部署Superset BI（三）连接HANA数据库

news 来源：原创 2025/5/7 8:00:29

metabase和redash都不支持HANA数据库，选择superset就是看重这一点，开始尝试连接HANA数据库。
按Superset的技术文档：pip install hdbcli sqlalchemy-hana or pip install apache-superset[hana]

--进入容器
root@Nocobase:/usr/superset/superset# docker exec -it superset_app bash

--安装驱动
root@00aa0c6b0a25:/app# pip install hdbcli sqlalchemy-hana

WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager, possibly rendering your system unusable.It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv. Use the --root-user-action option if you know what you are doing and want to suppress this warning.

但新建数据连接的地方，没有显示SAP HANA的选项。

--创建配置文件
root@Nocobase:/usr/superset/superset/docker#touch requirements-local.txt

root@Nocobase:/usr/superset/superset/docker# echo "hdbcli">> requirements-local.txt
root@Nocobase:/usr/superset/superset/docker# echo "sqlalchemy-hana">> requirements-local.txt

--重启

root@Nocobase:/usr/superset/superset/docker#docker compose down
重启后，可以看到启动初始化已经加载SAP HANA的驱动。

--配置HANA数据库连接

遇连接字符串 haha://username:password@ip:30015
遇到错误，是防火墙问题，配置hana端的防火墙策略，ok.
