Cloudreve迁移：V2-->V4

https://github.com/cloudreve/Cloudreve

 

 

 

cloudreve 是一款开源的网盘软件，我部署的版本比较老是V2版本，目前官方只有v3--》v4，怎么办：

环境：linux

cloudreve 使用sqlite作为数据库

1 首先下载v4新版本

2 直接运行./cloudreve

    1） 虽然官方说使用  ./cloudreve  migrate --v3-conf conf.ini -c data/conf.ini  命令可以直接将v3 转换为 v4，可是会报错：

[Error] 2025-06-12 20:40:33 [/home/vsts/work/1/s/cmd/migrate.go:62] Failed to migrate: failed to create setting hash_id_salt: SQL logic error: no such table: settings (1)

    2）直接运行之后会产生 cloudreve.db 这个库文件，使用dbeaver连接进去，清理settings groups 等等表，否则会报约束错误：

[Error] 2025-06-12 21:33:13 [/home/vsts/work/1/s/cmd/migrate.go:62] Failed to migrate: failed to create setting hash_id_salt: ent: constraint failed: constraint failed: UNIQUE constraint failed: settings.name (2067)

3 在老库创建表，由于migrate并适用v2 版本，所以有些表迁移的时候会报失败：

[Error] 2025-06-12 21:35:03 [/home/vsts/work/1/s/cmd/migrate.go:62] Failed to migrate: failed to list v3 nodes: SQL logic error: no such table: nodes (1)

4 创建表

```

CREATE TABLE `source_links` (
`id` integer NOT NULL PRIMARY KEY AUTOINCREMENT,
`created_at` datetime,
`updated_at` datetime,
`deleted_at` datetime,
`node_id` integer,
`owner_id` integer
);

 

CREATE TABLE `nodes` (
`id` integer NOT NULL PRIMARY KEY AUTOINCREMENT,
`created_at` datetime,
`updated_at` datetime,
`deleted_at` datetime,
`name` varchar(255),
`source_name` varchar(255),
`parent_id` integer,
`size` bigint,
`type` varchar(255),
`policy_id` integer,
`owner_id` integer
);

```

5 运行迁移命令

# ./cloudreve migrate --v3-conf conf.ini -c data/conf.ini

成功！
