mongodb3.x认证

MongoDB-CR
Authentication failed的解决方法：

use admin
db.system.users.remove({})    <== removing all users
db.system.version.remove({}) <== removing current version
db.system.version.insert({ "_id" : "authSchema", "currentVersion" : 3 })

创建账号：
db.createUser( { "user" : "lsy",

"pwd": "root",

"roles" : [ { role: "clusterAdmin", db: "admin" },

{ role: "readAnyDatabase", db: "admin" },

"readWrite"

] },

{ w: "majority" , wtimeout: 5000 } )

然后就可以用用户lsy和密码root进行登录了
可参考这篇文章http://docs.mongodb.org/master/reference/method/db.createUser/

在Windows上编译时需要加上”–64”命令，否则会出现”error : You cannot
use 32-bit time_t (_USE_32BIT_TIME_T) with _WIN64”错误，这个是MongoDB的BUG
