無法從節點連接到泊塢窗中的mongo副本集

Question

我已經建立了一個docker網絡，其中已經建立了3個mongo容器。

我所做的總結：

1. 創建了一個docker網絡，其中我設置了3個mongo docker容器

2. 為第一個節點打開mongo shell，並為副本集設置配置

3. 嘗試從節點應用連接，失敗

4. 從mongo shell成功連接到copysetSet

下面，我將詳細介紹我嘗試過的內容。

這些是我為docker運行的以下cmd：

docker network create my-mongo-cluster

docker run -d -p 30001:27017 --name mongo1 --net my-mongo-cluster mongo mongod --replSet my-mongo-set

docker run -d -p 30002:27017 --name mongo2 --net my-mongo-cluster mongo mongod --replSet my-mongo-set

docker run -d -p 30003:27017 --name mongo3 --net my-mongo-cluster mongo mongod --replSet my-mongo-set

docker exec -it mongo1 mongo

config = { "_id": "my-mongo-set", "members": [{"_id": 0, "host": "mongo1:27017"},{"_id": 1,"host": "mongo2:27017"},{"_id": 3,"host": "mongo3:27017" }   ]}

rs.initiate(config)

通過MongoDB Compass，我已連接到主節點192.168.1.3:30001，並使用一個集合用戶創建了一個數據庫測試。

從節點，我嘗試以下操作：

const app = require('express')();
const mongoose = require('mongoose');

//set up mongo connect
const uri = 'mongodb://192.168.1.3:30001,192.168.1.3:30002,192.168.1.3:30003/test'
mongoose.connect(uri, {useNewUrlParser: true, replicaSet: 'my-mongo-set'})
  .then(() => console.log("MongoDB Connected"))
  .catch(error => console.log(error));

從中我得到

但是，如果我嘗試從mongo shell進行連接，則可以連接：

mongo "mongodb://192.168.1.3:30001,192.168.1.3:30002,192.168.1.3:30003/test"

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).

The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.

To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

my-mongo-set:PRIMARY>

Answer 1

好的，所以我終於弄清楚我在做什么錯。 也許這會幫助某人：

您可以進入C：\\ Windows \\ System32 \\ drivers \\ etc並放入主機MACHINE_IP mongo1 mongo2 mongo3，或者將配置替換為：

config = { "_id": "my-mongo-set", "members": [{"_id": 0, "host": "MACHINE_IP:30001"},{"_id": 1,"host": "<MACHINE_IP>:30002"},{"_id": 2,"host": "<MACHINE_IP>:30003" }   ]}

mongo也有一些問題，弄清楚哪個是主要的，所以我通過添加MONGODB_REPLICA_SET_MODE和MONGODB_PRIMARY_HOST稍微修改了docker run ：

docker run -d -p 30001:27017 --name mongo1 -e MONGODB_REPLICA_SET_MODE=primary --net my-mongo-cluster mongo mongod --replSet my-mongo-set

docker run -d -p 30002:27017 --name mongo2 -e MONGODB_REPLICA_SET_MODE=secondary -e MONGODB_PRIMARY_HOST=mongo1 --net my-mongo-cluster mongo mongod --replSet my-mongo-set

docker run -d -p 30003:27017 --name mongo3 -e MONGODB_REPLICA_SET_MODE=secondary -e MONGODB_PRIMARY_HOST=mongo1 --net my-mongo-cluster mongo mongod --replSet my-mongo-set
