示例

mongo  -u 用户名 -p 密码  服务器地址:端口号

//指定用户名和密码连接到指定的MongoDB数据库
mongo 192.168.1.200:27017/test -u user -p password

注意：

3.4版本认证连接需要指定认证的数据库，即 “–authenticationDatabase”参数。

使用mongo命令进行连接，指定服务器地址及端口号，用户名-u，密码-p。

若没有设置用户认证，则不需要用户名及密码两个参数。

mongo --authenticationDatabase admin -u 用户名 -p 密码  服务器地址:端口号

注：若未指定–authenticationDatabase 参数，此版本的mongodb会报错：

_MongoDB server version: 3.4.17  
2018-12-03T12:40:36.976+0800 E QUERY    [thread1] Error: Authentication failed. :  DB.prototype._authOrThrow@src/mongo/shell/db.js:1459:20  
@(auth):6:1  
@(auth):1:2  
exception: login failed

第二种连接方式如下

mongo 192.168.0.1:27017/库名 -u 用户名 -p 密码

mongo “10.122.236.14:27019/bucketadm” -u “bucketadm-user-read” -p “m8readuserbucketadm7lwiRVu1Sfs65drg”
