编程Tag： 安装 install grid oracle 步骤 yum 22 rac1 RAC19

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

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"

net.ipv4.conf.default.rp_filter = 2

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

vim /etc/pam.d/login

session required /lib/security/pam_limits.so
session required pam_limits.so

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

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

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
