MongoDB 副本集在 DESKTOP 而不是本地主机上启动

Question

我想使用 mongoose 的交易，所以我在开发阶段安装了运行-rs 来测试它。根据这样的指南 https://medium.com/cashpositive/the-hitchhikers-guide-to-mongodb-transactions-with-mongoose-5bf8a6e22033 运行-rs 在本地主机上启动它。当我运行 run-rs -v 4.2.5 --keep --shell 通过终端启动副本集时，它说：在 "mongodb://DESKTOP-U9IDO6F:27017,DESKTOP-U9IDO6F:27018,DESKTOP-U9IDO6F:27019?replicaSet=rs" 上启动副本集。为什么它对我说桌面而不是本地主机，我如何在 mongoose.connect()?

中连接到它

我在 index.js 中尝试了以下方法：

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 并且现在无需进一步设置即可使用。运行-rs 似乎无法在我的 Windows 机器上运行。

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。使用 link 作为参考：

MongoDB replica-set starts on DESKTOP instead of localhost

node.js
