python - pymongo - 无法连接到在 EC2 上运行的 mongodb

Question

我正在连接到 EC2 上的 mongodb 服务器。 mongo 集合需要身份验证才能连接。

我尝试了所有方法，但出现以下错误，并且似乎无法纠正。

from pymongo import MongoClient

mongo_username = "username"
mongo_password = "password"
ssh_user = "user"
ssh_address = "ec2-**********.amazonaws.com"
ssh_port = 22
private_key = "path/to/key/mykey.pem"

def connect_to_mongo():
   try:
        client = MongoClient("mongodb://"+mongo_username+":"+mongo_password+"@" + ssh_address, ssl = True, ssl_keyfile = private_key)
        db = client.myDB

        #Should 'admin' be there or 'myDB'? 'admin' at least get if(auth) passed, while 'myDB' doesn't 
        auth = client.admin.authenticate(mongo_username,mongo_password) 

        if(auth):
                print "MongoDB connection successful"
                col = db.myCollection.count()
        else:
                print "MongoDB authentication failure: Please check the username or password"

        client.close()

   except Exception as e:
        print "MongoDB connection failure: Please check the connection details"
        print e

if __name__ == "__main__":
    connect_to_mongo()

输出:

MongoDB connection successful
MongoDB connection failure: Please check the connection details
SSL handshake failed: EOF occurred in violation of protocol (_ssl.c:590)

EC2默认会关闭27017端口。按照描述创建入站规则 here和 here .
