环境说明操作系统: Oracle Linux 8 (x86-64)Database: Oracle AI Database 26ai -Single InstanceInstall Type: Software Only建库方式：DBCA创建CDB和PDB
一、安装操作系统
二、环境配置
1、配置本地yum源
[root@26aidb01 etc]# cd /etc [root@26aidb01 etc]# mv yum.repos.d/ yum.repos.d_bak [root@26aidb01 etc]# mkdir yum.repos.d [root@26aidb01 etc]# vi yum.repos.d/local.repo [local] name=Local Repository baseurl=file:///mnt/BaseOS enabled=1 gpgcheck=0 [local-AppStream] name=Local Repository baseurl=file:///mnt/AppStream enabled=1 gpgcheck=0 [root@26aidb01 etc]# mount /dev/cdrom /mnt
2、安装oracle-database-preinstall包
[root@26aidb01 etc]# yum install -y oracle-database-preinstall* Last metadata expiration check: 0:05:14 ago on Thu 29 Jan 2026 01:23:29 AM EST.

以root用户执行上面界面中的2个脚本
脚本执行完成。
软件成功安装。
说明：26aicdb是关键字不能做为CDB的名称
CDB名称更换为cdbxf

3、使用netca创建监听
检查监听状态
