首先先晒一下log 日志错误信息

2016-07-13T22:19:43.667+0800 I ACCESS   [conn4]  authenticate db: finddemo { aut
henticate: 1, nonce: "xxx", user: "user1", key: "xxx" }

着重看一下 这个报错信息，

SCRAM-SHA-1 authentication failed for user1 on finddemo

这是什么鸟？   

mongodb加入了SCRAM-SHA-1校验方式，需要第三方工具配合进行验证，下面给出具体解决办法： 

首先关闭认证，修改system.version文档里面的authSchema版本为3，初始安装时候应该是5，命令行如下： 

> use admin 
switched to db admin 
>  var schema = db.system.version.findOne({"_id" : "authSchema"}) 
> schema.currentVersion = 3 
3 
> db.system.version.save(schema) 
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 })

 

 

下面是获取到的用户的相关信息

{ "_id" : "admin.root", "user" : "root", "db" : "admin", "credentials" : { "MONGODB-CR" : "97a156792bd180dc82cec9a56d838991" }, "roles" : [ { "role" : "__system", "db" : "admin" } ] }
{ "_id" : "finddemo.finddemo", "user" : "finddemo", "db" : "finddemo", "credentials" : { "MONGODB-CR" : "4b8dce39de95d553473c1998f43aa165" }, "roles" : [ { "role" : "dbOwner", "db" : "finddemo" } ] }

 

重新连接，成功。
