MongoDB数据库用户名和密码的设置
作者:网络转载 发布时间:[ 2015/10/27 11:07:20 ] 推荐标签:MongoDB 数据库
首先是对MongoDB用户和权限的设置,如果不设置用户的话,直接使用mongo命令可以进入客户端shell界面进行操作了,但是如果没有设置用户的话,总感觉少了点什么,于是经过半天的查找和实践,差不多把用户和权限弄明白了。总结如下:
如果按照以下这个指令安装的话:
mongod --install --dbpath "C:Program Filesmongodbdatadb" --logpath "C:Program FilesmongodbdatalogMongoDB.log"
如下:
c:Program Filesmongodbin>mongod --install --dbpath "C:Program Filesmongodbdatadb" --logpath "C:Program FilesmongodbdatalogMongoDB.log"

Server has startup warnings:

可以看到有两个默认的数据库admin和local
实例1:创建一个用户名为root,密码为admin的用户,如下:
> use admin
switched to db admin
> db.addUser("root","admin")
{
"user" : "root",
"readOnly" : false,
"pwd" : "bde0d84f6749c235a6b4e36d945eb666",
"_id" : ObjectId("515e662430d89f61f6991c91")
}
> show collections
Fri Apr 05 13:50:36.685 JavaScript execution failed: error: {
"$err" : "not authorized for query on admin.system.namespaces",
"code" : 16550
} at src/mongo/shell/query.js:L128
>
说明:使用以上指令show collections的时候,发现报错了。是因为没有权限。做如下操作:
> db.auth("root","admin");
1
说明:返回1表示验证成功了,返回0表示验证失败。
此时,输入以下指令:show collections则可以看到admin下的集合了。
> show collections
system.indexes
system.users
> db.system.users.find()
{ "_id" : ObjectId("515e662430d89f61f6991c91"), "user" : "root", "readOnly" : false, "pwd" : "bde0d84f6749c235a6b4e36d945eb666" }
>
实例2:在用户名为root,密码为admin的用户下创建一个student数据库,并在student数据库中创建一个stu的集合并插入一个文档,如下:
> use student
switched to db student
> db.stu.insert({"name":"maoyuanjun","age":25,"sex":"male"})
> db.stu.find()
{ "_id" : ObjectId("515e676630d89f61f6991c92"), "name" : "maoyuanjun", "age" : 25, "sex" : "male" }
退出服务器,重新登陆如下:
c:Program Filesmongodbin>mongo
MongoDB shell version: 2.4.1
connecting to: test
> show dbs
Fri Apr 05 13:58:05.420 JavaScript execution failed: listDatabases failed:{ "ok" : 0, "errmsg" : "unauthorized" }
at src/mongo/shell/mongo.js:L46
出错原因:是没有权限。则先判断是否有权限,如下:
> use admin
switched to db admin
> db.auth("root","admin")
1
> show dbs
admin 0.0625GB
local 0.03125GB
student 0.0625GB
>
这时,我们可以看到用户root,密码admin的用户下多了一个student数据库。
