首先说中心思想,和连接本地数据库是一样的,不同的是修改数据库的配置项:
module.exports = { dbs:'mongodb://账号:密码@服务器ip27017/数据库名称' }
但是总是提示权限不足。
即在要操作的数据库 dbs下创建用户的读写权限,例如:
use dbs db.createUser({ user:'root', pwd:'root', roles:[ {role:'readWrite',db:'dbs'} ] })
每个数据库,都要设置用户的访问权限,只有设置了权限,才能对数据库进行操作!
详见这篇文章:http://www.ttlsa.com/mongodb/mongodb-3-0-security-permissions-access-control/
mongoDB 3.0 访问控制改了很多,需要你老老实实的去看文档去验证,谷歌百度出来的多半就是错误的。 还需要注意这个参数authenticationMechanisms。
为了兼用2.6版本,我直接指定下面的参数:

setParameter:
authenticationMechanisms: MONGODB-CR

下面看看如何创建访问控制权限
不使用 —auth 参数,启动 mongoDB

mongodb-linux-i686-3.0.0/bin/mongod -f mongodb-linux-i686-3.0.0/mongodb.conf
|
此时你 show dbs 会看到只有一个local数据库,那个所谓的admin是不存在的。
mongoDB 没有超级无敌用户root,只有能管理用户的用户 userAdminAnyDatabase。
添加管理用户

use admin
db.createUser(
{
user: "buru",
pwd: "12345678",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
}
)
|
roles 中的 db 参数是必须的,不然会报错:Error: couldn’t add user: Missing expected field “db”。另外,有很多文章记录的是使用 db.addUser(…) 方法,这个方法是旧版的,3.0中已经不存在,详见:http://docs.mongodb.org/manual/reference/method/js-user-management。
切换到admin下,查看刚才创建的用户:

show users
或
db.system.users.find()
{ "_id" : "admin.buru", "user" : "buru", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "gwVwuA/dXvxgSHavEnlyvA==", "storedKey" : "l2QEVTEujpkCuqDEKqfIWbSv4ms=", "serverKey" : "M1ofNKXg2sNCsFrBJbX4pXbSgvg=" } }, "roles" : [ { "role" : "userAdminAnyDatabase", "db" : "admin" } ] }

怎么关闭 mongoDB?千万不要 kill -9 pid,可以 kill -2 pid 或 db.shutdownServer()
下面使用 —auth 参 数,重新启动 mongoDB:

mongodb-linux-i686-3.0.0/bin/mongod --auth -f mongodb-linux-i686-3.0.0/mongodb.conf
mongodb-linux-i686-3.0.0/bin/mongo
use admin
db.auth("buru","12345678") #认证,返回1表示成功
或
mongodb-linux-i686-3.0.0/bin/mongo -u buru -p 12345678 --authenticationDatabase admin
