mongodb管理Security and Authentication
mongdb自己也提供了验证机制,如果不验证是无法访问数据库对象,一个数据可以有多个用户,用户的权限也可以各不相同,下面具体介绍一下。
> use admin ----登录到超级管理员
>db.addUser("root", "abcd");
{
"_id" : ObjectId("4eaf58af769d879418d93191"),
"user" : "root",
"readOnly" : false,
"pwd" : "1a0f1c3c3aa1d592f490a2addc559383"
}
创建了一个超级用户,这个用户可以访问任何数据库,权限最大
> use test
switched to db test 切换到test数据库
> db.addUser("test_user", "efgh");
{
"user" : "test_user",
"readOnly" : false,
"pwd" : "6076b96fc3fe6002c810268702646eec"
}
> db.addUser("read_only", "ijkl", true);
{
"user" : "read_only",
"readOnly" : true,
"pwd" : "f497e180c9dc0655292fee5893c162f1"
}
以上创建两个用户,test_user和read_only,不同的是,read_only用户只有只读权限
> use test
switched to db test
> db.test.find();
error: { "$err" : "unauthorized for db [test] lock type: -1 " }
> db.auth("read_only", "ijkl");
1
> db.test.find();
{ "_id" : ObjectId("4bb007f53e8424663ea6848a"), "x" : 1 }
> db.test.insert({"x" : 2});
unauthorized
> db.auth("test_user", "efgh");
1
> db.test.insert({"x": 2});
> db.test.find();
{ "_id" : ObjectId("4bb007f53e8424663ea6848a"), "x" : 1 }
{ "_id" : ObjectId("4bb0088cbe17157d7b9cac07"), "x" : 2 }
以上例子可以看到没有验证用户登录,对数据库读写操作均不能,read_only用户只能查询,不能插入,但是test_user用户验证登录后就可以插入了。
如果这时,show dbs,还是报错,因为test_user 不是admin用户,所以没有权限。
> use admin
switched to db admin
> db.auth("root", "abcd");
1
> show dbs
admin
local
test
验证了超级用户就可以做相关操作
创建的这些用户都存在创建时数据库下面一个叫system.users的集合里面,如果要移除一个user,例如移除test_user
> db.auth("test_user", "efgh");
1
> db.system.users.remove({"user" : "test_user"});
> db.auth("test_user", "efgh");

启用验证登录:如果是配置文件启动server端,里面可以加入auth = true ,如果是跟参数启动mongod 后面记得跟--auth。

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.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
