<!-- Answer --> 你的报错是因为在 `graph_connection` 表中，`name` 字段有唯一约束（unique constraint），当你用 Docker Compose 启动多个 HugeGraph Server 并都设置了 `PASSWORD=hugegraph@2024`，系统初始化时会尝试插入同名的连接，导致主键或唯一索引冲突（即同名连接已存在）[schema.sql 源码](https://github.com/apache/incubator-hugegraph-toolchain/blob/9696d78e4d0b6e10d4e3382248fd8bda61295a91/hugegraph-hubble/hubble-be/src/main/resources/database/schema.sql)。 **解决建议：** 1. 检查数据库（如 H2 文件或 MySQL）中 `graph_connection` 表，删除重复的 name 记录，或更换新的 name。 2. 启动多个 server 时，确保每个服务的连接 name 唯一，或者避免重复初始化同一个连接。 3. 如果是测试环境，可以直接清空 `graph_connection` 表再重启服务。 4. 如果是生产环境，建议先备份数据库，再做清理。 **补充说明：** - `PASSWORD` 环境变量本身不会直接导致唯一约束冲突，但可能触发服务端重复初始化连接逻辑，从而多次插入同名连接，最终报错。 - 目前没有配置项可以自动跳过重复插入，需靠业务或部署流程保证唯一性。 如需进一步排查，可以贴下 `graph_connection` 表的内容或具体初始化流程。 <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
