|
||
## 1. 迁移命令
|
||
|
||
### SQLite
|
||
|
||
```bash
|
||
# 添加迁移
|
||
dotnet ef migrations add InitialCreate --output-dir Migrations/SQLite
|
||
|
||
# 应用迁移
|
||
dotnet ef database update
|
||
```
|
||
|
||
### PostgreSQL
|
||
|
||
```bash
|
||
# 切换配置后添加迁移
|
||
dotnet ef migrations add InitialCreate --output-dir Migrations/PostgreSQL -- --environment PostgreSQL
|
||
|
||
# 应用迁移
|
||
dotnet ef database update -- --environment PostgreSQL
|
||
```
|

|
||
## 2. 切换步骤
|
||
|
||
### 从 SQLite 切换到 PostgreSQL
|
||
|
||
| 步骤 | 操作 | 说明 |
|
||
|------|------|------|
|
||
| 1 | 修改配置 | `appsettings.json` 中 `Database:Type` 改为 `postgresql` |
|
||
| 2 | 设置连接 | 配置 `Host`, `Port`, `Name`, `User`, `Password` |
|
||
| 3 | 创建数据库 | `CREATE DATABASE wctminer;` |
|
||
| 4 | 应用迁移 | `dotnet ef database update` |
|
||
| 5 | 数据迁移 | 使用工具迁移 SQLite 数据到 PostgreSQL |
|
||

## 3. 配置文件示例
|
||
|
||
### SQLite (默认)
|
||
|
||
```json
|
||
{
|
||
"Database": {
|
||
"Type": "sqlite",
|
||
"Path": "./data/database/wctminer.db"
|
||
}
|
||
}
|
||
```
|
||
|
||
### PostgreSQL
|
||
|
||
```json
|
||
{
|
||
"Database": {
|
||
"Type": "postgresql",
|
||
"Host": "localhost",
|
||
"Port": 5432,
|
||
"Name": "wctminer",
|
||
"User": "wctminer_user",
|
||
"Password": "${DB_PASSWORD}"
|
||
}
|
||
}
|
||
```
|
||
|

||
|
||
## 4. 数据迁移工具
|
||
|
||
推荐使用 [pgloader](https://github.com/dimitri/pgloader) 迁移 SQLite 到 PostgreSQL：
|
||
|
||
```bash
|
||
pgloader ./data/database/wctminer.db postgresql://user:password@localhost:5432/wctminer
|
||
``` |
