MongoDB创建数据库和用户

step 1. 为mongodb添加admin管理员
root@12.154.29.163:~
# mongo

MongoDB shell version v3.4.2
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.2
> use admin
switched to db admin
> db.createUser({
... user:'admin',
... pwd:'admin',
... roles:[{ role: "userAdminAnyDatabase", db: "admin" }]
...})
Successfully added user: {
    "user" : "dba",
    "roles" : [
        {
            "role" : "userAdminAnyDatabase",
            "db" : "admin"
        }
    ]
}

step 2. 修改mongod.conf配置文件
# vi /etc/mongod.conf 
//去掉注释
security:
  authorization: enabled
# service mongod restart
# mongo

step 3. 为album添加用户
MongoDB shell version v3.4.2
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.2
> use admin
switched to db admin
> db.auth('admin','admin')
1
> show dbs
admin  0.000GB
local  0.000GB
> use album
switched to db album
> show collections    //结果为空
> db.foo.insert({_id:1,name:"test"})
WriteResult({ "nInserted" : 1 })
> show collections
foo
> db.createUser({
... user:'admin',
... pwd:'admin',
... roles:['readWrite']
... })
Successfully added user: { "user" : "admin", "roles" : [ "readWrite" ] }
> exit
bye

Tips：
  1.添加的管理员或者用户名称都为：admin，但是对应的数据库不同
  2.mongoDB之前的版本，用addUser
  3.更多详细操作示例可参见：http://www.cnblogs.com/zhoujinyi/p/4610050.html
