1. 安装oracle linux 8.4

选择本地可用的ISO 文件（虚拟机安装）

挂载后重启

选择timezone

2. 主机相关配置
设置主机名 永久有效

*Hostnamectl set-hostname xxxxx*
设置IP地址 重启不变

[root@21ctest2 etc]# timedatectl set-timezone Asia/Shanghai

3.配置本地yum源并安装所需的依赖包

挂载本地yum源
打开remote console 挂载iso文件 并重启

启动后可以看到挂载的iso文件

创建挂载点 并将iso挂上去

[root@21ctest2 ~]# mkdir -p /mnt/cdrom/
[root@21ctest2 ~]# mount /dev/sr0 /mnt/cdrom/
mount: /mnt/cdrom: WARNING: device write-protected, mounted read-only.

####fs setting
fs.aio-max-nr = 4194304
fs.file-max = 6815744
####kernel setting
kernel.shmall = 4194304
kernel.shmmax = 16106127360
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
kernel.panic_on_oops = 1
kernel.panic = 10
#### Net Setting
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 = 4194304
##TCP Cache Setting
net.ipv4.tcp_moderate_rcvbuf=1

4.4	创建用户/组和目录
/usr/sbin/groupadd -g 50001 oinstall
/usr/sbin/groupadd -g 50002 dba
/usr/sbin/groupadd -g 50003 oper
/usr/sbin/groupadd -g 50004 backupdba

mkdir -p /u01/app/21.0.0/grid
mkdir -p /u01/app/oracle
mkdir -p /u01/app/oracle/product/21.0.0/db_1
chown -R grid:oinstall /u01
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01

5.虚拟机配置共享磁盘
虚拟机添加共享存储盘两个节点虚拟机都关机
编辑设置

两台节点都添加一个新的scsi控制器，属性如下

节点一添加磁盘

节点二新加磁盘选择现有磁盘，将节点一新加的磁盘选中
Test2新加磁盘为test1 已有的磁盘

完成以上操作后 开机
确保两个节点都能看到新加磁盘

6.配置共享存储

[root@21ctest1 ~]# fdisk /dev/sde
Welcome to fdisk (util-linux 2.32.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

	配置用户环境变量
注意修改实例名
注意grid的ORACLE_BASE不再和oracle下的公用,所以grid的一些trace文件放在grid用户下ORACLE_BASE/diag下面
grid用户:
.bash_profile
export ORACLE_SID=+ASM1
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/21.0.0/grid
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$PATH
export LANG=en_US
oracle用户:
=====================================
export ORACLE_SID=21ctest1
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/21.0.0/db_1
export GRID_HOME=/u01/app/21.0.0/grid
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$GRID_HOME/bin:$PATH
export LANG=en_US
root用户:
=====================================
export ORACLE_HOME=/u01/app/21.0.0/grid
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$PATH
export LANG=en_US

7. 安装21c grid
安装和19c区别不大
