使用Golang和Robo3T连接到MongoDB ReplicaSet时出现问题

Question

我正在努力连接到我的MongoDB副本集，但似乎没有任何工作。

我部署了具有 3 个节点的副本集，每个节点位于单独的 AWS 可用区上，但位于同一区域。

以下是我用于连接到副本集的代码。

    mongoURL := "mongodb://myuser:password@<publicIP>:27017,<publicIP>:27017,<publicIP>:27017/?replicaSet=replica01&authSource=admin"

    clientOptions := options.Client().ApplyURI(mongoURL)

    clientOptions = clientOptions.SetMaxPoolSize(100) //100 is default driver setting

    log.Println("Connection String: " + clientOptions.GetURI())

    client, err := mongo.Connect(ctx, clientOptions)

我还创建了DNS映射并使用它，但这也不起作用。

以下是连接网址

mongodb://adminuser:[e-mail]:27017,rs2.domain.com:27017,rs3.domain.com:27017/?replicaSet=replica01&authSource=admin

机器人3T

当我尝试使用公共IP将副本集与Robo3T连接时，我收到以下错误

无法连接到副本集“IP-RS”[公共 IP：27017]。集合的主数据库无法访问。

原因：集合的任何成员都不可访问。原因：连接失败

当我使用子域名连接到副本集时，我收到以下错误

无法连接到副本集“SRV 副本”[rs1.domain.com:27017]。集合的主数据库无法访问。

原因： 无法初始化 MongoWorker。原因：连接失败

Answer 1

这是解决方案。问题是主机名。我在配置副本集时使用了主机名。这是我的配置$ config = {&nbsp; _id : "mongo-cluster",&nbsp; &nbsp;members : [&nbsp; &nbsp; &nbsp; &nbsp;{_id : 0, host : "mongo-1:27017"},&nbsp; &nbsp; &nbsp; &nbsp;{_id : 1, host : "mongo-2:27017"},&nbsp; &nbsp; &nbsp; &nbsp;{_id : 2, host : "mongo-3:27017"},&nbsp; &nbsp;]}$ rs.initiate(config)溶液我用private-ip更改了。请注意，由于我的 3 个副本节点位于同一 AWS 区域但位于不同的可用区中，因此我使用私有 IP 在节点之间建立连接。hostname$ config = {&nbsp; _id : "replica01",&nbsp; &nbsp;members : [&nbsp; &nbsp; &nbsp; &nbsp;{_id : 0, host : "private-ip:27017"},&nbsp; &nbsp; &nbsp; &nbsp;{_id : 1, host : "private-ip:27017"},&nbsp; &nbsp; &nbsp; &nbsp;{_id : 2, host : "private-ip:27017"},&nbsp;
