MongoDB的授权和权限 1. 在开启MongoDB 服务时不添加任何参数时,可以对数据库任意操作,而且可以远程访问数据库。如果启动的时候指定auth参数,可以对数据库进行用户验证。 www.2cto.com $ ./mongod --auth mongodb.log 开启 ./mongo MongoDB shell version


MongoDB的授权和权限

 

1. 在开启MongoDB 服务时不添加任何参数时,可以对数据库任意操作,而且可以远程访问数据库。如果启动的时候指定—auth参数,可以对数据库进行用户验证。  www.2cto.com  

           $ ./mongod --auth >> mongodb.log & 开启 

           ./mongo 

MongoDB shell version: 1.8.1 

connecting to: test 

>show dbs 

admin   (empty) 

local   (empty) 

 

2. 添加用户 

在刚安装完毕的时候MongoDB都默认有一个admin数据库,而admin.system.users中将会保存比在其它数据库中设置的用户权限更大的用户信息。 

当admin.system.users中一个用户都没有时,即使mongod启动时添加了--auth参数,如果没有在admin数据库中添加用户,此时不进行任何认证还是可以做任何操作,直到在admin.system.users中添加了一个用户。 

 

下面创建数据库tage,并给tage创建用户: 

> use tage   

switched to db tage 

> db.addUser("tage","123") 

         "user" : "tage", 

         "readOnly" : false, 

         "pwd" : "1f66d5c4223029536080d41febe0ec33" 

在admin库中创建root用户: 

> use admin 

switched to db admin 

> db.addUser("root","123456") 

         "user" : "root", 

         "readOnly" : false, 

         "pwd" : "34e5772aa66b703a319641d42a47d696" 

3. 验证用户: 

> db.auth("root","123") 

0                    密码错误,返回0,验证失败 

> db.auth("root","123456")  

1                                            验证成功,返回1 

 

下面试验用户权限设置: 

$ ./mongo       登录时不加用户名与密码 

MongoDB shell version: 1.8.1 

connecting to: test 

> use tage 

switched to db tage 

> db.system.users.find() 

error: { 

         "$err" : "unauthorized db:tage lock type:-1 client:127.0.0.1", 

         "code" : 10057 


 

4. 以上验证说明,登录时不指定用户名与密码,就会报错。下面指定用户与密码 

$ ./mongo -uroot -p123456  指定用户与密码,但是不指定库名 

MongoDB shell version: 1.8.1 

connecting to: test 

Wed Aug  3 21:30:42 uncaught exception: login failed 

exception: login failed 

mongodb登录时默认连接test库,如果登录时不指定库名,就会报错 

 

5. 下面以tage库的用户名登录进行验证: 

$ ./mongo tage -utage -p123 

MongoDB shell version: 1.8.1 

connecting to: tage 

> db.system.users.find()    对所属自己的库进行操作,有权限 

{ "_id" : ObjectId("4e394c696b50a56254359088"), "user" : "tage", "readOnly" : false, "pwd" : "1f66d5c4223029536080d41febe0ec33" } 

> use admin 

switched to db admin 

> db.system.users.find() 对其他库操作,没有权限 

error: { 

         "$err" : "unauthorized db:admin lock type:-1 client:127.0.0.1", 

         "code" : 10057 

6. 下面以admin库下的root用户登录进行验证: 

./mongo admin -uroot -p123456 

MongoDB shell version: 1.8.1 

connecting to: admin 

> db.system.users.find() 

{ "_id" : ObjectId("4e394caf6b50a56254359089"), "user" : "root", "readOnly" : false, "pwd" : "34e5772aa66b703a319641d42a47d696" } 

> use tage 

switched to db tage 

> db.system.users.find()   对其他库进行操作,有权限 

{ "_id" : ObjectId("4e394c696b50a56254359088"), "user" : "tage", "readOnly" : false, "pwd" : "1f66d5c4223029536080d41febe0ec33" } 

 

7. mongodb的远程用户连接 

语法结构:mongo –uusername –ppwd ServerIP:port/dbname 

其中port默认为27017 

$ ./mongo  -uroot -p123456 192.168.2.150/admin 

MongoDB shell version: 1.8.1 

connecting to: 192.168.2.150/admin 

> db.system.users.find() 

{ "_id" : ObjectId("4e394caf6b50a56254359089"), "user" : "root", "readOnly" : false, "pwd" : "34e5772aa66b703a319641d42a47d696" }

How do you create and manage user accounts in MySQL?How do you create and manage user accounts in MySQL?Apr 22, 2025 pm 06:05 PM

The steps to create and manage user accounts in MySQL are as follows: 1. Create a user: Use CREATEUSER'newuser'@'localhost'IDENTIFIEDBY'password'; 2. Assign permissions: Use GRANTSELECT, INSERT, UPDATEONmydatabase.TO'newuser'@'localhost'; 3. Fix permission error: Use REVOKEALLPRIVILEGESONmydatabase.FROM'newuser'@'localhost'; then reassign permissions; 4. Optimization permissions: Use SHOWGRA

What are the disadvantages of using MySQL compared to other relational databases?What are the disadvantages of using MySQL compared to other relational databases?Apr 22, 2025 pm 05:49 PM

The disadvantages of MySQL compared to other relational databases include: 1. Performance issues: You may encounter bottlenecks when processing large-scale data, and PostgreSQL performs better in complex queries and big data processing. 2. Scalability: The horizontal scaling ability is not as good as Google Spanner and Amazon Aurora. 3. Functional limitations: Not as good as PostgreSQL and Oracle in advanced functions, some functions require more custom code and maintenance.

How do you perform a JOIN operation in MySQL?How do you perform a JOIN operation in MySQL?Apr 22, 2025 pm 05:41 PM

MySQL supports four JOIN types: INNERJOIN, LEFTJOIN, RIGHTJOIN and FULLOUTERJOIN. 1.INNERJOIN is used to match rows in two tables and return results that meet the criteria. 2.LEFTJOIN returns all rows in the left table, even if the right table does not match. 3. RIGHTJOIN is opposite to LEFTJOIN and returns all rows in the right table. 4.FULLOUTERJOIN returns all rows in the two tables that meet or do not meet the conditions.

How does MySQL's performance compare to other RDBMS under high load?How does MySQL's performance compare to other RDBMS under high load?Apr 22, 2025 pm 05:37 PM

MySQL's performance under high load has its advantages and disadvantages compared with other RDBMSs. 1) MySQL performs well under high loads through the InnoDB engine and optimization strategies such as indexing, query cache and partition tables. 2) PostgreSQL provides efficient concurrent read and write through the MVCC mechanism, while Oracle and Microsoft SQLServer improve performance through their respective optimization strategies. With reasonable configuration and optimization, MySQL can perform well in high load environments.

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
