# OpenIM V2 至 V3 数据迁移指南
|
|
|
|
该指南提供了从 OpenIM V2 迁移至 V3 的详细步骤。请确保在开始迁移过程之前，熟悉所有步骤，并按照指南准确执行。
|
|
|
|
+ [OpenIM Chat](https://github.com/OpenIMSDK/chat)
|
|
+ [OpenIM Server](https://github.com/OpenIMSDK/Open-IM-Server)
|
|
|
|
|
|
|
|
### 1. 数据备份
|
|
|
|
在开始数据迁移之前，强烈建议备份所有相关的数据以防止任何可能的数据丢失。
|
|
|
|
### 2. 迁移 OpenIM MySQL 数据
|
|
|
|
+ 位置: `open-im-server/tools/data-conversion/openim/cmd/conversion-mysql.go`
|
|
+ 配置 `conversion-mysql.go` 文件中的数据库信息。
|
|
+ 手动创建 V3 版本的数据库，并确保字符集为 `utf8mb4`。
|
|
|
|
```bash
|
|
// V2 数据库配置
|
|
var (
|
|
usernameV2 = "root"
|
|
passwordV2 = "openIM"
|
|
addrV2 = "127.0.0.1:13306"
|
|
databaseV2 = "openIM_v2"
|
|
)
|
|
|
|
// V3 数据库配置
|
|
var (
|
|
usernameV3 = "root"
|
|
passwordV3 = "openIM123"
|
|
addrV3 = "127.0.0.1:13306"
|
|
databaseV3 = "openIM_v3"
|
|
)
|
|
```
|
|
|
|
**执行数据迁移命令：**
|
|
|
|
```bash
|
|
make build BINS="conversion-mysql"
|
|
```
|
|
|
|
启动的二进制在 `_output/bin/tools` 中
|
|
|
|
|
|
### 3. 转换聊天消息（可选）
|
|
|
|
+ 只支持转换存储在 Kafka 中的消息。
|
|
+ 位置: `open-im-server/tools/data-conversion/openim/conversion-msg/conversion-msg.go`
|
|
+ 配置 `msg.go` 文件中的消息和服务器信息。
|
|
|
|
```bash
|
|
var (
|
|
topic = "ws2ms_chat" // V2 版本 Kafka 主题
|
|
kafkaAddr = "127.0.0.1:9092" // V2 版本 Kafka 地址
|
|
rpcAddr = "127.0.0.1:10130" // V3 版本 RPC 地址
|
|
adminUserID = "openIM123456" // V3 版本管理员用户ID
|
|
concurrency = 4 // 并发数量
|
|
)
|
|
```
|
|
|
|
**执行数据迁移命令：**
|
|
|
|
```bash
|
|
make build BINS="conversion-msg"
|
|
```
|
|
|
|
### 4. 转换业务服务器数据
|
|
|
|
+ 只支持转换存储在 Kafka 中的消息。
|
|
+ 位置: `open-im-server/tools/data-conversion/chat/cmd/conversion-chat/chat.go`
|
|
+ 需要手动创建 V3 版本的数据库，并确保字符集为 `utf8mb4`。
|
|
+ 配置 `main.go` 文件中的数据库信息。
|
|
|
|
```bash
|
|
// V2 数据库配置
|
|
var (
|
|
usernameV2 = "root"
|
|
passwordV2 = "openIM"
|
|
addrV2 = "127.0.0.1:13306"
|
|
databaseV2 = "admin_chat"
|
|
)
|
|
|
|
// V3 数据库配置
|
|
var (
|
|
usernameV3 = "root"
|
|
passwordV3 = "openIM123"
|
|
addrV3 = "127.0.0.1:13306"
|
|
databaseV3 = "openim_enterprise"
|
|
)
|
|
```
|
|
|
|
**执行数据迁移命令：**
|
|
|
|
```bash
|
|
make build BINS="conversion-chat"
|
|
```
