.conf
#ORACLE SETTING
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmmax = 8719476736
kernel.shmall = 2128778
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
kernel.panic_on_oops = 1
vm.nr_hugepages = 2500
sysctl -p

10、关闭透明页

cp etc/default/grub etc/default/grub.bak
vi etc/default/grub
在尾部添加 transparent_hugepage=never
GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet transparent_hugepage=never"
执行命令
grub2-mkconfig -o boot/grub2/grub.cfg
 不重启生效
echo never > /sys/kernel/mm/transparent_hugepage/enabled

11、关闭selinix

vi /etc/selinux/config
SELINIX=disabled
setenforce 0

12、配置 NOZEOCONF

vi etc/sysconfig/network
NOZEROCONF=yes

13、停止avahi-daemon服务

systemctl disable avahi-daemon.socket
systemctl disable avahi-daemon.service
ps -ef|grep avahi-daemon
kill -9 pid avahi-daemon

14、在两个节点创建oracle，grid用户组

groupadd -g 54321 oinstall  
groupadd -g 54322 dba  
groupadd -g 54323 oper  
groupadd -g 54324 backupdba  
groupadd -g 54325 dgdba  
groupadd -g 54326 kmdba  
groupadd -g 54327 asmdba  
groupadd -g 54328 asmoper  
groupadd -g 54329 asmadmin  
groupadd -g 54330 racdba  
useradd -u 54321 -g oinstall -G dba,asmdba,backupdba,dgdba,kmdba,racdba,oper oracle  
useradd -u 54322 -g oinstall -G asmadmin,asmdba,asmoper,dba grid
设置grid、oracle密码
passwd oracle
passwd grid
查看
id oracle
id grid

15、在两个节点创建grid、oracle文件目录

mkdir -p u01/app/19.0/grid
mkdir -p u01/app/grid
mkdir -p /u01/app/oracle
mkdir -p /u01/app/oracle/product/19.0/db_1
chown -R grid:oinstall /u01
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/

16、修改grid、oracle用户环境变量

节点1 grid

su - grid
vi ~/.bash_profile


PS1="[`whoami`@`hostname`:"'$PWD]$'
export PS1
umask 022
export TMP=/tmp
export LANG=en_US
export TMPDIR=$TMP
ORACLE_SID=+ASM1; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
ORACLE_BASE=/u01/app/grid; export ORACLE_BASE
ORACLE_HOME=/u01/app/19.0/grid; export ORACLE_HOME
NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"; export NLS_DATE_FORMAT
PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin; export PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
THREADS_FLAG=native; export THREADS_FLAG
if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
        if [ $SHELL = "/bin/ksh" ]; then
            ulimit -p 16384
              ulimit -n 65536
  else
   ulimit -u 16384 -n 65536
      fi
    umask 022
fi

节点2 grid

su - grid
vi ~/.bash_profile


PS1="[`whoami`@`hostname`:"'$PWD]$'
export PS1
umask 022
export TMP=/tmp
export LANG=en_US
export TMPDIR=$TMP

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
THREADS_FLAG=native; export THREADS_FLAG
if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
        if [ $SHELL = "/bin/ksh" ]; then
            ulimit -p 16384
              ulimit -n 65536
  else
   ulimit -u 16384 -n 65536
      fi
    umask 022
fi

节点1 oracle

su - oracle
vi ~/.bash_profile


PS1="[`whoami`@`hostname`:"'$PWD]$'
export PS1
export TMP=/tmp
export LANG=en_US
export TMPDIR=$TMP
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/19.0/db_1; export ORACLE_HOME
ORACLE_SID=orcl1; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"; export NLS_DATE_FORMAT
NLS_LANG=AMERICAN_AMERICA.ZHS16GBK;export NLS_LANG
PATH=.:$PATH:$HOME/bin:$ORACLE_BASE/product/19.0/db_1/bin:$ORACLE_HOME/bin; export PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
THREADS_FLAG=native; export THREADS_FLAG
if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
        if [ $SHELL = "/bin/ksh" ]; then
            ulimit -p 16384
              ulimit -n 65536
  else
   ulimit -u 16384 -n 65536
      fi
    umask 022
fi

节点2 oracle

su - oracle
vi ~/.bash_profile


PS1="[`whoami`@`hostname`:"'$PWD]$'
export PS1
export TMP=/tmp
export LANG=en_US
export TMPDIR=$TMP
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/19.0/db_1; export ORACLE_HOME
ORACLE_SID=orcl2; export ORACLE_SID

if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
        if [ $SHELL = "/bin/ksh" ]; then
            ulimit -p 16384
              ulimit -n 65536
  else
   ulimit -u 16384 -n 65536
      fi
    umask 022
fi

修改root环境变量

vi ~/.bash_profile
PATH=$PATH:/u01/app/19.0.0/grid/bin:$HOME/bin
export PATH

17、共享存储

编写 udev rules 文件,生成文件内容的脚本如下：

for i in c d e;
do
echo "KERNEL==\"sd?\",SUBSYSTEM==\"block\", PROGRAM==\"/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\",RESULT==\"`/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`\", SYMLINK+=\"asm-disk$i\",OWNER=\"grid\", GROUP=\"asmadmin\",MODE=\"0660\""
done

生成的文件拷贝到 /etc/udev/rules.d/99-oracle-asmdevices.rules中。

重启 udev 设备

/sbin/udevadm trigger --type=devices --action=change

检查 udev 设备

ls -lsa /dev/asm*
ls -lsa /dev/sd*

三、安装GRID

信任关系

cd /oracle/app/12.2/grid/oui/prov/resources/scripts/
./sshUserSetup.sh -user grid -hosts "rac1 rac2" -advanced -exverify -confirm
./sshUserSetup.sh -user oracle -hosts "rac1 rac2" -advanced -exverify -confirm
ssh rac1 date && ssh rac2 date && ssh rac1prv date && ssh rac2prv date

在节点1

su - grid
cd $ORACLE_HOME
unzip /soft/V982068-01.zip
./gridSetup.sh

通过asmca创建oracle数据文件磁盘组

asmca图形化安装实例

四、Oracle DataBase软件安装

su - oracle
cd $ORACLE_HOME umzip /soft/V982063-01.zip
./runInstaller

五、dbca创建实例

dbca图形化安装实例

dbca

安装完成。

查看集群状态
crsctl status res -t
