Docker 安装非常简单，几乎一分钟内即可完成安装。
Docker 安装 MySQL 9.1
安装镜像：
docker pull container-registry.oracle.com/mysql/community-server:9.1
启动镜像：
docker run --name=mysql91 --restart on-failure -d container-registry.oracle.com/mysql/community-server:9.1
查看初始安装时 root 账号密码：
docker logs mysql91 2>&1 | grep GENERATED
登录安装的数据库：
docker exec -it mysql91 mysql -uroot -p
好了。这就完成安装了：
# docker exec -it mysql91 mysql -uroot -p
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
Enter password:

详细的步骤与说明可以参考：Basic Steps for MySQL Server Deployment with Docker。
其他的 Docker 相关管理命令
docker start mysql91 # 启动
docker stop mysql91 # 关闭
docker restart mysql91 # 重启
docker rm mysql91 # 删除容器
体验 MySQL 9.0/9.1 系列
创建数据库：
mysql> create database orczhou;
Query OK, 1 row affected (0.00 sec)
mysql> use orczhou
Database changed
创建一个表，可以用于存储向量，并进行简单的向量计算：
create table vector_t01 (
id int,
s_v_01 vector(390),
s_v_02 vector(390)
);
mysql> create table vector_t01(id int,s_v_01 vector(390),s_v_02 vector(390));
Query OK, 0 rows affected (0.02 sec)
mysql> insert into vector_t01 values (1,string_to_vector('[1,2,3]'),string_to_vector('[4,5,6]'));
Query OK, 1 row affected (0.00 sec)
mysql> select DISTANCE(s_v_01,s_v_02);
ERROR 1305 (42000): FUNCTION orczhou.DISTANCE does not exist
啥！FUNCTION DISTANCE does not exist
看看文档描述，我下巴掉了一地（参考）：
Note
DISTANCE() is available only for users of HeatWave MySQL on OCI; it is not included in MySQL Commercial or Community distributions.
没有search就算了，好不容易有一个 DISTANCE，发现还是受限制的…
好了，那就体验到这里吧… 期待在后续的版本能够把搜索功能补齐。一定要体验的话，可以自己去Oracle Cloud进行测试。
