背景
通过 docker compose -f docker-compose.yml -p ragflow up -d 部署了 ragflow本地服务，现在想迁移到另一台服务器上，服务可以通过github 拉取最新的 https://github.com/infiniflow/ragflow 代码，重新配置启动。
但是原服务器上添加过的数据，比如知识库，怎么迁移到新服务器，避免重复添加，重复操作呢？
一、我的配置文件
启动 ragflow 基础配置文件如下 ： docker-compose-base.yml
可以看到，各个基础服务的 volumes 数据卷名称和挂载信息

根据上面提供的 docker-compose-base.yml 配置文件内容，下面是 RAGFlow 各个组件在本地的数据存储路径说明：
✅ 数据存储路径一览（基于你的配置文件）
| 组件 | 容器内路径 | 本地路径（默认） | 用途说明 |
|---|---|---|---|
| MySQL | /var/lib/mysql | mysql_data（默认在 Docker 管理的 volume 中） | 存储用户、文档元数据等结构化信息 |
| MinIO | /data | minio_data（Docker volume） | 存储上传的原始文档、处理后的文本等 |
| Elasticsearch (es01) | /usr/share/elasticsearch/data | esdata01（Docker volume） | 存储关键词搜索索引数据 |
| OpenSearch (opensearch01) | /usr/share/opensearch/data | osdata01（Docker volume） | 可选搜索引擎，用于检索 |
| Infinity（向量数据库） | /var/infinity | infinity_data（Docker volume） | 存储向量索引 |
| Redis | /data | redis_data（Docker volume） | 缓存数据、任务状态等 |
| Sandbox Executor Manager | 无持久化数据 | 无 | 用于运行沙箱任务，不持久化 |
关于这些 volumes 的说明
你在 docker-compose-base.yml 文件末尾定义了如下 volume：
volumes:esdata01:driver: localosdata01:driver: localinfinity_data:driver: localmysql_data:driver: localminio_data:driver: localredis_data:driver: local
这些 volumes 是 Docker 管理的命名卷（named volumes），默认情况下它们会存储在 Docker 的默认数据目录中：
- Linux 系统下通常为：
/var/lib/docker/volumes/<volume_name>/_data
例如：
- MySQL 数据实际路径为：
/var/lib/docker/volumes/mysql_data/_data - MinIO 数据实际路径为：
/var/lib/docker/volumes/minio_data/_data
📁 如何查看这些卷在本地的具体位置？
可能用到的docker 命令如下。
📦 总结建议
| 目标 | 建议 |
|---|---|
| 查看数据存储位置 | 使用 docker volume inspect <volume_name> |
| 备份数据 | 备份对应路径，如 /var/lib/docker/volumes/mysql_data/_data |
| 自定义路径 | 修改 docker-compose-base.yml 中的 volumes 配置 |
| 清理数据 | 删除对应 volume，如 docker volume rm mysql_data |
所以，我们想查看某个 volume 的实际路径，可以有两种方法：
- find / -name ‘esdata01’
- docker volume inspect xxxx
本次我们使用如下命令，esdata01 是从上面配置文件中获悉：
(base) root@hostname:/home/ltkj# docker volume inspect esdata01
[]
Error response from daemon: get esdata01: no such volume(base) root@hostname:/home/ltkj# docker volume inspect ragflow_esdata01
输出示例：
[{"CreatedAt": "2025-06-13T10:52:28Z","Driver": "local","Labels": {"com.docker.compose.config-hash": "3bcef595c5f477c290ccaa07cbf05671d287fef95c1fa4b67fad841e66481794","com.docker.compose.project": "ragflow","com.docker.compose.version": "2.34.0","com.docker.compose.volume": "esdata01"},"Mountpoint": "/var/lib/docker/volumes/ragflow_esdata01/_data","Name": "ragflow_esdata01","Options": null,"Scope": "local"}
]
这样就能知道 esdata01，minio，MySQL 等基础服务的数据存在哪里了。
🛠️ 如果想自定义这些路径
可以在 volumes 配置中指定本地路径，例如：
volumes:mysql_data:driver: localdriver_opts:type: noneo: binddevice: /opt/ragflow/mysql_data
这样 MySQL 数据就会存在 /opt/ragflow/mysql_data。
