准确的说，是Oracle 23ai Free Developer版，因为企业版目前只在云上（OCI和Azure）和ECC上提供。
方法包括3种，本文介绍第2种：
- Virtual Appliance
- RPM安装
- Docker
RPM安装支持Linux 8和Linux 9。由于官方的Virtualbox用的是8，所以我也使用Linux 8。
首先用Vagrant创建一个Oracle Linux 8的虚机，这个也就几分钟就自动安装成功了。
然后下载Linux 8版本的RPM文件：oracle-database-free-23ai-1.0-1.el8.x86_64.rpm，不到1.4GB。
然后就是安装和配置：
# 安装
dnf install -y oracle-database-free*
# 配置
/etc/init.d/oracle-free-23ai configure
下面是详细过程。
首先是安装，耗时5分多钟：
# time dnf install -y /vagrant/oracle-database-free*

还需要设置环境变量，才能登录数据库。如何设？我抄了VIrtual Appliance（第1种方法）的作业。
export ORACLE_HOME=/opt/oracle/product/23ai/dbhomeFree
export ORACLE_SID=FREE
export PATH=/home/oracle/bin:/home/oracle/LDLIB:/opt/oracle/product/23ai/dbhomeFree/bin:/usr/sbin:/home/oracle/java/jdk-11.0.20/bin:/home/oracle/bin:/home/oracle/sqlcl/bin:/home/oracle/sqldeveloper:/home/oracle/datamodeler:/home/oracle/.local/bin:/home/oracle/bin:/usr/share/Modules/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/home/oracle/sqlcl/bin:/home/oracle/sqldeveloper:/home/oracle/bin
然后数据库就可以登录了：

所以登录数据库要改端口，系统口令为oracle：
-- 登录PDB
sqlplus sys@localhost:1539/FREEPDB1 as sysdba
-- 登录CDB
sqlplus sys@localhost:1539/FREE as sysdba
问题
第一个问题是oracle的根目录没有建立：
[root@ol8-vagrant vagrant]# su - oracle
su: warning: cannot change directory to /home/oracle: No such file or directory
虽然你也可以补建一个，但原因不明：
mkdir /home/oracle
chown oracle:oinstall /home/oracle
第二个问题是第一次配置失败的原因还不清楚。
这2个问题需要再做一次实验看看。
存照留念：
