连接远程MongoDB的方式

背景:

在远程阿里云ECS服务器中有个MongoDB数据库:

  • IP:47.96.131.109
  • Port:32018

其中有个:

  • gridfs数据库
    • 用户名:gridfs
    • 角色:dbOwner

且服务端mongod正在运行了

下面是如何去连接该远程的mongo数据库几种方式:

服务器中本地连接

服务器上本地客户端:mongo shell

[root@xxx-general-01 ~]# mongo --port 32018
MongoDB shell version: 3.2.19
connecting to: 127.0.0.1:32018/test

进去后再:

use gridfs
db.auth("gridfs", "password")

或者直接:

mongo gridfs --port 32018 -u gridfs -p password --authenticationDatabase gridfs

Mac本地连接远端MongoDB

Mac中本地mongo shell去连接远程MongoDB

以gridfs用户去登录

以用户gridfs去登录,且(限定了)只(能)访问数据库gridfs:

mongo 47.96.131.109:32018/gridfs  -u gridfs -p password --authenticationDatabase gridfs

或:

mongo gridfs --host 47.96.131.109 --port 32018  -u gridfs -p password --authenticationDatabase gridfs

以admin用户去登录

以用户admin去登录,没有限定访问哪个数据库(后续则可以访问其他数据,前提是admin本身有这个权限):

mongo --host 47.96.131.109 --port 32018 -u root -p pwd --authenticationDatabase admin

Python的pymongo代码连接远程MongoDB

import pymongo
from pymongo import MongoClient
import gridfs

# from pymongo.objectid import ObjectId
# from pymongo import objectid
from bson.objectid import ObjectId

from gridfs import GridFS

MongoHost = "47.96.131.109"
MongoPort = 32018

MongoUseAuth = True
# MongoUseAuth = False

# with auth
MongoUsername = "gridfs"
MongoPassword = “password"
MongoAuthenticationDatabase = "gridfs"

mongodbUri = ""
if MongoUseAuth :
    mongodbUri = "mongodb://%s:%s@%s:%s/%s" % (
        quote_plus(MongoUsername), \
        quote_plus(MongoPassword), \
        MongoHost, \
        MongoPort, \
        MongoAuthenticationDatabase \
    )
    #'mongodb://gridfs:password@47.96.131.109:32018/gridfs'
else:
    mongodbUri = "mongodb://%s:%s" % (
        MongoHost, \
        MongoPort
    )
    #'mongodb://localhost:32018'
    #'mongodb://47.96.131.109:32018’

mongoClient = MongoClient(mongodbUri)
gridfsDb = mongoClient.gridfs
fsCollection = GridFS(gridfsDb)

PyCharm中mongo4idea中的连接远端MongoDB

配置参数:

  • General
    • 截图:
      • mongo4idea_config_general
    • 文字:
      • Server url(s):47.96.131.109:32018
      • User Database:gridfs
  • Authentication
    • 截图:
      • mongo4idea_config_authentication
    • 文字:
      • Username:gridfs
      • Password:your_password
      • Auth. database:gridfs
      • Auth. mechanism:SCRAM-SHA-1

即可成功连接:

mongo4idea_test_connection_successful
