前置工作

1. 虚拟机配置(物理机忽略)

##设置虚拟磁盘非独占模式 vmx文件添加如下，物理机忽略

scsi1.sharedBus = "virtual"

disk.locking = "false"

diskLib.dataCacheMaxSize = "0"

diskLib.dataCacheMaxReadAheadSize = "0"

diskLib.dataCacheMinReadAheadSize = "0"

diskLib.dataCachePageSize = "4096"

diskLib.maxUnsyncedWrites = "0"

disk.EnableUUID = "TRUE"

##重新启动如遭遇磁盘启动顺序问题，进入"打开电源时进入固件"BIOS修改启动顺序 (nvme本地盘优先 scsi启动 )

2. 网络

nmcli c

NAME UUID TYPE DEVICE

ens160 87bc0295-d0b3-43e5-89fa-0189ebb6ff6f ethernet ens160

virbr0 eb6a769b-962d-449f-bf60-aecadd63f0d8 bridge virbr0

有线连接 1 51d856d2-9b90-37c5-93aa-239639c5a83e ethernet ens224

##网卡的名称ens160 ens224 请按照实际修改

nmcli c delete "Wired connection 1" ##删除带空格的网卡名字,记住DEVICE名字

nmcli c

##用DEVICE名字新建网卡

nmcli c a type Ethernet con-name ens224 ifname ens224

##node1修改IP

nmcli con mod ens224 ipv4.addresses '192.168.201.41/24'

nmcli con mod ens224 ipv4.method manual

nmcli con mod ens224 connection.autoconnect yes

nmcli con mod ens160 ipv4.addresses '192.168.11.41/24'

nmcli con mod ens160 ipv4.method manual

nmcli con mod ens160 connection.autoconnect yes

nmcli con mod ens160 ipv4.gateway "192.168.11.2"

#增加dns

nmcli connection modify ens160 ipv4.dns 8.8.8.8

#删除dns

nmcli connection modify ens160 -ipv4.dns 114.114.114.114

nmcli c reload

nmcli c up ens224

nmcli c

nmcli c up ens160

##node2修改IP

nmcli con mod ens224 ipv4.addresses '192.168.201.42/24'

nmcli con mod ens224 ipv4.method manual

nmcli con mod ens224 connection.autoconnect yes

nmcli con mod ens160 ipv4.addresses '192.168.11.42/24'

nmcli con mod ens160 ipv4.method manual

nmcli con mod ens160 connection.autoconnect yes

nmcli con mod ens160 ipv4.gateway "192.168.11.2" ipv4.dns "8.8.8.8"

nmcli c reload

nmcli c up ens224

nmcli c

nmcli c up ens160

3. 修改主机名配置rac host文件

hostnamectl set-hostname racnode41 ##41

hostnamectl set-hostname racnode42 ##42

#修改/etc/hosts

echo "

#Public IP（公司内部访问，非外网）

192.168.11.41 racnode41

192.168.11.42 racnode42

#Private IP（用于节点间心跳网络）

192.168.201.41 racnode41-priv

192.168.201.42 racnode42-priv

#Virtual IP（提供客户端访问，漂移）

192.168.11.43 racnode41-vip

192.168.11.44 racnode42-vip

#SCAN IP（提供客户端访问，均衡）

192.168.11.45 racnode-scan

" >> /etc/hosts

## 查看修改结果并验证

cat /etc/hosts

ping racnode41

ping racnode42

systemctl disable chronyd.service

chronyd -q 'server ntp.ntsc.ac.cn iburst' #时间服务器可以自行选择，这里选择国家授时中心时间

chronyd -q 'server ntp1.aliyun.com iburst' #阿里云

配置时间同步计划任务：

##yum install -y ntpdate

##自行修改时间服务器IP，例:每天23点同步系统时间

cat <<EOF>>/var/spool/cron/root

##通过pdb$seed 创建一个pdb(26ai 必须使用多租户架构的 CDB（容器数据库）模式，传统的非 CDB 架构已不再受支持，非 CDB 架构在 21c 被标记为弃用，并在后续版本中被彻底移除 )

根据 Oracle 官方文档和技术社区的实践，在 ASM + OMF 环境下使用 CREATE PLUGGABLE DATABASE 时，不应使用 FILE_NAME_CONVERT 子句。正确做法是让 Oracle 自动管理文件位置。

你可以使用以下命令，直接去掉 FILE_NAME_CONVERT 子句

--设置 DB_CREATE_FILE_DEST 参数：在 CDB 根容器（CDB$ROOT）中执行以下命令，指定新 PDB 数据文件的存放位置。在你的 ASM 环境中，这个位置应该是 ASM 磁盘组路径

ALTER SYSTEM SET DB_CREATE_FILE_DEST = '+DATA' SCOPE=BOTH;

--ASM + OMF 创建PDB时让 Oracle 自动管理文件位置,不需要使用FILE_NAME_CONVERT

CREATE PLUGGABLE DATABASE jean ADMIN USER jean IDENTIFIED BY jean;

alter session set container=jean;

alter pluggable database jean open read write;

alter database open;

select OPEN_MODE from v$database;
