-每一种存储类型的链接配置范例可以在 `env.example` 文件中找到。链接字符串中的数据库实例是需要你预先在数据库服务器上创建好的，LightRAG 仅负责在数据库实例中创建数据表，不负责创建数据库实例。如果使用 Redis 作为存储，记得给 Redis 配置自动持久化数据规则，否则 Redis 服务重启后数据会丢失。

-Example connection configurations for each storage type can be found in the `env.example` file. The database instance in the connection string needs to be created by you on the database server beforehand. LightRAG is only responsible for creating tables within the database instance, not for creating the database instance itself. If using Redis as storage, remember to configure automatic data persistence rules for Redis, otherwise data will be lost after the Redis service restarts.
