我正在努力連接到我的MongoDB副本集，但似乎沒有任何工作。我部署了具有 3 個節點的副本集，每個節點位于單獨的 AWS 可用區上，但位于同一區域。以下是我用于連接到副本集的代碼。 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)我還創建了DNS映射并使用它，但這也不起作用。以下是連接網址mongodb://adminuser:[email protected]:27017,rs2.domain.com:27017,rs3.domain.com:27017/?replicaSet=replica01&authSource=admin機器人3T當我嘗試使用公共IP將副本集與Robo3T連接時，我收到以下錯誤無法連接到副本集“IP-RS”[公共 IP：27017]。集合的主數據庫無法訪問。原因：集合的任何成員都不可訪問。原因：連接失敗當我使用子域名連接到副本集時，我收到以下錯誤無法連接到副本集“SRV 副本”[rs1.domain.com:27017]。集合的主數據庫無法訪問。原因： 無法初始化 MongoWorker。原因：連接失敗

這是解決方案。
問題是主機名。我在配置副本集時使用了主機名。
這是我的配置
$ config = {
_id : "mongo-cluster",
members : [
{_id : 0, host : "mongo-1:27017"},
{_id : 1, host : "mongo-2:27017"},
{_id : 2, host : "mongo-3:27017"},
]
}
$ rs.initiate(config)
溶液
我用private-ip更改了。
請注意，由于我的 3 個副本節點位于同一 AWS 區域但位于不同的可用區中，因此我使用私有 IP 在節點之間建立連接。hostname
$ config = {
_id : "replica01",
members : [
{_id : 0, host : "private-ip:27017"},
{_id : 1, host : "private-ip:27017"},
{_id : 2, host : "private-ip:27017"},
]
}
rs0:PRIMARY> rs.reconfig(config)
所有 3 個節點上的 MongoDB conf 設置
File: /etc/mongod.conf
net:
port: 27017
bindIp: 127.0.0.1, 172.16.1.x (private-ip)
security:
keyFile: /opt/mongo/mongo-keyfile
replication:
replSetName: replica01
所有 3 個節點上的主機
File: /etc/hosts
172.16.1.x mongo-1
172.16.1.x mongo-2
172.16.1.x mongo-3
每臺計算機的名稱應與 /etc/hosts 文件中定義的名稱匹配
$ sudo nano /etc/hostname
mongo-1
