1.首先要创建数据库

use chunqiu

2.创建用户授予权限，在创建用户之前首先了解下mongodb中的role功能，那么admin数据库中有哪些role 呢？

查看role：

use admin

PRIMARY> show roles
{
    "role" : "__system",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "backup",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "clusterAdmin",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "clusterManager",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "clusterMonitor",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "dbAdmin",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "dbAdminAnyDatabase",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "dbOwner",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "enableSharding",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "hostManager",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "read",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "readAnyDatabase",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "readWrite",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "readWriteAnyDatabase",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "restore",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "root",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "userAdmin",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "userAdminAnyDatabase",
    "db" : "admin",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}

那么chunqiu的库有哪些role呢？

use chunqiu

PRIMARY> show roles
{
    "role" : "dbAdmin",
    "db" : "chunqiu",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "dbOwner",
    "db" : "chunqiu",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "enableSharding",
    "db" : "chunqiu",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "read",
    "db" : "chunqiu",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "readWrite",
    "db" : "chunqiu",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
{
    "role" : "userAdmin",
    "db" : "chunqiu",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}

3.看完了mongodb的role后是不是感觉豁然开朗？那么现在就创建用户吧：

use chunqiu
db.createUser(
  {
    user: "app_user",
    pwd: "app#password",
    roles:
    [
      {
        role: "dbOwner",    ##数据库权限的role选择dbOwner
        db: "chunqiu"          ##注意此处数据验证使用chunqiu库
      }
    ]
  }
)

如果要建只读账号：
use chunqiu
db.createUser(
  {
    user: "app_user_read",
    pwd: "read#password",
    roles:
    [
      {
        role: "read",                   ##数据库权限的role选择read
        db: "chunqiu"
      }
    ]
  }
)

查看已经创建的用户：

show users

修改密码：

db.changeUserPassword('app_user','password');

授予角色：
db.grantRolesToUser( "admin" , [ { role: "dbAdminAnyDatabase", db: "admin" } ])

取消角色：
db.revokeRolesFromUser( "admin" , [ { role: "dbAdminAnyDatabase", db: "admin" } ])

4.最后你可以把创建的账号和密码发给开发人员使用了。
