MongoDB 副本集在 DESKTOP 而不是 localhost 上启动

Question

我想在 mongoose 中使用事务，因此我在开发阶段安装了 run-rs 来测试它。根据像这样的指南https://medium.com/cashpositive/the-hitchhikers-guide-to-mongodb-transactions-with-mongoose-5bf8a6e22033 run-rs 在本地主机上启动它。当我通过终端运行run-rs -v 4.2.5 --keep --shell 启动副本集时，它显示：在“mongodb://DESKTOP-U9IDO6F:27017,DESKTOP-U9IDO6F:27018,DESKTOP-U9IDO6F:27019?replicaSet=rs”上启动副本集。为什么它为我说 DESKTOP 而不是 localhost，我将如何在 mongoose.connect() 中连接到它？

我在 index.js 中尝试了以下内容：

const app = express();
const PORT = 27017;
const dbUri = 'mongodb://DESKTOP-U9IDO6F:27017,DESKTOP-U9IDO6F:27018,DESKTOP-U9IDO6F:27019?replicaSet=rs'

mongoose.Promise = global.Promise;
mongoose.connect(dbUri, {
    replicaSet: 'rs',
    useNewUrlParser: true,
    useUnifiedTopology: true
});

另外我将如何附加数据库名称？

更新 我接受了下面的答案，因为用于连接的字符串有效，因此解决了原始问题。但是我切换到 Linux，它现在无需进一步设置即可工作。 run-rs 似乎在我的 Windows 机器上不起作用。

替换：

const dbUri = 'mongodb://DESKTOP-U9IDO6F:27017,DESKTOP-U9IDO6F:27018,DESKTOP-U9IDO6F:27019?replicaSet=rs'

与：

const dbUri = 'mongodb://localhost:27017,localhost,localhost:27019/databasenaeme'

还需要在这些端口手动运行 mongoDb。参考链接：
