Oracle 19c RAC installation on centos7.5

1. Node磁盘组规划

规划3个ASM磁盘组，每个磁盘组包含一至多块磁盘，其中/dev/sda为系统盘，ASM磁盘规划如下：
磁盘组名称   磁盘名称   磁盘大小   ASM磁盘名称   作用   冗余
OCR   /dev/sdb   10G   asm-ocr1   OCR/Voting File       EXTERNAL
DATA   /dev/sdc   40G   asm-data1   Data Files                   EXTERNAL
FRA   /dev/sdd   20G      asm-fra1      Fast Recovery area   EXTERNAL

磁盘组说明：

OCR：OCR和表决盘（OCR/Voting File）
DATA：数据盘（Data Files）
FRA：归档和快速恢复区（Fast Recovery area）

文件中末尾加入以下内容后，才可以正常打开虚拟机：


disk.locking = "false"
scsi1.shareBus = "VIRTUAL"
disk.EnableUUID = "TRUE"

配置主机名


# node1
hostnamectl set-hostname node1
 
# node2
hostnamectl set-hostname node2

配置/etc/hosts


[oracle@node1 ~]$ cat /etc/hosts

配置时间同步

使用chrony从公网同步时间（由于拥有CTSS进行时间同步，此步骤无需操作）


yum install -y chrony
systemctl enable --now chronyd

由于有Oracle Cluster Time Synchronization Service (CTSS)同步时间，需要将 NTP和chronyd都禁言。


rm -rf /var/run/chronyd.pid
rm -rf /etc/chrony.conf
rm -rf /etc/ntp.conf
systemctl stop ntpd.service
systemctl disable ntpd
systemctl stop chronyd.service
systemctl disable chronyd.service
 
 
 
----------------------------------------------
 
 
# 检查集群是否存在第三方时间同步服务
cluvfy comp clocksync -n all
 
# 检查ctss的状态
[grid@node1 ~]$ crsctl check ctss
CRS-4700: The Cluster Time Synchronization Service is in Observer mode
 
# 删除第三方时间同步配置文件
 
rm -rf /etc/ntp.conf
rm -rf /etc/chrony.conf
rm -rf /var/run/chronyd.pid
 
# 过大概半分钟 就可以看到状态变成了active模式
 
[grid@node1 ~]$ crsctl check ctss
CRS-4701: The Cluster Time Synchronization Service is in Active mode.
CRS-4702: Offset (in msec): 0
 
# 再次检查集群时间同步
 
[grid@node1 ~]$ cluvfy comp clocksync -n all

配置selinux及防火墙

关闭selinux


 getenforce  ##先检查是否是“Disabled”，如果不是，执行下列操作
 
sed -i 's/=enforcing/=disabled/' /etc/selinux/config  ##如果enforcing是permissive也需要修改成disabled
 
重启OS后执行getenforce查看时候是“Disabled”

关闭firewalld防火墙

systemctl disable --now firewalld

[root@node1 ~]#
[root@node1 ~]# systemctl disable --now firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

节点免密配置

节点node1配置：


su - grid
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
ssh-copy-id node2
 
su - oracle
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
ssh-copy-id node2

节点node2配置：


su - grid
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
ssh-copy-id node1
 
su - oracle
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa

配置/etc/sysconfig/network-scripts目录下的网卡配置文件，加上下面参数。

两台机配好IP并重启网络服务后，将自动绑定划分的两块网卡。

开始安装GRID

在第一个节点node1执行。

使用ssh登陆到grid用户，将下载好的安装包LINUX.X64_193000_grid_home.zip上传到$GRID_HOME目录。

解压到$ORACLE_HOME目录下

[grid@node1 ~]$ unzip LINUX.X64_193000_grid_home.zip -d $ORACLE_HOME

将cvuqdisk rpm包复制到集群上的每个节点

scp $ORACLE_HOME/cv/rpm/cvuqdisk-1.0.10-1.rpm root@node2:/tmp

切换回root用户安装cvuqdisk rpm包。


# node1
CVUQDISK_GRP=oinstall; export CVUQDISK_GRP
rpm -iv /u01/app/19.3.0/grid/cv/rpm/cvuqdisk-1.0.10-1.rpm
 
# node2
CVUQDISK_GRP=oinstall; export CVUQDISK_GRP
rpm -iv /tmp/cvuqdisk-1.0.10-1.rpm

由于使用最小安装的操作系统，若是无图形界面，则需要在node1节点安装xorg-x11（其实此包系统已经存在），并在windows中安装xming以调用GUI界面：


yum install -y xorg-x11-xinit
 
# 重新登录会话生效
exit

安装windows 版本的Xming

Xming X Server for Windows download | SourceForge.net

SecureCRT 中勾选如图所示：

windows中下载安装Xming Server，直接启动即可，SecureCRT将转发图形界面到Xming Server显示。

node1节点以grid用户身份登陆，转到ORACLE_HOME目录

[grid@racdb1:/home/grid]$ cd $ORACLE_HOME

在node1命令行界面执行以下命令开始安装grid

./gridSetup.sh

开始安装ORACLE

SSH登陆到oracle用户，将下载的 zip 文件解压到ORACLE_HOME目录。

[oracle@node1 ~]$ unzip LINUX.X64_193000_db_home.zip -d $ORACLE_HOME

转到ORACLE_HOME目录

cd $ORACLE_HOME

然后运行runInstaller

./runInstaller

注意提示，对于RAC，先安装软件，再运行DBCA创建数据库：

开始安装数据库

ssh连接到oracle用户，验证 DBCA 的要求

/u01/app/19.3.0/grid/bin/cluvfy stage -pre dbcfg -fixup -n node1,node2 -d /u01/app/oracle/product/19.3.0/dbhome_1 -verbose
