Python MongoDB副本集-获取错误“；提供了nodename或servname，或未知；连接时

MongoDB V3.6.15

我正在尝试设置一个主副本集、一个辅助副本集和一个仲裁副本集。连接到副本集时获取错误。 pymongo.errors.ServerSelectionTimeoutError:rep2:27017:[Errno 8]提供了或未知的节点名或服务名，rep1:27017:[Errno 8]提供了或未知的节点名或服务名，rep0:27017: [Errno 8]提供了nodename或servname，或未知“

请在下面找到rs.config（）的结果

{ “_id”：“XXXXXXXXX”， “版本”：3， “协议版本”：编号长（1）， “成员”：[ { “_id”：0， “主机”：“rep0:27017”， “任意”：错误， “buildIndexes”：正确， “隐藏”：假， "优先":一,， “标签”：{

}

我在配置副本集时出错了什么

提前谢谢

用于连接到数据库的代码

import os
import pymongo
import ssl
import urllib
MONGODB_URL="mongodb://user:"+urllib.quote("password")+"@rep0xxxxxxxxxx:27017,rep1xxxxxxxxxx:27017,rep2xxxxxxxxxx:27017/admin?ssl=false&replicaSet=replicaname"
client = pymongo.MongoClient(
    MONGODB_URL
)
db = client.get_default_database()
print (db.collection_names())

---

您可以发布用于连接的代码吗？@JoeDrumgoole是的，当然……我已经更新了帖子中的代码。您可以ping列为副本集成员的节点吗？您可以连接mongo shell吗？@JoeDrumgoole我无法从主计算机ping辅助计算机……但是，我可以从主计算机连接到辅助计算机mongo shelly、 我缺少什么？发布ping命令和mongoshell命令输出

import os
import pymongo
import ssl
import urllib
MONGODB_URL="mongodb://user:"+urllib.quote("password")+"@rep0xxxxxxxxxx:27017,rep1xxxxxxxxxx:27017,rep2xxxxxxxxxx:27017/admin?ssl=false&replicaSet=replicaname"
client = pymongo.MongoClient(
    MONGODB_URL
)
db = client.get_default_database()
print (db.collection_names())

Steps

1. Create 3 VMs on Azure Cloud in a same resource group

2. Install MongoDB 3.6.15 on all the Machines

3. Add User on the 3 machines.
db.createUser(
  {
    user: "xxxxxxxxx",
    pwd: "xxxxxxxxx",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" }, "readWriteAnyDatabase" ]
  }
);
db.createUser(
  {
    user: "xxxxxxxxx",
    pwd: "xxxxxxxxx",
    roles: [ { role: "clusterAdmin", db: "admin" }, "readWriteAnyDatabase" ]
  }
);

4. Generate a Key using OpenSSL
openssl rand -base64 756 > /home/rep0/repkey
chmod 400 /home/rep2/repkey
sudo chown mongodb:mongodb /home/rep0/repkey

5. Edit /etc/mongod.conf to enable authentication
security:
  authorization: enabled
  keyFile: /home/rep0/repkey

6. Restart the 3 machines

7. Edit /etc/mongod.conf to add replica set config
replication:
  replSetName: myReplica
  enableMajorityReadConcern: false

8. Restart the 3 machines

9. Add the hosts on all the VM's
Private-IP-Address rep0
Private-IP-Address rep1
Private-IP-Address rep2

10. Open MongoShell for primary machine (one of the 3)

11. execute the command to start replica set and add secondaries.
rs.initiate();
rs.add();
rs.add("host":"rep1");
rs.addArb("rep2");

12. import sample data on the primary machine and confirm the same is replicated on the secondary machines
