# 私有化配置 (/zh-CN/realtime-media/rtm/build/network-and-private-deployment/private-setup)

自 2.2.0 版本起，RTM 全面支持私有化部署能力。这意味着用户可以自行部署和管理他们的 RTM 环境，从而更好地控制他们的数据和系统。我们致力于为用户提供更灵活、安全和可定制化的解决方案，希望通过这一功能的推出，能够满足更多用户的需求。

RTM 提供两种不同的服务类型，即 `MESSAGE` 服务和 `STREAM` 服务，详见[服务类型](/zh-CN/realtime-media/rtm/build/rtm-initialization/application-setup#servicetype)。具体的服务类型选择取决于你的实际需求和预算，你可以选择部署其中一种或同时部署两种。以下代码展示同时部署了两种服务的私有化环境配置：

```javascript
const appId = "your_appId";
const userId = "your_userId";
const rtmConfig = {
    privateConfig: {
        serviceType: ["MESSAGE", "STREAM"],                                 // 私有化部署的服务类型
        accessPointHosts: ["private.chinanet.com"],        // 私有化部署服务器列表，仅支持填入域名
        domainMode: 2,                                     // 升级已有私有化配置时设置为 2，新部署场景可省略或设为 1
    }
};
const rtm = new RTM(appId, userId, rtmConfig);
```

:::warning[注意]
如果你需要升级私有化部署的 RTM WEB SDK 至 2.2.4 及以后版本，为保证兼容性，需要将 `domainMode` 设置为 `2`。如果省略该参数或使用默认值 `1`，可能无法连接到 RTM 服务器。

:::warning[注意]
如需进行私有化环境部署，你需要先确保后端服务的支持。如果你有此项需求，请联系声网 RTM 团队（rtm-support@agora.io），我们将协助你完成环境配置工作。
