我无法在 mongodb compass 中连接副本集数据库？只有在使用直接连接时才有效

Question

我正在尝试将我的副本集与 MongoDB 指南针连接，因为我的应用程序字符串不起作用..

我有 3 个 mongodb 实例

  },

}

我可以通过studio 3T连接

我可以在环境变量中使用 mongodb://localhost:30001/?directConnection=true 来连接应用程序吗？直接连接安全吗？

这里的问题是我想查看所有 3 个节点..但是直接连接只允许一个主机..如何解决这个问题？

您应该使用此连接字符串进行连接：

mongodb://mongo1:27017,mongo2:27017,mongo3:27017/?replicaSet=mongoSet

见连接字符串 URI 格式
