大家好，我是 JiekeXu,江湖人称“强哥”，荣获 Oracle ACE 称号，墨天轮 MVP，墨天轮年度“墨力之星”，拥有 Oracle 11g OCP/OCM 认证,MySQL 5.7/8.0 OCP 认证以及 PCA、PCTA、OBCA、OGCA、KCP 等众多国产数据库认证证书,今天和大家一起来看看 Oracle 23ai free 版本地化安装指南，欢迎点击最上方蓝字“JiekeXu DBA之路”关注我的微信公众号，然后点击右上方三个点“设为星标”顶，更多干货文章才能第一时间推送，谢谢！

北京时间 2024年 5 月 3 日凌晨， Oracle Database 23ai 正式发布！在过去四年中，Oracle 数据库开发部门一直在努力研发 Oracle 数据库的下一个长期支持版本，重点是 AI 和提高开发人员的工作效率。鉴于此版本数据库中对 AI 的关注，Oracle Database 23c 更名为 Oracle Database 23ai。

Oracle Database 23ai 现已在 Oracle Exadata Cloud@Customer、OCI Exadata 数据库服务和 OCI 基础数据库服务上推出。Azure Oracle数据库服务中也有提供。对于开发人员，Oracle Database 23ai 现在可在 Always Free 自治数据库中使用，也可以在 Autonomous Database 23ai Container Image 和 Oracle Database 23ai Free 中下载。

您现在可以下载和试用 Oracle Database 23ai Free 本地版本：


https://www.oracle.com/database/free/get-started 下载 Oracle Database 23ai rpm 和 VM VirtualBox ova 镜像文件，
 
 
https://www.oracle.com/autonomous-database/free-trial/#free-container-image 下载 Autonomous Database 23ai 容器镜像

安装方式有如下图三种：

1）rpm 包安装方式

自 Oracle 18c 以后的版本，除传统的 zip 包安装方式外，便可以使用 rpm 包安装单机数据库。20 年的时候也写过 rpm 安装 19c 企业版的文章，感兴趣的可以点此查看：Oracle 19c 之 RPM 包安装初体验（一），去年 11 月份的时候，写静默安装文章的时候在文末第四章写了 23c rpm 包安装的方式：Oracle 主流版本不同架构下的静默安装指南。

今天我们在 Oracle Linux 8.7 上通过 rpm 包安装 23ai 版本时，需要卸载之前安装的 23c。

配置数据库

/etc/init.d/oracle-free-23ai configure

相当于 dbca 的过程，当然你也可以通过图形化 dbca，我这里就按照官方推荐通过命令行静默配置监听和实例了，需要输入 SYS, SYSTEM and PDBADMIN 管理员用户的密码，注意不能是弱口令，我这里给了大小写加数字 Oracle23Ai


[root@jiekexu init.d]# /etc/init.d/oracle-free-23ai configure
Specify a password to be used for database accounts. Oracle recommends that the password
entered should be at least 8 characters in length, contain at least 1 uppercase
character, 1 lower case character and 1 digit [0-9]. Note that the same
password will be used for SYS, SYSTEM and PDBADMIN accounts:

开机自启动设置

Oracle 建议您将系统配置为在系统启动时自动启动 Oracle Database Free，并在系统关闭时自动关闭系统。自动关闭数据库可防止不正确的数据库关闭。

要自动启动和关闭侦听器和数据库，请按以下方式运行以下命令


# systemctl daemon-reload
# systemctl enable oracle-free-23ai

使用 Configuration Services 脚本关闭和启动

配置侦听器后，可以运行配置服务脚本来检查数据库和侦听器的状态。


# /etc/init.d/oracle-free-23ai status
Status of the Oracle Free 23ai service:
LISTENER status: RUNNING
Free Database status:   RUNNING
 
 
# systemctl start oracle-free-23ai
# systemctl stop  oracle-free-23ai
# systemctl restart oracle-free-23ai

验证开机自启动是否设置成功

2）Docker 版 oracle 23 ai 安装

docker 安装也非常简单，这里并不需要 Linux8,在一台可以联网的 Linux7 即可完成安装，启动 docker，直接 docker pull 就好了。


Su – docker
systemctl status docker
systemctl start docker
systemctl status docker
docker pull container-registry.oracle.com/database/free:latest 
docker run -d --name jieke23ai -h JiekeXu -p 1521:11521 container-registry.oracle.com/database/free:latest
docker exec -it jieke23ai sqlplus / as sysdba

3）导入 ova 安装

oracle 官方提供了一个已经在虚拟机上安装好了的 Oracle 23 ai,并将其打包成 ova 文件，可直接在官方下载，然后安装 VM VitualBox。完了将下载好的 ova 文件导入到虚拟机中，去年 4 月份也写过相关的文章，感兴趣的可点此链接查看：只需三步快速体验 Oracle 23c FREE 开发版，这里就不介绍了。ova 文件自带了 Oracle Linux 8.9+ oracle 23ai free （Oracle Database 23ai Free Release 23.0.0.0.0 – Develop, Learn, and Run for Free Version 23.4.0.24.05）。

在 2022 年 9 月份的时候， Oracle 23c 的一些新特性就广为人知了，当时我也转载过一篇《Oracle Database 23c 十小新特性速览》，今年 5 月发布的 23 ai 涵盖了 300+ 的新特性，一下子全部掌握了还是比较困难的，需要细嚼慢咽。比如，sqlplus 中就有五六个新特性：
